Kubernetes vs Temporal

Kubernetes is an open-source system for automating deployment, scaling, and management of containerized applications. It supports stateless, stateful, and data-processing workloads, and can run locally, in a cloud, or in a datacenter; users can also choose a managed service rather than operate a cluster themselves. It coordinates gradual updates while monitoring application health and can roll back a change if something goes wrong. Pods receive IP addresses and groups of Pods can share a DNS name, with load balancing across them. Kubernetes can mount storage from local, public-cloud, or network systems such as iSCSI or NFS. Secrets and configuration can be updated without rebuilding images. Scaling can be manual or automatic based on CPU use. Security mechanisms include Secrets, Pod security standards, RuntimeClasses, network policies, admission controllers, and audit logging. Kubernetes is free, with a listed plan price of free. It does not include application-level services such as databases, message buses, caches, or cluster storage systems.

Temporal is a workflow platform for applications that need work to recover after crashes, network failures, or infrastructure outages. Workflows preserve state at each step and resume from that point. Failure-handling tools include automatic retries with backoff, timeout classes, heartbeating, and Saga compensation. Durable timers can wait for months; cron schedules support backfill, and workflows can use Continue-As-New. Signals, Queries, Updates, and Workflow Streams let users read or change workflows while they run. Teams can self-host the open-source Temporal Service or use managed Temporal Cloud. SDKs are listed for Go, Java, Python, TypeScript,.NET, PHP, Ruby, and Rust, alongside integrations for several AI tools. Temporal Cloud keeps application code and data in customer-controlled infrastructure, sending encrypted orchestration data to the service; it uses AES 256 encryption at rest and TLS in transit. The cloud service is SOC 2 Type II certified and compliant with GDPR and HIPAA. Pay-As-You-Go has no base monthly fee and includes $150 in credits for 90 days; Business costs $500 a month or 10% of usage, whichever is greater.
