Galera as central building block for OpenStack high availability

By Erkan Yanar 02-11-2014

 

OpenStack is likely the most popular open-source cloud computing platform (for IaaS or PaaS). Running OpenStack for yourself or for customers you likely want to run it without losing data and be able to scale while business grows. In this blog we are going to give a short overview to the OpenStack architecture, focusing on the Database(MySQL/MariaDB) part. Then we are going to discuss why Galera is an essential building block to achieve HA of the database and provide scaling even for very big installations.

 

The quite basic setup consists of:

A dashboard (program codename Horizon) providing a WebUI to manage OpenStack. Authentication is done via the identity service (Keystone). The Images service (Glance) provides images i.e. Ubuntu LTS, Centos7, etc. to start from. The Nova service starts them on a compute node. If you like to have persistent volumes you can also …

Running a Galera Cluster for MySQL on Microsoft Azure

By Holger Kenn

 

A few weeks ago, I was looking into running a MySQL Galera Cluster for a customer with a large Linux IAAS deployment on Azure.

Why that? There’s ClearDB, a Microsoft Partner that offers MySQL on Azure as SaaS (Software as a service), so you can go to https://www.cleardb.com/store/azure and pick your size. Or, if you want to run it on your own, you can pick a Ubuntu Linux Gallery image and type “apt-get install mysql-server” and that’s it, right? Well, not so fast…

ClearDB is a great offering for most customers that need a MySQL backend, but in this case, even the largest ClearDB offer was not sufficient.

So the customer followed the second path down, he created an IAAS VM (actually several VMs which each run an independent database server for different purposes) and configured his services to use these …

Top Two Signs your MySQL Database is Maxing Out

One of the main responsibilities of any database administrator is to keep a close eye on how database performance is impacting size and storage. Decisions will have to be made on whether or not to make changes within the database structure or application itself, or to make the changes on the storage and resource side [...] Read More

How to Tune a MySQL Application Like a Piano

In MySQL tuning pertains to either the application or the database system. In this post, we cover some common tuning techniques and best practices to increase your [...] Read More

Calling all next gen app providers: Who’s got your back?

Next gen app providers (and perhaps more specifically, database architects) are clamoring for database technologies that just work. At least, that’s the message we got from one of our newest customers: Mozilla. Earlier this month, we caught up with Sheeri Cabral, database architect at Mozilla and and overall MySQL rock star, to get the down-and-dirty on why [...] Read More

Linus on Instantiation and Armadaification

I feel a sense of pride when I think that I was involved in the development and maintenance of what was probably the first piece of software accepted into Debian which then had and still has direct up-stream support from Microsoft. The world is a better place for having Microsoft in it. The first operating system I ever ran on an 08086-based CPU was MS-DOS 2.x. I remember how thrilled I was when we got to see how my friend’s 80286 system ran BBS software that would cause a modem to dial a local system and display the application as if it were running on a local machine. Totally sweet.

When we were living at 6162 NE Middle in the nine-eight 292, we got an 80386 which ran Doom. Yeah, the original one, not the fancy new one with the double barrel shotgun, but it would probably run that one, too. It was also …
