What are the key characteristics?
How many layers and their functionality?
Amazon EC2

3. 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.

4. 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

5. 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

6. 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

7. 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

8. 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

9. Hardware Layer Also know the server layer
Physical hardware that provides actual resources that make up the cloud.
Redundancy

10. Virtualization Layer Most scalable and flexible layer
Various operating systems being installed as virtual machines
Virtual machines can be created and deleted at will

11. Infrastructure as a service (IaaS)
Provides companies with, computing resources including
Servers
Networking
Storage
Data center space
All on a pay-per-use basis

12. 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.

13. 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.

14. Client Layer
User interface to which cloud computing services are delivered.
Client layer hardware can include
personal computers
web browsers
mobile devices

15. 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.

16. 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.

Secure
Inexpensive
