This topic describes the deployment architecture of Dremio on Amazon Elastic Container Service for Kubernetes (EKS).
High availability is dependent on the Kubernetes infrastructure. If any of the Kubernetes pods go down for any reason, Kubernetes brings up another pod to replace the pod that is out of commission.
Load balancing distributes the workload from Dremio’s web (UI and REST) client and ODBC/JDBC clients. All web and ODBC/JDBC clients connect to a single endpoint (load balancer) rather than directly to an individual pod. These connections are then distributed across available coordinator (master-coordinator and slave-coordinator) pods.
