FAQ

1. How long does a typical migration from Kubernetes take? Migration timeframes vary significantly based on application complexity and environment size. Small deployments might complete in 2-4 weeks, while enterprise-scale migrations typically require 3-6 months for a full transition.
2. Can I maintain existing container configurations when switching to alternatives? While basic container configurations can often be migrated, platform-specific features may need reconfiguration. It's recommended to maintain parallel environments during transition and gradually migrate workloads.
3. What's the most cost-effective Kubernetes alternative? Open-source solutions like K3s and Docker Swarm offer the lowest direct costs but require internal expertise. For commercial solutions, cloud provider options like ECS and ACI provide good value with consumption-based pricing models.
4. How do cloud-native alternatives compare to traditional container orchestration tools? Cloud-native solutions like ECS and Cloud Run typically offer better scalability and integrated services but may lead to vendor lock-in. Traditional tools like Docker Swarm provide more flexibility but require more manual management.
5. Is it possible to run multiple container orchestration solutions simultaneously? Many organizations maintain multiple orchestration tools during migration periods or for different use cases. However, this approach increases operational complexity and costs, so it's generally recommended to consolidate onto a single platform where possible.
