  1. Cloud Computing By MihirChitnis

  2. Cloud Computing Misconceptions • “Cloud” – an image used to represent Internet or a large foreign network in a diagram. • Cloud Computing: By General public • “virtual servers on the Internet” • “A buzz word, nothing more” • “Its everything of the future” • “Google?”

  3. Why understand Cloud Computing?

  4. Cloud Computing - Introduction • Higher abstraction of • Grid Computing • Distributed Computing • Multiple concurrent processes over multiple hardware & software systems • Utility Computing • Metered service providing storage and computation • Eg: SalesForce • Is at an early stage.

  5. Cloud Computing Features • Self Healing – self maintaining, automated recovery • SLA-Driven – automated resource management • Multi-tenancy – share infrastructure with controlled translucency • Service-oriented – allows applications from discrete services. • Virtualized – One or multiple computers • Linearly scalable (Eg:1x for a server / 2x for two servers) • Data, Data, Data – share, store and relate information

  6. Cloudware • A platform which supports Eg: GigaSpaceseXtreme Application Platform (XAP)

  7. Cloud Computing Vs Grid Computing

  8. Some Cloud Computing Services • Google Apps • Messaging - Emails & Chats • Collaboration - Documents, Video and Sites • Security • Microsoft Azure • Integrated development ,Service hosting & management environment maintained at Microsoft Datacenters.

  9. Google Apps

  10. Microsoft Azure

  11. Microsoft Azure • Role Based Implementation • Web Role - Web based services. (HTTP,FTP) • Worker Role - Computational Services • Fabric Deployment – scalable hosting • WASS – Windows Azure Storage Service • Cross Platform – Web Services • Built-in management services • Advanced Tracking and logging facilities.
