Benefits Issues Slide 9: Difficult to deploy applications in new environment DEPLOYMENT MODEL OF CLOUD COMPUTING : DEPLOYMENT MODEL OF CLOUD COMPUTING TYPES OF CLOUD COMPUTING : TYPES OF CLOUD COMPUTING ❶ PRIVATE CLOUD ❷ PUBLIC CLOUD ❸ COMMUNITY CLOUD ❹ HYBRID CLOUD PRIVATE CLOUD:- : PRIVATE CLOUD:- a.k.a. internal cloud/ corporate cloud provides hosted services to a limited number of people offerings capitalize on data security, corporate governance, and reliability concerns PUBLIC CLOUD :- : PUBLIC CLOUD :- a.k.a. external cloud Service provider makes resources dynamically available Benefits:- - easy and inexpensive set-up - scalability - no wasted resources Examples :- Amazon Elastic Compute Cloud, IBM's Blue Cloud, Sun Cloud, Google AppEngine COMMUNITY CLOUD:- : COMMUNITY CLOUD:- Organization having similar requirement Privacy , security and/or policy compliance Examples:- Google’s "Gov Cloud" HYBRID CLOUD:- : HYBRID CLOUD:- Multiple internal and external providers Composition of two or more clouds Applications: - Archiving and backup functions - Deploying a web application in the cloud Layers in cloud computing : Layers in cloud computing The five layers : The five layers Client : Client Hardware & Software Essentially useless without the cloud E.g.: Computers\phones Application (SaaS) : Application (SaaS) Run over internet No need to install\maintain Complete, customizable applications E.g.: Google Apps, Salesforce CRM Platform (PaaS) : Platform (PaaS) Deployment without complexity Eliminate most management tasks Pre-built components E.g.: Google App Engine, Microsoft Azure Infrastructure (IaaS) : Infrastructure (IaaS) Network of servers Virtualized Billed on utility basis E.g.: Nimbus, AWS Server : Server Hardware\Software Specialized for cloud (e.g. better OS, multi-core processors) Network of virtualized computers HOW CLOUD COMPUTING WORKS? : HOW CLOUD COMPUTING WORKS? Slide 33: Can logically be divided into 2 sections -Front end -Back end Front end Network Back end Slide 34: Front end includes - -the client's computers -application required to access the cloud computing e.g. Internet Explorer, FireFox etc. Back end includes - -computer networks, servers and any data storage systems -practically, any computer program you can imagine from data processing to video games -Control node…also called as Central server Slide 35: Webmail – A Simple Cloud Computing Example Slide 36: Different Cloud Computing Variations Benefits of cloud computing: : Benefits of cloud computing: Slide 39: Agility Cost Slide 40: Multi-tenancy Centralization Peak-load capacity Utilization and efficiency Device and Location Independent Maintenance Issues in Cloud Computing : Issues in Cloud Computing Slide 42: Privacy --relatively immune to traditional privacy breaches --no control mechanism Open Source --provide foundation : Open Source --provide foundation Ownership --rights related issue Security : Security --vulnerability of remote data Availability & Performance : Availability & Performance --able to control backups --crash of service Sustainability & Reliability : Sustainability & Reliability --is data storage system trustworthy? --is cloud service provider financially stable?
