Imagine a startup CTO staring at two things: a rapidly growing cloud bill and a stack of perfectly functional older servers sitting idle. For many tech leaders, the public cloud’s promise of on-demand scalability meets a harsh reality when costs balloon or sensitive data can’t leave the premises. Enter an unexpected hero: refurbished servers. An emerging strategy is to blend these previously owned machines with cloud services, creating a hybrid infrastructure that balances cost, performance, and control. In fact, some companies have found such setups so cost-effective that they’ve dramatically cut expenses — 37signals (maker of Basecamp) estimates saving $7 million over five years by pulling much of its workload off the public cloud.. The lesson is clear: done right, combining old-but-good hardware with the cloud can unlock the best of both worlds, stretching budgets and even advancing sustainability goals.

Refurbished Servers: Cutting Costs and Carbon Footprints

Why consider refurbished servers at all? The first answer is cost. Pre-owned, professionally refurbished servers often come at a fraction of the price of new hardware. We’re talking 50–70% cheaper than buying brand-new, according to industry comparisons.. That means a startup or IT department can get enterprise-grade compute power without the enterprise-grade price tag. Every dollar saved on hardware is a dollar that can be invested elsewhere — whether hiring developers or expanding marketing. It’s no wonder even cloud-native companies have rethought the “all cloud, all the time” approach when the economics tip in favor of owning servers. Dropbox, for example, famously saved nearly $75 million in two years by shifting storage from AWS to its own infrastructure.. While not everyone operates at Dropbox’s scale, the underlying principle holds: renting compute by the hour can be far more expensive in the long run than owning the capacity outright for steady workloads.

The second answer is sustainability. Using refurbished hardware is essentially a form of recycling, and it carries significant environmental benefits. Modern servers take a lot of energy and resources to manufacture — a server’s carbon footprint begins before it ever powers on, due to the energy required to mine raw minerals and fabricate chips and components.. Extending the life of existing servers avoids that embodied carbon cost. In fact, choosing refurbished over new can slash carbon emissions by up to 80%, while also reducing e-waste and raw material use. For organizations looking to shrink their IT carbon footprint, this is a big win. It aligns with circular economy principles: reuse instead of dispose. Companies can meet sustainability targets not just by how they use servers, but by what hardware they use. Even the tech giants have caught on. Microsoft, for one, has opened “circular centers” to refurbish its cloud servers and aims to reuse 90% of its server components by 2025. This kind of initiative highlights a growing industry consensus that yesterday’s hardware can play a key role in tomorrow’s infrastructure — responsibly and cost-effectively.

From Cloud Bursts to Edge AI: Hybrid Models in Practice

Blending refurbished servers with the cloud doesn’t mean abandoning cloud benefits. On the contrary, a well-designed hybrid infrastructure lets you cherry-pick the strengths of each. Here are some common hybrid models and use cases that illustrate how the combo can work:

• Cloud Bursting for Peaks: In this model, your refurbished on-premises servers handle the steady baseline load, and you “burst” into the public cloud only when demand spikes beyond local capacity. For example, an e-commerce site might run day-to-day operations on its own servers, then temporarily tap cloud servers during a holiday traffic surge. This approach means you pay the cloud provider only for extra capacity when needed, avoiding the cost of over-provisioning hardware for rare peaks. It’s the classic hybrid analogy of using a reliable old car for daily commutes and hailing a taxi only on the few days you need to. Cloud bursting gives flexibility without paying for cloud idle time.
• Edge Computing and Low-Latency Needs: Not all computing happens in a central data center or cloud region. Often data is generated and used in the field — think retail stores, factories, or remote sensors. Refurbished servers can be deployed at these edge locations to process data on-site (reducing latency and bandwidth usage) while the cloud handles centralized analytics and coordination. For instance, a factory might process machine sensor data on a local server in real time and send summarized results to a cloud dashboard. This hybrid edge setup is increasingly important; by the end of 2025, analysts estimate 75% of enterprise data will be created outside traditional central data centers (much of it at the edge). Using cost-effective refurbished hardware for these distributed nodes makes scaling to dozens or hundreds of edge sites far more affordable. The cloud then acts as the hub for aggregating and learning from all that distributed data.
• Compliance and Data Sovereignty: Certain data or workloads just can’t go to the public cloud, whether for legal, security, or privacy reasons. Hybrid infrastructure is a natural fit in regulated industries like finance or healthcare. An organization can keep sensitive customer records or critical databases on hardened refurbished servers in a private data center (or colocation facility) to meet compliance requirements, while still using the public cloud for less sensitive functions (such as running a public-facing web application or mobile app backend). In this model, on-prem and cloud systems are integrated but clearly demarcated by data sensitivity. The result is a compliant architecture that doesn’t sacrifice the agility of cloud for non-regulated parts of the stack.
• Dev/Test and Specialized Workloads: Hybrid setups also shine in development and testing scenarios. Instead of paying for transient cloud VMs every time developers spin up a new test environment, a company might repurpose a few older servers as an internal sandbox or continuous integration cluster. Refurbished machines are perfect for these lab environments — they deliver plenty of compute for most testing needs at minimal cost, and engineers can experiment freely without racking up usage fees. Once testing is done, the final product can be deployed to the cloud (or to production on-prem) as appropriate. Similarly, teams working with specialized workloads (say, an AI research group) might use a couple of refurbished GPU servers locally for prototyping models, avoiding the extremely high hourly rates of cloud GPU instances. It’s a way to give developers and researchers the resources they need on-demand, but under a fixed budget. Many organizations find this hybrid dev/test approach markedly improves productivity and cost control.

In all these models, the philosophy is to run each workload where it makes the most sense. Your own servers handle the parts that are predictable, sensitive, or cost-critical, while the cloud’s vast resources are there as a safety net and scale booster. The beauty of hybrid infrastructure is this flexibility. You might even dynamically shift workloads between environments — for example, developing in the cloud then deploying on-prem, or vice versa — depending on economics or timing. The cloud vendors recognize the trend, with tools to help connect on-premises environments to their clouds more seamlessly. The result, when done well, is an IT strategy that optimizes for both cost and capability. Organizations that embrace this kind of hybrid thinking often see tangible benefits; in fact, a recent survey found that companies using hybrid cloud reported better ROI and faster adoption of new technologies than those sticking solely to all-cloud or all on-prem approaches.. It appears that mixing and matching infrastructure isn’t just a compromise — it can be a competitive advantage.

Refurbished Hardware: Debunking the Common Myths

Despite the advantages, some decision-makers hesitate at the word “refurbished.” It brings to mind images of unreliable, outdated machines. However, many of the concerns around refurbished servers are outdated themselves. Let’s tackle a few common myths head-on:

Myth: “Refurbished servers are unreliable and will fail on me.”

Reality: Quality refurbished servers go through rigorous testing and restoration processes to ensure reliability. Reputable refurbishers replace any faulty components, clean and recondition the unit, and run stress tests before certifying a server for sale. In practice, a refurbished server that’s been properly vetted can perform just as dependably as a new one. Many come with official certification and have to meet industry standards for performance and stability.. In other words, these aren’t random used boxes sold at a flea market — they’re often enterprise-grade machines given a new lease on life, typically backed by guarantees (more on that in a moment). With proper maintenance, refurbished hardware can run critical workloads for years without issue, just as new hardware would.

Myth: “Using old hardware is a security risk.”

Reality: It’s a valid concern that outdated equipment might miss out on security updates, but refurbished servers, by definition, are wiped clean and restored to factory settings or updated firmware. From that point forward, they can run the latest operating systems and receive all the same security patches a new server would. A server doesn’t become inherently insecure just because of its age — what matters is the software it runs and how it’s configured. When you buy from a trustworthy source, all previous data is securely erased and the machine is ready to be configured to your security standards. Of course, you should apply all recommended patches and harden the OS, same as you would on a brand-new server. It’s also wise to check that the hardware is not too old — for example, very old CPUs might lack certain modern security features or firmware-level fixes for recent vulnerabilities. But most refurbished servers on the market are only a generation or two behind the cutting edge, and they can be operated with strong security postures. In short, a refurbished server in your own rack can be just as secure as a cloud VM, provided you manage it well.

Myth: “No warranty or support — you’re on your own if it breaks.”

Reality: This might have been true in the Wild West days of second-hand IT gear, but not anymore. Today, leading refurbishers and secondary market providers often include multi-year warranties on refurbished servers, and offer support contracts akin to those for new hardware. It’s common to get a one- to three-year warranty on refurbished enterprise servers, and some vendors even offer extended coverage beyond that. This means you have recourse if a component fails — replacement parts or units are typically provided, minimizing downtime. Additionally, because refurbished hardware is so affordable, some organizations buy extra units as spares or for parts, creating a safety net that’s still cheaper than buying new. Many major manufacturers also have their own certified refurbished programs (for example, HPE Renew or Dell Outlet), which re-condition used gear and back it with official support. The bottom line: you’re not flying blind with refurbished servers. With the right vendor, you’ll have support and warranties ensuring your investment is protected, just as you would with new equipment.

By dispelling these myths, it becomes clear that “refurbished” doesn’t mean subpar. It simply means you’re not the first owner. The performance, reliability, and security can be on par with new machines, especially if you stick to reputable sources. And with myths out of the way, the conversation can shift to what really matters: how to operationalize a hybrid strategy that leverages these assets.

Nuts and Bolts: Operational and Security Considerations

Designing a hybrid infrastructure with some on-premises hardware (refurbished or otherwise) and some in the cloud does introduce complexity. It’s important to go in with eyes open about the operational and security implications. Here are a few key considerations and best practices for making a hybrid setup successful:

Maintenance and monitoring: In the cloud, hardware failures and maintenance are abstracted away — your cloud provider quietly replaces failing drives or servers behind the scenes. When you run your own servers, you assume that responsibility. This means you’ll need a plan for monitoring the health of your machines (CPU, memory, disk, network, etc.) and responding to issues. Thankfully, there are plenty of tools (from open-source solutions to commercial data center monitoring systems) to help with this. Ensure you have alerting in place for things like disk failures or high temperatures. It’s wise to keep some spare components or even entire spare servers on hand, especially since refurbished units are inexpensive — if one goes down, you can swap in a replacement quickly. Alternatively, consider using a colocation provider or managed service, where your servers live in a professional data center facility and possibly under the watch of on-site technicians. That can give you reliable power, cooling, and physical security, as well as hands-on support if you can’t personally be where the servers are 24/7.

Network and connectivity: A hybrid infrastructure is only as good as the connectivity between its parts. You’ll need a secure, low-latency link between your on-prem servers and the cloud environment. This could be a VPN over the public internet or a dedicated direct connection offered by the cloud provider. Plan network capacity so that data transfers don’t become a bottleneck. For example, if your local servers are constantly syncing large amounts of data to the cloud, ensure you have sufficient bandwidth (and consider the egress costs cloud providers charge for data out — those can add up). Architect your applications with latency in mind: keep interactions between the on-prem and cloud components as efficient as possible. A chatty application that has to reach across the internet for every little request will suffer in performance. Instead, design such that only periodic or bulk data transfers occur between the cloud and your own servers, or use caching and local processing to minimize back-and-forth. Essentially, treat the cloud-to-datacenter link as a critical component and invest in making it secure and robust.

Patching and updates: One responsibility that returns when you manage your own machines is handling software updates — both at the OS level and for firmware. You’ll need to apply security patches to your server operating systems just as you would for any self-hosted system. Set up a regular patch schedule or use automation (configuration management or services like WSUS for Windows, etc.) to keep everything up to date. Don’t neglect firmware and BIOS updates for your hardware as provided by the OEM or refurbisher; these can fix bugs and security issues (for example, certain CPU vulnerabilities can be partially mitigated by BIOS updates). The good news is refurbished servers from reputable vendors should start you off on current firmware, and as noted, they can receive the same updates new machines do.. Just incorporate your on-prem nodes into whatever patch management regimen your IT team follows. This way, your hybrid cloud won’t develop a weak link on-prem due to forgotten updates.

Security best practices: Operating your own hardware means you’re in charge of physical and network security for that portion of the system. Physically, ensure servers are in a locked environment with access control — whether it’s a dedicated server room or a locked cabinet in a colocation data center. Only authorized personnel should touch them. Network-wise, extend your cloud’s security perimeter to include the on-prem servers: use firewalls to limit inbound/outbound traffic, and encrypt data in transit between cloud and on-prem (VPN tunnels with strong encryption, SSL/TLS for any service communication, etc.). Apply the principle of least privilege across both environments. Also, consider the data on those refurbished servers: implement disk encryption if appropriate, and have a solid backup strategy that covers data in both places. One common approach is to back up on-prem data to cloud storage or vice versa, to ensure that a failure or breach in one environment doesn’t lead to total data loss. In a hybrid scenario, you must coordinate security policies between your cloud and your own infrastructure — identity and access management, logging, audit trails — so that you maintain a holistic view of your system’s security. Misconfigurations often happen at the seams of hybrid setups, so double-down on those seams (for instance, ensure your cloud keys or credentials are stored safely on the on-prem side and that any APIs tying the two parts together are secure).

Performance and capacity planning: Just as you would with a purely on-prem deployment, keep an eye on the capacity of your refurbished servers. Cloud can instantly cover any shortfall if you architect for it (that’s the whole idea of bursting), but you still want to prevent local bottlenecks. Use monitoring to know when you’re nearing the limits of your on-prem hardware and either scale up (perhaps by adding more refurbished nodes) or scale out to cloud in a more sustained way. One nice aspect of using refurb servers is that adding more capacity is relatively cheap — you might keep an extra server or two powered off as hot spares or for quick capacity adds during a growth phase, then bring them online as needed. Also account for the fact that older hardware might not be as power-efficient; ensure your power and cooling environment can handle the heat output. In some cases, extremely power-hungry legacy servers could diminish the cost savings (via higher electric bills), so it’s something to balance — often still a net win financially, but worth evaluating if you have very old models.

In summary, running a hybrid cloud that includes refurbished servers does require more hands-on work than an all-cloud approach. However, none of the tasks are extraordinary — they’re the same IT management practices data centers have followed for decades. With good planning and modern automation/orchestration tools, even a small team can comfortably manage a fleet of on-prem servers alongside cloud resources. The key is to treat the hybrid environment as one integrated system: apply strong DevOps practices across both, maintain consistency in configurations, and keep security and monitoring tight everywhere. Do that, and you can reap the cost and control benefits of owning hardware without letting the operational burden overwhelm you.

From Startups to Tech Giants: Hybrid Infrastructure in Action

Hybrid strategies that mix refurbished gear and cloud services are not just theoretical — they’re happening in the wild across the industry. We’ve already touched on a couple of high-profile examples (like 37signals and Dropbox) that underscore the potential savings. But there are many other instances, at organizations big and small, proving this model’s viability:

• Cost-savvy enterprises: According to one report, a major e-commerce company managed to reduce its data center costs by 40% while meeting sustainability goals simply by opting for refurbished hardware over new.. In another case, a cloud services provider (ironically, a company that provides cloud infrastructure to others) decreased its carbon footprint by 65% over three years by transitioning much of its own backend infrastructure to refurbished servers. And a financial institution saved about $2 million annually by extending the life of its IT equipment via a comprehensive refurbishment program. These examples show that the benefits scale from the tech startup world into more traditional industries as well — cost savings and sustainability aren’t niche concerns; they’re universal.
• Tech giants repatriating workloads: Even some born-in-the-cloud companies have publicly moved toward hybrid or on-prem models to control costs. We mentioned Dropbox, which built out private infrastructure and saved roughly $75 million in operating expenses in two years. That move involved investing in custom-built servers (in Dropbox’s case, largely new hardware), but one could imagine a smaller scale version of that strategy using refurbished gear for a similar effect. The signal sent by Dropbox’s story is that once you reach a certain scale, owning infrastructure can yield massive economic benefits — and you don’t need to be as big as Dropbox for the math to start making sense.
• Cloud providers embracing refurbishments: In a striking twist, the very public cloud providers that ushered in the era of disposable, virtualized compute are themselves among the biggest proponents of hardware reuse. Amazon Web Services operates multiple specialized facilities to “demanufacture” and refurbish its retired servers, harvesting usable components and redeploying them in its data centers. All the major cloud platforms (AWS, Microsoft, Google) have similar circular economy programs, aiming to squeeze maximum life out of each piece of hardware in their fleets. This isn’t just for show — it significantly reduces waste and even improves their bottom line. Microsoft’s 90% reuse goal by 2025, mentioned earlier, is part of this effort. Essentially, the cloud giants are running hybrid hardware cycles internally: new servers for cutting-edge needs, refurbished ones reallocated to less demanding tasks in the cloud. If it works at that massive scale, it’s a strong validation for smaller IT shops to do the same. You might not have a “failure analysis lab” like AWS does, but you can certainly adopt the mindset that hardware doesn’t have to be one-and-done.
• Startups and SMBs finding a balance: Consider a hypothetical but increasingly common scenario — a small SaaS startup has most of its product running on a major cloud platform, but as it grows, the database costs and bandwidth fees shoot through the roof. The founding team decides to bring their primary database in-house on a couple of high-memory refurbished servers. They colocate these in a nearby data center for reliability, and connect them to their application servers in the cloud. The result? Their monthly cloud bill drops dramatically (since databases are IO-intensive and expensive in cloud), the on-prem boxes pay for themselves within months, and performance actually improves because the team tuned the hardware specifically for their workload. Yet they still use the cloud for serving web traffic across regions and for quick scaling in bursts. This kind of hybrid deployment is happening more and more, though it might not always make headlines. It’s a pragmatic approach for startups to regain some control over costs without giving up the cloud’s advantages where they matter. In essence, the startup builds a mini private cloud out of refurb servers for the core of its business, networked to the public cloud for everything else. As the company grows, it can continue to iterate on this model — maybe adding more refurbished nodes, maybe using the cloud’s global presence for new markets, constantly evaluating which option provides the better value for each aspect of their tech stack.

The takeaway from these real-world cases is that hybrid infrastructure is extremely versatile. It’s not limited to a specific size of company or industry. Whether it’s a two-person team or a Fortune 500 enterprise, mixing owned hardware (especially cost-effective refurbished units) with cloud resources can be a recipe for success. The key is to identify where the cloud truly shines for you and where it doesn’t, and then fill those gaps with your own infrastructure. As these examples show, doing so can lead to impressive cost reductions and also align with broader goals like sustainability. Little wonder, then, that hybrid strategies are gaining momentum across the board.

Future Outlook: AI, Edge, and the Next Chapter of Hybrid IT

Looking ahead, hybrid infrastructures that combine refurbished servers with cloud services seem poised to play an even bigger role. Several trends are driving this:

Artificial Intelligence and specialized computing: The rise of AI and machine learning workloads is changing infrastructure needs. Training sophisticated models (like large language models or deep neural networks) is incredibly resource-intensive — and renting dozens of GPUs in the cloud 24/7 is prohibitively expensive for many organizations. We’re already seeing AI startups and research labs invest in on-premise GPU clusters (sometimes with second-hand GPU servers) to reduce their training costs. For ongoing AI operations (model inference serving), companies may deploy trained models on local servers at offices, factories, or retail locations to minimize latency (think AI-powered video analytics on a store’s security feed, processed locally for instant insights). This is essentially a hybrid AI approach: heavy training done where it’s cheapest (maybe on-prem if you run it frequently enough, or burst to cloud if only occasional), and inference done where it’s most efficient for the business (on the edge near users, or centrally in cloud if that makes sense). Crucially, AI workflows benefit from being portable across environments. We can expect tools and platforms to evolve that make it easier to move AI workloads between your servers and the cloud. In fact, enterprises are already planning for this flexibility — they want the ability to shift AI processing seamlessly between edge devices, their own data centers, and multiple cloud providers as needs change. This kind of fluid hybrid computing will likely become standard practice for AI-heavy applications. It’s a scenario tailor-made for incorporating refurbished hardware: for example, repurposing a batch of slightly older servers as an internal AI sandbox, or using them as edge inferencing boxes deployed worldwide to complement a central cloud AI service. The cost savings and control could help more organizations leverage AI without breaking the bank.

Edge expansion and IoT: As mentioned earlier, the amount of data and computing happening at the edge (outside centralized facilities) is exploding. By 2025, an estimated three-quarters of enterprise data will be created and processed in these distributed environments. This includes everything from smart devices in our homes to sensors on industrial equipment to autonomous vehicles. Supporting this wave will require lots of local compute nodes — potentially an ideal job for refurbished mini-servers or micro data centers. Instead of deploying brand new servers in tens of thousands of 5G towers or retail stores, telecoms and businesses might use robust refurbished units (think short-depth rack servers or even converted last-gen servers) to save cost and reduce waste while rolling out edge infrastructure. These edge servers will still connect back to central cloud or core data centers, creating a massively hybrid mesh of computing. Managing it all is a challenge the industry is actively working on (through edge orchestration software, 5G MEC, etc.), but economically, the pressure will be on to do it efficiently. This environment will favor creative reuse of hardware. We may even see a secondary market boom specifically for edge-suitable refurbished gear. The sustainability angle is strong here too: deploying thousands of edge servers has an environmental impact, so using refurbished ones amplifies the eco-benefit across the fleet. In short, the future edge cloud could be partly built on yesterday’s hardware — and most users wouldn’t know the difference, but they would benefit from the improved affordability and CSR (Corporate Social Responsibility) of such choices.

Sustainability and regulation: Environmental responsibility in IT is no longer just a nice-to-have PR talking point; it’s becoming a core requirement, sometimes even mandated. Governments and industry bodies are pushing for greener tech operations. For example, data center energy efficiency standards are tightening, and there’s growing scrutiny on e-waste disposal. In this context, running a sustainable hybrid infrastructure could confer both reputational and regulatory advantages. Using refurbished equipment extends hardware lifecycles, directly reducing e-waste, which may help companies meet future compliance requirements around electronics recycling or carbon reporting. It wouldn’t be surprising if, in the near future, enterprises get credit (or even tax benefits) for practices like hardware reuse under new climate initiatives. We’re already seeing big cloud providers publicize their circular economy efforts as part of their sustainability reports. This trend could trickle down, with more companies of all sizes adopting formal “IT asset circularity” policies — meaning whenever possible, they’ll opt for reused/refurbished gear and only buy new when absolutely needed. That mindset dovetails perfectly with a hybrid approach: it encourages reusing older servers for appropriate tasks and only consuming new resources (often via cloud) for the rest. Future IT strategies might explicitly include targets for percentage of infrastructure that is refurbished or second-life. So, the next generation of hybrid cloud architects might not just ask “should this run on-prem or in cloud?” but also “can we do this with existing hardware instead of buying more?” — a subtle shift, but an important one.

Better hybrid management tools: Another factor to consider is that managing hybrid environments is likely to get easier over time. We already have technologies like Kubernetes that can deploy workloads across different environments in a unified way, and cloud providers offer services to extend their management to on-prem (AWS Outposts, Azure Arc, Google Anthos, etc.). As these tools mature, the operational penalty of hybrid (which we discussed earlier) will diminish. In an ideal scenario, a few years from now you might manage a fleet of mixed cloud instances and local servers from one dashboard, with smart automation moving workloads around based on cost, latency, or energy efficiency. If that vision comes true, it further strengthens the case for mixing in refurbished hardware where it provides an advantage, because the overhead to integrate it will be lower. Essentially, the playing field between cloud and owned hardware could level out from a management perspective, allowing cost and performance to dictate decisions more than complexity. That bodes well for any cost-saving measure like using second-hand servers. We might see a future where the hybrid approach isn’t seen as a temporary bridge or a compromise, but rather the default optimal strategy for many cases. The conversation may move beyond “cloud vs on-prem” entirely; instead, you’ll have a continuum of resources from your basement to big cloud data centers, all orchestrated together. Within that continuum, refurbished servers will have their place as much as brand-new ultra-fast silicon does.

The concept of combining refurbished servers with the cloud is, at its heart, about flexibility and resourcefulness. It challenges the notion that we must always use the newest tech or stick to one model of computing. As we head into an era of AI-driven demands and sprawling edge deployments, that flexibility will be key. Startups and enterprises alike will need to stay nimble in how they build out infrastructure, both for economic and strategic reasons. Don’t be surprised if refurbished hardware becomes a trendy option in CTO circles — it hits the sweet spot of saving money, being environmentally responsible, and adding a layer of independence from the big cloud providers’ ecosystems.

In conclusion, the hybrid infrastructure approach marries the old and the new in a way that lets each do what it does best: the cloud offers unparalleled scalability and convenience, while refurbished on-prem hardware offers solidity, predictability of cost, and control. It’s a bit like a well-conducted orchestra, where different instruments come in at just the right time to create a harmonious result. Given current trends, this orchestra will only grow more diverse and capable. So, is the future of IT a creatively hybrid one — mixing cloud services with revitalized hardware — and how will that balance shape the innovations and economics of tomorrow’s infrastructure? It’s an open question, and one that every tech decision-maker may answer a little differently, which is exactly what makes the hybrid model so powerful and fascinating.
