They are a collection of interaction diagrams and the order they happen.
What is software architecture?
Then, draw connections between them to represent interactions and relationships. Use consistent symbols and notations that are standard for the type of diagram you're creating. This includes hardware, software, databases, networks, and any other relevant elements. The DevOps architecture diagram is a visual toolkit essential for modern software development practices.
Container (applications and data stores)
Physical design relates to the actual input and output processes of the system. It focuses on how data is entered into a system, verified, processed, and displayed as output. Let's dive into some fascinating real-world examples that showcase how the principles of system design have been applied to create impressive and impactful digital experiences. These case studies provide a glimpse into how thoughtful design choices can lead to revolutionary solutions and redefine entire industries. Share your software design with anyone, even if they don't own a copy of SmartDraw, with a link. You can also easily export any diagram as a PDF or common image formats like PNG or SVG.
Software architecture diagram
They come in various forms based on their target use cases, and they can be further categorized by the architectural design principles used when they’re created. MySQL is an open-source relational database management system (RDBMS) that stores data in tables and rows. It uses SQL (structured query language) to transfer and access data, and it uses SQL joins to simplify querying and correlation. Leader election is the process of designating a single process as the organizer of tasks distributed across several computers. It’s an algorithm that enables each node throughout the network to recognize a particular node as the task leader. Network nodes communicate with each other to determine which of them will be the leader.
For example, if you have a web application, it seems logical to create a single component diagram that shows all of the components that make up that web application. Using a larger diagram canvas can sometimes help, but large diagrams are usually hard to interpret and comprehend because the cognitive load is too high. And if nobody understands the diagram, nobody is going to look at it. Therefore, understanding UML diagrams is essential for creating well-designed and maintainable software systems.

Types of Documentations
You can use this diagram to understand, design, analyze, and document a process. The same is true for serverless functions/lambdas/etc; treat them as software systems or containers based upon ownership. The purpose of State Machine diagrams is to specify dynamic system behaviors for time-critical, mission-critical, safety-critical, or financially-critical objects. When properly applied (See Usage Notes below) State Machine diagrams are recursively scalable and simulatable. To excel in this round, candidates must demonstrate a deep understanding of architectural principles, problem-solving skills, and the ability to communicate effectively.
One fun thing about this architecture is that you can actually embed it within other patterns, like layered architectures. Events continuously flow through a chain of processor components until no more events are being published for the initial event. In the broker topology, event-processor components receive events directly and are responsible for processing and publishing new events to indicate that an event has been processed. A couple of classic examples of applications with a client-server architecture are the World Wide Web and email. Component diagrams can be created if they add value, but you will want to find a way to automate updates to these diagrams for long-term documentation purposes. Flowcharts are one of the most basic types of diagrams you can make.
System design is a great field for people who like to solve abstract problems and think about the bigger picture. System diagrams typically show the components of a process, including the hardware, software, databases, and people involved, as well as the communication pathways between them. They also show how information is exchanged between the components and how they interact with each other.

Application architecture diagrams work well for both software engineering and cloud-native applications. As a high-level diagram that shows the software’s basic structure, this type includes software components, their relationships, and their properties. It can also convey relationships with external components such as users, databases, and services. This type of diagram uses simple shapes and lines to represent various components. The basic design makes it easier for you to describe the application’s structure to management and other stakeholders. Architectural diagrams are indispensable tools in software development, providing clarity, facilitating communication, and aiding in the strategic planning of software systems.
REST APIs take advantage of HTTP methodologies to establish communication between clients and servers. REST also enables servers to cache responses that improve application performance. Consistent hashing maps data to physical nodes and ensures that only a small set of keys move when servers are added or removed. Consistent hashing stores the data managed by a distributed system in a ring.
We can think of containers as more lightweight versions of virtual machines (VMs) that don’t need their own operating system. All containers on a host share that host’s operating system, which frees up a lot of system resources. Docker is an open-source containerization platform that we can use to build and run containers.
REST applications use HTTP methods, such as GET, POST, DELETE, and PUT. Object storage is the storage designed to handle large amounts of unstructured data. Object storage is the preferred data storage method for data archiving and data backups because it offers dynamic scalability. Communication happens through RESTful APIs at the application level. This type of storage provides immense flexibility and value to systems, because backups, unstructured data, and log files are important to any system. If you’re designing a system with large datasets, object storage would work well for your organization.
The client and server are separate programs that communicate over a network. A web browser and web server are an example of client-server architecture. Once the diagram is complete and validated, finalize it by adding titles, legends, and any other explanatory text. Share the diagram with stakeholders and include it in your documentation. In Miro, you can export your diagram as an image or PDF, or even share the link of the board and start collaborating with your team in real time. This type of diagram can help you to plan out how partner external systems, such as booking agents, fulfillment, ticketing, e-commerce, etc., will integrate with your software.
