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

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

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
