So, maybe you’ve been working with MySQL for a while and are now being asked to also properly maintain one or more MongoDB instances. It is not uncommon that MySQL DBAs, developers, network/system administrators or DevOps folks with general backgrounds, find themselves in this situation at some point in time. In fact, with more organisations operating polyglot environments, it’s starting to become commonplace. With that said, we’d like to introduce a new webinar series: ‘How to Become a MongoDB DBA’ to answer the question: ‘what does a MongoDB DBA do’? In the space of three webinars, we will walk you through the most important tasks a MongoDB DBA routinely goes through and provide you with options on how to best complete these tasks. In this initial webinar of the series, we will go beyond the deployment phase and show you how you can automate tasks, how to monitor a cluster and how to manage MongoDB; whilst also automating and managing your MySQL and/or PostgreSQL installations. Agenda Introduction to becoming a MongoDB DBA Installing & configuring MongoDB What to monitor and how How to perform backups Live Demo Speaker Art van Scheppingen is a Senior Support Engineer at Severalnines. He’s a pragmatic MySQL and Database expert with over 15 years experience in web development. He previously worked at Spil Games as Head of Database Engineering, where he kept a broad vision upon the whole database environment: from MySQL to Couchbase, Vertica to Hadoop and from Sphinx Search to SOLR. He regularly presents his work and projects at various conferences (Percona Live, FOSDEM) and related meetups.
