In the previous articles we created our infrastructure on AWS and configured the services. All using Ansible and creating an infrastructure as code. When the number of servers or services grows, keeping track of their names clearly can be complicated. This…
In the previous article we showed you how we created our infrastructure as code. This article describes how to configure services within our EC2 instances. Provision Backend Let’s start with a bash script to run the playbooks:
|
1 2 3 4 5 6 7 8 |
./provision_nuvola_backend.sh --limit "tag_nuvola_type_${ENV}_backend" ./provision_nuvola_dbserver.sh --limit "tag_nuvola_type_${ENV}_database" ./provision_nuvola_routine.sh --limit "tag_nuvola_type_${ENV}_routine" if [ "$ENV" != "prod" ]; then ./nuvola-init-not-prod-env.sh --env ${ENV} ./deploy_nuvola.sh --limit "tag_nuvola_type_${ENV}_backend" --env ${ENV} fi |
Here is the playbook…
In the previous article we described the reasons that made us change the provider. In this article we will describe how we built our infrastructure as code. As a first step let’s create a bash script to run the playbook:

1 2 3 4 5 6 7 8 9 10 11 |
:~$ ./infrastructure_nuvola_env_aws.sh --env prod #!/bin/bash . libs/extra_option_parser.sh … ansible-playbook --vault-password-file secrets/infrastructure_nuvola_env.secret \ ansible/infrastucture_nuvola_env.yml \ -e"$EXTRA_OPTIONS" |

In this series of articles we will describe our migration experience to AWS. Why a migration? Our old provider had limits. We had to overcome. In particular: No automation No flexibility No autoscaling If we wanted to grow it was…
In this article we are going to describe how we realized our RDS infrastructure using Ansible as automation tool. We’ve completely avoided using AWS GUI, both for implementation and management activities. Our aim was to develop a parametric infrastructure, able to…
This article starts a series of posts regarding a case-study about Symfony and multi-tenancy. Subject of the case-study is our flagship software Nuvola, a multi-tenancy product for schools, used since 2013 by more than 1 thousands Italian schools. Nuvola let them fulfill…
Saturday the 15th of October we leaved the comfort of our couches (have we already said we are a distributed team from all around Italy?) to leave to the glorious destination of Rome! The ancient town best known for the…
Getting informations on a running instance from the inside is a tedious task and it’s usually done in an insecure and error prone way. With this article we want to show you our way to get instance tags from the…
It’s said necessity is the mother of invention and in this article we’ll show the reason why we initially wrote s3-pit-restore. Our infrastructure heavily rely on S3 object storage to store the several millions files our users everyday produce. S3…
Sometimes happens, as it happened to us, that you have one or more services you want to share between your VPCs. For us, the case was for an ELK stack that we use internally to monitor the state of our…
