[2602.12875] A Microservice-Based Platform for Sustainable and Intelligent SLO Fulfilment and Service Management
Summary
This article presents CASCA, an open-source microservice-based platform designed to enhance sustainable SLO fulfillment and service management while ensuring developer privacy.
Why It Matters
As applications increasingly rely on microservices, balancing performance and sustainability in service level objectives (SLOs) is critical. CASCA addresses these challenges by enabling intelligent service reconfiguration, which is essential for developers and cloud providers aiming to meet both operational and environmental goals.
Key Takeaways
- CASCA is an open-source platform that facilitates sustainable SLO fulfillment.
- The platform allows for intelligent reconfiguration of services without compromising developer privacy.
- It has been tested in a real-world media streaming service environment, demonstrating its effectiveness.
- CASCA promotes reusability and ease of modification, making it suitable for various applications.
- The integration of decision systems in multiple programming languages enhances its versatility.

As MSA-based applications are deployed to the Computing Continuum (CC), meeting their Service Level Objectives (SLOs) becomes a challenge. Trading off performance and sustainability SLOs is especially challenging. This challenge can be addressed with intelligent decision systems, able to reconfigure the services during runtime to meet the SLOs. However, developing these agents while adhering to the MSA pattern is complex, especially because CC providers, who have key know-how and information to fulfill these SLOs, must comply with the privacy requirements of application developers. This work presents the Carbon-Aware SLO and Control plAtform (CASCA), an open-source MSA-based platform that allows CC providers to reconfigure services and fulfill their SLOs while maintaining the privacy of develo...
