Agenda Windows Azure An existing application with some problems Windows Azure SQL Azure Blob storage AppFabric service bus What to remember? Resources Q&A

Windows Azure

Definition of cloud (NIST) On-demand self service Standardized access Location independant resource pooling Rapid elasticity Pay per use

IT as a Service Private(On-Premise)Infrastructure (as a Service) Platform Storage Server HW Networking Servers Databases Virtualization Runtimes Applications Security & Integration Storage Server HW Networking Servers Databases Virtualization Runtimes Applications Security & Integration Storage Server HW Networking Servers Databases Virtualization Runtimes Applications Security & Integration You manage Managed by vendor You manage

The Windows Azure Platform Windows Azure SQL Azure Windows Azure platform AppFabric Microsoft Codename “Dallas” Microsoft Codename “Sydney”

Windows Azure Flexible application hosting Lights-out service management Provide code & service model, hit ENTER Storage at massive scale Blobs, tables, queues

Windows Azure

Storage options Blobs, tables, queues Windows Azure Drive (a.k.a. XDrive) Virtual NTFS volume that can be mounted.vhd format Use existing NTFS API’s Easier migration Stored on blob storage provides quick mount/unmount in other VM

SQL Azure Relational database as a service Highly available, automatically maintained Extension of the SQL Server Data Platform

SQL Azure Relational database, provided as a service Highly symmetrical development and tooling experience (use TDS protocol and T-SQL) Highly scaled out, on commodity hardware Built on the SQL Server technology foundation High availability, DB provisioning, and DB management are provided by the service

Windows Azure AppFabric Secure connections between services Across organizational boundaries Claims-based access control

Service Bus Overview

Windows Azure AppFabric - Service Bus Securely connect applications Over the internet Across any network topology (= across firewalls!) Across organizational boundaries Primary application patterns Eventing: Notify applications and/or devices Service Remoting: Securely project on-premises services out to the cloud Tunneling: App-to-app communication with NAT/Firewall traversal

Microsoft Codename “Dallas” Content brokerage and discovery platform Available as a CTP

Microsoft Codename “Sydney” - Connectivity

An existing application

Time Tracker Originated from the ASP.NET starter kit Small modifications: List of projects from internal billing system Time registration can have an attachment

TimeTracker – On-premise

Time Tracker There are some problems with it... Running on 2 web servers that are > 2 years old, nearing EOL Looking to buy new hardware Looking to deploy the application in a cloud Spikes near the end of each month, reducing performance Looking to buy additional hardware Looking to deploy the application in the cloud They do have this “seamless scaling” thing, right?

Workload Patterns Optimal for Cloud Usage Compute Time Average Inactivity Period “On and Off “ On & off workloads (e.g. batch job) Over provisioned capacity is wasted Time to market can be cumbersome Compute Time “Unpredictable Bursting“ Average Usage Unexpected/unplanned peak in demand Sudden spike impacts performance Can’t over provision for extreme cases Average Usage Compute Time “Growing Fast“ Successful services needs to grow/scale Keeping up w/ growth is big IT challenge Complex lead time for deployment Compute Time Average Usage “Predictable Bursting“ Services with micro seasonality trends Peaks due to periodic increased demand IT complexity and wasted capacity

Challenges Security? Forms based Claims based (AppFabric access control service) Availability & scalability out-of-the-box Still keep session state in mind Specify “upgrade domains” Logging & tracing System.Diagnostics.Trace Performance counters All stored on blob storage, not real-time! Operating system Windows Azure Cloud OS 1.0 – 1.1 – x.x See MSDN for patches and hotfixes in each OS version New cost model Pay-per-use Allow for scale-up and scale-down

TimeTracker on steroids! Our company decided to go for Windows Azure New migration track started Learn about Windows Azure Support deployment on Windows Azure Store data in SQL Azure Store attachments on blob storage Somehow connect with the billing system to get a list of project names Deploy

Support deployment on Windows Azure Convert the TimeTracker solution to a Cloud Service solution Make sure it can be packaged for deployment Make sure it runs on Development Fabric Requirements: IIS7 Visual Studio Windows Azure Tools for Microsoft Visual Studio Windows Azure SDK (shipped with the above)

Windows Azure Tools for Microsoft Visual Studio Get them on

Store data in SQL Azure There is a database on-premise in SQL Server Schema should be migrated Data should be migrated Requirements: Native SQL client SQL Management Studio

Store attachments on blob storage Attachments currently stored on the web server Windows Azure server storage not guaranteed to survive There’s an option for that......but it will still fail in some situations Ideal candidate: blob storage Requirements: Windows Azure SDK A tool to browse storage and see if it works

Tools to see if it works CloudBerryLab Explorer Azure Storage Explorer Online Visual Studio 2010 tools

Connect with the billing system List of projects comes from on-premise billing system TimeTracker will be in the cloud Requirements: Expose the billing system to the Internet Connect to it

Service Bus Overview

Connect with the billing system List of projects comes from on-premise billing system TimeTracker will be in the cloud Communication will happen over the AppFabric service bus Requirements: Visual Studio AppFabric SDK

Using AppFabric service bus

Another option… Billing system WCF configuration was changed If that’s not possible: PortBridge to the rescue!
