Create Database Cluster
With Arvancloud Managed Database, you can easily create a database cluster with the resources you want and a few clicks. To create a new cluster, enter the " Managed Database " menu and the " All Databases " section from the user panel.
Click the "New Database Cluster" button to get started with creating a new cluster.
1st Step: Select Datacenter
First, choose a datacenter to host your database cluster. We suggest choosing a datacenter that is closer to the application connected to the database for more efficiency and speed of your service.
Currently, only Bamdad datacenter is available to you, and other datacenters will be activated in the future.
2nd Step: Select Database Engine
In this section, you can choose the engine you want for the database.
Currently, you can build database clusters with MySQL engine, and in the future, building clusters with MongoDB, PostgreSQL, and Redis will be available.
3rd Step: Select Database Plan
Here, you can choose the RAM, CPU, and disk of your cluster nodes.
In the future, the resizing feature will be added to the Arvancloud Managed Database, and after creating the cluster, you can change the amount of resources.
Change Disk Size
In this step by clicking on the "Change Disk Size" option, you can choose the disk size of your choice by entering the desired value.
Due to data loss and performance issues, it is not possible to decrease the disk size. However, in the next versions, you will be able to increase the disk size after setting up a database cluster.
4th Step: High Availability
Standby nodes store a copy of the main node's data and are always in sync with it to replace it if there was an issue with the primary node. This replacement happens in the fastest possible time and with the least downtime. When creating a new cluster, you can add one or two standby nodes.
All Arvancloud database clusters have an automatic failover mechanism and when an error occurs in the primary node, they replace it with another node. However, to achieve High Availability and reduce service recovery time, it is highly recommended to add a standby node to your cluster.
If you do not add a standby node to the cluster and the primary node fails, the cluster will be unavailable until the replaced node is activated. This time can vary based on the amount of data in your cluster, and the larger the data, the longer the cluster recovery time.
Currently, you can add only one standby node to the cluster.
Final Settings
Finally, choose a name for your cluster. Then check the cluster specifications and if you approve, click on "Create Database Cluster".
After that, you can monitor the process on the "All Databases" page.
Also, by clicking on the cluster, you can get the its connection details.
