Monoliths Often Outperform Microservices
This opinion/analysis argues that monolithic architectures are frequently more efficient and simpler than microservices for most teams. The author cites examples where moving away from distributed microservices reduced latency dramatically, cut infrastructure costs (Prime Video case), and removed scaling limits by processing data in-memory. The piece highlights cloud data transfer costs (e.g., AWS inter-regional fees) and engineering overhead from managing many services, and points to real-world choices by companies like Shopify and 37signals as evidence that large, well-maintained monoliths can be the pragmatic choice for most projects.
Practical architecture advice and cost examples are relevant to engineering and cloud cost decisions across tech teams but are opinion/analysis rather than a platform policy or major industry event.

Key Takeaways & Evidence Grounding
- One team removed their microservices and saw latency drop from 800ms to 12ms.
- AWS bills $0.09 per GB for inter-regional data transfer (as stated in the article).
- Amazon Prime Video's Video Quality Analysis team condensed a serverless architecture into a monolith, which the article says reduced infrastructure costs by over 90% and removed the scaling limit.
- Shopify's main monolithic application reportedly contains 2.8 million lines of code, has over 500,000 commits, processes 32 million requests per minute, and runs 11 million MySQL queries per second on Black Friday (as stated in the article).
- 37signals purchased $600,000 of Dell servers, reducing annual costs to approximately $360,000 and estimating $10 million in savings over five years (as described in the article).

Monolithic vs Distributed Systems: Trade-offs and Decisions
The article explains the differences, trade-offs, and practical decision framework between monolithic and distributed system architectures. A monolith is a single unified application that offers simplicity, low internal latency, and easier reasoning, but it becomes hard to scale, coordinate, and isolate failures as teams and traffic grow. Distributed systems split functionality into independently deployable services that enable independent scaling, fault isolation, and higher availability, but introduce network latency, partial failures, data consistency challenges, and operational complexity. The piece covers specific topics such as latency vs throughput, caching strategies (including edge/CDN caches), replication and redundancy, availability and graceful degradation, congestion control (rate limiting, circuit breakers, load shedding), the “distributed monolith” anti-pattern, and recommends a pragmatic, evolutionary approach: start simple, extract services when pressures (scale, availability, team structure, geography) demand it.
Microservices Cut Latency and Bandwidth for Global E‑commerce
A May 20, 2026 DEV.to post by ruth mhlanga describes a technical case study to enable Bangladeshi creators to sell digital products globally. The team abandoned traditional monolithic e‑commerce platforms in favor of a microservices architecture deployed to regional clouds with a global load balancer. This design reduced latency and bandwidth demands, lowered query costs, and preserved data freshness for near real‑time updates. The author reports measured improvements and reflects on lessons learned and future areas for optimization such as dynamic traffic routing and stronger cache invalidation strategies.
Kubernetes vs ECS: Reassessing Small-Scale Tradeoffs
A platform engineer’s technical analysis argues Kubernetes is increasingly viable—and often preferable—for small-scale deployments previously hosted on Amazon ECS. Based on a migration from a monolithic EC2 + Keycloak setup, the author cites Kubernetes’ declarative YAML manifests, Helm charts, native CronJobs, HPAs and cloud-agnostic ecosystem as enabling portability, modularity and lower long-term costs. By contrast, ECS (and AWS managed services like Fargate, EventBridge and Managed Kafka Connect) is portrayed as tightly coupled to AWS, creating vendor lock-in, operational friction when scaling beyond a few services, and higher resource billing. The piece outlines six small-scale scenarios (observability stacks, cronjobs, Kafka Connect, network policies, monolith migration, long-term scaling) and recommends Kubernetes where teams can invest in maintenance automation and onboarding.
