Microsoft Azure — OptiSol commonly referred to as Azure, is a cloud computing service created by Microsoft for building, testing, deploying, and managing applications and services through Microsoft-managed data centers.
It provides software as a service (SaaS), platform as a service (PaaS), and infrastructure as a service (IaaS) and supports many different programming languages, tools, and frameworks, including both Microsoft-specific and third-party software and systems.
Amazon Web Services (AWS) provides on-demand cloud computing platforms and APIs to individuals, companies, and governments, on a metered pay-as-you-go basis.
The AWS technology is implemented at server farms throughout the world and maintained by the Amazon subsidiary. Fees are based on a combination of usage (known as a “Pay-as-you-go” model), hardware, operating system, software, or networking features chosen by the subscriber required availability, redundancy, security, and service options.
Amazon markets AWS to subscribers as a way of obtaining large-scale computing capacity more quickly and cheaply than building an actual physical server farm.
Microsoft and AWS have similar capabilities. Having said that, one can pick one of these cloud solutions depending on business needs. Both Microsoft Azure and AWS are super scalable cloud solutions that help you meet growing business needs.
