Here's a detailed summary of the video transcription in Markdown format:
Introduction
- The session introduces a new feature for Amazon EKS (Elastic Kubernetes Service) called EKS Hybrid Nodes.
- EKS Hybrid Nodes allow you to use your on-premises and edge infrastructure as capacity in EKS clusters.
- The speaker, Chris Splinter, is a Product Manager on the Kubernetes team at AWS, focusing on building EKS products that extend EKS beyond AWS environments.
- They also have Jonathan Ogden from Northwestern Mutual, who will share his team's experience with Hybrid Nodes.
Challenges with Running Kubernetes On-Premises
- Operational overhead in managing Kubernetes clusters, such as patching, keeping control planes up-to-date, and dealing with cluster certificate expiration.
- Limited experience with managing Kubernetes.
- Technology sprawl, with different tools and systems used for cloud and on-premises environments.
EKS Portfolio for On-Premises and Edge Use Cases
- EKS on Outpost: AWS-managed infrastructure that can be run in your data center or colocation facilities.
- EKS Anywhere (EKSa): AWS-supported Kubernetes management software that runs on infrastructure you manage.
- EKS Hybrid Nodes: Allows you to use your existing on-premises and edge infrastructure as nodes in EKS clusters.
EKS Hybrid Nodes
- Enables you to unify how you manage Kubernetes across both your cloud and on-premises environments.
- Can be used with any physical or virtual machines you manage.
- Uses the same AWS-managed EKS cluster features and tools as your cloud workloads.
- Integrated with other AWS services like SSM, IAM Roles Anywhere, Amazon Managed Prometheus, and CloudWatch.
Use Cases for EKS Hybrid Nodes
- Enterprise modernization: Customers who are running on VMs or self-managing Kubernetes on-premises.
- Machine learning: Leverage GPUs in on-premises environments within the same EKS cluster.
- Distributed edge use cases: Media streaming and manufacturing, taking advantage of the scale of Amazon EKS.
EKS Hybrid Nodes Architecture and Prerequisites
- The EKS control plane runs in the AWS region, while the worker nodes run on-premises.
- Requires private connectivity between the EKS VPC and your on-premises environment (e.g., AWS Direct Connect, VPN).
- Supports Ubuntu, Red Hat Enterprise Linux, and Amazon Linux 2023 (virtualized) as operating systems.
- Uses temporary IAM credentials for authentication, either via Systems Manager Hybrid Activations or IAM Roles Anywhere.
Networking and Configuration
- Remote node network and remote pod network configurations are set up during EKS cluster creation.
- Routing tables on both the VPC and on-premises sides need to be configured to route traffic between the two environments.
- Recommended network requirements: at least 100 Mbps bandwidth and less than 200 ms round-trip latency between the control plane and hybrid nodes.
Node ADM Command-Line Interface
- Simplifies the lifecycle management of hybrid nodes.
- Automates the process of bootstrapping hybrid nodes to EKS clusters.
- Can be integrated into your operating system build pipelines.
- Supports both SSM Hybrid Activations and IAM Roles Anywhere for temporary credential provisioning.
Features and Best Practices
- Hybrid Nodes is available in all AWS regions except GovCloud and China.
- Supports the same EKS Kubernetes versions, cluster management interfaces, and add-ons as standard EKS.
- Best practices include automating node bootstrapping, using the closest AWS region, coordinating with networking/security teams, and leveraging AWS integrations.
Northwestern Mutual's Experience
- Began their Kubernetes journey 9 years ago, running Kubernetes the "hard way" on-premises.
- Migrated to Amazon EKS in the cloud, but needed an on-premises Kubernetes solution as well.
- EKS Hybrid Nodes allowed them to unify their Kubernetes management across cloud and on-premises environments.
- Experienced some networking and security configuration challenges, but were able to test and validate the solution.
- EKS Hybrid Nodes helped them increase stability, security, standardization, simplification, cost control, and staff experience.
Conclusion
- Additional EKS-related sessions and resources are provided for further learning.
