  • General Windows Azure Best Practices :

    -> Understand Account Scalability targets.
    - Use multiple storage accounts to get more
    - Distribute your storage accounts across the region.

    -> Cache critical data sets
    - As a "backup" data set to fall back on
    - To get more request/sec than the account/partition target

    -> Distribute load over many partitions and avoid spikes
    - Avoid append/Pretend patterns

    -> Locate storage accounts close to compute/users

    -> Use HTTPS

    -> Optimize what you send and receive
    -Blobs: Range reads, Metadata, Head Requests
    -Tables: JSON vs AtomPub,Upsert,Merge,Projection<Point Queries
    -Queses: Update Message,Batch size

    ->Control Parallelism at the application layer
    -Unbounded Parallelism can lead to slow latency and throttleing

    -> Enable logging & Metrics
    - Can be done via REST, Client API or Portal
    - Enables clients to self diagnose issues, including performance related ones
    - Data can be automatically GC'd according to a user specified retention interval
    - Have longer retention for hourly metrics and shorter retention for minute metrics.

     -> To build resilient distributed system
    -Rely on caching
    * Caching layer with fail fast but cache updated in background

    -> Use storage Analysts to learn about your usage
    -understand limits of single storage account , partition
    -Avoid unnecessary round trips & bandwidth usage
    -continuously monitor for anomalies

    -> Efficient retries

     -> Exponential back-off for background job
    -Constant back-off for websites
    -Use secondary for higher availability

    Hope this helps!

    Regards.
