It wasn’t until relatively recently that physical servers were the backbone of every data centre. While on-premise servers have by no means disappeared, more and more infrastructure components are finding their way into the cloud every year and hype around serverless computing is growing. But what is it?
Serverless computing is a form of software architecture whereby the responsibility for time and resource-intensive infrastructure management processes such as patching, securing and scaling servers is outsourced to cloud providers. This means resources spent on building, scaling and securing can now be more profitably invested in the applications themselves. Though the name suggests otherwise, serverless computing cannot do without servers entirely – physical infrastructure is needed, but only on the cloud provider side.
The cloud provider, whether it be AWS, Google, Azure or another, is also responsible for the dynamic allocation of resources to individual applications and tasks. This brings several advantages.
Greater ability to innovate
Container orchestration and mesh management using serverless methods fundamentally change the daily business of internal company teams in infrastructure management, redefining their objectives. It means they are now the beneficiaries of an infrastructure that is optimally adjusted for them, and that they no longer have to build, scale and secure it themselves.
With the responsibility for infrastructure management in the hands of cloud providers, serverless computing frees up organisations’ time and money. They can channel resources into ensuring their applications function better, creating the opportunity to innovate faster and more easily.
Instant scalability
Serverless also promises considerable advantages in terms of scaling. A high degree of configuration preparation is not required, so it is therefore far more agile than conventional scaling based on cloud servers. For example, AWS Lambda has proven itself in the scaling of any number of short-running tasks. It doesn’t matter whether there are hundreds of events or several billion
