<div dir="ltr">Hi there.<div style>I am dealing with large amount of legacy application(MediaWiki, Joomla, ...) running on openstack. I am looking for the best way to improve high availability of my instances. All applications are not designed for fail(Non-Cloud-Ready Apps). So, what is the best way of improving HA on my non-clustered instances(Stateful Instances)?</div>
<div style>Thanks in advance.</div></div>
