This blog provides high availability (HA) guidelines using group
replication architecture and deployment recommendations in MySQL,
based on our best practices.
Every architecture and deployment depends on the customer
requirements and application demands for high availability and
the estimated level of usage. For example, using high read or
high write applications, or both, with a need for 99.999%
Here, we give architecture and deployment recommendations along
with a technical overview for a solution that provides a high
level of high availability and assumes the usage of high
read/write applications (20k or more queries per second).
This architecture is composed of two main layers:
- Connection and distribution layer
- RDBMS …
