Delivered by third-parties, public clouds are the most common form of cloud computing. Hardware and resources are owned and operated by third­ party vendors, and users, such as businesses, simply access services and accounts via a web browser. With minimal maintenance to consider and a high level of reliability, public clouds have been a popular option for businesses for some time now. 

Generally, users are only required to pay for the services they use, so company costs can decrease dramatically. Furthermore, the scalability associated with public cloud computing ensures your company can access on-­demand resources, as and when they’re needed.

However, public clouds may not be suitable for all businesses. When using a public cloud, you’ll be sharing services with other users, so if your firm has to adhere to strict security protocols, using a public cloud may not be appropriate. Although third-party vendors do implement security strategies to protect user data, there are safer options out there.
