In this tutorial, we will start with what is cloud computing. Introduction to cloud computing and learn various cloud service models which are there in cloud computing. We will also discuss about popular cloud providers in the industry.
Here is highlights of this blog post you will learn.
- Introduction to Cloud Computing
- Cloud Service Models
- Introduction to Cloud Providers
Let’s get started with what is cloud computing.
Cloud computing is the practice of using remote server on the internet for carrying out our task instead of using our own computer. Let’s say for example you want to access your data (your work) from anywhere, any location or any device, you can do this by storing your data on cloud server and get a freedom of accessing your data from anywhere and any location and any device like tablet, mobile or your laptop.
The other benefit of using cloud computing is you get more computer (CPU) power, more resources and it can be added as much as required because cloud computing is a group of computers (servers)
Some of the most popular cloud provider is Google Cloud, Amazon web server (AWS) and Microsoft azure.
You can configure cloud server as per your requirement like selecting CUP, RAM and billing cycle as per your requirement. It’s like renting the sever from cloud provider as long as you want. You can also upgrade/downgrade hardware configuration as those servers are scalable and cancel at any time if you don’t require it anymore.
Few examples of using cloud servers are:
Amazon uses AWS cloud server for amazon prime to store their movies and web series videos. Even Netflix is using AWS for the same.
SalesForce, one of the world’s largest CRM provider, using cloud technology to store applications and customer’s data.
Even Software Company like Adobe has adopted cloud technology and sifted their software from desktop version to online cloud platform to stop software piracy and this also resulted in increasing their review by subscription module.
Cloud Computing Models
There are two types of model cloud computing follows:
- Deployment Models
- Public Cloud
- Private Cloud
- Hybrid Cloud
- Service Models
- Infrastructure as a service
- Platform as a service
- Software as a service

Due to lack of infrastructure, digital will be normal for every organization.
As digital transformation is serving the world with better than ever results, more organizations are moving towards the advantages of cloud and choosing cloud computing is indeed an option better than anything else.
In the public cloud, the service provider offers resources including storage capacity, computing power or infrastructure to the businesses but in the case of private cloud, the organizations can use their own infrastructure.
The Reasons Why Businesses Choose Private Cloud Security and Privacy The most important aspect of using a private cloud is to improve the security level it provides.
Compared to the public cloud, private cloud is more secure and the data is saved and managed on a private network that can’t be accessed by any other organization.
The IT team manages the overall server if it is on-site and the organizations don’t need to worry about the physical security of the infrastructure.
Capabilities are available over the network and accessed through standard mechanisms that promote use by heterogeneous thin or thick client platforms (e.g., mobile phones, tablets, laptops, and workstations).• Resource pooling.
The provider’s computing resources are pooled to serve multiple consumers using a multi-tenant model, with different physical and virtual resources dynamically assigned and reassigned according to consumer demand.
Examples of resources include storage, processing, memory, and network bandwidth.• Rapid elasticity.
To the consumer, the capabilities available for provisioning often appear to be unlimited and can be appropriated in any quantity at any time.• Measured service.
The consumer does not manage or control the underlying cloud infrastructure including network, servers, operating systems, storage, or even individual application capabilities, with the possible exception of limited user-specific application configuration settings.Examples: SaaS: Google Apps, Dropbox, Salesforce, Cisco WebEx, Concur, GoToMeeting• Platform as a Service (PaaS): The capability provided to the consumer is to deploy onto the cloud infrastructure consumer-created or acquired applications created using programming languages, libraries, services, and tools supported by the provider.
The consumer does not manage or control the underlying cloud infrastructure including network, servers, operating systems, or storage, but has control over the deployed applications and possibly configuration settings for the application-hosting environment.Examples: PaaS: AWS Elastic Beanstalk, Windows Azure, Heroku, Force.com, Google App Engine, Apache Stratos, OpenShift• Infrastructure as a Service (IaaS): The capability provided to the consumer is to provision processing, storage, networks, and other fundamental computing resources where the consumer is able to deploy and run arbitrary software, which can include operating systems and applications.
