Continuous Deployment on AWS Elastic Beanstalk with Jenkins

what is AWS Elastic Beanstalk?

• AWS Elastic Beanstalk is a fully managed platform as a service (PaaS) offered by AWS for deploying and managing applications.
• It simplifies the process of deploying applications by abstracting away the underlying infrastructure details and providing an easy-to-use interface.
• With Elastic Beanstalk, developers can focus on writing their application code while AWS takes care of the deployment, capacity provisioning, load balancing, and automatic scaling.
• It supports a variety of programming languages and frameworks, including Java, .NET, PHP, Node.js, Python, Ruby, and Go.

How to Build Serverless Web Application in AWS.

What is Serverless?

• Serverless computing is a cloud computing model where developers write and deploy code as individual functions or services without managing servers.
• The cloud provider takes care of infrastructure provisioning, scaling, and maintenance.
• Developers focus solely on writing code, and the platform automatically allocates resources and scales applications based on demand.

Why Serverless?

• serverless computing provides developers with a more streamlined and efficient development experience while delivering automatic scaling, cost savings, and improved agility.
• It is particularly beneficial for applications with varying workloads, sporadic usage patterns, and the need for rapid innovation.
