Composable Architectures

What is CA?

Composable architecture is a way of designing software that makes it easy to create reusable components. This can help developers to build applications more quickly and easily, as they can simply combine existing components to create new features. Composable architecture has been gaining popularity in recent years, as businesses look for ways to reduce the time and cost of developing new applications.

Composable architecture is like a construction set for software developers. It allows them to build different applications by combining different components. This is similar to how children can build different models with a Meccano/Building Blocks set.

The key to composable architecture is that the components are reusable. This means that developers can use the same components to build different applications. This can save time and money, and it also makes it easier to maintain and update applications.

The?Gartner Composable Business Index (the Index is defined in?Toolkit: Composable Business Index From the 2020 Gartner IT Symposium/Xpo Keynote) applies to many different facets and contexts of modern business, including its technology, organization, ecosystem, marketing strategies and business models. In each area of business the objective of increased agility is the same, but its core tenets apply differently. For example, ask yourself: What are the building blocks that support composability for organization, ecosystem, marketing strategy and business model?

Why CA?

Here are some of the benefits of composable architecture:

• Increased speed of development:?Composable architecture can help developers to build applications more quickly, as they can simply combine existing components to create new features.
• Reduced cost of development:?Composable architecture can help to reduce the cost of development, as developers can reuse existing components instead of having to create new ones from scratch.
• Increased flexibility and scalability:?Composable architecture can help to make applications more flexible and scalable, as they can be easily adapted to changes in requirements.
• Improved testability:?Composable architecture can help to improve the testability of applications, as individual components can be easily tested in isolation.

Composability

Gartner has proposed following to determine a composability index

To adopt composability, applications and software engineering leaders should:

• Understand the business needs for change.
• Consider the costs and benefits of composability.
• Assess the organization's capabilities.
• Identify signs of preparedness for composability.

Signs of preparedness for composability:

• Product-centric culture.
• Agile development practices.
• Experience with APIs.
• Experience with low-code tools.
• Multidisciplinary teams.
• Close business engagement.
