The CIO’s Dilemma: On-Premise, Colocation, or Public Cloud?
Many CIOs today are deeply concerned over the new technological problem imposed to them. Companies of all sizes are thinking about the function of cloud computing in their IT strategy and how it will alter the way they run companies and their IT operations. Nebulai chose to write this guide to clear up some doubts and pave a route for decision makers to begin embracing the possibilities.
On-Premise: Relates to some software technology operating in the organization’s physical premises. In other words, software technology deployed at the data centers of the company.
Why companies use this model: One reason was that on-premises deployments were”de facto” deployment model for many organizations for the past couple of decades. In other words, there was no other alternative. Furthermore, the ability to control their IT operations was enjoyed by many companies.
Why businesses don’t use this model: Although having control over their IT operations was a fantastic benefit for some, it wasn’t sufficient to make sure that an organization would efficiently operate their IT infrastructure. Companies began to discover that scaling their software necessitated IT administrators to forecast potential demand which led over dedication to resource. They had a great deal of operational challenges simply provisioning infrastructure in time for the business to react to customer requirements, even though IT administrators were capable of predicting future demand. Also, companies requiring a global presence had to purchase and operate datacenters in several geo places which added more complexity that is logistical. Thus, many organizations began to try to find ways outsource the operations of a number of the infrastructure layers or to make things more effective.
Relates to a datacenter which businesses can utilize to rent rack space needed to deploy their technology infrastructure such as compute, networking, storage, etc.. A colocation facility offers direction for the actual state (datacenter building), cooling, electricity, racks, electricity, internet service, etc.. Organizations would then manage everything up and in the racks.
Why businesses use this model:
Using a colocation facility assisted organizations to possess additional datacenters without needing to invest in all the necessary parts up front. Consequently, trading capital costs for operating expenditures. These organizations still had responsibility of the IT operations and availability of the applications. The overall IT services availability did enhance for many businesses, but it did not solve the challenge of having to trust the model for its core IT infrastructure components.
Why firms don’t use this model:
Colocation hosting facilities still had exactly the same constraints as the on assumption model, it merely reduced the duty and confined the various limitations to anything below the racks. Therefore, manage the access to their software, manage the provisioning of IT infrastructure, and IT administrators still had to forecast need.
Public Cloud: Relates into a set of connected datacenters managed and run by a third party service provider such as Amazon Web Services, Microsoft Azure, Soft Layer, etc.. The service provider will rent calculate, networking, and storage tools bill them typically on a pay-per-use charging model and to companies seeking to leverage their public cloud offerings.
Why companies use this version:
Public clouds allow organizations to delegate the control of the majority of their IT infrastructure into a service supplier and lessen the complexity of managing a number of datacenters, colocation facilities, etc.. Besides, 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 places without needing to purchase or operate multiple datacenters, leverage technologies that would normally be accessible to big companies with heavy investments in IT infrastructure, etc..
