ChatOps - Managing MySQL, MongoDB & PostgreSQL from Slack

CCBot helps you monitor and manage your database Infrastructure from Slack. ChatOps is about bringing your DevOps work to your chats and conversations within a team, e.g. Slack.

Updated: Become a ClusterControl DBA: Safeguarding your Data

So now that you have your databases up and running and highly available, how do you ensure that you have backups of your data? You can use backups for multiple things: disaster recovery, to provide production data to test against development or even to provision a slave node. This last case is already covered by ClusterControl. When you add a new (replica) node to your replication setup, ClusterControl will make a backup/snapshot of the master node and use it to build the replica.

Updated: Become a ClusterControl DBA - Deploying your Databases and Clusters

Many of our users speak highly of our product ClusterControl, especially how easy it is to install the software package. Installing new software is one thing, but using it properly is another. We all are impatient to test new software and would rather like to toy around in a new exciting application than to read documentation up front. That is a bit unfortunate as you may miss the most important features or find out the way of doing things yourself instead of reading how to do things the easy way.

Become a ClusterControl DBA: Adding Existing Databases and clusters (updated)

In our previous blog post we covered the deployment of four types of clustering/replication: MySQL Galera, MySQL master-slave replication, PostgreSQL replication set and MongoDB replication set. This should enable you to create new clusters with great ease, but what if you already have 20 replication setups deployed and wish to manage them with ClusterControl?
