We all know that cloud computing has been a game changer in a number of ways either its infrastructure, services, platform or others. I’ll try to keep this simple: the phrase “serverless” doesn’t mean servers are no longer involved. It simply means that developers no longer have to think “that much” about them. Computing resources get used as services without having to manage around physical capacities or limits.
In the beginning, the meaning of serverless computing was limited to development of applications which are dependent on third-party services in the cloud. These 3rd party apps or services would manage the server-side logic and state. Beside a related term – Mobile back end as a service (MBaaS) also became common.
But now serverless architecture is defined by stateless compute containers and modeled for an event-driven solution.
It is the next generation cloud computing technology that is also popular as Function-as-a-Service (FaaS). FaaS provides a platform allowing the developers to execute code in response to events without the complexity of building and maintaining the infrastructure.
Amazon AWS offers Lambda service which is the perfect example of serverless.
In this technology we have big vendors in the Market
- Amazon WebServices
- Microsoft Azure
- Google Cloud Compute
- IBM Openwhisk
Difference between traditional cloud computing and serverless computing
In traditional cloud computing, it is compulsory for the organizations to pay a fix and recurring amount to run their website and application either they use all instances or not. as compared to in serverless computing, where we have to pay only for the services or instances you have used. No charges for downtime and idle time.
Benefits from Business Perspective
- Cost is based on execution measured in second no hours
- Introduces more agility smaller deploy able units results in faster delivery of features
- Cost of hiring infrastructure engineer goes down
Benefits from Developer Perspective
- No administration required
- Faster to get up and running
- Monitoring out of box
- Not worry about concurrent request
It goes without saying that not all applications can be implemented in the serverless way. There are limitations especially when it comes to legacy systems and using a public cloud. However, it is exciting to see Lambda and services such as the API Gateway grow in capability and evolve all the time.
I strongly believe that if used wisely, a good serverless architecture can speed up development time and help to produce a more robust product. Share your opinions by commenting below.
