AWS VPC

Amazon Virtual Private Cloud (Amazon VPC) lets you provision a logically isolated section of the AWS Cloud where you can launch AWS resources in a virtual network that you define. You have complete control over your virtual networking environment, including selection of your own IP address range, creation of subnets, and configuration of route tables and network gateways.

You can use both IPv4 and IPv6 in your VPC for secure and easy access to resources and applications.

Subnet

Subnet is “part of the network”, in other words, part of entire availability zone. …


What is Amazon EFS ?

Amazon Elastic File System (Amazon EFS) provides a simple, scalable, fully managed elastic NFS file system for use with AWS Cloud services and on-premises resources. It is built to scale on demand to petabytes without disrupting applications, growing and shrinking automatically as you add and remove files, eliminating the need to provision and manage capacity to accommodate growth.

Task Overview

Perform the task-1 using EFS instead of EBS service on the AWS as,

Jenkins

Jenkins is an open-source continuous integration and delivery system designed to ensure build and deploy automation. It is well-suited to be installed in the cloud to run self-hosted pipelines.

It helps automate the parts of software development related to building, testing, and deploying, facilitating continuous integration and continuous delivery. It is a server-based system that runs in servlet containers such as Apache Tom

Jenkins Cluster

Jenkins supports clustering via master-slave mode. A build process can be delegated to several slave (worker) nodes. This allows serving multiple projects in a single Jenkins cluster setup.

There are two types of Jenkins Slave

  1. Static
  2. Dynamic
