Defining a correct infrastructure for each project is important to assure reliability, good performance and scalability in the application. Choosing a wrong infrastructure can bring problems in a production environment.

Sophilabs recommends host your application in Amazon infrastructure and use containerization.

Amazon Web Services

Amazon Web Services provides a set of scalable and reliable services that help you to host and monitor your web applications. Amazon provides solutions to:


Using Containerization is important to isolate your web application server and database.

For example, a simple web application can use 3 containers.

  • A Frontend Server, which hosts a javascript application and makes calls to a Backend Server to do any operation with the system.

  • A Backend Server, which exposes an API for operating with the system.

  • A Database Server to store persistent data, using PostgreSQL or another database engine of your choice.


When we talk about containerization, the name Docker immediately comes to mind.

Even though there are many containerization solutions, Docker is the most popular and is used in many production environments. The development community has come to the consensus that Docker is the most reliable containerization technology.

For these reasons, we recommend the usage of Docker to define the containers that your application requires.

How to start

If you don't have experience working with docker or containers the following links will help you.

Docker guidelines

There are several ways to define an application using Docker containers. In this linkyou will find some patterns that docker team recommends to maintain small images with a fast building time.

When you write a Dockerfile, you should consider the following guidelines.

Docker compose

We recommend the usage of docker-compose to define and running Docker containers. This tool is useful because allows you define multiple containers in a single .yml file. Moreover, with docker-compose you have mechanisms to define environment variables and mount volumes in declarative mode.

Installations guides, tutorials and best practices can be found in the following link.

Docker registry

Docker registry is a repository where you can store and share your built images. The docker registry allows you:

  • Maintain traceability of the different versions you build.

  • Share and store the images you build in a secure way.


In some cases your application might require having fault tolerance, dynamic scalability and zero downtime between releases. In these cases, having a Container Orchestator is a good option.

Our recommendation for this task is using Kubernetes.

How to start

If you don't have experience working with kuberntes the following links will help you.

  • Glosary

  • Installation

    • Kubernetes was thougth to run inside a cluster for production environments. If you want execute your kubernetes cluster in a local environment we recomend to use Minkube.

    • To interact with your cluster you will need the kubectl, the Kubernetes command line tool. To install and configure this tool review the following link.

  • Kubernetes tutorials

Kubernetes best practices

Take a look at the following link to know the best pratices that Kubernetes team recommends.


We strongly recommend the usage of the tool helm.

This tool helps you in the definition of the components that you need. Using helm you have facilities to define templates with your Kubernetes objects using variables. The variables are substituted with the content of a .yml file when you upgrade a cluster. This feature allows you have a single template for all the environments.

Kubernetes operations (kops)

For development environment you can host your cluster in a virtual machine using Minikube. However, for production environments you should host your cluster using Amazon, Google Cloud or DigitalOcean for example.

The comamnd line tool kops allows you interact with the infraestructure in a esay way. You only need to define it in a config file.

For installation instructions and first steps with the tool visit the following link.

Domain Names

We suggest using Domize to see what's available. Use DNSimple to buy and maintain domain names if a client hasn't registered a domain name yet.

SSL Certificates

Buy a wildcard certificate from DNSimple. The wildcard (*) lets you use the same certificate on www., staging., api., and any other future subdomains. SSL and DNS are tightly coupled. If we're doing any work with SSL, we need to make sure we have access to make DNS changes, such as adding a CNAME record. When working with a client that has a DNS department, schedule time during off-peak hours in order to pair program with their DNS personnel to ensure smooth sailing. We can accidentally take down a site that is all SSL if this work isn't done methodically.
