Containerization & Orchestration Glossary

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

Thanos for Long-Term Storage

Use of Thanos to provide durable storage and global query capability for Prometheus metrics.

Throttling Pattern

Technique for limiting the rate at which a containerized service processes requests to prevent overload.

Tilt for Microservices Development

Development environment as code for teams building Kubernetes microservices, streamlining local development.

Timeout Configuration

Settings controlling the maximum duration for various operations in containerized applications and infrastructure.

Tolerations

Kubernetes pod specifications that allow (but do not require) pods to be scheduled on nodes with matching taints.

Topology Manager

Kubernetes feature coordinating resource allocation decisions to provide topology-aligned resource allocations.

Traffic Mirroring

Technique of duplicating live traffic to a separate service instance for testing or debugging purposes.

Traffic Shifting

Gradual redirection of traffic from one version of a service to another, often used in canary deployments.

Traffic Splitting

Distribution of incoming requests across multiple versions of a service, enabling advanced deployment strategies.

Trivy for Vulnerability Scanning

Open-source security scanner for containers and other artifacts, finding vulnerabilities and misconfigurations.

Twelve-Factor App Methodology

Set of best practices for building software-as-a-service apps that can be easily deployed to the cloud.

Twistlock

Container security platform providing vulnerability management, compliance, and runtime protection (now part of Prisma Cloud).

Twistlock (now Prisma Cloud)

Comprehensive cloud-native security platform for containers, serverless, and cloud environments.

Underlay Networks

Physical network infrastructure upon which overlay networks for container communication are built.

Unikernels as Container Alternatives

Specialized, single-purpose machine images offering potential advantages in size and security over containers.

Union File System

Filesystem service for Linux allowing files and directories of separate filesystems to be overlaid, forming a single coherent filesystem.

User Impersonation

Kubernetes feature allowing a user to act as another user, useful for debugging and testing access controls.

User Namespaces

Linux kernel feature providing per-process isolated instances of user and group ID number spaces.

VXLAN

Network virtualization technology used in container networking for creating overlay networks.

VXLAN Overlay Networks

Virtual networks using VXLAN encapsulation to enable container communication across hosts.

Valet Key Pattern for Secure Resource Access

Design pattern for providing clients with restricted direct access to a specific resource or service.

Validating Webhooks

Admission controller webhooks in Kubernetes that validate resource requests without modifying them.

Validation Webhooks

Kubernetes admission control mechanism for validating API requests against custom logic before persistence.

Velero for Backup and Restore

Open-source tool for backing up and restoring Kubernetes cluster resources and persistent volumes.

Version Skew Policy

Guidelines defining supported version differences between Kubernetes components to ensure compatibility.
