Modernizing APIs and Serverless Architecture with AWS

In collaboration with 1CloudHub, an Indian fashion accessories company successfully modernized their APIs and infrastructure using AWS services, transitioning from a monolithic to a microservice/serverless architecture.


Our case study focuses on an Indian products company, a part of a large conglomerate, specializing in the manufacturing of fashion accessories like jewellery, watches, and eyewear. The company embarked on a journey to modernize their existing monolithic APIs and infrastructure.


The Challenge

The customer recognized the limitations of their monolithic architecture and sought to transition towards a more flexible and scalable microservice/serverless model.


1CloudHuub, suggested to leverage AWS services, specifically API Gateway, Python, and DynamoDB. The specific challenges they faced included:


  1. Migration from Java-based API: The existing APIs were based on Java and hosted on Tomcat, with a backend database using MS SQL Server. The customer wanted to migrate these APIs to a modern AWS stack.

  2. Designing DynamoDB Table: A key aspect of the migration involved designing an optimized DynamoDB table to store and manage the API data effectively.

  3. AWS DynamoDB Sizing: Configuring the Read Capacity Units (RCU) and Write Capacity Units (WCU) of DynamoDB was crucial to ensure optimal performance and cost-efficiency.

  4. Implementation of AWS Standard Tokenization: The customer required the implementation of AWS standard tokenization, specifically using API keys, to enhance security and access control for their APIs.

  5. API Build and Exposure at API Gateway: The new APIs needed to be built using Python Lambda functions and exposed through the AWS API Gateway, providing a unified interface for their microservices.


The Solution

To address the customer's requirements, 1CloudHub, an Advanced Tier partner with expertise in migration and modernization on AWS, provided a comprehensive solution:

  1. Preparation and Design: The 1CloudHub team prepared a detailed design document outlining the migration strategy and architecture for the new APIs. This document served as a blueprint for the entire project.

  2. Sizing and Provisioning: The team carefully analyzed the workload and requirements to determine the appropriate sizing for the AWS API Gateway, ensuring optimal performance and cost-effectiveness.

  3. AWS DynamoDB Configuration: 1CloudHub designed and provisioned a suitable DynamoDB instance, considering the required Read and Write Capacity Units to handle the expected workload.

  4. Development and Testing: The team developed the APIs using Python Lambda functions and integrated them with DynamoDB. Rigorous unit testing was performed to validate the functionality and ensure data consistency.

  5. API Gateway and Tokenization: The APIs were exposed through the AWS API Gateway, providing a secure and unified entry point for the microservices. AWS standard tokenization, using API keys, was implemented to enhance security and control access to the APIs.


The successful implementation of the solution led to several significant outcomes for the customer:

  1. Automated API-Driven Cloud Solution: The customer achieved an automated, scalable, and efficient AWS solution, enabling them to handle increased workloads and rapidly respond to market changes.

  2. Infrastructure as Code: The entire infrastructure, including the APIs, API Gateway, Python Lambda functions, and DynamoDB, was provisioned and managed as code, allowing for easier deployment, maintenance, and scalability.

  3. Secure and Standardized Environment: By implementing AWS standard tokenization and leveraging the AWS cloud, the customer established a secure and standardized environment, reducing the risk of unauthorized access and ensuring data privacy.

  4. Improved Efficiency in Provisioning: The migration to AWS and adoption of microservice/serverless architecture improved the efficiency of provisioning cloud infrastructure across the enterprise, streamlining operations and reducing time-to-market.


This case study demonstrates how 1CloudHub partnered with an Indian fashion accessories company to successfully modernize their APIs and infrastructure using AWS services. The customer's transition from a monolithic architecture to a microservice/serverless model enabled them to leverage the scalability, security, and operational benefits of the AWS cloud.
