Hazelcast Cloud is an enterprise-grade in-memory computing platform deployed and managed by the Hazelcast CloudOps team. The service
is powered by Hazelcast IMDG Enterprise HD and leverages widely adopted technologies, such as Docker and Kubernetes, to provide dynamic orchestration and containerization. Hazelcast Cloud supports applications developed in some of the most common languages, including Java, Node.js, Python. Go, and .NET.
Hazelcast Cloud delivers enterprise-grade Hazelcast software in the cloud, deployed as a fully managed service. Leveraging over a decade of experience and best practices, Hazelcast Cloud delivers a high-throughput, low-latency service that scales to your needs while remaining simple to deploy. If you’re considering moving to the Cloud, or are looking for an easy ramp on deploying in-memory technology, this white paper on migrating in-memory to the cloud is an informative and helpful resource.
Setting up servers and configuring software can get in the way of the problems you are trying to solve. With Hazelcast Cloud we take all of those pain points away.
Watch this webinar to learn how you can instantly fire up and then work with Hazelcast Cloud from anywhere in the world. With our auto-generated client stubs for Java, Go, Node.js, Python and .NET, we can have you connected and coding in less than a minute!

This performance benchmark compares Redis Open Source 5.0.3 vs Hazelcast IMDG Enterprise 3.12. The purpose is to reproduce the low thread count benchmark conducted by Redis Labs in 2018, correcting for deficiencies in the Redis benchmark.
The things we changed were:
Hazelcast Enterprise 3.12 was slightly faster than Redis.
We would also draw your attention to our previous benchmarks which have consistently found Hazelcast faster than Redis:
3 members (1 member per machine)
<?xml version=”1.0” encoding=”UTF-8”?>
<port port-count=”200” auto-increment=”true”>5701</
<!-- Add the member IP addresses here -->
<native-memory allocator-type=”POOLED” enabled=”true”>
<size unit=”GIGABYTES” value=”30”/>
No additional configuration in redis.conf file. System adjusted as per Redis process output suggestions:

RadarGun 3.0.0 with modifications to support Redis.
Number of threads per client
Number of objects
Command line used
dist.sh -c <benchmark_xml_above> -t -m <master_ip>:2103 server1 server2
server3 client1 client2 client3
In order to provide an apples to apples comparison, we needed to run tests for both products using the same tool – RadarGun. However, RadarGun didn’t have capabilities for the setup that was presented by RedisLabs’ benchmark.
We implemented the support for all of the missing pieces, namely:
The source code of the modifications can be found in the following GitHub repository: https://github.com/hazelcast/radargun/tree/redis_benchmark. We hope to push these changes to the official RadarGun repository.
From the charts, we see that Redis with Lettuce client performed ~612 000 operations per second, whereas Hazelcast IMDG Enterprise did ~636 000 operations per second.
