Introduction

Let's imagine that you are developing a complex application with many functions in one cloud provider. It may not be feasible to move to another cloud provider, even if the new one is cheaper, faster, or more secure. This situation of vendor dependency is known as vendor lock-in in the industry, and it is a very critical decision factor in the long run. Fortunately, serverless frameworks are a simple and efficient solution to vendor lock-in.

In the previous chapter, all three major cloud providers and their serverless products were discussed. These products were compared based on their programming language support, trigger capabilities, and cost structure. However, there is still one unseen critical difference between all three products: operations. Creating functions, deploying them to cloud providers, and their management are all different for each cloud provider. In other words, you cannot use the same function in AWS Lambda, Google Cloud Functions, and Azure...
