Colo-Public and Private Cloud
Hybrid cloud computing
Many organizations choose a hybrid cloud approach due to business imperatives such as meeting regulatory and data sovereignty requirements, taking full advantage of on-premises technology investment, or addressing low latency issues.
The hybrid cloud is evolving to include edge workloads as well. Edge computing brings the computing power of the cloud to IoT devices—closer to where the data resides. By moving workloads to the edge, devices spend less time communicating with the cloud, reducing latency, and they are even able to operate reliably in extended offline periods.
The benefits of a hybrid cloud platform
A hybrid cloud platform gives organizations many advantages—such as greater flexibility, more deployment options, security, compliance, and getting more value from their existing infrastructure. When computing and processing demand fluctuates, hybrid cloud computing gives businesses the ability to seamlessly scale up their on-premises infrastructure to the public cloud to handle any overflow—without giving third-party datacenters access to the entirety of their data. Organizations gain the flexibility and innovation the public cloud provides by running certain workloads in the cloud while keeping highly sensitive data in their own datacenter to meet client needs or regulatory requirements.
This not only allows companies to scale computing resources— it also eliminates the need to make massive capital expenditures to handle short-term spikes in demand, as well as when the business needs to free up local resources for more sensitive data or applications. Companies will pay only for resources they temporarily use instead of having to purchase, program, and maintain additional resources and equipment that could remain idle over long periods of time.

Advantages of the hybrid cloud:
Control— your organization can maintain a private infrastructure for sensitive assets or workloads that require low latency.
Flexibility— you can take advantage of additional resources in the public cloud when you need them.
Cost-effectiveness— with the ability to scale to the public cloud, you pay for extra computing power only when needed.
Ease— transitioning to the cloud doesn’t have to be overwhelming because you can migrate gradually—phasing in workloads over time.
Understanding your deployment options—
Public cloud, private cloud, or hybrid cloud?
There are three different ways to deploy cloud services: on a public cloud, private cloud, or hybrid cloud. Which deployment method depends on your business needs.
What is a public cloud?
Public clouds are the most common type of cloud computing deployment. The cloud resources (like servers and storage) are owned and operated by a third-party cloud service provider and delivered over the internet. With a public cloud, all hardware, software, and other supporting infrastructure are owned and managed by the cloud provider. Microsoft Azure is an example of a public cloud.
In a public cloud, you share the same hardware, storage, and network devices with other organizations or cloud “tenants,” and you access services and manage your account using a web browser. Public cloud deployments are frequently used to provide web-based email, online office applications, storage, and testing and development environments.
Advantages of public clouds:
Lower costs— no need to purchase hardware or software, and you pay only for the service you use.
No maintenance— your service provider provides the maintenance.
Near-unlimited scalability— on-demand resources are available to meet your business needs.
High reliability— a vast network of servers ensures against failure.
What is a private cloud?
A private cloud consists of cloud computing resources used exclusively by one business or organization. The private cloud can be physically located at your organization’s on-site datacenter, or it can be hosted by a third-party service provider. But in a private cloud, the services and infrastructure are always maintained on a private network and the hardware and software are dedicated solely to your organization.
In this way, a private cloud can make it easier for an organization to customize its resources to meet specific IT requirements. Private clouds are often used by government agencies, financial institutions, any other mid- to large-size organizations with business-critical operations seeking enhanced control over their environment.
Advantages of a private cloud:
More flexibility— your organization can customize its cloud environment to meet specific business needs.
More control— resources are not shared with others, so higher levels of control and privacy are possible.
More scalability— private clouds often offer more scalability compared to on-premises infrastructure.
Frequently asked questions
What are examples of the hybrid cloud and public vs private clouds?
Some practical examples of the hybrid cloud in action:
- Many customers take advantage of the hybrid cloud to achieve global scale, increased reliability, AI-enabled security, and cost savings offered by the public cloud. In highly regulated industries, data residency requirements may mandate that certain sets of data must be kept on-premises, while other workloads can reside in the public cloud.
- If an application resides on-premises or in a private cloud, sudden spikes in demand may overload the capacity—such as season events like online shopping or tax filing. When demand spikes, organizations can tap into additional computing resources in the public cloud, sometimes called “cloud bursting”—where the hybrid cloud environment allows the on-premises infrastructure to “burst through” to the public cloud.
