Cloud Computing:How to do it right!

Cloud is the new paradigm for IT.

NIST Cloud Definition

5 Essential Characteristics:• On-demand self-service• Broad network access• Resource pooling• Rapid elasticity• Measured Service

4 Deployment Models:• Private• Public• Community• Hybrid

3 Delivery Models:• SaaS• Paas• IaaS

Virtualize & Consolidate Everything

Centralize IT, Policy & Management

Standardize Service Offerings

Automate & Optimize

Assess Tasks Ahead; Determine ROI Where Does Your Journey Begin?

Virtualization Is Necessary,But Not Sufficient

Rationalize Applications

Data Centers are Evolving

But there

will be a

movement

to the right

Many IT architectures will co-exist

Data centers will use hybrid models

Where to Start?

• Low Asset Utilization

• Duplicative Systems

Application Based Silos

• Easier to manage

• Somewhat better utilization

Zones of Virtualization

• Share demand across assets

• More responsive to agency needs

Internal Cloud

• Shift from Asset Ownership

• Better linked to emerging technologies

External Cloud

Step 1 – Assess

Evaluate what applications currently exist

Evaluate what resources currently exist

Analyze workloads against resources– Efficiency too low?

Evaluate who is using which resources– Chargeback/Showback

Step 3 – Execute

Think in terms of buying servicesSaaSPaaSIaaS

SaaS:• Gov-Apps, Internet Services• Blogging/Surveys/Twitter, Social Networking• Information/Knowledge Sharing (Wiki)• Communication (e-mail), Collaboration (e-

meeting)• Productivity Tools (office)• Enterprise Resource Planning (ERP)

IaaS:• Networks, Security, Mainframes, Servers, Storage• Telecom Carrier Services• IT Facilities/Hosting Services

PaaS:• Application Development, Data, Workflow, etc.• Security Services (Single Sign-On, Authentication,

etc.)• Database Management• Directory Services

To Move or Not to Move: The Economics of Cloud Computing*

Results:

• Overall, they found that in-house provisioning is

cost-effective for medium to large workloads, whereas cloud-based options suit small workloads better

• For medium workload intensity, cloud-based options are cost-effective only if the application needs to be supported for 2-3 years, and become expensive for longer-lasting scenarios

• Software licenses can be big expenses for in-house solutions

• Outbound I/O charges can quickly add cost to Cloud based solutions

Call to Action

If you have not done Virtualization yet, Start– Assessment Services– Transform to Private Cloud– Gain Expertise in orchestration, workflow

automation, service levels, and charge-backs Look at Broker services (multiple service providers) Evaluate complete solutions (consistent with shared

infrastructure)
