99.99% available ASP.NET and SQL Server Production Architecture for SaaS
You have a hot ASP.NET+SQL Server product, growing at thousand users per day and you have hit the limit of your own garage hosting capability. Now that you have enough VC money in your pocket, you are planning to go out and host on some real hosting facility, maybe a colocation or managed hosting. So, you are thinking, how to design a physical architecture that will ensure performance, scalability, security and availability of your product? How can you achieve four-nine (99.99%) availability?

So, you can take this production architecture as a very good candidate for Level 3 SaaS:
