The New Age of Serverless Apps

The New Age of Serverless Apps

Introduction

Developers has been developing applications of different kinds including web, mobile and cloud. Many developers use to store the data of their applications on physical hard drives and nowadays on cloud. For that, they had to manage servers either on-premises or remote. They had to take care of its maintenance which became hectic as time passes and data comes at bottleneck. Cost is the major factor that gets increased when we enhance the capabilities of the server in terms of its space, networking, cabling, cooling or virtual machines etc. 

Serverless Architecture

Serverless architecture, as name suggests has brought relief for developers as they no longer had to look after servers on their own. They will no longer have to carry the burden of heavy data loads and deployment over the server. There has been now a shift of the deployment of applications from cloud to serverless architecture. One thing that must be understood, with serverless architecture, it does not mean that servers will no longer be used in any way, that is totally wrong in fact, the cloud owners or providers will manage the servers. It can be said as, serverless architecture is software-as-a-service for developers.

Applications on Serverless Architecture

Serverless architecture gives developer the opportunity to deploy their applications by just providing the code without thinking about the servers, OS computation etc. For example, Amazon Lambda executes applications when we provide code and do trigger some events. It itself handles the cloud or back-end of that application. There is no need to download or install additional software on your computer. 

Why Serverless Architecture are the future of apps?

1. It will benefit the user for its fast deployment i.e. no server down issues anymore.
2. It will only trigger application when there is an event triggered.
3. No need to manage extra resources or hardware for the app to run.
4. Cost is reduced as no hardware is involved additionally.

From web app to mobile app, serverless architecture will now be able to handle applications for IoT, make dashboards, hosting of back-end for mobile apps and event Video-on-Demand (VoD) services.

This actually depicts the future of serverless applications as it has widens the category of application to be built on it.
