Most organizations run dozens (or hundreds) of interconnected systems. Teams need to understand runtime flows, infrastructure realities, and the broader enterprise context. That\u2019s where the supporting views come in \u2014 they complement the core C4 levels by answering questions that the hierarchy alone cannot fully address:<\/p>\n<ul dir=\"auto\">\n<li>How does this system fit into the <strong>larger portfolio<\/strong> of applications across the organization?<\/li>\n<li>What actually happens at runtime when a user performs a key business action?<\/li>\n<li>Where and how are the containers physically or virtually deployed?<\/li>\n<li>When do we need to go all the way down to code-level detail?<\/li>\n<\/ul>\n<p dir=\"auto\">These views are called \u201csupporting\u201d because they are <strong>not<\/strong> part of the primary zoom sequence \u2014 they are used <strong>as needed<\/strong>, depending on the audience, the problem being solved, and the maturity of your architecture documentation.<\/p>\n<h3 dir=\"auto\">The Three Supporting Views at a Glance<\/h3>\n<ol dir=\"auto\">\n<li><strong>System Landscape Diagram<\/strong> A high-level, enterprise-wide view showing <strong>multiple software systems<\/strong> and their key relationships. Think of it as a \u201czoomed-out\u201d System Context that covers the entire organization (or a significant portfolio) rather than just one system. Primary use: Portfolio visibility, identifying integration sprawl, strategic planning, onboarding at company level, enterprise architecture overviews.<\/li>\n<li><strong>Dynamic Diagram<\/strong> Runtime-focused diagrams that illustrate <strong>how elements interact<\/strong> over time for a specific use case, scenario, or business process. Similar to simplified UML sequence or collaboration diagrams, but using C4 elements (persons, containers, or components) and keeping notation lightweight. Primary use: Explaining key workflows, message exchanges, event-driven behavior, onboarding to business processes, debugging tricky integrations, security reviews of runtime flows.<\/li>\n<li><strong>Deployment Diagram<\/strong> Maps <strong>containers<\/strong> (from Level 2) to the <strong>physical or virtual infrastructure<\/strong> where they run \u2014 servers, cloud regions, Kubernetes clusters, load balancers, availability zones, networks, etc. Shows runtime topology, scaling, redundancy, resilience, and infrastructure choices. Primary use: DevOps\/operations discussions, capacity planning, disaster recovery, cloud migration planning, security &amp; compliance audits, cost optimization.<\/li>\n<\/ol>\n<h3 dir=\"auto\">Level 4: Code Diagrams \u2014 A Brief Exploration<\/h3>\n<p dir=\"auto\">Finally, we touch on <strong>Level 4: Code<\/strong> \u2014 the most granular level in the core C4 hierarchy. At this level, diagrams show <strong>implementation specifics<\/strong> inside a component (e.g., UML class diagrams, entity-relationship diagrams, code structure views, or even annotated code snippets). Key points:<\/p>\n<ul dir=\"auto\">\n<li>Used <strong>very sparingly<\/strong> \u2014 only when precise code-level understanding is genuinely required (e.g., critical security paths, tricky domain logic, onboarding to legacy code).<\/li>\n<li>Often leverages existing tools (IDE-generated class diagrams, database modeling tools, auto-generated docs).<\/li>\n<li>Not a primary focus of most C4 usage \u2014 most teams rarely create formal Level 4 diagrams.<\/li>\n<\/ul>\n<h3 dir=\"auto\">Why These Views Complete the Picture<\/h3>\n<p dir=\"auto\">Together, the core levels + supporting views give you a <strong>flexible, comprehensive toolkit<\/strong>:<\/p>\n<ul dir=\"auto\">\n<li>Core levels \u2192 deep understanding of one system<\/li>\n<li>Supporting views \u2192 enterprise context, runtime behavior, infrastructure reality<\/li>\n<li>Level 4 \u2192 surgical precision when needed<\/li>\n<\/ul>\n<p dir=\"auto\">This combination supports many real-world use cases:<\/p>\n<ul dir=\"auto\">\n<li>Enterprise architecture reviews<\/li>\n<li>Onboarding at scale<\/li>\n<li>Incident root-cause analysis<\/li>\n<li>Compliance &amp; audit preparation<\/li>\n<li>Cloud-native migrations<\/li>\n<li>Monolith-to-microservices transitions<\/li>\n<li>Threat modeling &amp; security posture assessment<\/li>\n<\/ul>\n<p dir=\"auto\">In this module, we will cover each supporting view in detail \u2014 including when to create them, what elements to include, common patterns, and pitfalls to avoid \u2014 plus hands-on guidance for generating them (often building directly from your existing Level 1 and 2 models).<\/p>\n<p dir=\"auto\">By the end of Module 5, you\u2019ll know exactly which views to reach for in different scenarios, how to keep them lightweight and valuable, and how to maintain a complete yet manageable set of architecture documentation that scales across the enterprise.<\/p>\n<p dir=\"auto\">Let\u2019s step back for the big-picture landscape, zoom into runtime flows, map the real-world deployment, and touch on code-level detail only when it truly matters \u2014 completing your mastery of the full C4 toolkit! \ud83d\ude80<\/p>\n","protected":false},"featured_media":0,"parent":15037,"menu_order":4,"comment_status":"closed","ping_status":"closed","template":"","doc_tag":[],"class_list":["post-15086","docs","type-docs","status-publish","hentry"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v26.7 -
