what is one of the biggest challenges when moving to the cloud for company’s data
security
e-discovery involves
identifying, collecting, and producing information from archived email, files, and documents in cloud storage, collaboration apps, and other cloud services
define cloud computing
a computing environment where software and storage are provided as an Internet service and are accessed with a Web browser
cloud computing can be deployed in several different ways…
public cloud computing
private cloud computing
hybrid cloud computing
define public cloud computing
a computing environment in which a service provider organization owns and manages the infrastructure (including computing, networking, storage devices, and support personnel) with cloud user organizations (called tenants) accessing slices of shared resources via the Internet.
public cloud computing can deliver…
increasing amounts of computing, network, and storage capacity on demand, without requiring any capital investments on the part of the cloud users
benefits of public cloud computing
reduced costs
organizations avoid large, up-front investments in hardware
flexible computing capacity
should computing needs change, cloud computing service provider can deliver more or less capacity
increased redundancy in the event of disaster
providers operate multiple data centers distributed geographically
Public cloud computing can be divided into three main types of services…
infrastructure as a service (IaaS)
platforms as a service (PaaS)
software as a service (SaaS)
define infrastructure as a service (IaaS)
organization outsources the equipment used to support its data processing operations
define platforms as a service (PaaS)
users are provided with a computing platform, typically including operating system, programming language execution environment, database services, and a Web server
define software as a service (SaaS)
software delivery approach that provides users with access to software remotely as a Web-based service
issues with the public cloud computing
complex pricing arrangements
wide variations in performance over time
inadequate data security
vender lock-in
define private cloud computing environment
single tenant cloud
why do organizations often implement private cloud computing environments
concerns that their data will not be secure in a public cloud
private cloud computing environments can be divded into two types…
on premises private cloud
service provider-managed private cloud (i.e., virtual private cloud)
define hybrid cloud computing
a cloud computing environment is composed of both private and public clouds integrated through networking.
give an example of how hybrid cloud computing is used
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
define autonomic computing
ability of IT systems to manage themselves and adapt to change in the computing environment, business policies, and operating objectives
what is the goal of autonomic computing
create complex systems that run themselves, while keeping the system’s complexity invisible to the end user
autonomic computing address 4 key functions…
self-configuring
self-healing
self-optimizing
self-producing
the internt of things (IoT) is 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
define sensor and give examples
device that is capable of sensing something about its surroundings
pressure, temperature, humidity, pH level, motion, vibration, or level of light
give examples of IoT
home automation
wearable devices
smart cities
autonomous vehicles

busines benefits of IoT
reduced costs to achieve a competitive advantage
deepen the organization’s understanding of consumer preferences and behaviors
improve customer service and experience
improve workplace safety
types of IoT applications
connect and monitor
control and react
predict and adapt
transform and explore
connect and monitor degree of sensing? and degree of action?
individual devices each gather a small amout of data
enables manual monitoring using simple threshold-based exception alerting
control and react degree of sensing? and degree of action?
individual devices each gather a small amout of data
automatic monitoring combined with remote control with trend analysis and reporting
predict and adapt degree of sensing? and degree of action?
external data is used to augment sensor data
data used to perform predictive anaylsis and initate preemptive action
transform and explor degree of sensing? and degree of action?
sensor data combined with external data is used to provide new insights
new business models, products, and services are created
potential issues with IoT applications
many issues with the receipt and usability of sensor data
security is a very major issue
define smart city
Cities that make use of data from sensors combined with artificial intelligence to improve infrastructure and efficiently manage traffic lights, power plants, water supplies, networks, energy usage, and other resources.
virtualization tools
A set of tools that allow users to access their desktop operating system hosted in the cloud on a centralized server—meaning users can interact with files and applications as if they were stored on a local device.
