Earth View, Public/Private Clouds

If you’ve started a journey to the cloud, you may be facing the difficult decision of whether to choose public or private cloud for you IT infrastructure. We often hear over-simplified truisms like, “Public cloud is for modern workloads, and private cloud is for legacy workloads,” or, “the public cloud is risky, but private clouds are secure.” In fact, in a recent study, 4 out of 5 respondents considered data security to be problematic in the public cloud!

In reality, cloud environments are incredibly pliable and customisable. Organisations use cloud for all types of workloads. The important part of your cloud journey is finding the best fit for what you hope to achieve through cloud hosting. So let’s clear up some of these misconceptions so that you can make better decisions for your business!

Essentially, Public Cloud is a computing service model used for the provisioning of storage and computational services to the general public over the internet.


  • Dynamic & elastic workloads do well on the public cloud, where you can scale up or down at a moment’s notice
  • Utility model – the public cloud typically operates on a pay as you go model, which is economical if you are frequently building up or taking down development servers on a regular basis
  • Multi-tenant environment allows for shared hardware and servers, so you can save on direct hardware investment
Myth: The public cloud is always un-secured.
Reality: The public cloud is likely to be more secure than your legacy systems!

Your legacy systems may hide many vulnerabilities, like lapsed software updates. Public cloud environments are monitored continuously and updated regularly. Unless you are under strict regulations, a public cloud will likely meet your security needs.

Private Cloud Security

Essentially, Private Cloud is a model of cloud computing where IT services are provisioned over private IT infrastructure for the dedicated used of a single organisation.


  • Stable and predictable workloads are great in a private cloud, where they can be continuously monitored and isolated from more variable workloads
  • Compliance laws or corporate policies may require data to be kept in a private environment
  • Single-tenant environment means that the hardware, storage and network are all dedicated to you
Myth: You only need one cloud strategy
Reality: Don't ignore your wide variety of options! Investigate the benefits of a VIrtual private cloud or a hybrid solution.
