What is Serverless Technology?

Serverless technology is a cloud computing execution model which empowers you to build and run applications and services without managing servers. Presently, serverless technology refers to two major technology stacks: services that depend on third-party services (knows as Backend as a Service or “BaaS”) or on custom code that’s run in ephemeral containers (Function as a Service or “FaaS”).

Serverless technology doesn’t necessitate you to provision, scale, or deal with servers. You can build them for nearly any type of application either as FaaS or BaaS, and whatever the infrastructure needed for the application will be automatically managed for you.

Building serverless applications means that your developers can allocate more time on building their core product instead of worrying about infrastructure management. This reduced burden empowers developers to build products which are highly efficient and scalable.

How did we Arrive at Serverless?

About 10 years ago, monoliths were a lot of hard work, the networks & CPUs were too slow and the messaging protocols were heavyweight. When monoliths split up into microservices, CPUs and networks got a lot faster which enabled much more efficient protocols.

These are an extremely efficient form of a fairly complex looking network with a lot of messages flowing backward and forwards. Over the time, this environment became more and more standardized form of application development.

However, to provide higher scalability and availability, these services split-up into nano-services called functions which are being offered as off-the-shelf services. Functions are not running until there’s something work for them to do. You get a request coming in from the gateway and it gets routed through a few other functions and finds its way to a particular set of services.

By doing this, it’s incredibly efficient in terms of runtime because whenever the system is idle it shuts down and it costs nothing to run! Everything is always hundred percent utilized and it turns out these functions are very short and easy to write.

We’ve seen monoliths and then microservices taking over 5 years ago and now we see functions picking up which is paving a new paradigm for building business logic.
