How to Sell microservices certification to a Skeptic
I first discovered the term “microservices” while researching microservices.com, the company that runs the microservices course at Google. As a developer, I find myself working on microservices all the time, mostly for the sake of learning and for the sake of learning about the more exciting and abstract aspects of microservices. Microservices is an umbrella term that encompasses the idea of services that are self-contained, independent, and asynchronous.
The term microservices can be confusing because we often see it used in different ways. From the perspective of the developers implementing microservices, microservices is really just a term for services that are loosely coupled. What this means in practice is that no one server is responsible for anything, so there’s no central coordination of operations. The only responsibility for a service is to make sure that it doesn’t create a bottleneck that would cause a single server to crash in a multi-service system.
In the context of microservices, we often hear the term “microservice” used to refer to services that are loosely coupled. That is, they have a single responsibility. For example, let’s say I have a website called www.mydomain.com, which only services the www. subdomain.
So when we’re talking about microservices, we’re often talking about loosely coupled services that are loosely coupled. For example, we have a website called www.mydomain.com that only services the www. subdomain. Now in this example, lets say that I have a separate web service called web.service that is responsible for serving the www. subdomain. I have a separate web service that is responsible for serving the subdomain.com.
I have a separate web service that is responsible for serving the subdomain.com. And you can see that if you try to call that web service from mydomain.com, the call is denied because they are not allowed to talk to each other.
That is because they are using the same ports.
This is a bit more complex than just using the same ports. A service can have multiple ports. The ports are specific to a service and will be used only by that service. But as long as there is only one port for a service, you can still have multiple services that are using the same port. It’s only when you try to connect to a service that you are denied the service will refuse to allow you to connect.
This is a bit of a strange one. Microservices are the “small, independent, autonomous, and loosely coupled parts” of a larger application (such as a web or mobile app). They are “programmed as a group with their own unique set of objects, events, and behaviors”, so their code can be broken apart into services that are not related to each other but still perform their functions. An example of microservice architecture that I’ve seen is the example code for this article.
Microservices are a relatively new topic, and I have never seen one in action, but the concept is quite well-understood and has a lot of potential. I think one of the problems with microservices is that many developers just assume that they will be able to pull off the microservices model without any need for an elaborate design or extensive testing.
The problem with this kind of idea is that, as long as a team of developers knows what they are doing, these services will work. Because it is a service, it will all work, and this would lead to a huge improvement in developer productivity. It is also the reason why, when I do my microservices book, I keep focusing on what I call the “microservice design”.
