A SaaS application serves several tenants, and each tenant should be isolated from one another. Depending on where and how you want to deploy, you may choose one or more types of isolation for your application.

Building SaaS is hard, costly and time-consuming. I have discussed the challenges in building and operating your SaaS. To learn more, please see here.

A typical startup journey looks like this: you have an idea, you validate the market, you build your initial MVP, you raise some capital. After raising the initial capital or in some cases just before, you are looking to monetize by finding a product-market fit.

Now, you can spend the next few years and use the capital on building your SaaS control plane, or you can focus on your application to build core differentiation or competitive moat and find the product-market fit to generate revenue. Doing one of them is extremely hard, trying to do both will also add significant risk to the success of your business and long-term success.

Kubernetes (K8s) Operators serve as effective tools for automating certain aspects of the control plane. In fact, if you already possess an operator and are considering building your end-to-end SaaS solution, please refer to this page.

However, it's important to recognize that having a K8s operator represents a first step towards building SaaS:

We think that Terraform is an excellent IaC tool if you want to setup your cloud infrastructure once. However, when it comes to SaaS, we feel that it falls short on many grounds.

Time and time again, we observe organizations grappling with the right design, consequently entangled in perpetual operations. Initially, with 5 or 10 customers, everything seems promising, but as you scale, the cracks start to appear from every direction.

In the rapidly evolving landscape of Software as a Service (SaaS), navigating the path to success requires foresight, strategic planning, and an acute awareness of common pitfalls. Embarking on the journey of Software as a Service (SaaS) requires careful planning to avoid common mistakes. It's not just about setting up billing and provisioning systems.

Developing software as a service (SaaS) in today's cloud environment can be compared to creating an application for an operating system (OS). Just as developers don't concern themselves with the intricacies of CPU scheduling or memory management when writing applications for Windows or Linux, similar abstractions are needed in the cloud.

Innovation is the heartbeat of the technology industry, a relentless pursuit to deliver greater value and meet evolving customer needs.

In information technology, hardware innovations paved the way, providing the computational power needed for software development. However, the coupling of hardware and software limited customization, time to distribute, cost of delivery, and customer experience. With the introduction of the Operating System (OS), software became independent of hardware. This not only tackled distribution challenges but also fueled innovation in the software industry, giving rise to various applications like Oracle databases, the Microsoft Office Suite, Adobe Photoshop, and SAP ERP.

As we contemplated building the SaaS platform, we divided the requirements into 5 packages. If you are building a SaaS from scratch, you will likely need all the layers.

We also understand that some of you may have already started but are actively looking to accelerate your SaaS journey and scale with your current team better. Hence, we have divided the platform into 5 packages to make it easy to integrate and enable/disable specific pieces:

I was among the authors at AWS who pioneered the first SaaS control plane back in 2009, laying the groundwork for many SaaS offerings both within and beyond AWS. Crafting the SaaS control plane, we delved deep into fundamental questions:
