Picking the right clustering for MySQL: Cloud-only services or flexible Tungsten clusters?
+0 Vote Up -0Vote Down
As businesses head into the cloud, it is tempting to reach for the first product that offers to make database operation as simple as punching a few buttons on a menu.  However, there’s a big difference between firing up cloud database services such as Amazon RDS for testing or development and finding a solution that can handle hundreds of millions of transactions daily. This webinar explores how
Announcing ClusterControl Support for MariaDB 10

July 22, 2014 By Severalnines

We just wanted to make it official: Severalnines ClusterControl now supports MariaDB 10!

 

As most of you know will know by now, MariaDB 10 is the newest and most advanced version of the popular MariaDB relational database system. Whilst remaining application-compatible with the MySQL database, it adds many new capabilities to address the most challenging web and enterprise application use cases. Cluster deployments would be based on MariaDB Galera Cluster 10, which is a complete merge of MariaDB 10.0.12 and Galera Cluster.

Harnessing the power of master/slave clusters to operate data-driven businesses on MySQL

Users seeking high availability, DR and zero downtime maintenance operation for business-critical MySQL applications face confusing choices. Is multi-master or master/slave clustering better?  What about synchronous versus asynchronous replication? Using a plain vanilla, stock MySQL or a modified version of it? Which of these choices are right for data-driven businesses that depend on fast,

June 17, 2014 By Severalnines

 

We continuously see great interest in MySQL load balancing and HAProxy, so we thought it was about time we organised a live webinar on the topic!

 

As most of your will know, database clusters and load balancing go hand in hand. 

 

Once your data is distributed and replicated across multiple database nodes, a load balancing mechanism helps distribute database requests, and gives applications a single database endpoint to connect to.

The first version of MySQL Cluster 7.4 has now been released on MySQL Labs. Note that labs loads are not suitable for production use (in fact they’re even less mature than Development Milestone Releases); their purpose is to give users a chance to see what’s in the works, try it for themselves and then provide feedback. Having read that, if you’d like to try it out then Download MySQL Cluster 7.4 from MySQL Labs.

MySQL Cluster on Raspberry Pi - Sub-second failover
Employee +1 Vote Up -0Vote Down
MySQL Cluster claims to achieve sub-second failover without any data loss for commited transactions. And I always wanted to show this in a demo. Now we created that demo finally. See Mark's blog and Keith's blog for setting up MySQL Cluster on RaspberryPi.
The nice thing about the RPis is that you can easily pull the plug to test failover. Ok, that is only one possible failure scenario but for sure the most obvious and more impressive than "kill -9".


That demo application is constantly using the database for storing new lines, removing old lines and reading all line data for the graphical view. There is no caching. It uses JDBC directly.

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?

Deploying an Active-Active FreeRadius Cluster with MySQL NDB or Galera
+0 Vote Up -0Vote Down
January 6, 2014 By Severalnines

MySQL Cluster is a popular backend for FreeRADIUS, as it provides a scalable backend to store user and accounting data. However, there are situations when the backend database becomes a centralized datastore for additional applications and services, and needs to take a more general-purpose role. NDB usually works very well for FreeRADIUS data, but for wider use cases and reporting type applications, InnoDB can be a better storage engine. For users who need to keep their data in InnoDB and still benefit from a highly available clustered datastore, Galera Cluster can be an appropriate alternative.

In this post, we will show you how to deploy FreeRadius both with MySQL Cluster and Galera Cluster to store

New Webinar: Repair and Recovery for your MySQL, MariaDB and MongoDB/TokuMX Clusters

December 19, 2013 By Severalnines


Database clusters are pretty sophisticated distributed systems with complex dependencies between nodes. The failure of a node will generally impact the overall cluster, as the remaining nodes need to reconfigure themselves to continue to operate without the failed node. Since re-introducing a node will also affect the existing cluster, the timing could therefore be dependent on the state of the other nodes in the cluster. Repair and restarts often needs to be performed
