Types of Cloud

 

 

Public Cloud

Public Clouds provide access to computing resources for the general public over the Internet.  However, the resources themselves are owned by the organisation selling the Cloud services. 

 

The Public Cloud provider allows customers to self-provision resources typically via a web-service interface. Customers rent access to resources as required on a pay-as-you-go basis.

 

Public Clouds offer access to large pools of scalable resources on a temporary basis without the need for capital investment in data centre infrastructure.

 

With Public Cloud, infrastructure costs are shared across customers, which result in economies of scale. Data control might be an issue depending on a number of factors, including the type and sensitivity of the data.

 

With numerous Public Cloud options available, these 'off-the-shelf solutions' provide a limited set of functionality and customisation - 'one size fits all.'  Tek-nology Solutions is finding that the majority of its clients cannot meet all their needs through Public Cloud solutions alone; Public Cloud forms a subset of their complete IT solution, for example, Cloud Email and Web Security.

 

 

Private Cloud

Private Clouds offer the same infrastructure as Public Clouds.  They provide users with immediate access to computing resources hosted within an organisation's infrastructure, with the resources dedicated solely for that organisation's use.

 

In comparison to the Public Cloud’s ‘one size fits all’ approach, a Private Cloud is customised to meet the specific needs of the organisation. 

 

Users self-provision and scale collections of resources drawn from the Private Cloud, typically via a web-service interface, just as with a Public Cloud. However, because it is deployed within the organisation's existing data centre, and behind the organisation's firewall, a Private Cloud is subject to the organisation's physical, electronic, and procedural security measures and thus offers a higher degree of security over sensitive code and data.

 

With Private Cloud, the performance of physical hardware can be controlled and maintained by the organisation, and can thus markedly improve data centre efficiency while reducing operational expense.

 

Private Cloud options can be on-premise, where the client resides, or co-located at a third-party data centre.  A permutation of Private Cloud is where Tek-nology Solutions invests in the infrastructure and then rents it back to the client. 

 

 

Hybrid Cloud

Hybrid Clouds are a combination of one or more Public Clouds and one or more Private Clouds.  Technology enables data and application migration between them.

 

Organisations are able to realise the cost benefits associated with Public Cloud and when required, protect confidential information in a customised Private Cloud.
