Library of Congress Storage Architecture

In 2026 is there demand for 7X more manufactured storage annually and is there sufficient value for this storage to spend $122B more annually (2.4X) for this storage? Unlike HDD, tape magnetic physics is not the limiting issues since tape bit cells are 60X larger than HDD bit cells … The projected tape areal density in 2025 (90 Gbit/in2) is 13x smaller than today’s HDD areal density and has already been demonstrated in laboratory environments.

IBM is the last of the hardware manufacturers: IBM is the only builder of LTO8 IBM is the only vendor left with enterprise class tape drives If you only have one manufacturer how do you mitigate risk? These cloud archival solutions all use tape: Amazon AWS Glacier and Glacier Deep ($1/TB/month) Azure General Purpose v2 storage Archive ($2/TB/month)

Google GCP Coldline($7/TB/month) If it’s all the same tape, how do we mitigate risk?

Kubernetes Failure Stories

I started to compile a list of public failure/horror stories related to Kubernetes. It should make it easier for people tasked with operations to find outage reports to learn from. Since we started with Kubernetes at Zalando in 2016, we collected many internal postmortems.

Observability at Scale: Building Uber’s Alerting Ecosystem

Uber’s software architectures consists of thousands of microservices that empower teams to iterate quickly and support our company’s global growth. These microservices support a variety of solutions, such as mobile applications, internal and infrastructure services, and products along with complex configurations that affect these products at city and sub-city levels. To maintain our growth and architecture, Uber’s Observability team built a robust, scalable metrics and alerting pipeline responsible for detecting, mitigating, and notifying engineers of issues with their services as soon as they occur.
