You Might Wonder – What Is Cloud Computer:
#Cloudcomputing is a set of forms that contain certain elements that allows for on-demand, network access, scalability, and shared resources. It's a platform for managing, storing, and processing data online through the internet.
Some of the cloud computing features include the following:
- On-Demand Services – Available when you need it
- Network Access – When using the internet as your medium
- Shared Resources – All resources are gathered together and used by multiple customers
- Scalability - The ability of a computer system to adapt to increasing demands
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:
Amazon EC2, Go Grid, and Rackspace.com.
Here is a short list of some companies that use cloud computing:
iCloud – Cloud from Apple is for Apple products. You can backup and store everything from multimedia to documents online. The content is then smoothly integrated onto your devices.
Amazon's AWS - When you talk about companies using cloud computing, Amazon Web Services leads the pack. It offers IaaS and PaaS to all their customers.
Google Cloud – This cloud platform is universal for Google's enormous ecosystem and for other products such as Microsoft Office. It provides storage of data and collaboration along with other services that are included in their cloud computing suite.
Microsoft Azure – Offered by Microsoft, it provides SaaS, PaaS, and IaaS for its software and developer tools. If you have used Office 365, then you have used SaaS.
IBM Smart Cloud - This offers private, public, and hybrid distribution platforms providing a full range of SaaS, PaaS, and IaaS cloud computing services for businesses. The pay as you go platform generates profits for IBM.
New technology is popping up all over the internet and Cloud seems to be on the rise. This is only scratching the surface on what is already available and what will become available throughout 2017.
