what is cloud computing
What is Cloud Computing
  • Provides everything: computing power, computing infrastructure, applications, business processes, personal collaboration, as a service to a user wherever and whenever they may need
  • Definition from National Institute of Standards and Technology (NIST)
    • Model for enabling convenient, on-demand network access to a shared pool of configurable computing resources that can be rapidly provisioned and released with minimal management effort of service provider interaction
  • Pay-per-use computing model in which customers pay only for computing resources they need
what is cloud computing cont
What is Cloud ComputingCont.
  • Potentially growing to a revolutionary concept that could dramatically impact all areas of the IT world
    • Network design
    • Applications
    • Procedures
    • Personnel
  • May even come down to distinguishing computing as “pre-cloud” and “post-cloud”
  • Could be defined as set of hardware, networks, storage, services, and interfaces combined to deliver aspects of computing as a service.
how cloud computing can be used
How Cloud Computing can be Used
  • Stores data, applications, software, and services on group of computers that act as equipment to deliver software and data to end user.
  • Allows businesses or users to remotely manage, store, customize software or services from any device with Internet access
  • Businesses can meet with clients from all over the world in real time video
  • Employees can work from home with access to all business related software, documents, information
characteristics of cloud computing
Characteristics of Cloud Computing
  • On-demand self-service
    • Users can automatically increase or decrease their resources with out having any human interaction from a service provider
  • Universal client support
    • Any network device such as desktop, laptop, smartphone, or tablet can access the cloud for resources
  • Invisible resources pooling
    • Resources pooled together to serve multiple, simultaneous consumers dynamically assigned or reassigned according to their needs. Customers have no control/knowledge or physical location of resources.
characteristics of cloud computing cont
Characteristics of Cloud Computing cont.
  • Immediate elasticity
    • Computing resources can be increased or decreased quickly to meet demands
  • Metered services
    • Fees based on the computing resources used by consumer
  • Storage
    • Less expensive
    • Off-site location
    • Increase office space and hard drive space
cloud computing service models
Cloud Computing Service Models
  • Cloud Software as a Service (SaaS)
    • The cloud computing vendor provides access to the vendor’s software application running on a cloud infrastructure
    • Application software belongs to vendor providing the cloud service
  • Cloud Platform as a Service (PaaS)
    • Consumer can install and run their own specialized applications on the cloud computing network
    • Customer controls deployment of applications, but do not manage/configure any underlying cloud infrastructure (network, servers, operating systems, storage)
cloud computing service models cont
Cloud Computing Service Models cont.
  • Cloud Infrastructure as a Service (IaaS)
    • Cloud computing vendor lets the customer deploy and run the customer’s own software including operating systems and application
    • Customer has the highest level of control
    • Customer has some control over operating system, storage, and installed applications, but can not manage or control underlying cloud infrastructure
importance of cloud computing
Importance of Cloud Computing
  • Helps in business applications and functionality and usages of computer software
  • Services, applications, data, and other resources available from any device with Internet access. (easy access from anywhere at any time)
  • Helps financially
    • Don’t have to buy cable services with monthly fee
    • Less equipment need to purchase
  • Better tracking of activities
  • Stop technological disasters
    • Data loss
    • Virus
    • System crashes
importance of cloud computing cont
Importance of Cloud Computing cont.
  • Easy to share huge amounts of data, software, applications between business offices
  • Easy access to office data, information to those traveling
  • Services not interrupted
    • Saves time
  • Faster and quicker to solutions helps reduce business risks
  • Still evolving and will only enhance opportunities for the business.
