What is Hybrid Cloud?

A computer system known as a hybrid cloud involves the usage of both

public and private cloud services. Utilizing the advantages of both kinds of
clouds enables organizations to meet their own demands and wants.

A private cloud infrastructure, which is devoted to a single organization and

gives additional control, security, and flexibility, is used to host some
applications, data, or workloads in a hybrid cloud configuration. Other
workloads, data, or applications may also be hosted concurrently in a public
cloud environment. This environment is shared by many users and provides
scalability, cost-effectiveness, and flexibility.

o The main aim of combining these clouds (Public and Private) is to

create a unified, automated, and well-managed computing
environment.
o In the Hybrid cloud, non-critical activitiesare performed by
the public cloud, and critical activities are performed by
the private cloud.
o Mainly, a hybrid cloud is used in finance, healthcare, and Universities.
o The best hybrid cloud provider companies are Amazon, Microsoft,
Google, Cisco, and NetApp.
Characteristics of Hybrid Cloud:
o Integration: Hybrid cloud enables businesses to combine their current
on-premises infrastructure seamlessly with public cloud environments.
o Flexibility: Hybrid cloud gives organizations better control over their
infrastructure by allowing them to use the public cloud for non-critical
tasks and the private cloud for sensitive applications.
o Savings(Cost): Organisations can benefit from the public cloud's cost
reductions while still preserving control over their sensitive data and
apps by using hybrid clouds.
o Scalability: With a hybrid cloud, resources may be scaled up or down
as needed without the need for extra on-premises infrastructure
investments.
o Security: By retaining sensitive data and apps in a private cloud
environment and utilizing the security features offered by public cloud
providers, the hybrid cloud enables organizations to maintain a high
level of protection for these assets.
o Data Mobility: The hybrid cloud gives organizations more flexibility
and agility by making it simple to move data between public and
private cloud environments. Disaster Recovery: By utilizing a hybrid
cloud, businesses may create a disaster recovery plan that
incorporates both public and private cloud environments, increasing
their resilience and redundancy.
In general, a hybrid cloud gives businesses a chance to profit from both
public and private cloud systems while also addressing some of their
respective drawbacks.

Private and Public Cloud Environments Integration:

A crucial component of hybrid cloud computing is the integration of public
and private cloud systems. Organizations can use hybrid clouds to combine
the advantages of both public and private clouds while yet ensuring
seamless integration between the two setups.

Integration Can be Accomplished using a Number of Methods,

including:

o Virtual Private Network (VPN): VPNs allow data to be transported

between public and private cloud environments while maintaining a
secure and encrypted connection.
o Hybrid Cloud Management Platforms: These tools let you manage
both private and public clouds from a single interface. They give
administrators a unified picture of the complete infrastructure,
enabling them to manage resources, track performance, and impose
regulations across the two environments.
 o Apps can connect with cloud environments through "Application
Programming Interfaces (APIs)"; this enables the development of
hybrid apps that use both public and private clouds.
o Containerization: Applications can now be packaged using
containers to make them portable between many environments,
including public and private clouds.
o Cloud bursting: Based on demand, cloud bursting enables smooth
application scaling across public and private clouds. Control over their
sensitive data and applications in a private cloud environment enables
organizations to benefit from the elasticity of public cloud
environments.

Overall, the success of hybrid cloud computing depends on the integration of

public and private cloud systems. It enables businesses to benefit from both
environments while yet maintaining control over their critical information
and applications.

Advantages of Hybrid Cloud

o Flexibility: Organisations have access to a lot of flexibility because of
hybrid clouds. While keeping mission-critical data and applications on-
premises or in a private cloud environment, they can take advantage
of the scalability and cost-effectiveness of the public cloud for non-
critical workloads.
o Cost Reduction: Businesses can reduce their IT spending by utilizing
the public cloud's cost advantages for less-important tasks while
storing their more crucial and sensitive data and apps in a private
cloud environment.
o Security: Organisations may profit from the advantages of public
cloud environments while still maintaining control over their sensitive
data and apps thanks to hybrid cloud technology.
o Flexibility: Organisations may be more flexible and responsive to
changing business needs using hybrid cloud technology. While
maintaining the security of sensitive data and applications in a private
 cloud environment, they can quickly deploy new applications or
workloads in the public cloud.
o Performance Improvement: By enabling organizations to use the
resources of both public and private cloud environments, the hybrid
cloud can help them perform better.
o Risk Management: Hybrid cloud provides an excellent way for
companies to manage risk.

Disadvantages of Using Hybrid Cloud:

o Complexity: Managing hybrid cloud environments can be challenging,
particularly when combining several cloud environments, networking,
and security.
o Security: Hybrid clouds can provide additional security difficulties,
such as managing identities across several environments and securing
data as it is being transferred across clouds, even though they improve
security for critical data and applications.
o Challenges with Integration: Integrating several cloud
environments can be difficult, particularly when integrating data and
applications.
o Data Sovereignty: When using public cloud environments,
organizations must be aware of data sovereignty standards, especially
if they are using sensitive data that is governed by data residency
rules.
o Vendor Lock-In: When employing hybrid cloud systems,
organizations need to take care to prevent vendor lock-in. To ensure
mobility and prevent vendor lock-in, they should pick cloud providers
that offer open standards and APIs.
o Infrastructure Compatibility: Infrastructure compatibility is the
major issue in a hybrid cloud. With dual levels of infrastructure, a
private cloud controls the company, and a public cloud does not, so
there is a possibility that they are running in separate stacks.
 o Reliability: The reliability of the services depends on cloud service
providers.

Community Cloud
Community cloud is a cloud infrastructure that allows systems and services
to be accessible by a group of several organizations to share the information.
It is owned, managed, and operated by one or more organizations in the
community, a third party, or a combination of them.

Example: Our government organization within India may share computing

infrastructure in the cloud to manage data.

Advantages of Community Cloud

There are the following advantages of Community Cloud -

Cost effective

Community cloud is cost effective because the whole cloud is shared

between several organizations or a community.

Flexible and Scalable

The community cloud is flexible and scalable because it is compatible with

every user. It allows the users to modify the documents as per their needs
and requirement.
Security

Community cloud is more secure than the public cloud but less secure than
the private cloud.

Sharing infrastructure

Community cloud allows us to share cloud resources, infrastructure, and

other capabilities among various organizations.

Disadvantages of Community Cloud

There are the following disadvantages of Community Cloud -

o Community cloud is not a good choice for every organization.

o Slow adoption to data
o The fixed amount of data storage and bandwidth is shared among all
community members.
o Community Cloud is costly than the public cloud.
o Sharing responsibilities among organizations is difficult.
