AWS SupportENERGY AND UTILITIESSeptember 2025 - September 2025Barcelona, SpainHow we help transform infrastructure and gain agility with AWSThe client came with an infrastructure centralized in a single EC2 instance, hosting the Nginx server, APIs, and frontend. Although this approach worked in the initial phase, clear limitations soon emerged: difficulty in scaling, lack of availability during outages, complexity in maintenance, and a high risk of a failure affecting the entire system.After analyzing their situation, we proposed a re-architecture plan towards a microservices-based model, leveraging AWS managed services. The solution involved separating the frontend from the APIs and deploying them independently using AWS Fargate along with load balancers that allow efficient and secure traffic management.With this new architecture, our client achieved:- Scalability of each component independently, adjusting resources according to real demand.
- Improved fault tolerance, preventing an incident from affecting the entire system.
- Simplified deployments and updates, reducing time and risks in each release.
- Building a solid and agile foundation to evolve their platform without compromising daily operations.
Today, the client enjoys a much more resilient and flexible infrastructure, ready to support their business growth. This experience is particularly relevant for companies still relying on monolithic architectures and looking to transition towards a more scalable, secure model aligned with cloud best practices. - Analytics 4 PeopleData Analytics | Data Engineering | Data Architecture | Big Data | Business | Insights | AIAugust 2023 - Today (2 years and 10 months)Barcelona, SpainWe create Big Data & AI solutions.Dashboard visualization and automation.
