The world of ‘Cloud’ can be quite confusing. Acronyms like SaaS, PaaS, IaaS, and even XaaS; terms like private and public, cropping up alongside hybrid (a word you’re probably more accustomed to being used by rose growers).

To add to the confusion, and the concern, you’ll likely hear people telling you that you’re already using cloud technology without even realising it, and in the same breath telling you that cloud is insecure.

Now there’s an easy way to dispel the confusion, and put your mind at rest. The Lanrex Cloud Guide 101 that delivers the basics about the cloud, different cloud models and services.

It explains that, in essence ‘cloud computing’ is simply having the software — operating systems and/or applications — and the data for your business running on hardware and storage located in a remote data centre and accessed over the Internet.

It explains how you are most likely already using cloud services. “For instance, when using personal mail accounts such as Gmail and Outlook.”

So what about that strange juxtaposition of cloud types: public, private and hybrid? The guide explains that, in a public cloud, your operating systems, applications and data all reside on hardware shared among many users. The big advantage is that you pay only for what you use.

With private cloud services the hardware is dedicated to you, but by locating in a purpose built data centre you take advantage of its security and redundant power supplies. And you free up space on your premises.

Hybrid cloud is simply a combination of the two.

And those acronyms: PaaS, SaaS: IaaS. They’re short for Software as a Service, Platform as a Service, and Infrastructure as a Service and they denote the different types of services that the cloud can provide.

SaaS is where all cloud computing users share the same software, such as an email system, or accounting software. With PaaS you get access to the CPU, storage and operating system and you choose what applications you run on those.

With IaaS you get the ‘bare metal’: CP and storage. The operating system and the applications are your responsibility. And XaaS? That just stands for ‘Everything as a Service’.

So what combination of public, hybrid and private and PaaS, SaaSand, IaaS is right for you?

The starting point, as the guide explains, is: “What are your business objectives and business plan?” Everything else flows from that: the type of cloud services you need, your security requirements (The guide explains that most cloud services provide a high level of security, but some organisations might be required to keep certain data in-house).

Still hesitant? You shouldn’t be. Many Australian companies have already embarked on the cloud journey.

And Lanrex can help you start your cloud journey.
