The Best Way to Host MySQL on Azure Cloud

Are you looking to get started with the world’s most popular open-source database, and wondering how you should setup your MySQL hosting? So many default to Amazon RDS, when MySQL performs exceptionally well on Azure Cloud. While Microsoft Azure does offer a managed solution, Azure Database, the solution has some major limitations you should know about before migrating your MySQL deployments. In this post, we outline the best way to host MySQL on Azure, including managed solutions, instance types, high availability replication, backup, and disk types to use to optimize your cloud database performance.

MySQL DBaaS vs. Self-Managed MySQL

The first thing to consider when weighing between self-management and a MySQL Database-as-a-Service …

Galera Cluster at Percona Live Austin, DataOps.Barcelona and where next

It is July now, and summer is upon us. The team at Codership are busy making Galera Cluster 4 for MySQL, and we are just hot of the heels of celebrating the launch of Galera Cluster 4 with MariaDB Server 10.4

At the end of May, Galera Cluster had a booth and several talks at Percona Live Austin. This was the first time the event happened there, and we thoroughly enjoyed it.

Galera Cluster 4 with MariaDB 10.4

Congratulations to Team MariaDB at MariaDB Corporation and MariaDB Foundation for releasing MariaDB 10.4.6 as Generally Available (GA) last week on 18 June 2019. This release is very exciting for Galera Cluster users as it comes with Galera 4 (it is now the first server to come with it!), with Galera wsrep library version 26.4.2.

What can Galera Cluster users expect from MariaDB 10.4? Some high level features include:

  • Streaming replication — a huge boost to large transaction support, since the node breaks transactions into fragments, replicates and certifies it across all secondary nodes while the transaction is still in progress. Read more about it in our dedicated documentation on streaming replication as well …

The MySQL High Availability Landscape and where Galera Cluster fits in (USA and EMEA Webinar)

The MySQL Server High Availability landscape provides with a slew of tools to help you ensure that your databases keep humming. Such tools are Galera Cluster, however, it is worth looking at semi-synchronous replication with failover tools, and also the usual leader-follower asynchronous replication. Today more workloads are moving to the cloud, and what failover options do you get with Amazon RDS for MySQL or even Aurora? What about the newfangled group replication and InnoDB Cluster? And let us not forget that Galera Cluster has spawned branches too!

Join Codership, the developers and experts of Galera Cluster,  as we discuss where Galera Cluster fits in and how to get best out of it.

MariaDB OpenWorks was an ocean of Galera Cluster activity

MariaDB OpenWorks happened February 25 – 27, 2019 in New York City. It was filled with plenty of activity.

The keynote by Michael Howard, C.E.O. of MariaDB, is an interesting watch, one with many quoted articles especially around “strip-mining open-source technologies and companies,” and “abusing the license and privilege, and not giving back to the community.” Many articles were written about this topic, and it’s clear that open-source has arrived considering all of the success around the IBM acquisition of Red Hat, the Elastic I.P.O., the Microsoft acquisition of GitHub, the SalesForce acquisition fo MuleSoft and the MongoDB I.P.O.

Seppo Jaakola, the C.E.O. of Codership, talked about …
