Noticeable Speed
Noticeable Speed

Anything less than a sub-microsecond response time, done millions of times per second, is of no value. Hazelcast IMDG handles it with ease.

Elastic Scalability
Elastic Scalability

Scale up to terabytes of RAM in moments, then scale down as resources are no longer required. This is the flexibility that will drive your success.


No one likes or needs an unstable system. With distributed caching and parallel processing, Hazelcast IMDG delivers a solution with zero downtime. That's right, zero.


Don't become another cautionary tale. Hazelcast offers world-class security management based on a constantly improving model. We worry about this so you don't have to.

In-Memory Data Grid

Technology that drives innovation across your entire production environment.

Technology that drives innovation across your entire production environment.

Hazelcast IMDG is easy to work with and brings a highly resilient and elastic memory resource to all of your applications. At its core, Hazelcast is one of the most widely adopted Open Source solutions, with tens of thousands of installed clusters and million of server starts per day. On top of this popular Open Source platform, Hazelcast IMDG Enterprise HD, Hazelcast IMDG Enterprise, and Hazelcast IMDG Professional Support offer licensed features for large scale deployments. Now you can free your data from slow, expensive, and hard-to-scale relational data sources. With Hazelcast IMDG, your database remains the system of record, but bottlenecks disappear.

Drive performance to new levels.


Reduction in time to accuracy

From minutes to seconds

1.2 microseconds

Max application latency

Improved user and customer experience

Exceed Expectations

Impress technical and business users (and your customers) with instant response times to complex event processing requirements.

Meet Burst Requirements

Millions of people or devices hitting your system at the same time, and all expecting an instant response? This is exactly what an IMDG is designed to handle, and Hazelcast is the industry leader for in-memory solutions.

Improved Performance

Scale and improve your performance elastically, reducing hardware requirements and driving operational  efficiency.

Reduce fraud risk while exceeding SLAs.


Complex transactions per second

Fraud detection in microseconds

Reduce Risk of Fraud

Run multiple (7+) fraud detection algorithms in the time it takes to swipe a card. And that’s just one example.

Exceed SLAs

IMDG caching enables you to comfortably exceed expectations associated with stringent SLA requirements.

Expand Transaction Limits

Faster processing = more transactions = more business. This also reduces risk of fraud and improves customer satisfaction.
