Expedient | Private vs Public Cloud: It’s All About Control

Private vs Public Cloud: It’s All About Control is brought to you by Expedient.
Cloud computing delivers infrastructure as a service (IaaS) that can be consumed as an operating expense rather than acquired as an asset. The flexibility of moving from capital expense to operating expense provides organizations with a choice between public cloud and private cloud environment options. Choosing between the two—or taking a hybrid cloud approach where workloads operate in both types of environments—requires an understanding of the subtle differences.
In a public cloud, logical computing resources are shared among multiple organizations across the same physical infrastructure and the following feature attributes apply:
- Capacity – The computing, storage and networking resources in a public cloud are shared among multiple organizations and while demand can be matched with supply to ensure the most efficient allocation, those resources are not unlimited.
- Cost – A public cloud delivers a high value return because resources are shared among multiple organizations and can be consumed irrespective of location.
- Control – While public cloud environments deliver control over resource utilization, the shared nature of the infrastructure leaves some elements up to the hosting operator.
- Reliability – High availability configurations in the public cloud provide shared redundancy capabilities.
- Security – Because physical resources in a public cloud are shared, some organizations choose to be selective about which workloads operate here.
In a private cloud, all computing resources are dedicated to a single organization and the following feature attributes apply:
- Capacity – All computing, storage and networking resources in a private cloud are dedicated to a single organization and demand can be matched with supply and to ensure the most efficient allocation.
- Cost – A hosted private cloud can be delivered with little to no capital expense and instead consumed as an operating expense that is predictable over a period of time.
- Control – A private cloud is built to be consumed by a single organization that retains the ability to configure and manage resources without the restrictions that might be imposed in a multi-tenant solution that shares resources.
- Reliability – High availability configurations provide dedicated redundancy in a private cloud because all resources can be assigned in the event of a failure.
- Security – The combination of physical and logical segmentation for resources in a private cloud safeguards the infrastructure at multiple layers which creates additional peace of mind for sensitive workloads.
Making the Decision
A public cloud solution may be right for you if:
- Business growth is dynamic and computing demand fluctuates over time
- Security is an imperative, but workloads can be appropriately segmented to reduce any risk that might be associated with industry or government compliance mandates
- Keeping costs low by taking advantage of economies of scale is appealing
A private cloud solution may be right for you if:
- Business growth is predictable and computing demand is stable over time
- Industry or government compliance mandates limited the feasibility of shared resources
- Accepting higher, but predictable costs to ensure dedicated resources is strongly desired
Some organizations may choose a hybrid approach by deploying workloads across both types of environments.
Public, private and hybrid cloud environments can keep data safe, secure and separate.
