What is Microservices in Mobile App Development?

Camunda, in association with Researchscape, has surveyed 354 enterprises to find who are ready to implement a microservices architecture. And you will be shocked to know that research showed that 63% of enterprises are now implementing microservices architectures.

The most cited reasons for implementing a microservices architecture are as follows:

  • Improved employee efficiency
  • Improved customer/end-user experience
  • Cost savings on infrastructure and other development tools

Despite the growing popularity of microservices, several entrepreneurs are unaware of the impact of microservices in mobile app development to scale their businesses and boost sales.

Therefore, being a leading mobile app development company, we have decided to curate this guide that helps leading startups and entrepreneurs understand microservices and their impact on revenue-generating businesses.

What are Microservices?

Microservices is an architectural innovation that mobile app developers use to create individual components for enterprise-grade applications.

The aim is to merge the separate parts to execute a single outcome. Each microservice performs a specific task. That means you do not have to upload the entire codebase in a single repository unit, unlike traditional monolithic architecture.

All the microservices are independent of each other so that each microservice is independently deployed, tweaked, and redeployed without compromising the quality of the application. This also facilitates rapid deployment to make the mobile app development process efficient.

Here is the image that represents how a monolithic approach and a microservice architecture function.

As of today, big giants like Amazon, Netflix, Uber, and LinkedIn are using the microservice architecture. So now, let’s check when you can implement microservices in your app development project.

When to Opt for Microservices Architecture Development?

Even though microservices offer quite a flexibility to developers to build complex apps, with this approach, developers are able to implement changes in real time. In fact, research conducted by Statista reported that 37% of respondents are using microservices partially.

However, there are a few conditions when it is best to use this technique to yield high benefits.

Conditions when it is best to opt for microservices architecture are mentioned as follows.

  • You want to develop a mobile app from scratch.
  • You want to rebuild your existing legacy app.
  • You want to add a new feature or functionality to an existing app.
  • You want to add more storage for the database to accommodate bulk app features and services.

Now talking about how you implement microservices successfully, let’s check all the steps that you can follow.

How to Implement Microservices in Mobile App Development in 10 Steps

If you are curious to know how to adopt the microservice approach for your Android or iPhone app development, then here is the step-by-step process that you should consider for yielding optimum results.

Step 1: Before you actually jump into implementing this approach, you need to decide whether you want to develop an app by leveraging this architecture or not.

Step 2: If you agree to implement this approach, analyze your existing infrastructure. And if you are building a new mobile app from scratch, then identify the features you want to integrate into your app.

Step 3: Next, you will be required to set up an app development team with experience implementing this architecture. Also, you can interview the developers to check whether they have an understanding of the roles and responsibilities or not.

Step 4: Decide on the tech stack, including suitable app development languages for iOS and Android and their framework.

Step 5: The developers will set up the base architecture for your application that involves containers, virtual machine templates, and services.

Step 6: The API gateway needs to be implemented further as it is the main entry point for app users.

Step 7: In the next step, the team will deploy the most common and non-functional requirements at the Gateway level.

Step 8: The developers will further need to monitor and map the monitoring for the app.

Step 9: Finally, once the app is completed, perform various automation testing to ensure that the app is 100% bug-free and running smoothly on the architecture.

Step 10: Lastly, make changes if you find any issues. If not, then launch the app.

These are the 10 steps you need to follow to implement a microservices architecture successfully. Now, if you want to know the benefits of microservices in app development, then check the next section.

4 Benefits of Using Microservices in Mobile App Development

Microservices architecture is a combination of discrete parts that make the app easier to build, text, and maintain. However, there are other significant advantages of using microservices. Let’s uncover these benefits in this section.

  1. Increase Productivity and Agility by Reducing the Writing of Codebases

  2. As each component of microservices functions differently and is independent of each other, app developers have the freedom to choose various programming languages and frameworks of their choice.

    Also, microservice reduces the requirement for writing additional codebases, ultimately helping developers enhance their productivity level. It is easy to maintain the app as it is broken down into manageable mobile app development services.

    This way, developers are not dependent on each other and don’t have to wait unnecessarily to finish their work and start another task. Ultimately, this helps developers boost productivity and launch the app in the market faster.

  3. Microservices Make It Easy to Deploy the App

  4. If you implement the microservices architecture, then you write, test, and deploy the app at the same time by getting regular feedback on the mobile app development process.

    As the development team follows a continuous delivery model to handle the mobile app development life cycle, every project member collaborates to deploy the app smoothly.

    So even if the team works on developing a single application, microservices will let you collaborate with the team better and don’t hamper the deployment process.

  5. Microservices Require Low Maintenance

  6. Each module of the microservice architecture has its own database to store data. Therefore, the modules utilize different underlying resources, which becomes more convenient to reduce the risk of introducing bugs in the mobile application.

    Small units with different functionalities are easy to debug and maintain. Hence, if you have implemented microservices in your app, then it takes less time for you to maintain the app and implement changes whenever required.

    With this, you can also save app maintenance costs and additional resources. In addition, your existing team would be able to fix the errors easily without affecting the performance of the app.

  7. Microservices Help in Improving Fault Isolation

  8. If you know the traditional monolithic architecture, then you must know that if one component fails, then it leads to bringing down the complete application.

    Suppose a gaming app is built on monolithic architecture, so if the specific component of the app starts to crash down, the entire user experience of the app becomes faulty and flawed.

    However, if you implement microservices architecture, then it is easy for the developers to identify the exact issues. Even if one or more components are affected, the developer can quickly resolve the issues without compromising the performance of other components.

    Also, this helps you cut down on app development costs, maintain the quality of the application, and ensure that the cross-functional teams are able to carry out their tasks without facing any challenges.
