Active-Active Clusters
A place for everything, --especially xkoto’s GRIDSCALE database virtualization
Wednesday, December 17, 200802:20 pm EDT
Vertica’s founder, Mike Stonebraker, had some interesting observations about the database world, and more specifically Oracle, in this interview. As one of the industry’s pioneers, he takes some jabs at Oracle RAC and the company’s monolithic view of data, which he calls their “one size fits all” assertion. In the past, I have weighed in on the downsides of RAC’s shared everything approach, but I’ll let Mike’s observations on the inherent scalability limitations speak for me this time.
Clearly, one size does not fit all. For example, innovative Column databases such as Vertica have significant advantages in many of the analytics-heavy use cases that make them shine. Mainstream row-oriented databases are particularly useful for those relational join gymnastics required by reporting and decision support. Oracle’s Exadata, Microsoft’s DATAllegro, and IBM’s Balanced Warehouse advance the cause of data warehouse appliances. Each technology has its place—one size does not fit all.
There is also an important place for our GRIDSCALE database virtualization product. Today I was speaking to one of the world’s biggest ISVs in the telco OSS space, which is weighing how to address the need to improve database access for its data-intensive applications. This is that important place for xkoto’s GRIDSCALE database virtualization software. We see GRIDSCALE as the database “shim” that allows an application provider to turn its single instance database into an active/active database pool without a major coding exercise for the ISV. This way, the ISV can focus on its strengths and leverage xkoto’s strengths as a software appliance in its stack. A place for everything and everything in its place.

What is Database Virtualization
Tuesday, September 16, 200805:35 pm EDT
Recently I had the pleasure of speaking with Robin Bloor, leading technology analyst from Hurwitz and Associates, about database virtualization. We had a good discussion about the merits of grid and shared-nothing architectures as an alternative approach to traditional, tightly clustered solutions like Oracle RAC.

Red Hat on RAC
Tuesday, July 22, 200808:16 am EDT
Red Hat launched a promotion urging businesses to evaluate its clustering technology over Oracle RAC for high availability (HA) needs. The promotional video is worth watching. It explains how with RAC, costs for a basic two-node cluster can mount to $240,000. Yikes indeed.
At xkoto, we hear from customers who balk at the licensing costs of RAC. But we don’t believe yet another passive clustering solution is necessarily the answer. With database virtualization, you can rapidly provision systems on the fly, leverage existing hardware, and save on both storage and WAN costs. Watch our On Demand Webcast to find out how database virtualization compares to other traditional clustering approaches.
