A public cloud is a common term but its working process might not be clear to many. To run the website and application of a business that is already established or is facing some heavy traffic, we need a hosting service. Public cloud is a virtual platform that offers data storage and virtual machines using the cloud computing model and is managed remotely by the provider.

How does it work?

A third-party web hosting provider hosts on-demand scalable and IT resources which are delivered remotely to a client over a network connection. Businesses choose public cloud because of reasons like redundancy, less overhead maintenance, and cost considerations. Once a business chooses a provider, a cloud migration system must be chosen in order to move the data to the cloud of the provider. This migration can be done over the public internet or the provider’s networking service.

Online migration is good for lesser volumes of data while less expensive and faster offline migration is good for a significant amount of data. There are third-party and cloud-native migration tools to help to move the data to the providers like public cloud storage.

Public cloud architecture

For transmitting data, a public cloud which is a fully virtualized environment relies on a high-bandwidth networking system. The same resources are used by the tenants in order to run the workloads on the multi-tenant architecture owned by the hosting provider. The data of the tenants remain logically separated in the cloud.

There are three service models like IaaS or Infrastructure as a service, PaaS or Platform as a service, and SaaS or Software as a service. The service you choose will decide how much control you will have over the cloud. IaaS customers enjoy more control over the cloud than the PaaS and SaaS model users as these are completely managed by the hosting provider.
