  INTRODUCTIONINTRODUCTION • Cloud Computingprovides us a means by which we can access the applications as utilities, over the Internet. • It allows us to create, configure, and customize applications online. • With Cloud Computing users can access database resources via the internet from anywhere . • They need without worrying about any maintenance or management of actual resources.
• 4.
  What is Cloud?Whatis Cloud? • The term Cloud refers to a Network or Internet. • In other words, we can say that Cloud is something, which is present at remote location. • Cloud can provide services over network, i.e on public networks or on private networks, i.e. WAN or LAN. • Applications such as e-mail, web conferencing, customer relationship management (CRM), all run in cloud.  
• 5.
  What is CloudComputing?What is Cloud Computing? • Cloud Computing refers to manipulating, configuring and accessing the applications online. • It offers online data storage, infrastructure and application. • Cloud Computing is both a combination of software and hardware based computing resources delivered as a network service.

  Basic ConceptsBasic Concepts •There are certain services and models working behind the scene making the cloud computing feasible and accessible to end users. Following are the working models for cloud computing: 1. Deployment Models1. Deployment Models   2. Service Models2. Service Models

  Deployment ModelsDeployment Models   •Deployment models define the type of access to the cloud, i.e., how the cloud is located? • Cloud can have any of the four types of access: Public, Private, Hybrid and Community.
• 10.
  PUBLIC CLOUDPUBLIC CLOUD:The Public Cloud allows systems and services to be easily accessible to the general public. Public cloud may be less secure because of its openness, e.g., e-mail. PRIVATE CLOUDPRIVATE CLOUD: The Private Cloud allows systems and services to be accessible within an organization. It offers increased security because of its private nature. COMMUNITY CLOUDCOMMUNITY CLOUD: The Community Cloud allows systems and services to be accessible by group of organizations. HYBRID CLOUDHYBRID CLOUD : The Hybrid Cloud is mixture of public and private cloud. However, the critical activities are performed using private cloud while the non-critical activities are performed using public cloud.

  Service ModelsService Models   ServiceModels are the reference models on which the Cloud Computing is based. These can be categorized into three basic service models as listed below:
• 12.
  1.1.Infrastructure as aService (IaaS)Infrastructure as a Service (IaaS) 2.2. Platform as a Service (PaaS)Platform as a Service (PaaS) 3.3. Software as a Service (SaaS)Software as a Service (SaaS)

  Software as aService (SaaS)Software as a Service (SaaS) • SaaS model allows to use software applications as a service to end users. • In this we can directly access the commercially available software using the internet without even installing the software. • For Example: Google docs by which online spreadsheets are created for school and office uses.

  Platformas a Service(PaaS)Platformas a Service (PaaS) • PaaS provides the runtime environment for applications, development tools, etc. • PaaS provides all of the facilities required to support the complete life cycle of building and delivering web applications and services entirely from the Internet. • It means Application developers can develop applications on cloud platform without maintaining the resource over the internet

  PaaS ExamplesPaaS Examples

  Infrastructure as aService (IaaS)Infrastructure as a Service (IaaS) • IaaS is the delivery of technology infrastructure as an on demand scalable service. • IaaS provides access to fundamental resources such as physical machines, virtual machines, virtual storage, etc. • Vmware is good example of IaaS by which we can run multiple operating system in single sytem.

  Cloud StorageCloud Storage •Create an Account User name and password. • Content lives with the account in the cloud. • Log onto any computer with Wi-Fi to find your content
• 21.
  AdvantagesAdvantages • Lower computercosts • Improved performance: • Reduced software costs • Instant software updates • Improved document format compatibility • Unlimited storage capacity • Increased data reliability • Universal document access • Device independence
• 22.
  DisadvantagesDisadvantages • Requires aconstant Internet connection • Does not work well with low-speed connections • Features might be limited • Can be slow • Stored data can be lost • Stored data might not be secure
• 23.
  conclusion • Cloud computingis the next big wave in computing. • It has many benefits, like better hardware management, since all the computers are the same and run the same hardware. • It also provides for better and easier management of data security, since all the data is located on a central server, so administrators can control who has and doesn't have access to the files.
