Isolation: Security or noisy neighbor?

The topic of isolation is often challenging to compartmentalize. Typically, companies will think about isolation through a security and compliance lens where isolation is used to create boundaries between resources to limit any exposure to cross-tenant access. This is a key area of focus for isolation. However, isolation is also implemented as part of addressing noisy neighbor and performance concerns. This is another reason data for tenants may be isolated. For the scope of this paper, we will be including coverage of both items with more emphasis on the security dimensions of this problem.
