How to Diagnose the Root Cause of Istio L7 503 Errors in 3 Steps: From Sidecar to Policy
L7 communication errors such as 503s in Istio are hard to diagnose with ordinary network tools. This guide presents a systematic 3-step diagnostic roadmap—from sidecar behavior, through reverse-tracing VirtualService and AuthorizationPolicy
L4 vs L7 Load Balancers Compared: An Optimal Selection Guide for MSA Environments
A clear comparison of the fundamental differences between L4 (network) and L7 (application) load balancers. From how Round Robin and Sticky Sessions work to a practical selection guide for MSA environments, this covers everything essential
From Diagnosing MSA Performance Bottlenecks to Caching Strategies: A Distributed System Optimization Roadmap
An in-depth, data-driven guide to diagnosing the root causes of slowness in MSA environments. It presents a practical roadmap for optimizing distributed system performance—from monitoring with Prometheus and Jaeger, through Cache-Aside vs.
MSA Distributed Transactions: SAGA Pattern vs. Event Sourcing (ES) Selection Guide
We examine why ACID transactions break in MSA environments and compare how the SAGA pattern and Event Sourcing (ES) actually work. We also contrast orchestration vs. choreography and give practical criteria for choosing the right architectu
Distributed Transaction Consistency in MSA: Replacing 2PC with Saga and Outbox Patterns
Maintaining ACID transactions in a microservices environment is one of the greatest challenges. This guide provides an in-depth analysis of the key patterns for ensuring data consistency in distributed systems, from the limitations of 2PC t
Designing Microservice Communication: API Gateway, Sync vs Async, and When to Adopt a Service Mesh
This guide fundamentally addresses the complexity of inter-service communication in MSA environments. It covers everything architects need to know—from designing a single entry point with an API Gateway and comparing gRPC vs. MQ, to infrast
