Project Description

Serverless Computing – A Case Study

Overview

Serverless computing is considered a new generation of Platform-as-a-service, as in this case, the cloud service provider takes care of receiving client requests and responding to them, monitoring operations, scheduling tasks, and planning capacity handling. Thus, developers have no need to think about the server or the infrastructure issues and can entirely concentrate on writing code.

Background

One of our leading IT clients needed a much better way to implement this serverless computing system to an audio platform using AWS for Audio streaming mobile application. They wanted help with serverless applications that enables developers to incorporate the benefits of serverless computing during deployment.

Challenges

In Serverless computing, there is a limited set of influences for teams to identify problems in monitoring or debugging the architecture is a challenge.

In addition, there’s a risk that your software might be placed along with function-heavy applications on the server that may cause slow performance. Rapid development of backend APIs and with AWS DynamoDB as database will be the main challenge in serverless computing.

Centizen Solution

With hybrid mobile applications for audio streaming, computing takes place in the cloud, not on the device. All cloud-hosted computing processes for the app can be serverless, just like a serverless web application. The only major difference between a serverless web app and a serverless hybrid mobile app is the native wrapper on the frontend.

Centizen developed a serverless web application, where the app’s code is hosted by a serverless vendor who handles backend management. The application is divided up into modules called functions that do not appear wholly on any specific servers. Each function responds to trigger events, and the vendor’s infrastructure starts up new instances of functions as needed.

Outcomes/ Business Values

Reduced cloud costs

The cost will be nothing when your application doesn’t run. Developers pay only for the time when their application executes a user’s functions in response to specific events or requests.

Elastic scalability & Availability

A serverless architecture has the ability to scale up and down according to application workload. Developers no longer need to purchase additional infrastructure for handling unexpected growth.

Agile-friendly development

Allows developers to concentrate on application code rather than infrastructure maintenance.

Lower TCO

The cloud provider manages the infrastructure, platform, maintenance, and scalability. You are only charged for the time your function is running.
