In the ever-evolving world of cloud computing, businesses are constantly seeking ways to enhance their resilience and ensure seamless operations, even in the face of unexpected challenges. Alibaba Cloud’s Distributed Cloud Container Platform, ACK One, offers a comprehensive solution to this pressing need, enabling the quick and efficient setup of a hybrid cloud disaster recovery system.
🗺️ Navigating the Hybrid Cloud Landscape
For businesses currently running Kubernetes clusters in their on-premises Internet Data Centers (IDCs) and seeking to leverage cloud computing for high-availability redundancy, ACK One provides a centralized platform to manage traffic, applications, and clusters across multiple environments.
This article will guide you through the process of using ACK One to swiftly construct a robust hybrid cloud disaster recovery system, empowering your business to withstand unexpected disruptions and maintain uninterrupted operations.
📋 Key Steps to Building a Hybrid Cloud Zone-Disaster Recovery System
- Leverage ACK One Registered Clusters: Manage Kubernetes clusters deployed on IDC or third-party clouds by registering them with ACK One.
- Interconnect On-premises and Cloud Networks: Establish a secure connection between your on-premises network and the Alibaba Cloud Virtual Private Cloud (VPC) using an Express Connect circuit.
- Create an ACK One Fleet: Centrally manage your clusters by associating them with an ACK One Fleet.
- Utilize ACK One GitOps (Optional): Distribute your applications to multiple clusters using the GitOps capabilities of ACK One.
- Employ ACK One Multi-cluster Gateways: Manage the north-south traffic across your hybrid cloud environment, ensuring seamless zone-disaster recovery.
🚀 Unleash the Power of ACK One
ACK One is an enterprise-level, cloud-native platform provided by Alibaba Cloud, designed to tackle hybrid cloud, multi-cluster, distributed computing, and disaster recovery scenarios. It enables the connection and management of Kubernetes clusters across various regions and infrastructures, while offering consistent management and community-compatible APIs for computing, networking, storage, security, monitoring, logs, jobs, applications, and traffic.
🔗 ACK One Registered Clusters
The ACK One Registered Clusters feature allows you to seamlessly connect your on-premises Kubernetes clusters to the Alibaba Cloud Container Service management platform, facilitating the quick setup of hybrid cloud environments.
🌐 ACK One Fleet
The ACK One Fleet serves as a centralized portal for managing multi-cluster environments, providing developers with capabilities such as multi-cluster GitOps application distribution, traffic management, and centralized operations and maintenance (O&M).
🚦 ACK One Multi-cluster Gateways
The ACK One Multi-cluster Gateways are cloud-native gateways that manage Layer 7 north-south traffic in multi-cloud and multi-cluster environments. These gateways leverage Ingress APIs to define traffic routing rules, supporting advanced capabilities like HTTP routing, traffic splitting, health-based automatic smooth disaster recovery, traffic mirroring, and load balancing based on the number of replicas.
💻 ACK One GitOps (Optional)
The ACK One GitOps feature manages ArgoCD within the Fleet instance, integrating capabilities like multiple clusters in ACK One and Alibaba Cloud RAM SSO to implement a simple and secure multi-cluster GitOps continuous delivery.
🏗️ Architecting the Hybrid Cloud Zone-Disaster Recovery System
To build a robust hybrid cloud zone-disaster recovery system, we’ll leverage the power of ACK One Registered Clusters, Multi-cluster Fleets (with optional GitOps), and Multi-cluster Gateways.
- All Alibaba Cloud resources will be housed in a single VPC (VPC 1 in the diagram).
- You can register Kubernetes clusters deployed on IDC or third-party clouds to Alibaba Cloud using the Registered Clusters feature, and then connect the IDC and VPC network using an Express Connect circuit.
- Associate the ACK clusters and Registered Clusters with the ACK One Fleet instance within the same VPC (VPC 1), and distribute applications across these clusters using ACK One GitOps (optional).
- In the ACK One Fleet, create MSE gateways through MseIngressConfig and add clusters to the gateways. Then, configure traffic routing rules using Ingress to manage the north-south traffic, including the implementation of zone-disaster recovery.
Remember, this article focuses on the highly available, multi-cluster deployment of applications and business traffic, without delving into the specifics of databases and middleware. For more information on those aspects, refer to the Alibaba Cloud database and middleware documentation.
🛠️ Building the Hybrid Cloud Zone-Disaster Recovery System
Let’s get started with the step-by-step process of constructing your hybrid cloud zone-disaster recovery system:
- Use Registered Clusters to Manage Kubernetes Clusters Deployed on IDC or Third-party Clouds
- Interconnect the On-premises Network with the VPC
- Create a Fleet and Associate Clusters
- Utilize GitOps to Distribute the Application to Multiple Clusters (Optional)
- Leverage Multi-cluster Gateways to Manage Multi-cluster Traffic
For detailed instructions on each step, please refer to the comprehensive documentation provided by Alibaba Cloud.
🏆 Conclusion
ACK One empowers businesses with a comprehensive multi-cluster management solution, enabling seamless application management from cluster access to distribution and traffic control. In hybrid cloud scenarios, Registered Clusters facilitate the integration of on-premises Kubernetes clusters, allowing for the efficient scaling of cloud computing resources (such as ECI) to quickly address fluctuations in service demand.
The GitOps capabilities of ACK One simplify the management of cloud and on-premises cluster applications, enabling the construction of automated CI/CD pipelines and streamlining application upgrades and operations. Furthermore, the Multi-cluster Gateways offer powerful traffic management functionalities, allowing for centralized control of north-south traffic across multiple clusters, reducing architectural complexity, and enhancing overall traffic management efficiency.
Embrace the future of hybrid cloud disaster recovery with ACK One and ensure the resilience and continuity of your business operations, even in the face of unexpected challenges.
