What is Serverless? 

Serverless is a widely relied upon cloud-native development model that enables developers to create and run applications without server management.

Serverless does utilize servers, but these servers are not directly involved in application development. The tasks related to handling the maintenance, provisioning, and scaling of infrastructure do not have to be handled by developers. Application developers can easily enclose their code into containers for deployment purposes.

After deployment, serverless applications can automatically scale up and down resources based on demand. Serverless backends offered by public cloud providers generally work through an event-based execution model on an on-demand basis. Hence, developers do not have to pay when a serverless function is not being used.

Serverless has a fundamental difference compared to other cloud computing models, as a cloud service provider is tasked with cloud infrastructure management and application scaling. Containers contain the serverless applications that are launched automatically when the demand arises.

Users of an IaaS computing model are required to purchase capacity units in advance and pay depending on components necessary for running applications. Scaling up and down for this model is the user’s responsibility. Users of an IaaS backend have to keep a cloud infrastructure active despite the application not being used.

In comparison, serverless architecture is launched only when the requirement arises. An event directs app code to run, prompting the cloud service provider to allocate resources dynamically. Users stop paying when code execution is complete. Using a serverless backend also helps to reduce the burden of performing minor and repetitive tasks for management.

What are the benefits of serverless? 

Here are the main benefits of using a serverless architecture:

  • Faster Time to market

Due to the absence of operational demands, developers can manage to release applications faster. It also enables them to receive faster feedback and generate swifter iterations. 

  • Costs are lowered

The billing model for serverless backends is pay-as-you-go. As a result, users do not pay for overprovisioning, and their resource usage is also optimized.

  • Peak stability 

Serverless backends have technology that can scale from no to high demand automatically. It enables users to measure up to changing customer needs without delay. 

  • Easier to build applications

Serverless apps contain built-in integrations, enabling users to focus on creating an application rather than constantly tweaking it. 

Serverless Groups

Serverless is usually divided into two different categories.

BaaS – Backend as a Service

Backend as a service (BaaS) refers to a cloud computing model that functions as a platform offering developers the ways to establish connections between their applications and cloud services. It utilizes software developers’ kits (SDK) and application programming interfaces (API) for connecting applications to the cloud. In comparison to other cloud service models, BaaS is a newer option. BaaS is also known as MbaaS or mobile backend as a service. 

FaaS – Function as a Service

FaaS (Function as a Service) refers to one of the newest cloud models, preferred by many developers today. It is in the category of (Cloud Computing Services), offering users the capabilities to develop, run, and manage applications. Users can build apps without having to maintain sophisticated infrastructure and launch without hassle. Using FaaS helps users to experience truly serverless development. It is used widely for building microservices.
