Announcing Galera Cluster 5.7.18, 5.6.36 and 5.5.55 with Galera 3.21. Improvements to IPv6 Support, Bug Fixes and Changes to Repositories Structure

Codership is pleased to announce a new release of Galera Cluster for MySQL
consisting of MySQL-wsrep 5.7.18, 5.6.36, 5.5.55 and Galera 3.21, wsrep API
version 25.

Changes to Repositories Structure

With the new release the repository structure is changed to allow for
existence of all of the wsrep-patched mysql versions currently supported:
5.5 through 5.7.

Thus the repository layout requires from the user to adjust his or her
repository configuration to accomodate those changes. In order to have the
MySQL-wsrep and Galera library installed, one would need to add the following
repositories:

1. Galera-3 repository for galera library:
e.g. http://releases.galeracluster.com/galera-3/DIST/

Here DIST is Linux distribution (ubuntu, centos, …).

The latest version of Galera for FreeBSD is available in FreeBSD Ports

3 Ways to Boost Cloud Scalability

Deploying in the Amazon cloud is touted as a great way to achieve high scalability while paying only for the computing power you use. How do you get the best scalability from the technology?

1. Use Auto-scaling

Auto-scaling is a unique feature of cloud computing and Amazon's EC2 offering. Setup a load balancer and a couple of webservers for your application as you normally would. Design your webserver based on a template AMI that you'll reuse over and over. Then setup auto-scaling and set thresholds based on the traffic you forecast. When a threshold is passed, AWS will spinup a new instance of your webserver, and roll it into the load balancer pool automatically. Once traffic falls below the scale back threshold, Amazon will take a server out of the pool for you.

Be sure to monitor this …
