Hosting a Multi-Tenant Application in Windows Azurehttp://msdn.microsoft.com/en-us/library/ff966480.aspxpatterns & practices Windows Azure Guidance sitehttp://wag.codeplex.com/Two active instances for one role will guarantees 99.95% uptime - Meaning max downtime = 4 hours 22 minutes pr. yearWe recommend that you deploy at least two instances per role to ensure high availability in case one of the instances becomes unavailable. Doing so also enables coverage of the Windows Azure Compute SLA, which guarantees 99.95% uptime. For more information please visit http://go.microsoft.com/fwlink/?LinkID=202707.

Overview of Windows Azure Connecthttp://msdn.microsoft.com/en-us/library/gg432997.aspxhttp://www.microsoft.com/windowsazure/virtualnetwork/Windows Azure ConnectWindows Azure Connect provides a simple and easy-to-manage mechanism to setup IP-based network connectivity between on-premises and Windows Azure resources. This capability makes it easier for an organization to migrate their existing applications to the cloud by enabling direct IP-based network connectivity with their existing on-premises infrastructure. For example, a company can deploy a Windows Azure application that connects to an on-premises SQL Server database, or domain-join Windows Azure services to their Active Directory deployment. In addition, Windows Azure Connect makes it simple for developers to setup direct connectivity to their cloud-hosted virtual machines, enabling remote administration and troubleshooting using the same tools that they use for on-premises applications.Microsoft Sync Frameworkhttp://msdn.microsoft.com/en-us/sync/default.aspx - Homehttp://code.msdn.microsoft.com/sync – sampleshttp://blogs.msdn.com/b/sync/ - team blogVM Rolehttp://msdn.microsoft.com/en-us/library/gg465398.aspx
Key Benefits of the Service The benefits of using SQL Azure are manifold. These include manageability, high availability, scalability, a familiar development model, and a relational data model. Self-ManagingSQL Azure offers the scale and functionality of an enterprise data center without the administrative overheads that are associated with on-premise instances of SQL Server. This self-managing capability enables organizations to provision data services for applications throughout the enterprise without adding to the support burden of the central IT department or distracting technology-savvy employees from their core tasks in order to maintain a departmental database application.With SQL Azure, you can provision your data storage in minutes. This reduces the initial costs of data services by enabling you to provision only what you need. When your needs change, you can easily extend your cloud-based data storage to meet those needs.High AvailabilitySQL Azure is built on proven Windows Server and SQL Server technologies, and is flexible enough to cope with any variations in usage and load. The service replicates multiple redundant copies of your data to multiple physical servers to maintain data availability and business continuity. In the case of a hardware failure, SQL Azure provides automatic failover to optimize availability for your application.ScalabilityA key advantage of SQL Azure is the ease with which you can scale your solution. After partitioning your data, the service scales as your data grows. A pay-as-you-grow pricing model makes sure that you only pay for the storage that you use, so that you can also scale down the service when you do not need it.Familiar Development ModelWhen developers create on-premise applications that use SQL Server, they use client libraries that use the tabular data stream (TDS) protocol to communicate between client and server. SQL Azure provides the same TDS interface as SQL Server so that you can use the same tools and libraries to build client applications for data that is stored in SQL Azure. For more about TDS, see Network Protocols and TDS Endpoints. Relational Data ModelSQL Azure will seem very familiar to developers and administrators because data is stored in SQL Azure just like it is stored in SQL Server, by using Transact-SQL. Conceptually similar to an on-premise instance of SQL Server, a SQL Azure server is logical group of databases that acts as an authorization boundary. Within each SQL Azure server, you can create multiple databases that have tables, views, stored procedures, indices, and other familiar database objects. This data model makes good use of your existing relational database design and Transact-SQL programming skills, and simplifies the process of migrating existing on-premise database applications to SQL Azure. For more about Transact-SQL and its relationship to SQL Azure, see Transact-SQL Support (SQL Azure Database).SQL Azure servers and databases are virtual objects that do not correspond to physical servers and databases. By insulating you from the physical implementation, SQL Azure enables you to spend time on your database design.

Azure Storage is significantly cheaper and more scalable than SQL Azure. The downside is that you lose querying ability since only PartitionKey and RowKey are indexed. Consequently, you need to gauge the importance of cost effectiveness and indexing. In this particular case the ACID semantics of SQL Azure are not particularly important since the data is written by a single client.One strategy is to store your scaleout data in Azure Storage and keep an index to it in SQL Azure.

http://social.technet.microsoft.com/wiki/contents/articles/inside-sql-azure.aspx“At this time, although there are availability guarantees with SQL Azure, there are no performance guarantees. Part of the reason for this is the multitenant problem: many subscribers with their own SQL Azure databases share the same instance of SQL Server and the same computer, and it is impossible to predict the workload that each subscriber’s connections will be requesting. However, not having guarantees doesn’t mean that performance is not a critical aspect of the design of the SQL Azure infrastructure. SQL Azure provides load balancing services that evaluate the load on each machine in the data center. “

Threat Modeling Web Applications Step 1: Identify security objectives. Clear objectives help you to focus the threat modeling activity and determine how much effort to spend on subsequent steps. Step 2: Create an application overview. Itemizing your application's important characteristics and actors helps you to identify relevant threats during step 4. Step 3: Decompose your application. A detailed understanding of the mechanics of your application makes it easier for you to uncover more relevant and more detailed threats. Step 4: Identify threats. Use details from steps 2 and 3 to identify threats relevant to your application scenario and context. Step 5: Identify vulnerabilities. Review the layers of your application to identify weaknesses related to your threats. Use vulnerability categories to help you focus on those areas where mistakes are most often made.
Windows Azure Security Notes Tackling cloud security can be overwhelming without an approach. These notes summarize how we took a look at securing Web applications, web services, and data in the cloud. We basically started by mapping out common application scenarios. We then figured out a way to group threats and attacks into a set of common categories. These categories make it easy for us to analyze and inspect the various parts of an application and engineering decisions. Then we focused on finding common principles, patterns, and practices, while working with customers, field, product teams, and industry experts. 121 pages

Cloud Benefits - Real-world Performance Analysis For very limited service requests, Azure-based solution takes slightly longer time to response than self-hosted solution. When more service requests come in, response time of self-hosted solution’s longest transaction will be longer. Meanwhile, response time of Azure-based solution’s longest transaction looks comparatively steady. When service requests increase rapidly, transaction rates of self-hosted solution drops down very fast, meanwhile transaction rates of Azure-based solution looks comparatively better.
