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 …
