How to make your IO-intensive MSSQL workloads highly available?

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.

New High Availability features for MSSQL in Windows Azure

Microsoft announces new features for its cloud answer to Amazon EC2 – Windows Azure. While Azure is far away from what giant EC2 has to offer we need to keep in mind that Microsoft is not trying to solve all the problems in the world (unlike EC2 because they can), but only trying to concentrate on making their platform (OS and Virtualization) as well as applications to remain relevant in this rapidly occurring transformation of technologies and workloads into the cloud as well as maturity of progress on the open source side.

Catch all(…) For high-availability in the cloud

Prerequisitehttp://docs.aws.amazon.com/AWSEC2/latest/UserGuide/using-regions-availability-zones.html

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
