The 3 types of Cloud Computing

8 November 2017

By understanding the different types of cloud and looking at what circumstances they can be applied to, you will be able to pick and mix according to your business requirements.

There are three main types of cloud computing – namely publicprivate and hybrid – all working on the basis that you access a combined hardware and software platform through the internet. Being a Cloud Service Provider, If you're unsure about which type best suits you drop us a line and we can help.

Public Cloud

Public Cloud is known as a multi-tenant environment which means the users share resources and the platform hosts more than one client or company.

With Public Cloud you’re essentially buying a secure portion of a huge infrastructure which is shared between multiple companies, and by doing so costs tend to be more affordable. There is also greater flexibility meaning that you can scale the number of servers and resources you use easily and quickly.

Why choose Public Cloud?

The Public Cloud is particularly good for organisations that have lots of data but do not have major privacy or data sovereignty concerns because you won’t necessarily know where in the world your servers are being hosted.

So it suits organisations that for example sell tickets to music or sports events; one-off big data projects and public-facing websites (e.g. Amazon and Google) which contain lots of information. It can be used by both start-ups and established businesses. The pricing for Public Cloud is pretty standard and the virtual machines created for your use are becoming ever more powerful.

Private Cloud

In a private cloud the computing resources – hardware, software and virtual machines – are for the exclusive use of one single organisation, this is known as a single tenant environment (it’s yours and solely for your use). This means you know exactly where your data is stored and you have total control.

Companies can either have a private cloud on-site within their organisation or can host it within a data centre. The Data Centre would provide the building, cooling, power, bandwidth and physical security and being a cloud service provider, Risc IT Solutions would build your servers, security, storage and everything you need from the ground up.

Why choose Private Cloud?

By its very nature a private cloud offers additional security to a public one. It is best for organisations that need to meet specific security and compliance standards or that want to protect their intellectual property. This is particularly relevant to organisations dealing with sensitive data such as those in the healthcare, finance, legal and public sectors and eCommerce organisations who deal with customer payment details.

With private cloud you know the location of where your data is being held so it is important too for organisations which need prove the sovereignty of their data.

Hybrid Cloud

Hybrid Cloud is a combination of computing models. It can mean a mixture of Private Cloud, Public Cloud or on-site computing resources and can be made up of dedicated and virtual machines. Essentially it is the blend of resources that can help an organisation meet any computing requirement.

More and more enterprises are choosing this model because it allows them to place the right application in the right computing environment.

Why choose Hybrid Cloud?

Hybrid cloud can be used to overcome specific challenges. For example, you might need to reduce your overall costs while continuing to use your existing IT infrastructure or you might have sensitive and non-sensitive data that you need to keep separate – say credit card data from marketing documents.

If you are an organisation that suffers spikes in traffic at certain times of the year it can be used to add additional resources at these peak times. Hybrid cloud also allows you to bridge between applications, for instance using an API to connect Salesforce to your own CRM sitting in a private cloud.
