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 for my business? Our guide shows a comparison of cloud vs on premise with a focus on security and cost.

When thinking about the differences between 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.

The difference between on-premise and cloud is essentialy where this hardware and software resides. On-premise means that a company keeps all of this IT environment onsite either managed by themsleves or a third-party. Cloud means that it is housed offsite with someone else responsible for monioring and maintaining it.

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

So is Cloud better than on-premise?

Whilst its clear that the Cloud offers a range of benefits, every business is different and has different priorites. At EBC Group we believe in offering the right solution for your business and can offer a range of managed services including Cloud Solutions from our own dual data centres, on-premise solutions or a mixture of both.

Cloud services are attractive because they enable businesses to transfer the responsibility 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.

Different Infrastructure Setups Section

Different Infrastructure Setups

On-premises vs Public Cloud vs Private Cloud


All services are run, managed and maintained from within the business On-site hardware, servers and PBX phone system. Broadband link to the internet and calls made over ISDN30 lines. Back-up via tapes or network A traditional on-premise setup is expensive to run, manage and maintain. It’s less flexible and difficult to scale to multiple sites as your business grows.

Public Cloud

Connection to providers data centre is via the internet meaning you risk losing everything if you lose access Reliant on businesses own firewall protection against internet viruses and spam Data back-up only, does not provide access to applications or instant availability of data.

Private Cloud

Dedicated leased line into Private Cloud Dedicated infrastructure and/or hosted environment within the private cloud Fully replicated to a secondary data centre providing virtual machine, back-up and disaster recovery solution. Access to the internet via EBC Group’s secure leased line Flexible and inexpensive to scale to multiple sites

Why cloud infrastructure is like ordering pizza

Believe it or not, the basics of cloud computing and the differences between on-premise, infrastructure-as-a-service (IaaS), platform-asa-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.

Pizza as a service

If the diagram is changed into IT environments and the same rational is used, it starts to become clearer how the 'Pizza as a Service' translates into different cloud services.

Cloud as a Service

The ‘Pizza as a Service’ example is quite simple and can be explained as:

1. Make at home

  • You can make a pizza at home where you’re responsible for buying all of the ingredients including making the dough and providing the equipment and energy to cook the pizza.

2. Take and Bake

  • You can purchase a pizza from the supermarket but cook and eat it at home.

3. Pizza delivered

  • You can have pizza delivered to your home and just provide the environment to eat it in.

4. Eat out

  • You can go to a pizza restaurant that provide everything you need.
