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



Cloud Computing Defined

Navigating The Cloud

On-Demand
Elastic & Scalable
Virtualized Resources
Rapidly Provisioned

Public Cloud
• Third party managed Hybrid Cloud Internal Cloud
• Multi-tenant Private Cloud • Internally hosted
• Self Serve • Mixes Public & Private
• Cap-ex intensive
• Pay as you go • Single & Multi Tenant • Third party managed
• Secure
• Programmable APIs • Expandable • Single tenant
• Less Scalable
• Provision On Demand • Secure
• Internally Managed
• Customizable
• Fully Managed




Public Cloud or Private Cloud?

Utility Model Secure Data & Network
No Contracts Compliance – SOX, PCI, HIPAA
Shared Hardware Dedicated Hardware
Self Managed Fully Managed

Public Cloud
• Secure
• Less Scalable
• Customizable
• Fully Managed




Public Cloud or Private Cloud?
Outsource or Insource?

No Cap-Ex Hardware Selection
Fully Managed Cap-Ex Intensive
SAS-70/PCI Data Center Self-Managed
Offsite Disaster Recovery Retraining
Public Cloud
• Secure
• Less Scalable
• Customizable
• Fully Managed



Public Cloud
Shared Computing Utility – e.g. Amazon, Rackspace

• Shared compute & storage
• Shared/no network security
• Non-redundant hosts
• Local, non-persistent storage
• Not resource balanced

Advantages: Internet

• Configure & pay online
• Pay by the hour with “spot demand”
• API access



Public Cloud
Shared Computing Utility – e.g. Amazon, Rackspace

Drawbacks:
• Availability often not guaranteed
• No failover across hosts
Amazon EC2 Cloud is most likely
– If host crashes & data is lost running on lousy hardware... an
• Not PCI or HIPPA compliant instance mysteriously crashed
loosing data

Ideal for: kaczoanoker on Twitter

• Development & test
• Compute intensive research apps
• Where crash/loss of data isn’t critical



Hosted Private Cloud
Single Tenant Dedicated Cloud

• Dedicated compute & storage
• Dedicated network security
• N+1 hosts, storage & network security
SAN
– Zero maintenance windows
– Automatic failover, high availability Cloud Controller
Dedicated DB Server

• Automatic resource balancing
• Ability to add non-virtualized servers
• Full mix of managed services Internet



Hosted Private Cloud
Single Tenant Dedicated Cloud

Advantages:
• High availability, N+1 infrastructure
• Complete architectural control
SAN
• Dedicated data & network security
• PCI, HIPAA, SOX Compliance Cloud Controller
Dedicated DB Server

Drawbacks:
• No hourly pricing, API access Internet

• Less elasticity than public clouds



ManagedCloud
A More Secure Multi-Tenant Option

• “Slice” of a private cloud
– VMware Enterprise version
– HA (N+1) hosts, storage & security
SAN
• Automatic failover
• Automatic Resource Balancing Cloud Controller

• Dedicated, secure VLAN, FW & IDS/IPS
• “Hybridize” to servers, colo, private cloud
Internet



Managed Cloud
A More Secure Multi-Tenant Option

Advantages:
• High availability, N+1 infrastructure
• Dedicated data & network security
SAN
• Hybridize with physical servers
• Full mix of managed services Cloud Controller

Drawbacks:
• No API access Internet

• PCI/HIPAA depends on auditor
• No architectural control vs. private cloud

Which Cloud Is Right?
DEPENDS ON THE APPLICATION

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



What Analysts Are Saying…
Yankee Group



Wrap Up: Cloud Benefits

• Lower Total Cost of Ownership
• Higher efficiency across a shared infrastructure
• No Capital Expenses
• Completely owned & managed by Cloud provider
• Deploy Projects Faster
• Provisioning in minutes vs. weeks
• Scale as Needed
• Add resources (CPU, RAM, Storage) only when needed



Picking the Right Cloud
Depends on Your Requirements

• Options Range from Public Clouds to Private Clouds
• Selection Depends on:
• Applications
• Security
• Resiliency & Uptime
• Corporate Philosophy
• Support
• Managed Services Required
