\"What<\/p>\n

No matter what business you\u2019re in, you\u2019re in the data business. Your files are the backbone of your entire operation and losing access to them would be a disaster. As such, it\u2019s perfectly understandable if you\u2019re a little protective of these all-important 1s and 0s. As you begin your search for a data storage solution, understanding some cloud basics can help you make the best decision, and one option that may cross your desk is the private cloud.<\/p>\n

What Is the Private Cloud?<\/strong><\/h2>\n

A private cloud is essentially storage dedicated solely to your organization, but accessible from anywhere. While you can outsource the physical infrastructure of this private cloud to a data center, you do have the option to keep it on-premises. It is a costlier solution than typical public cloud storage, but the trade-off is a higher level of security and control over your data.<\/p>\n

Refresher: What Is the Public Cloud?<\/strong><\/p>\n

By contrast, a public cloud<\/a> storage service would be open to many different organizations or tenants. In a public cloud, tenants share the same physical hardware resources as other tenants, and their individual instances are virtually separated so that one tenant can\u2019t access another\u2019s data. Public clouds typically don\u2019t involve on-premises hardware as everything is managed by the public cloud provider in a data center.<\/p>\n<\/div>\n

Public and Private Clouds: By the Numbers<\/strong><\/h2>\n

In 2020, spending on cloud services grew significantly: Public cloud spending reached $14 billion, and private cloud spending reached $5 billion, according to an IDC study<\/a>. IDC also found that \u201con-premises private clouds\u201d make up nearly two-thirds (i.e., 64%) of private cloud spending.<\/p>\n

According to the Flexera 2021 State of the Cloud Report<\/a>, 97% of respondents used a public cloud and 80% of respondents used a private cloud. As you can see, there is plenty of overlap. Using a public cloud versus a private cloud is not an either\/or decision\u201478% of respondents use both public and private clouds in a hybrid cloud solution.<\/p>\n

Advantages and Disadvantages of Private Clouds<\/strong><\/h2>\n

Both the private cloud and the public cloud have their advantages. Benefits of the public cloud<\/a> include low cost and a higher adoption rate than the private cloud. Therefore, a public cloud can be cheaper to run and it can be easier to find employees who know how to use the public cloud. The high adoption rate also means it is easier to find third-party consultants and experts to provide help when you need it. On the other hand, a private cloud offers advantages such as faster access to data when using on-premises infrastructure and more control over security.<\/p>\n

Private Cloud: Use Cases<\/strong><\/h2>\n
