On-Premise, Colocation, or Public Cloud?
Many CIOs today are deeply worried over the new technological dilemma imposed to them. Companies of all sizes are currently thinking about the role of cloud computing in their IT strategy and how it will alter the way they run their IT operations and businesses. Nebulai chose to write this article to clear up some doubts and pave a path for decision makers to start embracing the possibilities beforehand.
Let us review the three different technology deployment versions (On-Premise, Colocation hosting, and Public Cloud) before we start comparing them.
On-Premise: Relates to some software technology operating in the organization’s physical premises. In other words, software technology located in the organization’s data centers.
Why businesses use this model: One reason was that on-premises deployments were”de facto” deployment model for many organizations for the past few decades. In other words, there was no other alternative. Additionally, the ability to fully control their IT operations was enjoyed by many companies.
Why businesses don’t utilize this model: Although having control over their IT operations was a good advantage for a few, it wasn’t enough to make sure that an organization would efficiently run their IT infrastructure. Companies began to find that scaling their software required IT administrators to forecast demand which led over dedication to resource. Though IT administrators were capable of somehow predicting future demand, they had a lot of operational challenges new infrastructure in time. Also, operate and companies had to buy datacenters in geo locations which included more complexity that is logistical. Thus, many organizations started to attempt to discover or ways to make things more efficient outsource the operations of a number of the infrastructure layers into third party providers. A colocation facility offers direction for the actual state (datacenter construction ), coolingsystem, electricity, racks, power, internet support, etc.. Everything would be then managed by organizations from the racks and upward.
Why companies use this version: Using a colocation facility assisted organizations to possess extra datacenters without having to invest in all the necessary parts up front. Trading capital expenditures for operating expenditures. Nonetheless, these organizations had responsibility of the IT operations and availability of the software deployed in these colocation facilities. The IT services availability did improve but it didn’t fix the challenge of having to rely on the model for its core IT infrastructure elements.
Why firms don’t use this model: Colocation facilities nevertheless had exactly the same limitations as the on premise model, it merely reduced the responsibility and confined the respective limitations to anything below the racks. Therefore, deal with the access to their applications, handle the provisioning of IT infrastructure, and IT administrators still needed to forecast need.
Public Cloud: Relates into some set of interconnected datacenters handled and operated by a third party service provider including Amazon Web Services, Microsoft Azure, Soft Layer, etc.. The service provider then will let networking, calculate, and storage tools charge them typically on a pay-per-use billing model and to firms seeking to leverage their cloud offerings.
Why businesses use this model: Public clouds allow organizations to delegate the management of the majority of the IT infrastructure into a service provider and reduce the complexity of managing multiple datacenters, colocation facilities, etc.. In any case, delegation of responsibility, associations may benefit from the expertise of those service suppliers and get extra IT provisioning benefits such as the ability to set up a server in minutes, shut down servers if not utilizing them without being billed for them, scale over multiple geo locations without having to buy or run several datacenters, leverage technologies which would normally be available to big businesses with heavy investments in IT infrastructure, etc..v
