High Availability Overview

High availability refers to the uninterrupted availability of EDS components. In a EDS deployment, high availability eliminates a single point of failure and provides minimal service interruption in the event of failure. High availability deployments aim to minimize downtime and increase availability of a component.
The following features make the EDS components highly available:
  • Restart and failover. A component can restart on the same machine or on a backup machine after the process becomes unavailable.
  • Resilience. A EDS deployment can tolerate temporary failures. The EDS components are resilient to outage.
High availability features in EDS are available if you install EDS using custom installation mode on an Informatica domain high-availability setup.
When you plan a highly available EDS environment, you must also configure high availability for the EDS components and components that are external to EDS. Internal components include the Administrator Daemon, Apache ZooKeeper, the EDS Nodes, and the data flows. External components include Informatica domain and databases.
For information about Informatica domain high availability, see the Informatica Administrator Guide.
