Data Lake HA
Enterprise Data Lake offers HA and fault resilience for most components inside the Data Lake whereas Light duty Data Lake does not provide HA.
Cloudera Public Cloud offers the following types of Data Lakes depending on the scale and production-level requirements for the workload:
- Light Duty Data Lake
- This Data Lake is not highly available and is not suitable for production workloads. However, you can use it for demonstration and proof of concept (POC) purposes, and during early evaluation phases.
- Enterprise Data Lakes
- Enterprise Data Lake offers HA and fault resilience and the configuration enables zero downtime upgrade (ZDU) for most of the components inside the Data Lake. Enterprise Data Lakes are available as of 7.2.17 for new environments only.
Availability of services depends on the node being repaired. With the exception of the gateway and auxiliary nodes, the remaining groups can typically survive a single node failure without affecting the workloads or UI/API access.
In the event of a gateway node failure on an Enterprise Data Lake, the load-balancer seamlessly routes to the other gateway node.
