Are you still skeptical about the safety of sharing details online? Still concerned about uploading and securing data on servers that are also being used by other people from across the world?
You’re not alone. The use of cloud VPS (Virtual Private Servers) still worries some SMEs and mid-size businesses, simply because of the apparent intangibles of other users committing themselves to the same systems. As you’re probably aware, an individual VPS is in itself no more or less vulnerable than a dedicated server, so then becomes hostage to the server in which it exists.
That is why Cloud VPS systems have a lot going for them. For example, the integrated nature of cloud servers means more machines are linked, but that also means more sources of vigilance. If something is wrong, another part of the server can ‘fill the gap’. Let’s say your traditional VPS software fails, knocking you off line until the host technical team can tackle and fix the issue. How much damage and loss of revenue could this cause your small business?
Conversely a cloud VPS is hosted on a hypervisor, which in turn is linked to other hypervisors; should one go wrong, the others step in rapidly to simultaneously protect and host your VPS. The hypervisor software allocates resources between the various VPSs, but at the same time ensures that only that VPSs actual control processes can read from and write to it.
The process of moving from one node to another standby is known as self-healing, and is remarkably resistant to attack. Simply put, the more individual areas of failure that can be identified and removed/protected, the lower the likelihood of that failure taking place. There is strength in numbers.
The thought might occur that the hypervisors themselves might be liable to attack, thus disrupting the entire system. It’s theoretically possible, but at the same time difficult due to a series of network level security features combined with firewalls.
Different servers offer different levels of protection. Most are now using at least some level of AI to combat threats from across the globe; for example, Canadian Web Hosting has recently made its Immunify360 package publicly available for customers, which includes a self-learning firewall and a malware scanning engine.
It’s usually incredibly easy to swap over from one system to another by contacting your host and explaining your requirements. Some hosts allow you to set the number of nodes to scale up the power of your server, or increase the RAM and CPU when the server is experiencing high levels of usage. Clients can monitor the server in real time and contact the host at any time of day, although any host should be able to detect any issues by itself anyway.
There are a host of other steps you can take to protect the business alongside those already in place, such as only running software that is explicitly necessary and using strong passwords. This is good practice 101 and every PC or Mac user should know this already. However, not everyone will be aware of the merits of cloud computing, how to make best use of it, and the level of protection it offers.
