Whether you use unbreakable private datacenters or public cloud platforms, Disaster Recovery (DR) is indeed a key issue. This is not about copying your data to a backup site and being able to restore it, this is about business continuity and how fast you can recover services when disaster strikes.
Combining Galera and asynchronous replication in the same MariaDB setup, aka Hybrid Replication, can be useful - e.g. as a live backup node in a remote datacenter or reporting/analytics server. We already blogged about this setup for Codership/Galera or Percona XtraDB Cluster users, but master failover did not work for MariaDB because of its different GTID approach. In this post, we will show you how to deploy an asynchronous replication slave to MariaDB Galera Cluster 10.x (with master failover!), using GTID with ClusterControl v1.2.10.
SST can be painful in some occasions, as it can block the donor node (with SST methods like mysqldump or rsync) and burden it when backing up the data and feeding it to the joiner. For a dataset of a few hundred gigabytes or more, the syncing process can take hours to complete - even if you have a fast network. It might be advisable to avoid e.g. when running in WAN environments with slower connects and limited bandwidth, or if you just want a very fast way of introducing a new node in your cluster.
Vagrant is a system that allows you to easily create and move development environments from one machine to another. Simply define what type of VM you want in a file called Vagrantfile and then fire them up with a single command. It integrates well with virtual machine providers like VirtualBox, VMware and AWS. In this blog, we’ll show you how to expedite the deployment of your development environment using some Vagrant boxes we’ve put together.
Kubernetes is a system for managing containerized applications in a clustered environment. It provides basic mechanisms for deployment, maintenance and scaling of applications on public, private or hybrid setups. It also comes with self-healing features where containers can be auto provisioned, restarted or even replicated.
Today, we’re excited to announce our first step towards dockerizing our products. Please welcome the official ClusterControl Docker image, available on Docker Hub. The Docker image comes with ClusterControl installed and configured with all of its components, so you can immediately use it to manage and monitor your existing databases.
Data security is a hot topic for many companies these days. But for those who need to adhere to security standards like PCI DSS or HIPAA, security is not an option. We showed you sometime back how to encrypt Galera replication traffic, but for a more complete solution, you’ll want to encrypt all database connections from client applications and any management/monitoring infrastructure.
Atlassian apps are widely used by development teams to facilitate software development and collaboration. For larger teams who require enterprise-grade tools, you might want to host the applications in your own data center and cluster them for high availability and performance.
As your needs change, and you start managing more database instances or larger centralized backups with ClusterControl, you might find that your controller host is over-utilized. Or you might need to migrate your infrastructure to the cloud. If this is the case, you can migrate to another instance.
We are excited to announce support for PostgreSQL, probably the world’s most advanced open source RDBMS. ClusterControl can now be used to monitor database metrics, queries and schedule backups. With this new addition, ClusterControl now supports MySQL with its main variations MariaDB, Percona XtraDB (single or clustered), MongoDB and PostgreSQL. Companies can manage all these databases through one unified interface.
