The Basics of Cloud Computing

Introduction

 
Cloud computing is Internet-based computing When cloud computing was provided by many services. Cloud Computing is the use of hardware and software to deliver a service over the Internet. We can access any place anywhere in the cloud. The purpose is storage, database, Virtual machine, etc...
 
Let us discuss the cloud computing services and types one by one.
 

Types of Services cloud Computing

  1. SaaS (Software as a service)
  2. PaaS (Platform as a service)
  3. IaaS (Infrastructure as a service)

Software as a service (SaaS)

 
A service provider provides software and applications through the internet. Most of the common functionalities of desktop applications such as office automation, document management, photo editing, and CRM (Customer Relationship Management).
 
Example: Google documents, Gmail Facebook, Salesforce

Example: Windows Azure, Hadoop, Google AppEngine, Aneka
 

Infrastructure as a Service (IaaS)

 
Infrastructure as a service solution is to deliver infrastructure on-demand in the form of virtual hardware, storage, and networking. It provides high-level APIs.
 
Example: AmazonEc2, S3, V Cloud, Digital Ocean.
 

Types of Clouds

  1. Public Cloud
  2. Private Cloud
  3. Hybrid Cloud or Heterogeneous Cloud
  4. Community Cloud
Let us see the types of cloud one by one
 

Public cloud

 
The public Cloud is easily accessible to public users. A public cloud is meant to serve multiple users, not a single customer. A public cloud can offer any kind of service. For example, the Google App Engine is a public cloud, Amazon Ec2 is a public cloud that provides an infrastructure as a service.
 

Private Cloud

Example: Oracle, Amazon, VMware, DELL, Ubuntu, Microsoft, etc….
 

Hybrid Cloud

 
Hybrid cloud is a combination of two previous Public and private clouds. For example, a public cloud is used to interact with users, the data will through a private cloud.
 

Community cloud

 
The community cloud has multiple administration and different deployment models involving the public, private, and hybrid cloud. Community clouds are distributed systems.
 
Various sectors for Community clouds
  1. Media industry
  2. Public-sectors
  3. Health industry
  4. Scientific research
  5. 5. Energy industries
These are the basics of cloud computing. Cloud computing is paid through rent to use cloud platforms. Service providers are providing free clouds for customers, such as Gmail, Google Drive, etc...
