KubeMeet 2024: KubeVela, OAM & OpenKruise Redefine Cloud‑Native App Delivery

KubeVela‑Based Application Delivery at Alibaba

Alibaba built a standardized application delivery platform on KubeVela 1.0 to address fragmentation caused by diverse workload types, multi‑cluster environments, gray‑release strategies, and heterogeneous logging/monitoring systems. The platform abstracts these complexities and integrates with external tools such as Terraform and Crossplane, as well as cloud resource credentials (e.g., AK/SK, database connection strings). It provides a unified management layer that enables developers to define delivery pipelines once and apply them across public‑cloud, private‑cloud, and hybrid deployments.

AIOS Application Management with OAM (Fourth Paradigm)

Fourth Paradigm created an AI‑focused platform called AIOS on top of the OAM Kubernetes runtime . By extending OAM’s Workload and Trait definitions, AIOS allows ecosystem partners to integrate AI services with minimal code changes. The platform supports DAG‑based computation for internal modeling workloads, offering flexible, reliable, and scalable PaaS capabilities for AI applications.

OpenKruise Enables Container‑Granular Operations in Kubernetes

OpenKruise adds fine‑grained, container‑level controls to vanilla Kubernetes without invasive changes. Key capabilities include:

In‑place upgrades of individual containers within a Pod.

Sidecar injection, management, and independent upgrades.

Container‑level restarts and lifecycle management.

These features overcome the default pod‑level scaling model and enable more precise operational workflows.

OpenKruise Adoption at Ctrip

Ctrip integrated OpenKruise into its PaaS platform to achieve native Kubernetes releases, high‑availability control planes, multi‑cluster federation, and management of multi‑stateful workloads. The rollout capabilities of OpenKruise enabled Ctrip to implement cloud‑native deployment pipelines, address high‑availability requirements, and plan future enhancements for workload resilience and scaling.
