Private, Public & Hybrid Cloud Computing explained

Cloud Computing is a type of computing that offers agility, scalability and cost-efficiency to the users. Although the word on the streets is ‘Cloud’ the theory/concept behind it is not new… as cloud computing in a nutshell is Virtualisation technology. A cloud environment would effectively provide a pool of computing resources that businesses can utilise when they require. But, there are different types of Cloud Computing – Private, Public and Hybrid.

Private Cloud – This is when a private network(s) or a dedicated hosted infrastructure is only accessible by a single company. Everything within this network is private the hardware, virtual technology and software licenses are all owned by the company the private cloud was built for. Therefore this will give the company total control of the IT environment and the cloud resources available to end users.

Public Cloud – The opposite is the ‘Public Cloud’, which offers IT resources to businesses through a shared infrastructure where all storage and applications are accessed over the internet. A cloud service provider would use virtualisation technology to section or dedicate virtual resources to each business and providing clients with as much or as little as they require. With a CSP cloud infrastructure platform businesses can also deploy their own applications, files, folders, desktops etc for their employees use.

Hybrid Cloud – This is a combination of a private and public cloud and is becoming one of the popular cloud model to go for. For example, a business may have a dedicated infrastructure for business critical applications where all data is stored locally on servers but, they utilise a shared infrastructure for emails. This model allow businesses to take advantage of the scalability and cost-effectiveness of the public cloud but, without the risk of critical applications and data being exposed due to third-parties vulnerabilities.

Windows XP – not long to go until…

From April 8th 2014 the support for Microsoft Windows XP will be ending. So it is nearly time to say goodbye to the popular decade-old operating system.

The end of support means, users will no longer receive anymore security updates. This will lead to security and privacy implications that can significantly impact businesses – without the updates systems may be vulnerable to harmful viruses, spyware and other malicious software.

If using an unsupported operating system, other software and hardware products on the system may also not be support by the vendors either. It will also make it difficult to purchase new software and hardware for the retired Window XP operating system.

Due to the lack of updates, supporting software and hardware, it could lead to users experiencing an increase of downtime and business disruption. To discuss the implications of the end of support for Windows XP in more detail or help with upgrading please contact us today.
