5 main patterns of software architecture

First of all, let's see what the software architecture pattern is. Architectural patterns are methods for obtaining the design of well-proven structures so that they can be reused.

In particular, the architectural model is a package of design decisions that is frequently found in practice, has well-defined characteristics that can be reused, and describes architecture. Architectural development can be considered as a process for selecting, assembling and combining patterns. The software architect must decide how to prototype a template, how to adapt it to specific contexts and problem constraints. According to Mark Richards in a book called Software Architecture Patterns, there are five major models of software architecture: microkernel, microservices, layered architecture, event-based, and space-based. 5 important patterns of software architecture 1. Microkernel pattern The microkernel architecture pattern is also known as a plugin architecture. Usually used when software teams build systems with interchangeable components. This template is provided for software systems that need to be able to adapt to changing system needs. The microkernel architecture pattern is a natural pattern for implementing product-based applications. And a product-based application that is packaged as a third-party product and is available for download in a variety of versions. However, many companies develop and publish their in-house business applications, such as software products, along with copies, published notes, and various features. The microkernel architecture template allows you to add additional program features as a plugin to the main program, and also provides the ability to expand as well as separate and separate features. The microkernel architecture model consists of two types of architectural components: the main system and plug-in modules. The program logic is divided between standalone plug-in modules and the main system, which provides the ability to develop, flexibility and separate program features and custom processing logic. The core system of a microcernal architecture pattern typically includes the minimum functions required to make the system usable. Perhaps the best example of the microclip architecture is the Eclipse IDE. Download Eclipse does not provide you with more than one editor. However, once plugins are added, it becomes a fully customizable and useful product. Advantages Excellent flexibility Some implementations allow you to add plugins while the program is running Good portability Ease of deploy Quick response to an ever-changing environment Plug-in modules can be tested individually and can be easily mocked by the main system to demonstrate or prototype a specific feature with minimal or no changes to the main system. It has high performance because you can simplify and customize the program to include only the features you need. Suitable for: Programs that take data from different sources, modify it, and write to different destinations Workflow programs Task scheduling programs 2. Microservices pattern When you write your program as a set of microservices, you are actually writing several programs that work together. Each microservice has its own responsibilities and teams can develop them independently of other microservices. The only dependence between them is communication. Because microservices communicate with each other, you need to make sure that the messages sent between them are also inverted. Advantages You can write, store and deploy each microservice separately Scalability is easy because you can only scale the microservices that need to be scaled It is easier to rewrite parts of the program because they are smaller and less relevant to other parts The program is easy to understand and modify New team members can quickly understand sections and get to work It has a high maintenance and testing capability and allows rapid and frequent development and deploy Ability to deploy independently and enable the team to deploy services without the need for coordination with other teams Suitable for: Websites with small components Corporate data centers with well-defined boundaries Web applications and new businesses that are developing rapidly Development teams that are often spread all over the world 3. Layered architectural pattern The most common architectural pattern is the layered pattern. The layered architecture pattern is an n-tier pattern in which the components are organized in horizontal layers. This is a common way to design more software and means independence. This means that all components are connected but not interdependent. Each layer of the layer architecture pattern has a specific role and responsibility in the program. For example, the presentation layer is responsible for managing all user interfaces and browser communication logic, while the business layer is responsible for enforcing specific business-related rules. One of the powerful features of layered architecture is the separation of dependencies from components. The components in a particular layer only deal with the logic that belongs to that layer. Advantages High test capability Because components belong to certain layers in the architecture, other layers can be mocked, so testing this pattern is relatively easy. High ease of development Because this template is well known and its implementation is not too complicated, also most companies with

Creating skill sets by layers develops programs. This pattern has become a natural choice for further development of business applications. Stable Separate maps can be easily assigned It is easy to update and add layers individually Suitable for: Business applications that do things beyond CRUD operations New programs that need to be built quickly Teams with inexperienced developers who do not yet have a good understanding of other architectures Programs that require strict maintenance and testing standards 4. Event-based template This is the most common asynchronous distributed architecture used to develop highly scalable systems. This architecture includes single-purpose event processing components that listen to events and process them asynchronously. The event-driven architecture creates a central unit that accepts all the data and then assigns it to separate modules that manage a particular type. Advantages Easily suitable for complex and often erratic environments Easily scalable It is easily scalable if new types of events appear Suitable for: Asynchronous systems with asynchronous data flow User Interfaces 5. Space-based template The space-based architecture model is specifically designed to address and solve scalability and concurrency issues. It is also a useful architectural template for applications that have both flexible and unpredictable users. High scalability is achieved by removing the limitations of the central database and instead using duplicate data networks in memory. The space-based architecture is designed to prevent high-performance crashes by splitting processing and storage between multiple servers. Advantages Responds quickly to an ever-changing environment. Although space-based architectures are not generally segregated, they are dynamic, and high-level cloud-based tools allow applications to easily perform push operations for servers, simplifying deploy. High performance is achieved through access to memory data and caching mechanism in this template. High scalability due to the fact that it has little or no dependency on the central database. Suitable for: Large amounts of data such as click streams and user logs Small amounts of data that can sometimes be lost without much consequence Social Networks I hope you found this article useful.
