| <h1 class="first">Building Digital Integration Hub With Apache Ignite</h1> |
| <div class="col-sm-12 col-md-12 col-xs-12" style="padding:0 0 10px 0;"> |
| <div class="col-sm-6 col-md-6 col-xs-12" style="padding-left:0; padding-right:0"> |
| <p> |
| A digital integration hub (DIH) is an advanced platform architecture that aggregates multiple |
| back-end systems and databases into a low-latency and shared data store. Apache Ignite can |
| function as this high-performance shared store by caching and persisting data sets dispersed |
| across many disjointed external databases and systems. |
| </p> |
| |
| <p> |
| Applications typically access Ignite via an API service layer and get substantial performance |
| growth by requesting data from only this distributed store, which keeps all the records in |
| memory and offloads the back-end systems. |
| </p> |

| <img class="img-responsive" src="/images/digital-hub.png" width="440px" |
| style="float:right;"/> |
| </div> |
| </div> |
| |
| <p> |
| The primary purpose of Ignite as a DIH component is: |
| </p> |
| <ul class="page-list"> |
| <li>to enable implementations of large-scale and high-throughput architectures that prevent the back-end |
| systems from getting overwhelmed with excessive workloads</li> |
| <li>to avoid complex integrations between the back-end databases and the front-end API services</li> |
| </ul> |
| |
| <div class="page-heading">Synchronization of Apache Ignite and Back-End Systems</div> |
| <p> |
| Ignite, as the high-performance data store, needs to be synchronized with the back-end databases via |
| streaming, event-based, change data capture (CDC), or other techniques. |
| </p> |
| |
| <p> |
| Ignite provides the <code>CacheStore</code> interface for uni-directional synchronization between an |
| Ignite cluster and an external store supporting relational databases and some NoSQL stores. The interface |
| allows Ignite to write-through or write-behind all the changes to the backend-systems automatically. |
| It also includes transactions - Ignite coordinates and commits a transaction across its in-memory |
| cluster as well as an external transactional database. |
| </p> |
| |
| <p> |
| For bi-directional synchronization, you can consider various streaming, CDC, and event-based technologies. |
| For instance, Kafka, Spark, and Debezium are widely used to keep Ignite in sync with other databases. |
| </p> |
| |
| <div class="page-heading">Real-Time Analytics</div> |
| |
| <p> |
| Although real-time analytics is not a defining characteristic of digital integration hub architectures, |
| in some situations, you can end up consolidating operational and analytical data silos in Apache Ignite. |
| If this happens, you can tap into Ignite SQL, compute, and machine learning capabilities for real-time |
| analytics needs. |
