When you run a business, you can't have a backup plan for your website. This will help the website work well 24/7 to meet your customer needs. If your website already works on a shared server and you have noticed some performance issues, it may be time to look at High-availability VPS (HA VPS).

What happens when customers visit your website but can't pay because the website is too slow? Worse, when they visit, but the website only displays white pages like? Customers will switch to accessing your competitor's website, and it is obvious.

Many online businesses started on a shared server finally noticed the problems as mentioned above. If your website promotes much revenue for your company, a little downtime can create a big dent in your profits. The high-availability solution will help your VPS avoid downtime.

What is High-Availability?
High-Availability means "High availability," these servers or devices are readily available, avoiding system interruption. To do this, this mechanism requires at least 2 servers running in parallel and continuously. Moreover, when there is a server that has a problem, the other server will replace it to keep the system running.

Traditional VPS
Traditional VPS is often regarded as a stepping stone between a primary shared server and your dedicated device. With a traditional VPS, you will be proactive in using bandwidth and other resources. However, the most significant disadvantage is that when the server goes down, your website will also stop working.

The problem with traditional VPS is still the risk of degradation. That risk is smaller, but it can still happen. The great news is, technology has made it possible to reduce the risk of downtime more. How can this be? To answer that we need to compare traditional VPS and VPS with High-Availability.

Differences between the traditional VPS and High-availability VPS?
Using "clusters" of servers and cloud architecture minimizes the risks associated with both hardware and software problems.

With High-availability VPS, VPS is replicated many times. That way, if the VPS runs faulty, a copy is immediately available instead. This is a high-availability VPS that eliminates unnecessary and expensive downtime.

What is a Cluster Server?
A Cluster Server is made up of nodes, usually physical servers. VPS instances exist on nodes. If a VPS instance on a node fails, it turns up on another node.

In setting up High-availability VPS, replicated VPS instances are available on other nodes in the cluster. Therefore, the main problem has occurred, there will be a backup version. Moreover, everything continued to run smoothly.

What are the benefits of High-availability VPS?
  • All data contained in the VPS instance is protected because it is kept in multiple locations. Problems that occur on VPS will not lead to a serious loss.
  • Customers can access the website quickly and stable, without fear of interruption.
  • VPS copies are usually stored in many clusters, so in case of trouble, there will still be a VPS elsewhere taking over.
  • How do I know if High-Availability VPS is for me?
  • Time is money and downtime is money lost.
This is especially true in today's world, where 81% of consumers are online before making a purchase decision. It doesn't matter which industry you are in. Consumers will see your website whether you offer a real product or a virtual service.

If your website is broken, slow or doesn't work correctly, your customers will leave. Moreover, if you look at the website as your brand, taking the time to consult High-availability VPS server is a must and necessary thing to do today.

In most of case, you need at least 3 servers for high-availability, because the most part of clustering system (distributed storage, database replication, etc) require at least 2 running nodes to work properly.
