The world of technology is full of constantly changing and developing dynamics. Software development processes are shaped in line with these dynamics and new approaches emerge. In this context, microservice architecture has become one of the most popular and effective software architectures today. The advantages it offers, especially for businesses developing large-scale applications, have made it a preferred option. Knowing how microservices architecture works and in which situations it provides better results is critical for software developers and administrators.

In a meeting we had with a customer last week, the issue of how important microservice architecture is for the future of their projects came to the agenda. Our customer stated that if they adopted this new approach, they would have a more efficient and flexible software development process. At this point today, this is a situation that many software developers and managers frequently encounter. The advantages and application scenarios of microservices architecture in software development provide important clues to understand why this approach has become so popular. In this article, starting from the definition of microservice architecture, we will look at its basic features, advantages, usage scenarios and how it works in detail.

What is Microservices Architecture?

Microservices architecture is a style of software development that aims to break down large software applications into smaller, independent, functional units. This approach involves designing each function or feature of an application as a separate microservice. Each microservice focuses on a specific business area and can run independently. Microservices often communicate through RESTful APIs (Representational State Transfer Application Program Interfaces), allowing interaction between different components of the application. This structure increases the flexibility of the application and also allows it to be developed faster with fewer dependencies.

Microservices architecture was developed to overcome the limitations of monolithic architecture (monolithic structure). In traditional monolithic architecture, all components of an application are gathered under a single structure. This causes all parts of the application to be interdependent, creating serious problems with changes, maintenance, and scalability. Microservices, on the other hand, allow each component to be updated, deployed and scaled independently. This adds flexibility and speed to the software development process.

Key Features and Benefits

• Independent Development and Deployment: Microservices allow each component to be developed and deployed independently. In this way, different teams can work on different parts of the projects at the same time, thus speeding up the development process.
• Flexibility: Thanks to the microservice architecture, different parts of the application can be changed and updated flexibly. This allows the continuous integration (CI) and continuous deployment (CD) processes of software to become more efficient. For example, a bug in a microservice can be fixed without affecting the entire application.
• Scalability: Each microservice can be scaled independently based on its needs. For example, when an application’s payment processing becomes congested, only the payment microservice can be scaled, thus improving the application’s performance in high-traffic situations.
• Technological Diversity: Microservice architecture allows the combination of different programming languages ​​and technologies. In this way, each microservice can be developed in its own optimum environment and benefit from the advantages of different technologies.
• Fault Isolation: Microservices minimize the impact of other services in the event of a service failure. This increases the overall reliability of the application and prevents situations that negatively impact the user experience.
• Compatibility with Business Processes: Microservice architecture provides a structure that is more suitable for business processes. By focusing on specific business areas, operations can be managed more efficiently and business processes can be better optimized.

Usage Scenarios

Microservices architecture provides an effective solution in many different scenarios. These scenarios include:

The majority of our customers prefer this solution.

• Major Media Platforms: Major media content providers like Netflix can instantly process billions of API requests thanks to their microservice architectures. This structure allows users to access content quickly and without interruption. For example, when platform users are watching content from different devices simultaneously, microservices can quickly respond to these requests.
• E-commerce Sites: E-commerce platforms such as Amazon have improved user experience by using microservices architecture. For example, different functions such as payment processing, product listing, and user registration are handled by independent microservices. This way, updates to one section can be made without affecting other sections.
• Financial Applications: Banks and other financial institutions say they leverage microservices architecture because they process high volumes of transactions. In this way, transactions are processed faster and the security of the systems is increased. For example, loan applications made through a microservice can work integrated with the database in a separate microservice.
• Web Migration Processes: When websites need to be moved or renewed, microservice architecture ensures that this process goes smoothly and without interruption. Independent operation of key components minimizes disruptions during migration. This provides a seamless experience for users.

How Does It Work?

Microservices architecture works by separating an application into different components based on their functions. While these components work together as part of the overall application structure, they are also independent within themselves. Each microservice focuses on a specific business process and communicates with other microservices via API. This structure allows different components of the application to come together and interact.

So how?

To understand how a microservice works behind the scenes, it’s important to look at how customer requests are processed. When clients create requests through the user interface, these requests are directed to the relevant microservices through the API gateway. The relevant microservice processes the requests and returns the required data, and this process is instantly presented to the user. This structure allows each component of the application to operate independently and improves application performance.

You may ask why it is so popular?

Who Should Use It?

Microservices architecture is especially suitable for software companies, technology startups, and e-commerce platforms that develop large and complex applications. This architecture is ideal for supporting continuous integration and deployment processes in projects that require rapid change. It also offers an important option for businesses that want to overcome the limitations of traditional monolithic architecture. Additionally, financial institutions and media platforms that require large data processing capacity can also benefit from microservices architecture.

Balance of Performance and Security

As network security increases, performance decreases — this is an old myth. In a properly designed network, both are possible. The problem is that security devices become bottlenecks. Next-gen firewalls can inspect traffic at wire-speed with hardware acceleration.

SD-WAN technology optimizes the internet access of branch offices. We have customers who reduce costs by 60% by using broadband instead of MPLS. Moreover, thanks to application-based routing, critical traffic always gets priority.

Restricting lateral movement within the network with micro-segmentation is a must for modern security architecture. Even if the attacker infiltrates a point, his movement space is minimized.

Frequently Asked Questions

Should we switch to SD-WAN?

If you have 3+ branches and MPLS costs are high, yes. SD-WAN establishes a VPN-like secure connection using your existing internet lines. Application-based traffic routing ensures the performance of critical business applications.

Why is network segmentation important?

In a flat network structure, leakage at one point spreads to the entire system. You narrow the attack surface by segmenting with VLAN and micro segmentation. Regulations such as PCI DSS also require this.
