Software developers are faced with the question of which type of architecture for their applications to choose – monolith or microservice. The difference between these two methods is huge – the monolith has been used for a very long time, while microservices are considered the latest developments. Microservices vs monolith Architecture, the differences between two main IoT technologies are described in detail.
What is monolith architecture?
Monolithic architecture for applications is a single unit that combines user algorithms, a database for storing information, and server settings for data transmission. if it is necessary to update the application with a monolithic architecture, the user needs to work on the server-side, which often leads to a decrease in system performance.
Despite their reliability, monolith services are considered obsolete and do not allow for scaling tasks, which leads to a decrease in the indexes of business development.
Differences between monolith and microservices
So, there are several basic differences between monolith and microservice architectures:
- Microservices are focused on developing applications based on several independent clusters for storing information.
- To update monolith applications, the entire database must be affected. Microservices can be corrected in small portions, which does not slow down the system.
- Decentralized microservices ensure that the entire application runs smoothly, even if individual clusters fail.
- With a monolithic architecture, it is almost impossible to make global changes to the principle of paring. When using microservices, the system can be flashed using innovative developments, which significantly expand the business capabilities of the owner.
- Monolithic architecture works in a single interface and cannot be shared between different developers when compared to microservices.
Advantages of monolith applications
- Proven technology, easy to develop, requires one database to create.
- The risk of errors when making changes is eliminated, which leads to stability of work.
- Applications do not require the use of the technology API, which greatly simplifies the work, reduces the response time of the system to any request – the system does not send a response in a large number of clusters.
- Such applications are less likely to fail. They are easy to take into account, control, and correct.
- Once developed, such programs are easier to test in action and also to customize.
- When an error is found, there is no need to diagnose each cluster, as in microservices.
Disadvantages of monolith applications
- When updates and renovations are needed, the developers have to intervene in the basic structure of the entire application, which takes a lot of time and almost completely blocks normal operation during the period of changes.
- It is difficult to integrate innovative developments into such a system, which significantly slows down the spreading of the business.
- The architecture can be adjusted and improved only by a limited number of developers from one team.
Advantages of microservices
- Huge opportunities for the decentralization of the system.
- There can be exactly only databases in the application structure, how many microservices are used when creating it.
- Microservices are more suitable for rapid business development
- If any error is found in one of the clusters, it can be corrected without affecting the entire system.
- System adjustments and updates can be carried out without slowing down the application.
- In the architecture of microservices, innovative solutions can always be integrated into the system, which contributes to the development of the business and the solution of important problems.
- If an update is required, developers do not need to change the entire system operation algorithm.
- The microservice system can always be scaled, it is always possible to add different languages and algorithms without global changing of the application structure.
- When using microservices for business, fast processing of operations and solving all problems, allows you to get a higher income
Disadvantages of microservices
- Considering a large number of clusters, to avoid errors, it is necessary to constantly keep a record of each change and intervention in the application.
- If an error occurs, before eliminating it, it is necessary to check each element of the system to accurately identify the damaged cluster.
- Microservices can be suffered by the cyberattacks much oftener, than a monolith, because of a big amount of independent clusters.
- Microservices are very difficult in repairing and testing after developing, installation and launching because the developer should check all of the decentralized parts of the system separately. It can take a lot of time and demand much more professional skills as monolith systems.
- Microservices cannot work clearly without the instant services that ask for a lot of additional expenses.
Why do more and more companies use microservices architecture?
Nowadays, a large number of companies still use a monolithic architecture, which will cause constant interruptions when trying to retool the system.
Due to this, large enterprises like Amazon, Netflix, or Uber have long since switched to microservices. Clients of these services no longer experience any inconvenience while using applications – they don’t even notice how they are being debugged.
The reasons for choosing the monolith architecture
- You won’t launch your application and start to earn money as soon as possible.
- Your application doesn’t require instant upgrades.
- You don’t have enough budget to spend money on service maintenance.
The reasons for choosing the microservices architecture
- Your future application requires rebooting and scaling every day, week, or month.
- Such an architecture will suit you if you have the necessary amount of qualified staff to maintain the application.
We have developed a new Internet resource for a major airline with a worldwide reputation. Our system is based on the correct interaction of microservices and the possibility of complete decentralization of the application. The website works on both PC and mobile devices; the most famous operating systems have approved the download of mobile applications.
The reason for placing an order for a complete reorganization of the site was the use of an outdated monolithic architecture, which significantly hindered the development of the enterprise’s business.
After carrying out comprehensive revisions, the application allowed consumers to use different services independently of each other. The in-house support team regularly modernizes them and integrates innovative developments into them.
We can say with complete confidence that modern realities require more and more implementation of microservices when developing applications. Undoubtedly, decentralized systems turn out to be much more convenient and secure for both users and the owners of websites.
