LDAP Directory Replication for Zero-Downtime Deployment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for deploying LDAP applications from test and stage environments to production environments are inefficient, as they rely on obsolete data and require re-installation and re-configuration, leading to administration overhead and potential production service downtime.
Innovation Solution
A deployment life-cycle model that enables live production updates to the test LDAP directory during pilot testing, allowing for seamless migration of application metadata from the test to the production directory, eliminating the need for re-installation and re-configuration by using one-way replication and reverse replication techniques.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If LDAP applications are tested against a test LDAP directory with copied data, then testing can be performed in isolation, but the test data becomes obsolete and testing effectiveness deteriorates
Solution Approach 1:
The patent sets up one-way replication from the production LDAP directory to the test LDAP directory before testing begins. This preliminary action ensures that the test directory receives live updates from production, preventing data obsolescence and maintaining testing effectiveness throughout the development cycle.
Solution Approach 2:
The patent introduces a replication mechanism as an intermediary between the production LDAP directory and the test LDAP directory. This intermediary automatically synchronizes data from production to test, ensuring the test environment always has current production data without direct manual intervention.
2Productivity
If LDAP applications are re-installed and re-configured in the production environment, then the application can be deployed, but administration overhead increases and production service downtime occurs
Solution Approach 1:
The patent performs all installation and configuration activities in the test environment before deployment. The application is fully installed, configured, and tested against the test LDAP directory with live production data. This preliminary action allows the application to be ready for deployment without requiring re-installation in production.
Solution Approach 2:
The patent uses the test LDAP directory as a copy of the production LDAP directory, updated through one-way replication. The application is tested against this copied but live-updated directory, ensuring compatibility with production without requiring production systems to be interrupted for installation or configuration.
3Reliability
If the test LDAP directory receives live production updates, then testing effectiveness improves, but system complexity increases due to replication configuration
Solution Approach 1:
The patent introduces a replication mechanism as an intermediary that automatically handles data synchronization from production to test LDAP directories. This intermediary manages the complexity of maintaining live data updates, making the process automated and reducing manual configuration burden.
Solution Approach 2:
The one-way replication system operates autonomously, automatically updating the test LDAP directory with changes from the production LDAP directory without requiring manual intervention. This self-service approach maintains data synchronization while minimizing administrative overhead despite the underlying system complexity.
Data Source
AI summary
Systems and methods for testing and deploying LDAP applications are disclosed. A test application may be tested in a test environment including a test directory. The test application may change data stored in the test directory. Furthermore, the test directory may be configured to receive changes from a production directory in a production environment. When the application is ready to be deployed, changes to the test directory are migrated to the production directory through reverse replication or application data migration. The application is configured to connect to the production directory, and the application is thereby deployed in the production environment.
