  • What is Cloud Computing?
  • How does it work?
what is cloud computing
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
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 computing1
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
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
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
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
Hardware Layer
  • Also know the server layer
  • Physical hardware that provides actual resources that make up the cloud.
  • Redundancy
virtualization layer
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
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
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
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
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 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
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.

Service Highlights
  • Elastic
  • Completely Controlled
  • Flexible
  • Reliable
  • Secure
  • Inexpensive
