Getting Started with MySQL Clusters as a Service
|
||
============================================================
|
||
|
||
[MySQL Cluster.me][1] starts offering **MySQL Clusters** and **MariaDB Clusters** as a service based on **Galera Replication** technology.
|
||
|
||
In this article we will go through the main features of a **MySQL** and **MariaDB** clusters as a service.

MySQL Clusters as a Service
|
||
|
||
### What is a MySQL Cluster?
|
||
|
||
If you have ever wondered how you can increase the reliability and scalability of your MySQL database you might have found that one of the ways to do that is through a **MySQL Cluster** based on **Galera Cluster** technology.
|
||
|
||
This technology allows you to have a complete copy of the MySQL database synchronized across many servers in one or several datacenters. This lets you achieve high database availability – which means that if `1` or more of your database servers crash then you will still have a fully operational database on another server.
|
||
|
||
It is important to note that the minimum number of servers in a **MySQL Cluster** is `3` because when one server recovers from a crash it needs to copy data from one of the remaining two servers making one of them a “**donor**“. So in case of crash recovery you must have at least two online servers from which the crashed server can recover the data.
|
||
|
||
Also, a [MariaDB cluster][3] is essentially the same thing as MySQL cluster just based on a newer and more optimized version on MySQL.

MySQL Clusters Galera Replications

### What is a MySQL Cluster and MariaDB Cluster as a Service?
|
||
|
||
**MySQL Clusters** as a service offer you a great way to achieve both requirements at the same time.
|
||
|
||
First, you get **High Database Availability** with a high probability of **100% Uptime** in case of any datacenter issues.
|
||
|
||
Secondly, outsourcing the tedious tasks associated with managing a mysql cluster let you focus on your business instead of spending time on cluster management.
|
||
|
||
In fact, managing a cluster on your own may require you to perform the following tasks:
|
||
|
||
1. **Provision and setup the cluster** – may take you a few hours of an experienced database administrator to fully setup an operational cluster.
|
||
2. **Monitor the cluster** – one of your techs must keep an eye on the cluster 24×7 because many issues can happen – cluster desynchronization, server crash, disk getting full etc.
|
||
3. **Optimize and resize the cluster** – this can be a huge pain if you have a large database and you need to resize the cluster. This task needs to be handled with extra care.
|
||
4. **Backups management** – you need to backup your cluster data to avoid it being lost if your cluster fails.
|
||
5. **Issue resolution** – you need an experienced engineer who will be able to dedicate a lot of effort optimizing and solving issues with your cluster.
|
||
|
||
Instead, you can save a lot of time and money by going with a **MySQL Cluster** as a Service offered by **MySQLcluster.me** team.
|
||
|
||
###### So what’s included into MySQL Cluster as a Service offered by MySQLcluster.me?
|
||
|
||
Apart from high database availability with an almost guaranteed uptime of **100%**, you get the ability to:
|
||
|
||
1. **Resize the MySQL Cluster at any time** – you can increase or decrease cluster resources to adjust for the spikes in your traffic (RAM, CPU, Disk).
|
||
2. **Optimized Disks and Database Performance** – disks can achieve a rate of **100,000 IOPS** which is crucial for database operation.
|
||
3. **Datacenter Choice** – you can decide in which datacenter you would like to host the cluster. Currently supported – Digital Ocean, Amazon AWS, RackSpace, Google Compute Engine.
|
||
4. **24×7 Cluster Support** – if anything happens to your cluster our team will always assist you and even provide you advice on your cluster architecture.
|
||
5. **Cluster Backups** – our team sets up backups for you so that your cluster is automatically backed up on a daily basis to a secure location.
|
||
6. **Cluster Monitoring** – our team sets up automatic monitoring so in case of any issue our team starts working on your cluster even if you are away from your desk.
|
||
|
||
There are a lot of advantages of having your own **MySQL Cluster** but this must be done with care and experience.
|
||
|
||
Speak to [MySQL Cluster][5] team to find the best suitable package for you.
