Solution Overview
Problem
Current tax computation systems, both on-premise and cloud-based, face challenges such as high implementation and maintenance costs, service disruptions, data loss, and slow performance, which are detrimental for clients requiring high availability and real-time indirect tax calculations.
Innovation Solution
A hybrid computing system combining on-premise enterprise systems, network systems, and cloud-based management systems, where enterprise computing devices perform tax computations and synchronize results with customizable rules, and an enterprise management system configures and maintains these devices, enabling high availability and redundancy through edge computing and failover operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If cloud-based applications are used for tax computation, then implementation speed is improved, but service availability deteriorates due to service disruptions and downtime
Solution Approach 1:
The system segments the tax computation functionality into independent microservices deployed across multiple cloud providers and on-premise environments. This segmentation allows the system to maintain service availability by routing transactions to operational instances even when some services or providers experience disruptions, thereby resolving the contradiction between fast cloud implementation and service reliability.
Solution Approach 2:
The system implements beforehand cushioning through pre-configured failover mechanisms, redundant computing instances, and disaster recovery plans across multiple environments. When service disruptions occur, these pre-prepared contingencies automatically activate to maintain tax computation availability, addressing the reliability issue while preserving the speed benefits of cloud-based deployment.
2Reliability
If on-premise applications are used for tax computation, then service availability is improved through local control, but implementation cost and complexity deteriorate
Solution Approach 1:
The system applies universality by creating a multi-functional architecture that can operate in hybrid mode, combining cloud-based rapid deployment with on-premise reliability controls. The same tax computation platform can dynamically route transactions between cloud and on-premise instances based on availability requirements, reducing overall system complexity while maintaining high service availability.
Solution Approach 2:
An intermediary layer is introduced between the transaction systems and tax computation engines, providing intelligent routing and load balancing. This mediator abstracts the complexity of managing multiple deployment environments, allowing the system to leverage both cloud speed and on-premise reliability without requiring complex direct integration between all components.
3Loss of time
If cloud-based applications are used for tax computation, then implementation speed is improved, but data security and loss prevention deteriorate
Solution Approach 1:
The system applies local quality by implementing different data security and storage strategies for different data types and transaction stages. Sensitive tax computation data can be processed in isolated cloud environments with enhanced security controls, while critical master data is replicated to on-premise systems for local protection. This localized approach to data management reduces overall data loss risk while maintaining cloud implementation speed.
