AWS re:Invent 2023 - Accelerate your Kubernetes journey with Amazon EKS (CON206)

Summary

• Amazon EKS addresses major customer concerns with Kubernetes in production, such as managing the control plane, scaling, and upgrades.
• EKS provides production-grade Kubernetes with pre-built options for logging, networking, and ingress, and supports battle-tested Kubernetes versions.
• Customers move to containers for speed, security, scalability, and cost-effectiveness, and EKS aligns Kubernetes' agility with enterprise processes.
• EKS clusters consist of a managed, resilient control plane and a data plane with various options for node management.
• EKS integrates IAM for user authentication and is introducing IAM cluster access management for easier control.
• EKS has reduced control plane upgrade times and is working on simplifying data plane and add-ons upgrades.
• Extended support for EKS is now available, extending the Kubernetes version support period from 14 to 26 months.
• Data plane options include self-managed EC2 instances, EKS-managed node groups, Carpenter, and AWS Fargate.
• EKS VPC CNI supports network policies using eBPF for efficient packet filtering.
• EKS integrates with AWS services for security, analytics, and threat detection, such as KMS, EMR, and GuardDuty.
• EKS offers cost optimization tools like the EKS-optimized Kubecost bundle and integrates with AWS Marketplace for third-party software.
• EKS can be deployed in various environments, including on-premises, to meet different needs.
• Pratik Gogia shared best practices based on managing numerous Kubernetes clusters, emphasizing the importance of pod and node autoscaling, monitoring, and using tools like CloudWatch and the CNI metrics helper.
• The session concluded with the announcement of the new digital EKS learning badge and its learning path.

Insights

• EKS simplifies Kubernetes management by automating complex tasks like upgrades and scaling, which are traditionally pain points for Kubernetes users.
• The integration of IAM with Kubernetes through EKS enhances security and simplifies user management, which is a significant improvement over native Kubernetes user management.
• EKS's extended support feature is a response to enterprise needs for longer support cycles due to various business and compliance requirements.
• The introduction of Carpenter and AWS Fargate as data plane options shows AWS's commitment to providing solutions that cater to different operational models and cost optimization needs.
• The built-in support for network policies in EKS VPC CNI using eBPF is a notable advancement, as it eliminates the need for third-party CNIs and improves performance.
• AWS's focus on integrating EKS with other AWS services like EMR, GuardDuty, and AWS Marketplace demonstrates the company's strategy to offer a cohesive and secure cloud ecosystem.
• The emphasis on cost monitoring and optimization reflects a growing industry trend where organizations are seeking to gain better visibility and control over their Kubernetes-related expenses.
• The best practices shared by Pratik Gogia highlight the importance of autoscaling, monitoring, and proper configuration to ensure the smooth operation of Kubernetes clusters in production.
• The launch of the digital EKS learning badge indicates AWS's efforts to formalize and recognize Kubernetes expertise, which could help professionals demonstrate their skills in a rapidly evolving cloud landscape.
