Common Software Architectural Patterns

When you plan or start building your system, you think carefully to decide the most suitable software architecture. From an entrepreneur planning to an enterprise IT manager, choosing the right software architecture is a must. Even large enterprise-scale systems are designed perfectly when you select the most suitable architecture. Prior to any major software development, you need to choose a suitable architecture. It will provide you with the required functionality and quality attributes.

Here are the top 10 software architectural patterns you should understand, before applying them to your design.

10 Common Software Architectural Patterns

A reusable resolution to frequently occurring issues in Software Architecture within a specific context is termed an architectural pattern. While software design patterns are comparable to architectural patterns, the former has a wider application. Below are some of the popular patterns professionals can use:

1. Interpreter pattern

A component that interprets programs written in a certain language is designed using this approach. It primarily lays forth the criteria for evaluating program lines, also referred to as phrases or expressions written in a particular language. The fundamental concept is to establish a class for each language sign.

3. Master-slave pattern

Two parties make up this pattern: the master and the slaves. A final result is calculated from the results that the slave components return after the master component divides the work among identical slave components.

The master database serves as the authoritative source in database replication, and the slave databases are synced to it.

3. Client-server pattern

Two parties make up this pattern: a server and numerous clients. Multiple client components will receive services from the server component. The server responds to clients’ service requests by offering them the pertinent services they have requested. The server also keeps listening to client requests.

4. Broker pattern

Using this paradigm, distributed systems with disconnected components can be organized. Through remote service invocations, these components can communicate with one another. The coordination of component communication is handled by a broker component.

Servers inform a broker about their capabilities (services and traits). When clients ask the broker for a service, the broker directs them to an appropriate service from its registry.

5. Pipe-filter pattern

It is possible to utilize this pattern to organize systems that generate and process streams of data. A filter component encloses each processing stage. Pipes transport the data that has to be processed. These pipelines may be employed for synchronization or buffering needs.

6. Event-bus pattern

This design pattern focuses on events and contains four main parts: an event source, an event listener, a channel, and an event bus. On an event bus, sources post messages to specific channels. Subscribers to specific channels are listeners. When messages are posted to a channel to which they have previously subscribed, listeners are notified.

7. Peer-to-peer pattern

Individual components are referred to as peers in this structure. Peers can act as a server, offering services to other peers, as well as a client, requesting services from other peers. A peer can act as a client, a server, or both, and it has the ability to dynamically switch between these roles over time.

8. Model-view-controller pattern

Although it is not for complete applications, MVC is more of an architectural pattern. MVC primarily has to do with an application’s user interface and an interaction layer. The business logic layer, possibly some service layer, and data access layer are still required.

This is carried out in order to distinguish between internal representations of information and the methods by which information is provided to and accepted by the user. It enables effective code reuse and decouples the components.

9. Blackboard pattern

For issues for which there are no known deterministic solution techniques, this pattern can be helpful. The blackboard pattern is made up of three primary parts.

The blackboard is accessible to every component. New data objects that are added to the blackboard may be produced by components. Components Search the blackboard for certain types of data, which they may locate via pattern matching against the available knowledge base.

10. Layered pattern

Programs that can be broken down into groups of subtasks, each of which is at a different level of abstraction, can be organized using this pattern. Each layer offers services to the layer above it. Usually, there are 4 layers of a general information system.


Software architecture, design concepts, and architectural choices all work together to help a software system achieve its technical, operational, and business goals. Following crucial factors, you must get the software architecture right. During the selection of software architecture types, a team of software developers makes the initial decisions. Before this level, just the business needs are available. Any project’s first set of decisions is critical since poor choices could cause budget and schedule overruns.

Your company’s stakeholders need to be informed of your development. As a visual tool for communication, software architecture helps others comprehend the system you are developing.
