Unlocking Business Potential with Microservices Architecture 

Microservices architecture is a style of architecture that is inspired by the way of thinking based on service orientation. The term microservice in recent searches for the term "microservices" on the Internet shows that most searches are technology-based.

Microservice architecture is used in large sites with high traffic. In this way, the main site becomes a set of small sites with separate databases that can be run on an independent server.

This article by zcoderz states that the era of popular searches such as "What is microservice?" has come to an end. Not only software vendors such as Microsoft or IBM, but content producers such as Netflix and Amazon also use microservices architecture in their products.

What Is a Microservice?

When a site's traffic increases, there is no longer a server responding to the traffic. In these cases, the first solution is to use stronger servers. But the cost of more powerful servers is increasing exponentially and there is a limit to their capacity. In the long run, the only solution is to use multiple servers to respond to users. This is where MicroServices become important.

The developer's team breaks the parts of the site that have high traffic into small sites with separate databases and places them on independent servers. For example, the file upload system in a file-selling site or the notification-sending system in a social network can be isolated and reduce a large amount of traffic on the main server.

Each of the Microservices can be implemented with a different technology, which leaves programmers free to choose the best. For example, it is possible to have a site that uses ASP, PHP, and Node at the same time, and its databases are a combination of SQL Server, NoSQL, and MongoDB.

This separation makes it possible to update one part of the site without involving other parts, and if a problem occurs in one part, the whole site will not stop working.

Using microservices has many challenges. After separating the frameworks and databases, a way to communicate between them should be created. Messenger systems are usually used, which have a complex implementation.

From another point of view, this architecture simplifies the implementation of changes in the software by implementing multiple and independent services. In this architecture, Microservices communicate with each other in two common ways, one through REST and the other through Messaging. Implementation as Messaging reduces code entanglement and minimizes dependencies between services. For this type of implementation, the MassTransit library can be used. MassTransit is a Service Bus that uses RabbitMQ and Azure ServiceBus technologies behind the scenes and helps to implement Microservice architecture more easily.

Three Key Principles of Microservice Architecture

1. Boundary Range

This term was first used by Eric Evan in his famous work called "Drive Model Design". It refers to one of the key features of microservices architecture. : Focus on business capabilities. Related features are combined into a business capability and then institutionalized and finally implemented as a service.

2. Size

 Size is a critical concept for microservices and brings us major benefits related to service maintainability and development. The ideal use of microservices architecture is that if a service is too large, it should be refined into two or more smaller services. Thus maintaining granularity and maintenance is focused on providing only a single business capability.

3. Independence

 This concept indicates loose connection and high coherence in microservices in such a way that each service in the architecture of microservices is practically independent from the other and the only way to communicate services is through published interfaces.

Advantages of Microservices Architecture

The microservices architecture's distinct component structure offers many benefits. Microservices can be helpful in this regard, as infrastructure automation is the foundation of many software products developed today. You should be aware of the following benefits of microservices architecture:

• Agility

Agility microservices can be used to establish smaller, self-governing units that manage their operations. Staff can operate more independently and productively in a specific and constrained environment. The effectiveness and operation of other development teams and components are not a concern for them. Cycle times for development are shortened. The company's overall productivity may rise as a result.

• Adaptive Scalability

Each activity can grow independently to satisfy the needs of the program it serves because of microservices. This makes it possible for development teams to estimate the cost of a product, scale infrastructure automation requirements properly, and guarantee service availability as demand grows. It is more common for businesses to need to increase a single product unit than the complete line. This procedure is made much simpler by the microservices architecture.

• Simple Deployment

Microservices enable seamless integration between deployment and business, facilitating the testing of new concepts and allowing for easy scaling if something goes wrong. Code upgrades are made easier and innovation is encouraged by the low cost of failure. Being ahead of the competition can only be achieved through innovation, and microservices architecture facilitates this.

• Technical Independence

Microservices architecture does not adhere to the one-size-fits-all philosophy. Teams can choose the ideal solution to solve their specific problems. The same model or tool may only work for some of the components, and based on their needs, they can choose the ones they want. In this way, each module and, in turn, each team working on it is technically independent.

• Reusable code

Teams can use code in a wide range of ways when it is divided into well-defined, manageable components. One feature may have its roots in a service developed with a particular use in mind. Because of this, developers don't have to start from scratch when adding new features to an application. Writing identical code over and over again is the alternative, which is tedious and redundant for developers.

• Resilience

Errors and wrong choices may inevitably arise in complex software systems. If a single drive fails and the system has to be shut down, that is unproductive. The independence of the service boosts a system's capacity to deal with setbacks. Because of its monolithic architecture, a single component failure can bring down the entire application. Microservice-based applications decrease capacity in the event of a complete service failure as opposed to collapsing. The remaining modules can keep operating normally; only the malfunctioning component needs to be fixed.

To Wrap Things Up

It is advisable to start simple if you are unfamiliar with the microservices architecture framework. Begin your project by implementing one or two modules. You can gradually scale with experience and time. If you already have a simple monolithic system in place, this method will be slightly simpler.

We now know what microservice architecture is and all of its benefits. A monolithic architectural style cannot function in modern applications without causing issues. The microservices architecture is a far superior option than its competitor, despite some of its complexities. Applications written in software can grow and become more creative thanks to microservices architecture.
