Cloud Computing and the Internet of Things

cloud service provider (CSP)

company that provides information technology (IT) and information systems resources to the general public over the internet

cloud computing

computing environment in which software and storage are provided as an internet service and accessed by users with their web browser

characteristics of cloud services

on-demand self service, broad network access, resource pooling, rapid elasticity, measured service

Software as a Service (SaaS)

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

Platform as a Service (PaaS)

information systems model in which users are provided with a computing platform, typically including operating system, programming language execution environment, database services, and a web server

Infrastructure as a Service (IaaS)

information systems model in which an organization, including servers, storage devices, and networking components

public cloud computing

service provider organization owns and manages the infrastructure with cloud organizations (tenants) accessing slices of shared resources via the internet

private cloud computing

cloud technology is used within the confines of a private network. single-tenant cloud

hybrid cloud computing

combines elements of both public and private cloud computing, accessed through a private network

elasticity

ability to quickly increase or decrease available cloud resources

vendor lock in

once an organization has gone through the effort required to transition its infrastructure to a public cloud provider, it will likely be reluctant to go through the migration process a second time, even if concerns arise with their current vendor

multicloud

the use of more than one cloud service provider to support applications

solution to both disaster recovery and vendor lock-in challenges

virtual private cloud

organizations have a CSP build and manage their private cloud

autonomic computing

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

key functions of autonomic computing

self-configuring, self-healing, self-optimizing, and self-protecting

distributed

workload must be spread across multiple physical devices and have the ability to be moved seamlessly from one device to another

immutable

system must be incapable of being changed unless the existing environment is erased and a new environment is installed

ephemeral

infrastructure must be short lived

cloud repatriation

moving workloads out of the cloud and back to on-prem infrastructure

Internet of Things (IoT)

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

sensor

device that is capable of detecting or measuring something about its surroundings

smart city

uses data from smart devices combined with artificial intelligence to improve its infrastructure and efficiently manage traffic lights, power plants, water supplies, and other resources

benefits of IoT

reduce costs to achieve a competitive advantage, deepen organizations understanding of consumer preferences and behaviors, improve customer service and experience, improve workplace safety

key benefits of public cloud computing

increased redundancy in the event of a disaster, reduced costs, and flexible computing capacity

Common issues encountered when moving to public cloud computing include complex pricing arrangements, performance issues, inadequate data security, and ______

vendor lock in

With ________ as a Service, the CSP makes hardware available for the customer to use with their own operating system, database, applications, and so on.

Infrastructure

When using_______ as a Service, the CSP provides all the resources needed, including the hardware, network, storage, and applications.

Software

_______ is required for objects with sensors to exchange data with other connected devices.

network connectivity

Automated monitoring with trend analysis and reporting is related to which type of IoT application?

Connect and monitor

Using data to perform predicative analytics and initiate preemptive action is related to which type of IoT applications?

Predict and adapt

Internet of Things (IoT) developers should focus on building in______from the start.

security

When moving to a multicloud environment, organizations must consider the expected performance of its applications, security concerns, ______, availability requirements, and_______

regulatory compliance; total cost savings

When a deviation from cloud policies or from normal configuration occurs, ______ tools are able to restore the system back to the defined baseline without interrupting the workload.

autonomic system

Sahara Inc. moved its infrastructure and data to a public cloud provider. It was a time-consuming process to move over to its current cloud service provider (CSP). Sahara is unhappy with its CSP and would like to switch to another but is reluctant to go through the migration process again. The issue Sahara is experiencing is called _____

vendor lock-in
