In many ways, Patterns of Enterprise Application Architecture by Martin Fowler is far superior to Clean Architecture. Fowler describes the patterns he's observed repeatedly in enterprise applications. He gives a simple example if each pattern, describes how it works, and where to use it. I found Patterns of Enterprise Application Architecture to be very readable and applicable to my systems.

Only such architectures, patterns and practices will sufficiently meet the rise of AI-driven programming. Imperative, class-based-OO, brittle languages like Java and even Python (which still does not have multi-line anonymous functions for God sake) will feel their age as dynamic, fluid languages like modern JavaScript, Go, Crystal, Julia, R and others take over.

Patterns of Enterprise Application Architecture is written in direct response to the stiff challenges that face enterprise application developers. The author, noted object-oriented designer Martin Fowler, noticed that despite changes in technology--from Smalltalk to CORBA to Java to .NET--the same basic design ideas can be adapted and applied to solve common problems. With the help of an expert group of contributors, Martin distills over forty recurring solutions into patterns. The result is an indispensable handbook of solutions that are applicable to any enterprise application platform.
This book is actually two books in one. The first section is a short tutorial on developing enterprise applications, which you can read from start to finish to understand the scope of the book's lessons. The next section, the bulk of the book, is a detailed reference to the patterns themselves. Each pattern provides usage and implementation information, as well as detailed code examples in Java or C#. The entire book is also richly illustrated with UML diagrams to further explain the concepts.
The practice of enterprise application development has benefited from the emergence of many new enabling technologies. Multi-tiered object-oriented platforms, such as Java and .NET, have become commonplace. These new tools and technologies are capable of building powerful applications, but they are not easily implemented. Common failures in enterprise applications often occur because their developers do not understand the architectural lessons that experienced object developers have learned.

This book takes a deep dive into many common software architecture patterns. Each pattern includes a full explanation of how it works, explains the pattern's benefits and considerations, and describes the circumstances and conditions it was designed to.
.NET MAUI is the latest multi-platform framework for building mobile and desktop applications with C# and XAML. Building an application across platforms brings a lot of design challenges and considerations. It can be a lot to take in, but fortunately for us, there are a lot of tried-and-true patterns that can be used when building an application that is adaptable, easy to maintain, and test. This is especially important for enterprise applications where requirements and needs often change over time. This book provides real-world examples and explanations to help you build a successful application.
I would like to know if anyone here has experience with cross-platform development using Monotouch, Monodroid and WP7 and to share their experience on application architecture to re-use as much code as possible. The architecture I am considering is as follows:
Within the 3 tier web application architecture, each layer runs on its own infrastructure, and can be developed in parallel by different teams. Such a structure allows to update and scale each tier as needed without impacting the other tiers.
Implementing PWA allows your web application to support offline experiences, background synchronization, and push notifications. This opens access to the functionality that previously required a native application. At the same time, selecting the PWA architecture for your project, you need to keep in mind that the majority of functions are not available on iOS. It is worth it to analyze each specific business case.
Another modern web app architecture is called isomorphic. This is a type of JavaScript application that can run both on the client-side and the server-side. First, the client loads an HTML, where the JavaScript app is uploaded to the browser, then the app starts running like an SPA.
In fact, the new web front-end approach allows us to use all the advantages of the isomorphic architecture type, SSR or SPA, API for mobile devices and linkability. Unlike isomorphic web apps, no restrictions to the language or business logics platform appear. Although it should be noted that developing a web app that uses the new web frontend logic takes longer than the one using SSG or SSR type. To save time for development, we suggest using the Next.js and Nuxt.js frameworks.
AWS serverless services is one of the most popular cloud solutions used to implement popular patterns such as microservices, mobile backends, and Single-Page Applications. The below scheme gives an understanding of how AWS web services can be used for creating a web application using the 3 tier architecture logic we explained earlier.
Oracle Application Integration Architecture (AIA) solutions are delivered as Mediator and BPEL services to create specific integration scenarios between named participating applications. The services interact with each other in various ways, giving rise to diverse interactive styles and patterns for exchanging messages between services. This chapter lists various patterns, highlights the features, and presents guidelines for choosing patterns based on their suitability to an integration scenario.
Oracle AIA architecture enables the requester to be completely decoupled from the provider. For this use case, Get Bill Details is the EBS operation. Each of the billing applications provides ABCS for Get Bill Details. The ABCS of the CRM application is integrated only with the Get Bill Details EBS. The Get Bill Details EBS is implemented as a Mediator routing service. The customer can define the routing rules at this level to identify the appropriate ABCS that must be invoked. For EMEA customers, vendor A's ABCS is invoked; and for North America customers, vendor B ABCS is invoked. Each of the vendor's ABCS is responsible for interacting with their applications to get the bill details and hand them over to EBS in Enterprise Business Message (EBM) format
Oracle AIA architecture enables the requester to be completely decoupled from the provider. For this use case, Get Bill Details is the EBS operation. Only one ABCS for the BRM application exists. This ABCS is responsible for routing the request to the right instance. The ABCS of the CRM application is integrated only with the Get Bill Details EBS. The Get Bill Details EBS is implemented as a Mediator routing service. The customer can define the routing rules at this level to identify the appropriate ABCS that must be invoked. The customer must define a transformation service for populating the target system information in the EBM header. The BRM ABCS uses the information present in the EBM header to route the request to the right BRM instance.
Once you understand how your system fits in to the overall IT environment, a really useful next step is to zoom-in to the system boundary with a Container diagram. A "container" is something like a server-side web application, single-page application, desktop application, mobile app, database schema, file system, etc. Essentially, a container is a separately runnable/deployable unit (e.g. a separate process space) that executes code or stores data.
In addition, the microservices architecture is emerging as an important approach for distributed mission-critical applications. In a microservice-based architecture, the application is built on a collection of services that can be developed, tested, deployed, and versioned independently.
