k8or on CP + Local Products: A Deep Dive
The third k8or deployment option, "k8or on CP + Local Products", bridges the gap between on-premises control and cloud provider scalability. While leveraging the managed Kubernetes products of a cloud provider (e.g., AWS EKS, GCP GKE), this configuration mirrors option 1 by deploying all essential products like database, storage, and authentication/authorization within k8or.
Key Characteristics:
-
Built on BLOCK Framework:
Is a powerful framework for designing and building efficient and well-structured web and mobile applications.
-
Custom Images:
k8or is built with images k8orized at OS, package, application, and microservice levels.
-
Managed Kubernetes Product Utilization:
You leverage the cloud provider's managed Kubernetes product, offloading the burden of managing the control plane and worker nodes. This simplifies initial setup and ongoing maintenance.
-
Local Product Deployment:
Similar to option 1, all necessary products are deployed and managed within k8or, utilizing containerized solutions or cloud provider offerings compatible with Kubernetes.
-
Cloud-Enabled Scalability:
Scaling k8or and products becomes easier by leveraging the cloud provider's scaling capabilities, offering on-demand adjustments and access to a wider range of product options.
Technical Implementation:
-
Cloud Provider Selection:
Choose the cloud provider based on your requirements, considering factors like supported containerized options, available managed Kubernetes products, and regional availability.
-
Resource Provisioning and Deployment:
Utilize the cloud provider's tools and Kubernetes manifests to deploy and configure containerized databases, storage solutions, and authentication/authorization products within k8or.
-
k8or on Cloud Provider with Local Products:
Picture a managed Kubernetes product on the cloud, like a trusty squire handling the heavy lifting. You still deploy your own products within k8or, maintaining control, but with the added convenience of managed products.
-
Network Security and Access Control:
Implement network policies and access controls to restrict communication between pods and external networks, ensuring secure access to internal products.
-
IAM Integration:
Leverage the cloud provider's IAM functionalities to control access to products from outside k8or. Utilize service accounts and Kubernetes RBAC for granular access control within k8or.
-
Monitoring and Logging:
Extend your monitoring and logging infrastructure to encompass k8or products and cloud provider metrics. Utilize the cloud provider's native tools or integrate them with your existing stack for holistic visibility.
Benefits and Considerations:
-
Simplified Management:
Utilizing a managed Kubernetes product removes the complexity of managing the control plane and worker nodes, reducing operational overhead.
-
Enhanced Scalability and Flexibility:
Cloud provider offerings enable easier scaling of both k8or and internal products, adapting to changing demands and leveraging a wider range of options.
-
Security and Control:
You maintain control over internal resources and network access within k8or, offering additional security and isolation compared to fully external cloud-based deployments.
-
Potential Vendor Lock-in:
Reliance on specific cloud provider products can introduce vendor lock-in, potentially making migration to other platforms challenging in the future.
-
Increased Complexity:
Integrating internal products and managing their configurations adds complexity compared to solely utilizing cloud provider-managed products.
The "k8or on CP + Local Products" offers a powerful blend of cloud provider convenience and on-premises control. This hybrid approach simplifies k8or management while giving you greater control over your application's products and security posture. While carefully considering potential lock-in and increased complexity, this option can be ideal for organizations seeking scalability and flexibility within a secure and controlled k8or environment.
