Cloud Computing: Cloud Computing is a type of computing where applications and data are stored on remote servers and accessed through the internet. It is used in a variety of applications, from running entire businesses to powering small applications. It can be used for storage, software development, analytics, and more. It basically refers to the delivery of computing services such as storage, networking, software, analytics, and intelligence over the Internet (the cloud). It allows users to access and use these services on demand, without the need to maintain their own infrastructure or purchase and install the software. Major providers include Microsoft Azure, AWS, and Google cloud.
Cloud computing can be classified into three main categories:
Infrastructure as a Service (IaaS): IaaS provides users with access to computing infrastructure such as servers, storage, and networking over the Internet. Users can rent these resources on an as-needed basis and only pay for what they use.
Platform as a Service (PaaS): PaaS provides users with access to a platform for building, deploying, and managing applications over the Internet. It includes the necessary hardware, software, and infrastructure to develop and run applications, and users do not need to worry about maintenance or support.
Software as a Service (SaaS): SaaS provides users with access to software applications over the Internet. Users can use these applications on demand and do not need to install them on their own devices.
Cloud computing has many benefits, including the ability to scale resources up or down as needed, reduced upfront costs, and increased flexibility and agility. It has become an increasingly popular option for businesses and individuals looking to take advantage of these benefits.
Artificial Intelligence: Artificial Intelligence (AI) is a type of computer programming that enables computers to learn and make decisions. It is used in a variety of applications, from helping robots navigate the world to powering voice assistants and other intelligent software.
