Software Architect's Handbook

Taking a hybrid approach to serverless

Using a serverless architecture for a software system does not have to be an all or nothing approach. In addition to new applications fully leveraging serverless architecture, you may choose to design a part of your system with a serverless architecture and use a different architecture pattern for the other parts of your system.

For example, an organization may elect to take a hybrid approach and build some new features for an existing application in a serverless environment and use them with other architecture environments.
