What the New CNCF Application Delivery SIG Means for Cloud‑Native Developers

Background and SIG Formation

The Cloud Native Computing Foundation (CNCF) announced the creation of the Application Delivery Special Interest Group (App Delivery SIG). The inaugural co‑chairs are Alibaba Cloud senior technologist Zhang Lei, Dynatrace’s chief technology and strategy officer Alois Reitbauer, and VMware expert Bryan Liles. CNCF SIGs serve as a core mechanism for coordinating technology areas, connecting end‑users, open‑source projects, and the CNCF Technical Oversight Committee (TOC).

Purpose and Responsibilities

The App Delivery SIG is the first CNCF group focused explicitly on the "application" layer. It inherits the former Serverless Working Group and aims to clarify and solve critical challenges across the application delivery lifecycle, optimize cloud‑native application architecture, and bridge gaps between open‑source practice and theory.

Mission and Vision

According to the SIG’s TOC liaison, the group will work to establish a "cloud‑native application management and standard delivery system" and promote a layered model that separates application definition, deployment & delivery, and instance management. This model is intended to standardize, modularize, and assign clear responsibilities to each layer, addressing current deficiencies in the cloud‑native ecosystem.

For example, a blue‑green deployment concerns the deployment & delivery layer, while a Kubernetes Deployment or Operator provides the underlying instance‑management capabilities; the two layers interact without being tightly coupled.

Planned Deliverables

Abstract and refine best practices, reference architectures, and project examples for each layer of the model.

Publish a "CNCF Cloud‑Native Application Architecture Whitepaper" summarizing these findings.

Produce a "Cloud Native App Delivery Landscape" guide to help users select and architect solutions.

Continuously identify and incubate open‑source projects that align with the layered approach.

Alibaba’s Cloud‑Native Experience

Alibaba Cloud has been adopting cloud‑native technologies since 2011, evolving from container adoption to Kubernetes, serverless, and service‑mesh. The company emphasizes automated, self‑healing application management, enhanced observability, and tight integration between Kubernetes and higher‑level application platforms.

Alibaba stresses that application delivery is not synonymous with CI/CD; while CI/CD focuses on developer productivity, cloud‑native application delivery builds the foundational infrastructure for managing applications at scale. Advanced delivery techniques, such as those provided by the OpenKruise project (originating from Alibaba), enable in‑place upgrades and support large‑scale, stateful deployments like those required for China’s "Double‑Eleven" shopping festival.

Future Outlook

With the SIG’s establishment, Alibaba plans to deepen collaboration with CNCF, pilot the "cloud‑native application management and standard delivery" framework in both internet and cloud‑product scenarios, and contribute its open‑source innovations back to the community.

The formation of the App Delivery SIG marks a milestone in the cloud‑native ecosystem, shifting focus from pure infrastructure to the application layer and establishing new standards, models, and best practices for the next generation of cloud‑native software.
