  90. 90. Fabric<br />Fabric controller<br />Compute<br />Storage<br />The Fabric Controller communicates with every server within the Fabric. It manages Windows Azure, monitors every application, decides where new applications should run – optimizing hardware utilization.<br />Windows Azure Architecture<br />
  91. 91. The Fabric Controller automates load balancing and computes resource scaling<br />Security and Control Features include storage encryption, access authentication, and over-the-wire encryption using HTTPS. Industry certification is part of the Windows Azure roadmap.<br />Computation provides application scalability. Developers can build a combination of web and worker roles. Those roles can be replicated as needed to scale the applications and computational processing power.<br />Storage Services allow customers to scale to store large amounts of data – in any format – for any length of time, only paying for what they use or store.<br />Geographically distributed, state-of-the-art data centers host your applications and data, internet-accessible from everywhere you choose to allow.<br />Windows Azure Architecture<br />

  94. 94. Storage<br />GOAL:<br />SCALABLE, DURABLE STORAGE<br />Tables: simply structured data, accessed using ADO.NET Data Services<br />Queues: serially accessed messages or requests, allowing web-roles and worker-roles to interact<br />Blobs: large, unstructured data (audio, video, etc)<br />Windows Azure storage is an application managed by the Fabric Controller<br />Windows Azure applications can use native storage or SQL Azure<br />Application state is kept in storage services, so worker roles can replicate as needed<br />Windows Azure Architecture<br />
