In this blog, author Dmitriy Setrakyan defines Ignite by answering several "Is Ignite a ...?" questions.
Using Java and .NET Apps to Connect to an Apache Ignite ClusterBy Akmal Chaudhri | September 08, 2017
In many organizations, different departments and teams work with different programming languages and frameworks. However, there may be a need for a common storage format to allow various tools to access the same data. Apache Ignite provides the flexibility for development teams to continue working with their favorite programming languages and tools and have the ability to work with the same data in the cluster.
Apache Ignite - In Memory Performance with Durability of DiskBy Dmitriy Setrakyan | September 07, 2017
Starting with 2.1 release, Apache Ignite has become one of a very few in-memory computing systems that provides its own distributed persistence layer.

So, what makes Ignite data storage unique?

Apache Ignite 2.1 - A Leap from In-Memory to Memory-Centric ArchitectureBy 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.

How Apache Ignite Processes Geographically Distributed TransactionsBy 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.
