Cloud architecture built around your system.
Feneco designs cloud and platform architecture around the workload, the engineering team, the operational requirements and the business constraints of the system in front of us.
We work across cloud-native, container-based, serverless, event-driven and traditional architectures, and choose the model that fits the product. Most of our production work runs on AWS. The same principles apply on other providers.
Architecture starts with the problem
The first step is to understand how the system behaves: traffic patterns, latency requirements, data sensitivity, integration dependencies, release frequency, team capacity and expected growth. The architecture follows from those answers, with the tradeoffs between scale, reliability, security, operating effort and cost written down before anything is built.
Architectural models we work with
Layered and modular
Clear separation between presentation, application, domain and infrastructure. A strong option when maintainability, predictable delivery and clear ownership matter more than distributing the system.
Serverless
Suits event-driven, bursty or highly variable workloads. The execution model, observability, cost profile and platform limits are assessed before serverless is recommended.
Container-based
For services that need predictable execution, continuous availability and control over the runtime. The design covers the networking, deployment, scaling, observability and security around the containers.
Event-driven
Useful when services need to run independently, process work asynchronously or isolate failures. Events are introduced where they bring a clear benefit, and direct calls stay where they are simpler.
What every engagement is built on
Infrastructure as code
Infrastructure is versioned, reviewed and reproducible, typically in Terraform. Environments can be rebuilt from the repository without undocumented console changes.
Secure access by default
Permissions follow least privilege. Pipelines authenticate with short-lived credentials (for example GitHub Actions with OIDC), so no long-lived cloud keys sit in CI secrets.
Private by default
Databases and internal services have no public endpoint unless there is a clear requirement. Network boundaries and access paths are part of the design from the start.
Production-safe delivery
Automated tests, health checks, blue/green or rolling deployments and a rehearsed rollback reduce the risk of each release.
Observability from the first release
Logs, metrics, traces and alerts are designed with the system, so the team can see and diagnose problems in production from day one.
Proven in production
Samuel Santos was Lead Engineer, through Feneco, on the modernization of the Buy Now Pay Later platform of one of Australia's largest banks. The system moved from a rudimentary architecture to a cloud-native, serverless solution on AWS, built with Clean Architecture and Domain-Driven Design and designed to process hundreds of thousands of transactions per day.
The Liren platform runs on infrastructure fully managed in Terraform: VPC, RDS, ECS Fargate, an application load balancer, CloudFront with S3, and Secrets Manager. It deploys through GitHub Actions with OIDC, and the database has no public endpoint.
When the platform work is part of a larger rebuild, see Legacy Modernization.
When Feneco is a good fit
- A cloud environment has grown without a clear architecture.
- A system needs to scale without adding unnecessary operational complexity.
- The team is choosing between containers, serverless, a modular monolith or distributed services.
- Infrastructure cost or reliability is becoming hard to control.
- A migration needs both the architecture and hands-on execution.
The architecture should fit the system first. Feneco makes the tradeoffs explicit and builds platforms your team can keep maintaining as the business grows.
