Apache Ignite 2.1 - A Leap from In-Memory to Memory-Centric Architecture

By Denis Magda | May 12, 2017

The power and beauty of in-memory computing projects is that they truly do what they state -- deliver outstanding performance improvements by moving data closer to the CPU, using RAM as a storage and spreading the data sets out across a cluster of machines relying on horizontal scalability.

However, there is an unspoken side of the story. No matter how fast a platform is, we do not want to lose the data and encounter cluster restarts or other outages. To guarantee this we need to somehow make data persistent on the disk.

Apache Ignite: Build Cloud Ready Applications Today!

By Turik Campbell | May 02, 2017

All applications fundamentally are comprised of computing instructions and data the instructions utilize to solve a problem. These applications are high performant when computing instructions and data are distributed among available computing resources. A ‘cloud ready’ application should be able to:

  • Massively parallelize compute instructions.
  • Massively parallelize data.
  • Scale automatically as hardware resources are introduced into the network.
All of these features and more are provided by Apache Ignite’s in memory computing platform.

How Apache Ignite Processes Geographically Distributed Transactions

By Yakov Zhdanov | July 22, 2015

Imagine a bank offering variety of services to its customers. The customers of the bank are located in different geo-zones (regions), and most of the operations performed by a customer are zone-local, like ATM withdrawals or bill payments... However, some operations, such as wire transfers for example, may affect customers across different zones. Cross-zone operations are not as frequent, but nevertheless need to be supported in a transactional fashion as well.
