Serverless computing is an increasingly popular technology model that is making the lives of ops teams and developers better. There's no need for a company to know about the hardware or OS their code runs with serverless computing. Instead, it all is taken care of by a service provider. But how is this possible?
Serverless computing is a cloud-based model in which a cloud provider dynamically allocates only the resources and storage needed to execute a particular piece of code. It means that you will not be paying for any unused space, and you can code without worrying about the underlying infrastructure requirements.
How Does Serverless Computing Compare to Other Technologies?
Historically, physical hardware was required to run a server. Then the cloud was released - which consisted of renting "remote" spaces to fulfill server requirements. However, companies often find themselves over-purchasing this space that would only be sold as fixed units. This technological void increased the need for serverless computing. Essentially, it allows a developer to only pay for the storage they are using without worrying about servers or other internal infrastructure requirements.
Do not let the name fool you; the term "serverless" describes the customers' experience of servers; as mentioned above, there is none on their physical premises. Furthermore, since it is a cloud execution, they might as well be invisible because the customer won't have to see, manage, or interact with them in any way.
The significant advantages of serverless computing are:
How Does Serverless Computing Compare to Other Cloud-Backend Models?
Backend-as-a-service (BaaS) is similar to serverless computing because developers only worry about writing their application code. However, serverless computing functions are event-driven, meaning each function has to be triggered by a specific event. On the other hand, BaaS is not event-driven, meaning it may require more server resources.
Platform-as-a-service (PaaS) realizes all backend management behind the scenes, simplifying the web application development. Developers essentially rent everything they need to build an application. The provider then takes care of the developing tools, infrastructure, and operating system. Although it has some similarities with serverless computing, PaaS often has a noticeable startup delay.
Infrastructure-as-a-service (IaaS) refers to a collection of computers and servers that run code and store data, including all the hardware connections between those machines. IaaS is utilized when cloud computing vendors host the infrastructure on behalf of another customer. It does anything that traditional on-premises infrastructure can do, but with more flexibility.
