Serverless computing: An evolution of Cloud computing

You don’t need to purchase servers or hire resources to look after them. You only need to monitor your applications are working harmoniously with the servers.

Scalability is described in the previous section. Since you are only paying proportionally to usage the spike in traffic is compensated by low usage. So your bills may be more or less the same.

You only need to compile your code, zip it and upload to the serverless provider. It makes your development process agile because of rapid iterations and deployment. You don’t need to write any scripts (Puppet/Chief or Start/Stop scripts). You are not spending on any system administration or on containers.

Optimizing code can increase the agility of a program. This reduces the operational cost related to your program. For example, if your usual program takes 1 second to execute an operation with the hardware server, it may now take 200 ms to perform the same operation handing you an 80% savings in costs.

Developers can write code mostly for the programs and not for the server. They can direct their efforts to innovate or improve their core programs.

When there are no servers there is no energy required to keep them running. You are saving not just in your energy bill but also the environment.

With more logic functions coming to the front end, paying when only using the server (not when they are idle) and rapidly deploying applications, you increase overall savings in costs. Rapid deployment and faster program response will lead to an improved customer experience.

With a comprehensive Serverless Feasibility Analysis, our technical and business experts work with you to develop a customized decision model for your various applications.

We offer Serverless Application Development & Support across Domains and help eliminate downtime and maximize benefits of critical applications.

Depending on the specifics of your application we offer Migration to a Serverless architecture, leading to a huge improvement in scalability and performance, and a significant decrease in cost.

As functions are stateless and persist only for a limited duration, it is recommended to write single-purpose codes for function. This limits the execution time of a function. This has a direct impact on cost. Single-purpose codes are easier to test, deploy and release. Thus, improves enterprise agility.

Designing push-based and event-driven architecture patterns where a chain of events propagates without any user input. It imparts scalability to an architecture.

Appropriate security mechanisms must be incorporated at the API Gateway layer and also at the FaaS layer. These security mechanisms include features like access controls, authentication, identify and access management, encryption and establishing trust relationship etc.

With the help of AWS services, we monitor and audit cloud-based systems or applications. To efficiently monitor the performance of systems or applications, using serverless architectures.

On-going measurement of performance bottlenecks in terms of identifying which functions are slowing down a particular service is critical to ensure optimal customer experience.
