Serverless computing is a cloud application development and execution model that allows developers to build and run code without managing servers and paying for idle cloud infrastructure. Not only this, but serverless comes with various advantages for developers, such as quick deployments, auto-provisioning of resources, and decreased latency.

However, developers can extend the capabilities of serverless applications by using external APIs. How? Typically, serverless applications run as a single code block and use libraries to avoid reinventing the wheel. However, this creates a technology stack lock-in, where developers can only use libraries available in the same programming language as their serverless application. APIs allow developers to bypass this limitation and connect with remote services that provide capabilities. This flexibility allows them to create more complex serverless applications.

External APIs can even help developers in rapid development, cost efficiency, and achieving vertical scalability.
