Custom Built Solutions (Build & Run on AWS)

Custom Built Solutions from ELCA Informatik is a fully managed offering that takes your business requirements and delivers a production-ready, tailored application on AWS - designed, built, deployed, and continuously operated on your behalf. With over 55 years of software engineering experience since 1968, ELCA brings a proven, productized approach to delivering business-critical solutions with high automation and reliability.

You define the business problem. We engineer the solution using modern agentic engineering practices and proven accelerators, then operate it for you across its full lifecycle.

• End-to-end lifecycle management - From initial design and architecture through implementation, deployment, and continuous operation, every phase is covered under a single engagement
• Production-ready workloads on AWS - Each solution leverages scalable, cloud-native AWS services and is delivered ready for real-world use
• Built-in automation, monitoring, and security - Integrated controls span the entire software lifecycle, covering CI/CD pipelines, infrastructure provisioning, observability, and security hardening
• Full application ownership - You retain complete ownership of the delivered application, code, and infrastructure
• Flexible deployment models - Solutions are architected to match your operational and compliance requirements
• OPEX-based consumption model - A single contractual framework simplifies procurement, reduces upfront investment, and lowers delivery risk

Custom Built Solutions follows a structured lifecycle approach:

1. Discovery and Scoping - We work with you to understand your business requirements, constraints, and success criteria. This phase produces a clear scope definition and solution concept.
2. Design - Our engineers create the solution architecture, selecting the right AWS services and patterns for your workload. You receive architecture documentation and a delivery plan.
3. Build - The application is developed using modern engineering practices, with automated testing, infrastructure-as-code, and CI/CD pipelines integrated from the start.
4. Deploy - The solution is deployed into your AWS environment with production-grade configurations, monitoring, and security controls in place.
5. Operate - Ongoing management includes continuous monitoring, incident response, patching, optimization, and SLA-based support to keep your application performing reliably over time.

• Reduce time to production - Proven accelerators and a productized delivery model help move from requirements to a running application faster than traditional custom development
• Lower delivery risk - A structured engagement model with defined phases and deliverables provides predictability throughout the project
• Eliminate operational burden - Continuous operation and monitoring are included, so your teams can focus on business outcomes rather than infrastructure management
• Simplify procurement - One contractual framework covers design, build, and run, avoiding the complexity of coordinating multiple vendors
• Maintain control - Full ownership of the delivered application means no vendor lock-in on your codebase or infrastructure

Founded in 1968 in Lausanne, Switzerland, ELCA Informatik is a long-established software engineering company with decades of experience delivering complex, mission-critical applications. Custom Built Solutions brings that depth of expertise to AWS, combining enterprise-grade engineering discipline with cloud-native agility.
