What is Cloud Computing?

Cloud Computing refers to maintaining, configuring, and accessing the application online. It offers online data storage, infrastructure and application. Cloud Computing is a combination of both software and hardware based computing resource deliver as network service.

 

Cloud Computing Architecture

Deployment of Cloud Service

Private

Private clouds are built for the exclusive use of one client, providing the utmost control over data, security and quality of service.

Public Cloud:

Public clouds describes the cloud computing in the traditional mainstream.

Hybrid Cloud(Combined Cloud)

Hybrid cloud is combination of public cloud and private cloud.The private cloud is defined as computing services offered either over the Internet or a private internal network and only to select users instead of the general public. Also called an internal or corporate cloud.

 

Service Models

SaaS (software as a service)

SaaS is also known as on-demand-software. It is the software delivery model in which the service is hosted by the cloud service provider.

Pass (platform as service)

It provides operating system and network to its user.

IaaS (Infrastructure as a Service)

Cloud computing offers infrastructure such as processor, memory, network as vendor service.

Virtualization

Virtualization is a technique, which allows to share a single physical instance of resource or an application among multiple customers and organizations

  • Hardware vitualization
  • Operating system virtualization
  • Server virtualization
  • Storage virtualization
Security in cloud

Users of the cloud aren’t aware about the location of the data and ultimately have to rely on the cloud service provider for exercising appropriate security measures. Therefor cloud security is most important.Security in cloud computing is of two types.

 

  • Data securityIt deals with choosing an appropriate location for the data cente so as to protect it form internals threats, different types of wheater conditions, reand even physical attacks that might be destroy the center
  • Network security: Protecting the network over which the cloud is running from various attacks DOS, DDOS, IP Spoofing etc. that intruder may
Why cloud service is popular?
  • Reduce the complexity of networks.
  • Do not have to buy software licenses.
  • Customization.
  • Cloud providers that have specialized in a particular area (such as e-mail) can bring advanced services that a single company might not be able to afford or develop.
  • scalability, reliability, and efficiency
Challenges
  • Lack of standard.
  • Stored data might not be secure. Stored data can be lost.
  • Feature might be limited.
  • Require a constant internet connection. Can be slow.
