 As businesses evolve their digital strategy to deliver better customer experiences, one winning strategy is the integration of microservices in composable DXP. But what is a composable DXP solution, and how does the integration benefit your business?

This article explores the integration, its impact on digital transformation and the steps to execute it.

Introduction to composable DXP and microservices

A composable DXP is a set of tools that enable digital marketers to create, manage, and deliver digital experiences over time across multiple channels. These tools are connected by secure APIs. A microservices architecture is a development method where an application is broken down into a small collection of separate, autonomous services that interact via APIs. Composable DXPs benefit from microservices; hence, integrating is the right step for you.

Microservices In Action

Differences between microservices and composable architecture

Although similar, they are different in many ways. For instance, both allow you to reuse and interchange system units. However, microservices have a smaller scope. They focus on small business functions, while composable architectures are broader.

Microservices focus on splitting applications into smaller units, while a composable architecture builds applications from reusable units. Also, microservices focus on specific business needs, while composable DXPs focus on how you can assemble modular tools to meet unique business needs.

Differences between monolithic and composable DXP

A composable digital experience platform allows you to choose and integrate various system units based on your needs. They are not tightly coupled and do not run on one server like in monolithic applications. That makes them more flexible and scalable.

While a composable DXP is modular, a monolithic DXP is an integrated, all-in-one platform. Monoliths are limited in how they can integrate with other tools as they work within the platform. Composable DXPs do not have such issues. By design, they work with APIs and integrate with external tools and services.

Benefits of a composable digital experience platform

A composable digital experience platform integrates your tech stack and enables you to deploy fast. It promotes a flexible and scalable operation. It uses a “best-of-breed” approach to integrate the most suitable stack for your needs. So, you only choose the functions and software you need when you need it. 

Benefits of integrating microservices architecture in composable DXP

A composable digital experience platform uses a headless approach. They are built from various systems that interact through APIs and microservices. 

Integrating microservices in composable architecture enables you to deliver personalized customer experiences across multiple channels. It also enables you to scale separate and autonomous units of the system. You can also develop, test and deploy individual features, leading to faster time to market. 

As microservices are API-driven, they integrate well with third-party services. Hence, it gives you access to more tools and services to enrich the DXP ecosystem.

Steps to integrate microservices in composable DXP

Planning phase

Assess business needs: Assess your business needs and identify your goals. For instance, do you want to add new features or enhance user experience? Next, review your current system to know what it can or cannot do and what functions you can improve.

Define microservices: Next, decide on what services you may consider essential to your digital experience platform. Then, plan the user interface and how the services interact. Also, determine how they exchange data.

Plan for scaling: Plan for future growth and increase of traffic and data volume. Ensure that the system allows you to add, modify or update it to meet your business needs as you evolve.

Implementation phase

Develop and integrate microservices: You can either integrate existing microservices or build new ones. Ensure you use the chosen tech stack and adhere to the design and business logic. Next, configure the APIs to enable the services to interact with each other. 

Set up infrastructure: This part of the integration takes care of how you deploy. You may consider containers like Docker and cloud services. You may also look at orchestration tools like Kubernetes. Consider data storage and set up databases.

Security and compliance: Ensure you adhere to strict security measures and industry standards. Set up secure APIs and ways to validate and authorize users.

Testing phase

Functional testing: A unit and integration test ensures that the system works as it should and also tests API endpoints to make sure they are well set up. 

End-to-end testing: Test the system integration with your composable DXP and test user acceptance to see how users interact with the system. That way, you can get their feedback.

Load and performance testing: Finally, you want to test how the system works in reality. So, you can simulate high traffic to enable you to see how the system performs under stress. This test also enables you to know if the system can scale.

At the end of the three phases, you adopt an agile approach and monitor the system, get feedback from users, and improve it further if needed. 

Role of microservices scalability in digital transformation

Being able to scale microservices enables digital transformation in many ways. You can increase your speed to market, reduce development time and respond faster to market dynamics. As you can modify or update microservices on the go, it enables you to respond and adjust to new market demands. It also promotes agile development, enabling you to scale as user demands grow.

Microservices also improve how you allocate resources. You can update or modify parts of the system without affecting the whole application, enabling you to focus your resources on where you need them the most. 

Microservices also promote continuous integration and deployment. Hence, you can release new products faster and also roll out updates and new features. That way, you can stay competitive.

Benefits of integrating microservices architecture in composable DXP

Improved resilience: Microservices excel in fault isolation. That ensures that if a single part of the DXP fails, it does not affect the entire system. The integration enables you to limit the impact of failure.

Enhances user experience: Integrating microservices in composable DXP gives you access to data on how customers interact with the system via each autonomous service. You can use that to deliver more personalized user experiences.

Smoother third-party integrations: Microservices are API-driven. So you can add more tools and integrations to your composable digital experience platform. That enables you to do more.

More flexible and scalable operations: Since services are decoupled, you can quickly update them or add new features. You can remove features that offer little or no impact to the DXP. You can also scale one or several parts of your composable DXP based on demand.

Challenges of integrating microservices architecture in composable DXP

Integration complexities: As services use separate resources, they have different life cycles and, at times, technology stacks. In the initial stages, you may find it hard to manage these complex arrangements.

Security concerns: Since every service is separate, it opens up more surface areas for potential attacks. It can also be hard to enact security strategies across services due to their complexity. 

Higher overheads: After integration, you have to deploy, scale and monitor each service. That could bump up your overhead compared to using a monolithic architecture. Although you can automate the process with CI/CD pipelines and container tools, they require extra setup time and resources.

Case studies

Burberry and Emma are two successful composable DXP integration examples.
