Setting Up a Galera Cluster on Amazon AWS EC2

Through Amazon Web Services (AWS), you can create virtual servers (i.e., instances). You can install database and Galera software on them. In this article, we’ll create three nodes, the minimum recommended for a healthy cluster, and configure them to use Galera Cluster.

Incidentally, there is a more detailed version of this article in the Tutorial section of our Library.

Assumptions & Preparation

We’re assuming you have an AWS account and know the basics of the EC2 (Elastic Compute Cloud) platform.

To access the nodes, you’ll need an encryption key. Create a new one specifically for Galera, using a tool such as ssh-keygen. Add that key to AWS, under Key Pairs.

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.

Running Galera Cluster effectively on Amazon Web Services (AWS) and comparing it to RDS and Aurora (EMEA and USA webinar)

Do you want to run Galera Cluster in the cloud? Why not learn to setup a 3-node Galera Cluster using Amazon Web Services (AWS) Elastic Compute Cloud (EC2), and run it yourself (3-node because this is the minimum preferred size; you can have a 5, 7, or 9 node cluster too — not in the demo though!). In this webinar, we will cover the steps to do this, with a demonstration of how easy it is for you to do. We will also cover how you may want to load balance traffic to your Galera Cluster using a proxy like ProxySQL.

In addition, we will cover why you may want to run a 3-node (or more) Galera Cluster (multi-master synchronous clusters) instead of (or in addition to) using Amazon Relational Database Service (RDS) MySQL, which has the ability to have asynchronous replication (Read Replicas), and High Availability provided by DRBD (Multi-AZ). We will also cover where Galera Cluster differs from Amazon Aurora RDS for MySQL.

Things to remember while using Galera Cluster Streaming Replication

What are things you must consider before using Galera Cluster Streaming Replication ? 

In Streaming Replication, the node breaks the transaction into fragments, then certifies and replicates them on the slaves while the transaction is still in progress. Once certified, the fragment can no longer be aborted by conflicting transactions. Additionally, Streaming Replication allows the node to process transaction write-sets greater than 2Gb. So, How do you decide whether go with Galera Cluster Streaming Replication or not ? We caution our customers before choosing Galera Cluster Streaming Replication considering several limitations and costs attached to it (explained below the limitations of Galera Cluster Streaming Replication in this post). Even you have decided to proceed with Galera Cluster Streaming Replication, We recommend you to enable it only for a session-level and then only on specific transactions.
