Now, if you like it and wanna give it a try! (Yay!), but you don’t wanna deal with Kubernetes, (nay)o worries; we have a tool for you. Introducing the Percona DBaaS Infrastructure Creator, or Percona My Database as a Service (MyDBaaS).

Mysql Database Service (MDS) is a fully managed, native Oracle Cloud Infrastructure (OCI) service. Being part of OCI means that we can tap into the alarm and notification services to help manage our MDS instances. In this post, we will show how to create an alarm when an MDS instance becomes unavailable.

MySQL Database Service (MDS) is a fully-managed Oracle Cloud Infrastructure (OCI) service that allows you to harness the ease and power of MySQL in the cloud.

In my lab, we have two test nodes:

PRIMARY:  mysql57 (192.168.56.111)    with   Percona Server 5.7 and  xtrabackup 2.4 installed
REPLICA:  mysql8    (192.168.56.113)   with  Percona Server 8  and   xtrabackup 8.0 installed

0. Pre-flight check with MySQL upgrade checker utility

Let’s run the MySQL upgrade checker utility to verify whether MySQL 5.7 server instances are ready for an upgrade.
