Understanding and Mitigating High Energy Consumption in Microservices
Microservices often consume more energy than monoliths due to distributed overhead. Architects can make design decisions that improve sustainability. This article covers several techniques, such as defining clear service boundaries, optimizing service granularity, using energy-efficient deployment regions, and consolidating workloads.

Using Traffic Mirroring to Debug and Test Microservices in Production-Like Environments
Traffic mirroring has evolved from a network security tool to a robust method for debugging and testing microservices using real-world data. By safely duplicating production traffic to a shadow environment, teams can replicate elusive bugs, profile performance under actual load, validate new features, and detect regressions, ensuring that production remains isolated and user experiences intact.

Cell-Based Architecture Adoption Guidelines
The challenges in building modern, reliable, and understandable distributed systems continue to grow, and cell-based architecture is a valuable way to accept, isolate, and stay reliable in the face of failures. Organizations must ensure that the cell-based architecture is the right fit for them and that the migration will not cause more problems than it solves.

Securing Cell-Based Architecture in Modern Applications
Securing cell-based architecture is essential to fully capitalize on its benefits while minimizing risks. To achieve this, comprehensive security measures must be put in place. Organizations can start by isolating and containing cells using sandbox environments and strict access control mechanisms like role-based and attribute-based access control.

Taking Advantage of Cell-Based Architectures to Build Resilient and Fault-Tolerant Systems
Cell-based architectures offer a robust approach to building resilient systems. They achieve this through the core principles of isolation, autonomy, and replication. Each cell manages its resources and makes decisions autonomously. Observability for cell-based architecture requires a tailored approach to address the unique challenges and opportunities presented by this distributed system design.

How Cell-Based Architecture Enhances Modern Distributed Systems
Cell-based architecture has emerged as a response to many challenges associated with distributed systems. It employs the bulkhead pattern to isolate failures to a fraction of the affected infrastructure footprint and prevent widespread impact. Cells can also help organize large architectures into domain-bound deployment and delivery units, which provides essential sociotechnical benefits.
