Cloud Native Drives Digital Transformation: From Containers to Serverless, Service Mesh, and Edge Computing

Speaker Yi Li, senior technical expert at Alibaba Cloud Container Platform, introduces the topic “The Turning Point Has Arrived: Cloud‑Native Leads Digital Transformation”. He outlines four key trends: embracing Serverless for ultra‑elastic, zero‑ops workloads; adopting Service Mesh to decouple service‑governance from applications; standardizing cloud‑native application management; and achieving compute without boundaries across cloud, edge, and IoT.

1. Cloud‑Native Basics

Cloud‑native computing combines best‑practice methodologies to build scalable, robust, loosely‑coupled applications on public or private clouds, leveraging containers, service mesh, and serverless paradigms.

Customers now focus on how to adopt cloud and maximize its value, treating cloud as an IT capability enhancer.

Containers introduced the cloud‑native era: Docker images decouple applications from runtime environments, and Kubernetes became the standard for distributed resource scheduling and orchestration.

Alibaba Cloud’s ACK (Alibaba Cloud Kubernetes) integrates enterprise services such as EDAS, Flink, EAS, and BaaS on top of Kubernetes.

2. From Containers to Serverless

Serverless Kubernetes (ASK) removes the need for users to manage nodes; all infrastructure is fully managed by Alibaba Cloud, enabling pay‑as‑you‑go consumption.

Key features: no reserved resources, zero‑maintenance nodes, on‑demand resource creation.

Example: an online‑education customer reduces compute cost to one‑third of traditional node‑based pricing.

Viking – Nodeless Architecture

Viking implements a “nodeless” design using Elastic Container Instance (ECI) and Virtual‑Kubelet, allowing Pods to run on virtual nodes without underlying VMs.

ECI provides native Pod support, sandbox isolation, and integrates with Alibaba DNS, SLB, and Ingress for full Service capabilities.

By snapshotting container images onto data‑disk snapshots, startup time can be reduced to under one second using Pangu 2.0 and ESSD I/O performance.

3. Extreme Elasticity

ACK uses cluster‑autoscaler for node‑level scaling and virtual‑node‑based ECI for pod‑level scaling, supporting spot instances and rapid scaling of thousands of nodes within minutes.

Application‑level scaling is achieved via HPA, VPA, and custom metrics adapters.

4. Security Sandbox Evolution

Traditional Docker RunC shares the host kernel, posing security risks. Alibaba Cloud introduced RunV, a lightweight‑virtualization sandbox with independent kernels, achieving ~90% of RunC performance.

Future plans include RunE, an SGX‑based trusted execution environment for confidential workloads.

5. From Microservices to Service Mesh

Microservice frameworks embed governance logic, leading to tight coupling. Service Mesh (e.g., Istio) externalizes governance to a sidecar, enabling language‑agnostic, independent evolution.

Alibaba and Ant Financial have deployed large‑scale Service Mesh in production, with plans for a managed offering.

6. Application Lifecycle Automation – OpenKruise

OpenKruise extends Kubernetes with controllers such as BroadcastJob, SidecarSet, and Advanced StatefulSet to simplify batch tasks, sidecar management, and in‑place updates.

7. Open Application Model (OAM)

OAM defines a standardized cloud‑native application model separating component definition, operational configuration, and infrastructure parameters, facilitating collaborative delivery.

8. Compute Without Boundaries – Cloud‑Edge Collaboration

With 5G and AI acceleration, workloads are extending from cloud to edge. ACK@Edge provides unified management of cloud ECS, edge ENS, and IoT devices, offering isolation, autonomous recovery, and self‑healing.

Use cases such as Youku’s “Jindou Cloud” demonstrate 50% cost savings and 75% latency reduction by deploying AI inference and real‑time processing at the edge.

Finally, Alibaba Cloud emphasizes giving back to the open‑source community, continuously contributing best practices from large‑scale production to projects like Kubernetes, Istio, and OpenKruise.
