How to Deploy Galera Cluster for MySQL using Docker Containers
+0 Vote Up -0Vote Down

February 18, 2014 By Severalnines

Virtual Machines are great, and very useful when trying out new software. However, they might be an unnecessarily heavyweight solution when testing clusters, especially if these consist of multiple nodes running exactly the same software. Each VM runs a full-blown OS image. On the other hand, Linux Containers (LXC) are an efficient alternative to OS-level virtualization and can run multiple isolated systems on a single host. Docker is a wrapper around LXC, it automates the deployment of applications inside containers. 

A notable advantage if you run with Docker + LXC is you can run …

Galera is slowly but surely establishing itself as a credible replacement for traditional MySQL master-slave architectures. 

The benefits are clear - a true multi-master InnoDB setup with built-in fail-over, potentially across data centers. 

But how do you migrate? Does the schema or application change? What are the limitations? Can migration be done online, without service interruption? What are the potential risks, and how to address those?

February 3, 2014 By Severalnines

Liferay is an open-source content management system written in Java. It is used by a number of high traffic sites, as this survey suggests. 

Clustering Liferay and other components such as the database and the file system is a good way to handle the performance requirements of a high traffic site. The latest Liferay version has introduced features that simplify clustering, such as built-in support for Ehcache clustering, Lucene replication, read/write splitting capabilities for …

Benchmarking Galera Cluster
+4 Vote Up -0Vote Down

What is it about?

I used to do some benchmarkstuff and blogged about it on my blog written in German. Im going to do testings and benchmarkings again:)

We are going to have a look into ‘benchmarking’ a 3-node Galera Cluster. The application (sysbench) is on a separate node accessing one node of the cluster. This would be the case in a i.e. VIP setup.

Setup

3 Galera Nodes

  • Virtual machines (OpenStack) provided by teuto.net
  • VCPU: 4
  • RAM: 4GB
  • OS: Centos 6.4-x86_64
