IBM WebSphere Application Server Vs. Oracle WebLogic

Application Servers are classified based on following features:

  • Availability
  • Scalability
  • Clustering
  • Administration
  • Licensing cost


Below are the key differences between WebSphere Application Servers and WebLogic:

  • WebSphere tends to focus more on integration, connectivity and web services. WebLogic has focused more on emerging J2EE standards and ease of use.
  • WebLogic has default Transaction Attribute as “Supports” but WebSphere doesn’t have any default Transaction attribute.
  • WebLogic is easier to setup than WebSphere.
  • WebSphere clusters are more robust and efficient than Weblogic.
  • WebSphere Admin Console has more funcionalities to fine tune the applications running on it.
  • WebLogic is way ahead in implementing latest specifications.
  • WebSphere Admin Console provides the ability to administer webservers, but Weblogic does not have this feature.
  • WebSphere is available for more platforms than WebLogic (e.g. IBM z/OS).
  • WebSphere has all IBM product stack to back it up.
  • WebSphere has more integrated IDE’s.
  • WebSphere has a bigger community and IBM provides great support for it’s products.


Why to go for WebSphere Migration:

  • WebSphere is cheaper as compared to other application servers, it starts around 10k per CPU per year.
  • WebSphere console is easier to use as compared to WebLogic which has a lot of options to fill with.
  • WebSphere is actually a suite of products, it has Base, Express, Network Deployment and z/OS editions and WSAD as development tool.
  • If your application needs only support for JSP and Servlet, you may go for Express version. Complete J2EE specification comes with Base. If you are doing clustering and load balancing, you may go for Network Deployment.
  • If you are doing clustering, load balancing, deploying applications on multiple number of systems, then it is better to go for WebSphere products, it is like one-stop shop and you will get complete solution for your eBusiness applications.
  • WebSphere Admin Console is really good, full of funcionalities and very easy to maintain your applications, also maintains high level of security.
  • IBM MQ Series works better with WebSphere Application Server.
  • Highly critical applications in domains like BFS, Insurance etc. are recommended to go for IBM WebSphere Application Server.
