AWS ─ Cloud Computing

In 2006, Amazon Web Services (AWS) started to offer IT services to the market in the form of web services, which is nowadays known as cloud computing. With this cloud, we need not plan for servers and other IT infrastructure which takes up much of time in advance. Instead, these services can instantly spin up hundreds or thousands of servers in minutes and deliver results faster. We pay only for what we use with no up-front expenses and no long-term commitments, which makes AWS cost-efficient.
Today, AWS provides a highly reliable, scalable, low-cost infrastructure platform in the cloud thatpr multitude of businesses in 190 countries around the world.
What is Cloud Computing?
Cloud computing is an internet-based computing service in which large groups of remote servers are networked to allow centralized data storage and online access to computer services or resources.
Using cloud computing, organizations can use shared computing and storage resources rather than building, operating, and improving infrastructure on their own.
Cloud computing is a model that enables the following features.
  • Users can provision and release resources on-demand.
  • Resources can be scaled up or down automatically, depending on the load.
  • Resources are accessible over a network with proper security.
  • Cloud service providers can enable a pay-as-you-go model, where customers are charged based on the type of resources and per usage.
Types of Clouds:
There are three types of clouds - Public, Private, and Hybrid cloud.
Public Cloud:
In the public cloud, third-party service providers make resources and services available to their customers via the Internet. Customer’s data and related security is with the service providers’ owned infrastructure.
Private Cloud:
A private cloud also provides almost similar features as a public cloud, but the data and services are managed by the organization or bye a third party only for the customer’s organization. In this type of cloud, major control is over the infrastructure so security related issues are minimized.
Hybrid Cloud:
A hybrid cloud is a combination of both private and public cloud. The decision to run on a private or public cloud usually depends on various parameters like sensitivity of data and applications, industry certifications and required standards, regulations, etc.
