# Hybrid cloud orchestration: Modernizing on-premises infrastructure management with AWS

## Summary

Managing distributed on-premises infrastructure across hundreds of sites creates inconsistency, manual lifecycle bottlenecks, fragmented visibility, and scalability problems, especially when hardware, operating system, Kubernetes, and application operations span thousands of servers. The proposed design centralizes orchestration in AWS while keeping execution on site, using hybrid connectivity, AWS Lambda, AWS Step Functions, Amazon EventBridge, DynamoDB, AWS Systems Manager, and supporting services. Redfish APIs provide vendor-agnostic bare-metal control for BIOS, firmware, power, and health operations, while EKS Anywhere deploys and operates management and workload clusters on local hardware; orders and inventory records track workflows and resource relationships. DynamoDB Streams also automate DNS, certificates, AWS access, and storage integrations, while centralized observability aggregates server, cluster, and application signals; the post presents architectural patterns and defers detailed implementation workflows and templates to later parts.

## Context

Distributed on-premises environments with geographically dispersed data centers and thousands of servers face inconsistent procedures, manual lifecycle operations, fragmented visibility, and coordination limits at enterprise scale. Some environments must keep the Kubernetes control plane on premises because of data sovereignty, regulatory or policy requirements, or disconnected, disrupted, intermittent, or limited connectivity to AWS.

## Approach / What changed

The architecture uses a centralized AWS orchestration engine, distributed EKS Anywhere infrastructure, and hybrid connectivity. AWS Lambda, Step Functions, EventBridge, DynamoDB, Systems Manager, CodeBuild, and Batch coordinate event-driven workflows, while Redfish standardizes bare-metal operations. DynamoDB-based inventory tracks sites, servers, clusters, orders, and configurations, and streams automate integrations for DNS, certificates, AWS access, storage, and observability.

## Takeaways

- Orders give infrastructure operations unique identifiers, trigger EventBridge-routed Step Functions workflows, and expose progress through state changes recorded in the inventory system.
- Amazon EKS Anywhere keeps cluster operations on local hardware and supports a bare-metal provider; Amazon EKS Hybrid Nodes is recommended when workloads can use a managed EKS control plane with reliable AWS connectivity.
- AWS IAM Roles Anywhere supplies short-lived credentials to on-premises workloads through trusted certificates, avoiding long-lived AWS keys at individual sites.
