Scalable, Resilient AWS Infrastructure

---

Requirement | Resilient, secure, and scalable infrastructure

Code10IT required a resilient, secure, and easily managed infrastructure to host its new invoicing application. The solution had to minimize management overhead, allowing developers to focus on application development and expedite time to production.

Solution | AWS-based infrastructure for application hosting

Using an Infrastructure as Code approach, we deployed the AWS landing zone and its associated resources via the AWS CDK framework. This framework enabled standardized, modular components with built-in security controls tailored to their architecture. A comprehensive security layer was implemented to protect inbound and outbound flows, securing both internet-facing and internal traffic. The result was a turnkey infrastructure solution encompassing security, monitoring, logging, scalability, and resilience.

Outcome | Improved developer experience, reduced maintenance, and enhanced security

The application achieved high performance and automatic scaling to match user demand, eliminating the need for a dedicated infrastructure team. With all resources defined in code and a focus on serverless and PaaS services, the team can concentrate on development and accelerate time to market.
