The fact that you’re not using a single server resource makes both activities very difficult. (The good news is that tools will eventually arrive to better handle monitoring and debugging in serverless environments.) It’s often hard to make changes in the platform or switch providers without making application changes as well.
The serverless architecture is an innovative approach to deploying as well as writing an application that enables the developers to focus on code. This kind of approach can decrease time to market, system complexity and operational costs. While the third-party services like AWS Lambda are leveraged by AWS to eliminate the need to set up as well as configure virtual machines or physical servers, it also locks in the application as well as its architecture to the particular service provider.
