3.1 Flashcards
Responsibility Matric
outlines the division of responsibilities between the cloud service provider and the customer
Cloud Computing
delivering of computing services over the internet
Third Party Vendors
provides specialized services to enhance cloud solutions security, efficiency and functionality
Hybrid solutions
combine on prem, with cloud
Virtualization
emulates servers each with its own OS within a VM
Containerization
lightweight alternative encapsulating apps with their os environment they share the os
Type 1 Hypervisor
runs directly on hardware
Type 2 hypervisor
operates within a standard OS
Serverless
shifts server management away from developers
FaaS
developers write and deploy individual functions triggered by events
Microservices
breaking down large apps into small independent services
Air Gapping
physical separation of systems, disconnecting them from all networks one of the best security measures
Logical separation
establishes boundaries within a network to restrict access to certain areas
implemented by using firewalls VLANs
easier to implement then air gapping
SDN
software defined network
network management
provides centralized view of entire network
SDN Architecture
decouples network control and forwarding functions
Data plane
control plane
In traditional networking, both the control plane (deciding how data should be routed) and the data plane (actually forwarding the data) are tightly coupled within networking devices like switches and routers.
In SDN, these functions are decoupled, allowing centralized control of network behavior and policies through a software-based controller.
SDN Data Plane
responsible for handling data packets
makes decisions based on protocols like IP and ethernet concerned with sending and recieving data
Control Plane SDN
centralized decision maker
dictates traffic flow across whole network
SDN App Plane
host all network apps that interact with the SDN controller
IAC
automates provisioning and management through code
used in devlops
Idempotence
operation consistently produces the same results
Centralized Architecture
All computing functions managed from a single location
Decentralized
computing functions are distributed across multiple systems
IoT
internet of things
network of physical devices with sensors software and connectivity
Hub Control System
central component connecting IoT devices to
Smart Devices
everyday objects enhanced with computing and internet capabilities
Sensors
detect changes in environment and convert into data temperature, motion etc
ICS
Industrial Control System
used to monitor and control industrial processes found in industies like electrical water oil gas and data
DCS
distributed control system
used in control production
systems within a single location
a type of ics specifically used for industrial plants with a focus on centralized control
PLCs
programmable logic controllers
used to control specific processes such as assembly lines and facotries
PLC, or Programmable Logic Controller, is a specialized digital computer used in industrial automation and control systems to automate various electromechanical processes. PLCs are widely used in manufacturing plants, factories, and other industrial environments to monitor inputs, make decisions based on a program, and control outputs to automate processes.
SCADA systems
supervisory control and data acquisition systems
type of ICS designed for monitoring and controlling geographically dispersed industrail processes
common in electric power generation transmission and distribution systems
water treatment oil and gas
it is the central management interface for an ICS
Embedded systems
specialized computing components designed for dedicated functions within larger devices
RTOS
real time OS
flight navigation and medical equipment
