Cloud buzz terms are constantly ringing in the ears of CIOs as organisations endeavour to take advantage of the technology. But what exactly is it? Wikipedia defines Cloud Computing as “… Internet-based computing, whereby shared resources, software, and information are provided to computers and other devices on demand, like the electricity grid.”
Quite simply, cloud computing is the offering of applications and services over the internet.
Public, Private and Hybrid Clouds
A public cloud is a shared infrastructure, where anyone is able to tap into the resources.
A private cloud delivers resources behind a firewall to only one customer, usually on-premise.
It has been said that the term ‘private cloud’ is an oxymoron. Given the two definitions listed above, this may be the case. ‘Shared resources’ and ‘multiple external customers’ are definitely not offered within a private cloud. Private clouds lose so many of the benefits of cloud computing, such as scalability and flexibility.
There are concerns over security within a public cloud – how is my data going to be separated and secure from everyone elses on the same cloud? The term ‘public’ is fairly misleading… yes, you’re sharing a cloud, but there’s no ‘public access’.
Harbour IT’s cloud offering can be described as a Hybrid Cloud. While there are multiple customers on our cloud, each is stringently segregated into their own VRF (Virtual Routing & Forwarding). We use VMware’s vSphere technology – the best in the business.
Unlike many providers, Harbour IT’s data centre is located in Sydney, with a DR site in Melbourne. Both sites boast state-of-the-art security, including biometric hand geometry readers and CCTV and detailed surveillance logs.
