What is Cloud Computing ??
Cloud computing is a model for delivering computing resources (including networks, servers, storage, applications, and services) over the internet on-demand, without direct management by the user. This allows for scalable and flexible use of computing resources, with the user paying only for the resources they use. Some common examples of cloud computing services include Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform (GCP).
AWS Cloud
Amazon Web Services (AWS) is a collection of remote computing services (also called web services) that make up a cloud computing platform, offered by Amazon.com. These services operate from 12 geographical regions across the world. The most central and well-known of these services arguably include Amazon Elastic Compute Cloud (EC2) and Amazon Simple Storage Service (S3).
AWS provides a pay-as-you-go pricing model, meaning that users only pay for the resources they use. Additionally, it offers a free tier for new users, providing a limited amount of free usage of certain services each month.
Azure Cloud
Microsoft Azure is a collection of cloud computing services that make up a cloud computing platform, offered by Microsoft. These services operate from 60+ regions across the world. The most central and well-known of these services include Azure Virtual Machines (VMs) and Azure Storage.
Azure provides a pay-as-you-go pricing model, meaning that users only pay for the resources they use. Additionally, it offers a free tier for new users, providing a limited amount of free usage of certain services each month.
