Drools

As an open source rule engine and product suite, Drools is well suited for the small and middle scale business to manage and integrate the rules to build the rule-driven system which can process the business-critical data and events to produce the automated decision. It is better to use Drools in the well-secured environment (back-end behind the DMZ), not putting it on the customer-facing front or exposing it directly the to public where may bring direct security risk in the enterprise environment. Drools still needs a lot hardening on the security side.

WebSphere Application Server

Large scale apps, EJB applications, Enterprise suite apps are where WebSphere Application Server will be most suited. Apps which need large volume and complex memory management also opt for WebSphere Application Server over Jboss.Small scale web services and REST where highly scalable server is not needed, WebSphere Application Server falls back. Simple servers like Tomcat and Jboss take the edge for small apps.

Pros

Drools

  • We started using the Drools since its early open source version, now Drools has grown to one application suite. We are majorly using the rule engine core Expert. It is very well integrated with our corporate programming language standard - java.
  • We also use Fusion to write rules about events that occur over time, which enhance our capability of dealing with static data and dynamic events for some complex business environment. Also, we like the fact that Fusion fully implements all first-order logic operators, which helps us deal with CEP very well.
  • The new editor UI Guvnor has been improved a lot and the optimization module Solver does a good job to "compile" complex rule flows to gain more performance.

WebSphere Application Server

  • It works out of the box. Its basic functionality is all there and everything works with no adjustments.
  • The functionality is there for fine tuning, to allow applications to be easier to access and quicker with some tweaks, but again, these aren't necessary for basic running.

Cons

Drools

  • Fusion doesn't support persistence of working memory, which brings some extra high availability risk to our business.
  • Guvnor still has a lot room to be implemented, it is not so user-friendly for non-technical people, so a lot of business users complain it is hard to master.
  • Rule execution server doesn't even have JMX implemented, hard to be monitored.
  • Drools is still lacking support for key Web services standards.

WebSphere Application Server

  • Ease of use in terms of deployment, give simple interface to do simple stuff like Tomcat, JBoss or GlassFish.
  • Takes long time to start the server.
  • The Liferay wars need to be decorated and then deployed. Perhaps we could simplify that.
  • Some of the concepts are good for complexity that WAS can handle but could be simplified and better documented, like concepts of well and profile, context, etc.
  • A Liferay war file created using Liferay Developer studio runs fine in Tomcat, however that may not run in WAS 7.x because it needs to be decorated. I had one war for a Liferay portlet with a simple cron job, and had hard time running to WAS server. It was running on the latest free download done on my friends m/c. Other times I have seen that there are issues running a war file that runs on Tomcat but runs on WAS after lot of customization for WAS.
  • The corporations like this however, the product may need better vibrant community of users where issues can be discussed.

WebSphere Application Server is used across our organization. Most projects use this for Java products and applications. Being robust and scalable makes it even more usable. We love using WebSphere Application Server due to its configuration management ability made simple and vast across all java related parameters. It is dependent on the features and upgrades and IBM releases some great upgrades to WebSphere Application Server.

Deploys fairly quick enough and like the roll-out update feature decreasing the downtime and also plays well with other integration tools as well.

IBM was quick to respond when we had an issue with our specific infrastructure. We raised a PMR, which they picked up quickly and updated us about every step of the way. We had an appropriate fix for quite a business critical issue within a fortnight, which was impressive!

Alternatives Considered

Drools

OpenRules provides the non-technical Excel way for a business user to easily modify and manage the rules. Sometimes we found Drools is a little bit overkill for some small and quick projects and we found Roolie is a not bad option as Drools alternative.

WebSphere Application Server

WAS is an IBM product and gels with IBM database product. So, we have decided to go with IBM WAS. WAS supports more data sources than Oracle web logic. So, ideally it can be used with multiple databases.

Return on Investment

Drools

  • The IT department quickly adopted Drools as it is a very good java-based rule engine, which saves a lot of time to meet the project timeline and balanced our business requirements.
  • Recently we start considering the OpenRules, which may be more business user-friendly.
