Overlay Consistency Framework for Legacy Stateful Workloads
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Legacy systems face performance degradation due to inconsistent stateful process workloads and lack of support for modern shared volume interactions, leading to scalability issues and contention across replicated data containers.
Innovation Solution
Implementing an overlay consistency framework that interleaves synchronization processes, prioritizes volume synchronization based on estimated interaction times, and distributes data into stateful sets to balance performance with consistency, without assuming pre-existing consistency mechanisms in legacy systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If legacy stateful workloads are replicated across multiple data containers, then scalability and availability are improved, but data consistency and performance degradation occur due to lack of coordination between replicas
Solution Approach 1:
The patent implements a feedback mechanism where the orchestration system monitors the state of replicated data across containers and dynamically adjusts synchronization operations. The system receives feedback about data access patterns and contention events, then triggers appropriate synchronization actions to maintain consistency while minimizing performance impact.
Solution Approach 2:
The patent introduces an orchestration layer as an intermediary between replicated data containers. This intermediary manages data consistency by coordinating access across containers, handling synchronization operations, and mediating contention events without requiring changes to the legacy workload applications themselves.
2Reliability
If synchronization processes are implemented across replicated data containers, then data consistency is improved, but wait time and performance overhead increase
Solution Approach 1:
The patent implements dynamic synchronization that adapts to actual workload conditions. Rather than using fixed periodic synchronization, the system dynamically determines when synchronization is needed based on real-time monitoring of data access patterns, contention events, and consistency requirements, thereby reducing unnecessary wait times.
Solution Approach 2:
The patent changes synchronization parameters dynamically based on workload characteristics. The system adjusts synchronization frequency, scope, and method according to observed data access patterns and contention levels, optimizing the balance between consistency and performance for different operational scenarios.
3Adaptability or versatility
If legacy systems are modernized with container orchestration, then adaptability and deployment flexibility are improved, but complexity of implementing consistency mechanisms increases
Solution Approach 1:
The patent implements self-service consistency mechanisms where the orchestration system automatically monitors, detects inconsistencies, and triggers synchronization operations without manual intervention. The system self-manages the complexity of consistency maintenance, allowing legacy applications to benefit from container orchestration without requiring them to implement their own consistency logic.
Solution Approach 2:
The patent segments the consistency management function into a separate orchestration layer distinct from the legacy workload applications. This segmentation allows the complexity of consistency mechanisms to be isolated and managed independently, while legacy applications continue to operate with their existing logic unchanged.
4Productivity
If shared volume interactions are implemented across containers, then resource utilization and scalability are improved, but contention and performance degradation occur due to simultaneous access
Solution Approach 1:
The patent implements preliminary actions by pre-establishing coordination protocols and synchronization mechanisms before contention events occur. The orchestration system proactively manages access patterns and prepares synchronization strategies in advance, reducing the impact of contention when simultaneous access events occur.

AI summary
Embodiments of the present invention provide a computer system a computer program product, and a method that comprises identifying replicated data within a respective data container in a plurality of data containers based on an indicative marker that reflects replication; calculating an amount of time to interact with the identified replicated data based on an alert threshold that, when triggered, alerts remaining data containers in the plurality of data containers; and synchronizing the identified replicated data within each respective data container such that reduces a wait time to interact with the identified replicated data based on a priority order of the calculated amount of time to interact, wherein the priority order places higher calculated interaction times higher than lower calculated interaction times.
