2. What is Hybrid Cloud?
So, what does an organization do when it wants to leverage the cloud both for its
efficiency and cost saving but also wants security, privacy, and control? It looks at
the Hybrid Cloud which almost serves as a mid-way point between Public and Private
Cloud. The Hybrid Cloud uses a combination of at least one Private and one Public
Cloud. The Private Cloud can be on-premise or even a virtual private cloud located
outside the organization’s data center. A Hybrid Cloud can also consist of multiple Private
and Public Clouds and may use many active servers, physical or virtualized, which are
not a part of the Private Cloud. With the Hybrid Cloud, organizations can keep each
business aspect in the most efficient cloud format possible. However, with the Hybrid
Cloud, organizations have to manage multiple security platforms and aspects and also
ensure that all the cloud properties can communicate seamlessly with one another.
3. A Hybrid Cloud is best suited for:
•Large organizations that want the flexibility and scalability as offered by the public cloud.
•Organizations that offer services for vertical markets- customer interactions can be hosted in
the Public Cloud while company data can be hosted in the Private Cloud.
•need a flexible cloud structure they can adapt to their dynamic workloads
•must process large amounts of data, e. g. for business intelligence (BI) analysis
•use temporary applications or want to introduce new ones quickly
•are subject to very strict legal and data protection regulations but still want to make use of the
flexible public cloud resources and services
•operate globally and do not want to run private clouds or data centers at every site
•do not want to rush anything and prefer to gradually migrate workloads to the cloud.
4. The hybrid cloud advantageously combines private and public clouds and is managed
from a single platform
5. Diff types of cloud Computing
•Public: These clouds are open and accessible to anyone who passes
authentication checks. You'll use strict rules to keep snoops away, of
course. But a public cloud is built with accessibility in mind.
•Private: These clouds are made for sensitive, internal use only. Your
core employees can access the server, but end users or contractors
may not. And no one who doesn't know you can get in. If your
regulatory environment demands strict shielding of sensitive
data (those that work in health care or financial sectors often have this
issue), a private cloud might be a requirement.
•Hybrid: A hybrid cloud blends both public and private clouds. Some
functions happen on private clouds, while others function in public
counterparts. Administrators choose the ideal cloud for each
application, and they can move workloads between the two settings as

7. Advantage of the Hybrid Cloud:
•Well-designed hybrid clouds basically combine the best of a private and public cloud
•Maximum flexibility through the combination of private and public cloud
•Easy increase of compute power to cover demand-based peaks
•On-demand use of public cloud services helps to keep costs under control
•Freedom of choice to use private or public cloud services for dedicated workloads
•Considerable savings potential through elasticity and “on demand” usage concept
8. Disadvantage of the Hybrid Cloud:
•Possibly higher costs if redundancy between cloud models is not avoided or eliminated
•Potentially higher initial conceptual and implementation efforts due to a comprehensive
IT and business process analysis, which should lead to a clear usage concept
•Complexity can be significantly higher, and it can increase the workload on IT resources
if no automation and management tool is implemented or used
9. The Architecture of Hybrid Cloud
The Architecture of Hybrid Cloud Computing comprises 3 major
components-
•The first requirement is public infrastructure as a service which is
AWS, Azure, or Google Cloud Drive.
•The second requirement is a private Cloud.
•The third major requirement is a Wide Area Network (WAN), which is
used to connect the two environments.
A successful Hybrid Cloud is created with the help of hypervisor and the
layers of cloud software. These implementations of software and services
allow instances to migrate between private and public cloud.

11. Summary
Cloud computing will continue to transform how businesses use technology to power their
business. A Hybrid Cloud is a very strong methodology that provides the best in
scalability, security and cost management. The hybrid cloud describes a demand-oriented
combination of private and public cloud environments, which combine the advantages of
the different concepts: on premise or external private cloud (run by a Managed Service
Provider) with a public cloud.
A hybrid cloud architecture comprises an existing private cloud in a “traditional” data
center, one or more public clouds and one or more external clouds, operated in a
Managed Service Provider’s data center. It is imperative to setup the integration as
seamless as possible between the different clouds to ensure a smooth migration,
interoperability, and uniform administration.
