IntroductionPublic, 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.

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.

Public CloudThe 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.

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

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

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.

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.

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

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

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.

Hybrid CloudThe 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.

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

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

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.

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.
