What are the essential skills for Microservices developers?

  • essential skills for microservice developers

Microservices have been gaining tremendous popularity, and many developers have been working on them lately. This is a trend that has been bringing many changes into the daily lives of people. Skills that were considered niche in the earlier times have now become the need of the hour. 

If you are looking forward to working on microservices or seeking a job as a microservice developer, then the blog is for you. 

Since there is much hype about microservices, we have mentioned a few critical skills that micro developers need to work on to become successful in this field. 

Here are the essential skills which microservices developers need: 

1. Architecture Knowledge:

 In simple words, microservices are architectural patterns. Therefore, it is always a better idea for microservices developers to be familiar with the different languages. This is because most of the stuff in microservices happens in these high-end languages. Thus making it essential to know in and out about these languages.

 For microservices developers, it is pretty essential to understand the typical patterns of microservices. The basic concept is that the developers should be well-versed with practices because if they are not, then they will choose the wrong solutions. Having proper knowledge of the practices simplifies the work and increases the quality by 10x times.

2. Domain Modelling:

Even if one understands their architecture and patterns quickly, it is undoubtedly quite hard to succeed in no time when it comes to Microservices. It can be pretty challenging to split responsibilities among various parts of the system. All one needs to do is be amazing at domain modeling and understand how to assign blame. 

One strategy is that one needs to draw more. Drawing with their team and other people involved in their project is a fantastic tool for fostering a better understanding of their domain. Being great at linking their domain and design is a valuable skill universally, especially for software developers.

3.  DevOps and Containers

One of the unique ideas behind microservices is to work in the DevOps way.  People need to take ownership of their service in almost all forms, be it writing code for use in production. Even if one is not planning to deploy in production, one should know how deployment is likely to look even if one is not deploying it. 

There is no hiding here as one will have to become quite familiar with containers, Docker, Kubernetes, etc. the best part is that they can get Docker on their machine, and it is undoubtedly worth it. Besides containers, one needs to understand Queues, messaging, databases, some clouds, etc.

Even though it might seem like a lot of trouble, one doesn’t need to stress as several experienced colleagues in their team can help. Of course, no one is likely to become an expert overnight, but learning these technologies might be new to them if they weren’t exposed to the operation of any things.

4. Security:

As one might imagine, securing several things is way more challenging than securing one element. However, security concerns are in front of everyone’s minds when individuals work with monoliths with microservices.

When it comes to securing data at rest, the microservices have their way of securing configuration. But, above all, these are some elements where security cannot be compromised.

5. Testing:

Ideally, testing is one of the things that can be quite deficient in their productivity and success is undoubtedly having services that don’t fail regularly and don’t fulfill the contracts. People say that microservices are pretty tiny and look minor and less severe or business-like compared to substantial monolithic applications and some developers ignore the testing.

Above all, people shouldn’t miss it as they offer plenty of opportunities for creating amazingly tested and robust solutions, so one shouldn’t pass on it as it is way more than trivial, or unit tests aren’t likely to be the answer.  One needs to include tests including:

  • Unit tests
  • Service / API test
  • End to End test of the integrated system

6. Continuous integration:

As mentioned earlier, end-to-end testing plays a crucial role. Still, with microservices, one needs to ensure that everything works perfectly, and they should also see microservices interact perfectly. One can go quite far when testing such challenging conditions in isolation.

One of the best ways to deal with the issue is to set up integration regularly whenever they merge with a problem; they need to set up the code to their master and deploy it to an integration environment where different tests tend to run.

7. Language

Ideally, the microservice architectural pattern isn’t likely to be associated with any programming language, but most tasks are done in Java. Above all, it is essential that anyone applying for any programming job needs to have skills in various languages; several staffing experts are specially trained and experienced to recognize a candidates’ Java skills by scanning their resume and deliverables they would have done in the past. If one’s past projects aren’t there for review or even if they are, then the hiring managers will likely use coding tests to verify these skills.

8. Back-End Development

As Microservices is most likely to be a distributed system, there are likely some challenges on the backend that would befuddle several developers. However, one’s familiarity with backend development will set them apart to solve software development challenges as they are experienced quickly.

DevOps is the newer way of working and is all set to shake up how we see the developers’ job. This is the perfect time for software developers to try their hands on something new and gain more significant insights. 

With these essential skillsets, you can develop yourself as an advanced microservices developer.
