Tom Hollingsworth @NetworkingNerd CCIE #29213, VCP5
What Is “The Cloud”? • CompuBng as a service, not a product • OS & Device Independent • Reliability and Scalability • Allows Focus on Your Goals, Not Technology
Haven’t I Seen This Before? • ApplicaBon Service Providers • Hosted SoluBons • Service-‐Oriented Architechture
Not A Dirty Word • *aaS – (something) as a Service • SaaS – ApplicaBon (Office 365, Google Apps) • PaaS – PlaXorm (MicrosoZ Azure) • IaaS – Infrastructure (like Amazon EC2)
• ITaaS – IT Outsourcing (Managed Services)
Public or Private?
Public Cloud
• Hosted somewhere else • Accessed via the Internet • Pay-‐per-‐use
Private Cloud
• Hosted Internally • Secure access via internal network • More Up Front Costs
Public Pricing As of 2/7/2012
Who’s Data Is It? • Data on someone’s servers – Who Owns It? • Where is your data being stored? • Contract expiraBon, bankruptcy, theZ • Know your rights before you sign a contract
More Bandwidth • Cloud services require lots of bandwidth • Low latency key for certain apps • QoS can help with contenBon, not oversubscripBon
Disaster Recovery • Cloud data is sBll not invulnerable • Proper DR/BC planning is sBll key • Check contracts for outage windows and SLAs
