Should each web application have its own storage account?

I'm trying to get up-and-going with Windows Azure. I understand that I need to create a "Storage Account". However, what I'm confused about is, how I should set it up. For instance, my Azure subscription is set to my company name. I intend to have multiple ASP.NET web applications (web roles) associated with my subscription. Each web application will have its own database.

Should each web application have its own storage account? Or should only one storage account be used for all of my projects?

There's no one way to answer this, but here are some thoughts to help your decision:

• Each storage account is limited to 100TB. If you feel that you will push the limits of this across multiple websites, then create multiple storage accounts for sure.
• To make billing easier, I'd suggest separate storage accounts
• Storage accounts have an SLA of a few thousand transactions per second across the entire storage account. For performance purposes, it's probably better to have separate storage accounts
• Consider putting your diagnostic data in a separate storage account. This way, you can safely give your Storage Account key to a 3rd-party like ParaLeap (creators of AzureWatch) for monitoring your app, while not giving away the key to real customer data, for instance.
• If you need more than 5 storage accounts, you'll need to contact Customer Support to increase this number.
