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](http://www.tecmint.com/wp-content/uploads/2017/01/MySQL-Clusters-Galera-Replications.png) +][4] + +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. + +-------------------------------------------------------------------------------- + +作者简介： + +I am Ravi Saive, creator of TecMint.
