Containerization & Orchestration Glossary

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

Layered File System

Storage mechanism used by container runtimes, allowing efficient storage and quick updates of container images.

Leader Election Pattern

Design pattern ensuring only one instance of a distributed application component is active at a time.

Leader Election in Operators

Process where multiple instances of an operator elect a leader to prevent conflicts in resource management.

Least Privilege Principle

Security concept of giving a user or process only the minimum levels of access necessary to perform its function.

Lens IDE for Kubernetes

User-friendly, open-source IDE for managing Kubernetes clusters, providing a unified interface for multiple clusters.

Lightstep

Observability platform providing insights into the behavior of highly distributed software systems and microservices.

Limit Ranges

Kubernetes policy for constraining resource allocations (CPU and memory) for pods or containers in a namespace.

LimitRange

Kubernetes object defining the min, max, and default compute resources for pods and containers in a namespace.

Linkerd

Lightweight service mesh for Kubernetes, providing observability, reliability, and security for microservices.

Linkerd Data Plane

Component of Linkerd responsible for proxying traffic between services, implementing service mesh functionality.

Linkerd Service Profiles

Linkerd resource providing service-specific traffic metrics and control, enhancing observability and management.

Linkerd's Ultra-lightweight Proxy

High-performance, minimal-footprint proxy used in Linkerd's data plane for efficient service mesh operations.

Linux Security Modules (LSM)

Framework allowing various security models to be plugged into the Linux kernel, enhancing container isolation.

Load Balancer Integration

Process of connecting external load balancers with Kubernetes services for distributing incoming traffic.

Load Balancing Algorithms

Methods used by load balancers to distribute traffic across multiple container instances or pods.

LoadBalancer

Kubernetes service type that provisions an external load balancer in cloud environments for routing external traffic to services.

Local Persistent Volumes

Kubernetes volume type for locally attached storage, providing high-performance storage options for stateful workloads.

Locality Load Balancing

Technique for routing traffic to geographically or topologically closer endpoints in distributed container deployments.

Log Aggregation Patterns

Techniques for collecting, processing, and storing logs from distributed containerized applications for centralized analysis.

Logging Architecture

Design of systems for capturing, storing, and analyzing logs from containers and orchestration platforms.

Loki

Horizontally-scalable, multi-tenant log aggregation system designed for use with Prometheus and Kubernetes.

Longhorn

Cloud-native distributed block storage system for Kubernetes, providing persistent storage for stateful workloads.

Longhorn Distributed Block Storage

Implementation of Longhorn for providing resilient, replicated block storage in Kubernetes clusters.

Low-Level vs High-Level Runtimes

Comparison of container runtimes operating at different abstraction levels, balancing performance and features.

Materialized View Pattern

Technique for precomputing and storing query results, improving performance in microservices architectures.
