[Online] Hazelcast: In-Memory Data Grid Without Black Magic

  • May 7, 2015 · 8:00 PM
  • This location is shown only to members

In-Memory Data Grids (or IMDGs in short) have historically been the exclusive domain of large Investment Banks and proprietary solutions such as Oracle Coherence, VMWare Pivotal Gemfire and Software AG Terracotta. Hazelcast provides the leading open source alternative to these solutions, and is helping to support the democratization of Data Grid technology across a much wider range of vertical industries including telco, gaming, travel, ecommerce, software, life sciences, health care and many more.

What is an In-Memory Data Grid?
An In-Memory Data Grid is data management software that enables:

* Scale-out Computing: every node adds their CPU and RAM to the cluster, which can be used by all nodes
* Resilience: nodes can fail randomly without data loss while minimizing performance impact to running applications
* Programming Model: a way for developers to easily program the cluster of machines as if it were a single machine
* Fast, Big Data: it enables very large data sets to be manipulated in main memory
* Dynamic Scalability: nodes (computers) can dynamically join the other computers in a grid (cluster)
* Elastic Main Memory: every node adds their RAM to the cluster’s memory pool

In-Memory Data Grids are often used with Databases in order to improve performance of applications, to distribute data across servers, clusters and geographies and to manage very large data sets or very high data ingest rates.

No prior knowledge of IMDBs or Hazelcast required!

    1h is just not enough for material and discussion we probably should shoot for 2h next time

      Thanks Denis. Online session has pros and cons. It's technically impossible to fit everything into just one session. That is why I have started Hazelcast user group as separate entity.
