Cloud Computing
What is Cloud Computing?
Cloud computing is the provision of dynamically scalable and often virtualized resources as a service over the Internet on a utility basis.
What is Cloud Computing?
Cloud computing is an elastic & scalable compute resource on demand
Cloud computing is not a technology, it’s a way of THINKING
Cloud as a way of THINKING• Existing technologies adopted in a new way
• Utility model is welcomed by small companies and
enterprises
• Symbiosis of IT Professionals and Developers called
DevOps
Cloud Computing Offerings

Cloud Computing Patterns
On and Off• On and off workloads (e.g. batch job)• Over provisioned capacity is wasted • Time to market can be cumbersome

Windows Azure ComputeCloud Operating System
Provides on demand, scalable hosting capabilities
Windows Azure Compute• Instance = Virtual Machine
• Role = Type of Server (Web, Application)
• Accessible and Manageable via API
• Read-only RDP Connection
Windows Azure Compute
Windows Azure Compute
• Windows Server x64 2008 / 2008 R2
• .NET Framework 3.5 SP1 / 4.0
• Native Code, PHP, Java, <your runtime here>
• Full Trust and Admin Mode
Web RoleWorker Role
Windows Azure Compute
• Role is an executable
• HTTP(S) and TCP
• <your process here>
• Role is hosted on IIS
• HTTP(S)
• ASP.NET
• Fast CGI + PHP
Web RoleWorker Role
VM Instances• 3 copies of each VM instance are stored• OS updates and patches are applied automatically• Scale-up VM instance

Windows Azure StorageScalable, durable and available cloud storage
Accessible anywhere at anytime
Storage Abstractions• Blobs• Drives• Tables• Queues
• Every storage abstraction is accessible viao REST API (platform agnostic)o Windows Azure SDK Client Library
Blob Storage• Binary large object storage• Objects stored in containers• Block Blob
o Targeted at streaming workloads (limit 200GB)
• Page Blobo Targeted at random read/write workloads (limit 1TB)
• CDN Deliverable (26 locations)• Partitioned by Blob name
Drive Storage• Provides durable NTFS volumes for Windows Azure
applications to useo Read/Write 1:1o Read-only 1:N
• Use existing NTFS APIs to access Cloud Drive
Table Storage• No schema stored for a table (NoSQL)• Table = group of entities• Entity = key + name/value pairs• Partitioned by key• Scale out to billions of entities
Queue Storage• Simple message queue• Not transactional• Guarantee delivery / processing of messages
(two-step consumption)• Partitioned by Queue name
SQL AzureScalable relational database as a service
SQL Azure• A subset of full SQL Server 2008
o Goal is to achieve full symmetry with SQL Server
• Self-provisioning and capacity on demand• Automatically high available and fault-tolerant
o 3 replicas of each database
• Existing tools just work (via TDS protocol)• Federations (horizontal partitioning)• Automated maintenance
o Software updates, infrastructure and hardware
Reporting and Data Sync• SQL Azure Reporting
o SQL Server Reporting provided as a serviceo Integration with the existing tools
• SQL Azure Data Synco Geo-replicationo Sync between SQL Server and SQL Azure
Windows Azure AppFabricHigher application-level services in the cloud
Windows Azure AppFabric• Totally independent from other Azure services• Windows Azure AppFabric Service Bus
o Connectivity across network boundaries
• Windows Azure Access Controlo Single sign-on claims-based AuthN and AuthZ as a service
• Windows Azure Cachingo Distributed scalable in-memory caching service
