Efficient document processing: Transforming customer workflows with AWS Lambda, S3, and OpenSearch 

The client’s documentation upload and chat service was previously hosted on an on-premises infrastructure, which posed multiple challenges. Documents were uploaded on an unpredictable schedule with peaks of high activity and long idle periods.

The number of end users also constantly changed with spikes and idles. This variable load led to excessive operational costs and frequent service disruptions due to the limited reliability and scalability of the on-premises environment.

The client’s main challenge was to migrate the entire service to a secure, scalable, and compliant cloud-based environment. This migration needed to ensure data privacy, high availability, and compliance with industry standards, all while keeping operational costs low.

Without a cloud-native solution, the on-premises infrastructure would continue to struggle with unpredictable workloads and fluctuating user demand, leading to frequent service disruptions and unreliable performance.
Operational costs would have remained high, and maintenance would have required more manual effort, increasing the risk of errors and downtime. Furthermore, ensuring compliance would have been more difficult without the security features of AWS managed services.

Honeycomb Software designed and implemented a modern, cloud-native architecture leveraging key AWS services to address the client’s challenges. This approach was chosen because AWS offers a comprehensive suite of services that could address the client’s needs for a robust, scalable, and secure platform.

As an AWS Partner Network (APN) Partner, Honeycomb Software’s team of AWS-certified developers, engineers, and architects designed a cost-effective cloud solution that maximized the potential of the AWS ecosystem.
The solution involved the following technical implementation:

• AWS S3 (Simple Storage Service): Chosen as a scalable, durable, and secure object storage system for storing the client’s documents. Bucket encryption was enabled to comply with security requirements, and lifecycle policies were added to manage document storage efficiently and securely, which saved costs.
• AWS Lambda: Used for processing documents uploaded to the S3 bucket. Lambda provides a cost-effective, scalable solution by charging only for the compute time consumed, making it ideal for handling intermittent document uploads. Lambda seamlessly integrates with S3, with event-driven triggers automatically invoking the function upon new uploads to ensure real-time processing.
• OpenSearch Serverless: Chosen as a vector storage to simplify setup, management, and scaling while reducing operational overhead. It is used to store and search processed documents, offering full-text search capabilities and efficient querying.
• AWS Transfer Family: A managed SFTP server was temporarily deployed to securely migrate existing documents from the on-premises environment.

This serverless architecture eliminated the need for managing infrastructure, allowing for automatic scaling to handle varying workloads without manual intervention.

The entire document ingestion and processing workflow was automated, significantly reducing operational overhead, minimizing downtime, and improving overall system reliability and performance while optimizing costs and ensuring compliance with data security requirements.

The solution implemented by Honeycomb Software resulted in significant, measurable benefits for the client:

• Operational costs were reduced by approximately 40% due to the automatic scaling of resources, which eliminated waste during idle periods and efficiently handled peak workloads.
• Document ingestion and processing time decreased by 60%, enabling faster availability of information through the intelligent chat interface.
• System downtime was reduced by over 90%, which greatly improved service reliability and user satisfaction.
• Manual intervention and maintenance efforts were cut by 70%, allowing the IT team to focus on innovation.
• Data security and compliance requirements were met consistently, minimizing risk and supporting regulatory standards.
