What is the difference between Oracle OpenWorld 2012 and Olympics?

by Roman Kharkovski

Last week I attended Oracle OpenWorld conference in San Francisco, CA. One thing that struck me was the number of claims about imaginary records broken by Oracle – starting with the Larry’s keynote on Sunday and continuing every day on technical tracks. Here are few things that were announced by Oracle in the past week:

  • New version of the Exadata machine X3-2 (shipment date is unknown)
  • New version of the Exalogic machine X3-2 (shipment date is unknown)
  • Oracle Database and Java public and private cloud services (available now)
  • Oracle Database 12c pre-announcement (to be shipped “sometime in 2013”)

Read analysis of these Oracle announcements in the full blog post here: What is the difference between Oracle OpenWorld 2012 and Olympics?.

Oracle Exalogic – the emperor has no clothes! (part 2)

by Roman Kharkovski

(Click on the image below to read the full article)

In this post, I compare IBM PureApplication System to Oracle Exalogic. Trying to compare IBM PureApplication System to Oracle Exalogic is like comparing latest generation digital SLR camera to the film camera. They both serve similar purpose, and in the end – you “might” be able to get similar results, but with huge differences in cost per picture, convenience, level of skills, and amount of time involved.

It is not just about engineering a system. It is about the expertise to make the most of it.

by Roman Kharkovski

In my last post I have discussed Oracle Exalogic as the emperor who has no clothes. In that post I have discussed what Oracle Exalogic was not. That was easy. But the more interesting question is this – what should the next generation of systems really be? What do enterprises need from their systems today? Oracle talks about engineered systems, “optimized for performance levels that are unmatched in the industry”. Having worked with hundreds of large and small clients over the years I think what is needed today goes further than that. It goes well beyond merely engineering a fast system to run a vendor’s software stack. Performance is important, but it is not even the most important factor. Enterprises I work with are yearning for a whole new approach to computing.

IBM and Oracle software licensing and support in virtualized private cloud environments

by Roman Kharkovski

Oracle license and support policy does not allow companies to take advantage of the server partitioning and imposes high costs practically negating many benefits of virtualization. IBM embraced virtualization years ago and provides support and flexible sub-capacity pricing for its customers. In 2010 Larry Ellison decided that “clouds are ok”. Since that time Oracle embraced both virtualization and private clouds at the “buzzword level”, yet Oracle license and support policy has not caught up yet and punishes Oracle customers who are using virtualized environments. How can there be such a disconnect between the marketing machine and the company legal and support policy?

WebSphere 2012 trends and directions

by Roman Kharkovski


Jerry Cuomo is IBM Fellow and WebSphere CTO. In the past few years he posted his thoughts on technology trends for the year and described how they were going to be implemented in WebSphere products by IBM. This year, as always, is very exciting – perhaps more so than any other year in the past (isn’t it always the case?).

Here are his Top 10 Trends for 2012 (= top 2012 WebSphere trends):

  1. Mobile for Enterprises
  2. PaaS Plus
  3. DevOps
  4. Cloud Benchmarks
  5. 20/20 Analytics
  6. Workload Integrated Systems
  7. DataPower-as-a-Service
  8. Internet Scale Computing
  9. Business API Management
  10. Social Business

Please read full article in Jerry’s “Trends for 2012″ blog post.

Comparison of automation tools for large scale WebSphere, WebLogic and JBoss (and other vendor servers) topologies

by Roman Kharkovski

What does Electric Tea Kettle have to do with IT automation? Clue – this has nothing to do with the fact that most IT departments have both – the Kettle(s) and IT.

Comparison of IBM and Oracle public cloud offerings (SaaS, PaaS, IaaS)

by Roman Kharkovski

In my earlier post I have compared IBM and Oracle tools for creating and managing private clouds. In this article I would like to review and compare public cloud capabilities from IBM and Oracle. Read the full article posted here: Comparison of IBM and Oracle public cloud offerings.

Comparison of two private cloud tools from IBM and Oracle

by Roman Kharkovski


The task of deploying a software stack as a VM image onto a virtualized server has historically been a highly labor-intensive task. For instance, one has to first deploy and configure the OS along with all requisite patches. After that, the administrator has to install and configure the application server and all its constituent components (e.g. HTTP server, etc.) as well as patches and other fixes. For applications requiring a database, that becomes yet another piece of middleware that needs to be installed and configured. Then there is the application itself. Collectively, deploying and testing a complete application manually can require days or weeks to accomplish depending upon its overall complexity. In a private cloud environment, this kind of turnaround is untenable. The IBM Workload Deployer is specifically designed to address this problem. To the right is a screenshot of the pattern designer for IWD.

Following the IBM lead, Oracle is now starting to move in a similar direction. In June 2010 Oracle announced the Oracle Virtual Assembly Builder. This product provides provisioning of the virtual appliances into the Oracle VM environment. Other than overall lack of product maturity, there are number of significant limitations with the current version of the Oracle Virtual Assembly Builder product. Read full comparison in this blog entry: Comparison of two private cloud tools from IBM and Oracle.

When Oracle ships new version of the OVAB product, I will update my comparison, but for now this is the best I can do given current versions of both products.
