Microservices Pros and Cons

Many technology trends come and go but only a few of them are worth their hype. One such latest trending technology in the software industry is Microservices. It’s obvious that if these microservices are trending then they ought to be beneficial. But on the other hand, this is one of the emerging technologies which means it’s still not refined. So, it also ought to have some disadvantages along the way.

Therefore, in this article, we are going to discuss microservices pros and cons. We will see what this trend has to offer and what challenges you have to endure to get that benefit. And at the end, we are also going to look at some common applications of microservices. So, without any further ado, let’s get started with the pros and cons of microservices. But first, let’s take a peek at what this microservice is.

Microservices is a unique approach to creating software where the entire product is chunked down into small services. Every service here has its processes and can communicate with lightweight mechanisms like XMPP, AMQP, and HTTP.

With the use of microservices best practicesit allows you to develop and deploy every service independently. Additionally, you can use any programming language or combination of technologies to write these microservices. The most common languages used to build microservices include NodeJS, Java, and GO. Microservices are largely used to create a new feature or scale up a software application.

In comparison to monolithic software applications, microservices are rather simple and more efficient. This explains the overall low costs of microservices. Moreover, microservices don’t need communication and coordination at the same level as monolithic apps because they are self-contained. Using microservices helps businesses pick the most suitable technology and frameworks for their projects. This results in reduced errors and increased efficiency.

Scaling microservices horizontally is an easy task. So, if you are working on a project where scalability is a requirement, then microservices are an ideal solution for it.

Apparently being small and modular is a benefit for microservices as it enables the developers to deploy them quickly in comparison to monolithic apps. Such agility can be very beneficial for companies that must respond quickly to the changing market trends. 

Being small and self-contained presented microservices with yet another benefit after agility. They can be updated quickly and easily. As you know, every microservices has assigned a specific task to perform, so the chances of errors are reduced drastically when you make an update. Similar to updates, maintenance of the application also becomes less risky and time-consuming.

Another benefit companies get by using microservices is the increased modularity which can come in handy in time of making quick changes to their applications. When you break down an app into small pieces, it becomes easier and less risky to implement those changes. Additionally, understanding how a small service works and fits into the overall application is easier to understand.

As we already discussed, microservices are made up of various small independent services. Being able to deploy these services independently provides companies with more control over their application. This increased control can help businesses adjust to market trends and achieve their goals quickly. Moreover, companies using microservices never have to face the ‘monolithic blues’ that occurs when an app becomes too big to manage efficiently.

Although there are many advantages to these small and self-contained microservices, there lie disadvantages too. And one of the major challenges that comes with managing microservices is that it is highly complex. Managing several independent services will always be a complex task. This also makes the work of tracking bugs more complicated and time-consuming.

Since microservices need more coordination and are more complicated, they need more development time. Deploying a large number of independent services will also consume a considerable chunk of your time. Additionally, if a developer wants to work with a microservices-based software application, they need to familiarize themselves with multiple technologies first.

Because microservices are written using various programming languages and technology stacks there is a limit to which microservices can reuse the code. This limitation might result in increased costs and development time. Moreover, sharing code between microservices can be very challenging.

Microservices-based applications are generally spread out across multiple devices and servers which makes it hard for developers to test or debug them. Because just to test such an app, you first have to have access to all the devices and servers that are part of the system. So, if a system is as large and distributed as microservices, testing, and debugging can be difficult tasks.

As we discussed in this blog, microservices come with many benefits over monolithic applications. But it has a few limitations too. So it is highly recommended to you that you must carefully weigh these pros and cons against your list of requirements before you decide on whether microservices are the right solution for your business or not.
