Public cloud is today’s most popular and commonly used variant of cloud computing. A public cloud is accessible to everyone and users of a public cloud are sharing the underlying (physical) hardware.
A public cloud provider is responsible for the speed and stability of the infrastructure. This means that you, as a customer, don’t have to worry about the maintenance and updates of the underlying infrastructure. This way, you can fully focus on your virtual platform without having to worry about the hardware used.
Why choose public cloud
As mentioned before, it’s not your responsibility to take care of the underlying infrastructure. In addition, Public cloud brings even more advantages. Launching a virtual machine (VM) can be done in just a few clicks. You can configure a VM yourself so it meets the exact specifications you need (for example, you can run the OS of your choice on your VM). Once online, you only pay for the resources you actually use (accurate to the minute). Public cloud is the ideal solution for organizations with fluctuating demand. In case you need more resources, scaling up can be done very easy and vice versa.
Private vs. public cloud: What’s the difference?
Beside public cloud, you have probably heard of private cloud. By using a private cloud, organizations have full control over the hardware that is used for your cloud environment. A private cloud is delivered to one, and only one, organization. This way the infrastructure is not shared with other organizations. Large organizations who need a high level of control in addition to their infrastructure often choose a private cloud solution.
The maintenance and management of a private cloud is complex and requires a high level of expertise. For this reason organizations often choose a Managed Service Provider (MSP) to help them make the right choices during the process of setting up the cloud and eventually managing their cloud.
Public cloud and OpenStack
Back to the public cloud. If you choose a public cloud provider for your hosting needs, it’s comforting to be able to easily migrate to another provider in case you are dissatisfied. Migrating from one public cloud provider to another becomes easy when they’re using open source technology. Public clouds such as Amazon Web Services (AWS), Microsoft Azure and Google Cloud are built on their own proprietary technology. This makes it difficult for a user to switch from cloud A to cloud B in the future. Fortunately, more and more ‘open’ clouds are being launched, making it easier for organizations to move to the public cloud.
A common technology used by open source minded cloud providers is OpenStack; an open source cloud operating system backed by hundreds of organizations and thousands of contributors. Fuga Cloud is one of these public cloud providers that embraces OpenStack and uses this technology as its basis. This gives our users a sense of freedom. If desired, users of our cloud platform can easily migrate to another public cloud that uses OpenStack technology.
