On Premises vs Cloud

With the increasing adoption of cloud solutions, many organisations are asking what the difference is between cloud and on-premise IT and what is best option for my business? This guide shows a comparison of cloud vs on premise with a focus on security and cost.

When thinking about the differences between an on-premises IT environment compared to cloud, it’s first important to think about what we mean by the environment. Depending on the business this could be at one-site or multiple and could consist of a range of hardware and software including servers, computers or databases.

On-premise vs cloud

So, in simple terms, difference between on-premise and cloud is essentially where your hardware, application and software reside. On-premise means that a company keeps all of this IT infrastructure onsite, which is either managed by themselves or a third-party. With the Cloud it means that it is housed offsite with someone else responsible for monitoring and maintaining it.

On Premises vs Cloud

Cloud services are often seen as attractive because they enable businesses to transfer the responsibility and cost of running on-premise hardware and software to a specialist provider, who manage the hassles and costs that otherwise burden IT departments, such as software upgrades, security patches and hardware maintenance.

Due to its flexibility, reliability and security, cloud can remove the burden of a business having to maintain and upgrade their own systems, which enables them to invest their time and money into concentrating on their core business strategies. The sections below compare the different cloud setups and highlight the advantages and disadvantages of both.

Different Infrastructure Setups

On-premises vs Public Cloud vs Private Cloud

On-premises

With on-premises infrastructure all services are run, managed and maintained from within the business on their own hardware and servers. Some businesses may choose to do this for compliance or security reasons, although often find it’s more expensive and offers less flexibility.

…as a Service

Believe it or not, the basics of the cloud and the differences between on-premise, infrastructure-as-a-service (IaaS), platform-as-a-service (PaaS) and software-as-as-service (SaaS) can be explained by using the example of making a pizza.

In each scenario you’re still having pizza, however in some cases your business takes responsibility and expense for managing all elements of the process, whilst in the latter you let a specialist do the work for you. What’s pizza got to do with IT you may ask?

The benefit of the ‘dining out’ model or SaaS is that your business outsources the entire process to a specialist provider who takes responsibility for everything, including the upfront cost of purchasing the infrastructure, maintaining the equipment, storage, security and running a team of specialists.

So, is Cloud better than on-premise?

Whilst it’s clear that the Cloud offers a range of benefits, every business is different and has different priorities and strategies. As cloud technology has matured it has provided a wealth of new cloud platforms to choose from. Which whilst ideal in providing more options for businesses has also added increased complexity. For advice, read our guide on migtating to the cloud.
