Commercial GlassFish Support Is Back – Adam Bien’s Interview with Steve Millidge

Adam Bien: What is the relation between C2B2 and GlassFish?
Steve Millidge: We've had a long history helping customers to use GlassFish in production environments. In fact my first ever conference speech in California was at Sun's CommunityOne conference on Monitoring and Tuning GlassFish back in 2009, so we go back a long way. We were Sun partners back then, promoting GlassFish, and our now Oracle Gold Partners. We have a number of customers we support on GlassFish and we also run the London GlassFish User group. With the announcement from Oracle we are now gearing up our effort to build up the community of contributors on the core GlassFish source to ensure a good response when bugs and patches are needed.

AB: What is C2B2's Commercial GlassFish support? What will a customer get for the money?
SM: We provide 24/7 operational support to customers deploying GlassFish in production.  Read the complete article here.

Expert GlassFish Support

  • Do you run mission critical Applications on GlassFish?
  • Do you wish there was somebody to turn to if you had GlassFish performance, GlassFish scalability or GlassFish availability problems?
  • Do you find it difficult to recruit GlassFish operations specialists with deep knowledge?

C2B2 provide expert GlassFish support services 24/7 to customers running mission critical GlassFish applications. Our GlassFish engineers provide 2nd and 3rd line expertise as backup to your GlassFish operations team. Our expert GlassFish consultants can login to your servers and assist with triage, remedial action and root cause analysis of GlassFish problems rapidly reducing diagnosis and fix times.

When combined with a support subscription from Oracle we can liaise with Oracle to isolate test cases and get a GlassFish patch if that is the root cause. We can also liaise with your GlassFish development teams to identify application problems and suggest application fixes to increase GlassFish availability, GlassFish scalability and GlassFish performance.

C2B2 offers Glassfish support by Steve Millidge

Oracle have just announced that commercial support for GlassFish 4 will not be available from Oracle. In light of this announcement I thought I would put together some thoughts about how I see this development.
I think the key word in this announcement is "commercial", nowhere does Oracle announce the "death of GlassFish" in contrary Oracle reaffirm;

GlassFish Server Open Source Edition continues to be the strategic foundation for Java EE reference implementation going forward. And for developers, updates will be delivered as needed to continue to deliver a great developer experience for GlassFish Server Open Source Edition so GlassFish is not about to go away soon. In a similar fashion RedHat do not provide commercial support for WildFly and only provide commercial support for JBoss EAP. Admittedly JBoss EAP and WildFly are much closer together than GlassFish and WebLogic but WildFly and JBoss EAP are absolutely NOT the same thing.
The key going forward to the viability of GlassFish as a production platform is how the GlassFish community develops;

  • How often does the community release binary builds?
  • How open is the community to bug fixes?
  • How much engineering resource does Oracle commit to GlassFish?

At this stage we just don't know the answers to these questions.

If the GlassFish open source project continues on it's current trajectory without a commercial support offering then I don't see much of a problem. Oracle just have to work harder to sell migration paths to WebLogic in the same way as RedHat have to sell migration paths from WildFly to JBoss EAP.

In the meantime  C2B2 continues to offer support for your operational JEE applications running on GlassFish and we will endeavour to work with the community to get any bugs fixed. The key difference is we can no longer back our Expert Support with a support contract from Oracle for patches and fixes for any release greater than 3.x. Read the complete article here.
