chapter 8 cloud computing

Cloud computing

o   Computing an environment in which software and storage are provided as an internet service and accessed with a web browser

advantages to cloud computing

• Business saves on system design, installation, and maintenance

• Increases efficiency

• Reduce costs of new product and service launches

• Employees/customers can access information from any internet-connected computer

types of cloud computing

• public cloud computing

• private cloud computing

• hybrid cloud computing

• automatic computing

public cloud computing services

• Infrastructure as a service

  •   Organization outsource the equipment used to support its data processing operations

public platform as a service

• Users are provided with a computing platform, typically including operating system, programming language execution environment, database services, and a web server

public software as a service

·      Software delivery approach that provides users with access to software remotely as web-based service

Private cloud computing environment

·      Single tenant cloud

·      Organizations often implement due to concerns that their data will not be secure in a public cloud

two types of private cloud computing

·      On-premises private cloud

·      Service provider-managed private cloud

Hybrid cloud computing

• Composed of both private and public clouds integrated through a private network

• Organizations typically use the public cloud to run applications with less sensitive security requirements and highly fluctuating capacity needs but run more critical applications on the private cloud

Automatic computing

• Ability of IT systems to manage themselves and adapt to changes in the computing environment, business policies, and operating objectives

goal of automatic computing

• create complex systems that run themselves, while keeping system complexity unvisble to end user

4 key functions of automatic computing

o   Self-configuring

o   Self-healing

o   Self-optimizing

o   Self-protecting

Internet of things

o   A network of physical objects (things) embedded with sensors, processors, software, and network connectivity capability to enable them to exchange data with the manufacturer of the device, device operators, and other connected devices

sensor

o   a device capable of sensing something about its surroundings such as

• Pressure, temperature, humidity, pH level, motion,, vibration, or level of light

Enabling connectiblty with 5G

• Latest generation of mobiles communications

• High data transfer speed offer high frequencies with minimal delay in response

• Low energy required

• Millimeter wave

• Many devices to transmit data quickly to cloud

Business benefits of IoT

• Reduce costs to achieve competitive advantages

• Deepen the organization’s understanding of consumer preferences and behaviors

• Improve customer service and experience

• Improve work safety
