Defining ‘The Cloud’
Definitions of cloud computing change faster than the British weather. Public cloud, private cloud, SaaS, PaaS, on-prem, virtualisation. The list is seemingly endless and certainly overwhelming for any business owner asking themselves how cloud computing could help their business.
As the Business Development Manager here at Fasthosts, I am often in discussions with business owners and IT managers about what these phrases mean and more importantly what opportunities they could bring to their business.
What is public cloud, private cloud and hybrid cloud?
Public Cloud – A cloud that is open to everyone. Lots of users will share the resources of the cloud and this will normally be at a lower cost than private and hybrid solutions.
Private Cloud – A more popular option for organisations that want to benefit from cloud computing but require more security and flexibility than a public cloud. A private cloud is generally restricted to a single customer or trusted community.
Hybrid Cloud – A cloud that joins on-premise infrastructure to private or public clouds, or clouds to each other.
The difference between SaaS, IaaS and PaaS
SaaS (Software as a Service) – This is simply software or an application that you access over the internet and as a result you don’t need to install the software. Google Apps are an example of this.
IaaS (Infrastructure as a Service) – Imagine accessing your desktop PC’s infrastructure – CPU, RAM, network equipment, hard drive – over the internet, add the ability to scale in a “pay for what you consume” model and you have IaaS.
PaaS (Platform as a Service) – Refers to a hosted environment in which developers can build and launch new applications.
Deciding what’s right for you
The great thing about cloud computing is that you can build IT solutions to fit your individual business need. You do not need to fit into a model that “kind of” fits what your company needs. You can decide what elements, hardware, scale, software, applications, redundancy etc. that you need at this moment in time and if in the future this changes then it’s easy to make adjustments.
Now is the perfect time to begin to look at what cloud computing can do for your business. It’s always a good idea to spend a few minutes researching the options and talking to those who are experts in developing IT solutions for business.
