You’ve almost certainly heard about the benefits that come with cloud migration, but when people talk about ‘the cloud’ they aren’t just talking about one single program. There are several different kinds of cloud, and one of the most common distinctions is between public clouds and private clouds.
Public clouds are operated by a third party for use by individuals or other companies, and you can typically just sign up online – Dropbox is probably the most well-known public cloud. A private cloud is owned and operated by a single organisation. It can be set up by an external company, but its use is restricted to employers and customers of a single business.
You’ll probably have been told that private clouds are superior since services can be tailored more around your needs, but there are plenty of benefits that come with opting for a public cloud.
Here are just a few.
One of the major drawbacks of private cloud services is that they typically involve a very steep initial outlay. If your business is on the larger side, this considerable initial expense will eventually pay for itself, but that’s not the case for the majority of small and medium sized businesses. Paying monthly feels far more manageable than coming up with a large initial payment, especially when you’re just getting started.
Private cloud services can be closely tailored around your needs, but problems often arise when those needs change: private cloud services lack the scalability of public cloud services. If you need more data, you should be able to expand very quickly on a simple pay-as-you-go scale. Public clouds are huge – it would be almost impossible to consume the entire capacity of a public cloud.
If you need to handle extremely sensitive data, it makes sense to go for a private cloud service since the chance of hacking drops dramatically. However, you’re actually less likely to have your data temporarily lost when you use a public cloud. Because public cloud services call upon a vast network of servers, a failure in one data centre doesn’t mean that the entire network goes down.
