Virtualization
Virtualization is the process of creating a software-based (or virtual) representation of something rather than a physical one.
Hardware virtualization is used to distribute the computing resources (CPU, Memory, Storage and Network) of one computer into many Virtual Machines (VMs)
V Layer (Hypervisor)
Virtualization & Cloud Computing
Hardware virtualization enables low cost cloud computing
Virtualization v.s Containerization
Containers are very lightweight Virtual Machines with a stripped OS (very basic unix system) and only the Binaries and Libraries necessary to run a specific application
Is the leading software containerization platform
Most open-source projects and free apps provide docker images on the Docker Hub
You can create docker containers from docker images and run this containers on any system via docker
Application Deployment on AWS with Docker Images
Builds Docker Images When Code Is Updated on GitHub
Docker Images Can Be Stored in The Amazon Elastic Container Repository (ECR)
Amazon's Elastic Container Service (ECS) Creates and Runs Docker Containers from Docker Images
Amazon's Elastic Compute Cloud (EC2) Administers the Resources Needed for ECS
Amazon's ELB Determines if More Resources Are Needed Based On User Demand
Continuous Integration & Deployment System (CI/CD):
