Containerization & Orchestration Glossary

From Docker to Kubernetes to Terraform, your passport to the containerized world of modern deployment.

NUMA-aware Scheduling

Kubernetes feature considering Non-Uniform Memory Access topology for optimal pod placement.

Namespace

Kubernetes abstraction for creating multiple virtual clusters within a physical cluster, providing a scope for names and resources.

Namespaces

Kubernetes feature for partitioning clusters into virtual sub-clusters, enabling resource isolation and access control.

Network Address Translation (NAT)

Process of modifying network address information in packet headers for routing in container networks.

Network Function Virtualization (NFV)

Concept of replacing dedicated network appliances with virtualized functions, often containerized.

Network Microsegmentation

Security technique dividing networks into isolated zones, enhancing container and microservices security.

Network Policies

Kubernetes resources specifying how groups of pods are allowed to communicate with each other and other network endpoints.

Network Policy

Specification of how groups of pods are allowed to communicate with each other and other network endpoints.

Network Policy Logging

Feature enabling logging of allowed and denied network connections based on Kubernetes Network Policies.

Network Segmentation

Practice of dividing a network into smaller segments or subnets, improving security and performance in container environments.

Network Service Mesh (NSM)

Cloud-native solution providing layer 2/3 network services to Kubernetes workloads, enhancing networking capabilities.

NetworkPolicy

Kubernetes resource defining rules for pod-to-pod and pod-to-external communication, implementing network segmentation.

NeuVector for Container Firewall

Security platform providing real-time container firewall, vulnerability management, and compliance for Kubernetes.

New Relic Container Monitoring

Observability platform offering performance monitoring and analytics for containerized applications and infrastructure.

Node

Basic unit of a distributed application in many systems, often referring to individual machines or processes.

Node Affinity

Kubernetes feature allowing pods to be scheduled on nodes with specific characteristics based on labels.

Node Authorization

Kubernetes authorization mode controlling kubelet access to the API server, enhancing cluster security.

Node Auto-provisioning

Feature automatically adjusting the number of nodes in a Kubernetes cluster based on workload demands.

Node Exporter

Prometheus exporter for hardware and OS metrics exposed by *NIX kernels, used for node-level monitoring in Kubernetes.

Node Feature Discovery

Kubernetes add-on detecting hardware features and system configuration, facilitating hardware-aware scheduling.

Node Name

Unique identifier for a node in a Kubernetes cluster, used in various operations and configurations.

Node Pressure Eviction

Process of removing pods from a node when it experiences resource pressure, ensuring stability.

Node Problem Detector

Kubernetes add-on monitoring and reporting node health issues, enhancing cluster reliability.

Node Restriction Admission Plugin

Kubernetes plugin limiting node and pod modifications to increase security and prevent privilege escalation.

Node Selector

Kubernetes feature for constraining pods to nodes with specific labels, enabling basic scheduling control.
