“HA VPS" typically stands for High Availability Virtual Private Server. A High Availability VPS is a type of virtual server that is designed to minimize downtime and ensure continuous operation of applications and services. The VPS Application running on HA VPS continues to run despite underlying hardware pulldown for maintenance or unexpected hardware failure. Your host is always available and gives maximum uptime to your website.
The primary objective of an HA VPS is to enhance the reliability and availability of applications and services. This is particularly important for businesses and organizations that rely on continuous access to your website. It is the high time to consider migrating to a high-availability VPS hosting provider.
There are many VPS service providers still provide VPS in the traditional method where the provide slice of dedicated percentage of computing resource from a single physical server. If single server goes down, so your VPS and website will go down till the physcail server up and running. It is better than shared hosting because of each user isolated from each other but relies on underlying hardware uptime.
It is achieved by making redundant infrastructure with Server, Storage and Network
All Virtual Machines are in HA cluster, which means Data is distributed across these hosts, and if one host fails, the virtual machines (VMs) continue running on the remaining hosts. Which provides higher uptime to VM.
Our storage SAN employs a distributed RAID (Redundant Array of Independent Disks) mechanism, known as RAID-1 mirroring, across hosts. This ensures that if a disk fails, there is a replica of the data available on another disk within the cluster.
It's essential to have redundant networking to avoid a single point of failure. This involves multiple network interfaces on each host, with separate physical switches and paths for redundancy, and each network is connected to a different switch and Firewall so that if in case one path fails other paths will serve the network.
By accessing your VPS server it is difficult to get to know whether the VPS is in a single server model or in a cluster with HA mode. However, you can follow the below steps.
Yes, You can run any application as long as the underlying Operating system supports. You can run cPanel, Plesk, Tally ERP, mail server with HA.
If you have centralized storage then VM will stop running if any downtime with centralized storage. But in the case of CloudTreno HA VPS there is no centralized storage concept. Cloudtreno uses de-centralized distributed storage where VM data is replicated along multiple storage volumes. So, there is no single-point failure to Storage.
You need multiple frontend nodes if you want to perform application-level load balancing among users, especially in cases of high traffic volume, and when aiming for application-level high availability as well.
Yes, Backup is always recommended to manage the Risk of any data loss due to server OS failure or accidental deletion of data or data corruption.
Remember that not all VPS hosting provider provides high-availability features. If you find that your current plan does not provide the level of redundancy you need, you may consider migrating to HA VPS Provider. Cloudtreno HA VPS boosts your server performance and reliability and uptime.
