The document discusses public, private, and hybrid cloud options and which may be best for a business. A public cloud provides resources over the internet on a pay-per-use model but offers less customization and security. A private cloud has extensive security and customization options but requires significant investment. A hybrid cloud combines the strengths of public and private clouds by using public cloud resources during spikes in private cloud usage. The best option depends on a business's needs - public cloud suits smaller businesses needing quick solutions, private cloud suits businesses with regulatory requirements, and hybrid cloud suits businesses with unpredictable traffic fluctuations.

2. Introduction
Public, private, or hybrid?
As the push to the cloud continues in verticals ranging from healthcare to content
streaming, the simple question of “Public, private, or hybrid?” is one being asked with
increasing frequency in IT departments around the world.
Of course, we’re talking about cloud computing.
The decision of whether to deploy a public, private, or hybrid cloud solution can be a
difficult one for even the most experienced companies.
3. Introduction contd..
What are the benefits and disadvantages to each solution? Why might a business
choose public over private cloud, or hybrid over public or private? Is there a “best”
cloud solution?
Below, we’ll take a look at these questions in an attempt to help organizations that are
still in the process of choosing the best solution for their business.
4. Public Cloud
The term public cloud means that all services are provided over the internet, usually
on a pay-per-use model. The public cloud offers great levels of efficiency since
resources can be shared throughout a network.
Data created and submitted by users are stored on the servers of the third-party
provider.
5. Public Cloud contd..
Advantages Of Public Cloud:
Increased network efficiency and more resources
Reduced complexity and lead times (because the architecture is fixed)
Ready-to-go applications used within the public cloud can conform to
the demands of business
6. Public Cloud contd..
Disadvantages Of Public Cloud:
Fewer options for customization
Substantially less secure
Fixed architecture cannot (at times) grow with the needs of the business
7. Public Cloud contd..
Examples Of Public Cloud Vendors:
Google Cloud Engine
Salesforce.com
Amazon AWS
Microsoft Office 365
8. Public Cloud contd..
Is public cloud the best option?
Businesses that are best suited for using the public cloud are ones that need to bring a
product/service to market quickly without the internal infrastructure and support to
build out their own private cloud system. While this may be considered a short-term
solution to compensate for not having said infrastructure, it does provide smaller
companies without IT departments the opportunity to match the deployment speed of
larger companies.

Businesses that are best suited for using the public cloud are ones that need to bring a
product/service to market quickly without the internal infrastructure and support to
build out their own private cloud system. While this may be considered a short-term
solution to compensate for not having said infrastructure, it does provide smaller
companies without IT departments the opportunity to match the deployment speed of
larger companies.
10. Private Cloud
Private clouds are cloud infrastructures that are deployed for a single organization.
These can be managed internally or externally, but all systems and infrastructure are
for the purposes of the organization. When considering a private cloud, the biggest
decision that a business needs to make is the scope of the needed investment to create
the private cloud, as implementation can be very expensive.
11. Private Cloud contd..
Advantages Of Private Cloud:
Extensive security options and capabilities, substantially more than the public
cloud
Availability to the internal network and increased access/communication for
internal users
Can grow with a business and be expanded or changed as needed
12. Private Cloud contd..
Disadvantages Of Private Cloud:
Significant level of engagement from both management and IT departments are
required
Significant investment is required, both to build the private cloud and maintain/grow
it
Does not deliver the short-term solutions – given the required time needed to build it
out – that the public cloud does
13. Private Cloud contd..
Is the private cloud the best option?
Businesses that are best suited for the private cloud are ones that must comply with
regulatory guidelines or have highly volatile applications needed within the cloud.
Additionally, these businesses will be required to install their own servers and storage
hardware that allows for modifications in workloads. Though this can be a significant
investment, it is required if the business deals with regulated data or must comply with
industry rules.
14. Hybrid Cloud
The term hybrid cloud relates to the use of both the public and private cloud by
companies who seek to capitalize on the strengths of both. For example, if a company
houses an application on a private cloud but is in need of more resources during usage
spikes, it would go to a hybrid cloud because the added resources could come from the
public cloud.
15. Hybrid Cloud contd..
Advantages Of Hybrid Cloud:
Best of both the public and private cloud in terms of needed resources
Added accessibility for internal and external users
Security parameters are higher than that of the public cloud
16. Hybrid Cloud contd..
Disadvantages Of Hybrid Cloud:
Inherent inefficiency of monitoring several different security platforms
Customization of rules and policies to govern security and the elements of
infrastructure that do not link between the public and private cloud
Added security risk
17. Hybrid Cloud contd..
Is hybrid cloud the best option?
Businesses that are best suited to the hybrid cloud are those with sites that have
unreliable fluctuations in traffic. With e-commerce, these fluctuations vary greatly
between times of day and seasons in the year. Because the hybrid cloud has the same
security of the private cloud, businesses can utilize both the added resources and the
security to facilitate the needs of their customers. In essence, it is the best of both
worlds.
18. What is Best for your Business?
When asking the question, “Which is better?” the needs of the business and the user
can define the answer. For small organizations, the public cloud is probably the best
options. For larger, more content sensitive companies, the private cloud is more in line
with need. For the best of both worlds and the added time-investment of monitoring
each, the hybrid cloud may be the best choice. By using the needs of the business as a
filter, a company will be better able to evaluate the options well enough to find an
answer.
