Microservices Architecture

This applies to: Visual Data Discovery

The Symphony platform is architected as a set of loosely-coupled Java microservices. Unlike traditional business intelligence software, which is deployed as a monolithic application, a microservices architecture allows for the following benefits:

• Faster deployment of new functionality

• Optimal resource management

• Faster recovery in some failure scenarios

• Greater deployment flexibility

Each Symphony microservice runs in its own Java Virtual Machine (JVM) to optimize memory allocation and runtime attributes to meet its function and load. A failure in one microservice does not take down all Symphony, and recovery is faster because only the failed microservice needs to restart. Deploying new functionality, such as an updated or custom data store connector, occurs by auto-discovery, and without requiring a server restart.

Separately, Symphony centralizes its metadata store in a relational database and includes an internal messaging queue. The communication protocols used by the microservices include WebSockets (for real-time bidirectional communication) and HTTP/S.
