Microservices are a popular method of software development that allows for independent, connected services to work together without disrupting overall workflow. This approach is favored for its ability to improve performance, accuracy, and productivity, and can be analyzed using specialized tools for insights on performance and service levels. By using microservices, teams are able to work on individual services without affecting the entire project, a benefit not possible with other architectural styles. In this guide, learn about the basics of microservices, how they function, and the benefits they can offer your team.
What Are Microservices?
Microservices are a software development architectural style that structures applications as a collection of loosely connected services, making it easier for developers to build and scale apps. This approach differs from the traditional monolithic style, which treats software development as a single unit. With microservices, software development is broken down into smaller, independent “chunks” where each chunk executes a specific service or function. This method utilizes integration, API management, and cloud deployment technologies to allow for quick expansion as user needs and requirements evolve. The need for microservices has grown as applications become larger and more complex, requiring a new approach to development.

Microservices in the Cloud (AWS and Azure)
Microservices and cloud environments are closely connected, with the cloud being an essential part of the microservices architecture. Developers use Docker containers to package and deploy microservices in private and hybrid cloud environments, which provides benefits such as:
- Access to microservices from a single cloud location
- Ability to make back-end changes to microservices through the cloud without affecting other microservices
- If one microservice fails, the rest of the app remains unaffected
- Ability to create and scale microservices from any location
Microservices in the Cloud (AWS and Azure)
There are various platforms that automate many of the processes involved in using microservices in the cloud. However, there are two platforms in particular that developers should consider:
AWS provides tools and services that enable developers to build and deploy microservices in the cloud. These tools include API Gateway, which allows developers to create, manage, and monitor APIs; Lambda, a serverless computing platform that lets developers execute code without the need to worry about infrastructure; and CloudFormation, a service that helps developers automate the creation and management of AWS resources. By using these and other tools, developers can create highly scalable and reliable applications for their clients.
Microsoft Azure is a cloud-based platform that offers tools and services for developers to create, deploy, and manage microservices. One key feature of Azure is the ability to use circuit breaking patterns to improve the reliability and security of individual microservices, rather than attempting to address these issues at the level of the entire application. Azure also offers API management for both internal and external use, as well as capabilities for authentication, throttling, monitoring, and caching management. These features make Azure a valuable tool for teams looking to improve their agile software development processes using microservices.
Microservices in e-Commerce
Microservices have been a game-changer for retailers who used to rely on monolithic architecture for their apps. The monolithic method had several drawbacks: it took a long time to make changes to the underlying code and front-end platforms, resulting in unstable systems; services were dependent on one another, making it difficult to separate them; and making changes to the application required a large number of developers, leading to high costs.
Microservices have helped retailers by allowing them to use separate services for different tasks such as billing, accounts, merchandising, marketing, and campaign management. This approach allows for more integrations and fewer problems. For example, if there is an issue with the payment provider, it can be debugged without affecting other services like marketing and merchandising. API-based services allow microservices to communicate with each other while still functioning independently. This simpler approach has been a benefit to retailers across various niches.
Microservices in software development work in a similar way. Each service is responsible for a specific task or function, and they work together towards the common goal of creating a successful application. However, if one service experiences an issue, it should not affect the overall performance of the application. This level of independence allows developers to work on individual services without disrupting the rest of the application.
Did you know the cloud microservices market is projected to hit worth $21.67 billion by 2030 at a 18.6% CAGR.
How Are Microservices Built?
Microservices are built using a variety of tools and technologies. Here are some common steps in the process:
- Identify the functions or services that can be separated into microservices: This involves breaking down a monolithic application into smaller, independent services that can be developed and deployed independently.
- Design the microservices architecture: This involves creating a high-level design of the microservices and how they will interact with each other and other systems.
- Develop the microservices: This involves writing the code for each microservice using a programming language and framework suitable for the specific service.
- Test the microservices: This involves testing each microservice individually and also testing how they work together as a system.
- Deploy the microservices: This involves deploying the microservices to a suitable runtime environment, such as a cloud platform or container orchestration system.
- Monitor and maintain the microservices: This involves monitoring the performance and availability of the microservices and performing maintenance and updates as needed.
What are different approach to Microservices Development?
Microservices can be built in various ways, depending on the needs and preferences of the development team. Some common approaches include:
- API-driven: This method involves breaking down monolithic applications into smaller, independent services that communicate with each other via APIs.
- Event-driven: This approach involves creating microservices that are triggered by events, such as user actions or changes in data.
- Data streaming: In this method, microservices are designed to process data streams in real-time, allowing for fast and efficient data processing.
- Containerization: This approach involves packaging microservices and their dependencies into containers, which can be easily deployed and scaled in different environments.
- Cloud deployment: Microservices can also be deployed in the cloud, allowing for easy scalability and accessibility from anywhere.
Regardless of the approach taken, it is important for development teams to carefully plan and design their microservices architecture to ensure that it meets the needs of the business and the end-users.
How Do You Monitor Microservices?
To monitor microservices, developers can use a variety of tools and methods, including the following:
- Application Performance Monitoring (APM) tools: These tools track the performance of individual microservices and provide insights into how they are functioning. They can identify issues such as latency, errors, and bottlenecks in the microservices architecture.
- Logging and tracing tools: These tools allow developers to track the flow of requests through the microservices architecture and identify any issues that may be occurring.
- Service Mesh: A service mesh is a layer of infrastructure that sits between the microservices and the network. It allows developers to monitor and control communication between the microservices, providing visibility into the interactions between them.
- Custom monitoring solutions: Developers can also build their own custom monitoring solutions using a combination of tools and methods that are specific to their microservices architecture. This can involve creating custom dashboards or using APIs to extract data from the microservices.
The Future of Microservices
Serverless architecture is a way to build and run applications and services without having to worry about infrastructure. This means that developers can focus on writing code and building features without the need to manage servers or infrastructure. Amazon Web Services (AWS) offers a platform called Lambda which enables developers to utilize serverless architecture and run their microservices without having to worry about any infrastructure management.
Platform as a Service (PaaS) is a cloud-based development platform that combines microservices with monitoring. This allows developers to deploy applications and manage the architecture in a centralized way, streamlining the process and improving efficiency. PaaS has the potential to further automate processes for development teams and enhance the effectiveness of microservices.
Microservices can be deployed in multiple cloud environments, which offers enhanced capabilities to development teams. For example, microservices related to database management may benefit from being deployed in Oracle’s cloud environment, while other microservices may use Amazon S3 for additional storage and archiving. This approach also allows for the integration of AI-based features and analytics from Azure across the application.
What Are the Benefits of Microservices? Why Do They Exist Today?
