In this post, you'll learn how to: (1) enable Container Network Observability in your Amazon EKS cluster, (2) identify and reduce inter-AZ traffic using traffic distribution control, (3) identify and reduce NAT gateway…

  • Why it's relevant: matches terms: aws, cloud; fits IT category
  • Summary:
    • Track inter-AZ and NAT gateway traffic with EKS Container Network Observability Teams running microservices on Amazon Elastic Kubernetes Service (Amazon EKS) struggle to identify which services drive their data transfer costs.
    • As clusters grow and service-to-service communication increases, inter-AZ traffic (data transfer between zones within the same region) and NAT gateway processing charges add up fast.
    • Without pod-level visibility into these network flows, it’s difficult to pinpoint which workloads contribute most.

    • Timeless principles that separate products people use from products people love.
    • In Three Dimensions of Loveable Products, I argued that a loveable product needs three qualities: utility, usability, and craft.
    • Utility and usability are well understood.

What the PNR locator on your boarding pass actually contains, and why fare calculations are written in a currency that does not exist.

  • Why it's relevant: fits Design category
  • Summary:
    • Six Characters Part 2 of 6 in the Iron Core series: the 60-year-old infrastructure that flies 4.5 billion people a year.
    • My Air India e-ticket has a line on it that looks like a typographical error: It is not a typographical error.
    • It is a fare calculation: expressed in a notation system designed in the 1970s, referencing a currency that does not exist (NUC), and priced to a city code (LON) rather than an airport.

Connections

  • Infrastructure Evolution: Modern cloud monitoring (AWS EKS observability) and legacy aviation systems both grapple with managing complex, distributed architectures across time scales, suggesting that observability tools must adapt to both rapidly evolving microservices and decades-old infrastructure.
  • Design Philosophy: The principles of product craft (utility, usability, craft) and modular agent design reflect a shared emphasis on intentional architecture, indicating that whether creating user-facing products or AI systems, thoughtful decomposition of functionality leads to more maintainable solutions.
  • System Longevity: The contrast between ephemeral cloud services and 60-year-old aviation infrastructure highlights a tension between rapid technological obsolescence and enduring system design, suggesting that successful architectures must balance innovation with sustainability.
