Let’s Architect! Understanding the build versus buy dilemma

Vendor lock in happens when you commit to a specific technology and then don’t have the freedom to maintain full control of your applications. Even if you want to switch to another vendor, it’s not easy because of the financial investment, effort, and time needed to do so.

In the cloud computing, technology changes quickly, and vendor lock in can impact your business objectives. In this edition of Let’s Architect!, we show you how to avoid the risks of vendor lock in and examine when you should build or buy new software.

Buy vs. Build Revisited: 3 Traps to Avoid

In this blog post, Gregor Hohpe shares some tips on how to avoid risks of vendor lock in. He advises to “build the software that differentiates your business and buy all else” and shows you how opportunity cost, an economic concept, plays major role in whether to build or buy software.

Time to Rethink Build vs Buy

Which is the right option for your business: build or buy? Customers often ask this question. The answer is: it depends.

Moving to the cloud does not necessarily mean you are locked in to a cloud provider. Most cloud platforms offer you a pay as-you-go model with the flexibility to choose from a wide range of services and solutions such as serverless, DevOps, etc. However, having advanced and scalable technology products powering your business can help differentiate your core product. And, it can help you innovate faster and increase speed and agility. This blog post will help you choose the right path for you based on your business objectives.
