What is a Public Cloud?

A public cloud is a cloud computing environment where resources are shared to multiple organizations over the internet.Additionally, it utilizes the third-party servers to store and manage data effortlessly. Moreover, the public cloud servers are preferred by the companies having low security concerns, and looking for pocket-friendly options.

The same goes with the public cloud environment, you need to pay for the resources that you use i.e. pay-as-you-go pricing model. The public cloud offers robust storage capabilities, and processing power to grow businesses effortlessly.

Disadvantages of Public Cloud

Despite several benefits, there are several disadvantages of public cloud. Let’s check them out!

Data security is one the primary concerns for businesses of almost all sizes. Public cloud is comparatively less secure as it is managed and owned by third-party. Here, the data is shared with other users. Because of its multi-usage, it can be a major concern for the organizations that deal with strict regulatory actions and increases the chances of fraudulent activities.

2. Limited Control

In using the public cloud, you do not have direct control over the physical server, which can limit the control and the customization abilities. Such a significant drawback makes it difficult for organizations that require more configuration flexibility and customized workloads. As a result, it even minimizes the resolution time in complex situations.

3. Long-Term Costs

Generally, the public cloud services work on a pay-as-you-go pricing model. But, without proper monitoring you may end up paying for underutilized resources and unused storage. Leverage using advanced tools and tactics to manage it effectively. On the other hand, it can even happen that using a public cloud for the long-term can seem more expensive.

4. Internet Dependency

This is one of the potential drawbacks faced in case of internet downtime as you will not be able to access the public cloud and its resources.

Advantages of Public Cloud
