Serverless Computing

Benefits of Serverless Computing

What is Serverless Computing?

Serverless computing also mentioned as Function-as-a-Service (FaaS) is replacing traditional cloud-based or server-centric infrastructure.
It relieves developers and architectures the worry of provisioning, purchasing and managing backend servers. Initially, anyone who wanted to develop an internet application had to possess hardware to run a server. It takes tons of your time and capital to develop.
Serverless allows developers to get backend services where all the server space and infrastructure concerns are overseen by the seller . It helps you perform common functions like autoscaling during a REST API.

This model offers the subsequent key capabilities:

  • Running code residing as functions independent of the user having to explicitly provide the infrastructure or manage it
  • Using an API which will associate a function with events which will act as triggers for its execution.
  • Automatically provisioning, scaling a runtime environment needed to execute a function.
  • Offering additional platform capabilities like monitoring and logging for service assurance.

Main advantages of Serverless Architecture:

Enhanced scalability

Everyone wants their app to be great. If it becomes a hit, will it’s ready to handle the traffic? Provisioning infrastructure becomes a major concern. Serverless approach is right and versatile for scaling applications.

The vendor handles all of your functions and runs them separately. This gives you an opportunity to scale them automatically and endlessly. With serverless, you don’t have to purchase an approximated number of resources, you can be as flexible as manageable.

Lower cost

Serverless approach saves time and resources. It’s a pay as you go computing meaning you’re charged the memory and time allocated to your code. Idle time is not billed. Cost benefits include lack of OS costs including installation, dependencies, support, maintenance and patching. This saves cost in a huge manner.

Improved Geolocation

The ability of an app to scale depends on network latency, its number of users and the users’ location. We live in a global village and many apps have global audiences. This can create latencies which can demean experiences. Serverless providers have points of presence near every user aiding the apps to perform optimally for everyone.

Decreased time to market

Serverless approach has enabled developers to develop apps in hours and days as opposed to weeks and months. Many new apps depend on third-party APIs. It is event-driven. Architects can run, test and deploy their code without relying on ops to test their code.


Users don’t specialise in the infrastructure of the app but its features and experiences. Serverless allows the developers to focus resources on elements which will make the user happy. Serverless helps solve many issues.

Serverless approach may be a good way for consuming the resources of the cloud. FaaS providers focus on their serverless offerings. This approach can reduce time to plug, operational costs and system complexity.

This technology allows businesses to specialise in high value and level applications rather than worrying about configuration. The development of serverless technology has allowed innovative skills and ideas to shine. It guarantees reliability, performance, scalability, security and price. You don’t need to worry about service availability.
