Betting on Database Virtualization
Friday, October 31, 200809:12 am EDT
I just returned from the annual IBM Information On Demand conference in Las Vegas where I was able to catch up with a number of our partners and customers - i.e. I was not spending time in the casinos! In my meetings with the top two hypervisor vendors, I was told that more and more customers are migrating their databases to virtual machines. This move is one that I and other virtualization watchers have expected as the inevitable act two, following the very successful initial value proposition of system consolidation. So the database virtualization train has left the station right? Well ... sort of…

RE: Rap on RAC
Monday, October 20, 200801:23 pm EDT
In Jeff Browning’s Oct. 15, 2008 post, ”To RAC or not to RAC (reprise)”, he compares some performance and cost metrics between a four node Oracle RAC cluster running on physical hardware, and a virtualized Oracle environment under VMware.
It’s not clear how Oracle was configured in the virtual environment, but straight off it’s not hard to compute the cost differences - Oracle RAC is not light on the IT budget. In a shared storage architecture, Oracle RAC costs go even higher if disaster recovery (DR) is factored in - add a replication solution like Oracle DataGuard, replicated SANs, and potentially big WAN pipes and the costs keep shooting up....

Database Virtualization for SQL Server
Tuesday, October 07, 200809:45 am EDT
Last week xkoto reached a major milestone with the launch of GRIDSCALE for Microsoft SQL Server. GRIDSCALE enables IT professionals to avoid the scalability limitations, technical complexity, and costs associated with traditional clustering, mirroring and replication solutions for SQL Server. Ariff Kassam, our CTO and co-founder, gave a presentation and demo of GRIDSCALE at last week’s live Webinar. In case you missed it, you can watch the recorded version anytime here.

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.

London Stock Exchange - “Highly Reliable Times”?
Tuesday, September 09, 200804:27 pm EDT
The outage at the London Stock Exchange Sept. 8, 2008 may have been triggered due to high trading volumes. Whatever the post-mortem analysis ends up uncovering, the result is another painful example of how fragile IT infrastructure can be and the damaging impact that can be inflicted…

Grid vs. Cloud Computing
Tuesday, September 02, 200809:53 am EDT
In Derrick Harris’ recent blog post, “Grid vs. Cloud vs. What Really Matters”, he makes some astute comments to de-hype some of the noise around cloud computing and grids. Recently I was speaking on yet another popular paradigm - virtualization - and I tried to demarcate where grids, clouds, and virtualization had their primary use cases and their boundaries. Sure enough, an IT vendor in the audience came up to me afterwards to assert that grid use cases went beyond the HPC fence I put around it. Fair comment, showing again that different models do overlap and more convergence is expected.
Case in point - Derrick also mentioned data virtualization vs. database virtualization…
