AWS Cloud is a pool of configurable computing servers, which are quickly provisioned or released as per the demand or business requirement. AWS Cloud offers native cloud solutions for business applications, financial management, contact centers, content delivery, analytics, etc. It offers computing resources, containers, databases, data lakes, developer tools, front-end tools for web and mobile, serverless computing, storage, etc. It also offers niche solutions including Internet of Things, Machine Learning, AR / VR, migration & transfer, and much more.

AWS Cloud Computing is used by all large cap, mid cap, and MSMEs. The most prominent Cloud use cases are for application development & testing, big data analytics, highly available customer facing web applications, data storage & back-up, disaster recovery & business continuity planning, and collaboration. Industry sectors and businesses that require responsive and reliable web applications, such as healthcare & insurance, banking financial services & insurance, and AR / VR gaming are the early adopters of the Cloud paradigm.

The benefits of AWS Cloud Computing are agility, democratization of innovation, two-way elastic scaling of resources, containerized migration of traditional business applications, cost savings due to release of CapEx & migration to OpEx, global deployment of applications at the touch of a button, reduced latency due to edge computing, and much more.

AWS Cloud can be adopted in three modes – Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS).

IaaS offers networking, computing resources and data storage. It provides a flexible environment to adopt Cloud and control the Cloud resources. It is more similar to the As-Is IT estate which is deployed to the Cloud through containerization.

PaaS focuses only on deployment and management of native cloud applications as hardware and operating systems are already a part of the PaaS mode of cloud adoption. It resolves the hassles for resource procurement & capacity planning, maintenance, and software & security patching.

SaaS offers end-user applications in pay per use model. It resolves the hassles for service and infrastructure maintenance, such that the end-users can only focus on using the software application.

AWS IAM service allows secure access to AWS resources and services. It allows to create new users, manage groups, create & manage permissions for accessing AWS.
