Before you start designing your solution, you need to understand the requirements and constraints of your project, such as the business goals, user needs, functional and non-functional specifications, budget, timeline, and technical environment. These factors will influence the choices you make for selecting and integrating the components and layers of your solution. For example, you may need to use a certain data format, protocol, or standard to ensure compatibility and interoperability with other systems.

Careful planning and coordination are required when integrating layers and components in a solution design. Establish unambiguous component interfaces and communication protocols first. Make that the functionality of each layer is in line with the overall goals of the system. Utilise modularization and standardisation to create a smooth integration that enables efficient communication between components. At every integration point, carry out extensive testing to find and fix any possible problems. Establish thoroughly documented APIs to make layer-to-layer communication easier. Continually assess and revise integration strategies to accommodate changing needs and guarantee a unified and expandable solution architecture.

Sometimes while adding new requirements, we may need to think from the perspective of community. Can I create an integration framework which can allow the community to extend the behaviour of my products...
Depending on the requirements and constraints of your project, you may choose different architecture styles and patterns to structure and organize your solution. For example, you may use a layered architecture to separate the concerns of presentation, business logic, and data access, or a microservices architecture to decompose your solution into small, independent, and loosely coupled services. Each architecture style and pattern has its own advantages and disadvantages, as well as implications for integrating the components and layers of your solution. For example, a microservices architecture may require more coordination and communication between the services, as well as more sophisticated tools and processes for testing, deployment, and monitoring.

Often Solution Architecture is thought of as a purely technical role. In reality, the role is a bridge between what the business requires, and how to best provide a technology solution to address those needs. If Business requirements are stated as requirements (rather than embedded within a solution design), the Solution Architect should encapsulate the "volatility" within the business requirements, and create an interface of functionality that has the dependency on core business use cases, and the implementation of that interface is loosely coupled to any technical. The role of a Solution Architect is to provide business agility within the architecture layers, NOT across architecture layers.

It depends upon the needs/requirements, synchronous API/RPC calls, events, batch mode (files, periodic data pulls), options galore, but as an org, you should know your needs, events scale out well and decoupling is great but some systems thrive on consistency and freshness of data, traditional RPC calls can pose scalability challenge but integrity, freshness and consistency of data is highest, more over they make error handling easier. There are no good/bad architectures, mostly trade-offs, depends what's more important to you and what would you be trading off, finding that right balance and always evolving is the key.

In my opinion, we should choose the architectural style which suits the current set of requirements and allows the system to extend whenever possible. There are times when we utilize an architectural pattern for the sake of making technological statements, which should be avoided, keep things simple and extendable...
Once you have chosen the architecture style and pattern for your solution, you need to define the interfaces and contracts between the components and layers of your solution. Interfaces and contracts specify the inputs, outputs, behaviors, and expectations of each component and layer, as well as the rules and protocols for exchanging data and messages. By defining the interfaces and contracts, you can ensure that the components and layers of your solution are consistent, compatible, and coherent, as well as facilitate the integration testing and validation of your solution.

Interfaces and contracts design helps various teams to work independently and develop their parts without knowing the implementation of the other dependent modules. So do it as the first thing in the design lifecycle...

You've provided an accurate description of the importance of defining interfaces and contracts in software development. Interfaces and contracts serve as crucial elements for establishing communication and coordination between different components and layers of a software solution. They define the rules and expectations for how these components and layers interact with each other, ensuring consistency, compatibility, and coherence throughout the system.
Depending on the interfaces and contracts between the components and layers of your solution, you may use different integration techniques and technologies to implement and manage the integration of your solution. For example, you may use point-to-point integration to directly connect two components or layers, or use a broker or a bus to mediate and route the communication between multiple components or layers. You may also use various technologies, such as RESTful APIs, SOAP web services, messaging systems, or event-driven architectures, to enable the integration of your solution. Each integration technique and technology has its own benefits and challenges, as well as suitability for different scenarios and requirements.

I agree that the selection of integration approaches should take into account the benefits, challenges, and suitability for the specific requirements and characteristics of the system.
To ensure the quality and performance of your solution integration, you need to apply the best practices and principles of solution design and integration. These include using loose coupling and high cohesion to reduce dependencies and increase modularity, abstraction and encapsulation to hide implementation details, standardization and interoperability to ensure compatibility with other systems, modifiability and extensibility to enable adaptation to changing needs, reliability and availability to ensure continuity in case of failures or errors, and security and privacy to protect the confidentiality, integrity, and authenticity of components and data.
To support and facilitate the integration of your components and layers in your solution design, you need to use the right tools and methods. These include modeling tools and languages, such as UML, BPMN, or ArchiMate, to visualize and document the design. Additionally, you should use development tools and frameworks, such as IDEs, SDKs, or libraries, to implement and test the design. Furthermore, deployment tools and platforms, such as CI/CD pipelines, containers, or cloud services, should be used to deploy and run the design. Lastly, monitoring tools and systems, such as dashboards, logs, or metrics should be used to track and analyze the performance of the design.
