Cloud computing is a term that is referred to as storing and accessing the data and computing services over the internet. It doesnt store any data on the hard disk of your personal computer. The data can be anything such as files, images, documents, audio, video, and more.
It is the on-demand availability of computer services like servers, storage, networking, databases, etc. The main purpose of cloud computing is to give access to data centers to many users. In cloud computing, users can access data from a remote server.
Let us understand the above example with an example.
Suppose you want to travel somewhere either by bus or train. Then what generally you will do is, you will take a ticket for your destination and hold back to your seat till you reach your destination. In the same manner, other passengers also take tickets and travel in the same bus with you and it hardly bothers you where they go. When your stop comes you get off the bus thanking the driver. Cloud computing is just like that bus, carrying data and information for different users and allows them to use its service at a minimal cost.
Where Cloud Computing used Today?
Nowadays everywhere is Cloud computing. It is a big shift from the traditional way businesses think about IT resources. Every type of Organizations irrespective of size, and industry, they are using the cloud for a wide variety of use cases. Youre may already use cloud computing, even though you dont realize it. For example, if you send emails using an online service like GMAIL, edit documents using Google docs, or stream music and films online, its likely that cloud computing is making it all possible behind the scenes.
But the point that you need to remember, all clouds are not the same, and not one type of cloud computing is right for everyone. Several different models, types, and services have evolved to help offer the right solution for your needs.
For example, financial services companies are using the cloud to power real-time fraud detection and prevention. Healthcare companies are using it to develop more personalized treatments for patients, and video game makers are using it to deliver online games to millions of players around the world.
So, with Cloud Computing, we can do the following operations:
- Developing new applications and services
- Storage, back up, and recovery of data
- Hosting blogs and websites
- Delivery of software on demand
- Analysis of data
- Streaming videos and audios
History of Cloud Computing
Before cloud computing came into existence, there was client/server computing, centralized storage in which all the data, software applications reside on the server-side. If a user wants to run a program or access specific data, then he needs to connect to the server and access the data.
The distributed computing concept came after this, where all the computers are networked together, and resources are shared when needed.
The Cloud Computing concept came into the picture in the year 1950 with accessible via thin/static clients and the implementation of mainframe computers. Then in 1961, John McCarthy delivered a speech at MIT in which he suggested that computing can be sold like a utility like electricity and food. The idea was great, but it was much ahead of its time and despite having an interest in the model, the technology at that time was not ready for it.
In 1999, Salesforce.com became the 1st company to enter the cloud arena, excelling in the concept of providing enterprise-level applications to end-users through the Internet. Then in 2002, Amazon came up with Amazon Web Services, providing services like computation, storage, and even human intelligence. In 2009, Google Apps and Microsofts Windows Azure also started to provide cloud computing enterprise applications. Other companies like HP and Oracle also joined the stream of cloud computing, for fulfilling the need for greater data storage.
Cloud Services providers are the vendors that provide Information Technology (IT) as a service over the Internet. In the market today, there are many cloud providers such as Microsoft, Amazon, Google, IBM, etc.
Cloud computing companies services range from full applications and development platforms to servers, storage, and virtual desktops. Theres are various types of cloud computing services are available in the market.
In this tutorial, we will cover all the concepts and cloud-specific technical terms that are common across all these different cloud providers. So, it doesnt really matter, which cloud provider you want to go with. This course is for anyone who wants to learn and understand cloud computing in general.
Azure is the cloud computing service provided by Microsoft. In this course, we will discuss everything you need to know to build, deploy, and scale applications using Azure.
What you will learn from this course?
You will learn many cloud-related concepts in this course. Some of them are as follows:
- Infrastructure as a service (IaaS)
- Platform as a service (PaaS)
- Software as a service (SaaS)
- Private cloud
- Public cloud
- Hybrid cloud
- Serverless computing and many more concepts
This Cloud Computing Tutorials course is for Whom?
As you know cloud computing is ever-expanding and it is here to stay. It doesnt matter whether you are a software developer, quality engineer, business analyst, software architect, project manager, or head of development. This course is for anyone who wants to understand what cloud computing is and how its changing the world of information technology.
What do we expect from you?
We will do our level best to cover all the cloud-related concepts, but in the meantime, if you have a specific concept in mind that you want me to cover, please leave it as a comment on this Video, and I will surely discuss it in our upcoming Videos in this series.
Before proceeding with this tutorial, you should have basic knowledge of Computers, Internet, Database, and Networking concepts. Terms such as operating system, applications, programs, and their meanings must have to be known before starting this. Such basic knowledge will help you in understanding the concepts very easily.
Finally, your feedback is important and means a lot. So, if you have a few minutes, please let us know your thoughts and feedback on this course.
