Cloud computing refers to access to IT services (servers, storage, networking, software) via the Internet (the “cloud”) from a provider. The main services offered in cloud computing are SaaS (Software as a Service), PaaS (Platform as a Service) and IaaS (Infrastructure as a Service) or MBaaS (Mobile Backend as a Service). Generally on three levels, the public cloud – accessible via the Internet -, the enterprise or private cloud – accessible only on a private network -, the intermediate or hybrid cloud – which is a mix between the public cloud and the private cloud.Large companies in the information technology and telecoms sector are massively developing cloud computing, ranging from the cloud services mentioned above to the rental of software (cell phone applications, office software, drawing, publishing, etc.), but also content, such as video on demand . Cloud computing technologies have enabled the development of megadata solutions and ubiquitous computing. The Internet of Things and 5G rely on cloud infrastructures. (Wikipédia)
All these clouds presented in the video are not bad but if I had to choose one and I had to recommend it I would choose Azure because very well provided and is a product of the brand that I like a lot I speak about Microsoft! When I was in my old computer training for computer networks I was looking to master Azure and work on it for a year for computer networks in order to show it on my resume and flex as a boss my skills on it x). Now that I changed my training to development I would work on Azure to create web, desktop or mobile apps and I think I would post my projects on GitHub for people to see and improve them.
