Cloud Computing Services

platform as a service paas
Platform-as-a-Service (PaaS)
  • PaaS offers several advantages to customers:
    • Application developers can develop and run their software solutions on a cloud platform without the cost of buying and managing the underlying hardware and software layers
    • Underlying computing and storage resources automatically scale to match application demand
    • Operating system features can be upgraded frequently

Platform-as-a-Service (PaaS) (Con’t)
  • PaaS offers several advantages to customers (Con’t):
    • Geographically distributed development teams can work together on software development projects
    • PaaS services can be provided by diverse sources located throughout the world
    • Initial and ongoing costs can be reduced by the use of infrastructure services from a single vendor

TG 3.7

Benefits Provided to Organizations by Web Services

Service-Oriented Architecture

Web Services are based on Four Key Protocols

Web Services and Service-Oriented Architecture

benefits provided to organizations by web services
Benefits Provided to Organizations by Web Services
  • The organization can utilize the existing Internet infrastructure without having to implement any new technologies
  • Organizational personnel can access remote or local data without having to understand the complexities of the process
  • The organization can create new applications quickly and easily
web services are based on four key protocols
Web Services are based on four key protocols:
  • Extensible Markup Language (XML)
  • Simple Object Access Protocol (SOAP)
  • Web Services Description Language (WSDL)
  • Universal Description, Discovery, and Integration (UDDI)
