Amazon EC2

What is cloud computing?

Webster:"the practice of storing regularly used computer data on multiple servers that can be accessed through the Internet“.

An innovative way of conducting every day business and entertainment.

Types of Cloud Computing

Web-based cloud services

services let you use certain web service functionality, rather than using fully developed applications

SaaS (Software as a Service)

providing a given application to various users

Platform as a Service

deviation of SaaS to you run your personal applications that you execute in the cloud

Types of Cloud Computing

Utility cloud services

virtual storage and server options (i.e iCloud or DropBox)

Managed services

cloud provider utilizes an application rather than end-users

Service commerce

provides a hub of services which the end-user can interact with

How does it works?

Nothing is local

Data is uploaded

Stored in data centers or data farms

Data is copied several times over

Very difficult to lose

What are the key characteristics?

Dynamic computing infrastructure IT service-centric approach Self-service based usage model Minimally or self-managed platform Consumption-based billing

How many layers and their functionalities?

The Hardware Layer The Virtualization Layer Infrastructure as a Service (IaaS) Platform as a Service (PaaS) Software as a Service (SaaS) The Client Layer

Hardware Layer

Also know the server layer

Physical hardware that provides actual resources that make up the cloud.

Redundancy

Virtualization Layer

Most scalable and flexible layer

Various operating systems being installed as virtual machines

Virtual machines can be created and deleted at will

Infrastructure as a service (IaaS)

Provides companies with, computing resources including

Servers Networking Storage Data center space

All on a pay-per-use basis

Platform as a service (PaaS)

Provides a cloud-based environment with everything required to support the complete lifecycle of building and delivering cloud applications

Customers do not manage their virtual machines.

Software as a service (SaaS)

Run on distant computers “in the cloud” that are owned and operated by others

Services at the software level consist of complete applications that do not require development.

Client Layer

User interface to which cloud computing services are delivered.

Client layer hardware can include personal computers web browsers mobile devices

Amazon EC2

Amazon Elastic Compute Cloud is a web service that provides resizable compute capacity in the cloud.

It is designed to make web-scale computing easier for developers.

To use Amazon EC2

Select a pre-configured Amazon Machine Image or create a custom AMI.

Configure security and network access on your Amazon EC2 instance.

Choose which instance type you want, then start, terminate, and monitor.

Determine whether you want to run in multiple locations.

Pay only for the resources that you consume.
