6 Potential Drawbacks of Microservices
Below are a few of the Potential Drawbacks of Microservices
The most notified drawback of the microservices is that it is more tangled than most monolithic applications. It also engages a lot more programming than conventional applications, requires colossal efforts, careful scheduling, and tactically applied automation to ensure communication, supervision, testing, and arranging process to run smoothly. The complexity of microservices brings confronts to sustain several programming languages and frameworks. All the realistic tools are likely unsuited with new service dependencies.
Further points of Microservices complexity are:
One more disadvantage which occurs due to the use of the microservices technique is costly as compared to monoliths techniques. Its services require more communication between each other, which increases insignificant calls. This can lead to network delay and high processing costs, but this is never seen in traditional techniques.
Developers have to undertake this point of the problem and always try to reduce insignificant calls to evade trouble.
Microservices includes some security challenges as compared to monolithic applications development. These challenges occur due to an intense increase in the number of data exchanged between different in-between modules.
Working is done with several tiny containers that mean you are revealing more of your data to the network that result in revealing more of your data to professional hackers or attackers.
We all know that containers are highly-replicable, which means even a single weak point in any module can cause a big problem, and it will become easy for hackers to access the source code used in various applications.
Using microservices need lots of expert training. You can opt for experts that give microservices training.
Depending on the consistency of the app, every Microservices have their API. It is far easy to change Microservices without disturbing the external systems for this. But if you modify API (application programming interface), then every application supporting microservices will be ostentatious if the modification is not compatible with the internal core or system.
Testing and training is the major part of every application and is almost the end phase of every application developed. Traditional monolithic applications testing were done by just launching the full developed app on the server, and we have to confirm its connectivity with the main database, but in the case of an app developed in using a microservice approach, testing is done only after confirmation of each module develop which can cause time wastage if any of the module workings is not confirmed.
6. Execution-
Execution of the application is also affected by the microservice technique as transfusion over a network is estimated slower than in memory. This may be challenging for many applications and maybe not appropriate though even network speeds improve randomly; it brings a drawback in this approach.
