This is Part 8 of cloud computing tutorial. In our previous video,
we discussed what is a public cloud. In this video, we'll discuss what is a private cloud,
benefits, limitations and use cases, and in our next video we'll discuss what is a hybrid cloud.
As the name implies, a private cloud is private to one organization. In other words,
a private cloud resources and services are used exclusively by one business or organization.
Unlike public cloud, a private cloud resources are not shared by multiple organizations.
All the hardware infrastructure and software are solely dedicated to one organization. The private
cloud is physically located on-premise that is at your organization's on-site data center or it can
also be hosted by a third-party service provider. The important point to keep in mind is, a private
cloud is private, that is all the hardware infrastructure and software are solely dedicated
to one and only one organization in a private cloud. It's very easy to customize the hardware
and software to meet your organization's specific IT requirements. This is because your organization
owns everything, that is the hardware, software and network. So, you have complete control and can
change anything in any way you want to meet your organization requirements. In general, private
clouds are often used by government agencies, financial institutions and any other medium to
large sized organizations with business critical operations that want to have enhanced and complete
control over their cloud environment. Now, let's look at the benefits of a private cloud.
Better security. Resources are not shared with other organizations. So there is better security
with private cloud. Better control. A private cloud belongs to a specific organization. So
you can customize it to meet your specific business needs. Predictable cost. With private
cloud you own all the cloud infrastructure and you're not paying any third party cloud service
provider. So your monthly cooling, energy and maintenance costs are usually predictable. Legal
compliance. When you deal with regulated data, for example financial, health care or credit card
data, there are strict rules around where the data is stored, who can handle and process it
and how it is protected. With the private cloud, you know where your data center is located. So you
know where the data is stored and how exactly it is protected. Next, let's look at the limitations.
With private cloud we have limited scalability. The extent to which you can scale up in a private
cloud is limited by the amount of infrastructure you have. Beyond certain point you cannot scale
up. So the infrastructure is a limiting factor and you may not be able to scale up at will
like in the public cloud. Huge initial capital expenditure. With the private cloud you have
to procure all the cloud infrastructure, hire the workforce to set up and maintain the cloud.
So a private cloud is an expensive solution compared to public cloud alternatives, especially
for short-term projects. Limited access. A private cloud is usually more secure. We use it for
security sensitive applications, because of these high security measures in place mobile users may
have limited access to the private cloud outside of the corporate network. When to use a private
cloud? Well, a private cloud is best suited for highly regulated businesses like financial
and healthcare institutions. Tech companies that require robust security and complete control
over the cloud infrastructure also benefit from the private cloud. Large organizations
that require advanced and custom data center solutions also benefit from private cloud.
In our next video, we'll discuss hybrid cloud. That's it in this video. Thank you for listening.
