Types of Cloud Services

                           Types of Cloud Services:
                                                           IaaS, PaaS, SaaS

Most cloud computing services fall into three broad categories: Infrastructure as a Service (IaaS), Platform as a Service (PaaS) and Software as a Service (SaaS). These are sometimes called the cloud computing stack because they build on top of one another. Knowing what they are and how they are different makes it easier to accomplish your business goals.

Infrastructure--As--A--Service (IaaS)

The most basic category of cloud computing services. With IaaS, we rent IT Infrastructure -- servers and virtual machines (VMs), Storage, Network, Operating system -- from a cloud provider on a pay-as-you-go basis. To learn more see

Platform--As--A--Service (PaaS)

Platform-as-a-Service (PaaS) refers to cloud computing services that supply an on-demand
environment for developing, testing, delivering and managing software applications. PaaS is designed to make it easier for developers to quickly create web or mobile apps, without worrying about setting up or managing the underlying infrastructure of servers, storage, network and databases needed for development.

Software--As--A--Service (SaaS)

Software-as-a-Service is a method for delivering software applications over the internet, on demand and typically on a subscription basis. With SaaS, cloud providers host and manage the software application and underlying infrastructure and handle any maintenance, like the software updates and security patching. Users connect to the application over the internet, usually with a web browser on their phone, tablet or PC. To learn more, See

Types of Cloud Services: 

Private, Public and Hybrid 


Not all clouds are the same. There are different ways to deploy cloud computing resources: Public cloud, Private cloud, and Hybrid cloud.

Public Cloud

Public clouds are owned and operated by a third-party cloud service provider, which deliver their computing resources like servers and storage over the Internet. Microsoft Azure is an example of a public cloud. With a public cloud, all hardware, software and other supporting infrastructure are owned and managed by a cloud service provider. We access these services and manage our account using a web browser.

Public Cloud

A Private cloud refers to cloud computing resources used exclusively by a single business or organization. A private cloud can be physically located on the company's on-site datacenter. Some companies also pay third-party service providers to host their private cloud. A private cloud is one in which the services and infrastructure are maintained on a private network.

Hybrid Cloud

A hybrid cloud combines public and private cloud, bound together by technology that allows data and applications to be shared between them. By allowing data and applications to move between public and private cloud, hybrid cloud gives businesses greater flexibility and more deployment options.


How cloud computing works

Cloud computing services all work a little differently, depending on the provider. But many provide a friendly, browser-based dashboard that makes it easier for IT professionals and developers to order resources and manage their accounts. Some cloud computing services are also designed to work with REST APIs and a command-line interface (CLI), giving developers multiple options.

                What is Cloud Computing?       Learn the basic of cloud computing terminology and its uses. Simply, cloud computing is the delivery of computing services - Softwares, servers, storage, databases, networking, analytics and more -- over the internet ("The cloud"). Companies offering these computing services are called providers and typically charge for cloud computing services based on usage, similar to how you are billed for water or electricity at home. Still foggy on how cloud computing works and what it is for? This blog is designed to demonstrate the basic cloud computing jargon and concepts and quickly bring you up to speed. Use of cloud computing you are probably using cloud computing right now, even if don't realize it. If you use online service to send email, edit documents, watch movies or TV, listen to music, play games or store picture and other files, it is likely that cloud computing i...

Robotics? Five factors supporting the rapid growth of robotics through 2022 The robotics industry growth has been tremendously high in the recent years. But the next few years are going to buzz with stupendous advancements in the robotic technology. With technological advancements, the robotics industry growth has gone up tremendously. Earlier, the interaction between a machine and a human was boring and limited. But, recent trends have it that a world full of robots can be a lot of fun. Today, robots can verbally interact, lend a helping hand, and also save lives, which probably makes robots more human-like with every passing day. Realizing the potential of robotics, many organizations have taken significant steps to bring robotics into application in diverse and unique fields. For instance, MIT has introduced the world to a soft robotic fish called SoFi to help save the ocean, whereas NASA is all set to send a  swarm of robots to Mars , similar to a swarm of bee...

C And C++ Programming Languages — Biggest Differences And Comparison April 14, 2016 Short Bytes:  C vs C++ — which one is better? What is a procedural programming language and what is a modular programming language? Which one should be used for better and faster output? Well, we answer all the aspects of using C vs C++ against each other in this article. C Programming language is said to be the mother of most of the most famous languages. However, the next generations and child languages took over C very easily. Among all the programming languages, C is the most talked language against all. Let’s take a deeper look into the same and know why and how these languages are different. C vs C++: Comparison and differences Structural or procedural C is a structural or procedural programming language whereas C++ is a modular or an object-oriented programming language. Let’s look at it this way: Let’s imagine, you are building up a house in...
