Navigating the World of Cloud Computing

Cloud computing has transformed the landscape of IT with its promise of application availability, disaster recovery, and reduced costs. Understanding the spectrum of options—private, hybrid, managed, and public clouds—is essential for businesses. This article discusses key drivers like speed to market and lower total cost of ownership, real-life examples such as disaster recovery in hours, and the implications of cloud computing for different enterprise needs. With increasing security and compliance requirements, businesses must navigate potential opportunities and risks in the cloud landscape. ###

  2. Growth in Cloud Computing Source: Tier1 Research

  3. Cloud Computing: Threat or Opportunity?

  4. Key Business Drivers • Application Availability • Disaster Recovery • Speed (Time to Market) • CapExFree IT • Lower Total Cost of Ownership

  5. What Does This Mean? Real Life Examples: • Survival of a server failure • Zero maintenance windows • Complete offsite disaster recovery in hours • Spin up new SaaS servers in minutes • Testing new releases on production server snapshot

  6. Cloud Computing Spectrum PrivateCloud HybridCloud ManagedCloud PublicCloud

  7. Cloud Computing Spectrum PrivateCloud HybridCloud ManagedCloud PublicCloud • Dedicated/Single Tenant • High Availability Model • Monthly Pricing • Dedicated/Auditable Security • Compliant – SOX, PCI, HIPAA • Complete Architectural Control • Plug & Play • One-Click DR (Disaster Recovery) • Multi-Tenant • Cost-Driven Utility Model • Hourly Pricing • Limited/Shared Security • Compliance? • No Architectural Control • Programming APIs • Extensive Programming DR

  8. Private Cloud Single Tenant Dedicated Cloud • High Availability (N+1) Architecture • Zero maintenance windows • Automatic failover & resource balancing • Dedicated data & network security • Hybrid with non-virtualized servers • PCI, HIPAA, SOX Compliance Drawbacks: • No hourly pricing, API access • Less elastic than public clouds SAN Dedicated DB Server Internet

  9. Public Cloud (e.g. Amazon) Compute as Utility Model • Shared, non-redundant hosts • Local, non-persistent storage • Configure & pay online • Pay by the hour with “spot demand” • API access Drawbacks: • Availability often not guaranteed • Complex pricing model • No failover - If host crashes, data is lost • Not PCI or HIPPA compliant Internet Amazon EC2 Cloud is most likely running on lousy hardware... an instance mysteriously crashed loosing data kaczoanoker on Twitter

  10. Managed Cloud More Secure Multi-Tenant Option • “Slice” of a High Availability Private Cloud • Automatic failover & resource balancing • Dedicated data & network security • Hybrid with non-virtualized servers • PCI, HIPAA, SOX Compliance Drawbacks: • No hourly pricing, API access • No architectural control vs. private cloud SAN Internet

  11. Which Cloud is Right? PrivateCloud HybridCloud ManagedCloud PublicCloud • Large Enterprises • Single Tenant Req’t • Highest Security Req’t • PCI/HIPAA/SOX • Need Arch Control • I/O Intensive Apps • Integrate Legacy Systems (w/ Colo) • Critical + NonCritical Apps • Enterprise Apps • Enterprise Security • PCI/HIPAA/SOX • SaaS applications • Test & Dev Systems • Short Life Cycle • Noncritical Apps • Compute Intensive • Highly Elastic Apps

  12. 2011 Cloud Trends

  13. 2011 Cloud Trends • More Confusion (Not Less) • Computing as a Utility on the Low End • Managed Clouds Address Application Availability • Enterprises Adopting Private Clouds • Bar is Raising for Hosting Standards • Security & Compliance • Disaster Recovery

  14. More Confusion (Not Less) Opportunity: Educate Your Clients

  15. Low End Compute as Utility Public Cloud Computing • Amazon Leading Change • Designed for Commodity Pricing • Non-Redundant Hosts • Non-Persistent Storage • No Failover/Availability • Programming req’d for availability & DR • Complex Costing Model • Spot Pricing Market Opportunity: Programmers & System Designers

  16. Managed Cloud Emerging Managed Cloud Computing • High Availability, N+1 Infrastructure • “Slice” of a Private Cloud • VMware Enterprise version • N+1 Hosts, Storage & Security • Automatic Failover • Full Mix of Managed Services Opportunity: Differentiatevs Commodity

  17. Enterprises Adopting Private Clouds Single Tenant, Dedicated Private Cloud • Yankee Group: 67% Prefer Private Cloud • Security & Compliance Are Major Drivers • More Cost-Effective for Most Enterprises • Complete Architectural Control • Dedicated Data & Network Security • PCI, HIPAA, SOX Compliance Opportunity: Enterprise Computing for SMB

  18. Raising the Bar on Hosting Standards • Auditing Standards Are Getting Tougher • SAS 70 -> SSAE 16 -> SOC 2/SOC 3 • SOC 2/SOC 3 Separates Men from Boys • HIPAA & PCI • Expect Shake Out in Public Cloud Market • 100’s + Amazon, Google, Microsoft, Rackspace … • Regional Players Lead in Private & Managed Clouds • Hands-on, Face-to-Face Support • High Trust Business

  19. Security & Compliance • Security Concerns Are Significant • 51%: Security #1 Reason Not to Cloud • Highlighted by Recent Breaches • Google, Sony • $1.5M/incident HIPAA fines • #1 Driver to Private Cloud • Single Tenant, Dedicated Network & Data Security • SOX, HIPAA & PCI are Key Drivers Opportunity: Solve HIPAA, SOX, PCI Pain

  20. Disaster Recovery

  21. Conventional Backup & D/R Trade-offs

  22. The Cloud Shifts the D/R Curve

  23. Navigating the World of Cloud Computing • Which Cloud is Right for Your Clients? • Private Cloud • Public Cloud • Managed Cloud • Key Issues to Consider: • Security • Compliance • Availability • Disaster Recovery
