What is Cloud Computing?

In cloud computing, we can manipulate, configure and access the hardware and software remotely. In general, cloud computing is accessing and storing the files and databases over the internet instead of accessing it on your computer’s hard drive.

Cloud computing offers platform independence, the software is not required to be installed on any PC. There is portability in cloud computing.

Applications that execute on a cloud are over email or through web conferencing.

Basic Concepts of Cloud Computing

To make cloud computing feasible and accessible to the end users, there are certain services and models:

  1. Deployment Models
  2. Service Models

1. Deployment Models

Bank Exam Preparation - Deployment Models

There are four types of access in the cloud:

  • Public
  • Private
  • Hybrid
  • Community
  • Public Cloud

Public cloud is easily accessible to the general public. A private cloud is operated by the organisation it serves. Public cloud is inexpensive. There are no wasted resources because you pay for what you use.

  • Private Cloud

Private cloud only allows systems and services to be within an organisation. Private cloud is the best for business with dynamic or unpredictable computing needs because they will have control over the environment of the cloud.

  • Hybrid Cloud

Hybrid Cloud is a cloud service which includes both private and public clouds. Hybrid cloud is best for heavy workload because it combines both public cloud and private cloud.

  • Community Cloud

In the Community cloud, the resources are shared between several organisations. It allows several companies to work together on the same platform, where they can share their resources.

2. Service Models

There are three service models:

  • Infrastructure-as-a-Service (IaaS) – Here users are responsible for managing data, applications and runtime. In IaaS, providers manage virtualisation, servers, hard drives, storage, and networking.

Example: (AWS) Amazon Web Services, Microsoft Azure.

  • Platform-as-a-service (PaaS) – PaaS is used for development. With PaaS, one can develop and customise applications. PaaS makes it easy to for development, testing, and deployment of applications.

Example: Apparenda

  • Software-as-a-service (SaaS) – As it is a service based cloud, the cloud provider delivers a complete software to the client. It provides pre-configured hardware resources through a virtual interface. It does not include any Operating System. It allows access to the software only.

Example: Google Apps, Salesforce, Workday.

History of Cloud Computing

The evolution of cloud computing started in 1950 with mainframe computing. Here multiple users are allowed to access a mainframe.

After 20 years around 1970, the concept of virtualisation came. Virtualisation software made it possible to execute one or more operating systems simultaneously in an isolated environment.

Risks related to Cloud Computing

Risks related to Cloud Computing

In some cloud’s data management and infrastructure management is provided only by the third party, so it’s very risky to handover any valuable information to the service providers.

It becomes challenging to switch from one cloud service provider to another.

Sometimes data deletion request is made and it may not get deleted, as backup files are not available at the time of deletion.
