A deployment diagram helps you to plan strategic application and service upgrades to optimize your resources so they can handle additional process requests and workloads as your organization grows. A DevOps architecture diagram is similar to a process flow diagram. It visualizes the operational flows of application deployments, illustrating how processes flow and what is being deployed to internal and external systems.
You would use this type of diagram to look for ways to improve the application deployment process. You will need to update and improve your DevOps architecture to keep up with continual improvements of deployment tools and changes to other interfacing systems architecture. As the name suggests, data architecture diagrams demonstrate how and where the data flows, is processed, and used. It includes components that define how data is collected in the system. If you are looking for ways to update and streamline data storage resources you would turn to a data architecture diagram.
Data collection and consumption is constantly increasing, so you will need to revise and update your data architecture frequently. Your drawings can be as low-tech as a pencil and paper or as high-tech as a cloud-based intelligent diagramming app like Lucidchart.

It is important to understand this context to properly design the system and remind yourself to integrate with external systems. This diagram displays the neo-banking digital platform presented by a blue rectangle in the center. There are different tools you can use to create the context diagram.
You can also use PlantUML to leverage diagrams as code. Let's say we want to draw the aforementioned diagram for a neo-banking digital platform with uml:. We define a person, a system, external systems and the relations between them. Rel predicate has 3 parameters as well, but they are different: a key of one entity, a key of another and a name of the relation.
Basically you can draw a context diagram in any drawing tool you'd like. Several great examples can be found here. Context diagram is a crucial view which provides the highest level understanding on the people and systems your future system will interact with. Containers don't mean docker containers here. Container is an any deployable entity or data storage from the C4 perspective.
It can be a mobile application, a website, a VM, a docker container, a database or an object storage; whatever you can deploy. In my experience this diagram is the most complex and it gains the most attention in the same time.
That mean it is almost the main diagram you have to work on! The trick here is you are zooming in into your system. What was a single rectangle, now consists of some rectangles and arrows. Those rectangles are containers now. Container diagram provides insight into which deployable items your backend consist of and how those components talk to each other.
The first two diagrams show how the elements of the system relate to each other. However, they can not demonstrate what happens in your system. For example, a user sign ups for your system. Which components are involved? What actions are triggered? How the components interact with each other? Sequence diagram can answer these questions. At the top we see interacting entities: persons, web and mobile applications, external systems, services and data stores. Each entity has a vertical line underneath.
The interaction between services is notated with horizontal arrows between the vertical lines. Those arrows can be of different types depending on whether this is a synchrornous operation or an asynchronous.
The grey rectangles shows that process is taking some time and the length should indicate the duration: the longer the rectangle, the longer the time. Unfortunately, OmniGraffle is not suitable for sequence diagrams. Therefore I use draw. The latter is a good choice because you can choose either to draw the diagram manually or use the UML Sequence diagramming.
Often, the diagrams themselves aren't the end-goal, with teams using the diagrams to answer other questions that they have, such as, "what dependencies does component X have? If this is the case, building a model will allow you to answer such questions, without the additional effort of creating a diagram.
In other words, once you have a model, you can visualise it in a number of different ways images 3 and 4, above , helping to answer the real questions that you are seeking to answer.
Diagrams certainly are a fantastic way to communicate software architecture, but other visualisations can sometimes help answer the real underlying questions that you might have. If you're interested in using the C4 model or building tooling to support it, here is some information about the basic metamodel. The following resources are recommended if you're looking for more information about visualising software architecture and the C4 model.
It's a short guide to visualising, documenting and exploring your software architecture. If you're considering whether the C4 model is right for your team, the best approach is to just try it. Set aside an hour, grab a whiteboard, and draw a System Context diagram for whatever you're working on. If you find that useful, set aside another hour to draw a Container diagram for the same software system. For many teams, those two levels of detail are sufficient. If you think there's value in drawing Component diagrams, then try that out too.
Component diagrams tend to be more volatile though, so you should really start to look at automating this level of detail where possible, so that the diagrams always reflect the code. If you have retrospectives as a part of your working practices, don't forget to discuss the diagrams.
Are they useful? Do people use them? Are they kept up to date? Could we use more detail? Or are our diagrams too detailed, and falling out of date quickly? Is the tooling sufficient? Does everybody have access to the diagrams when needed? In-person and online training is available to help you introduce the C4 model, or scale C4 model knowledge, within your organisation.
For design sessions, you might find a whiteboard or flip chart paper better for collaboration, and iterating quickly. For long-lived documentation, the following modelling and diagramming tools can help create software architecture diagrams based upon the C4 model.

It shows the people who use it, and the other software systems that the Internet Banking System has a relationship with. Personal Customers of the bank use the Internet Banking System to view information about their bank accounts, and to make payments. The Internet Banking System itself uses the bank's existing Mainframe Banking System to do this, and uses the bank's existing E-mail System to send e-mails to customers.
A colour coding has been used to indicate which software systems exist already the grey boxes. In this slightly modified example, the dashed line represents the boundary of the bank, and is used to illustrate what's inside vs what's outside of the bank. This is an example Container diagram for a fictional Internet Banking System.
The Single-Page Application is an Angular application that runs in the customer's web browser, providing all of the Internet banking features. Alternatively, customers can use the cross-platform Xamarin Mobile App, to access a subset of the Internet banking functionality.
The dashed line represents the boundary of the Internet Banking System, showing the containers light blue inside it. Additionally, a cylinder shape has been used to represent the database. This is an example Component diagram for a fictional Internet Banking System, showing some rather than all of the components within the API Application.
The dashed line represents the boundary of the API Application, showing the components light blue inside it. This is an example and partial UML class diagram for a fictional Internet Banking System, showing the code elements interfaces and classes that make up the MainframeBankingSystemFacade component. It shows that the component is made up of a number of classes, with the implementation details directly reflecting the code.
Introduction Ask somebody in the building industry to visually communicate the architecture of a building and you'll be presented with site plans, floor plans, elevation views, cross-section views and detail drawings. Abstractions In order to create these maps of your code, we first need a common set of abstractions to create a ubiquitous language that we can use to describe the static structure of a software system.
Person A person represents one of the human users of your software system e. Software System A software system is the highest level of abstraction and describes something that delivers value to its users, whether they are human or not. Container applications and data stores Not Docker! Client-side web application : A JavaScript application running in a web browser using Angular, Backbone. JS, jQuery, etc. Server-side console application : A standalone e.
Serverless function : A single serverless function e. Amazon Lambda, Azure Function, etc. Blob or content store : A blob store e. Akamai, Amazon CloudFront, etc. File system : A full local file system or a portion of a larger networked file system e. Shell script : A single shell script written in Bash, etc.
Component The word "component" is a hugely overloaded term in the software development industry, but in this context a component is a grouping of related functionality encapsulated behind a well-defined interface. Core diagrams Visualising this hierarchy of abstractions is then done by creating a collection of Context , Container , Component and optionally Code e. Level 1: System Context diagram A System Context diagram is a good starting point for diagramming and documenting a software system, allowing you to step back and see the big picture.
Scope : A single software system. Recommended for most teams : Yes. Level 2: Container diagram Once you understand how your system fits in to the overall IT environment, a really useful next step is to zoom-in to the system boundary with a Container diagram.
Level 3: Component diagram Next you can zoom in and decompose each container further to identify the major structural building blocks and their interactions. Scope : A single container. Level 4: Code Finally, you can zoom in to each component to show how it is implemented as code; using UML class diagrams, entity relationship diagrams or similar.
Scope : A single component. Supplementary diagrams Once you have a good understanding of the static structure, you can supplement the C4 diagrams to show other aspects.
System Landscape diagram The C4 model provides a static view of a single software system but, in the real-world, software systems never live in isolation.
Scope : An enterprise. Dynamic diagram A dynamic diagram can be useful when you want to show how elements in a static model collaborate at runtime to implement a user story, use case, feature, etc. Scope : One or more software systems.
