Help your business apps with microservices.

We continue to work with the monolithic architecture as a base: a single company application that contains all our business (known as the Backend). As everything is under the same support, any correction, change, and new functionality will affect all levels and will force you to install all the content again.

This can be a real problem, because the code can be “broken” in many ways, leading to tedious maintenance and some ideas not even making it to the deployment stage.

As we discussed in Study the performance of your apps with Azure App Insights, it’s important to maintain control over your apps, and helping to reduce workloads is a great way to do that.

The answer? split your work

The best option to divide workloads within your apps is to use microservices: a new architecture that allows you to separate functionality into independent spaces, avoiding the previous problem of all your work resting on a single code.


With this architecture, your application is articulated as several connected services, but not united: each service is self-provided and should be dedicated to a specific business capacity.

More separate code makes it easier to maintain the SOLID principles of programming and avoid what we might call dirty code (difficult to read and many lines). In addition, the changes we make will be installed only where we need them. This speeds up the installation and update process.

There is only one problem, and that is that each project may require several microservices, and installing each one as a separate web consumes a lot of resources. That’s what Kubernetes is for: a technology that allows microservices to be installed efficiently, with each container containing the strictly necessary resources. The key is to optimize the process and use the minimum possible resources.

How does Kubernetes work? How do I start working with it?


At the highest level, Kubernetes is a cluster of local or virtual machines. Each machine (or node according to Kubernetes) share processing resources, network connection, and storage. A “master” node connects to those machines, which will run workloads in groups separated by containers, with the central node serving as an administrator.

Our staff controls everything from the main node through a command interface in your OS. From there, after passing through the API server and the control manager, the changes or orders are issued to the worker nodes.


Once we have everything configured, we can start to deploy the applications and their respective workloads. Kubernetes has all the tools to do this, as well as visualization capabilities to see the status of each machine and manage resources automatically, without taking up your time.

The last step is to organize the management and permissions/access to our managers. To do this, a namespace (bundling method in Kubernetes) must be created, with which you can start granting such permissions.


What do I get, then, from using microservices?

The new microservice architecture optimizes resources, using just what is necessary. It will also help us have clean and easy-to-read code, making it easy to add new features efficiently. But above all, it will keep our operations running as long as possible and at peak performance.
