  • 1. Server Communication Network Data Processing Information Analysis Server Communication Network Data Processing Information Analysis Cloud computing On-premise computing Thick & Heavy Client Thin & Light Client National Institute of Standards & Technology (NIST): Convenient, on-demand, network access to a shared pool of configurable computing resources that can be rapidly provisioned and released with minimal management effort or service provider interaction
  • 2. • Manually Provisioned • Dedicated Hardware • Fixed Capacity • Pay for Capacity • Capital & Operational Expenses • Managed by System admins • Self-provisioned • Shared Hardware • Elastic Capacity • Pay for Use • Operational Expenses • Managed via APIs 1. Shared / pooled resources 2. Broad network access 3. On-demand self-service 4. Scalable and elastic 5. Metered by use
  • 3. Users Domain for Developers or Implementers Cloud Applications
  • 4. Application Storage Service Server • Agility – Deploy, deliver, standardized resources in less time • Scalability – adjust resources on demand variation • Reduced Overhead – personnel / hardware / peak capacity situations • Improved Economies of Scale – multi-tenant model • Resource Pooling – multiple organization business units • On-demand Pricing – shifting fixed costs to variable base • Accessibility – Internet delivery to mobile, office, home • Performance guarantees • Security/Privacy liability • Absence of industry standards • Compliance and audit acceptance • Migration to different cloud hosting providers Well-known Benefits Well-known Shortcomings ?
  • 5. The cloud creates more opportunities for entrepreneurs in IT The focus shifts from building cloud environments to efficiently running them Private clouds will become increasingly important Increasing importance of the cloud Hybrid clouds will become more important Enterprise IT will take ownership of cloud adoption Enterprises to start catching up to SMBs in cloud spending Enterprises will demand portability between different vendor's clouds Cloud benefits will become more recognizable Contingency planning will increasingly involve the cloud
  • 6. Eric Schmidt Google CEO 2006 “We're moving into the era of ‘cloud’computing, with information and applications hosted in the diffuse atmosphere of cyberspace …” GRID Computing in Early 1990s Utility Computing in Late 1990s Software-As-A-Service in Early 2000s
  • 7. Mobile device + mobile OS + Browser + Storage + Server + App + Development Environment + Cloud platform … Dependent upon the TARGET application Boundary getting not clear
