Often databases contain data that needs to be proven as valid and authentic. We want to ensure that a known person or other sender (e.g. a trusted app) of the information can’t deny content, nor that the content can change without that person (senders) consent.…

While the idea of containers have been around since the early days of Unix, Docker made waves in 2013 when it hit the market with its innovative solution. What began as an open source project, Docker allows you to add your stacks and applications to containers where they share a common operating system kernel. This lets you have a lightweight virtualized system with almost zero overhead. Docker also lets you bring up or down containers in seconds, making for rapid deployment of your stack.

Severalnines, like many other companies, got excited early on about Docker and began experimenting and developing ways to deploy advanced open source database configurations using Docker containers. We also released, early on, a docker image of ClusterControl that lets you utilize the management and monitoring …

Register Now  MySQL is famous for being something you can install and get going in less than five minutes in terms of development. But normally you want to run MySQL in production, and at scale. This requires some planning and knowledge. So why not learn the best practices around installation, configuration, deployment and backup?

In this blog, we’ll look at different MySQL high availability options.

The dynamic MySQL ecosystem is rapidly evolving many technologies built around MySQL. This is especially true for the technologies involved with the high availability (HA) aspects of MySQL. When I joined Percona back in 2009, some of these HA technologies were very popular – but have since been almost forgotten. During the same interval, new technologies have emerged. In order to give some perspective to the reader, and hopefully help to make better choices, I’ll review the MySQL HA landscape as it is in 2017. This review will be in three parts. The first part (this post) will cover the technologies that have been around for a long time: the elders. The second part will focus on the technologies that are very popular today: the adults. Finally, the last part will try to extrapolate which technologies could become popular in the upcoming years: the …

The hashicorp/raft library is a Go library to provide consensus via Raft protocol implementation. It is the underlying library behind Hashicorp's Consul.

I've had the opportunity to work with this library a couple projects, namely freno and orchestrator. Here are a few observations on working with this library:

• TL;DR on Raft: a group communication protocol; multiple nodes communicate, elect a leader. A leader leads a consensus (any subgroup of more than half the nodes of the original group, or hopefully all of them). Nodes may leave and rejoin, and will remain consistent with consensus.
• The hashicorp/raft library is an implementation of …
