Private versus Public Cloud Solutions
Let’s face it, there are BILLIONS of dollars invested in existing IT infrastructure. As more and more enterprise vendors step into the cloud arena, will business in general migrate to the public cloud or opt instead to keep much of their investment in legacy code and custom applications in-house via a private cloud?
The future of cloud computing is up in the air (pun intended)
At this point, we don’t really know how cloud technology is going to shake out. Even if cloud technology gets huge, there’s likely to be a split between private and public clouds for the foreseeable decade. I think as the industry matures, you’ll see commodity services migrate to the public cloud and mission-critical stuff linger in a private cloud.
OK, so what is cloud computing?
Essentially, cloud computing is simply another way of delivering computing resources to run websites and web applications. It allows clients to scale their operations, horizontally and vertically, based on the demands of their users, while ensuring that there are adequate resources to support their apps. You can think of it as technology services delivered on-demand.
Traditional web hosting services are offered in packages with set limits on disk space and data transfer, so as traffic fluctuates, data and transfer needs vary resulting in excess, unused capacity during lean times.
Who could benefit from Cloud Services?
Essentially, everyone could benefit from cloud technology. Businesses that experience seasonal spikes, especially eCommerce retailers, where 80+ percent of their business peaks during holiday seasons, are prime candidates for cloud services.Cloud computing offers those businesses enough services to meet their increased traffic demands, then the option to scale back after the holidays, aligning their operating costs with revenue.
Taking the lead from the BIG vendors
Nearly all of the BIG vendors, from Microsoft to HP and IBM to CISCO, are talking cloud, with most listing their top two priorities as virtualization and cloud computing (virtualization is a cloud enabler). Google and Amazon already host public clouds while vendors like EMC are promoting solutions that virtualize existing servers and storage (private cloud).
Types of private versus public cloud solutions
As the following graphic from Microsoft highlights, there are choices to both private and public cloud services. Of course, these are not all inclusive. In the following months, I’ll address different cloud scenarios, demystifying some of the confusion about what cloud services really offer
