Vyapar team wanted to address the latency issues faced by their clients on priority and ensure they have a business continuity plan in place . Vyapaar team had sought Searce team’s assistance to rebuild their existing architecture for High Availability and DR while migrating their databases On-prem to RDS-Mysql.
The current setup of Vyapar environment is based on legacy monolithic application architecture where the Application code, DB and all other components are hosted in a single server.
The Vyapar team wanted to Re-Architect, Replatform, then migrate their applications, databases to support their clients in India. Below are the list of high priority items the client is looking for support on.

Searce Solution
Searce expert Team worked with Vyapar’s IT team to gather all the requirements through deepdive sessions to understand the underlying functionality and its features. Based on the workshops we had with the Vyapar team, Searce listed out the current challenges faced by the customers and proposed the use of AWS Managed Services RDS instances and migrated the databases following Highly Available, Secure & robust architecture.
The high level architecture and implementation is as follows:
- Configured Multi-AZ for High Availability
- Encrypted Data at Rest using AWS CMK
- Encrypted Data in Transit by using SSL
- Migrated using Backup and Restore Approach (mysqldump)
- Configured Read-Replicas for Read Intensive queries and Reporting
- Enabled Automated Snapshots with 15 days retention
- Chosen Maintenance Window for automated Patching and upgrades
- Created Cross region read replicas to minimize latency
Business Impact
