What does Avance HA do?
Like everRun, Avance HA also offers continuous processing capabilities. It supports this type of processing in a different way, however.
Avance harnesses together two systems using a modified Xen hypervisor and powerful monitoring and automation software. Applications are loaded into a virtual machine that executes on both physical host systems. Data and applications are synchronized between the two host servers continuously. If one fails, the other simply keeps on processing. The end users don't see the failure.
What does this announcement mean?
everRun became a Stratus product when the company acquired Marathon Technologies in September 2012. Critics pointed out that the company then had two products that used different approaches and solved the same problem. They pointed out that it would be very difficult for Stratus to explain which product customers should use and why.
While this acquisition created a little bit of a conundrum for Stratus. It now had two software-based continuous processing solutions, each having unique features, but both offering very powerful tools to support continuous processing environments.
The challenge was how those features could be combined in the same product. The next issue was how to create a migration path for customers using those two different approaches that would lead to a new unified product without causing problems for the customers.
It is clear that after looking at the problem since September 2012, Stratus developed a new product having the best features of each of the older product. Furthermore, this was a time that Stratus could move to a newer, more manageable, more scalable virtual machine technology.
While the company tells me that this release is designed to deliver "mainframe levels of availability" to its enterprise customers, I have no problem visualizing Stratus offering the same capability to service providers allowing them to offer "continuous processing clouds" at some time in the future.
If your company has applications that simply can't be seen to fail, Stratus has several options that would be well worth the effort to examine.
