Define the Backup Policy when deploying MySQL Database Service in OCI

Let’s continue the discovery of the MySQL Database Resource when deploying on Oracle Cloud Infrastructure using Terraform.

Last week, we saw how to create custom configurations and define user variables. Today we will see how we can define a backup policy and a maintenance window.

Backup Policy

In the oci_mysql_mysql_db_system resource, we will add a new section called backup_policy like this:

backup_policy {
       is_enabled        = "true"
       retention_in_days = "3"
       window_start_time = "01:00-00:00"
       freeform_tags = {"backup_defined_by"="Terraform"}
       pitr_policy {
            is_enabled = "true"

This part of code (you can see in a working Terraform architecture sample), enables backup, sets the retention days to 3. It also defines the starting …

MySQL in Microservices Environments

The microservice architecture is not a new pattern but has become very popular lately for mainly two reasons: cloud computing and containers. That combo helped increase adoption by tackling the two main concerns on every infrastructure: Cost reduction and infrastructure management.

However, all that beauty hides a dark truth:

The hardest part of microservices is the data layer

And that is especially true when it comes to classic relational databases like MySQL. Let’s figure out why that is.

MySQL and the microservice

Following the same two pillars of microservices (cloud computing and containers), what can one do with that in the MySQL space? What do cloud computing and containers bring to the table?

Cloud computing

The magic of the cloud is that it allows you to be cost savvy by letting you easily SCALE UP/SCALE DOWN the size of your instances. No more wasted money on …

Define your MySQL Configuration Variables on OCI with Terraform

With Terraform OCI provider 4.90.0 (released August 24th, 2022), we have added the possibility to specify the value of editable configuration variables directly from Terraform.

These variables must be defined in a resource of type oci_mysql_mysql_configuration like this:

resource "oci_mysql_mysql_configuration" "mds_mysql_configuration" {
        compartment_id = var.compartment_ocid
    shape_name   = var.mysql_shape

Stream MySQL data with mydumper

Mydumper supports streaming of backups right from version 0.11.3 and the latest version Mydumper 0.12.3 it enabled its support for compressed streaming backup. This was the most awaited feature added to Mydumper, making it a more powerful tool for data migration to RDS or Cloud.

If you are hearing mydumper for the first time, then let’s have a quick catch-up on what Mydumper is and what it does exactly.

Mydumper is a multithread logical backup and restores tool for MySQL and its forks. To know more you can refer to our previous blogs/presentations below.

Percona Server for MySQL – Automatic Cloud Deployment with Terraform

We are looking to provide simplified ways to deploy Percona software in cloud environments, especially for more advanced scenarios like replication and multi-node cluster (in the case of Percona XtraDB Cluster).

For this I propose trying out our new Terraform provider, with the capabilities:

  • Deploy in AWS or GCP Cloud. The provider will automatically create instances and deploy Percona Server for MySQL
  • Deploy either Percona Server for MySQL or Percona XtraDB Cluster
  • Choose instance size
  • Choose storage volume size, type, and IOPs
  • Multi-node async replication or multi-node Percona XtraDB Cluster
  • Customize MySQL configuration file
  • Capability to deploy MyRocks …

Percona XtraDB Cluster on Amazon EC2 and Two Interesting Changes in PXC 8.0

This article outlines the basic configurations for setting up and deploying Percona XtraDB Cluster 8.0 (PXC) on Amazon EC2, as well as what is new in the setup compared to Percona XtraDB Cluster 5.7.

What is Percona XtraDB Cluster an ideal fit for?

Percona XtraDB Cluster is a cost-effective, high-performance clustering solution for mission-critical data. It combines all the improvements, and functionality found in MySQL 8 with Percona Server for MySQL‘s Enterprise features and Percona’s upgraded Galera library.

A Percona XtraDB Cluster environment is an ideal fit for applications requiring 5-9s uptime with high read …

AWS RDS Backups: What’s the True Cost?

You have your database instance deployed with AWS and you are using AWS RDS for MySQL. All work smoothly in terms of satisfying queries for your application and delivering reliable uptime and performance. Now you need to take care of your backup strategy. Business is defined to have this retention policy:

  • 7 daily full backups
  • 4 weekly backups
  • 12 monthly backups

Plus the ability to do point-in-time recovery (PITR) for the last 24 hours since the last full backup was taken.

The cloud vendor solution

This is a piece of cake. The daily backups: just set the backup retention period to six days. Done. This also has the plus that PITR is already covered since RDS uploads the transaction logs to S3 every five minutes and stores them in the parquet format, making it smaller than the regular text file. All amazing, right?

Now, the weekly and …

Seven Ways To Reduce MySQL Costs in the Cloud

With the economy slowing down and inflation raging in many parts of the world, your organization will love you if you find ways to reduce the costs of running their MySQL databases. This is especially true if you run MySQL in the cloud, as it often allows you to see the immediate effect of those savings, which is what this article will focus on.

With so many companies announcing layoffs or hiring freezes, optimizing your costs may free enough budget to keep a few team members on or hire folks your team needs so much. 

1. Optimize your schema and queries

While optimizing schema and queries is only going to do so much to help you to save on MySQL costs in the cloud, it is a great thing to start with. Suboptimal …

MySQL Server on Microsoft Azure 3rd part (backup and recovery)

Azure Database for MySQLIntroduction

This blog is the third chapter related to deploying a MySQL infrastructure on the Azure cloud. In addition to performance, we should indeed also consider backup and restore capabilities. The objective of this blog is to present the main backup and restore possibilities offered by Azure through a simple example and show a second backup/restore possibility using MySQL Shell dump utilities.

Backup window and mechanism

Flexible Azure for MySQL generates by default a 7 days server backup retention period. This retention period can be extended up to 35 days or shorten to 1 day. In addition we can decide if you want to have a Geo Redundant backup storage. By default the backups are locally redundant.

It’s important to understand that Azure makes backup of the …

MySQL Server on Microsoft Azure 2nd part (Performance tests)

Azure Database for MySQLIntroduction

This second blog follows the first blog about deploying MySQL Server on Microsoft Azure. In the first blog, we saw how easy it is to deploy a MySQL server in minutes on the Azure cloud and we connected on it through the MySQL Shell client.

This second blog is more focused on the performance of MySQL in the Azure Cloud. Although I didn’t do any tuning of MySQL parameters, we will see the influence of MySQL Server localization on the latency as well as changes in parameters such as CPU, memory or IOPS on performances using the SysBench tool.

SysBench stress test

Of course there are many tools available to do stress tests. On my side, I decided to use SysBench simply because I know this wonderful free tool and because it is widely deployed. Rather than …
