For businesses considering deploying a hybrid cloud solution, two primary deployment models have emerged. Both options involve cloud services offered by a third-party service provider, such as Amazon, Google, Microsoft Windows Azure, etc., combined with computing resources that are more closely controlled by the company, and often completely controlled by the company, as in the case of on-premise deployments.
Services offered by a third party can be just a hosted server and other infrastructure that are otherwise fully-maintained by the end-user company, or a complete solution including an application, servers and storage, such as Salesforce CRM, Microsoft Dynamics CRM Online, NetSuite and other hosted CRM and ERP solutions.
Let’s explore the two most common hybrid cloud deployment models:
On-Premise and Public/Private Cloud Hybrid
This hybrid approach is an option for organizations with investments in existing on-premise servers, infrastructure and applications that they wish to maintain, or those that have specialized IT or regulatory requirements that are either not suited for cloud deployment or are cost-prohibitive to migrate.
In this scenario, certain elements of the organization’s IT systems are then typically deployed via either a private cloud hosted by a third-party provider yet completely managed internally by the organization, or they are obtained through a vendor offering a complete solution including servers, infrastructure and applications via the public cloud, such as a cloud-based CRM or ERP. It then typically also requires that the existing on-premise systems and the new private and/or public cloud services be integrated at some level. For instance, a customer account, opportunity or contact managed in the cloud-based CRM should also be accessible from the on-premise system(s).
Private and Public Cloud Hybrid
Another hybrid cloud option includes no on-premise components, and consists entirely of cloud-based solutions (private and/or public). Additionally, the organization can choose whether the private cloud simply utilizes a third-party hosting facility with all management and maintenance performed by internal IT staff, or for the third-party cloud vendor to also provide management services or full turnkey solutions that can only be accessed by a “private” community. Again, integration between the various cloud-based systems is an important consideration, if not always a mandatory requirement.
As pointed out in a Unisys IT survey, many businesses appear to want to migrate to cloud computing at their own pace, so having a variety of options when deploying cloud-based solutions can make the migration as efficient and productive as possible. In the new M-Files white paper, Shaping Your IT Cloud, we highlight considerations for deploying a hybrid cloud solution, and address key questions designed to help businesses evaluate and determine the specific approach that works best for their particular needs and situation.
