How to build a successful microservice Architecture [translation]

Time:2022-7-26

As technology becomes more complex, many teams are evaluating how their architectures best support future businesses. One of these architectures, microservices, is becoming an increasingly preferred choice for forward-looking technology departments. Microservice architecture may be the key to unleashing business potential, but how to achieve it?

|What does microservice mean?

“Micro service” may sound like a popular word, but this modern organizational practice is rooted in sound and innovative software engineering.

If you are considering implementing microservices, your core goal is to split each business component into an independent service to build a complete application. These components can not only be integrated into existing applications, but also be used separately and integrated into future applications.

By definition, microservices are very different from traditional software development practices, whose goal is to bundle all content into a simple package.

|How to build a microservice architecture?

If you want to build a successful microservice architecture, you must follow the following three basic steps.

Based on monomer

Before any application becomes a part of the microservice environment, it must start with a single application. Each application is simple at the beginning, but with the continuous collection of feedback and iteration, we have determined more key functions that need to be bundled into the application. The application becomes more and more complex, which ultimately affects the operation efficiency of the organization. This is the time to start this most critical step.

For example, if you are building an e-commerce application, the core idea is very simple: create an interface in which users can browse the catalog, add products to the shopping cart and pay, which completes the most basic shopping process.

However, you will soon find that you need to create a background page for users to query and operate. On this page, you can determine other useful functions, such as the integrated order tracking system, or even the automatic return portal, in case of inappropriate return. This is very important for your customers to give you an advantage over your competitors.

In this research stage, you can start to determine whether the application is worth decomposing into microservices, but you can only start from a single application and work outward.

Reorganize internal team

Some people may think that microservice architecture is a highly technical pursuit, but in the Internet era, the success of enterprises largely depends on the structure of internal teams and their ability to support the microservice environment. Any organization that designs a system (broadly defined) will produce a design whose structure is a copy of the organization’s communication structure.

When adopting microservices, our team also needs to optimize. If the development team includes the back-end team, the front-end team and the operation team, the mode that the front-end team and the back-end team create individual applications independently and then deliver them to the operation team for production is not helpful for a successful microservice architecture.

For internal restructuring, remind yourself to treat each service as an independent product, which means creating a small team. Every team should have the ability to develop and maintain services from beginning to end. Without this restructuring, it will be difficult to pursue microservices efficiently or sustainably in the long run.

Implement with calculation method

To ensure the success of the microservice architecture, it is essential to follow established best practices.

***Use restful API specifications to simplify the connectivity between services**

***Decompose the database to decouple your services, thereby improving uptime and security**

***Use more professional API development management and monitoring tools to create and manage microservices more efficiently and quickly**

***Adopt the “continuous delivery” model to help avoid friction in the development and test stages and shorten the delivery time**

This practice step only briefly introduces the idea. In practice, it will be found that the steps that organizations should take to build a successful microservice architecture will be affected by different factors, such as the size of the organization, the complexity of applications, and the current agile development level of the team.

|Looking for external resources

In the final analysis, building a microservice architecture is not only highly technical, but also requires changing the way in which internal projects are managed. This may make people feel that this is a difficult task, but if there are good external resources, such as appropriate microservice API development management and monitoring tools, you will be able to get many benefits of microservices as soon as possible.
