1. Demystifying Cloud Computing Zoli Herczeg Evangelist Microsoft Romania zoli.herczeg@microsoft.com http://zoli.herczeg.ro *Inspired by Simon Guest’s ITS204 session @TechEd Europe 2009

2. Demystifying Cloud Computing This is Jim

3. Demystifying Cloud Computing Jim’s Boss (the CIO) has asked him to “move their company to the cloud”

4. Demystifying Cloud Computing Jim has no idea what this means

5. Demystifying Cloud Computing Jim has heard of cloud computing, but is lost when it comes to the terminology

6. Demystifying Cloud Computing Is cloud computing just about virtualization? http://www.computerworld.com/action/article.do?command=viewArticleBasic&articleId=9121923

7. Demystifying Cloud Computing Is cloud computing just another term for SaaS? http://www.daniweb.com/blogs/entry3993.html#

8. Demystifying Cloud Computing Is cloud computing something new? http://www.cloudviews.org/2009/01/is-this-cloud-thing-something-new/

9. Demystifying Cloud Computing Is cloud computing for stupid people?! http://cloudcomputing.sys-con.com/node/692407

10. Demystifying Cloud Computing Help Jim “demystify” the cloud

11. Demystifying Cloud Computing Help him understand the terminology

12. Demystifying Cloud Computing Show Jim what applications make sense in the cloud, and why

13. Demystifying Cloud Computing Teach Jim the important considerations for moving to the cloud

14. Terminology

15. SOA – Service Oriented Architecture

16. Terminology SaaS – Software as a Service

17. Terminology Web 2.0

18. Terminology RIA – Rich Internet Applications

19. Terminology Software + Services

20. Terminology Are any of these cloud computing?

21. Terminology These are styles of application architecture

22. Terminology Instead, we need to look at where applications live

23. Where does my application live?

24. On Premises

25. Where does my application live? Application runs on-premises Buy my own hardware, and manage my own data center Application runs on-premises Bring my own machines, connectivity, software, etc. Complete control and responsibility Upfront capital costs for the infrastructure

26. Where does my application live? Hosted

27. Where does my application live? Application runs on-premises Buy my own hardware, and manage my own data center Application runs at a hoster Pay someone to host my application using hardware that I specify Application runs on-premises Bring my own machines, connectivity, software, etc. Complete control and responsibility Upfront capital costs for the infrastructure Application runs at a hoster Rent machines, connectivity, software Less control, but fewer responsibilities Lower capital costs, but pay for fixed capacity, even if idle

28. Where does my application live? Cloud

29. Where does my application live? Application runs on-premises Buy my own hardware, and manage my own data center Application runs at a hoster Pay someone to host my application using hardware that I specify Application runs using cloud platform Pay someone for a pool of computing resources that can be applied to a set of applications Application runs on-premises Bring my own machines, connectivity, software, etc. Complete control and responsibility Upfront capital costs for the infrastructure Application runs at a hoster Rent machines, connectivity, software Less control, but fewer responsibilities Lower capital costs, but pay for fixed capacity, even if idle Application runs using cloud platform Shared, multi-tenant environment Offers pool of computing resources, abstracted from infrastructure Pay as you go

30. Where does my application live? Public Cloud

31. Where does my application live? Pool of computing resources offered from a vendor

32. Where does my application live? Private Cloud

33. Where does my application live? Pool of computing resources that lives within a self managed datacenter

34. Where does my application live? Pool of computing resources that lives within a datacenter with no sharing

35. Where does my application live? Jim now understands the style of an application, and where it lives, but who creates the application?

36. Where does my application live? Build vs. Buy

37. Where does my application live? Application runs on-premises Application runs at a hoster Application runs using cloud platform Build vs. Buy Build Buy “Packaged” Application An application that I buy “off the shelf” and run myself “Home Built” Application An application that I develop and run myself Hosted “Home Built” An application that I develop myself, but run at a hoster Hosted “Packaged” An application that I buy “off the shelf” and then run at a hoster Cloud Platform An application that I develop myself, that I run in the cloud “Software as a Service” A hosted application that I buy from a vendor

38. Jim’s Applications

67. Platform Services Software Services Application Services Infrastructure Services The Microsoft Cloud Categories of Services

68. Storage Dynamic Tabular Data Blobs Message Queues Distributed File System Content Distribution Data Transact-SQL Data Synchronization Relational Database ADO.NET, ODBC, PHP Connectivity Registry On-Premise Bridging Service Bus Security Claims-Based Identity Federated Identities Secure Token Service Declarative Policies Application Services Application Marketplace Information Marketplace Personal Data Repository Frameworks Workflow Hosting Distributed Cache Services Hosting Windows Azure Platform Compute C / C++ Win32 VHD

69. Microsoft and Cloud Computing How does Windows Azure compare with Amazon and Google’s offerings?

70. Microsoft and Cloud Computing Different Models Infrastructure as a Service (IaaS) vs. Platform as a Service (PaaS)

71. Microsoft and Cloud Computing Operating System Web Server Frameworks Your Application OS Services Deployment Provided By Amazon EC2 Virtualized Instance Hardware Provided by Windows Azure Deployment

72. Microsoft and Cloud Computing Operating System Web Server Frameworks Your Application OS Services Provided by Google AppEngine Virtualized Instance Hardware Deployment Provided by Windows Azure Deployment

73. Your datacenter is not like a cloud datacenter

74. Different replacement strategy NIC Server Rack Container

75. Your datacenter is not like a cloud datacenter

76. The Microsoft Cloud >Purpose-built data centre to accommodate containers at large scale  Cost $500 million, 100,000 square foot facility (10 football fields) >40 foot shipping containers can house as many as 2,500 servers  Density of 10 times amount of compute in equivalent space in traditional data centre >Can deliver an average PUE of 1.22  Power Usage Effectiveness benchmark from The Green Grid™ consortium on energy efficiency Data Center Infrastructure

77. The Microsoft Cloud Data Center Infrastructure

78. The Microsoft Cloud Data Center Infrastructure

79. Your datacenter is not like a cloud datacenter Jim’s team’s approach to application architecture has to change

80. Your datacenter is not like a cloud datacenter Away from the approach of a single application running on a single machine

81. Your datacenter is not like a cloud datacenter Need to move from Synchronous models to Asynchronous

82. Your datacenter is not like a cloud datacenter Need to move from ACID transaction model to BASE transaction model

83. Your datacenter is not like a cloud datacenter ACID = Atomic, Consistent, Isolated, Durable (traditional transactional commit model)

84. Your datacenter is not like a cloud datacenter Really difficult to implement ACID transactions in distributed systems (actually an anti-pattern)

85. Your datacenter is not like a cloud datacenter BASE = Basically Available, Soft state, Eventually consistent

86. Your datacenter is not like a cloud datacenter It’s OK to be wrong, as long as consistency is achieved eventually

87. Your datacenter is not like a cloud datacenter Compare the cost of an apology vs. the cost of knowing for sure

88. Your datacenter is not like a cloud datacenter 6.9 million copies of “The Half Blood Prince” were sold in the first 24 hours of release in the US http://en.wikipedia.org/wiki/Harry_Potter#cite_note-bbc-hbp-record-95

89. Your datacenter is not like a cloud datacenter If you were the online bookstore selling those 6.9 million copies would you optimize for ACID or BASE consistency?

90. Your datacenter is not like a cloud datacenter If you accidentally oversell by a few books, it’s OK to apologize

91. Your datacenter is not like a cloud datacenter “If my application is running in one of these massive datacenters, it’s not very “green” is it?”

92. Green IT and Cloud Computing The cost to buy a server is cheaper than the cost to run (power) a server

93. Green IT and Cloud Computing Datacenter Power Consumption Chart Power Conversion Cooling Hoteling Systems

94. Green IT and Cloud Computing http://download.microsoft.com/download/a/7/b/a7b72ab1-ca17-4589-923a-83b0ff57be6d/Energy-Efficiency-Best-Practices-in-Microsoft-Data- Center-Operations-CeBIT.doc Follows Moore’s Law

95. Green IT and Cloud Computing Jim can barely keep his eyes open. Why is this important to him? He’s not running a cloud data center…

96. Green IT and Cloud Computing True; but running applications in the cloud means that Jim “inherits” the green profile (PUE) of that datacenter

97. Green IT and Cloud Computing May be of little consequence now, but what happens in 5, 10, 15 years time when regulations get stricter about PUE?

98. Green IT and Cloud Computing Fair point – good to know that you are on it

99. Identity in the Cloud “…I have a great new idea for a cloud application. Will it make me rich!?! :-)”

100. Show me the Money!!!

101. DELL PowerEdge M600 = $4,689

102. Show me the Money!!! 10 of those = $46,890

103. Show me the Money!!! $0.30 per compute hour (High CPU)

104. Show me the Money!!! The same $46,890 would buy you 156,300 compute hours

105. Show me the Money!!! 651.25 compute days for 10 instances

106. Show me the Money!!! 21.4 compute months for 10 instances

107. Show me the Money!!! Let’s not forget however… Bandwidth is not free

108. Show me the Money!!! Jim’s get-rich-quick idea is a new cloud based application for Blu-ray movies!

109. Pricing  Compute $0.12 / CPU hour  Storage $0.15 / GB / month $0.01 / 10k txn / month  Bandwidth $0.10 in / GB $0.15 out / GB  Web Edition (1GB) $9.99 / month  Business Edition (10GB) $99.99 / month  Bandwidth $0.10 in / GB $0.15 out / GB  Service Bus $0.15 / 100k messages  Access Control $0.15 / 100k tokens  Bandwidth $0.10 in / GB $0.15 out / GB SUBSCRIPTIONCONSUMPTIONVOLUME LICENSING “Pay as you go and grow” Available at launch Low barrier to entry and flexibility Optimized for cloud elasticity Discounts for commitment Plans for payment predictability “Coordinated purchasing” Planned for FY11 Unified purchasing through EA Introduction to volume discounts “Value for a commitment“ Select offers Announced

110. Show me the Money!!! The Point? Sometimes that we forget we are not in a lab!

111. Show me the Money!!! Cloud computing opens up new and interesting possibilities, but don’t forget the business model!
