Applications such as SQL Server and others are being moved to the cloud on a daily basis to take advantage of both the flexibility and cost savings of moving up to that type of an environment. The issue with moving to the cloud is that you still have to worry about availability. Just because it is up in the cloud doesn’t mean it’s going to be up one hundred percent of the time.

See the video for illustration of two different instances up in the cloud. Generally this would not be a configuration that you could use to set up a cluster and ensure high availability for your application mainly because there is no shared storage between these two machines. With SIOS technology, we provide the real-time block level data replication software that enables you to keep the data between these two systems in sync and useable as a part of a cluster configuration. Should the primary system fail, the application will fail over to the target or the standby system and it will come online with a real-time copy of the data just sitting there waiting to take over.

By adopting a SANLess cluster up in the cloud, you can now take advantage of flexibility in the cost savings and not having to sacrifice availability.
