Serverless computing is derived from the concept of deploying code and launching the application to work in real-time without a defined physical server or a VM in place.

The concept became a reality with cloud computing models developed by Cloud’s big players like AWS and Azure. With serverless computing, the developers focus on writing infrastructure as code for their application to communicate with the underlying resources, services and functions in place. The processes, operating systems and other infrastructural components are not considered to launch and run the application. The underlying compute and storage resources of the application scales ups and down automatically without human intervention. It helps developers focus on programming and building the application and not worrying about infrastructural concerns to make it work. It points toward a specific application logic, where the programming architecture is executed in an environment where procedures, operating systems, working frameworks, servers or virtual machines are absent. It merits specifying that such a domain is really running on the highest point of an operating system and employs physical servers or virtual machines, yet the duty regarding provisioning and dealing with the entire infrastructure lies with the service provider. There are multiple benefits and drawbacks to serverless computing.

Pros of Serverless Computing

Improved Allocation of Resources – If server management isn’t gobbling up your time, you can concentrate on enhancing and adding more to the experience of your clients. Engineers can breathe life into new thoughts and have sufficient time to include more features to your product.

Cost Efficient – Owning and keeping up your own servers aren’t shoddy suggestions. It includes procurement of equipment, acquiring software, setting up the server and after that managing it. There are different overheads too including power, cooling, and the care staff. Going serverless means you get rid of everything that costs you financial expenses.

Upgraded Latency – Building your own server farm means each client accesses information from your area. In the event that your clients are remotely located, they will face latency issues which will cause delay in load times. Serverless engineering disposes of the issue as the service has access points close to the clients.

Enhanced Scalability – Great software engineers consider scalability when thinking about backend deployment. On the off chance that your application neglects to deal with peak activity, it is anything but a decent reflection on the application and your business. Serverless design enables you to scale evenly giving you access to as much computing power as you need.

Fast Execution – Without fretting over the server side of things, software engineers can’t just code applications rapidly but are also in a situation to deploy them in the blink of an eye as well. Designers can make new applications and dispatch them in a matter of days as opposed to sitting tight for months.

Cons of Serverless Computing

Vendor Dependability – Your entire operation is dependent on the quality of service provided by the vendor. Although the players in the serverless architecture industry have massive and well-earned reputation, if you are not happy with the solution; you have limited choices.

Cross Vendor Compatibility – If you are not fine with your server host you can change it easily or build your own. However, it’s not that easy in the new serverless world. For example, if you are using Azure, it would be a complex process to port your application to Lambda.

Learning Curve – Function as a Service (FaaS) hasn’t gone mainstream yet and that’s why despite comprehensive documentation and resources, you have to go through an uphill learning curve.
