Benefits of the AWS Cloud

• Trade fixed expense for variable expense
• Benefit from massive economies of scale
• Stop guessing capacity
• Increase speed and agility
• Stop spending money to run and maintain data centers
• Go global in minutes

The AWS Shared Responsibility Model

AWS Regions are physical locations around the world that contain groups of data centers. These groups of data centers are called Availability Zones. Each AWS Region consists of a minimum of three physically separate Availability Zones within a geographic area. https://aws.amazon.com/compliance/shared-responsibility-model/

An Availability Zone consists of one or more data centers with redundant power, networking, and connectivity. Regions and Availability Zones are designed to provide low-latency, fault-tolerant access to services for users within a given area.

The AWS Shared Responsibility Model

The AWS Shared Responsibility Model is a concept designed to help AWS and customers work together to create a secure, functional cloud environment Applying Cloud Concepts to Real Life Use Cases

Module 2: Compute in the Cloud

Introduction to Amazon EC2

• Amazon Elastic Compute Cloud (Amazon EC2)
• Amazon Machine Image (AMI), which defines the operating system and might include additional software
• instance type, which determines the underlying hardware resources, such as CPU, memory, and network performance.

Scalability is about a system’s potential to grow over time, whereas elasticity is about the dynamic, on-demand adjustment of resources.
