Description
The documentation has some references in regards of the term HA:
1) 2.7.3. External databases installation.
An external database installation is suitable for production use where high availability (HA) is a requirement or you plan to reuse your own database.
2) Chapter 10. Configuring an external MySQL database.
To configure an external MySQL database for High Availability (HA), perform the steps outlined in the following sections:
3) 8.1. High Availability template.
Before deploying the HA template, you must deploy and configure the external databases, and configure them in a HA configuration with a load-balanced endpoint.
Remarks:
A) Clarification on HA term and supportability:
- In 2) (supported configuration) "to configure an external MySQL database for High Availability (HA)" explains how to configure 1 database for HA. What does mean HA in this scenario?
- In 3) (tech preview configuration) "configure them in a HA configuration with a load-balanced endpoint." refers to a load-balanced endpoint for the database.
I think would be helpful to clarify what HA refers in every scenario since the configuration in 2) is supported and in 3) is not (tech preview).
B) Clarification on "Chapter 10" vs HA templates:
- The HA templates are tech preview, however according to 2) it is feasible to externalise MySQL (or PostgreSQL) with the amp.yml template so would be in the end the same result.
