Fast distributed storage and compute

Low-Latency Storage

When speed, scalability, and continuous processing are the core requirements for deployment.

For mission-critical, high-performance applications at speed, scale, and with continuous processing

Hazelcast connects a set of networked/clustered computers to pool together their random access memory (RAM) and CPU power to let applications share data structures and run parallelized workloads in the cluster.

The primary advantage is speed, which has become critical in an environment with billions of mobile, IoT devices and other sources continuously streaming data. With all relevant information in RAM, there is no need to traverse a network to remote storage for transaction processing. The difference in speed is significant – minutes vs. sub-millisecond response times for complex transactions done millions of times per second.

Hazelcast Low-Latency Storage Features

High-Density Memory Store

Enables the largest data sets to run efficiently in a high-performance cluster across your most popular data APIs. Certified for use with Intel Optane DC Persistent Memory for RAM speeds at higher densities and lower cost.

Tiered Storage

Combine the speed of RAM with the cost-effective scale of disks/SSDs to store more data used as reference data for enriching data streams, or as a low-latency data mart for downstream analytics.

Management Center

Provides a comprehensive view of all cluster activity, along with configurable watermarks for alerts through a web-based user interface and cluster-wide JMX and REST APIs.

Hot Restart Store

Whether the restart is a planned shutdown or a sudden cluster-wide crash, Hot Restart Store allows full recovery to the previous state of configuration and cluster data. Certified for use with Intel Optane DC Persistent Memory for 2.5X faster restarts than with SSDs.

Rolling Upgrade

Upgrades cluster nodes and versions without service interruption.

Security Suite

Provides standards-based Java Authentication and Authorization Service (JAAS) and interoperable encryption, authentication, and access control checks to mission-critical applications.

WAN Replication

Synchronize multiple Hazelcast clusters in different datacenters for disaster recovery with a low recovery point objective (RPO), or geographic locality. Supports active-active and active-passive topologies.

Blue/Green Deployments

Switch between alternate clusters on demand in a blue/green deployment strategy, where an offline, updated cluster (the “green” cluster) is enabled and clients are redirected to that cluster. Should a problem arise, clients can be directed back to the original live (“blue”) cluster.

Automatic Disaster Recovery for Clients

Clients can be configured to automatically failover to a disaster recovery cluster to maintain a low recovery time objective (RTO), as part of your disaster recovery strategy.

Enterprise PAAS Deployment Environments

Enables your applications to run in the most popular enterprise container management environments, Pivotal Cloud Foundry and OpenShift Container Platform.

World-Class Service

24×7 service and support with a one-hour service-level agreement, as well as maintenance and hot patch fixes.

Hazelcast Distributed Storage and Compute Applied to Fraud Detection

Competent fraud detection systems can help organizations gain a clearer view of entities, relationships, and hidden patterns as they deal with financial crimes, including payment card fraud, anti-money laundering and anti-terrorist financing. Hazelcast can store account details, recent transaction history and scoring all in one place for powerful, comprehensive checks, live within the request. Short SLAs measured in milliseconds means that these checks must be done very fast. If high-speed fraud detection is your concern, Hazelcast is a perfect fit.

Transforming and Simplifying Public Sector IT

The UK’s largest Internet of Things (IoT) network serves more than 200,000 homes with a system that allows users to remotely control their heating and hot water temperature from their mobile device or on the internet. This completes 20,000 writes per second in a 20-node Hazelcast cluster with plenty of spare capacity and an average latency of under 1 millisecond.

Hazelcast is used as the back-end infrastructure for many IoT deployments. Everything from in-home thermostats and lighting systems to industrial sensors, such as smart meters and in-store e-Commerce systems.
