Executive Summary
Tarin Net, a leading enterprise in [Industry – to be filled], partnered with Babylon Cloud
Gate to embark on a comprehensive digital transformation journey. Facing the
challenges of a monolithic legacy infrastructure and the need for enhanced agility and
scalability, Tarin Net sought to modernize its application portfolio. This case study
details how Babylon Cloud Gate facilitated the migration of 33 applications from a ‘lift
and shift’ approach to a ‘re-platforming’ strategy leveraging a suite of AWS services.
Furthermore, we highlight the successful decomposition of critical monolithic
applications into a microservices architecture hosted on Amazon Elastic Kubernetes
Service (EKS), significantly improving operational efficiency, developer velocity, and
overall business resilience.
The Challenge: Legacy Constraints and the Need for
Agility
•
Prior to their engagement with Babylon Cloud Gate, Tarin Net operated with a traditional
on-premises infrastructure that presented several significant hurdles:
Monolithic Architecture: Core business applications were built as large, tightly
coupled monoliths, making updates, scaling, and maintenance complex and time
consuming.
•
-
Limited Scalability: The existing infrastructure struggled to meet fluctuating
demand, leading to performance bottlenecks and increased operational costs
during peak periods.
Slow Innovation: The rigid nature of the legacy systems hindered the rapid
development and deployment of new features and services, impacting Tarin Net’s
ability to respond swiftly to market changes.
High Operational Overhead: Managing and maintaining the on-premises
environment required substantial resources, diverting focus from strategic
initiatives.
Inefficient Resource Utilization: Static provisioning of resources resulted in
underutilized hardware and increased capital expenditure.
Recognizing these limitations, Tarin Net aimed to transition to a more agile, scalable,
and cost-effective cloud-native environment to foster innovation and maintain a
competitive edge.
The Solution: A Strategic Migration to AWS with
Babylon Cloud Gate
Babylon Cloud Gate devised a multi-phased migration strategy for Tarin Net, moving
beyond a simple ‘lift and shift’ to a more transformative ‘re-platforming’ approach for
their 33 applications. This involved optimizing applications for the cloud environment
without extensive re-architecting, thereby balancing speed of migration with long-term
benefits. A key component of this strategy was the adoption of a microservices
architecture for critical legacy applications, leveraging the power of Amazon EKS.
Re-platforming 33 Applications
For the initial 33 applications, Babylon Cloud Gate implemented a re-platforming
strategy, which involved:
•
Database Modernization: Migrating on-premises databases to managed AWS
database services such as Amazon RDS (Relational Database Service) for relational
databases and Amazon DynamoDB for NoSQL workloads. This offloaded database
administration tasks, improved scalability, and enhanced data resilience.
Containerization: Packaging applications into Docker containers to ensure
consistency across development, testing, and production environments. This laid
the groundwork for seamless deployment on EKS.
Leveraging Managed Services: Integrating applications with other AWS managed
services like Amazon S3 for scalable object storage, Amazon SQS for message
queuing, and AWS Lambda for serverless computing where appropriate. This
reduced operational burden and improved application performance.
Infrastructure as Code (IaC): Utilizing AWS CloudFormation or Terraform to define
and provision infrastructure resources, enabling automated, repeatable, and
consistent deployments.
Monolith to Microservices on Amazon EKS
For Tarin Net’s critical monolithic applications, Babylon Cloud Gate executed a strategic
decomposition into microservices. This involved:
•
Domain-Driven Design: Identifying clear business domains within the monolith to
define independent services, each responsible for a specific function.
Incremental Decomposition: Employing a ‘strangler fig’ pattern to gradually
extract services from the monolith, minimizing disruption to ongoing operations.
Amazon EKS for Orchestration: Deploying and managing the newly created
microservices on Amazon EKS, a managed Kubernetes service. EKS provided the
necessary scalability, high availability, and operational efficiency for containerized
workloads.
Service Mesh Implementation: Implementing a service mesh (e.g., AWS App Mesh
or Istio) to manage inter-service communication, enforce policies, and provide
observability into the microservices ecosystem.
CI/CD Pipeline Integration: Establishing robust Continuous Integration/
Continuous Delivery (CI/CD) pipelines using AWS CodePipeline, CodeBuild, and
CodeDeploy to automate the build, test, and deployment of microservices.
Centralized Logging and Monitoring: Implementing comprehensive logging with
Amazon CloudWatch Logs and monitoring with Amazon CloudWatch and
Prometheus/Grafana to gain deep insights into microservice performance and
health.
Benefits and Results
The strategic migration and modernization efforts undertaken by Tarin Net with the
expertise of Babylon Cloud Gate yielded significant benefits:
•
Enhanced Agility and Faster Time-to-Market: The microservices architecture and
CI/CD pipelines enabled Tarin Net to develop, test, and deploy new features and
updates rapidly, accelerating their innovation cycle.
Improved Scalability and Performance: Leveraging AWS’s elastic infrastructure
and EKS’s orchestration capabilities, applications could now scale dynamically to
meet demand, ensuring optimal performance even during peak loads.
Increased Operational Efficiency: The adoption of managed services and IaC
significantly reduced the operational burden on Tarin Net’s IT team, allowing them
to focus on higher-value strategic initiatives.
Cost Optimization: By optimizing resource utilization, eliminating on-premises
hardware costs, and leveraging AWS’s pay-as-you-go model, Tarin Net achieved
substantial cost savings.
Enhanced Resilience and Reliability: Distributing applications across multiple
microservices and leveraging AWS’s highly available infrastructure improved fault
tolerance and disaster recovery capabilities.
Developer Productivity: The standardized containerized environment and
automated deployment processes empowered developers, leading to increased
productivity and job satisfaction.
Conclusion
Babylon Cloud Gate’s partnership with Tarin Net exemplifies a successful cloud
migration and modernization journey. By strategically re-platforming 33 applications
and meticulously decomposing monolithic systems into microservices on Amazon EKS,
Tarin Net has transformed its IT landscape into a highly agile, scalable, and resilient
cloud-native environment. This foundational shift has not only addressed immediate
operational challenges but has also positioned Tarin Net for sustained growth and
innovation in the digital era.
