Public Cloud
Public cloud is a computing model where third-party providers deliver IT resources, such as virtual machines, storage, and databases, over the internet on a pay-as-you-go basis. It enables organizations to access scalable infrastructure without owning physical hardware, offering services like IaaS, PaaS, and SaaS. Major providers include AWS, Microsoft Azure, and Google Cloud Platform.
Developers should learn public cloud to build scalable, cost-effective applications that can handle variable workloads, as it eliminates the need for upfront hardware investments and simplifies deployment. It is essential for modern web apps, data analytics, and microservices architectures, allowing for rapid prototyping and global accessibility. Use cases include hosting websites, running big data processing, and implementing serverless functions.
