Percona Live Dublin – Event Recap & Our Sessions

Forrest Lymburner


Severalnines was pleased to yet again sponsor Percona Live Europe, the Open Source Database Conference which was held this year in Dublin, Ireland.

At the Conference

Severalnines team members flew in from around the world to partner up with our two local Dubliners to demo ClusterControl in the exhibit hall and present three sessions (see below).

On our Twitter feed we live tweeted both of the keynote sessions to help keep those who weren’t able to attend up-to-speed on the latest happenings in the database world.

We were also able to sit down with René Cannaò, creator of ProxySQL to talk about what’s new with the exciting load balancing technology.

Our Sessions

Members of the Severalnines team presented three technical sessions, all of which were widely attended… some with standing room only!

MySQL Load Balancers – MaxScale, ProxySQL, HAProxy, MySQL Router & nginx – A Close Up Look

Session Details: Load balancing MySQL connections and queries using HAProxy has been popular in the past years. Recently however, we have seen the arrival of MaxScale, MySQL Router, ProxySQL and now also Nginx as a reverse proxy.

For which use cases do you use them and how well do they integrate in your environment? This session aims to give a solid grounding in load balancer technologies for MySQL and MariaDB.

We review the main open-source options available: from application connectors (php-mysqlnd, jdbc), TCP reverse proxies (HAproxy, Keepalived, Nginx) and SQL-aware load balancers (MaxScale, ProxySQL, MySQL Router).

We also look into the best practices for backend health checks to ensure load balanced connections are routed to the correct nodes in several MySQL clustering topologies. You’ll gain a good understanding of how the different options compare, and enough knowledge to decide which ones to explore further.

MySQL on Docker – Containerizing the Dolphin

Session Details: Docker is becoming more mainstream and adopted by users as a method to package and deploy self-sufficient applications in primarily stateless Linux containers. It’s a great toolset on top of OS-level virtualization (LXC, a.k.a containers) and plays well in the world of micro services.

However, Docker containers are transient by default. If a container is destroyed, all data created is also lost. For a stateful service like a database, this is a major headache to say the least.

There are a number ways to provide persistent storage in Docker containers. In this presentation, we will talk about how to setup a persistence data service with Docker that can be torn down and brought up across hosts and containers.

We touch upon orchestration tools, shared volumes, data-only-containers, security and configuration management, multi-host networking, service discovery and implications on monitoring when we move from host-centric to role-centric services with shorter life cycles.

Automating and Managing MongoDB: An Analysis of Ops Manager vs. ClusterControl

Session Details: In any busy operations environment, there are countless tasks to perform – some monthly, or weekly, some daily or more frequently, and some on an ad-hoc basis. And automation is key to performing fast, efficient and consistently repeatable software deployments and recovery.

There are many generic tools available, both commercial and open source, to aid with the automation of operational tasks. Some of these tools are even deployed in the database world. However, there are a small number of specialist domain-specific automation tools available also, and we are going to compare two of these products: MongoDB?s own Ops Manager, and ClusterControl from Severalnines.

We cover Installation and maintenance, Complexity of architecture, Options for redundancy, Comparative functionality, Monitoring, Dashboard, Alerting, Backing up and restoring, Automated deployment of advanced configurations, and Upgrading existing deployments

Thanks to the Percona Team for organising another great conference and to everyone who participated from near and afar! We hope to see you again soon!
