Application Architecture

What is Application Architecture?

Application Architectures are the techniques and patterns used to define how applications interact with entities such as middleware, databases and other applications.

What are the types of application architecture?

Below are a few application architecture types specified:

Monolithic Architecture – A Monolith Architecture, a single application stack contains all functionality (this architecture is associated with legacy systems). Scaling or updating a single functionality of a monolithic application has implications for the entire application.

Service-Oriented Architecture – In a service-oriented architecture (SOA), individual services are organized around a specific business process. SOA adhere to a communication protocol (like SOAP, AMQ, or MSMQ) and expose each service through a common communication mechanism (platform) called Enterprise Service Bus (ESB). The group of services integrated through an ESB is used by a front-end application to provide value to a business or customer.

Microservices Architecture – Microservices are both architecture and an approach to building applications. With microservices, applications are broken down into their smallest components, independent from each other. Instead of a traditional, monolithic approach to apps, where everything is built into a single piece, microservices are separated and work together to accomplish the same tasks. Each of these components, or processes, is a microservice. The primary goal of using a microservices architecture is to deliver quality applications faster. Microservice are deployed independently. Thus, one doesn’t have to rebuild or redeploy the entire app when changes are made.

Event-driven Architecture – Event-driven architecture is made up of event producers and event consumers. An event producer detects or senses an event and represents the event as a message. It does not know the consumer of the event or the outcome of an event. The event-driven architecture enables minimal coupling, making it a good option for modern, distributed application architectures.
