Business Challenges  

In the ever-evolving landscape of mortgage lending, the cloud emerges as the catalyst propelling lenders into a future defined by efficiency, security, and unparalleled adaptability. Time to market for products and services was their topmost priority.  

In the fast-paced world of mortgage lending, the need for modern capabilities depends on always having data available. Unfortunately, our client faced on-site limitations, causing unavoidable downtimes, without fault tolerance for their data ecosystem. Such issues affect the ability to respond to market needs and affect customer satisfaction.  

Additionally, security concerns loomed large. Our client faced challenges in implementing comprehensive security measures, leaving sensitive mortgage data vulnerable to potential threats. Without advanced cloud security protocols, there was an increased risk of data breaches and regulatory non-compliance, jeopardizing customer trust. 

Without cloud-based architecture, the challenges persist, highlighting the crucial role of cloud solutions in maintaining services and realizing the full potential of modern mortgage operations. 

On-premises Data Base Challenges  

Our client wanted to improve their product to market time which was being affected by on-premises Oracle databases that were split across various on-premises DB clusters and servers. Our client was facing multiple challenges with the setup, including: 

  • Escalating historical data strained the company’s infrastructure 
  • Sluggish performance and rising ownership costs due to increasing storage requirements 
  • High-licensing expenses for on-premises servers  
  • Expensive and time-consuming backup, redundancy, data retention, and restore processes 

Ultimately, even after choosing to migrate, the downtime risked impacting production, particularly for applications intolerant to significant interruptions during on-premises to cloud database migration. For this the migration had to be carefully planned and executed with precision, avoiding pitfalls. 


The Hexaware Solution 

The customer was looking for a partner for cloud strategy to help them build and manage their Oracle Database infrastructure on the cloud with an optimized environment for better cost management while ensuring high availability, security, and fault tolerance.  

Automated Database Migration Using AWS Database Migration Service 

Our cloud practice teams outlined a solution using the AWS Database Migration Service (DMS) to automate migration, one-time refreshes, ongoing synchronization, and data masking to meet the tight timelines and ensure quality in Database Migration.  

Hexaware migrated the client’s Oracle database over to Amazon Relational Database Service (Amazon RDS) for Oracle, one step at a time. Starting with the smaller footprints, we tested how the queries performed in Amazon RDS for each account, tuned them, then moved on to the next. By running the on-premises database in parallel with the new target, Hexaware also retained a failsafe option and could revert if necessary.  

For larger data footprints, our cloud migration teams wrote custom scripts and used the AWS Database Migration Service (DMS) to help minimize downtime.  

We offered services for strategy, execution, and testing throughout the project, including I/O performance testing that compared database performance on AWS to the performance in the data center. The Hexaware team was instrumental in mapping on-premises Oracle Server to AWS.
