As Amrith noted, Stratus is focusing on ways to run highly-available, legacy applications that are hosted on OpenStack.<br>

Hi Hossein,<br>
<br>
You can get HA on OpenStack for things like storage just as you would in<br>
your existing data center. Unless you are running some highly available or<br>
fault tolerant hardware in your data center, I believe you will see<br>
comparable reliability in an OpenStack cloud, at least with respect to<br>
computing.<br>
<br>
I am interpreting Jay's answer below to say that you can build additional<br>
availability through scale-out paradigms but that may be inconsistent with<br>
your desire to make no change to your applications.<br>
<br>
If what you are looking for is a fault tolerant offering in the OpenStack<br>
cloud, maybe you want to look at something like Stratus (I'm sure someone<br>
from Stratus can respond and tell you more).<br>

| Hi Hossein,<br>
|<br>
| The short answer is that the idea behind "legacy" applications -- i.e.<br>
| that applications should rely on infrastructure to handle reliability of<br>
| the application in a scale-up-only manner -- is not something that the<br>
| OpenStack platform really encourages.<br>
|<br>
| We encourage scale-out behaviour and application development methodologies<br>
| that give the scaling, reliability, and resiliency control to the<br>
| application deployer to implement as they see fits best their application.<br>
| It's not a one-size-fits-all world, and as such, there are plenty of<br>
| application architectures and deployment methodologies that are supported<br>
| in cloudy environments; OpenStack doesn't pick or choose one over another.<br>
|<br>
| Best,<br>
