Announcing vector search for Amazon ElastiCache (1 minute read) Amazon has announced the general availability of vector search for ElastiCache, enabling customers to index, search, and update billions of vector embeddings from major AI providers with microsecond latency and up to 99% recall. The feature supports use cases like semantic caching for LLMs, RAG-based systems, recommendation engines, and anomaly detection, and is available on Valkey 8.2 clusters. 🚀 Opinions & Tutorials Jenkins' Flexibility is its Greatest Strength and its Achilles Heel (7 minute read) Jenkins' challenges in enterprises stem from poor governance rather than flaws in the tool itself, as unchecked plugin sprawl, inconsistent configurations, and weak access controls create fragility and maintenance burdens. With centralized governance, automation, and compliance frameworks like those provided by CloudBees, Jenkins becomes a scalable, secure, and enterprise-grade CI/CD solution that enables faster, more reliable software delivery. Salesforce Commerce Cloud migrates from Self-hosted Prometheus to Amazon Managed Service for Prometheus (8 minute read) Salesforce Commerce Cloud migrated from a self-hosted Prometheus and Thanos stack to Amazon Managed Service for Prometheus, achieving a 40% reduction in AWS costs and eliminating monitoring-related maintenance. The new setup improves scalability, reliability, and cross-cluster visibility. A deep dive into BPF LPM trie performance and optimization (9 minute read) A deep dive into the BPF LPM trie, a data structure crucial for network packet routing, revealed performance bottlenecks when storing millions of entries, such as entry lookup times taking hundreds of milliseconds and freeing maps locking up a CPU for over 10 seconds. Benchmarks highlighted that freeing a BPF LPM trie with 10K entries can cause soft lockup messages in production, with throughput decreasing to around 1.5 million ops/sec at 1 million entries due to L1 dcache and dTLB miss rates. 🧑‍💻 Resources & Tools Platform Engineering 3.0 (Sponsor) Learn about the evolution of platform engineering, practical AI use cases, and required skills for modern platform engineers.
