This reviewer was offered a nominal incentive as thanks for completing this review. **Reviewed Date:** April 18, 2023 **What do you like best about Hazelcast Platform?** I love the small memory of the library I embedded (since I have many issues with the memory of my pc). It is also very fast and not complex at all and it saved my all my problems in the distributed systems for sure! **What do you dislike about Hazelcast Platform?** Nothing to share about this...I would say as a con that it takes a bit more time in order to coordinate yourself where and what is located **What problems is Hazelcast Platform solving and how is that benefiting you?** Solved my problems with my relational databases where I was struggling with the whole backend team in managing correctly our db ### 2. Hazelcast is the one of the best tools for every day`s life **Rating:** 5.0/5.0 stars **Reviewed by:** Ivan Z. | Chief Technology Officer, Small-Business (50 or fewer emp.) **Validated Reviewer:** Validated through LinkedIn **Incentivized:** This reviewer was offered a nominal gift card as thank you for completing this review. **Source: G2 invite:** Invitation from G2. This reviewer was offered a nominal gift card as thank you for completing this review. **Reviewed Date:** December 21, 2021 **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. **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. **Recommendations to others considering Hazelcast Platform:** Great tool for distributed caches and for the stream processing **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. ### 3. Simple and Powerful Stream Processing Engine **Rating:** 4.5/5.0 stars **Reviewed by:** Mateusz K. | Senior Developer, Enterprise (> 1000 emp.) **Current User:** The reviewer uploaded a screenshot or submitted the review in-app verifying them as current user. **Validated Reviewer:** Validated through LinkedIn **Source: Organic:** Organic review. This review was written entirely without invitation or incentive from G2, a seller, or an affiliate. **Reviewed Date:** January 26, 2021 At G2, we prefer fresh reviews and we like to follow up with reviewers. They may not have updated their review text, but have updated their review. **What do you like best about Hazelcast Platform?** Performance and how it is easy to start implementation. In-memory processing is great advantage, because of high availability. **What do you dislike about Hazelcast Platform?** Documentation is not as good as for Hazelcast IMDG and sometimes I do not know where I can find some information I am looking for. **What problems is Hazelcast Platform solving and how is that benefiting you?** We needed a stream processing platform which allows us to connect to Kafka and generate some output based on Python scripts provided by business analytics. Jet allowed us to get messages from Kafka, translate them, enrich with data from software based on another Hazelcast IMDG, execute Python scripts and generate expected output. ### 4. Hazlecast IMDG helped us to reduce service transaction response times by an order of magnitude. **Rating:** 5.0/5.0 stars **Reviewed by:** Tharanga H. | Solutions Architect, Mid-Market (51-1000 emp.) **Validated Reviewer:** Validated through LinkedIn **Incentivized:** This reviewer was offered a nominal gift card as thank you for completing this review. **Source: G2 invite:** Invitation from G2. This reviewer was offered a nominal gift card as thank you for completing this review. **Reviewed Date:** November 19, 2020 **What do you like best about Hazelcast Platform?** Hazlecast is great because it's distributed data-structures are extensions of commonly used java interfaces. Due to this our team was able to quickly grasp the framework, and implement our solution. **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. **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. **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.

This reviewer was offered a nominal gift card as thank you for completing this review. **Reviewed Date:** January 08, 2021 **What do you like best about Hazelcast Platform?** I like Hazelcast being configurable to auto back-up features of it. When one of your hazelcast instance is down, remaining instances in the cluster recovers those data from backup and continue working where it left. **What do you dislike about Hazelcast Platform?** I can't think of anything I don't like about Hazelcast IMDG, maybe the pricing would be the worst side of it. **Recommendations to others considering Hazelcast Platform:** I used Hazelcast embedded to the services. However, stand-alone usage of Hazelcast might provide a better/more sustainable cluster. **What problems is Hazelcast Platform solving and how is that benefiting you?** Hazelcast is solving our caching problem and fastens the data access time. It also makes it possible to spend less time on managing instances of cache. The instances can discover each other and communicate as default. ### 6.
