Cross-platform backend services have accelerated certificate APIs and simplified developer work
Reviewed on Dec 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.
How are customer service and support?
The customer support for OpenJDK Java is good.
How would you rate customer service and support?
Which solution did I use previously and why did I switch?
I did not use a different solution before OpenJDK Java.
What about the implementation team?
I purchased OpenJDK Java through the AWS Marketplace as a company decision.
What was our ROI?
I have not seen a return on investment with OpenJDK Java.
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.

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