Definition “ The computer industry is the only industry that is more fashion-driven than women’s fashion”

Need of Cloud Computing:

Need of Cloud Computing Think of an organization....


Problems..? Hosting of Application Cost of Servers Software Updates Hardware Management Electricity Consumption

PowerPoint Presentation:

? Solution

Cloud Computing:

Cloud Computing Internet Your computer don’t pay for hardware and maintenance The services provider pays for equipment and maintenance Servers Users

Anatomy of Cloud Computing:

Anatomy of Cloud Computing Servers Data Centre Cluster Public Private Hy brid brid

Cloud Components:

Cloud Components Internet Data Centres Distributed Servers Client Devices


Clients Mobile: Mobile devices include smart phones and PDA’s etc. Thin: Client computers without internal hard drives, servers do their work. Thick: Regular Computer with all necessary components.

Benefits of Thin Devices:

Benefits of Thin Devices Lower hardware cost Lower IT cost Security Data Security Less Power Consumption Ease of Repair and Replacement Less Noise

Data Centres & Distributed Servers:

Data Centres & Distributed Servers Data centres are the collection of servers where hosted applications are housed. Virtual Servers are in trend now a days. Distributed Servers are geographically separated routine servers. They provides more flexibility and security.

Characteristic of Cloud Computing:

Characteristic of Cloud Computing On-demand self-service Broad network access Resource pooling Rapid elasticity Measured Service

Actors in Cloud Computing:

Actors in Cloud Computing Actors Definition Cloud Customer A person or organization that maintains a business relationship with, and uses service from, Cloud Providers. Cloud Provider A person, organization, or entity responsible for making a service available to interested parties . Cloud Auditor A party that can conduct independent assessment of cloud services, information system operations, performance and security of the cloud implementation Cloud Broker An entity that manages the use, performance and delivery of cloud services, and negotiates relationships between Cloud Providers and Cloud Consumers Cloud Carrier An intermediary that provides connectivity and transport of cloud services from Cloud Providers to Cloud Consumers

Interaction between Actors:

Interaction between Actors

Major Service Layers:

Major Service Layers IaaS Infrastructure as a service PaaS Platform as a service SaaS Software as a service


IaaS Storage CDN Back Up and Recovery Computer Platform Hosting Services Management


PaaS Testing Database Development Business Intelligent Application Deployment


SaaS Collaboration CRM Document Management ERP Billing Sales Email and Office Work HR Social Network Finance

Benefits of SaaS:

Benefits of SaaS Familiarity with WWW Smaller Staff Customization Better Marketing Web Reliability Security More Bandwidth

Storage On Cloud:

Storage On Cloud Several large Web companies are now exploiting the fact that they have data storage capacity that can be hired out to others. Allows data stored remotely to be temporarily cached on desktop computers, mobile phones or other Internet-linked devices. Amazon’s Elastic Compute Cloud (EC2) and Simple Storage Solution (S3) are well known examples.

Amazon S3:

Amazon S3 S imple S torage S ervice (S3) was launched in 2006. It provides simple web service interface. It provides highly scalable data storage infrastructure. It has unlimited data storage. Objects of 1byte to 5 Gigabyte can be created and published over any cloud.

Amazon EC2:

Amazon EC2 Amazon E lastic C ompute C loud (EC2): Elastic, Machine Specification Fairly cheap! Powered by Xen – a Virtual Machine: Different from Vmware and VPC Hardware contributions by Intel (VT-x/Vanderpool) and AMD (AMD-V). Supports “Live Migration” of a virtual machine between hosts. Linux, Windows, OpenSolaris Management Console/AP


Security Privacy consideration is the primary concern. What they are doing to achieve security? Threats: Hackers Bot Attacks

Security Benefits:

Security Benefits Centralized data Reduced Data Loss Monitoring Instant Swap Over Logging

Cloud Vocabulary (1-2):

Cloud Vocabulary (1-2) Cloud Closed Cloud Anything as a Service (XaaS) Automated Provisioning Autoscaling Big Data Cloud Bursting Cloud Portability

Cloud Vocabulary (2-2):

Cloud Vocabulary (2-2) Cloud Sourcing Cloud Storming (Cloud Bursting) DaaS Single Tenant Multi Tenant NoSQL
