Lift and shift is the process of migrating a workload from on premise to AWS with little or no modification. An easier and less costly way to migrate into the cloud is to take the existing workload the way it is currently and run it on cloud resources. This is commonly referred to as the “Lift and shift ” approach or "rehosting". We will take a closer look at the lift and shift cloud migration approach, and explore the benefits. In this first part of a three part series we'll consider how we can significantly improve a lift and shift application in regard to performance. We'll show that without modifying the application we can integrate services and features that will make a lift and shift faster.

Network routing is the process of enabling computers to transfer data over networks, including the internet.

Installing the PostgreSQL on EC2 instance is similar to installing PostgreSQL on any other server whether it is on premise or in the cloud, With an EC2instance you can configure CPU, memory, storage, and networking capacity.

Today we will look at how to configure ANSIBLE Client Nodes in order for the Control Node to automate tasks.

This will involve setting up SSH Passwordless login.

Ansible is a configuration management and orchestration tool. It works as an IT automation engine. Ansible can be run directly from the command line without setting up any configuration files. You only need to install Ansible on the control server or node

Today we will look at how to look at an ANSIBLE Playbook.

A Playbook is like an instruction manual which tells the Ansible Control Node what to do when it connects to each Client Node or machine. Playbooks are written in YAML.

Roles are ways of automatically loading certain vars_files, tasks, and handlers based on a known file structure. Grouping content by roles also allows easy sharing of roles with other users.​

Docker is a tool that allows developers, sys-admins etc. to easily deploy their applications in a sandbox (containers) to run on the host operating system i.e. Linux.

The key benefit of Docker is that it allows users to package an application with all of its dependencies into a standardized unit for software development. Unlike virtual machines, containers do not have high overhead and hence enable more efficient usage of the underlying system and resources.

A container is a standard unit of software that packages up code and all its dependencies so the application runs quickly and reliably from one computing environment to another.

In this lesson you will learn how to push an image to Docker hub.

Kubernetes is Google's open source system for managing Linux containers across private, public and hybrid cloud environments. Kubernetes automates the deployment, scaling, maintenance, scheduling and operation of multiple application containers across clusters of nodes.

Jenkins is an open-source continuous integration software tool written in the Java programming language for testing and reporting on isolated changes in a larger code base in real time. The software enables developers to find and solve defects in a code base rapidly and to automate testing of their builds.
