Lavante · Enterprise Architecture Consulting
Solution & Integration Architecture
Building coherent, interoperable enterprise landscapes.
Connect applications, data and business domains with pragmatic solution design and integration architecture.
Solution architecture, integration strategy, API and event-driven architecture, domain-driven design, integration standards, and reference architectures.
Challenges we address
Point-to-point integrations create complexity
Decentralised interface development can lead to inconsistent patterns and tightly coupled systems. We help teams establish a shared architectural direction and a coherent approach to integration.
System responsibilities and data ownership are unclear
Unclear domain boundaries and data ownership can result in tightly coupled integrations and inconsistent interfaces. We use Domain-Driven Design where appropriate to define bounded contexts, clarify system and information ownership, and establish coherent integration responsibilities.
Delivery teams lack consistent integration patterns
Developers need practical guidance on which pattern, standard, technology and platform to use. We turn architectural principles into clear choices that teams can apply in delivery.
How we help
Review application and integration landscapes
Map applications, information flows, dependencies and constraints. Assess how the current landscape supports business capabilities and identify priorities with business and IT stakeholders.
Define bounded contexts, interfaces and ownership
Apply Domain-Driven Design where appropriate to identify business-aligned domains and bounded contexts. Make system responsibilities, interface contracts and information ownership explicit.
Establish an integration reference architecture
Provide a common reference for the development community, defining reusable integration patterns, standards, guidelines and architectural building blocks.
Guide pattern and platform selection
Experienced architecture expertise helps teams resolve complex application, software, technology and integration decisions, select appropriate patterns and establish consistent solution direction.
Embed governance and decision frameworks
Agree decision authority, review practices and responsibilities. Use Architecture Decision Records (ADRs), technical debt and risk management, supported by proportionate reviews and team coaching.
Plan practical transition steps
Balance requirements, delivery constraints and risk when choosing between a coordinated transition and phased migration. Define transition architectures that allow current and future solutions to coexist where needed.
What you receive
Solution architecture designs
Document solution context, stakeholder concerns, constraints and architectural choices. Apply TOGAF as the methodology and use ArchiMate diagrams to communicate the design.
Integration reference architecture
A reusable reference covering integration patterns, standards, platform guidance and responsibilities, giving delivery teams a consistent basis for development.
API and event-driven patterns
Practical guidance on pattern selection, interface design and technology choices, aligned with business needs and operational constraints.
Domain context maps and decision frameworks
Business-aligned domain boundaries, clear ownership and decision guidance, supported by ADRs and a shared view of architectural risks and technical debt.
