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.

Caching static commerce pages has boosted customer checkout speed and reduced infrastructure costs
The most valuable aspect is that it is very easy to handle Varnish Cloud TTLs, and Varnish Cloud works very well. I can store any amount of data, and I also appreciate the control over Varnish Cloud, such as with the tags, where I can tag certain areas of caching. I believe the best features Varnish Cloud offers are its management capabilities and the control over Varnish Cloud itself. I appreciate the management interface and how all the management policies are very nicely handled, along with very productive responses. The tool works very well, and I have been seeing the same Varnish technology for the last 11 to 12 years, and I'm continuously working on it. Varnish Cloud is impacting our end users positively, basically in terms of their profit growth because the profit is coming from saving the infrastructure load and also serving the customer website very fast. It is giving a faster load speed which helped customers purchase things faster and finish the checkout journey as soon as possible, and it has also helped the website vendor reduce the cost of infrastructure.

Quotes from Members

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

Pros

"There have definitely been a lot more latency reductions and better SLA performance since using Hazelcast Platform, resulting in faster time to market overall for new features and capabilities because the architecture has become simpler."
"Varnish Cloud is impacting our end users positively, basically in terms of their profit growth because the profit is coming from saving the infrastructure load and also serving the customer website very fast."
 

Cons

"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."
"I would rate Varnish Cloud an eight on a scale of one to ten because I think the capability to manage dynamic content or compatibility with dynamic content is lacking."
