Standardized our Java estate and have reduced licensing costs while maintaining strong support
Azul Zulu's ability to allow us to standardize our Java estate on a single and well-supported platform stands out as one of its best features. This standardization simplifies our compliance audits and ensures all our applications receive timely security updates.Azul Zulu positively impacts our organization by providing a platform that allows us to standardize Java on a well-supported platform. Without the high cost associated with other proprietary vendors, Azul Zulu provides an excellent platform for running our applications.

Has enabled building responsive multi-threaded applications while supporting rapid deployment workflows
Microsoft .NET Framework has already made significant improvements by becoming open source. Many developers are contributing to Microsoft .NET Framework, not just Microsoft itself. They have ported it to many platforms and allow a healthy ecosystem of open source tools. They have moved from Visual SourceSafe to supporting Git with Microsoft Visual Studio. Their IDE, Visual Studio Code, is open source and multi-platform. There are many third-party tools available, including AI-based tools such as Cursor and Bolt, which are forks of Visual Studio Code. Based on my understanding, I don't have any suggestions for improvement as they are already doing an excellent job.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"We achieved specific outcomes from using Azul Zulu by reducing our Java licensing and support costs by approximately 70% when compared to our previous Oracle contract."
"We've had no issues with stability."
"The solution is user-friendly and straightforward."
"Our solution should work for roughly 50,000 users every day."
"The most valuable features are the Domain Controller and the WBFS Manager."
"Using this framework has enabled us to create services out of things we used to do manually, making our lives easier and increasing productivity as well."
"The new .NET Core has those middlewares, which are awesome from a security standpoint. With the old Framework or the newer Framework, middleware is basically an event pipeline. You configure and register it, and it handles things centrally. A simple example is logging. With the old Framework, you needed to try/catch blocks everywhere. Here, you configure the logging handler once, and it captures exceptions across the application. I really like the middleware pattern."
"In my opinion, the best thing about Microsoft .NET is the fully featured framework. It provides most of the things which a normal developer requires of any application out of the box."
"The most valuable feature of Microsoft .NET Framework is debugging."
"Basically, .NET is simply is the easiest programming language to use, based on my experience."
 

Cons

"It needs a better update daemon. At this time the process is manual and could be an issue on multiple desktop deployments."
"Improvements for Azul Zulu could include more automated tools for unused code visibility integrated directly into the standard portal to help further optimize our cloud footprints."
"They should have more training materials available that are specific to .NET. We spend a lot of money training our engineers."
"One thing that could be improved is the tooling and IDE for .NET in non-Windows environments like Mac."
"The product’s reliability needs improvement."
"I would like more web integration."
"The .NET open source community is very small and it would be nice if it were larger."
"The initial setup is complex."
"Difficult to scale this product for large organizations."
"In the next release, I am looking for more advanced technologies such as socket communication and enhanced features like realtime chat with the clients."
 

Pricing and Cost Advice

Information not available
"Microsoft .NET Framework is licensed under the Windows License."
"Considering the bigger picture, opting for the Microsoft ecosystem can be beneficial and it is priced well. When relying on entirely open-source solutions, you may encounter challenges associated with dealing with multiple vendors and potentially compromised security measures. However, it is important to note that Microsoft could enhance its performance when it comes to addressing critical security concerns."
"Microsoft .NET Framework is free of cost."
"The product’s pricing is a bit high."
"If you want to develop an enterprise-level application, you have to purchase the enterprise-level development license."
"We have an annual license, and we pay extra for extended support."
"In the interim, there's no need to purchase videos for viewing. Microsoft has made significant moves in the .NET space, starting with their response in Visual Studio Code and now providing Visual Studio entirely for free. This is a notable shift from the past when we used to pay substantial amounts for technical subscriptions. Previously, a group of ten developers could cost several thousand dollars annually for licensing. However, the current trend is to offer these tools for free to maintain their dominance in the developer market. The market dynamics have changed, and now developers can freely download Visual Studio, making it a preferred choice over other paid options."
"The support is an extra cost when purchasing the license. The price of the solution is overall reasonable and paid annually or every three years. Additionally, they have a monthly license. The cost is approximately $1,000 per user."
