Software Architecture Design Implies The Quality of The Software

System or the software architecture is the base for any software in which the set of functions which are performed by the software is described and accordingly the design of the system varies for the different technologies. The system or the architecture should take in to account so many factors like the quality, performance, common problems, user requirements, and long-term maintenance. Let me discuss in detail about how the Software Architecture design implies the quality of the software?

If the common problems or the long-term maintenance are not considered when deciding the software architecture then it takes more time and more money from the business. The functional, non-functional, and online requirements are analyzed before deciding the architectural design or architectural system. The software architecture turns in to the different protocol between the components and this improves the speed and quality of the software.  In recent days, the technologies like the cloud technology and the IOT technology demand for the better architecture design for the better performance of the application.

The layered pattern for Java

The structure of the layer works as the subtask to the architecture. This architecture is suitable for the Java EE applications and the four layers communicate to the next higher layer. The presentation layer, business layer, persistence layer, and the database layer are used in different ways to get the desired result. For instance, the JSF is used as the customer delegate as the managed bean component, the customer object can be a local spring bean or a remote EJB3 bean and the data access objects can be implemented as simple POJO’s. This pattern aids to the flow of information which help the customer to retrieve the data with little or no logic. The presentation layer is known as the UI layer, the application layer is known as the service layer, the business logic layer is known as the domain layer, and the data access layer is known as the persistence layer to the desktop application or the E-commerce web applications.

Client and server pattern for Java

This pattern is used to connect the server to the multiple clients. The server provides the services to the client and also listens to the client’s requests after the provision. Java is used for the strong network connection and multi-task threads. Many servers like the commercial and the open source servers for the online applications like email, document sharing, and banking use the client-server pattern. Some of the examples of the server designed with this architecture are Tomcat, Jetty, Resin, and Caucho.

Micro-services and DevOps

Micro-services are easy to write and rewrite the pieces of the application. Small pieces of the application can be re-used for the multiple purposes and make the deployment process easy. Companies which use the agile methodology or DevOps architecture use the Micro-services architecture. The flexibility of deploying the micro-service applications in containers made the micro-service architecture famous. Micro-service architecture is easy to deploy, easy to migrate to the data centers or cloud services. Dockers swarm, Google-developed kubernetes, Apache mesos, and Zookeeper are the popular micro service applications which use the containerized environments.

Master-slave architecture and MySQL database

MYSQL database server is the master and it is copied to the MySQL database servers to read the database. It gives read access to the multiple servers and it is also used for the analysis and failover. The master is referred to as the authoritative source and the slave is synchronized to it. This is used for the database replication.

Broker pattern and the IOT

The Broker pattern is used for the IoT technology. The four models in IOT are the device to device communications, the device to gateway connections, gateway to data systems and between data systems in the data center or cloud. The components in the broker pattern communicate with the help of remote service invocations. The servers which work under the broker communicate about their services and characteristics to the broker which is the main server. Event subscription, asynchronous messaging, reliable messaging, multicasting, publish or subscribe, queues, message brokers, federation, and delegation of trust are some of the architecture used in the IOT technology.

Event-bus pattern and the android development

This design has four major components such as event source, event listener, and channel and event bus. The sources publish the messages and the listeners note the messages that are published in particular channels. Android is an event-driven application and conceptually the different entities or components subscribe to the event bus.


The four ways to identify the flaws in the software architecture are fundamental design principles, gaps in the security control, assess the attack, and analyze the threats. Review of the architecture is important for the development process of any software. Good architecture design improves the performance and the quality of the software.
