Timeframe: 3 Years, End of 2026
Category: Business
The pandemic ushered in a historic wave of spending on IaaS and SaaS as companies scrambled to adapt to remote work, digital transformation, and operational continuity. Cloud infrastructure spending soared 35% in 2020, hitting $130 billion, with SaaS applications like Zoom and Microsoft Teams becoming household names, growing their user bases by hundreds of millions in a matter of months【13†source】【14†source】. AWS and Microsoft Azure capitalized on this trend, reporting 32% and 50% growth, respectively【20†source】.
However, after the all-night party of “spend-at-all-costs” on cloud services, businesses are waking up to what many now call the “SaaS hangover.” The headache comes in the form of bloated invoices, growing complexity, and a creeping realization that renting cloud infrastructure and software may not be sustainable in the long run. CFOs and CIOs, once dazzled by the promise of flexibility and scalability, are beginning to sober up and scrutinize the true cost of these ‘as-a-service’ models.
With profit margins under pressure, these leaders are increasingly looking for opportunities to trim the fat—and what better place to start than the massive cloud bills that exploded during the pandemic? IaaS, in particular, is a prime target for cost-cutting. The appeal of on-demand infrastructure is undeniable, but when organizations take a closer look, the monthly AWS or Azure invoice can be staggering, especially for businesses running dozens of VMs, databases, and other mission-critical services.
Imagine a mid-sized company running 20 VMs on AWS for various business applications. Their cloud bill might easily exceed $15,000 a month, adding up to $180,000 annually. Now, what if they opted for self-hosting? By investing in high-quality servers and network infrastructure, this same company could potentially lower its annual infrastructure costs to around $50,000. That’s a one-time hardware purchase with predictable operational expenses, versus an ever-increasing monthly cloud bill that fluctuates with usage spikes and data transfer costs.
Self-hosting also gives businesses complete control over their infrastructure and data, not to mention the added benefit of security—data stays within the company’s own perimeter, reducing exposure to third-party vulnerabilities. Performance can be optimized for specific workloads, and any excess capacity is theirs to utilize without incurring additional fees.
For companies eager to recreate the flexibility and ease of cloud environments, platforms like OpenStack or VMware vSphere provide robust alternatives. OpenStack, for instance, enables businesses to deploy their own private cloud, offering an AWS-like console experience on their own hardware. By managing VMs, storage, and networking through a user-friendly interface, companies can essentially run their own cloud, sans the high costs associated with renting infrastructure from a public provider. Other tools like Kubernetes for container orchestration and Terraform for infrastructure-as-code make it easier than ever to manage on-premise resources in a scalable, flexible way.
In a post-pandemic world, businesses are beginning to realize that they can have the best of both worlds: the control and cost-efficiency of self-hosting, paired with the flexibility and automation typically associated with cloud providers. This shift could very well represent the next phase of digital evolution, as companies strategically reduce their reliance on IaaS giants in favor of owning their tech stack.
