Once we have the network layer, we can deploy the storage layer. The bastion host is not represented in this layer, we are going to provision it using another layer. Moreover, we are going to use one Bastion host in the public subnet to access the services provided by the host from the company network. The host instances with the docker images will be deployed only in the private subnets thus we can avoid direct access from ‘outside’, but in order to not fully isolate and to have internet access of the services, we are going to use NAT Gateways in the public subnets. The main component is the VPC where Airflow will live isolated, this wraps around the 2 private and 2 public subnets which spread across 2 availability zones. Not only because this is the bottommost layer, but also because here we lay down the security concept of the whole installation. This layer is a fundamental part of the deployment. Different (DEV/TEST/UAT) environments are recommended to be deployed so a fully managed CI/CD pipeline can be defined on the top of this architecture as well for the DAG jobs. if we are about to change something on the top layer, we can do it without deleting or making any modification on the layers below.Īirflow Deployment Cloudformation modulesĪs you can see at the top layer the Airflow Service can have multiple instances, thus we can deploy for example multiple environments. With this modularisation concept, the development and the maintenance of the stack are easier, these layers are logically separated. The whole stack is split into 4 main layers. In the case of AWS, it usually means Cloudformation.

IaC (Infrastructure as Code) is one of the main principles we have to follow. This post is going to show you a secure deployment concept on AWS ECS provided by Infinite Lambda. The two available cluster types on AWS are AWS ECS or Kubernetes. On AWS there is no Airflow as a Service so we have to deploy it ourselves which requires a bit more expertise. If our stack is already in Google Cloud then we can choose Cloud Composer as an option which is for sure an easy start. Are you ready to use it? Alright, only one thing remains – deployment. It has a nice UI for task dependencies visualisation, parallel execution, task level retry mechanism, isolated logging, extendability because of the open source community it comes already with multiple operators and on top of that companies can define their own operator as well. The following section contains errors you may encounter when using the Docker container image in this repository.Apache Airflow has became de facto in the orchestration market, companies like it because of many reasons.
