Introduction
Jeavio’s client, a rapidly expanding scale-up with a live B2B SaaS solution on AWS, had recently secured a significant investment from Microsoft. This investment, however, required them to migrate their application from AWS to Azure.
Built on AWS EC2 with Java services and an AngularJS front-end, the client also grappled with scaling their platform to accommodate growing client demands and maintain delivery velocity.
The client engaged Jeavio to architect and execute this crucial migration.
This case study highlights our strategic approach to cloud migration and digital transformation projects, shedding light on our expertise and the tailored solutions we provided for this particular project.
Approach
Jeavio’s team employed a systematic, four-step approach to ensure a seamless migration for the client:
- Analyze capabilities of the current platform: Assessing the existing AWS infrastructure to gain a comprehensive understanding of the client’s needs.
- Determine gaps and document requirements: Identify any shortcomings and outline modifications required to meet the client’s objectives.
- Map requirements to Azure capabilities: Aligning the client’s needs with Azure’s suite of services and features.
- Execute phased migration: Gradually building and migrating services from AWS to Azure, ensuring minimal disruption to the client’s operations.
The dedicated Jeavio team, comprising a delivery manager, technical architect, software engineers, and test automation engineers, worked collaboratively with our client to deliver a successful migration.
Key Components
This migration project encompassed several critical deliverables, as outlined below. The accompanying architecture diagram provides an overview of the end state following the migration.
- Designing API Contracts: Our team analyzed existing services, refactoring their APIs to create a well-documented, consistent RESTful API for the client’s platform. This approach and leveraging Azure API Management enabled us to develop a robust, API-driven solution.
- Containerization and Deployment: Initially deployed as Java services on EC2 VMs, we containerized the applications and utilized Kubernetes via Azure Kubernetes Service (AKS) for deployment. This streamlined local development and facilitated efficient deployment.
- Data Migration: The application relied on a MySQL database on AWS RDS and a MongoDB database on an EC2 VM. We migrated the relational database to Azure MySQL and utilized MongoDB Atlas to host MongoDB in a managed, scalable environment. Additionally, we introduced Liquibase for automated and version-controlled database deployments.
- Go-Live Planning: After refactoring the application to use updated API contracts, we executed a staged migration of services from AWS to Azure, culminating in the final database migration.
Our comprehensive approach ensured a smooth transition to the Azure platform, optimizing the client’s infrastructure for scalability and efficiency.
Results and Impact
The Jeavio team completed the migration project within six months, delivering a scalable, high-performing, modern web application tailored to the client’s needs.
Notable benefits include:
- Accelerated time to market: The modernized application architecture and automated deployment streamlined the launch of new features.
- Shortened sprint cycles: The ease of local development and production deployment reduced sprint cycles from three weeks to two.
- Enhanced scalability: The platform now supports up to 5x the number of active users without additional development.
- Ongoing collaboration: Jeavio continues to support the client, serving as their primary development team.
Conclusion
The project’s success underscores our team’s expertise in cloud migration, showcasing our ability to deliver transformative results that drive growth and efficiency.
Our strategic approach, deep understanding of technology, and collaborative client partnerships enable us to deliver tailored solutions that drive growth and efficiency.
This case study demonstrates our ability to address complex cloud adoption challenges and support our clients’ ongoing development needs.
