Configuring an on-prem instance to connect to COD

You can configure an on-prem instance or node to connect to the Cloudera Operational Database (COD) deployed on an AWS, Azure, or GCP environment to run applications using Apache HBase Java API or the Apache Phoenix thick JDBC driver. When configuring a node, you have to configure a DNS and Kerberos

In COD, by default, your database is not accessible to the public internet due to security groups on the subnets of the VPC in which the database is deployed and the ingress rules of the VPC itself. Configuring an on-prem instance correctly can run applications using the Apache HBase Java API or the Apache Phoenix thick JDBC driver.

Ensure that the following prerequisites are met before connecting the on-prem instance to the COD.

  • You have the required permission to log into the COD on AWS, Azure, or GCP configured with CDP.
  • You have the required permission to launch EC2 nodes in your AWS account.
  • You have a basic understanding of the VPC and subnets created for use with CDP.
