The Role of Microservices Architecture in Mobile App Development

Ever wondered what users expect from a mobile app development business? Your user would prefer a fast-performing and high-quality application that exceeds their experience expectations. Additionally, they would love it if your website doesn’t crash too often.

The design elements, codebase and testing are pivotal to ensure high-quality solutions. However, the most crucial aspect of performance optimization is the architecture. A well-structured skeleton can help you plan your experience design and encourage quality.

Microservices architecture has been gaining a lot of attention in recent times. Several businesses have bolstered their online reputation and mastered performance with this architecture.

This architecture breaks down app development into smaller chunks that shorten the development cycles. Each of these apps extends an independent business service that fosters organic growth.

You can use this architecture to simplify workflows and build a profitable business. This article will explore the microservices architecture in-depth to understand its pros, cons and use cases.

What is Microservices Architecture?

Microservices Architecture

Microservices architecture looks at the mobile application as a series of small and independent solutions. These independent solutions can solve a particular problem and become an extension of the business service. Moreover, these independent services can be coupled into a single system or enjoyed independently by the user.

This software development approach allows businesses to release their apps faster into the market. It helps the business offer its services in a more manageable and approachable manner to the user.

How Microservices Architecture Works?

The Microservices architecture undergoes a proper process, where each part of the process looks into specifics.

  1. Decomposition- This is the part where a large monolithic application is broken down into several small services. As they are self-contained, your users can use it as an independent application that serves a particular business function.
  2. You can use APIs to enable communication between these different services or systems. These services can also be used independently by the users or businesses.
  3. You can also use different programming languages or frameworks to build these services as they are developed and scaled independently of the others.
  4. The geographical boundaries are blurred in microservices. You can use servers and data centres across geographies for better access and zero downtime.
  5. Lastly, it promotes agile development as teams work on separate development or services.

The perfect example of a microservices architecture occurs when you consider an eCommerce solution. Microservices architecture builds separate eCommerce solutions for services like user management, product catalogue, order processing and payments.

These can be developed and scaled independently. At the same time, you can integrate them into a single app structure.

Top Benefits of Microservices Architecture

  • You can scale a particular system or service independently without impacting the other solutions.
  • It extends the flexibility to use different tech stacks and tools to build individual services for your business app.
  • As the teams are spread out to work on independent solutions, you can shorten development cycles. It also promotes agility, which encourages fast releases for your business.
  • Each service has a separate codebase. It is easier to maintain and update the smaller codebases, reducing resource efforts.
  • You can identify the faults or issues within the systems owing to the independent systems. It is easier to isolate the bugs and address them with this architecture.
  • Your teams can work independently and collaboratively with this architecture.
  • It promotes continuous integration and deployment services for quick and fault-free app development.

Monolithic vs Microservices Architecture

You must be aware of the major differences between a monolithic and microservices architecture to make the right choice. We will consider the top five factors to understand the difference.

#1 Definition

  • When an application is developed as a single and integrated unit, it is a monolithic architecture. The user interface, logic and data access layers are tightly integrated into this application.
  • Microservices architecture tends to break down the entire application into small and independent services. Each service is responsible for a specific aspect of the business. You can use APIs to connect the services and integrate the systems.

#2 Development and Deployment

  • In monolithic architecture, developers work with a single codebase and employ the unified deployment method. After changing a small portion of the application, the developers need to deploy the entire application. It uses a systematic development approach. However, the development process is slower.
  • Each service is developed and deployed independently with Microservices architecture. Each service has individual codebases and logic. You can roll out updates and add features to these independent applications. It ensures greater flexibility. However, you need to manage the interdependencies carefully for the best outcomes.

#3 Scalability

  • You must replicate the entire application to scale your monolith solution. This can be a resource-intensive and time-consuming affair. Moreover, you need to scale the budget and resources according to the complexity of the update or feature addition.
  • You can foster granular scalability by implementing microservices architecture. Each service can be scaled independently and as per the business need. It helps manage the resources available. Moreover, your resources can ensure optimal resource utilization to fulfill the job.

#4 Maintenance

  • It is easier to maintain a monolith application owing to the single codebase. But, as you add more features and upgrades, your app grows complex. Handling the complex workflow and maintaining the app can be slightly challenging
  • Microservices architecture is distributed. As a result, you must maintain an individual codebase. This is easier to handle. However, you must employ the best versioning and communication protocols to coordinate these changes.

#5 Fault Tolerance

  • If a component or unit of the monolith application fails, it can lead to an app failure. The app becomes unavailable to the users. You must ensure proper redundancy and failover mechanisms for fault tolerance. This must be applicable throughout the application
  • The microservices architecture is inherently fault tolerant. If one service fails, the others remain unaffected. You need to apply redundancy or resilience for the particular service only.

How to Make the Right Choice?

It is indeed a challenge to choose between the monolithic and microservices architecture. Here are a few factors to consider before making the right decision.

  1. If you are working on small-scale projects, you can opt for monolithic architecture. It is best for solutions that don’t need scaling or large-scale maintenance. You can choose microservices for scalable and large-size projects that delve into complexities.
  2. Monolithic architecture is best suited if you have a team that is well-versed in traditional development. They may not understand the nuances of distributed systems and cannot offer the solution. however, if you have a team that can build, manage and maintain distributed systems, go with microservices architecture. They should be adept with containerization and orchestration.
  3. Monolithic architecture is suited when you need consistency throughout the application. You can use the architecture when you need a predictable application scaling. Microservices architecture fits your needs when you have diverse scalability needs. Moreover, it is a great asset when you have limited scaling and distributed scaling aspects.
  4. If your project poses stable and defined requirements, you can go with a monolithic architecture. However, if you need to update your application frequently, you might want to choose microservices. It can help with agile development and independent service deployment.
  5. If you have developed a resource-intensive solution and looking for optimal resource utilisation, go with monolith. It can reduce resource overheads as you don’t need to manage multiple unique services. Microservices are resource-optimized and can handle fluctuating resource demands. You can easily use this architecture for best resource allocation.

Microservices vs Serverless Architecture

Serverless architecture is a new and emerging trend. You must know how it differs from microservices.

Microservices Architecture

  • Microservices architecture is when you develop an application as a collection of services that are independent and loosely integrated.
  • Each service operates independently. This ensures autonomy in development-to-scaling cycles.
  • This architecture supports continuous deployment, which leads to short release cycles and agile development.
  • Each service is independently scaled to meet the optimization and resource utilization needs.
  • Microservices are flexible and adaptable. However, they need complex orchestration to manage the distribution.

Serverless Architecture

  • Function-as-a-service architecture allows you to write the functions without managing the infrastructure.
  • The functions are event-triggered in serverless. Specific requests or events can lead to a particular function. This leads to resource optimization.
  • You can scale the functions to meet the workload fluctuations with serverless.
  • As developers don’t need to maintain or manage the servers, they can focus on coding jobs. This improves the efficiency.
  • This architecture might cause latency as the resource initialization occurs only when a function is requested. This is particularly true after a short period of inactivity.
