You can create a web app. And, you will no longer need to secure and manage a server.
Seems like a dream come true for a front-end developer?
Well, hold your horses! A genuinely serverless reality is far away. But, with the advent of serverless computing assistance like AWS Lambda, Google Cloud Functions, and Microsoft Azure, you get to wash your hands off servers, at least in the technical sense.
Serverless Architecture- Defined and Demystified
The concept is simple.
You can utilise cloud services, like the ones mentioned above, to perform functions. They are flexible, cost-effective, easy to scale. And, they let you, i.e. the developer, focus on the business logic. While you do that, the cloud service you’re paying takes care of the infrastructure, upgrades, and security.
The appeal of serverless hosting is clear.
You pay according to the time your code takes to run. Your functions may be written in different languages. They will be instantiated when needed and run on the infrastructure. You can efficiently manage the code, its composition, the debugging process, and the serverless functions’ lifecycle.
The outlook: With serverless services, infrastructure and scalability won’t be your problems anymore; they’d be the headache of a service provider while you get to focus on the business logic.
Benefits Serverless Architecture Has to Offer to You
You pay per function.
Developer Avner Sorek moved his Express.JS application to Lambda+APIG within a day. From paying $44.95 per month to AWS Elastic Beanstalk, he came down to paying $6.12 per month.
Adam Pash, Director of Engineering, Postlight, carried his company projects to a serverless framework and cut the costs from $10,000 to $370.
Infrastructure issues are no longer your problems. Eventually, the releases will get easier to push with only the code to focus on.
Especially for big enterprises, this is a magic solution. They can leave the dirty work, like merging the old API and the new components or conducting backward compatibility testing, behind. Serverless computing lets them split the code into functions which are way easier to manage.
Scaling is both, hard at first and costly when achieved. Serverless hosting makes it more accessible as well as pocket-friendly.
For instance, AWS Lambda offers to dynamically scale the capacity as needed by analysing the increase in traffic.
So, Why Isn’t the Dev Community Fighting to Death over Serverless Architecture?
AWS Lambda came up with a new service, called as the Step Functions that lets functions last indefinitely.
Before that, functions needed to be stateless, event-driven, idempotent services that had to be driven by a state machine. Why? Because providers were, and many still are, placing execution time on functions. And, if your function calls a lot of other services or has many input processes, the execution limit will backfire.
Now, this is one of the reasons why the Dev community is just coming to terms with going serverless.
Of course, there are other factors. Like, the tech has only recently become cost-effective. An improved range of service providers entered the market not long ago. And the competitive advantage to the buyer is becoming visible now. Given some time, you can expect serverless computing to go mainstream.
