AWS (Amazon Web Services)
AWS (Amazon Web Services) is a division of Amazon (a leading company in eCommerce). Amazon offers on-demand cloud computing platforms including storage, data analysis, etc. under the general heading of AWS. With a massive market share of 35%, Amazon provides its services to people, businesses, and governments. Depending on their needs, Amazon Web Services customers can utilize a whole virtual cluster of machines at any moment. The internet is used to enable the complete service. Amazon's cloud computing infrastructure, AWS (Amazon Web Services), is sizable and constantly expanding. It mixes packaged software as a service (SaaS), infrastructure as a service (IaaS), and platform as a service (PaaS) solutions.
Amazon is regarded as the most potent and adaptable option available when it comes to cloud service providers. The portfolio of Amazon Web Services includes more than 100 services, such as computing, databases, managing infrastructure, developing applications, and security.
Pricing policies at AWS and rivalry
For its cloud services, AWS offers a pay-as-you-go model, either on a per-hour or per-second basis. For clients that prepay in full or commit to one- or three-year usage commitments, there is now the opportunity to reserve a predetermined amount of computes capacity at a discounted rate.
AWS Free Tier is another option for using AWS services if prospective clients are unable to pay the fees. Users can access up to 60 products through the AWS Free Tier, where they can begin creating on the AWS platform and getting hands-on experience with AWS services. Three options are available for the Free Tier: always free, 12 months free, and trials. In the public IaaS market, AWS mainly competes with Microsoft Azure, Google, and IBM.
