Application models for utility computing

2. Application models for utility computing Ulrich (Uli) Homann Chief Architect, WW Enterprise Services Microsoft Corp. Session Code: ARC307

3. Session Objectives And Takeaways • Highlight the looming energy crisis in the data center • Understand the application designers role in reducing energy consumption • Understand how virtualization can support you in going Green

4. Will your Data Centers be Rated by the Government? • Outcome: EPA Energy Star Program • Energy Star for Servers May 2009 release • Energy Star for DCs Jan 2010 release Congress Passed Public Law 109-431 Dec 2006 EPA to study and promote IT Efficiency EPA provided response August 2007 http://www.energystar.gov/index.cfm?c=prod_development.server_efficiency http://www.energystar.gov/ia/partners/prod_development/downloads/EPA_Datacenter_Report_Congress_Final1.pdf 4

5. In the US: Capacity Growth = 0.8%/yr Usage Growth = 1.1%/yr DC Growth = 15%/yr Why the Government Cares? Today in US 1.8 to 2.0% US Projections: 2020  10% 2030  30-40% 5

6. All of this Drives Costs - Data Center Economics have Changed! DC Energy Belady, C., “In the Data Center, Power and Cooling Costs More than IT Equipment it Supports” Electronics Cooling Magazine (Feb 2007) 6

7. Where Data Center Power Goes Utility Load PUE = ------------------ = 2 IT Load Source: EYP Mission Critical Facilities Inc., New York Microsoft is focusing on all the pieces of the pie 7

8. “Sins” of our fathers From an application development perspective

9. Synchronicty is Dead

10. “Success” - a design tenet

11. SOYP – capacity planning methodology

12. Application architects – Belts-and-suspenders people?

13. Solution approaches

14. Constraint based planning Energy Spend • You can: • Increase DC count • Hold # DC • Decrease # DC • With a corresponding • Increase Capacity • Hold capacity steady • Decrease Capacity Service Units Available Service Units Consumed • You can: • Increase DC size • Hold DC Size • Decrease DC size • With a corresponding • Increase power $$ • No change • Increase flexibility at a cost of faster to full Data Center #’s of DC’s Key lesson: Servers use vital resources whether on or off

15. Trends in DC design • Configuration & Construction • Modularize the Data Center • Use the same kit of parts in pre-manufactured modules • Solution to accept racks, skids or containers • Redundancy & Reliability customized to each DC Class • Facility to accommodate Variable Power Density • Cost • Reduce capital cost/MW by Class • Leverage industry to drive down initial & operating costs • Time To Market - Move to lowest $ Cost DC investment • Data Center Facility delivered with the servers • >ROIC – return on invested capital • Sustainability • Lowest yearly average PUE in the Industry • 2008 < 1.5, 2010 < 1.25, 2012 < 1.125 • Calculate TCOE not just operational efficiency • Initiative to reduce building, copper, water • Drive to Chiller-less data centers and aggressive outside economization

16. Next Gen DC - Key Characteristics • Modular • Scalable • Plug-and-play infrastructure • Factory pre-assembled PACs & PMBs • Rapid deployment • Demountable • "Fail Small“ • Reduce TTM • Reduced construction • Sustainable measures Pre-assembled containers (PAC) Pre-manufactured buildings (PMB)

17. A Responsible Dynamic Topology? SQL ASP ASP ASP ASP ASP IIS IIS IIS IIS IIS

18. Key transformation elements Approach: • Modular • As-needed reliability • As-needed maintainability • Manufacturing-oriented • Services-based

19. Services-based approach

21. Segment your solution Service Model <ITService> <Site> <Server Group> Simple topology view <Server> <ServerRole>

22. Server (workload) segmentation • Server Groups manage like servers (workloads); • Today Server Groups are static – numbers of instances are effectively fixed; • Enable your solutions and deployment to allow the infrastructure to reduce and increase the numbers of servers in any given server group at any given time; The term “server” doesn’t mean what it used to anymore!

23. Server Role segmentation • Introduce Server Roles as part of your solution • Going from component to Services is not granular enough • Group related functionality in Server Roles • E.g. Payrolls, general ledger • Plan your Services deployment with Server Role isolation in mind • Allow the infrastructure to dynamically start and stop server roles (deployed as VM’s)

24. Start slow and grow in ‘scale units’ • Pete’s SharePoint order (representing max growth): • 50,000 users • 20,000 team sites • 150MB/site • Responses per second: 100 • Monitoring counters in the operational configuration and monitoring environment (SC OM 2007) trigger growth (or shrink) provisioning once the specific capacity driver hits 80% of specified value: • Growth based upon RPS (growth type A): initial size – 99 RPS; counter is set to 80 RPS • Growth based upon content db size (growth type B): initial size – 0.8 TB; counter is set to 0.7 TB

25. Projected Load Profile

26. Load by Time of Day

27. Enable Virtualization and "Run Full" • Decompose application into work loads (servers) that can be dynamically scheduled • Break dependencies between your product’s services • Allow customers to pick time of day, day of week, etc, and allocate capacity of individual parts dynamically • If one server role is “out” right now, application should not break • Define scale units for your server roles so that they can be reduced in size to a minimal level and grown in chunks • Application server roles should not break if resources get allocated by quota by application role • (20% CPU for you, 60% for you) • Monitoring can no longer assume all parts are “on” at all times. • Server roles become dependency bound for scheduling of parts that need to run together. • If inseparable parts, put in same server role, deploy in same image • Break up the work types that your application does so they can operate out of band over units of time • Synchronicity (scale out) is not by server. It is by virtual server image. • Parts communicate across images
