Discuss project
Let's Talk

Executive Summary

In an era of rapid technological advancement, traditional financial institutions face the challenge of modernizing their infrastructure to remain competitive and meet evolving customer expectations. HawksCode, leveraging its expertise in cloud technologies and digital transformation, undertook a comprehensive project to guide a legacy financial institution through a large-scale cloud migration and digital overhaul. This case study explores the intricacies of modernizing critical financial systems while ensuring stringent security, regulatory compliance, and minimal disruption to ongoing operations.

Industry Context and Challenges

The financial services sector faces several critical challenges in its journey towards digital transformation:

Legacy Infrastructure:

Decades-old systems, often running on outdated mainframes, hinder agility and innovation.

Data Security:

Financial institutions are prime targets for cyber attacks, necessitating robust security measures throughout the migration process.

Regulatory Compliance:

Strict regulations like GDPR, PSD2, and various national financial regulations require careful consideration during modernization efforts.

Business Continuity:

Ensuring uninterrupted service during the migration process is crucial to maintain customer trust and prevent financial losses.

Data Integration:

Siloed data across various departments and systems poses challenges for creating a unified, cloud-based ecosystem.

Customer Experience:

Meeting the rising expectations of customers for digital, personalized banking experiences is essential for retaining market share.

HawksCode's Innovative Approach

Recognizing the complex nature of these challenges, HawksCode developed a comprehensive, phased approach to cloud migration and digital transformation. Our strategy encompassed several key components:

01

Comprehensive Assessment and Strategy Development

Challenge

Understanding the intricate landscape of existing systems and developing a tailored migration strategy.

Solution:

  • Conducted a thorough analysis of the current IT infrastructure, including hardware, software, and network components.
  • Developed a detailed cloud adoption framework tailored to the financial institution’s specific needs and regulatory requirements.
  • Created a risk assessment matrix to identify potential issues and mitigation strategies.

Technical Deep Dive:

  • Utilized automated discovery tools like AWS Application Discovery Service to map out application dependencies and usage patterns.
  • Implemented a custom-built decision matrix tool using Python and pandas to evaluate each application’s suitability for different migration strategies (rehost, replatform, refactor, etc.).
  • Developed a comprehensive Total Cost of Ownership (TCO) model using Monte Carlo simulations to forecast potential cost savings and ROI over a 5-year period.

02

Hybrid Cloud Architecture Design

Challenge

Designing a scalable, secure cloud architecture that integrates with necessary on-premises systems.

Solution:

  • Implemented a hybrid cloud model using AWS as the primary cloud provider, with certain critical systems remaining on-premises.
  • Designed a multi-region, multi-availability zone architecture to ensure high availability and disaster recovery capabilities.
  • Implemented a zero-trust security model with microsegmentation to enhance overall system security.

Technical Deep Dive:

  • Utilized AWS Direct Connect for secure, dedicated connectivity between on-premises data centers and AWS cloud.
  • Implemented AWS Control Tower for multi-account management, ensuring consistent security and compliance across all cloud resources.
  • Implemented AWS Key Management Service (KMS) with customer-managed keys for encryption, integrated with on-premises Hardware Security Modules (HSMs) for key management.

03

Data Migration and Integration

Challenge

Securely migrating vast amounts of sensitive financial data while ensuring data integrity and compliance.

Solution:

  • Developed a phased data migration strategy, prioritizing non-critical systems before moving to core banking data.
  • Implemented real-time data replication to ensure consistency between legacy and new systems during the migration period.
  • Developed a master data management strategy to create a single source of truth across all systems.

Technical Deep Dive:

  • Utilized AWS Database Migration Service (DMS) for heterogeneous database migrations, with custom scripts for data validation and reconciliation.
  • Implemented Apache Kafka for real-time data streaming and integration between on-premises systems and cloud-based applications.
  • Developed a custom ETL pipeline using AWS Glue for data transformation and loading into a cloud-based data lake built on Amazon S3 and Athena.

04

Application Modernization

Challenge

Modernizing legacy applications while maintaining business continuity and improving performance.

Solution:

  • Adopted a strangler pattern approach to gradually replace components of monolithic applications with microservices.
  • Implemented containerization for improved scalability and resource utilization.
  • Developed a CI/CD pipeline for automated testing and deployment of modernized applications.

Technical Deep Dive:

  • Utilized AWS App2Container to containerize legacy Java and .NET applications, facilitating their migration to Amazon ECS (Elastic Container Service).
  • Implemented a microservices architecture using Amazon EKS (Elastic Kubernetes Service) for orchestrating containerized applications.
  • Developed a custom service mesh using Istio for advanced traffic management, security, and observability across microservices.

05

Security and Compliance Enhancement

Challenge

Ensuring robust security measures and maintaining regulatory compliance throughout the migration and in the new cloud environment.

Solution:

  • Implemented a comprehensive Identity and Access Management (IAM) system with multi-factor authentication and role-based access control.
  • Objective: Minimize total fulfillment cost while meeting Utilized sensor data (vibration, temperature, power consumption) to predict potential failures.service level agreements
  • Implemented continuous compliance monitoring and automated reporting to meet regulatory requirements

Technical Deep Dive:

  • Utilized AWS Identity and Access Management (IAM) with AWS Single Sign-On for centralized access management, integrated with on-premises Active Directory using AD Connector.
  • Implemented AWS GuardDuty for threat detection, enhanced with custom machine learning models built using Amazon SageMaker for detecting financial fraud patterns.
  • Implemented AWS CloudTrail for comprehensive auditing, with logs securely stored in S3 buckets and analyzed using Amazon Athena and Amazon QuickSight for compliance reporting.

Implementation and Change Management

Recognizing the critical nature of financial systems and the importance of stakeholder buy-in, HawksCode employed a comprehensive implementation and change management strategy:

01

Phased Migration:

Implemented the solution in carefully planned phases, starting with non-critical systems before moving to core banking applications.

02

Continuous Communication:

Established regular touchpoints with all levels of the organization, from C-suite executives to end-users, to ensure alignment and address concerns.

03

24/7 Support:
