Summary: Cloud computing means making computers available over the internet for compute power and data storage, without the need for users to set them up or maintain them. Cloud systems can be accessed via public, private or hybrid clouds, with security being an important factor. Cloud computing benefits include reduced costs, quick provisioning and better security. Cloud technology is built using virtualization, multitenancy, loosely coupled architectures and web services. There are different types of cloud services like Infrastructure as a Service (IaaS), Platform as a Service (PaaS), Software as a Service (SaaS) and Backend as a Service (BaaS).

What is Cloud Computing? Cloud computing allows us to access computers over the internet for compute power and data storage, without needing to set them up or maintain them. The simple cloud computing definition is making computers available over the internet. The cloud system provides compute power and data storage that can be accessed via public, private, or hybrid clouds. A public cloud is accessed on the internet and is used by users from multiple organizations, which makes security an important factor. A private cloud belongs to a single organization and is managed by it. A hybrid cloud has the features of both the public and private cloud.
Cloud computing benefits: The main benefit of cloud computing is reduced cost because a user organization need not invest in it's own computers and IT infrastructure. Cloud computing is available quickly, which reduces the time needed to provision new infrastructure. A cloud system may have better security as cloud providers typically have security experts monitoring the systems.
Cloud computing technologies: Next in this cloud computing tutorial, let me mention the main cloud computing technologies. A cloud is built using virtualization, multitenancy, loosely coupled architectures and web services. Virtualization means creating multiple virtual computer devices on a single physical computer device. Multitenancy means multiple tenants (groups of users) using a shared system. Loosely coupled architectures and web services help to build scalable and reliable cloud systems.
Cloud services: There are different types of cloud services like Infrastructure as a Service (IaaS), Platform as a Service (PaaS), Software as a Service (SaaS) and Backend as a Service (BaaS). IaaS provides APIs to access computation resources and data storage with scaling capabilities. PaaS provides a development environment with an operating system, programming language support, database server and web server. SaaS provides applications that users can configure but not install any software. BaaS provides compute power, data storage, notifications and integrations with social media.
Conclusion: Cloud computing is a component of the fourth industrial revolution, enabling organizations to access the latest technologies without needing advanced skills or IT infrastructure. By using cloud computing, organizations can reduce costs, improve efficiency and access the latest technologies with ease. It is changing the way businesses operate and helping to drive innovation across industries. In the current fourth industrial revolution, cloud computing is set to play an increasingly important role in driving innovation and transforming the way we work.
