Choosing Kubernetes Workload Types#

Kubernetes provides several workload controllers, each designed for a specific class of application behavior. Choosing the wrong one leads to data loss, unnecessary complexity, or workloads that fight the platform instead of leveraging it. This guide walks through the decision criteria and tradeoffs for each type.

The Workload Types at a Glance#

Workload Type	Lifecycle	Pod Identity	Scaling Model	Storage Model	Typical Use
Deployment	Long-running	Interchangeable	Horizontal replicas	Shared or none	Web servers, APIs, stateless microservices
StatefulSet	Long-running	Stable, ordered	Ordered horizontal	Per-pod persistent	Databases, message queues, distributed consensus
DaemonSet	Long-running	One per node	Tied to node count	Node-local	Log collectors, monitoring agents, network plugins
Job	Run to completion	Disposable	Parallel completions	Ephemeral	Batch processing, migrations, one-time tasks
CronJob	Scheduled	Disposable	Per-schedule run	Ephemeral	Periodic backups, cleanup, scheduled reports
ReplicaSet	Long-running	Interchangeable	Horizontal replicas	Shared or none	Almost never used directly

Decision Criteria#

The choice comes down to four questions:

DaemonSets: Node-Level Workloads, System Agents, and Update Strategies

DaemonSets#

A DaemonSet ensures that a copy of a pod runs on every node in the cluster – or on a selected subset of nodes. When a new node joins the cluster, the DaemonSet controller automatically schedules a pod on it. When a node is removed, the pod is garbage collected.

This is the right abstraction for infrastructure that needs to run everywhere: log collectors, monitoring agents, network plugins, storage drivers, and security tooling.
