Faster portals have transformed daily customer report handling and streamlined workload management

December 12, 2025
Review provided by PeerSpot

What is our primary use case?

My main use case for OpenJDK Java is basically all Java-related applications, such as opening our customers' GUI portal, SMA, and RMA. Those are rating management-related applications, customer data management, and also the voice and SMS call flow configurations. For all those, I need to open the GUI via port forwarding, and those applications all run in OpenJDK Java in my organization.

A quick, specific example of how I use OpenJDK Java in one of those applications is that for daily work, I need to extract some particular reports from a customer. For those cases, I always use OpenJDK Java only. I open it via a Java GUI and using OpenJDK Java and those cosmote things, my daily work happens. Every application our customer runs uses this.

What is most valuable?

OpenJDK Java offers many best features. The most significant feature is that it is completely free and open source because it is available under the General Public License with the classpath exception. That means it can be used, modified, and distributed freely for both personal and commercial purposes. Additionally, Java features and enhancements are developed openly with the OpenJDK project via the JDK Enhancement Proposal, which is one of the best things. The portability and flexibility is also one of the key things.

The portability and flexibility of OpenJDK Java have helped me because the open-source nature and wide community support mean that OpenJDK Java is available across a broader range of platforms, including Linux on various architectures, Windows, and macOS. It can be customized accordingly to specific infrastructure needs.

OpenJDK Java has positively impacted my organization because we were using some older Java version previously, but after using OpenJDK Java, things got very much better, and nowadays, no issues happen while opening customer GUI and managing customer data. Time management and workload management have become very balanced after using this.

Time management and workload have improved significantly since using OpenJDK Java. Previously, other versions of Java were being used, including Oracle Java. At that time, a GUI used to open in ten to fifteen minutes, but now, within one to two minutes, those are opening. That is the positive part, and other improvements are also there.

What needs improvement?

OpenJDK Java can be improved in some areas. The regular releases and security updates need to be more frequently available in OpenJDK Java, which is not currently the case. Additionally, the compiler optimizations should be enhanced. The significant work going on to enhance is the JIT compilers. Recent examples include improvements to scalar replacement. These things make applications run smoother and faster, and those enhancements can also be done. The modularization can be done to improve it as well. Those are my concerns.

I would also add one more point about the needed improvements, which is the optimization of application code for efficiency through data structures. That can also be a point.

For how long have I used the solution?

I have been using OpenJDK Java for about four years.

What do I think about the stability of the solution?

OpenJDK Java seems very stable.

What do I think about the scalability of the solution?

In terms of scalability, OpenJDK Java seems fine. It is good.

How are customer service and support?

I have interacted with customer support, and they seem very good.

I will rate customer support ten out of ten because they are very supportive.

How would you rate customer service and support?

Positive

Which solution did I use previously and why did I switch?

I previously used another version of Java, version three point zero, which was very laggy because in the toughest situations, sometimes it took a long time to open those applications. Those impacted our customers as well as our revenue.

What was our ROI?

I have seen a return on investment. In terms of workload management, the time consumed got very much less after using OpenJDK Java. Customer GUIs and customer portals are opening very smoothly with no lag. Previously, we were using some other Java versions where too much lag was also there. Due to this, some customer operations and change windows expired, and we got some escalations, but from the day we started using OpenJDK Java, we did not get any complaints for it.

What's my experience with pricing, setup cost, and licensing?

My experience with pricing, setup cost, and licensing is very much fine with this, as I have already discussed.

Which other solutions did I evaluate?

Before choosing OpenJDK Java, I did not evaluate other options.

What other advice do I have?

My advice to others looking into using OpenJDK Java is to use it for at least a few months, and then you will get the difference. You will see the better things that have come in this Java version, and you will absolutely get it. Then you will never stop using it. I think I have shared enough information on OpenJDK Java. I found this interview quite good. I rate this review at nine out of ten.

Cross-platform backend services have accelerated certificate APIs and simplified developer work

December 03, 2025
Review from a verified AWS customer

What is our primary use case?

My main use case for OpenJDK Java is for backend services.

A specific example of how I use OpenJDK Java in my work is for the backend server for textual service certificates.

The kind of backend systems or applications I support with OpenJDK Java is an API that's mostly for developers who communicate through our API.

What is most valuable?

In my opinion, the best feature that OpenJDK Java offers is that it's a cross-platform solution you can use on any operating system.

The way that helps my team or projects is that it definitely makes our backend developers' lives easier. It's easy to develop and faster to deploy.

OpenJDK Java is well supported, and it really helps our developers.

OpenJDK Java has positively impacted my organization because if developers can deliver work faster, it has of course positively impacted the company.

What needs improvement?

Unfortunately, I cannot answer how OpenJDK Java can be improved. The only thing I can say is that perhaps it could provide more functions or available libraries.

The improvements OpenJDK Java needs are mostly just the functions and drivers that need to be set up.

For how long have I used the solution?

I have been using OpenJDK Java for four years.

What do I think about the stability of the solution?

In my experience, OpenJDK Java is stable.

What do I think about the scalability of the solution?

The scalability of OpenJDK Java is good so far.

What's my experience with pricing, setup cost, and licensing?

My experience with pricing, setup cost, and licensing is that I cannot speak to it because I have not experienced anything.

Which other solutions did I evaluate?

I have not evaluated any other options before choosing OpenJDK Java.

What other advice do I have?

I think everything is clear regarding how I use OpenJDK Java in my setup, so I have nothing other than that to add.

I would rate OpenJDK Java an eight out of ten.

I chose eight out of ten because, as I mentioned, I believe it is a strong solution.

I do not have any advice to give to others looking into using OpenJDK Java.

My company does not have a business relationship with this vendor other than being a customer.

The overall rating for this review is eight out of ten.

Migration has cut licensing costs and supports long-term api development and maintenance

December 02, 2025
Review from a verified AWS customer

What is our primary use case?

OpenJDK Java is used for Spring Boot APIs written using versions 21 to 24. A specific example of how OpenJDK Java is used with those Spring Boot APIs is that it is built on top of OpenJDK, so it is used to compile and run the APIs.

What is most valuable?

The best feature OpenJDK Java offers is that it is free software with no licensing fees.

The free licensing aspect helps the organization by impacting the budget and helping save on costs.

OpenJDK Java has positively impacted the organization because, since Java was taken over by Oracle, it became very difficult to secure the license, which was heavy on the cost. OpenJDK Java helped to save on that, and it is very similar to the Oracle JDK.

Almost a million dollars in cost savings have been realized since switching to OpenJDK Java.

What needs improvement?

OpenJDK Java performs well overall. However, OpenJDK Java could be improved in terms of memory performance, and threads could be better optimized.

For how long have I used the solution?

OpenJDK Java has been in use for 10 years.

What do I think about the stability of the solution?

OpenJDK Java is stable.

What do I think about the scalability of the solution?

No scalability issues have been observed with OpenJDK Java; it scales very well.

How are customer service and support?

The customer support for OpenJDK Java is very good with no problems.

How would you rate customer service and support?

Which solution did I use previously and why did I switch?

Before using OpenJDK Java, Oracle Java was used, but the switch was necessary because of the licensing cost.

How was the initial setup?

OpenJDK Java was purchased through the AWS Marketplace.

What was our ROI?

A return on investment has been realized, specifically in terms of money saved and time saved.

Approximately two hours daily have been saved in terms of maintenance since implementing OpenJDK Java, and in terms of project estimation, about four to six story points are saved.

What's my experience with pricing, setup cost, and licensing?

The experience with pricing, setup cost, and licensing has been very positive; the licensing was free, and the cost was negligible.

Which other solutions did I evaluate?

Before choosing OpenJDK Java, Java was required, so OpenJDK Java was the only other option available.

What other advice do I have?

OpenJDK Java is license-free for this use case.

OpenJDK Java is very performant, and memory issues are not commonly observed.

The advice to others looking into using OpenJDK Java is that if there is a need to save on the licensing cost and benefit from the advantages of Oracle Java, OpenJDK Java is recommended. This review has been rated 10 out of 10.

Which deployment model are you using for this solution?

Hybrid Cloud

If public cloud, private cloud, or hybrid cloud, which cloud provider do you use?
