The MySQL High Availability Landscape in 2017 (The Elders)

In this blog, we’ll look at different MySQL high availability options.

The dynamic MySQL ecosystem is rapidly evolving many technologies built around MySQL. This is especially true for the technologies involved with the high availability (HA) aspects of MySQL. When I joined Percona back in 2009, some of these HA technologies were very popular – but have since been almost forgotten. During the same interval, new technologies have emerged. In order to give some perspective to the reader, and hopefully help to make better choices, I’ll review the MySQL HA landscape as it is in 2017. This review will be in three parts. The first part (this post) will cover the technologies that have been around for a long time: the elders. The second part will focus on the technologies that are very popular today: the adults. Finally, the last part will try to extrapolate which technologies could become popular in the upcoming years: the …

Businesses are moving many of the systems and processes they once owned to offsite “service” models: Platform as a Service (PaaS), Software as a Service (SaaS), Infrastructure as a Service (IaaS), etc. These services are usually referred to as being “in the cloud” – meaning that the infrastructure and management of the service in …

Getting Started with MySQL Replication for High-Availability

Many organizations have MySQL or MariaDB databases at the core of their business—for processing and storing product sales, collecting information related to services offered, or just providing essential information to customers. As a result, keeping these databases running continuously can be critical for the success of an organization.

There are many components of a database system that a database administrator will need to consider for maintaining high availability. We considered server equipment (e.g., memory) in a previous introductory article. Now let’s look at using multiple servers for your MySQL and MariaDB databases—let’s look at replication.

Replication Overview

One common and effective way to structure a highly available database system is through some form of database replication. There are a few reasons …

Over the period of time we have made efforts to improve the management of this quintessential element of replication. To keep up with our raising standards and requirements coming from the global MySQL community we have introduced two new features to help you manage your binary logs more efficiently.…

Getting Started with MySQL High-Availability

Keeping databases running consistently and continuously is crucial to many organizations. When your site or application fails to load because of problems with your databases, you risk losing revenues—especially a business with a high traffic site which is the main source of revenues. If it happens often enough, you’ll lose not only transactions but customers.

There are many reasons why a database system may be unavailable, or at least not consistently available. It could be straightforward problems with your databases, or it could be hardware limitations. There are several potentially weak components of a database system. It’s important to know where are the potential weak points and to have a clear sense of what’s required to maintain a highly available database system.

If this concept is moderately new to you, it may be overwhelming. However, please understand that it’s achievable and learnable. You can start by focusing …
