Article: Multi-Cloud FinOps: An Engineering Framework for Cross-Cloud Cost Optimization

Vivek Arora — Fri, 23 Oct 2026 11:00:00 GMT

Multi-cloud flexibility comes with hidden egress costs driven by service placement and communication patterns. This article applies Backend FinOps to cross-cloud architecture, covering cost visibility through FOCUS, workload placement, synchronization models, and CI/CD-integrated cost governance. A controlled experiment shows architecture changes saved far more than rate negotiation alone.

Article: AI Changes the Data Interface, Not the Query Engine

Peihao Yuan — Thu, 22 Oct 2026 09:00:00 GMT

This article presents a disaster-recovery analytics workflow in which an AI agent generates constrained SQL or Python, DuckDB computes reproducible facts from Parquet, and the agent interprets the results. It explains the determinism split, replayable analysis, and four signals for deciding when an embedded engine is sufficient or a managed lakehouse is justified.

Article Series: Agentic AI Architecture

Rafał Gancarz — Wed, 21 Oct 2026 11:30:00 GMT

In this article series, we try to establish agentic AI architecture as a new type of software architecture that will likely dominate the industry for years to come. The articles, written by industry experts, cover various elements and aspects of agentic AI architecture. We aim to present the latest trends and developments shaping the new type of architecture as it enters the mainstream.

Article: Distributed Spring Batch Without a Message Broker

Janardhan Reddy Chejarla — Wed, 21 Oct 2026 09:00:00 GMT

Distributed Spring Batch partitioning already needs a shared, persistent job repository. This article makes that database the whole coordination plane and drops the message broker, sizing work to the live node count, a per-job master with no standing coordinator, compare-and-set claiming that prevents double-execution, two-phase heartbeat failover, and where a broker is still the right choice.

Article: From Microservices to Agents: the Next Evolution of Distributed Systems

Mallika Rao — Mon, 19 Oct 2026 11:00:00 GMT

The article examines the transition from microservices to agentic AI architecture in distributed systems. Microservices allow for functional decomposition, while agentic systems focus on decision decomposition. This shift introduces new complexities in observability, reliability, and system design, highlighting the need for updated architectural patterns and practices.

Article: Cryptographic Foundation of Mobile ID Systems: an ISO/IEC 18013-5 Enterprise Architecture Blueprint

Praveen Kumar Gopalakrishnan — Fri, 16 Oct 2026 09:00:00 GMT

This article provides a framework for asking the right architectural questions before an enterprise commits to an mDL provider or library. It shows which components can be abstracted safely, which trust boundaries must remain visible to the enterprise, what cryptographic and interoperability properties should be verified, and how requirements change across real-world use cases.

Article: Server-Side DPoP and Token Exchange in Spring Security 7

Dhruv Agnihotri — Thu, 15 Oct 2026 09:00:00 GMT

Spring Authorization Server now lives inside Spring Security 7 under the same Maven coordinates, so the upgrade is a version bump. This server-side guide covers enabling DPoP and RFC 8693 Token Exchange, explains why 7.1 apps can silently stop enforcing DPoP until they call .dPoP(), and shows how to combine both into narrowed, sender-constrained tokens for service-to-service and agentic calls.

Article: Composable Commerce: inside Shipt’s Kit Platform

Khurshid Hameed — Wed, 14 Oct 2026 09:00:00 GMT

Shipt launched its Kits feature, enabling quick assembly of themed grocery bundles for events. The platform architecture lets merchandisers easily create store-aware kits, streamlining previously labor-intensive workflows. It utilizes a flexible model of items, shopping lists, and kits to ensure kits display accurately based on local inventory and customer needs.
