Distributed caching has reduced latency and now supports real-time stream processing
I think there are areas where Hazelcast Platform can improve, such as simplifying the cluster topology and sizing rules because they are still somewhat complex for someone new to Hazelcast. Understanding how the cluster topology forms and sizing rules work, such as partition balancing and traffic routing, should be much simpler. If one node has less RAM or a slightly slower CPU, it creates a cluster-wide performance bottleneck, which is critical, especially with transactional systems. Even though Hazelcast Platform has proven to be better, there can still be bottlenecks if the cluster topology and data partitioning are not easily understood. I also think that object handling and streamlined serialization should be prioritized; using standard Java serialization can be extremely slow. Providing native ultra-fast binary serialization out of the box, without requiring developers to write custom adapters, would be a significant improvement. It would be great if there were ready-to-use adapters for streamlined serialization and object handling.

Easy to install, very light, extremely fast, and provides direct access to the pipeline
The programmability is fun to use. I get direct access to the pipeline. I use it to correct a few things that our clients and servers don't like. So I do some on-the-fly corrections and a little hacking, and it works better. The tool is really easy to install, very light, and extremely fast. It requires low maintenance. I'm quite pleased with the product. It is easy to learn the product. It's all documented properly. The person who wants to learn the tool must know how to deal with such products. However, it is relatively simple. It's running well in our organization, and nobody needs to touch it. We haven't really touched any configuration in over a year as it's still working great. It has been running my same VCL code ever since initial deployment. It has been running stable since, apart from some minor optimizations here and there.

What is your experience regarding pricing and costs for Varnish Enterprise?
My experience with pricing, setup cost, and licensing is difficult as some clients do not want to pay so much.

I think Varnish Enterprise can be improved as the prices can be cheaper. Besides the price, I do not think there is anything else that could be better.
What is your primary use case for Varnish Enterprise?
My main use case for Varnish Enterprise is mostly cache. When I say mostly cache, I mean we get directly into Varnish and we edit the rules with VCL files.
