Configuring SSL for a Standard HTAP Instance

Secure Socket Layer (SSL) is an encryption-based Internet security protocol for establishing secure links between a server and a client. It provides privacy, authentication, and integrity to Internet communications. SSL:

  • Authenticates users and servers, ensuring that data is sent to correct clients and servers.
  • Encrypts data to prevent data theft.
  • Ensures data integrity during transmission.

By default, SSL is enabled for new HTAP instances. Enabling SSL increases the network connection response time and CPU usage, and you are advised to evaluate the impact on service performance before enabling SSL.

You can use a client to connect to your HTAP instance through a non-SSL or SSL connection.

  • If SSL is enabled, you can connect to a database using an SSL connection, which is more secure.
  • If SSL is disabled, you can connect to a database using a non-SSL connection.

Enabling or disabling SSL will reboot the instance immediately. During the reboot, the instance is unavailable. Rebooting an instance will clear its cache. To prevent traffic congestion during peak hours, you are advised to reboot it during off-peak hours.
