Cloud computing is more than just a buzzword. It’s technology that lets you run your data centre off-site, giving it additional capacity, lower maintenance requirements, and access from anywhere in the world. High Availability (HA) servers are servers with minimal downtime. This is possible because they are equipped with superior levels of redundancy. The principle is simple. Your HA server is paired with redundant/standby servers. If your primary server is down, your system seamlessly switches to your redundant cloud. You’ll barely notice the difference, and the solid redundancy network ensures your tech is never down, regardless of your location, processing volumes, or bandwidth availability.

Amazon Web Service (AWS)

HA servers operate in clusters to ensure redundancy. The process of switching over to a redundant server is called failover, and the larger the cluster, the better your redundancy levels, and the higher your availability. AWS is divided into Availability Zones, and each zone comprises a cluster of multiple data centres. Each of these data centre clusters has its own utility line, flood plain, and redundancy network. This means if any data cluster goes down, your AWS can failover to another data cluster within the same Availability Zone. And of course AWS data centres are built with low latency rates to begin with. All this results in less fuss and more uptime, allowing AWS to dominate the cloud server market. Some of the major benefits include:

  • Scalability and flexibility
  • Commitment-free
  • Security
  • Reliability

Microsoft Azure

Microsoft and Oracle have partnered up to improve Windows Azure, increasing its tools and services. Unlike AWS Availability Zones which each consist of multiple independent clusters, Azure Availability Zones are geographically based, with a single data centre per region. So – for example – a weather phenomenon could affect every portal within that regional cloud. Azure works with most computers, because the bulk of devices run on Windows. However, you may experience difficulty – or at least inconvenience – when you try to work with systems that aren’t directly linked to Microsoft. And while AWS has better backups and less downtime, Azure has more features and options.
