    The Difference Between Public and Private Cloud

    August 9, 2017 | By Admin |

    What is the difference between public and private cloud?

    Choosing the right cloud solution for your business is a vital part of creating a strong hybrid IT strategy. Providing a balance across competing agendas is critical and aligning the right cloud infrastructure for the right use case can sometimes be a challenge.

    Private Cloud

    A private cloud solution will host your data on a dedicated server with access and management limited to your business only. The network is protected by a secure firewall and offers high performance due to its single usage.

    Customers can customise the control and maintenance of their service. This means you can tailor your infrastructure to meet your business needs and to suit any security or infrastructure requirements you have.

    Public Cloud

    A public cloud solution stores your information off-site on a shared server managed and maintained by the service provider.

    Support and updates are handled by the Cloud Service Provider and services are paid for on a subscription basis, reducing the need to invest large amounts of capital and freeing up your in-house IT resources.

    This gives your business flexibility and allows for quick access to applications and data when testing or as part of a recovery plan. However, it does mean that you have limited control around when and what updates are performed on the system.

    Differences

    Although both public and private cloud offer hosting solutions, the way they operate differs when it comes to security, performance, and control.

    Companies who require a high level of performance, control, and security should opt for a private cloud solution, whereas those who are perhaps smaller companies could consider a public cloud.
