Moving to a cloud platform is a key enabler of digital transformation success. Though it may appear simple enough, cloud computing spans a range of different classifications, all of which can be put into 3 categories: Public, Private and Hybrid cloud solutions. This is before we get into additional technical service offering such as Software as a Service (SaaS), Platform as a Service (PaaS) and Infrastructure as a Service (IaaS).

Public Cloud

Public cloud solutions refer to using a public network that is provided over the internet such as OneDrive and iCloud.

Advantages Include:

  • Very little technical knowledge required for deployment as all maintenance is handled by the cloud vendor.
  • High flexibility when it comes to workload scaling through multi-server access.
  • Little or no Capital investment required, when using a public cloud solution, you are not required to invest in expensive hardware or for the deployment and maintenance of the IT infrastructure.
  • Flexible usage cost plans allow organisations to follow lean growth strategies by only paying for what they use.
  • Due to public cloud solutions being distributed across multiple data centres, there is little downtime with the solution being highly reliable.

Limitations:

  • Little control over data security due to never knowing where your data is operating. Though Public Cloud security can often be better than traditional on-premise security solutions as it is always kept up to date, it isn’t quite up to the standard of either a private or hybrid cloud solution.
  • Whilst there are reasonable ‘pay for what you use’ solutions, the cost can add up quickly. As you scale your solution for performance, you may find that you have a higher operational expenditure.
  • Public Cloud solutions offer very limited customisations in terms of the infrastructure itself.

 

Private Cloud

A Private Cloud solution is a solution that is dedicated for use by a single organisation, delivered through a secure, private network.

Advantages Include:

  • A cloud solution can be fully customised to meet the requirements of your business.
  • By having a private cloud, implementing, enforcing and managing data and security and compliance becomes much easier and more reliable than older, traditional on-premise solutions as well as the Public Cloud.
  • As your data remains in a single location that is only accessible by your organisation, behind your own security measures and firewalls, private clouds have far better security than that of public clouds and various on-premise solutions.

Limitations:

  • Private cloud solutions come with a high initial cost investment
  • With a private cloud solution, you are responsible for the operating and maintaining of your data centre as well as IT hardware, security, and compliance.
  • Though the additional security measures of having a Private cloud appeal to most, it may cause mobile users to have limited access when trying to access from a remote location.

 

Hybrid Cloud

As the name suggests, a hybrid cloud solution combines aspects of public and private cloud solutions as well as on-premise infrastructure.

Advantages Include:

  • A Hybrid cloud solution allows additional assurance when it comes to the security of sensitive data as it enables you to store sensitive data on-premise, whilst holding other data in the cloud.
  • Hybrid cloud solutions are often the most cost-effective due to the public cloud element. By utilising a hybrid cloud environment, you can leverage the cost efficiency of the public cloud whilst taking advantage of the increased security of a private cloud.

Limitations include:

  • Although there are long term benefits to having a hybrid cloud solution, the initial deployment cost is much higher than that of a public cloud solution.
  • Cloud and on-premise infrastructure compatibility can pose an issue if not chosen correctly.
