tMIX10 – Day Three – Microsoft Silverlight and Windows Azure – A Match Made for the Web

Design Patterns

  • Hosting Silverlight in the Cloud
    • ASP.NET website hosted in Windows Azure
    • XAP file hosted on the website, used in the browser
      • Like an on-premises website, but has the flexibility of the Cloud
  • Shared Storage Signature for WIndows Azure Storage
    • Use the FromConfigurationSetting static method from the CloudStorageAccount class
    • Create a SharedAccessPolicy to define the policy for how the key will be shared.

Tips and Tricks

  • Silverlight
    • Use .NET Framework 3.5 in the Cloud
    • ASP.NET MVC is recommended as the WebRole
    • Make sure you Install Static Content support in IIS
    • Smooth Streaming not supported yet on Windows Azure
  • WCF
    • For load-balanced considerations
      • Load balanced endpoint flags
      • Consider connections timeouts (1 minute)
        • Asynchronous patterns works well
      • PollingDuplexHttpBinding expects affinity
        • In this case you’ll need to store the client state yourself
    • Different port mappings in the cloud
      • Quick: Patch port mappings into auto-generated service reference
  • Other Windows Azure Platform Services
    • SQL Azure
      • SQL Database in the cloud
      • Provisioned on-demand with high-availability
      • No physical administration required
    • Windows Azure Platform AppFabric
      • Service Bus
        • Connect Asynchronously between on-premise services and cloud services
          • Firewall transversal with message rendezvous
      • Access Control
        • STS in the Cloud

MIX10 – Day One – Designing and Delivering Scalable and Resilient Web Services

Ron Jacobs – Sr. Technical Evangelist – Microsoft

http://blogs.msdn.com/rjacobs

“Do the simplest thing that will possibly Work”

Scalability – Able to support the required quality of Service as the system load increases – Wiktionary

Typical Web Architecture

  • Users
    • Need a to get routed to same machine (ex. stick sessions)
  • Web Tier
  • Data Tier

Problem: “It’s simple but isn’t scalable”

Solutions:

  • Keep your data near where she’s processing
    • Ex. Cache
    • Cache is scoped to machines / process
      • machine dies
      • processes recycle
    • Cache memory
    • Imagine “What if?”
      • You could have as much cache as you wanted?
      • You could share giant parts of your applications?
      • What about if it was free?
    • You have: Windows Server App Fabric

What is AppFabric Caching?

  • An explicit, distributed, in-memory application cache for all kinds of data
    • Caching clients can be across machines or processes
    • Clients access the cache as if it was a large single cache
      • This creates a Unified Cache View.
    • Doesn’t need to be recycled or recompiled when some other process or machine is added

Data Distribution

  • Scale on Data Size – more machines => more memory to cache
  • Scale on Cache Throughput – more machines => keys are distributed across machines => better throughput
  • It’s better to scale with several machines that with a large machine with lots of memory, because the throughput

Take control over AppFabric Cache using the DataCacheFactory class.

Steps:

  1. Configure the AppFabric Configuration Store
  2. Copy the Client Dlls
  3. Update the Web.Config to host the AppFabric Caching

Supports:

  • Clients: .NET 4.0 and 3.5
  • Cache Server: .NET 4.0

Administration

  • PowerShell commands
    • get-CacheHelp
  • Performance Counters

AppFabric Cache Codeplex Tool – http://mdcadmintool.codeplex.com

Security

  • Domain-Based Security Option
    • Domain Account / Load Account based Authentication
    • Only authorized servers can join the clusters

AppFabric Caching Logical Hierarchy

Machine –> Cache Host –> Named Caches –> Regions –> Cache Items –> Objects

  • Host
    • Physical processes hosting AppFabric Caching instance
  • Named Caches
    • Can span across machines
  • Regions
    • Groups that you want to treat together

Types of Data

  • Reference Data
    • Primary Read Only
    • ex. Catalog Data
  • Activity Data
    • Read-Write not shared
    • Ex. Shopping cart
  • Resource Data
    • Read-write and Shared
    • Ex. Auction Data / Seat Assignment

Reference Data

  • Performance
    • Catalog data doesn’t change often
    • Unnecessary network cost to access from different machines
    • Solution – Local Cache
  • Bulk Get
    • Bulk Fetch from region
      • 200-300k of calls per second
      • better performance

Activity Data

  • Session Integration
    • Just define SessionState to Custom mode and use the “SessopmStoreProvider” to use AppFabric Caching
  • Availability
    • It’s possible to define AppFabric Caching to use High Availability and replicate the cached data

Resource Data

  • Optimistic Locking
    • GetCacheItem returns a version object
    • Every update to an object internally increments it’s version
    • Supply the version obtained along with the Put/Remove
  • Pessimistic Locking
    • GetAndLock return a lock handle
    • Doesn’t lock the Get

Resource and Activity Data

  • Get Cache Events Notifications
  • Register on any client to notify changes
  • Batched Notifications

Scalable Notifications

  • Register the notification for a specific key
  • Map keys to partition
  • Poll Required nodes
  • Nodes return list of changes

How to get this

  • Use at the Web Platform Installer, on the Options to enable the Enterprise Tab
  • Afterwards just select the Enterprise tab and install it
