Serverless development is changing the traditional "build vs. buy" equation by introducing new options such as combining build with buying cloud managed services or using SaaS and building only the last mile of solution integration. This shift in approach allows organizations to focus on their unique problems and core value, rather than just running cloud infrastructure. Serverless architecture abstracts away problems associated with operating cloud infrastructure, providing time for engineers to spend on understanding issues and solving them. The typical serverless approach is still heavily slanted towards building, but buying cloud managed services can also be a viable option.
