Public Cloud in Cloud Computing

Introduction

A public cloud is a service provided by a cloud owned and operated by a provider and delivered or used by all via the internet. With the public cloud, all the infrastructure and development are managed by providers, and people can use those services as it is publically available to all. The most convenient public cloud is Microsoft Azure.

Public cloud services are sometimes free or available through some subscriptions. Other than there are pricing schemes and the pay-as-you-go model for big organizations. The public cloud offers scalable RAM, storage, and flexible bandwidth that is universally acceptable and offers automatic data backups.

Public Cloud Infrastructure

Public cloud service is an entirely virtual environment with high network connectivity and performance. The public cloud infrastructure is multi-tenant, allowing sharing of resources with others. Resources like storage, compute power, and memory, are shared between multiple customers; however, they are isolated at the software and logical network levels and do not interfere with each other’s workload. This makes the public cloud infrastructure scalable and durable.
