Demystifying Commerce Platform Technology Architectures

Commerce technology is constantly evolving and terms like "composable," "configuration," and "modernization" are frequently thrown around. Understanding the contrasts between monolithic versus modular architectures and configuration versus customization is important for companies looking to replatform their commerce experience, drive technology adoption, influence strategic decisions, and achieve organizational goals.

Monolithic vs. Modular Architecture

Choosing the right architectural approach is imperative for the success of a replatforming project. There are two types of architectural styles, monolithic and modular, to consider. While both have unique advantages and challenges, understanding the key differences can help teams make informed decisions that align with their project goals and operational needs.

Monolithic Architecture:

Monolith architecture is a traditional software development approach in which an application is built as a unified unit. Here are some key characteristics:

• Single Codebase: All components are part of a single, tightly coupled codebase. This means everything within the application is interconnected, which can simplify initial development but complicate future changes.
• Unified Deployment: The entire application is deployed as one unit. If you need to update one part, the whole application has to be redeployed. This can lead to longer deployment times and increased risk of downtime.
• Tight Coupling: Components are often interdependent, which makes it harder to isolate and fix issues. A problem in one part of the application can easily affect other parts.
• Scalability: Scaling a monolithic application can be challenging because you have to scale the entire application, even if only one part needs more resources. This can lead to inefficient use of resources.
• Development Speed: Initially, development can be faster because everything is in one place. However, as the application grows, it can become more complex and harder to manage, slowing development and increasing the risk of bugs.

Monolithic architecture is often easier to start with, making it a popular choice for smaller projects or startups aiming for a quick market entry. However, as the application grows, this architecture can become increasingly complex and challenging to scale and potentially turn into a bottleneck over time.

Modular Architecture (Composable):

Modular architecture is a design approach where a system is divided into separate, self-contained modules that can be developed, tested, and maintained independently by supporting multiple commerce capabilities. Here are some key characteristics:

• Multiple Codebases: The application is divided into smaller, independent services, each with its own codebase. Teams can work on different services simultaneously without interfering with each other.
• Independent Deployment: Each module or service can be deployed independently. This allows for more frequent and targeted updates, reducing the risk of downtime and making it easier to roll back changes if something goes wrong.
• Loose Coupling: Services are loosely coupled and communicate through APIs, making isolating and fixing issues easier. This leads to greater flexibility in choosing the best technology stack for each service.
• Scalability: You can scale individual services independently based on their specific needs for increased efficiency. This provides granular control over resource allocation and can lead to cost savings.
• Development Speed: Teams can work on different services without interfering with each other, which can speed up development. However, managing multiple services can add complexity, requiring robust DevOps practices and tools.

Modular architecture (composable) provides scalability and flexibility, making it an excellent choice for larger projects or organizations that need to scale quickly and efficiently. However, it can be more complex to manage than other architectural styles.

Monolith vs. Modular Architecture: How Do You Choose?

Both architectures have their pros and cons. It’s important to make your decision based on a variety of factors including the size and complexity of the project. Smaller projects may benefit from the simplicity of a monolithic architecture, while larger, more complex projects might require the flexibility and scalability of microservices. You also need to consider your team structure. If you have a large, distributed team, a composable architecture allows different teams to work independently on other services. However, smaller teams might find it easier to manage a monolithic application. Scalability needs are another factor; if you anticipate the need to scale different parts of your application independently, a better choice is composable.  

Look at your technology stack, if you want to use different technologies for different parts of your application, you will need the flexibility of a modular architecture. Lastly, don’t forget about your deployment and maintenance requirements. If you need to deploy updates frequently and uptime is critical for your application, composable can provide more granular control over deployments.

While monolithic architecture has its place, the dynamic nature of the commerce industry makes modular architecture a more suitable choice for businesses aiming to boost website conversions, average order value, and traffic through improved SEO and customer loyalty. The capacity to adapt and enact changes quickly is a key driver of success in a competitive commerce environment.

Configuration vs. Customization Development

When working with software systems, it’s important to understand the available approaches for tailoring software for specific business needs. Two primary methods are configuration and customization. Both have unique advantages and challenges. Choosing the right approach depends on the requirements and constraints of the project.

Configuration:

Configuration is about using existing software capabilities and features tailored to your needs.

• Ease of Use: Configuration uses built-in options and settings and doesn’t require altering the underlying code. It’s typically user-friendly and can be done through the platform’s user interface or admin panel.
• Budget: Since you are using existing features, configuration is cost-effective and increases speed to market.  
• Flexibility: You are limited to the options and settings the platform provides, and you can only change what the platform allows you to change. This can be a limitation if you have specific requirements that the platform doesn’t support.
• Maintenance: Easy to maintain because you are using standard platform features. Updates and upgrades are usually straightforward, reducing the risk of introducing bugs or breaking changes.
• Examples: Setting up payment gateways, configuring shipping options, adjusting tax settings, and choosing themes or templates.

Configuration is ideal for quick setups and standard needs, leveraging built-in options without altering the underlying code. It’s a good choice for organizations that need to get up and running quickly and don’t have specific requirements.

Customization:

Customization involves adjusting and enhancing your software by creating unique code to achieve specific requirements.  

• Ease of Use: Customizations involve altering and/or extending the platform’s code to add new features or modify existing features. This requires technical expertise and knowledge of programming languages and platform architectures.
• Budget: Customization can be more expensive since there is a need to develop, test, and troubleshoot any of the customizations you are making to the platform, which can also add time to the overall project.  
• Flexibility: Highly flexible. You can make almost any change if you have the technical skills to implement it. This allows for greater control over the final product but can also introduce complexity.
• Maintenance: More complex to maintain. Custom code can introduce bugs and may need to be updated or reworked when the platform is updated. This can lead to increased maintenance costs and longer development cycles.
• Examples: Developing custom plugins or extensions, modifying the checkout process, integrating third-party systems that are not natively supported, creating custom user interfaces or dashboards.

Customization is essential for unique requirements and advanced functionality, offering high flexibility, but increasing maintenance complexity. It’s a good choice for organizations with specific needs that can’t be met with standard platform features. 

Configuration vs. Customization: How Do You Choose?

When considering a new platform, always explore configuration options first, since many modern software solutions offer extensive capabilities that can meet a wide range of needs. If configuration falls short, the next step is to evaluate the gap between what is available and what is needed. This assessment will help determine if customization is justified. Following this, conduct a cost-benefit analysis to weigh the benefits of customization against the costs and risks, considering both short-term and long-term implications. Finally, consult with key stakeholders, including business users, IT staff, and management, to gather input and ensure alignment on the chosen approach.
