Technology is changing at a breakneck pace. People rely significantly on the internet for everyday chores ranging from shopping to banking and healthcare. This has made it necessary for service providers to meet ever-increasing consumer demand, which is accompanied by:

User requirements keep changing.
The increasingly difficult security landscape

This encourages service providers to reject monolithic software development methodologies in favor of Agile and DevOps approaches that allow them to adjust fast to changing needs.

Another trend is microservices-based architectures, in which applications are constructed as several loosely connected services. The function of microservices in the DevOps process will be discussed in this article.

Microservices Overview #

Microservices is a development architecture style that contrasts with traditional, monolithic programs (where the entire application is considered and developed as a single entity). The microservices architecture divides an application into loosely connected services.

Consider the following internet buying platform:

The whole platform, including inventory management, payments, and a shopping cart, is created as application components in the traditional development method. Any update involves the creation and deployment of a single entity.
On the other hand, Microservices design divides the application into discrete services (inventory management service, payment service, shopping cart service) that may be built and deployed independently. This method isolates any difficulties with that individual service, reducing their influence on the application.

Microservices Benefits From Monolithic Architectures #

A Fortune 100 organization, for example, collaborated with XYZ to grow its service. They created the logistics platform to optimize logistics amongst its 400+ facilities in more than 60 countries. However, after several months of application, the remedy proved ineffectual. It took a lot of work for them to add new features and scale the monolithic platform. And scaling was critical since they had a large number of factories, warehouses, and suppliers, as well as a large number of raw materials and completed items that circulated among them. Although they saw the need to shift to microservices, they needed to gain the in-house knowledge to handle many technical difficulties and make the platform more efficient and scalable.

The platform’s monolithic architecture was the primary reason it was not scalable and wasteful. Assume a Solution Architect created and delivered a new cloud-native platform architecture based on Azure Kubernetes, together with the recommended teach stack and the most efficient roadmap.

Migrating to microservices enables the seamless addition of new SaaS services such as anomaly detection, delivery prediction, route recommendations, object detection in logistics, OCR (optical character recognition) of box labels, Natural Language Processing for document verification, data mining, and sensor data processing. Hope the example explains the benefits of microservices.

Microservices’ Role in DevOps #

Consider a DevOps pipeline for constructing a microservices-based application to understand the role of microservices in DevOps better.

The first change brought about by microservices is a shift in how companies approach development. Because everything is separated into services, development teams may be dispersed to tackle each service. As a result, the development scope will be reduced while the development process will become more flexible.

Overall flexibility #

This adaptability enables DevOps teams to resolve challenges successfully. For example, if a production problem is detected, the development team may correct it in the affected service and deploy it with minimum disruption to the SDLC of other services. Furthermore, if any service demands a new feature, developers may create and deploy it in production without interfering with the development of other services. This decoupled approach simplifies development and testing while allowing services to be independently changed.

Containers #

Containerization is another feature that supports and extends microservices-based systems. Each service is packaged as a container image, which minimizes complexity while expediting the continuous delivery process.

Services can operate as fully autonomous entities, with all dependencies and requirements contained within the container. As a result, the services are system-agnostic and reusable and may interface with any other system.

APIs #

Another element that goes hand in hand with microservices is APIs. Users require a robust communication technique to communicate amongst disconnected services.

APIs allow developers to provide only the necessary endpoints and data while hardening the service and offering a globally compatible interface. This is also an issue when developing reusable system-agnostic services.

Automation #

Then there’s automation. Most testing, packaging, and deployment procedures in a microservices architecture may be automated for each service. Because each service is in its own DevOps pipeline, any problems with a single automated job have no effect on the other services. Furthermore, feedback loops become significantly shorter while fixing defects with the streamlined codebase.

The deployment and maintenance stages are when microservices shine the brightest in terms of automation. Once testing is completed, and the container image has been uploaded to a container registry, an automated step in the deployment process will be initiated to deploy the service as a container. This streamlines the deployment process by removing the requirement for specific network setups or dependency management before deployment.

Increased availability, scalability #

Finally, service containers placed in clusters and managed by an orchestration platform automatically boost the application’s availability and scalability.

If a service container fails, it may be easily replaced with a brand-new service container.
If there is a significant demand for a service, a new container might be constructed to meet the need.

This enables scale-out methods without depending on cost-prohibitive scale-up strategies based on resource increases.

Conclusion #

Microservices architecture is not a one-size-fits-all solution. Despite its decreasing popularity, a monolith provides substantial and persistent benefits that work better for many use cases.

If you have a new company concept and want to verify it, you should start with a monolith. There is no need to integrate microservices while working with a small technical team to create a basic and lightweight application. A monolithic application will be considerably easier to create, update, deploy, and test.

Microservices design is better suited to complex and dynamic applications. It provides excellent solutions for managing a complex system of many operations and services within a single application. Microservices are appropriate for systems that encompass a wide range of user experiences and workflows. However, adopting this paradigm would only be feasible with adequate microservices skills.

If your development team needs microservices skills, you can choose a software development partner who has firsthand experience designing microservices architecture. Many successful IT organizations now outsource microservices development to overseas IT suppliers.
