Abstract
Microservices architecture advocates decentralized data ownership for building software systems. Particularly, in the Database per Service pattern, each microservice is supposed to maintain its own database and to handle the data related to its functionality. When implementing microservices in practice, however, there seems to be a paradox: The de facto technology (i.e., containerization) for microservice implementation is claimed to be unsuitable for the microservice component (i.e., database) in production environments, mainly due to the data persistence issues (e.g., dangling volumes) and security concerns. As a result, the existing discussions generally suggest replacing database containers with cloud database services, while leaving the on-premises microservice implementation out of consideration. After identifying three statelessness-dominant application scenarios, we proposed container-native data persistence as a conditional solution to enable resilient database containers in production. In essence, this data persistence solution distinguishes stateless data access (i.e., reading) from stateful data processing (i.e., creating, updating, and deleting), and thus it aims at the development of stateless microservices for suitable applications. In addition to developing our proposal, this research is particularly focused on its validation, via prototyping the solution and evaluating its performance, and via applying this solution to two real-world microservice applications. From the industrial perspective, the validation results have proved the feasibility, usability, and efficiency of fully containerized microservices for production in applicable situations. From the academic perspective, this research has shed light on the operation-side micro-optimization of individual microservices, which fundamentally expands the scope of “software micro-optimization” and reveals new research opportunities.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
