InfoQ Opens Enrollment for New AI-Assisted Engineering Online Certification Program
InfoQ has opened enrollment for the InfoQ Certified AI-Assisted Engineering Program, a five-week online certification program for senior engineers and architects who already run a coding agent against production code daily, where the open questions have moved past prompting into what the agent is allowed to touch and what catches its mistakes before a human does.

Cloudflare Migrates JavaScript CDN Serving 9B Requests a Day to Its Developer Platform
Cloudflare has migrated cdnjs, its open source CDN for JavaScript and CSS libraries, to its Developer Platform. The new architecture uses Workers, R2, KV, Workflows, Queues, Durable Objects and Containers, consolidating publishing and delivery infrastructure while preserving package contents, URLs and SRI hashes at a scale of 9 billion requests per day.

From Projects to Products: Turning Platforms into Products People Use
Having a platform is not enough; the real challenge is ensuring that it is understandable, usable, and actually adopted by its users. A capability is done when it can be reliably used by others. To evaluate progress, you can ask yourself “Is this being used?” and “Does it reduce friction for users?” This can help align development work with actual user value rather than delivery.

HubSpot Redesigns JITA Authorization with Rule Engine Architecture
HubSpot has redesigned its Just-In-Time Access (JITA) authorization system using a rule engine architecture. The system evaluates access requests through independent rules organized as a directed acyclic graph, adding structured decision metadata, rule-level observability, and governance workflows to replace complex conditional authorization logic.

GitHub Increased Instant Navigation from 4% to 22% by Rethinking Client Side Architecture
GitHub redesigned GitHub Issues navigation using a client-side architecture that combines caching, predictive prefetching, and service workers to reduce perceived latency. The approach uses IndexedDB, in-memory caching, and background synchronization to serve data faster. GitHub reported instant navigation improvements from 4% to 22%, with latency reductions across multiple navigation paths.

How Uber Builds Zone-Failure-Resilient OpenSearch Clusters
Uber explained how it keeps its OpenSearch deployments running during a zone outage. It does this by using OpenSearch's built-in shard allocation and its own isolation-group system, which relies on the Odin container orchestration platform. This way, it maintains both query and ingestion capabilities.

Netflix Cuts Cassandra Read Latency from Seconds to Milliseconds with Dynamic Partition Splitting
Netflix engineers introduced dynamic partition splitting for Cassandra to address wide partitions in time series workloads. The metadata-driven approach detects oversized partitions, splits them smaller units, and routes reads across child partitions. Netflix reported lower read latency from seconds to milliseconds, reduced timeouts, and improved cluster stability while maintaining transparency.

How Lightweight ADRs and Architectural Advice Forums Can Support Architectural Decisions
How we decide is at the core of architecture, and the architecture advice process is a way to decentralize architectural decisions. It needs to be supported by Architecture Decision Records because of the speed at which technology and systems move, and can be complemented by a weekly architecture advice forum.

AI Agent Identity and Permission Challenges: How Uber and Auth0 Are Rethinking Access Control
Uber recently described an internal architecture for propagating identity across multi-agent AI workflows. The design aims to perserve user context, agent provenance, and scoped access as agents delegate work and call internal tools. The case study aligns with Auth0’s view that AI agents need permissions based on delegated authority, scoped credentials, and explicit human approval boundaries.

How Platform Engineering Using Golden Bricks Can Enable Fast and Smooth Delivery
Platform engineering should have a product focus, as developers are customers; they must provide composable, self-service capabilities, golden bricks rather than rigid golden paths, so teams can move quickly while maintaining consistency. Success is measured through adoption, developer experience, and business outcomes such as deployment frequency and change failure rate.

Applying Best Simple System for Now for Software Design
Choosing between building up technical debt and missing delivery deadlines is a false dichotomy, Daniel Terhorst-North argued in his talk Best Simple System for Now. Programmers love to generalize rather than solve the immediate problem at hand, which can make future changes difficult. Instead, we need to build the skills and instincts for keeping things simple.

Netflix Scales "Human Infrastructure" to Manage Global Live Operations
Netflix has introduced a "human infrastructure" layer to manage live broadcasts at scale. Using a low-latency "telemetry hot path" and a Live Operations Centre, the company now balances automated scaling with human oversight. This shift, which mirrors strategies at AWS and Disney+, focuses on maintaining reliability through expert intervention during high-concurrency global events.
