The need to integrate multiple applications and services has become more urgent than ever. As a result, many organizations have turned to APIs (Application Programming Interfaces) as a way to enable seamless communication between different systems. However, this approach, when applied to internal use cases, can lead to higher costs and limited flexibility.

The challenges of legacy API-led approaches

When it comes to internal reuse, traditional API-based approaches, while effective, can also have some unintended drawbacks. Here are a few examples:

• Tight coupling: APIs can create tight coupling between applications, making it difficult to evolve or change one application without impacting others. This leads to a cascading level of effort when it comes time to make changes or updates to applications and their dependencies.
• Redundant coding efforts: When each application has its own API, developers have to duplicate code and effort across multiple projects. While APIs by design are a form of reusability, accessing them still involves writing code to call those APIs, validate data, etc.
• Unknown reuse opportunities: Without a clear understanding of reuse opportunities, organizations can end up investing in APIs that ultimately don’t serve much purpose. It’s common to end up with an API that exposes hundreds (if not thousands) of functions, but rarely all of those functions are used.
• Administrative overload: APIs must be secured and managed, requiring ongoing overhead to ensure compliance. When the goal is to expose a function for access by other internal developers, the process is more complex than just writing the API and publishing it.
• Not suitable for API: Not everything can or should be exposed as an API – direct connections to databases, legacy systems like AS400, or internal customer applications. Developers are then faced with the difficult task of transforming these challenging systems into reusable functions without publishing them as an API.

Introducing Capsules, a new way to approach internal reuse

At Digibee, we believe there is a better way. Our innovative approach to internal reuse is based on the concept of “Capsules ” — libraries of reusable code, essentially functions, that can be accessed from any workflow.

The benefits of Capsules

By transforming workflows into reusable code libraries, you can:

Avoid tight coupling

• Breaking the API Monolith and develop individual functions independently, without the need for the full API lifecycle
• Remove the risk of problems cascading to downstream dependencies when changes are made
• Gain flexibility to publish changes to workflows automatically or explicitly

Eliminate redundant coding efforts

• Reduce the need for duplicate code and effort across multiple projects
• Easily drag-and-drop with Capsules as reusable functions, with simple input forms and built-in validation
• Eliminate the need for code to call them or check the data they return

Avoid unknown reuse opportunities

• Use Capsules in any workflow built in Digibee
• Create useful functions that are valuable in other scenarios and publish them as Capsules for any other developer to access
• Turn any Capsule into an event-driven microservice or efficiently build APIs from a group of Capsules. Combine the flexibility of Capsules with full API capabilities when needed.

Reduce maintenance overhead

• Quickly publish and manage reusable functions for other developers to use in workflows within the platform
• Eliminate the need to manage and distribute API keys
• Only developers can access Capsules, providing a clear distinction of access

Custom “Connectors”

• Taking legacy systems like AS400, databases and custom applications and transforming them into functions
• Avoid the delay of waiting for integration vendors to support niche applications, quickly build your own connectors in the same way you would build an integration flow
• Create a collection of highly reusable functions specific to your organization/team

Traditional API-led approach

• Tight coupling between applications limits flexibility
• Duplicating code and effort across multiple projects, decreasing productivity
• Wasted investment of time and money in APIs that are rarely used
• Complex long-term maintenance and security

Digibee Reusable Capsules

• Flexibility and scalability with individual functions working independently
• Accelerate productivity with reusable code across multiple projects
• Streamline efficiency with AI-driven recommendations during development
• Simple management

The economical and flexible solution

With Capsules, you can:

• Execute workflows in an embedded manner: Start fast and grow quickly without the overhead of traditional APIs.
• Compose and decompose complete APIs: Convert full APIs to Capsules when justified by ROI.
• Event-driven execution: Run event-based Capsules, reducing costs and complexity.

Regaining Agility in Your API-Driven Architecture

By adopting a Capsule-based approach to internal reuse, you can regain the agility and flexibility essential to driving innovation and growth. With Digibee, you get both – full-featured APIs and Capsules that offer API-like reuse without the usual overhead.

While traditional API-driven approaches may seem appealing at first glance, they often lead to complexity, high costs, and limited reuse. By embracing the power of Capsules, you can simplify reuse and evolution, reduce costs, and restore agility to your API-driven architecture.
