Amazon Web Services
Amazon Web Services, Inc. (also known as AWS) is a wholly owned subsidiary of Amazon that offers on-demand cloud computing platform and application programming interfaces (APIs) to individuals, businesses, and government agencies on a metered, pay-as-you-go basis. These online services for cloud computing provide distributed computing processing capability as well as software tools via the use of AWS server farms. One of these services is called Amazon Elastic Compute Cloud (EC2), and it gives customers the ability to make use of a virtual cluster of computers that is always accessible over the internet. The majority of a real computer's capabilities are imitated by Amazon Web Services' virtual computers. These capabilities include hardware central processing units (CPUs) and graphics processing units (GPUs) for processing; local/RAM memory; hard-disk/SSD storage; a choice of operating systems; networking; and pre-loaded application software such as web servers, databases, and customer relationship management systems. All of these capabilities can be found on a real computer (CRM).
Customers receive their services from Amazon Web Services (AWS) through a network of server farms that are spread out across the globe. The fees are calculated using a combination of factors, including the subscriber's chosen hardware, operating system, software, and networking features, as well as the subscriber's required level of availability, redundancy, and security options. This pricing model is known as a "Pay-as-you-go" model. A single dedicated physical computer, a single virtual AWS computer, or clusters of either kind of computer may be purchased by subscribers. While Amazon is responsible for some parts of its subscribers' security (such the physical safety of its data centres, for example), the subscriber is responsible for ensuring the safety of other components of their account (e.g. account management, vulnerability scanning, patching). AWS has operations in various geographic locations across the world, including six in North America.
Amazon advertises Amazon Web Services, or AWS, to its customers as a means of acquiring large-scale computing capability in a more expedient and cost-effective manner than by constructing an actual physical server farm. Even though each service counts consumption in their own unique method, utilisation is the basis for billing for all of the services. According to Synergy Group, as of the fourth quarter of 2021, AWS had 33 percent of the market share for cloud infrastructure, while its two closest rivals, Microsoft Azure and Google Cloud, held 21 percent and 10 percent respectively.
