High Availability in Cloud Computing: What to Know

High availability is important to keep your cloud server up and running. Make sure to ponder over these points to test your cloud provider on HA.)

The availability of the cloud is often the topmost concern in cloud computing. But why does it matter?

This is because it gives you access to your business-critical data and applications.

If your cloud is not available, you won’t be any longer able to access your apps being available through the cloud. Frankly speaking, unavailability means that cloud solutions don’t exist for your business.

After all, High Availability is the capacity and the ability of the system to provide uninterrupted services. The users require the system to be operating 24/7 and therefore, different techniques and technologies required to be implemented.

Cloud computing is vulnerable to failures which stress the need to take care of user’s availability. Different techniques can be incorporated to enhance system availability.

It goes without saying that interrupted operations lead to the loss of infrastructure on any given day. It directly impacts the operations, with users not being able to retrieve mission-critical data or apps.

Based on the size and structure of your business, the cost of lost productivity and missed business opportunities could lead to a greater loss.

Simply put, the more important your cloud-based apps and data are to your business; the more crucial it is to have a cloud solution with high availability. Therefore, whether you’re looking to establish your own infrastructure or use a cloud service provider, availability will always be a topmost priority.

What to Consider When it Comes to High Availability in Cloud

An efficient cloud service vendor will provide you an accurate estimate of their availability when you ask them. Despite that, if you still want to get a close idea of what a cloud service provider’s uptime for their cloud service will be, consider the points given below.


Cloud platforms made for disaster recovery often have a high level of system redundancy, often by having one standby way to keep your apps and data up and running. This ensures total peace of mind as extra support can be used if one goes offline for upgrades or maintenance.

Cloud Security:

Security of the server is another important factor to look for. It also affects the overall uptime of a server. After all, modern businesses are plagued by several threats like hacking. These cyber-attacks can hinder cloud services once they make an inroad to the system. Make sure the server is guarded by multiple firewalls and antivirus programs as well.

Tier IV Data Centres.

The data centre that accommodates your cloud vendor’s servers can also have a big impact on availability. For example, a Tier I data centre is less likely to have much redundancy built in to minimize disruptions. Tier IV data centres have built-in backup systems and redundancy to withstand severe natural disasters.
