    • Services Computing
      • Service Oriented Architecture (SOA) has become a key approach to developing and modernizing enterprise applications
      • Web Services , and related XML WS-* standards in development, allow for the implementation of composite services using workflow standards such as the Business Process Execution Language (BPEL)
      • Software as a Service (SaaS) realizes the commercial potential of Services Computing
      • Business Services Networks (BSN) allow SOA solutions with Pay-Per-Use web services
    • Pervasive Computing
      • Ubiquitous connectivity, broadband adoption, mobile Internet access and mobile devices
      • Radio Frequency Identification (RFID), sensors networks, wearable/embedded computers
    • Emergence of Web 2.0
      • Socially-enhanced creativity

      • Semantic web, natural language processing, autonomous intelligent agents, mobile machine learning
  • 5. 2.1. Service Oriented Architecture (SOA)
    • Definition
      • Application development perspective where systems integrate functionality around business processes reusing interoperable services
      • SOA separates functions into distinct units, or services, which developers make accessible over a network in order that users can combine and reuse them in the production of business applications
    • SOA Principles
    • Formal contract
    • Loose coupling
    • Abstraction
    • Reusability

  • 6. 2.2. Software as a Service (SaaS)
    • Definition
      • A business model for hosted software components exposed through Web Service interfaces integrated in applications based on SOA
      • Can be an atomic XML Web Service or a complete BPEL process
      • e.g. Web 2.0 Mash-up, Credit Rating WS, Outsourcing to Payroll BPEL
    • Business Models
      • Provisioning Web Services with a utility computing, pay-per-use, metered, or on demand business model
      • Merging the components of several vendors into a WS-enabled Application Service Provider (ASP)
      • Developing high-performance WS-enabled business processes (e.g., using BPEL) to provide end-to-end and on demand Business Process Outsourcing (BPO)
    • SaaS vs. other On Demand Solutions
      • On Demand is the aggregate category of business models including ASP, SaaS, Utility, in quantity/time as per enterprise demand/needs
      • Utility Computing refers to providing infrastructure services (e.g. grid-based processing power) on pay-per-use or temporary subscription

      • IoT integrated to BSN creates opportunity for mSaaS
      • Need a business-oriented assessment framework
      • Best to adopt a transactional view of the relationships in SaaS commercialization and adoption
    • Identify stakeholder perspectives/viewpoints:
      • Supplier : Independent Software Vendors (ISV)
      • Market : Competition among various ISV’s and Services
      • Adopter : Enterprises, SME’s, End-Users, …
      • Delivery : Ensuring QoS, security, compliance, …
