What is a cloud?

•You already know that, next slide please.

What is a cloud?

What is a cloud?

Scenarios

•Rapid growth•Unpredictable usage

▫tickets, emergency systems, marketing•Predictable usage

▫e-commerce, test results•Temporary usage

▫events

Where is Azure?

•„Host your webpages, deploy ready apps” – SaaS▫manage nothing

•„Host your applications” – PaaS▫manage app and data

•„Host your infrastructure” – IaaS (?)▫manage app, data, middleware, OS… (!)

What is Azure?

•Everything you will ever need

•Windows Azure •Windows Azure Fabric •SQL Azure •Live Services•SharePoint Services•Dynamics CRM Services

Environment

•Data Centers▫More than 10▫Less than 100

•2.3 * 109$ •30000 engineers

•$$$$$$$$$$$$

Basics

•The world is based on .NET▫ or is it not? Java, Python, PHP, Ruby…

•You need more power•You don’t need to know how does it work•Connect via WCF, SOAP, REST, …•Microsoft.WindowsAzure•Use PowerShell•Trust us!

Glossary

•Role▫app logic

•Storage▫queue, table, blob▫Azure Drive

NTFS mounted to a role up to 400 MB/s (+cache)

•SQL Azure▫replicas + load balancing

Glossary

•Fabric▫hardware abstraction▫scaling, load balancing

•AppFabric▫access control and more

•Management API

•Diagnostic API

Architecture

Web Role

•Hosts web application▫ASP.NET, ASP.NET MVC, WCF, FastCGI, …▫IIS – full configuration in XML▫automatic load balancing▫user front-end

Worker Role

•~= console application▫Run() ~= main()▫may execute any code, host database, etc.▫may work like a daemon process▫usually contains process logic

AppFabric

•PaaS level• integrates cloud apps with other apps•as for now – only Service Bus and Access

Control

AppFabric• Access Control

▫Single Sign-On▫Active Directory Federation Server▫Windows Live ID, Google, Yahoo!, Facebook…

• Service Bus▫secure communication▫hybrid topologies▫different protocols

• Cache▫ transparent for client, easy to manage,

nonexistent

Storage•Table

▫no constant schema▫scales over thousands of servers (partitioning

key)▫no relations, foreign keys, joins, aggregates▫LINQ, REST API▫indices on PK and RK▫timestamp – optimistic concurrency + ETAG▫entities up to 1MB, but they can have different

properties▫transactions within a partition

Storage• Blob

▫ no structure, serialized data, video, pictures, …▫ Block Blob – streamed data

Up to 200GB/blob, 4MB blocks▫ Page Blob – random access

Up to 1TB/blob▫ Put, Get, Delete, Copy, Snapshot, Lease▫ properties

• Drive▫ shared files, simple structure management▫ possible mounting of VHD with work environment▫ based on Page Blob

Storage•Queue

▫communication between roles, separation▫almost FIFO, one way

almost – messages may be processed many times so there is NO real order guarantee, possible

starvation etc.▫easy scaling▫free data transfer from roles to queues!▫up to 100TB, 8kB per message, saved for 7

days▫timeouts

Deployment

•Windows Azure▫IntelliTrace▫no debugging

•Azure Development Storage/Fabric▫95% compatibility with Azure (90% of AF

code)▫local development

•Separate configuration (no redeploying)•Deploy via Web, VisualStudio, PowerShell•Demo
