Cloud Computing
• Instead of having 20 servers …• Pool them together into a gigantic super-server• “Split up” super-server into 100 “virtual” servers• Move resources from one “virtual” server to another
instantly as it’s needed• Share among different users if needed
• That’s Cloud Computing

• Shared compute & storage• Shared/no network security• Non-redundant hosts • Local, non-persistent storage• Not resource balanced
Advantages:• Configure & pay online• Pay by the hour with “spot demand”• API access
Shared Computing Utility – e.g. Amazon, Rackspace
Public Cloud
Internet
Colocation Dedicated Servers Private Clouds
Copyright © 2011 Online Tech. All rights reserved www.onlinetech.com 734.213.2020
Drawbacks:• Availability often not guaranteed• No failover across hosts
– If host crashes & data is lost• Not PCI or HIPPA compliant
Ideal for:• Development & test• Compute intensive research apps• Where crash/loss of data isn’t critical
Shared Computing Utility – e.g. Amazon, Rackspace
Public Cloud
Amazon EC2 Cloud is most likely running on lousy hardware... an instance mysteriously crashed
loosing data

Public Cloud• Short life cycle
projects• Ideal for Dev & Test &
compute intensive research projects
• Non-critical, web front end apps
• Need to spin up & down 100’s servers programmatically
DEPENDS ON THE APPLICATION
Which Cloud Is Right?
Managed Cloud• Enterprise app servers• Secure SaaS apps• Network/data security• Uptime & availability• Need to integrate
dedicated servers, colocation or private clouds
• Managed services• Offsite backup• Warmsite DR• 24x7 monitoring• 24x7 live support
Private Cloud• PCI, HIPAA & SOX• Single tenant enterprise
deployment• Dedicated hardware,
storage & network• I/O intensive apps• Full architectural &
component control• Managed services
• Offsite Backup• Warmsite DR• Hotsite DR• 24x7 support
