| // (though there may be additional network bandwidth charges). |
| // Instances offer isolation: problems with databases in one instance |
| // will not affect other instances. However, within an instance |
| // databases can affect each other. For example, if one database in an |
| // instance receives a lot of requests and consumes most of the |
| // instance resources, fewer resources are available for other |
| // databases in that instance, and their performance may suffer. |
