One of the most important difficulties with improving serverless applications is to operate and test the application provincially. Because serverless applications are hosted on the cloud, it makes it very slow to debug, test and iteratively develop code. Although all cloud providers and the Serverless Framework allows requesting one function at a time provincially, the developer wishes to run the full application sectionally on their machine.

The Serverless Emulator emulates different cloud provider FaaS offerings on your local machine in an offline-focused manner. It provides that missing piece of tooling that makes application development with serverless so productive and exciting. It enables deploying and invoking serverless functions without the requirement of setting up and deploying your serverless application to the cloud provider.

Developers will often wonder whether more and more parts of their service could be moved into the cloud. Databases, file storage, and even servers are slowly transitioning to the cloud, with servers being run in virtual containers as opposed to being hosted on a dedicated machine. Complexity with uploading, deploying and versioning now become cloud-related. This, along with several current limitations of the FaaS model, has often positioned serverless technology as being best suited towards complementing a dedicated server.
