Serverless computing is a new concept that changes the way developers build and deliver software systems. Serverless data processing and Function-as-a-Service will play an important role in defining the next corporate IT era. Why? Let’s find out!
min3 minAccording to a survey conducted by the world’s leading provider of open source solutions Red Hat group, 36% of its customers already use serverless applications in production systems or in internal experiments, and another 28 percent currently plans to implement serverless.
What serverless is?
Serverless computing is a hot technology, though with a bad and misleading name. First of all, because the services and applications that use it actually work on servers. The creators of this term were rather to emphasize that users in no way manage the servers on which their code runs.
Currently, when creating mobile solutions, we can use our servers and the API, but it will not necessarily be the most cost-effective solution. Often a much better solution will be to use ready-made components provided by companies such as Microsoft, Google or Amazon. That is why solutions in the BaaS type cloud and newer FaaS have been created.
Thanks to the use of cloud solutions, we lose the whole part of the work associated with maintaining the machines. Let’s briefly explain both, BaaS & FaaS.
BaaS – Backend as a Service
Thanks to the use of the cloud, we can use ready-made components such as login mechanisms, a scalable database, cache and so on. This allows the developer to accelerate software development and simplify API creation. Instead of coding the entire backend developer will use a BaaS to create the APIs and link it to the applications.
FaaS – Function as a Service
It’s a serverless product that hosts a piece of business logic (with a usually small footprint like resizing an image or sending an email). It provides the ability to deploy what is essentially a single function, or part of an application. FaaS is very well suited to build Event-Driven architecture.
4 Advantages of Serverless Technology
#1 Shorter time to market and faster releases
You can not only deploy apps faster but can easily roll out updates and ensure they get reflected in the program faster than ever before. Less time spent on operations equals fewer people needed for operations. As your teams and products become increasingly geared toward lean and agile processes, you want to continually try new things and rapidly update your existing systems right?
#2 Lower costs for both operations and development
Serverless technology allows you to pay a fraction of the price per request. Hence, if you’re a startup, you can build an MVP nearly for free and ease into the market without dealing with huge bills for minimum traffic. Traditional servers force you to have a fixed cost. Whether you have or haven’t used it. With serverless, your costs vary on your usage.
#3 Cheaper scaling
We all want to create the next Instagram, but would you risk provisioning infrastructure just in case? With serverless, you don’t have to make a choice, but you’ll still be ready for any volume of growth.
#4 Different programming languages
These are just a few of the many benefits of using serverless technology. Like any technology, it has both pros and cons, but there’s a reason why more and more businesses go for it and leave competitors behind.
