# FIWARE: Orion and Cygnus on AWS



This guide will help you to deploy Fiware's Orion and Cygnus (optional) components into a serverless architecture.



## What does this repository include?



1. An [AWS CDK](https://aws.amazon.com/cdk/) project in charge of provisioning the basic infrastructure with a VPC Network, Security Groups and two managed Databases, one Amazon Aurora Serverless (PostgreSql) and one Amazon DocumentDB. These are represented in the following stacks:



    - Network Stack

    - DocumentDB Stack

    - Aurora Stack

    - Fiware Stack (new stack replacing the deprecated docker ecs-integration)



## What doesn't this repository include?



Besides [WAF](https://aws.amazon.com/waf/) configuration to allow IP based access, this repository does not include any additional security mechanisms. However, we do recommend to read the [security considerations from Fiware](https://fiware-orion.readthedocs.io/en/master/user/security.html) and enable SSL communication. For the later, please read [create-https-listener](https://docs.aws.amazon.com/elasticloadbalancing/latest/application/create-https-listener.html) and how to enable this in [CDK](https://docs.aws.amazon.com/cdk/api/v2/docs/aws-cdk-lib.aws_ecs_patterns.ApplicationLoadBalancedFargateService.html#certificate)



## Architecture



![Architecture](image/arch.png)



## How to use it?



### 1. Requirements



Instal node v18.16.1 or greater.



### 2. Infrastructure



1.1 Create an [AWS profile](https://docs.aws.amazon.com/cli/latest/userguide/cli-configure-profiles.html) is recommended if you do not have it.



### 3. Configuring settings



Use the `settings.ts` file to configure your deployment. You can delete/comment the `cygnus` attribute if you only want to deploy Fiware Orion. You can also choose to deploy the 'fiware/orion' image or the 'fiware/orion-ld' from docker hub by configuring the `orionLD` attribute.



Additionally in the Orion construct you can add environmental variables, for more information check the following links:



- Orion: 



- Orion-LD: 



### 4. Deployer script



The infrastructure is deployed by this bash script:



`./deployer.sh `



After the deployment is completed, you can see these services running in you AWS account.



| AWS Service                     | Description                                 |

| ------------------------------- | ------------------------------------------- |

| AWS Fargate                     | Containers for Orion and Cygnus             |

| Application Load Balancer (ALB) | Load Balancer for Orion and Cygnus web api. |

| Amazon DocumentDB               | Database for Orion                          |

| Amazon Aurora Serverless        | Database for Cygnus                         |

| AWS WAF                         | Web Application Firewall for the ALB. \*    |



**NOTE**: WAF rules for the ALBs can be changed, please see this [reference](https://docs.aws.amazon.com/waf/latest/developerguide/aws-managed-rule-groups-list.html).



### 5. Demo



Follow the demo from the published blog: [How to build smart cities with FIWARE Orion Context Broker and Cygnus on AWS](https://aws.amazon.com/blogs/publicsector/how-to-build-smart-cities-with-fiware-orion-context-broker-and-cygnus-on-aws/)



## 6. Load Testing



[Loadtest for FIWARE Components](https://github.com/FIWARE/load-tests) provides load test for FIWARE Orion-LD



## 7. Clean up



If you need to clean up the resources, please follow steps below.



**[WARN] All data will be deleted by this step.**



`npm run cdk destroy -- --all --profile `



## 8. Known Issues



### 8.1 DocumentDB vs MongoDB



- [Issue in FIWARE github repository](https://github.com/telefonicaid/fiware-orion/issues/3778)

- DocumentDB does not port all the functions of MongoDB, like for example geospatial capabilities.



### 8.2 Docker ECS integration deprecation



`Docker Compose's integration for ECS and ACI is retiring in November 2023.` from 



You can upgrade your current existing deployment by following these steps:



> IMPORTANT: we recommend you to do a full backup of the database services Aurora RDS and Amazon DocumentDB before continuing.



1. Edit the `settings.ts` file to configure your ECS services and WAF settings.

2. Delete the `cygnus` and `orion` stacks from the [AWS Console Cloudformation](https://console.aws.amazon.com/cloudformation), be sure to select the region used to deploy.

3. Execute the deployer in your terminal: `./deployer.sh `

4. You will get a new endpoint for Orion, `FiwareStack.orionservice...: http://....elb.amazonaws.com/`

5. If you deployed with Cygnus, you can subscribe to it in the new URL: ``
