We posted previously about how cloud computing – a hosting and virtualization alternative to in-house IT services – is helping companies keep their IT operations up-to-date, without breaking the bank.
There are now multiple solutions that create public, private and hybrid models of cloud computing, each with advantages and limitations, that allow a company to adopt the solution meeting its business and security systems requirements.
With the cloud – or public cloud – model, the services provider holds ownership to the entire physical infrastructure and software. Companies purchasing access to these resources are billed only for time, bandwidth, and storage used.
With the private cloud option, the company hosts its own resources in a dedicated, virtualized environment, for the sole use of its own organization. While this model enables the company to address the risks associated with multiple users and shared resources, it does require a substantial initial investment and subsequent capacity expansion as needed.
The dedicated hosting approach involves non-shared, physical and virtualization environments hosted by an external provider.
The hybrid hosting solution mixes cloud computing and dedicated hosting. It uses a secure, private network to connect services and servers or private clouds within the corporate network, to more flexible resources within the cloud. In this way, the user realizes the low-cost adaptability of cloud computing with the security of its own servers, all through a single management interface.
These different models allow your organization to find the IT services solution that best enables rapid deployment, and reduced-cost maintenance, of productive applications.
So, would a cloud computing solution help your organization meet its data center management needs? We’ll discuss what you should consider, in our next posting.
