TG 3.1 Introduction to Cloud Computing
- Focuses on IT infrastructure and the evolution of modern IT infrastructure.
IT Infrastructure
- Includes hardware, software, networks, databases, and IT services.
- Also encompasses information system development, security management, and data management.
Evolution of the Modern IT Infrastructure
- The evolution includes stand-alone mainframes, mainframes and dumb terminals, standalone personal computers, local area networks (client/server computing), enterprise computing, and finally cloud computing and mobile computing.
TG 3.2 What Is Cloud Computing?
- Cloud computing characteristics
- Cloud computing provides on-demand self-service
- Encompasses grid computing characteristics
- Grid computing enables organizations to utilize resources efficiently through fault tolerance and redundancy
- Makes scaling up and down computing/data resources simpler.
TG 3.2, Organizational Server Farms (Diagram)
- A diagram is included to illustrate how organizations utilize server farms to facilitate access to data via the Internet.
Cloud Computing (Continued)
- Cloud computing incorporates utility computing characteristics.
- Cloud computing uses broad network access.
- Cloud computing pools computing resources.
- Cloud computing often takes place on virtualized servers, involving server farms and server virtualization.
TG 3.3 Different Types of Clouds
- Public Cloud
- Private Cloud (or Corporate Cloud)
- Hybrid Cloud
- Vertical Clouds
Figure TG 3.3, Public, Private, Hybrid Clouds (Diagram)
- A graphic illustrates the relationship between public, private, and hybrid clouds, involving organizations, the internet, and firewalls.
TG 3.4 Cloud Computing Services
- Infrastructure-as-a-Service (IaaS)
- Platform-as-a-Service (PaaS)
- Software-as-a-Service (SaaS)
Platform-as-a-Service (PaaS)
- Application developers can create and operate software solutions on cloud platforms without managing the underlying hardware and software.
- Scaling computing and storage is automatic to match demand.
- Operating systems can frequently receive upgrades.
- Development teams can work together over distance.
TG 3.5 The Benefits of Cloud Computing
- Positive impact on employees: Accessing information anywhere and on any device.
- Savings: Reduced or eliminated hardware purchases, software installation costs, and software licensing fees.
- Enhanced organizational flexibility and competitiveness: Scaling up or down operations as needed.
TG 3.6 Concerns with Cloud Computing
- Six categories of concerns are identified.
Categories of Cloud Computing Concerns (List)
- Legacy IT systems
- Reliability of the system
- Privacy matters
- Security issues
- Regulatory, and legal considerations
- Criminal use of cloud computing
TG 3.7 Web Services and Service-Oriented Architecture
- Benefits offered by web services for organizations.
- Service-oriented architecture (SOA)
- Web services use four key protocols:
- Extensible Markup Language (XML)
- Simple Object Access Protocol (SOAP)
- Web Services Description Language (WSDL)
- Universal Description, Discovery, and Integration (UDDI)
Benefits Provided by Web Services
- Organizations can utilize existing Internet infrastructure without implementing new technologies.
- Personnel can access remote or local data without needing in-depth knowledge.
- Creating new applications is swift and straightforward.
Service Oriented Architecture (SOA)
- A collection of web services used for developing a firm's IT applications.
- Facilitates quick modifications to application software.
- Enables integration of systems with varied platforms.
- Web services can be reused in diverse applications.
