Cloud computing: Cloud computing Roll Number Name 081080101 Kiran Anumalla 081080103 Rupesh Balgude 081080115 Rahul Dolas 081080024 Navneet Kambo 081080125 Anirudh Kanth 081080136 Yogesh Pawar Overview: Overview Evolution of cloud computing Types of cloud computing Layers in cloud computing How cloud computing works? Benefits Issues PowerPoint Presentation: 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? PowerPoint Presentation: Can logically be divided into 2 sections -Front end -Back end Front end Network Back end PowerPoint Presentation: 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 PowerPoint Presentation: Webmail – A Simple Cloud Computing Example PowerPoint Presentation: Different Cloud Computing Variations Benefits of cloud computing:: Benefits of cloud computing: PowerPoint Presentation: Agility Cost PowerPoint Presentation: Multi-tenancy Centralization Peak-load capacity Utilization and efficiency Device and Location Independent Maintenance Issues in Cloud Computing: Issues in Cloud Computing PowerPoint Presentation:  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? Conclusion: Conclusion “Go Cloud” References: References http://www.dataplex.com/blog/index.php/2010/01/07/cloud-computing-issues/ http://en.wikipedia.org/wiki/Cloud_computing#Issues http://en.wikipedia.org/wiki/Cloud_computing http://www.cloudbzz.com/clouds-have-layers/ http://cloudcomputing.sys-con.com/node/1200642 Thank you: Thank you Questions: Questions
