<div dir="ltr">Hi there.<div style>I am baffling between Cloudstack and Openstack to select. My Datacenter has more than 10 legacy application, which need to be run on top of the best matched CMP(Cloud Management Platform). I am search a lot and I select openStack and CloudStack at the end. But, I can not make a final decision about these two CMPs. I don't want to make any change to my legacy application codebase. So, my exact concern is: "How legacy applications can be run on OpenStack without any HA and resiliancy problems?" As we know cloud-ready applications are fully awared from underlying infrastucture, but what about non-cloud-ready apps(Legacy Applications)?</div>
<div style>CloudStack is DC virtualization cloud solution(Vcloud Like Cloud Solution) that handle all of the HA and resiliancy in the infrastructure layer, but the paradigm in openStack is infrastructure provisioning(AWS like cloud), which the HA problems shoud be addressed in application layer.<br>
</div><div style><div>So at general, how openStack support legacy applications to run without any HA problems?</div></div><div style>Thanks in advance.</div></div>
