![]() It presents a detailed view with the goal of communicating the system's individual technology components and their relationships, such as client/server. Component diagramĪ component diagram works like a block diagram but replaces generic functionality blocks with specific technologies. This type of diagram can help explain a system's structure, data flow, and processing flow without distracting the audience with fine details. ![]() They refer to the functionality that's being performed instead of a specific component.įor example, a block diagram might reference a "messaging bus" instead of a specific message-bus technology. The blocks are usually technology agnostic. Block diagramĪ block diagram breaks down a workload into its major functional blocks. These diagrams are good for reaching a common understanding so that you can start deeper discussions or for stakeholder communication. Arrows show the direction of interaction. It includes the main components, their relationships to each other, and the rough order in which data flows through the system. High-level system diagramĪ high-level system diagram serves as a broad overview of a whole workload or of a subsection within a workload. It helps encourage effective communication, problem-solving, and decision-making among stakeholders. Having different types of diagrams allows for a comprehensive understanding of dimensions. Entity-relationship diagrams depict relationships between system components. For instance, flowcharts illustrate process flow. Each dimension type focuses on a specific aspect of the system by providing a level of detail that's specific to that dimension. Workload architecture is complex and multidimensional. If identifying the technology is important, use the official name for the service.įor example, here are the icons for Microsoft services: When you're representing a specific technology, use the latest official icons from your technology provider. Include items such as title, description, last updated date, author, and external references. Metadata also gives context to help viewers understand the diagram's scope and significance. Ensure that a diagram contains metadata that provides essential information about the purpose of the diagram. A diagram is a communication tool, so you need to avoid miscommunication from inaccuracies. For example, don't represent a service in a virtual network if it's not present in that virtual network. Diagrams are abstractions, but don't sacrifice accuracy in the process. Draw from existing data or taxonomies.īe accurate. Use standardized colors, casing, icons, icon sizes, line types, arrow heads, and other representations for similar elements throughout a diagram and across related diagrams. Label lines when the relationships aren't clear. Provide clear, accurate, and meaningful labels for each icon. Prefer using a single-ended arrow to represent the flow from client to server. Double arrows imply a bidirectional dependency. Label all lines without arrows to denote the relationships.Īvoid lines with double arrows. It's hard to know what the relationship is without direction, so use arrows. Be consistent in how you use the lines.Īvoid lines without arrows. Diagrams often show relationships between entities represented as lines. Use widely recognized symbols, icons, and presentation conventions for good readability and interpretation of a diagram.Īvoid ambiguous lines. Diagramming practicesĭiagrams present substantial information without the need for textual explanation. An architect uses multiple types of diagrams throughout activities for design, refinement of requirements, and communication. ![]() Ultimately, the choice of architecture diagram depends on what you're trying to convey and the audience profile. Diagrams are often a composite of multiple types. The list of diagrams in this article isn't exhaustive. ![]() To communicate with intention, an architect must select which diagram is useful in each situation. Diagrams are powerful communication tools that help implementers and stakeholders see the broad vision or dive deep into highly sensitive or nuanced areas of a system. Architects often communicate through diagrams.
