IZ Ivan Z. Chief Technology Officer Small-Business (50 or fewer emp.) 12/21/2021 "Hazelcast is the one of the best tools for every day`s life" 5/5 What do you like best about Hazelcast Platform? Hazelcast first of all is a really great distributed data grid. You can use distributed collections out of the box like Map, Set, Queue for microservices replicas to share data or for caching purposes. Also, it is possible to take distributed locks to prevent doing the same work simultaneously. The Streaming framework Hazelcast Jet has many needful features and is very fast. Can be run separately from services or as a library. Supports automatic rebalancing and replication. Multiple network options to make a cluster such as multicasting or kubernetes support. Review collected by and hosted on G2.com. What do you dislike about Hazelcast Platform? It`s a little bit tricky to set up cluster in Kubernetes but it`s a matter of reading the documentation carefully. You should write serializers for objects yourself but it`s your payment for the size of the memory footprint of your cache. Poor search options in in-memory data structures. Review collected by and hosted on G2.com. Recommendations to others considering Hazelcast Platform: Great tool for distributed caches and for the stream processing Review collected by and hosted on G2.com. What problems is Hazelcast Platform solving and how is that benefiting you? Distributed cache, distributed locking for microservices architecture. Stream processing of the big data.

Review collected by and hosted on G2.com. What problems is Hazelcast Platform solving and how is that benefiting you? We needed Stream processing platform which allow to connect to Kafka and generate some output based on Python scripts provided by business analitycs.

Solutions Architect Mid-Market (51-1000 emp.) 11/19/2020 "Hazlecast IMDG helped us to reduce service transaction response times by an order of magnitude." 5/5 What do you like best about Hazelcast Platform?

Review collected by and hosted on G2.com. What do you dislike about Hazelcast Platform? At the time I was using this (2017), there weren't much documentation explaining the internal behavior, so we had to dig in to the source code. Review collected by and hosted on G2.com. Recommendations to others considering Hazelcast Platform: May be the stateful architectures that Hazelcast presents are not for every situation, as they are hard to manage (talking about DevOps). Use it when there is a dying need for performance. Review collected by and hosted on G2.com. What problems is Hazelcast Platform solving and how is that benefiting you? Hazlecast IMDG helped us to reduce service transaction response times by an order of magnitude, by allowing us to process at the data nodes, in memory. This is a huge cut down in network and disk I/O, when comparing to traditional architectures, where all the data is loaded to the service nodes. It also helped us increasing the number of CPUs available for a single transaction, thanks to it's distributed executor service.
