The document discusses different types of cloud computing including public cloud, private cloud, infrastructure as a service (IaaS), platform as a service (PaaS), and software as a service (SaaS). It describes Microsoft's Windows Azure platform which provides IaaS and PaaS offerings including compute, storage, networking, and development tools. The platform allows customers to build and host applications at a large global scale using virtual machines, SQL databases, and other cloud services.

2. What is cloud?

3. Public Cloud

4. Pool of computing resources offered by a vendor, typically using a “pay as you go” model

5. Private Cloud

6. Pool of computing resources that lives within a self-managed datacenter

8. Complete control and responsibility

10. Less control, but fewer responsibilities

11. Lower capital costs, but pay for fixed capacity, even if idle

12. Shared

13. multi-tenant environment

14. Offers pool of computing resources, abstracted from infrastructure

16. Types of Clouds Infrastructure as a Service (IaaS) Your Application Deployment Runtimes Web Server Unit of Deployment OS Services Provided by Windows Azure Operating System Provided By Amazon EC2 Virtualized Instance Hardware

17. Types of Clouds Platform as a Service (PaaS) Your Application Deployment Unit of Deployment Runtimes Can swap out Web Server Provided by Google AppEngine OS Services Provided by Windows Azure Operating System Virtualized Instance Hardware

18. Types of Clouds Software as a Service (SaaS) Your Application Runtimes Web Server Provided by SaaS OS Services Operating System Virtualized Instance Hardware

19. Control Versus Economy of Scale Control High Low Economy of Scale Low High

20. This is Not New … Build vs. Buy Control High Low Economy of Scale Low High

21. This is New … On Premises vs. In the Cloud Control High Low Economy of Scale Low High

22. Fundamentals How Microsoft Views the Cloud Scale Out/In Automated Service Management High Availability Multi-Tenancy Considerations Location On premises Off premises Infrastructure Heterogeneous Homogeneous OpEx CapEx Business model Lease/Rented Owned Ownership Third Party Self Management

24. Over provisioned capacity is wasted

25. Time to market can be cumbersome

26. Successful companies need to grow/scale

27. Keeping up w/ growth is big IT challenge

29. Sudden spike impacts performance

30. Can’t over provision for extreme cases

31. Services with micro seasonality trends

32. Peaks due to periodic increased demand

34. Application Services “Dublin” “Velocity” Frameworks “Geneva” Security Access Control Project “Sydney” Connectivity Service Bus SQL Azure Data Sync Data Compute Windows Azure Platform Table Storage Blob Storage Queue Drive Content Delivery Network Storage

39. Windows Azure Compute – instance types: Web Role & Worker Role. Windows Azure applications are built with web role instances, worker role instances, or a combination of both. Operating system as an online service; with automated provisioning and services management Development, service hosting, & management environment .NET, Java PHP, Python, Ruby, native code (C/C++, Win32, etc.) ASP.NET providers, FastCGI, memcached, MySQL, Tomcat Full-trust – supports standard languages and APIs Secure certificate store Management API’s, and logging and diagnostics systems Multiple roles – Web, Worker, Virtual Machine (VHD) Multiple VM sizes 1.6 GHz CPU x64, 1.75GB RAM, 100Mbps network, 250GB volatile storage Small (1X), Medium (2X), Large (4X), X-Large (8X) In-place rolling upgrades, organized by upgrade domains Walk each upgrade domain one at a time Each instance runs on its own VM (virtual machine), replicated as needed The Fabric Controller communicates with every server within the Fabric. It manages Windows Azure, monitors every application, decides where new applications should run – optimizing hardware utilization.

40. SQL Azure Highly available, scalable, and consistent distributed relational database service; with geo-replication and geo-location of data VM 5 VM 6 VM 4 DBA role places more focus on policy/logical management SQL Server SQL Server SQL Server SQL DB SQL DB SQL DB Shared infrastructure at SQL database and below Each user database is replicated to one or more servers (configurable based on SLA) Client requests are routed to current “primary server” for read and write operations (based on SQL session) Security, lockdown and isolation enforced in SQL tier Highly scalable and state-of-the-art HA technology Automatic failure detection; client request re-routed to new primary on failure High SLA guarantee using logical replication (hot standby replicas) Automatic management, self-healing and load balancing across shared resource pool Security Model Uses regular SQL security model Authenticate logins, map to users and roles Authorize users and roles to SQL objects Supports standard SQL logins Logins are username + password strings Service enforces use of SSL to secure credentials Upcoming support for AD Federation, WLID, etc. Connectivity Model Connect using common client libraries ADO.NET, OLE DB, ODBC, etc. Clients connect to a database directly Cannot hop across DBs UserDB1 UserDB2 UserDB3 UserDB4 UserDB1 UserDB2 UserDB3 UserDB4 UserDB1 UserDB2 UserDB3 UserDB4 SQL Azure database provisioning (databases, accounts, roles, …, metering, and billing) Scalability and Availability: fabric, failover, replication, and load balancing

41. Windows Azure platform AppFabric Internet-scoped overlay-network bridging across IP NATs and firewalls with federated access control Service Bus Expose RESTful or SOAP services over the internet through firewall and NAT boundaries Communicate bi-directionally between apps and services in an interoperable manner Choose relays, queues, routers, and other message patterns and types Scale out naturally and reliably as apps and services grow Access Control Integrate authorization into apps to control “what users are allowed to do” Federate with multiple identity systems across organizations and ID providers Easily apply fine-grained access control rules Secure Service Bus communications Scale out naturally and reliably as apps and services grow
