Navigating The World of Cloud Computing

Mike KleinPresident, Online Tech



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

Navigating The Cloud

On-DemandElastic & ScalableVirtualized ResourcesRapidly Provisioned

Public Cloud• Third party managed• Multi-tenant• Self Serve• Pay as you go• Programmable APIs

Private Cloud• Third party managed• Single tenant• Secure• Customizable• Fully Managed

Internal Cloud• Internally hosted• Cap-ex intensive• Secure• Less Scalable• Internally Managed

Hybrid Cloud• Mixes Public & Private • Single & Multi Tenant• Expandable• Provision On Demand

Hardware SelectionCap-Ex IntensiveSelf-ManagedRetraining



• 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



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

• Dedicated compute & storage • Dedicated network security• N+1 hosts, storage & network security

– Zero maintenance windows– Automatic failover, high availability

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

Single Tenant Dedicated Cloud

Hosted Private Cloud

SAN

Cloud ControllerDedicated DB Server

Internet



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

Drawbacks:• No hourly pricing, API access• Less elasticity than public clouds

Single Tenant Dedicated Cloud

Hosted Private Cloud

Cloud ControllerDedicated DB Server

Internet



• “Slice” of a private cloud– VMware Enterprise version– HA (N+1) hosts, storage & security

• Automatic failover• Automatic Resource Balancing• Dedicated, secure VLAN, FW & IDS/IPS• “Hybridize” to servers, colo, private cloud

Public versus Private Cloud Options

Comparing Cloud Options



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

What Analysts Are Saying…



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

• Options Range from Public Clouds to Private Clouds• Selection Depends on:

• Applications• Security• Resiliency & Uptime• Corporate Philosophy• Support • Managed Services Required

Depends on Your Requirements
