What is the cloud?

An approach to computing that’s about internet scale and connecting to a variety of devices and endpoints

What is a Cloud Service?

A collection of related service roles

Web Role Worker Role

What Can It Run?

General Rule

Choice of Language

Choice of Frameworks

If it runs in Windows it can run as a Cloud Service

C#, VB, C++, Java, PHP, Node.js, Phython, etc.

.NET, ExpressJS, Rails, Zend, etc.

Web Role

All features of a worker role + IIS 7, 7.5 or IIS 8.0*ASP.NET 3.5 SP1, 4.0 or 4.5* – 64bitHostsWebforms or MVCFastCGI applications (e.g. PHP)Multiple Websites

Http(s)Web/Worker HybridCan optionally implement RoleEntryPoint *for Windows Server

2012

Worker Role Patterns

Queue Polling WorkerPoll and Pop Messages within while(true) loopE.g. Map/Reduce pattern, background image processing

Listening Worker RoleCreate TcpListener or WCF Service HostE.g. Run a .NET SMTP server or WCF Service

External Process Worker RoleOnStart or Run method executes Process.Start()Startup Task installs or executes background/foreground processCustom Role Entry Point (executable or .Net assembly)E.g. Run a database server, web server, distributed cache

Role Lifecycle

All roles may extend RoleEntryPointRoles report status via RoleEnvironment

METHODS EVENTS STATUS

Roles and Instances

At runtime each Role will execute on one or more instances A role instance is a set of code, configuration, and local data, deployed in a dedicated VM

Roles are defined in a Hosted ServiceA role definition specifies:Virtual machine sizeCommunication endpointsLocal storage resourcesetc.

Web Role 1

Web & Worker roles

Applications are specifically developed for Windows Azure Web roles, Worker roles and storage

Windows Azure applications can be run in a development environment

Pay per role instance Two instances required for 99.95% SLA

Add and remove instances based on demand Load balancing is automatically configured

Choose your instance sizeCompute Instance Size CPU Memory

Extra Small Shared 768 MB

Small 1 1.75 GB

Medium 2 3.5 GB

Large 4 7 GB

Extra Large 8 14 GB

A6 4 28 GB

A7 8 56 GB

Each instance is deployed in its own VM You can use RDP to access the VM

Cost is based on deployed instance sizes Charged even if the instance is not running

Remember the SLA requires at least two instances per role

Web Role 1

The developer builds the application

Configuration data values can be updated on the live system

The binaries and definition (csdef) file are zipped intoservice package file

Update & Fault Domains

Windows Azure distributes instances across multiple Update Domains to support in-place upgrades One domain is updated at a time

Supports application and Windows Azure OS updates Service remains running with reduced capacity

Similar concept used to support Windows Azure datacentre hardware failures Instances are distributed across multiple fault domains

A single failure will allow service to remain running

Staging and production

A service can be deployed to staging, tested and “moved” to production by swapping the VIP

A service upgrade can be deployed to staging and then swapped to the production environment During the swap the current production environment is “moved” to staging

Storage

Local storage can be allocated on an instance bases All Web and Worker roles are stateless so local storage should only be

used for caching

Persistent storage is managed through BLOBs

NTFS VHD drive can be stored in blobs and attached to instances Tables Queues SQL Azure

Storage access

Blobs, tables and queues are accessible via URLs Accessible via Representational State Transfer (REST) APIs

Uses HTTP methods : POST, GET, PUT and DELETE Requests are signed with the storage key

All Windows Azure storage can be accessed from anywhere
