1 Cloud Computing, Virtualization & Green IT

2 Cloud computing can change how IT supports business Consider the following: As much as 85% of computing capacity sits idle in distributed computing environments. Seventy percent of IT budgets is typically spent on maintaining current IT infrastructures and only 30% is typically spent on new capabilities. Over 30% of consumers notified of a security breach will terminate their relationship with the company that contributed to the breach.

3 Defining Cloud Computing Cloud computing has emerged as a new paradigm for: Hosting services Delivery services Allows enterprises to start from small and increase resources on requirement

4 Defining Cloud Computing Cloud computing is a new consumption and delivery model for information technology (IT) and business services and is characterized by: On demand self service Reliable network access Location independent resource pooling Rapid elasticity and provisioning Pay per use

5 Cloud and Environmental Sustainability

6 Cloud Computing

7 Customer View & Providers View

8 Cloud Application Application rum on user machines via web browser, hosted desktop or remote client. User never purchase expensive software licenses Cost is incorporated into subscription fees. Removes burden of software maintenance, ongoing operations

9 Cloud platform Middle layer which provides computing platform or framework as a services Dynamically provisions, configures, reconfigures, and de provisions servers as needed for demand Real distributed computing environment where many services pull together to deliver an application or infrastructure request

10 Cloud Infrastructure Foundation of cloud pyramid Deliver IT infrastructure through virtualization Infrastructure includes servers, networks, and other hardware appliances Virtualization allows physical piece of hardware into independent, self governed environments which can be scaled in terms of CPU, memory, storage capacity & other elements

15 Benefits with Cloud Removal/reduction of capital expenditure Reduced administrative cost Improved resource utilization Economies of scale Scalability on demand Quick and easy implementation Anywhere access Helps smaller business

16 Challenges with Cloud Less job opportunities for IT staff Security Risk Internet outage will be a serious problem

17 Business Impact of Server Consolidation with Virtualization

18 State of Infrastructure Today Server Sprawl 36M physical x86 servers by a ten fold increase in 15 years 1 $140 bn in excess server capacity a 3 year supply 2 Power & Cooling 50c for every $1 spent on servers 2 $29 bn in power and cooling industry wide 2 Space Crunch $1,000 / sqft 2 $2,400 / server 2 $40,000 / rack 2 Operating Cost $8 in maintenance for every $1 spent on new infrastructure : 1 server to admin ratio 3 1.

19 Virtualization Can Help Using virtual infrastructure, we can offer the same levels of service and more flexibility for up to 40 percent lower server and operating costs Pragmatic Approaches To Server Virtualization, Forrester, June

20 Server consolidation with Virtualization

21 Reduce Excess Server Capacity Servers Storage Network Facilities BEFORE Virtualization 1,000 Direct attach 3000 cables/ports 200 racks 400 power whips AFTER Virtualization 80 Tiered SAN and NAS 400 cables/ports 10 racks 20 power whips 21

22 Cut Related Data Center Requirements BEFORE AFTER 3 network ports per server 3000 network ports / cables 200 racks and 2,000 sq ft. 5 network ports per host 400 network ports / cables 10 racks and 250 sq ft. $296 network savings per workload over 3 years $430 space savings per workload over 3 years 22

23 Benefits of Consolidation 3-Year Cost Savings / Workload Fewer Servers to Manage Less Power required Less Space needed Less Cabling required Server Hardware $5,816 Power Costs $759 Cooling Costs $949 Data Center Real Estate Network Infrastructure $431 $296 TOTAL $8,251 23

24 Benefit of Instant Provisioning BEFORE Virtualization Procure hardware AFTER Virtualization Configure hardware Install OS Configur e OS & Tools Assign Configure IP AddrNetwork hrs of work Deploy from Template Power on VM <1 hour of work 1 2 days lead time 4 6 week lead time Provisioning time reduced to minutes instead of days or weeks 24

25 Traditional Process vs. Virtual Infrastructure Key Task Moving an application to a new server Hardware maintenance Traditional Approach 4-6 hours for migration Service interrupted for duration of maintenance window Requires days/weeks of change management preparation Requires 1-3 hour maintenance window Requires days/weeks of change management preparation Virtual Infrastructure Approach 2-5 minutes for live migration Zero downtime hardware upgrades 25

26 Free Up $$$ from Maintenance to Innovation BEFORE AFTER Infrastructure maintenance 42% Application maintenance 30% Application innovation 23% Application maintenance 15% Infrastructure maintenance 30% Application innovation 45% Infrastructure innovation 5% Source: Fortune 100 Company 26 Infrastructure innovation 10%
