Configuring PostgreSQL for Business Continuity

Business continuity for databases means databases must be continuously operational even during the disasters. It is imperative to ensure that production databases are available for the applications all the time even during the disasters, otherwise, could end-up being an expensive deal.

How to Replicate PostgreSQL Data to Remote Sites

In a busy database environment with larger size databases, the need for real-time data replication is a common occurrence. Applications often need the production data to be replicated in real-time to remote sites for analytics and other critical business operations needs. This blog provides an overview of several options you can use to replicate your PostgreSQL data to a remote site.

HA for MySQL and MariaDB - Comparing Master-Master Replication to Galera Cluster

Replication and Galera Cluster are both widely used to implement high availability for MySQL/MariaDB, but when should you pick one over the other? What are the limitations of each solution, and what are the trade offs?
In this blog post, we will look at the differences in terms of data consistency, conflict resolution, failover, node provisioning and robustness.

High Availability on a Shoestring Budget - Deploying a Minimal Two Node MySQL Galera Cluster

Learn how to set up a Galera cluster with just 2 nodes and use Garbd to retain high availability.

PostgreSQL Replication for Disaster Recovery

This blog explains how to utilize streaming replication and point in time recovery to achieve high availability using failover.

Webinar Replay: How to Manage Replication Failover Processes for MySQL, MariaDB & PostgreSQL

Watch the replay of this webinar for a detailed overview of what failover processes may look like in MySQL, MariaDB and PostgreSQL replication setups. We’ll cover the dangers related to the failover process and look at how ClusterControl manages it as well as how it can be configured for both assisted and automated failover.

MySQL on Docker: Multiple Delayed Replication Slaves for Disaster Recovery with Low RTO

A delayed replication slave is useful in recovering from accidental data deletion. But how long should the delay be? Too short delay might not be enough for you to get to a terminal and stop an offending query. Too long delay means a long recovery time when catching up.

This blog post shows how to deploy multiple MySQL delayed slaves on one single physical host with Docker, and shows some of the recovery scenarios.

Simple Scheduling of Maintenance Windows across your Database Clusters

Maintenance is something that an operation team can not avoid. ClusterControl can be configured to simplify your maintenance routines. In this post, we’ll show you some advanced use cases of cluster-wide maintenance with iterations using ClusterControl CLI.

How to Deploy PostgreSQL for High Availability

In this blog, we will review some important concepts of High Availability, possible database HA architectures and useful components when implementing PostgreSQL HA. Then we will see how to use ClusterControl to deploy an entire high availability stack for PostgreSQL.
