Unmatched Speed
Unmatched Speed

If high throughput and low latency results in quantifiable value for you, Hazelcast gives you the performance to get the most out of your system.

Elastic Scalability
Elastic Scalability

Scale up quickly when your load spikes, then scale down as resources are no longer required. This flexibility lets you efficiently meet load demands.


You face huge opportunity costs when your high-speed systems are down. Hazelcast provides built-in business continuity capabilities to ensure your system keeps running.


Your high-speed systems have data that must be protected from unauthorized access. Hazelcast provides authentication, authorization, end encryption to secure your data.

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.
