Microservices and Refactoring Code

Code refactoring enhances microservices 

One of the more important coding disciplines in object-oriented programming and SOA is code refactoring. The techniques allow developers to restructure code as they better understand usage considerations, performance factors, or technical debt issues.

Refactoring is a key technique for transforming monolithic applications into microservices. Refactoring strategies include separating the presentation layer, extracting business services, and refactoring databases.

8 steps to achieving the ‘cloud everywhere’ vision

If you were to imagine the perfect book to describe IT organizations right now, it might be entitled A Tale of Two Clouds.


Refactoring should focus on reducing dependencies.  Refactoring also improves microservices in important ways, such as:

Obviously, firms cannot rewrite all code bases.  You can’t just rewrite everything—you need to phase the transition. One best practice is to set clear service-level objectives that are implementation agnostic and manage the user’s impression of your service even as you are transitioning to cloud-native implementations.

Embrace microservice design patterns

Design patterns have always been used as tools to structure code around common problem sets. For example, categories of object-oriented design patterns are creational, behavioural, and structural; they’re used to solve common problems in software design. SOA design patterns have been around for more than a decade and are a precursor to today’s REST API and cloud API design patterns.

Using microservice design patterns is critical for long-term success. Technology organizations target independent, resilient, auto-provisioning services that support failure isolation, continuous delivery, and a decentralized governance model. That can be challenging if development teams don’t have a common language, microservice architecture, and implementation strategy to develop with design patterns.

Many architects suggest that using the composite microservice design pattern enables developers to focus on the user experience. This design pattern is particularly important when developers build applications connected to multi-cloud services and SaaS platform APIs.  A composite pattern is a collection of endpoints presented through an abstracted view. Developers can go to a service catalogue, make calls to a composite, and they should not care about what goes on underneath.

Building a Better Workstation Platform: 5 Reasons to Upgrade

Creating cloud-native applications and microservices requires development teams to excel at longstanding software development practices such as collaboration, code refactoring, and developing reusable and reliable services. Since teams are developing these services at a significant scale, it’s important to learn, adapt, and mature these best practices.
