 What we were tasked with was to build a highly extensible scalable system. Challenges like this are what we live for as developers. E-Billing Hub is an automated E-Billing solution developed primarily for law firms to automate their billing cycles. Our ecosystem for E-Billing was growing at an alarming rate. We transact about 4.5 million in voices per year. We decided to move E-Billing Hub to the Azure Cloud. Migration to SQL Azure was seamless. We were able to scale up the database on demand and share our workloads across multiple subsystems. The invoicing system deals with highly complex invoice data, a very complex set of rules. If there's any untimely processing of this data, then people aren't getting paid. We developed a pure pass solution, leveraging Azure artifacts such as storage queues, SQL and NoSQL storage. We use machine learning to analyze the data that we're gathering to gain insight into our market behavior. The benefits we saw from the Azure migration was almost immediate. Managed Azure SQL services have been an instrumental part of our success. We were able to process about 74 validations per second. And in one instance, the Billing Island validation was able to validate 28,000 invoices in less than two hours, which would normally take about two days. One of the biggest business values is to be able to go downstream and target the 27,000 Thomson Reuters customers who are yet to avail the E-Billing service. My team and I are really excited to be part of this transformational journey that's changing the landscape and also helping us grow the business.
