Cloud Computing Services Models Explanation | IAAS, PAAS, SAAS #Salesforce # CloudComputing

In this video I talk about how you can learn cloud computing from scratch watching over. I have followed similar path while learning cloud and DevOps. If I were to start over again, I would start with fundamentals and learn the cloud. Cloud Computing Introduction, Basic Structure of Cloud Computing | Cloud Computing Lectures Types of Cloud Computing Services: IaaS PaaS SaaS Explained The Three Delivery Models: Cloud computing provides different services based on three delivery configurations. When they are arranged in a pyramid structure, they are in the order of SaaS, PaaS, and IaaS. The Three Services: #SaaS - Software as a Service This service provides on-demand pay per use of the application software for users and is independent of a platform. You do not have to install software on your computer, unlike a license paid program. Cloud runs a single occurrence of the software, making it available for multiple end-users allowing the service to be cheap. All the computing resources that are responsible for delivering SaaS are totally managed by the vendor. The service is accessible through a web browser or lightweight client applications. End customers use SaaS regularly. The most popular SaaS providers offer the following products and services:Google Ecosystem including Gmail, Google Docs, Google Drive, Microsoft Office 365, and SalesForce. #PaaS - Platform as a Service This service is mostly a development environment that is made up of a programming language execution environment, an operating system, web server, and database. It provides an environment where users can build, compile, and run their program without worrying about an hidden infrastructure. You manage the data and application resources. All the other resources are managed by the vendor. This is the realm for developers. PaaS providers offer the following products and services: Amazon Web services, Elastic Beanstalk, Google App Engine, Windows Azure, Heroku, and Force.com #IaaS - Infrastructure as a Service This service provides the architecture and infrastructure. It provides all computing resources but in a virtual environment so multiple users can have access. The resources include data storage, virtualization, servers, and networking. Most vendors are responsible for managing them. If you use this service, you are responsible for handling other resources including applications, data, runtime, and middleware. This is mostly for SysAdmins. IaaS providers offer the following products and services:
