Microservices have rapidly become the latest entry in the ever-expanding library of buzzwords that are present in the technological industry. A variant of the Service Oriented Architecture (SOA), the microservice architecture takes advantage of cloud tech to make their system faster and more agile. Many developers swear by the new architecture, while many stick to the tried and tested monolithic system that has been in use for several years.
However, unlike the time when computers were the main device used to run the software, today there exist several device platforms such as phones and tablets which require more flexible functionality and portability of software. This article aims not to convince anyone to switch from monolithic, rather, and we hope to further solidify microservice architecture as a strong alternative and a prerequisite skill for all developers to learn.
The following are the top 10 reasons to learn microservices and to decide if it is right for your software:
Microservice architecture allows you to scale individual parts of your application separately, as you analyse all the pieces and see their requirements. Unlike in monolithic applications, where horizontal scaling would be required, utilizing the entire package with the same amount of resources, increasing the overall cost of scaling up onto different devices and being an all-around inefficient design principle.
Microservice architecture enables you to configure smaller pieces of your system individually, without having one part affect another. Moreover, due to the possibility of individual parts of the system being developed separately, there is more chance of delegation of responsibilities, allowing multiple teams to work simultaneously on the service, without one team interfering with another’s schedule.
Microservice architecture also works better with larger applications, or as an application grows, as the deployments can be separated into smaller and more workable parts. This cannot be done in the Monolithic architecture as everything is tied together and no module can be deployed separately.
As different teams work on different components with the same single-purpose, each team can focus on the maintenance of their components. Moreover, the smaller modules enable a continuous delivery and testing process, ensuring that your ability to maintain an error-free application is significantly improved.
If a single module fails, it will not affect the larger application. Unlike a monolithic architecture, where one error can halt the entire application due to its interconnected design – causing minor problems to snowball.
Training new developers become easier as only a small part of the application needs to be taught to them.
As the system is not governed centrally, microservice architecture opens up avenues for multiple technology platforms to be used in the development of the application. This allows you to use the right tool for a job, and most teams working in tandem help each other by developing such tools (or using premade open-source ones), that can better streamline other teams’ workflow.
Versatility in Technology stack:
Any new technology stack can be tried out at any point without completely committing to it. This is because changes can be rolled back on an individual service in an easier fashion as compared to monolithic designs where one change affected all – lesser code allows for more flexibility.
Easier entry point:
As microservices use event streaming technologies, it enables more straightforward engagement for teams to pick up and identify data, making it easier for a new developer to understand the function of a particular service.
Quicker market delivery:
With the aim of most markets demanding fast delivery of improvements and features, microservices can reach markets quicker as it works in fragmented services functioning together as a whole. This removes the need to rewrite code bases when adding or modifying features, enabling you to make changes only to the parts that are needed by the particular service in your application. Ensuring that the development time of each update is severely reduced.
When deciding to build your software with microservice architecture, one must keep in mind the balance with which they decouple and fragment their service software. Under-fragmenting or Over-fragmenting of your application can cause you to either not see the benefit of microservice or not being able to manage the weight of the multiple fragmented services; losing any benefit that the architecture could provide. Therefore having a more in-depth knowledge of both types of architecture – the traditional monolithic design and the more robust microservice architecture, would prove far more beneficial to you as a developer.
