]]> In the previous post we talked about Vagrant, a tool that can help us manage the creation of virtual machines. In this post we will focus on another tool called Ansible. It is based on the concept of roles: on each virtual machine will be installed a series of specific roles. For example, we will create 3 roles, one that will install Docker, and two additional ones that will download and run a Docker container application.

]]> In the previous post we mentioned the potential of cloud computing thanks to the virtualization layer. For years we have been using Virtual Machines (VMs) to house multiple “copies” of the same service. This allows you to add or remove instances, ie, scale horizontally. By contrast, the new trend for some years is moving towards the use of containers. First with LXC, afterward Docker, etc.

]]> More and more companies decide to host their services in the cloud. The advantage of a cloud providers is the hability to use only the resources we need at all times, rather than paying the cost of a fixed number of servers. This elasticity is the result of using a virtualization layer: usually pay for virtual servers (virtual machines or containers).
