On the other hand, the plug-in modules are meant to enhance the core system in order to produce additional business capabilities. Taking the example of a task scheduler application, the microkernel contains all the logic for scheduling and triggering tasks, while the plug-ins contain specific tasks. As long as the plug-ins adhere to a predefined API, the microkernel can trigger them without having to know the implementation details. Microservices architecture pattern is seen as a viable alternative to monolithic applications and service-oriented architectures.
The components are deployed as separate units through an effective, streamlined delivery pipeline. Owing to its decoupled and independent characteristics, the components are accessed through a remote access protocol. Moreover, the same components can be separately developed, deployed, and tested without interdependency on any other service component. Netflix is one of the early adopters of the microservice architecture pattern.
The architecture allowed the engineering team to work in small teams responsible for the end-to-end development of hundreds of microservices. These microservices work together to stream digital entertainment to millions of Netflix customers every day.
The concept of tuple space — the idea of distributed shared memory is the basis of the name of this architecture. The space-based pattern comprises two primary components — a processing unit and a virtualized middleware.
The processing unit contains portions of application components, including web-based components and backend business logic. While smaller web applications could be deployed in a single processing unit, the larger applications could split the application functionality into multiple processing units to avoid functional collapse.
Furthermore, the virtualized-middleware component contains elements that control various aspects of data synchronization and request handling. They can be custom-written or can be purchased as third-party products. A bidding auction site can be considered as a fitting example for this architecture pattern. It functions as the site receives bids from internet users through a browser request. On receiving the request, the site records that bid with a timestamp, updates the information of the latest bid, and sends the data back to the browser.
A client-server architecture pattern is described as a distributed application structure having two main components — a client and a server. This architecture facilitates the communication between the client and the server, which may or may not be under the same network. A client requests specific resources to be fetched from the server, which might be in the form of data, content, services, files, etc.
The server identifies the requests made and responds to the client appropriately by sending over the requested resources. The functional characteristics of a client and a server is an example of programs that interact with one another within an application.
The functionality of this architecture is highly flexible as a single server can serve multiple clients, or a single client can use multiple servers.
The servers can be classified by the services or resources they provide, irrespective of how they perform. Email is a prominent example of a model that is built using the client-server pattern.
This also helps you to improve the user experience. Imagine a single database receiving multiple similar requests at the same time. Naturally, processing every single request at the same time can complicate and slow down the application process. A solution to this problem is a master-slave architecture pattern that functions with the master database launching multiple slave components to process those requests quickly.
As the title suggests, the master-slave architecture pattern can be pictured as a master distributing tasks to its slaves. Once the slave components finish their tasks, the distributed tasks are compiled by the master and displayed as the result. One must note that the master has absolute control and power over the slave components, determining their communication and functional priorities. What makes this pattern unique is that each slave would process the requests simultaneously, providing the results at the same time.
This also means that the slave operations would not be considered complete until every slave has returned the result to the master. This pattern is well-suited for applications that can be divided into smaller segments for executing similar requests. An appropriate example would be a database application that requires heavy multitasking as its vital component.
A pipe-filter architecture pattern processes a stream of data in a unidirectional flow where components are referred to as filters, and pipes are those which connect these filters. The chain of processing data takes place where the pipes transmit data to the filters, and the result of one filter becomes the input for the next filter. The pipe-filter pattern is best suited for applications that process data in a stream using web services and can create simple sequences to complex structures.
Compilers can be considered a fitting example having this architecture pattern since each filter performs lexical analysis, parsing, semantic analysis, and code generation. A broker pattern is used for structuring distributed systems with decoupled components.
By invoking remote services, components can interact with others in broker architecture patterns. Also, the broker is responsible for all the coordination and communication among the components. Clients, servers, and brokers are three major components of the broker pattern. Generally, a broker will have access to all the services and characteristics related to a particular server.
When clients request a service from the broker, the broker redirects them to a suitable service category for further process. One of the key benefits of this architecture pattern is how it manages operations, such as change, addition, deletion, or relocation, related to objects in a dynamic manner.
Lastly, this architecture pattern separates all communication-related code into layers from the application, allowing applications to run on distributed or single computers. Because of such advantages, broker architecture has been prevalent. In the peer-to-peer architectural pattern, individual components are called peers. A peer can act as a client, a server, or both and change its role dynamically over time.
As a client, a peer can request service from other peers, and as a server, a peer can provide services to other peers. The significant difference between peer-to-peer and client-server architecture is that each computer on the network has considerable authority and the absence of a centralized server. Its capacity increases as more and more computers join the network.
An excellent example of a peer-to-peer architecture pattern would be file-sharing networks like Skype, BitTorrent, and Napster. In BitTorrent, peer-to-peer architecture is used for distributing the data and files on the internet in a decentralized fashion. By using this protocol, one can transfer large video and audio files with the utmost ease. In this manner, you can use peer-to-peer architecture for file sharing, messaging, collaboration, etc.
So far, we have read about the different types of architecture patterns. Now, which architecture would you choose for your software type? You need to make the right choice. Modern applications demand quick thinking and a standardized core that would establish a rock-hard base for the application.
A software architecture pattern sets a solution-based vision for long-term goals, both for the application in question and the company. Working with lead engineers with the knowledge of architecture helps discover the gaps in team composition, ensure effective training, and facilitate growth for the company.

What is IT Architecture We talk a lot about IT architectures, but a lot of times people are confused how to interpret what exactly an IT architecture is. According to Wikipedia "Architecture is the art or practice of designing and constructing buildings". IT market analyst Gartner defines IT architecture as "a series of principles, guidelines or rules used by an enterprise to direct the process of acquiring, building, modifying and interfacing IT resources throughout the enterprise.
And both are right. In one way IT architecture is the process of designing and constructing IT solutions guided by principles and guidelines. But still the definition lacks what should exactly include a well defined architecture deliverable. Types of IT Architectures. The other thing that confuses people is there are different types of IT architectures. The fact is that like when talking about designing a building as a parallel example, there are different levels of architecture such as the overall architecture of the building, floor plans for each floor, and the interior designs.
Enterprise architecture EA is the blueprint of the whole company and defines the architecture of the complete company. It includes all applications and IT systems that are used within the company and by different companies' departments including all applications core and satellite , integration platforms e.
Enterprise Service Bus, API mgt , web, portal and mobile apps, data analytical tooling, data warehouse and data lake, operational and development toolings e. DevOps tooling, monitoring, backup, archiving etc. The EA blueprint shows all IT system in a logical map.
The objective of an enterprise architecture is to focus on making IT work for the whole company and business and fit the companies' and business' goals. It looks at the business strategy and find IT solutions to make it work including innovation and digital enablement. Therefore, an enterprise architect needs to be able to understand both IT and business at a high level.
The intent of EA blueprint is to improve transversal consistency, coherence and efficiency across the whole company while meeting its current and future business and IT objectives. Enterprise architecture is important to clarify how business and IT align and how they support, enable and facilitate each other.
In this article about Enterprise architecture , we discuss more about this specific IT Business alignment. In a company there is one overall corporate enterprise architecture view that all applications are embedded in. However, each and every application has its own solution and technology architecture. So, each application uses enterprise architecture standards and technologies, but designs and builds its own solution and technology architecture to serve its application purpose. N-tier architecture is also called a Distributed Architecture or Multi-tier Architecture.
It is similar to three-tier architecture but the number of the application server is increased and represented in individual tiers in order to distribute the business logic so that the logic can be distributed. This post covers only basic and important points of software architecture and its types which are really needful for a performance tester and performance engineer.

Software Architecture and its types. Performance Testing Tool. There are four types of layer: Presentation Layer: This layer is responsible to display the user interface and manage user interaction.
Application Layer: Application layer also known as Business Layer has all the business logic, rules and policies. The application layer is a bridge between the presentation layer and the data layer. Data Layer: This layer is responsible for storing the data. Service Layer: This layer is responsible to define and implement the service interface and the data contracts.
Service layer communicates with the application layer Tier Architecture 1.
