What Is Private Cloud?
Private cloud refers to cloud computing resources and services made available to a single person or organization. Private cloud, like public cloud, involves the hardware and software used for computing being run and managed in a data center, often on-premise. The user then connects to those resources using a network, such as the internet, enabling them to reduce costs, as well as to enhance scalability and agility.
How Does a Private Cloud Work?
A private cloud works by providing users with dedicated access to physical and software resources housed in a data center. The data center can be on-premise or remote. When you connect to the private cloud, you gain access to all of the resources that have been designated for your company's use.
The architecture related to how to deploy private cloud often depends on virtualization. Virtualization involves using a single computer’s resources to provide IT services to multiple users. For example, suppose there’s a computer in a private cloud with a 20 TB hard drive. If there are 20 users that all want private cloud services, with virtualization all 20 of them could use the same computer—as long as they don’t need more than 1 TB of storage each. Granted, the computer would need to have adequate processing capabilities in addition to storage space, but thanks to virtualization, one machine can be used to serve several private cloud users.
In a business environment, a private cloud experience may feel like an extension of your personal computer. All of the apps, storage, and processing power you need are at your disposal. Further, if you want to upgrade an element of your experience, you can do so in a few hours or less—and for very little money.
What Is a VPC?
What does VPC stand for? VPC stands for virtual private cloud. It consists of a collection of shared resources in a public cloud environment that can be configured so only specific customers can use them. So what is VPC? A VPC is a private cloud hosted within a public cloud. In most situations, because resources can be allocated to your specific organization, working in a virtual public cloud will feel almost exactly like using a regular private cloud.
Is Private Cloud More Secure Than Public Cloud?
The simple answer is yes. Private cloud has the potential to be more secure than public cloud, particularly because you can custom-design the security features you use within a private cloud. When considering how to implement private cloud, security should be one of your primary considerations. In the vast majority of situations, your provider will have more than adequate security measures available, and all you have to do is choose the package that fits your needs.
Also, with a private cloud, fewer people know it exists. Therefore, the number of potential attackers is greatly reduced.
These security advantages of private cloud don’t mean, however, that public clouds are inherently insecure. Public cloud providers have robust security in place that can block a vast number of threats. But if you need to customize your security by using a favorite product, vendor, or particularly stringent security mechanisms, opting for a private cloud may be a better decision.
Why Use Private Cloud?
One of the primary reasons to use private cloud instead of public cloud is that you get a guaranteed allotment of resources dedicated to your organization. There’s no chance of other processes run by another company pulling from your processing power or storage space.
Another consideration when deciding whether to use private cloud services is cost. The expense associated with sourcing and purchasing on-premise computers and peripherals for employees can easily grow beyond the limits of your budget. However, with private cloud services, your monthly subscription fee can avail you of all you need to support many employees' computing needs.
In addition, if you need to use specific software, you may be able to spend less by using a private cloud service. For example, if you’re a small business, and you want to try a certain software solution for a few months, you may have to commit to a year-long subscription or even purchase the software outright if you’re doing it in-house. On the other hand, if you use a private cloud service that makes that software available, you can try it out for a couple of months, see if it works for you, and then move on to something else if it doesn’t suit your needs. In this way, you pay far less than you would have if you had procured the software in-house.
