About the Company:

Company X, a leading automobile company. Company X has over 2000 retail financing touch points across the country and more than 2000 corporate clients.

Application Development for Efficient Document Management:

The Financial Services company collects a vast number of documents for loan and finance processing relating to loan applications, collections, and validation, bank account details, and so on. These documents are stored electronically using applications in their database in PDF, xlsx, xls, docx, and doc formats.

They had a process in place for integrating documents from various sources, filtering, modifying, and deleting data, but lacked a centralized document system for easy handling of data.

To help Company X integrate and manage its documents more efficiently, Noventiq developed a new application or Document Management System (DMS). The DMS is integrated smoothly with third-party applications that collect the documents; and enables efficient document management. The DMS application plays the role of the central document repository and other LOB applications can store, retrieve, and update the relevant documents with seamless DMS integration.

Noventiq developed the DMS application by following the serverless architecture. Python has been leveraged for the development of the backend RESTful APIs and Angular has been used for the frontend web application. DMS leverages AWS Lambda and Amazon API Gateway as the core AWS services for the deployment of application components. RESTful APIs are hosted on AWS Lambda and published via Amazon API Gateway. Frontend app is deployed on S3 and published via CloudFront.

Faster Data Processing with AWS Lambda:

For the documents to be processed effectively, AWS Lambda picks up, processes, and stores the data and helps run various other processes in the background.

How AWS Lambda Helps Company X:

• Processes huge loads of records within a couple of minutes.
• Continuous scaling of applications as event-triggered code runs in parallel.
• No management or infrastructure provisioning is needed.
• Integrates smoothly with Amazon API Gateway and other connection points.
• Millisecond metering brings down costs drastically.
• Built-in fault tolerance and integration with AWS IAM enhances security.

Amazon API Gateway for Efficiency, Performance and Low Costs:

For ensuring smooth integration of applications, Company X uses RESTful APIs to connect several frontend applications, and backend components. HTTP APIs create RESTful APIs that enable lower costs and latency. The RESTful APIs are published via Amazon API Gateway which in turn accesses by frontend app as well as third party LOB applications for interaction purpose.

The API Gateway is a Managed Service that creates, implements, and manages APIs for Company X. It also helps with the following:

• Access control for APIs using Identity and Access Management (IAM)
• Monitoring of APIs with CloudWatch
• Faster response times by caching APIs using CloudFront.
• Costs reduce as API usage scales up with the Amazon API Gateway

Apart from these benefits, Amazon API Gateway also comes with several securities features, helps monitor performance and can scale up exponentially when coupled with CloudFront. API development is also made easier and cost friendly.

Benefits of AWS Lambda & Amazon API Gateway

While AWS Lambda and Amazon API Gateway help Company X’s DMS with speed, scale, agility, performance, easy management, and cost reduction, the two AWS services bring additional benefits like innovation, modernization of applications, helping to build serverless applications, easy monitoring, robust and flexible security, and efficient API development. The two services integrate very well with other AWS services and are deployed across multiple use cases.
