Deliver the right solutions on the leading cloud platform

Cloud Consultancy by SUDO Consultants

As an esteemed AWS Partner, SUDO Consultants leveraged their extensive cloud expertise to transform Nexum’s digital infrastructure. This comprehensive overhaul was not just a technological upgrade but a strategic reimagining of Nexum’s operational framework.

SUDO Consultants approach was multifaceted: initiated the transformation by implementing modern architectural solutions, which were essential in elevating Nexum’s system to a new level of efficiency and scalability. A key component of this modernization was the introduction of robust security measures, ensuring that Nexum’s sensitive financial operations remained impervious to threats while maintaining compliance with industry standards.


The introduction of automated scaling solutions marked another significant enhancement. This capability ensured that Nexum’s infrastructure could dynamically adjust to varying workloads, guaranteeing optimal performance without unnecessary resource expenditure.


At the heart of this transformation were microservices architecture, which brought agility, scalability, and resilience to Nexum’s operations. SUDO Consultants skillfully utilized AWS services, such as Amazon Elastic Container Service (ECS) and AWS Web Application Firewall (WAF), to orchestrate and protect these microservices. This strategic integration of services resulted in a substantial uplift in service delivery, data security, and overall operational efficiency for Nexum.

SUDO Consultants commitment to excellence and their adept use of AWS technologies have not only revitalized Nexum’s infrastructure but also positioned them as a vanguard in the Maritime FinTech space.

Customer Challenge

Prior to SUDO Consultants’ intervention, Nexum’s digital infrastructure was primarily confined to a single server EC2 instance on AWS. This setup, while functional, presented several significant challenges that hindered Nexum’s potential to fully thrive in the dynamic Maritime FinTech sector.

  1. Limited Scalability and Flexibility: The consolidation of both frontend and backend operations on a single EC2 instance led to significant scalability challenges. As Nexum’s user base and transaction volume grew, this monolithic setup struggled to adapt dynamically to increased loads, impacting performance and user experience.
  2. Complex Microservices Management: The backend, hosting critical services such as the Wallet Service, Payment Dispatcher Service, and Security Service, became increasingly complex to manage. Each microservice, while integral to operations, contributed to the complexity of the system. This complexity was compounded by the limitations of the single-server model, making efficient management and updates a challenging endeavor.
  3. Security Risks: Operating both frontend and backend services on a single server posed substantial security risks. In the FinTech domain, where security is paramount, this architecture left the system more vulnerable to attacks and breaches, risking data integrity and user trust.
  4. Inefficient Resource Utilization: The single EC2 instance setup led to suboptimal resource utilization. During periods of low demand, resources were underutilized, while peak times could result in overloading, leading to decreased reliability and performance issues.
  5. Absence of Disaster Recovery and High Availability Strategies: The reliance on a single server meant that Nexum lacked a robust disaster recovery plan. In the event of a server failure or other catastrophic incidents, the potential for data loss and extended downtime was significant.

These challenges, inherent in the single-server infrastructure, not only limited Nexum’s operational efficiency but also posed risks to scalability, security, and reliability – all crucial factors in the competitive FinTech landscape.

SUDO Solution

SUDO Consultants embarked on a strategic modernization journey for Nexum, addressing the core challenges through a series of innovative and forward-thinking solutions.

  1. Containerization and Migration to ECS Cluster: The first step was the containerization of Nexum’s services. By adopting Docker, a leading containerization technology, SUDO Consultants encapsulated each of Nexum’s microservices, including the Wallet Service, Payment Dispatcher Service, and security service, into separate, scalable, and easily manageable containers. These containerized services were then migrated to the Amazon Elastic Container Service (ECS) cluster. This move not only streamlined deployment but also significantly enhanced the scalability and reliability of the services.
  2. Frontend and Backend Separation: Recognizing the need for heightened security and performance, the frontend was separated from the backend and also containerized. It was then deployed on the ECS cluster. This separation was critical in implementing end-to-end SSL encryption, ensuring that all data, whether at rest or in transit, was securely encrypted, thereby fortifying Nexum’s data integrity and customer trust.
  3. Enhanced Security Measures: To further bolster Nexum’s security posture, a Web Application Firewall (WAF) and additional firewall layers were implemented. These measures provided an additional shield against potential cyber threats, ensuring comprehensive protection for the platform’s infrastructure.
  4. DevOps Pipeline Implementation: To facilitate a more efficient and agile development process, SUDO Consultants deployed a DevOps pipeline. This pipeline allowed Nexum’s developers to test and deploy code more rapidly and reliably, enhancing overall productivity and accelerating the delivery of new features and updates.
  5. Creation of Dual Environment Setup: Addressing the critical need for separate development and production environments, SUDO Consultants established two distinct environments for Nexum. This separation marked a significant improvement from the previous setup, where both environments were confined to a single EC2 server. The new dual environment system not only streamlined the development process but also reduced the risks associated with testing and deployment, ensuring a more robust and stable operational framework.

Through these comprehensive solutions, SUDO Consultants successfully modernized Nexum’s infrastructure, aligning it with the best practices of cloud architecture and setting a new standard for efficiency, security, and scalability in the Maritime FinTech sector.
