Magic Quadrant for Enterprise Application Platform as a Service http://

www.gartner.com/technology/reprints.do?id=1-1P502BX&ct=140108&st=sb Microsoft's offering, Windows Azure, has evolved into an environment that supports IaaS and PaaS models. As a result of adding full IaaS capabilities, as well as fleshing out its private cloud strategy, the vendor now provides the onramps that are making PaaS much more approachable for enterprises.

PaaS for the Modern Web

Paas is secureEnterprise Grade Availability with support for SSL and AD

PaaS is flexibleWeb hosting your way with choice of language, framework, database, and platform

PaaS is scalableScale out or up in seconds on a Load Balanced, Always up to date, Global Infrastructure

The Benefits of PaaS

Paas is cheaperReason: There’s less admin and management work to doBenefit: Organizations spend less supporting applications

PaaS is fasterReason: There’s less work for developers to doBenefit: Applications can go from idea to availability more quickly

PaaS is lower riskReason: The platform does more, leaving fewer opportunities for errorBenefit: Creating and running applications gets more reliable

PaaS is always up to dateReason: Runs on Windows server 2012.Benefit: Always patched. Always running latest versions of frameworks

Web Sites Features

Some misconceptionsWeb Sites is a frequently underestimated platform

Blogs & CMS’s

Only for startups

No logging or monitoring

Lacks on-premises integration

No middle tier

Start Simple

Get started with 10 free web sites

Create new sites in seconds

Easily manage and scale your sites

Automatic load balancing and shared storage across instances

Scale out or up to reserved instances for improved performance and scale

Code Smart

Use ASP.NET, ASP, PHP, or Node.js

SQL Azure or MySQL databases

Start with open source apps and frameworks

Develop with VS and WebMatrix (and Monaco!)

Supports any Web development tool on any platform (Windows, OSX, Linux)

Cdn

Access to other Azure Services

Caching

Media

Big data

Analytics

Rapid deployment for quick iteration

Integrated source control with Team Foundation Server (TFS) and Git

Built-in monitoring of perf and usage data

Quick access to request logs, failed requests diagnostics and diagnostics

Enterprise grade

High availability with SLA on reserve instances.A global network of data centers.Guaranteed SLA and 24/7 support.

Enterprise grade.

Load balanced Up to date Easily scale Economical

Architecture

How does Windows Azure websites work?Cloud first by design, but also available on premise.

SQL based configuration.

Dynamic provisioning of sites on demand.

Network-based storage (Azure xDrive, SMB, NAS, SAN).

Intelligent load balancing.

Load balanced by default

Traffic automatically load balanced across two or more servers.

Websites architectureAll DBs are running on SQL Azure.

Azure blobs as durable storage.

Windows Azure worker roles.

Monitor resources usage.

Dynamic web activation service.

W3WP.exe IIS application pool process.

Web Sites are not in IIS. They only are when a request comes

in!

Load balancer

Layers 1st layer: Windows Azure load balancer 2nd layer: IIS + ARR

ARR “Reverse proxy” Verifies hosting database (plans, quotas, …) Negotiates best node to run your site on Site not used much? Put it on a highly loaded machine

Project Kudu

“The engine behind git deployments on Windows Azure”

Open source (www.github.com/projectkudu/kudu)

Provides git deployments Provides builds Provides sandboxing Provides hosting

Scaling

Windows Azure is a scalable platformWhich allows you to add and remove resourcesWith flexible pricing

Scaling is manual, based on your decisions

Understand elasticity

Flexible

Understand elasticity You can automate scaling:

Service Management API PowerShell Writing your own code

3rd party tools Or use Autoscaling Application Block

Scalability Scaling up and scaling out

What does scaling mean for my apps?It depends… but some general practices apply.• Capacity plan• Proper decomposition of system• Stateless design• Scale at all layers• Throttling
