Going serverless is defined as designing and operating applications without the need for a deep understanding of the underlying infrastructure. But is going serverless beneficial? This article outlines why going serverless should be your preferred option. But first, what is serverless computing?
Serverless computing is an execution approach where cloud providers offload their own server resources for others to use. They do so by dynamically allocating resources and billing according to the resources used to run applications.
Below are four reasons why you should consider going serverless:
When you go serverless, you will only be charged for the time while the tasks are performed. As a result, you’ll never have to pay for wasted capacity again.
It’s More Secure
Security in serverless technology has advanced significantly in recent years. If you look under the hood, serverless is not quite ‘server-less’. What this term really means is that the burden of maintaining, provisioning and securing the servers falls on the cloud provider. Leading providers, such as AWS, are thorough, with dedicated teams ensuring that their servers are protected and patched.
If that’s not enough, function-specific security can be deployed at the application level, ensuring that each function has unique access points, access levels, and system-wide permissions. These fine-tunings guarantee that specified functions do not mistakenly touch or call other platform components.
Serverless applications and functions can scale automatically. Serverless functions are implemented as requested and automatically adjust themselves to the volume of requests. Because cloud service providers operate under robust SLAs, surges in requests have no impact on application performance. That’s one less thing to worry about.
It Enables Rapid Iterations
There is zero need to upload code to servers when adopting a serverless infrastructure. There’s also no need for any backend configuration to release a working version of an application. Developers can rapidly deploy code and launch new products to the market.
The Bottom Line
Ultimately, serverless computing supports development teams across the globe. It allows developers to remain focused on writing code and understanding where to run their code, rather than fighting with infrastructure. Additionally, serverless computing has several advantages over traditional cloud-based or server-centric systems, such as being more cost-effective, secure, scalable, and iterative.
