MEV in DAG BFT Breaks Honest Ordering
MEV in DAG BFT: how Mysticeti creates transaction ordering bias and why DAG linearization becomes a critical architectural bottleneck
DNS routing for gRPC eliminates thundering herd
DNS routing for gRPC: how changing the Route 53 policy eliminated the thundering herd and distributed the load across 121 million connections without errors
ScyllaDB for Chat Memory in LangChain
ScyllaDB as a backend for LangChain addresses a key issue: preserving dialogue context in RAG systems and scaling without losing state. The problem does not manifest immediately — until the moment the RAG chatbot exceeds a single process. LLMs are inherently stateless: each request begins with an empty context unless the history is manually reproduced. … Read more
Kubernetes DRA Enhances Resource Control
Dynamic Resource Allocation Kubernetes: how DRA 1.36 changes resource scheduling, increases utilization, and manageability in clusters –>
Container Patterns as the Foundation of Architecture
Container patterns as the foundation of container orchestration: how coordination and architecture of distributed systems are built without excessive complexity.
Kubernetes sharded watch reduces API load
Server-side sharded list and watch in Kubernetes changes the behavior of controllers. This is an attempt to eliminate the system ceiling when working with high-cardinality resources. When Kubernetes clusters grow to tens of thousands of nodes, controllers hit scalability limits not where one would typically expect. The problem arises at the list/watch interaction level with … Read more
DocDB architecture for zero-downtime scaling
DocDB architecture: how Stripe scales databases to 5 million QPS through zero-downtime data movement and strict data control.
MRC Protocol for Resilient GPU Networks
The MRC protocol is explained in practice: how GPU networks avoid congestion, withstand failures, and scale to 100k+ GPUs without loss of efficiency.
Redis proxy for highload caching and failure control
Redis proxy becomes a key layer for cache management as load and complexity increase. Let’s explore how an architectural proxy eliminates degradation and stabilizes highload systems. The problem does not manifest immediately — until the moment Redis stops being a “transparent” component and starts dictating system behavior. In the described case, degradation began with an … Read more
Azure IaaS security through defense in depth
Azure IaaS security is built as a layered system, where the failure of one control does not lead to the compromise of the entire platform. This is crucial for resilience against modern attacks that operate simultaneously across multiple fronts. The problem does not manifest immediately — until the classic “perimeter” model stops working. In the … Read more
