Key Microservices Design Patterns for Mobile
Over the years, the mobile application development ecosystem has expanded significantly. As
the desire to have a scalable, maintainable, and flexible architecture continues to grow, a
number of developers and mobile application development companies have begun working
with microservices. These allow teams to create modular apps which are easier to scale and
faster to update, thus making them extremely useful in iPhone apps development and Android
apps development. However, it is important to understand the relevant microservices design
patterns that one needs to adopt when developing a mobile app. This article outlines the main
microservices design patterns which can be used in mobile app development architecture
including how they aid in the improvement of the development process, performance, and user
experience.

What are Microservices?
Before going into design patterns, it is important to answer, what are microservices? This is an
architectural style that structures an application as a collection of small services developed
independently and deployed together. Services are designed with a specific business activity in
mind and can be scaled, deployed, or built in isolation. This is in contrast to a monolithic
architecture, where the entire application is linked and incorporated into a single unit.
Mobile applications are now being developed with microservices architecture because it offers
more versatility, enhanced scalability, and easier component management of the application.
Similarly, mobile application development companies find microservices design patterns to be
beneficial as they enable the faster delivery of fully functional and high performing robust
applications.
Now, what are the Advantages ‘Microservices’ would give Mobile Developers?
Microservices are advantageous for mobile app development with respect to for both iPhone
and Android.
These include:
Scalability: Microservices enable horizontal scaling of application components. Mobile app
development agencies can scale individual services instead of the entire app as the user base
increases.
Fault Isolation: If the app’s functions are broken down into independent services, a failure of
one service will not affect the others. This increases the reliability of the app.
Faster Development: Parallel development is facilitated by microservices as different services
can be worked on simultaneously by different teams faster reducing the overall development
time.

Better Maintainability: Microservices architecture allows development teams to concentrate on
specific components of the app, which leads to better code quality and makes debugging,
testing, and maintenance easier.
Crucial Microservices Design Patterns You Should Apply On Your Mobile App Development
Project
Let us focus now on the main microservices design patterns that a mobile app development
company can apply when developing efficient and scalable mobile applications.
1. API Gateway Pattern:
The API Gateway pattern is one of the most essential for any mobile application that is built
using microservices architecture. An API Gateway has a single access point for mobile apps to
use to reach all backend services. This pattern helps provide separation between mobile apps
and microservices and has several benefits such as:
Consolidated Resource Access: Instead of having the mobile application to call multiple
microservices, the mobile application communicates with the API Gateway.
Easier Mobile Application Development: Mobile application developers manage only one
connection to the API Gateway and not to each microservice.
Enhanced Security and Performance Control: The API Gateway is capable of enforcing certain
controls such as authentication, authorization, and rate limiting, hence improves security and
performance.
This pattern works especially well for mobile app development companies focusing on Android
app development or iPhone app development because they will be able to pass their clients a
functional product without worrying about the inner structure of the backend.
2. Database per Service Pattern:
Within the microservices system, each service is assumed to use their own respective database
that falls under the Database per Service pattern. This type of architecture is more crucial in
mobile app development because mobile applications tend to work with a lot of data that need
to be accessed or changed regularly.

Independent Data Management: A microservice architecture allows each service to own their
own database, which ensures that one service’s data will not interfere with other services.
Data Consistency: A mobile app developer can use eventual consistency, which means that
every service must be enabled to modify its data without having to rely on the real time
consistency of other services.
In relation to mobile apps development, this architecture pattern leads to more efficient
management of data and enables mobile applications to scale without suffering from
performance issues.
3. Event-Driven Architecture Pattern:
As a rule of thumb in mobile app development, responsiveness for a thorough user experience
is key as interactivity is one of the features mobile solutions provide. The Event-Driven
Architecture pattern allows microservices to interact with one another via events
asynchronously. Instead of having each service to service communication, one service can
publish an event and other services can subscribe to it. Loose Coupling: Guaranteeing changes
in one service will not directly impact other services or components. This pattern provides a
significant advantage when dealing with real-time data, which is very much needed in modern
mobile applications including messaging and social media. In an iPhone or Android app
development company, the use of an event-driven architecture improves the application
performance in an event-driven model, especially for applications where real time notifications
or updates are required.
4. Circuit Breaker Pattern:
The Circuit Breaker Pattern stops the failure of an entire system as a result of a single system
failure. In a microservices environment, when a single service goes down, it is capable of
bringing the rest of the system down too. The Circuit Breaker pattern monitors the calls of a
particular micro service and if the service is under a threat, it stops the calling until the service
issue is resolved. Fault Tolerance: Mobile applications, for instance, need to ensure that these
applications do not stop functioning just because certain microservices are not available.
Improved User Experience: Users using the iPhone and the Android apps do not have to face
the frustration of non-functioning applications during service interruptions. For a mobile app
development company, it is a must to apply the Circuit Breaker pattern so as to improve the
robustness of their mobile applications and their usability.

5. Service Discovery Pattern:
Within a microservices structure, services should be able to locate each other and have the
ability to communicate. The Service Discovery pattern enables this by having a service registry
that tracks all services so that they can be easily scouted and communicated with. Dynamic
Service Interaction: It is easy to add or remove services without the system being manually
reconfigured. Reduced Configuration Complexity: Developers won’t need to set the addresses of
the services in the system. In the case of a mobile application development company, Service
Discovery makes it impossible to hardcode mobile services into specific endpoints which makes
it easier to maintain the services especially when the application grows in size.
Conclusion:
From my perspective, the growing complexity of mobile applications necessitates a careful
selection of architecture to ensure scalability, maintainability, and resilience. The development
of microservices offers several advantages in the creation of both iPhone and Android
applications - increased scalability, higher fault tolerance, and better usability. These advantages
stem from the adoption of key microservices patterns such as the API Gateway, Database per
Service, Event Driven Architecture, Circuit Breaker, and Service Discovery. Use of these patterns
enables mobile applications to undergo rapid development, in response to both the increasing
customer base and evolving requirements. For the programmer, the development of these
patterns streamlines performance optimization and enables efficient mobile applications that
meet today’s user needs.
