Private Cloud: Pros and Cons
If you're setting up a dedicated cloud infrastructure for your business, you're using a private cloud. Whether you manage it yourself or hire a third-party service, whether you host it in a data center or off-premises, it's a private cloud.

advantage of hybrid multi cloud architecture
Safety. Your data and applications remain behind the firewall, accessible only to your business, making private clouds better for processing or storing sensitive data.
Potentially lower total cost of ownership. Operating expenses decrease over time.
Greater control and customization. Adjust your server to your business' preferences.
flexibility. Ability to move non-sensitive data to the public cloud to accommodate sudden bursts of demand on the private cloud.
shortcoming:
higher cost. The initial cost increases and needs to be reimbursed for the cost of the equipment you purchased.
responsibility. For operating and maintaining your own data centers, IT hardware and enterprise software, as well as your own security and compliance.
Less flexibility. Scale up or down IT resources as your needs change.
Is Hybrid Cloud Right for You?
Not everything belongs in the public cloud, which is why so many forward-thinking companies are opting for hybrid cloud services. A hybrid cloud offers the benefits of public and private clouds and leverages the existing architecture of the data center.

A hybrid approach allows applications and components to interoperate across boundaries (e.g., cloud versus on-premises), between cloud instances, and even between architectures (e.g., traditional versus modern digital). Data also requires the same level of distribution and access flexibility. Whether you're dealing with workloads or data sets, in a dynamic digital world, you should plan for the movement of things in response to changing demands. Over time, where applications or data reside today may no longer be the best place for them to live.

A hybrid cloud architecture includes the following characteristics:

Your on-premises data centers, private and public cloud resources, and workloads are bundled under common data management while remaining unique.
You can connect existing systems running on traditional architectures that run business-critical applications or contain sensitive data that might not be suitable for a public cloud.
Hybrid cloud infrastructure is enabled by Data Fabric, which uses a software-defined approach to deliver a common set of data services across any combination of IT resources.
