You have your IO-intensive application on the backed powered by SSD (from FusionIO for example) and you do not want your IOPs to get cut by 50% or more by adding a HA solution, however on the back of your head you realize that HA is important considering that your business depends on this application.

In this post I would like to expose some of the pain points that you may be experiencing (certainly would like to hear more! If I didn’t cover them all) as you transition your Microsoft SQL based applications into the cloud.
You may already know that SIOS Technology Corp. recently announced DataKeeper Cloud Edition that enables native Microsoft SQL Failover Clustering in EC2 environment within a since Virtual Private Cloud (VPC) and between the Availability Zones (AZs).
Is it enough? Continue reading
