Advantages and Disadvantages of Microservices Architecture

Companies have to respond more quickly than ever to consumer demands and changing conditions in today's business environment. Software systems must be simple to implement, easy to maintain, and still available to keep up. Even though traditional architecture can still do a lot of this, there is a limit. At some point, for the future of the organization, a more dynamic and flexible approach to application growth is crucial.

One such approach is microservice architecture. Microservices deliver quicker and easier software adjustments compared to traditional monolithic architectures through the modularization of complex systems. Developers then compose applications from the resulting interchangeable, upgradeable, and scalable components. In an ideal world, this modular architectural style accelerates business growth by facilitating the agile implementation of innovative features. However, decomposing applications can also add complexity to a monolithic model.

Microservices: General Characteristics

Microservices, or architecture of microservices, are software organized or configured as a set of services that are loosely connected. Microservices have these characteristics in general:

• Every microservice has a data model of its own and manages its data.
• Using "dumb pipes" such as an event broker and/or a lightweight protocol like REST, data moves between microservices.
• Small reach that requires a single business feature piece
• Internal operations are a "black box" accessible only through the API for external programs.
• The functionality of its software: It can be broken down into many individual components. To achieve this, without affecting other functional aspects of the application, each of the services can be deployed and updated.
• Characteristics of their organization: The way they are structured suggests a contrast with the monolithic world, as factors such as the capacities, requirements, and desires of the company or customer where they are to be applied are taken into account. Multi-purpose modules are used for architecture, achieving the development of a standard module for all, providing a particular service. Undoubtedly, time savings and convenience in maintenance activities are the greatest gain, ensuring that the majority of the team can complete their workday while maintaining a module.
• Architecture characteristics: each module is independent and each module has its database; in other words, not all services are linked to the same database. Overloading and server downtime are thus avoided.
• Characteristics of their alerts and actions: When many services are transmitted, in the event of the malfunction of these services, we need to provide alert and response systems. In other words, an alert will be sent to us etc. This device is useful because it facilitates good working between the remaining functional modules

Pros and Cons of Microservices Architecture

As microservice architecture progresses from inflated expectations to disillusionment to an upward journey to enlightenment along with the hype cycle, our awareness of its pros and cons has grown. What are the benefits and drawbacks of microservices, then? For the most popular stuff that we run into, read on.

Pros of microservices architecture

In recent years, microservices have become hugely popular. Mainly, since in the era of containerization and cloud computing, they come with a few super-useful advantages. 

• INDEPENDENT: The value of the design of microservices is that each service is built and implemented independently of all other services. This implies that an upgrade to anyone component does not cause the entire application to come down, only the component in question, to deploy the update. This facilitates increased uptime and safer processes for deployment.
• TARGETED: Similarly, just as programs are built separately, the architecture of microservices makes it simpler to incorporate various parts of an application using different languages. This is desirable when a particular language is better adapted or aimed at a specific task.
• FLEXIBLE: Since all communication takes place across the network, there is more flexibility in terms of how each endpoint is composed instead of within the same in-memory phase. This also makes it easier to contribute to a project with teams with varying skill sets without wasting time learning a foreign language or working outside of their areas of expertise.
• ROBUST: Microservice architecture applications are more robust as a whole. If any service fails, where there is a loose connection between services, there is a better likelihood that the application as a whole will continue to provide users with value. Robustness depends on the quality of the services, how they communicate, and whether fault-tolerance is configured for the application.

Cons of microservices

• REFACTORING: Certainly, if the application's different behaviors are well known and easily isolated, a microservice architecture will have some additional advantages. But suppose a project in this style has been introduced but was the proper link between components initially misunderstood? It is much more difficult to refactor an application across several services than to refactor a monolith. Moreover, it would be vital to manage any configuration changes between all affected teams. Suddenly, when functionality from one service has to be ported over to another, using different languages with different components does not seem like such an advantage.
• COMPLEXITY: Splitting an application into multiple independent services creates more objects to handle theoretically diverse implementation processes, as previously mentioned. At once, the adversity of deploying the entire application can be increased.
• EXPERIMENTATION: Due to the increased number of nodes needed, spinning up test environments is more involved with microservices. Tools such as Electric Flow make it easier to handle and monitor these objects, one can't ignore this issue.
• PERFORMANCE: The overall performance is another potentially affected region. There is much slower communication over a network than in memory. That may be trivial for many applications, particularly as network speeds increase.

Microservices in the Cloud: An Example

As they are lightweight and easy to scale and deploy, microservices are often run as cloud applications. Several microservice-friendly features come with common cloud platforms, such as:

• Resources on-demand
• Pay as you go 
• As code, infrastructure
• Ongoing Implementation and Distribution

Cloud microservices are deployed in containers, and that's how you can make the most of the infrastructure. Besides, containers are isolated, run anywhere, and create a predictable atmosphere. However, without using containers, it's also possible to deploy microservices in the cloud.

In a nutshell, Microservices often work best with companies that need to had a more diverse user base. Architectural advantages and drawbacks of microservices vary significantly from conventional monolithic architecture, and this model is not suitable for every organization. However, the considerable change to this modular architectural design occurs for a reason: more businesses understand the need for quicker, simpler, more agile application development, and microservices enable this in ways that monolithic architecture can solely not.
