Application Migration¶
Modernization¶
Enterprise Migration¶
- (2020) konveyor 🌟 [GO CONTENT] 🌟🌟🌟🌟 [ENTERPRISE-STABLE] [LEGACY] — An open-source application modernization platform that helps developers migrate legacy virtual machines, stateful services, and bare-metal workloads to Kubernetes. It provides discovery, analysis, and execution tools for large-scale container migrations.
Cloud-Native Migration¶
Application Modernization¶
Source-to-Image¶
- (2022) slideshare.net: Migrating Java JBoss EAP Applications to Kubernetes With' S2I 🌟🌟🌟 [LEGACY] — Presentation outlining migration strategies for porting legacy Java JBoss EAP applications into Red Hat OpenShift/Kubernetes using Source-to-Image (S2I). While S2I remains an enterprise staple in traditional OpenShift pipelines, the industry in 2026 has increasingly shifted toward Cloud Native Buildpacks.
Infrastructure¶
Control Plane¶
ETCD Administration¶
- (2025) github.com/gardener/etcd-backup-restore ⭐ 329 [GO CONTENT] [ADVANCED LEVEL] 🌟🌟🌟🌟 [ENTERPRISE-STABLE] — Developed under the Gardener project, this agent automates snapshot generation, compression, and synchronization of multi-node ETCD clusters. Continuously writes transactional delta logs to private S3 endpoints.
Data Protection¶
GitOps Synchronizers¶
- (2023) kube-backup: Kubernetes resource state sync to git ⭐ 493 [SHELL CONTENT] 🌟🌟🌟 [COMMUNITY-TOOL] — Automates Kubernetes resource state replication directly to target Git repositories. This pattern acts as an early architectural precursor to fully fledged declarative GitOps platforms, maintaining a point-in-time configuration ledger.
Kubernetes Backup Operators¶
- (2026) github.com/vmware-tanzu/velero ⭐ 10062 [GO CONTENT] 🌟🌟🌟🌟🌟 [DE FACTO STANDARD] — Velero is the standard open-source utility for safely backing up and restoring entire Kubernetes cluster structures and persistent volumes. Deeply integrates with both raw cloud APIs and file-level utilities like Kopia and Restic.
- (2025) k8up.io [GO CONTENT] 🌟🌟🌟🌟 [ENTERPRISE-STABLE] — K8up uses standard CRD objects to configure high-frequency Restic backups on selected persistent volumes. Offers integrated S3 exports, backup target management, and pruning policies.
- (2024) Stash ⭐ 1416 [GO CONTENT] [ADVANCED LEVEL] 🌟🌟🌟🌟 [ENTERPRISE-STABLE] — An advanced Kubernetes-native operator utilizing Restic underneath to back up stateful persistent volumes. Stash implements native CSI VolumeSnapshot integrations to handle application-consistent recovery processes with automated deduplication.
Workload Mobility¶
Migration Toolkits¶
- (2025) github.com/konveyor 🌟 [GO CONTENT] [ADVANCED LEVEL] 🌟🌟🌟🌟 [ENTERPRISE-STABLE] — An open-source modernization and migration suite designed to analyze, refactor, and migrate complex application workloads to Kubernetes across multiple physical and cloud ecosystems.
- (2024) github.com/konveyor/crane: Crane 2.0 🌟 ⭐ 54 [GO CONTENT] [ADVANCED LEVEL] 🌟🌟🌟🌟 [ENTERPRISE-STABLE] — Crane 2.0 provides continuous state synchronization, target resource modifications, and mock-run configurations to assist operators with real-time Kubernetes cluster replatforming campaigns.
