Network environment requirements
The OutSystems services use the following ports:
- 12000 - OutSystems Deployment Controller Service
- 12001 - OutSystems Deployment Service
- 12002 - OutSystems Scheduler Service
For each server of an OutSystems environment, localhost:
- must resolve to 127.0.0.1 (IPv4)
- must be accessible by HTTP on 127.0.0.1
It is possible to configure some of the ports used. Check the Configuration Tool in your OutSystems installation directory to learn more.
The table below details the ports that need to be accessible in each server of an OutSystems environment for publication and runtime connectivity. If a server has both roles (Controller and Front-End), then consider the ports for both profiles on that server.
|SysOps||Server||22/3389||TCP||Access the server through SSH or Remote Desktop|
|End-Users||Front-End||80||TCP||Applications HTTP access|
|End-Users||Front-End||443||TCP||Applications HTTPS access (always required for mobile apps)|
|Development Tools||Front-End||80||TCP||Deploy applications to the environment|
|Development Tools||Front-End||443||TCP||Deploy applications to the environment|
|Front-End||nativebuilder.api.outsystems.com||443||TCP||Generate mobile apps (more info)|
|Front-End||Controller||5672||TCP||Cache Invalidation Service connection|
|Front-End||Controller||12000||TCP||OutSystems Deployment Controller Service connection|
|Front-End||SQL Server / Oracle||1433 / 1521||TCP||Database connection|
||12001||TCP||OutSystems Deployment Service connection|
|Controller||SQL Server / Oracle||1433 / 1521||TCP||Database connection|
The following table lists the ports that should be open to correctly monitor OutSystems. A failure on opening these ports may result in warnings and error messages.
|Front-End||Controller||12000||TCP||OutSystems Deployment Controller Service Monitoring|
|Front-End||Front-End||12001||TCP||OutSystems Deployment Service Monitoring|
|Front-End||Front-End||12002||TCP||OutSystems Scheduler Service Monitoring|
|Controller||Front-End||12001||TCP||OutSystems Deployment Service Monitoring|
|Controller||Front-End||12002||TCP||OutSystems Scheduler Service Monitoring|
In case you are using a hybrid infrastructure, where some part is in OutSystems PaaS and another is managed by yourself, it is possible to create a VPN connection between the environments. Learn more here.
If you are using a container-based hosting technology for deploying OutSystems applications, your network topology and firewall configuration should fulfill these requirements:
- The Container Runtime network endpoint must accept connections on port 80;
- The platform database and logging database addresses (and ports) must allow connections from the Container Runtime;
- The Platform Server Deployment Controller port (12000) must allow connections from the Container Runtime.
SSL offloading is required to run applications in containers. Follow the instructions presented in End-to-end SSL and SSL Offloading, namely the step instructing you to insert a record in the
Even though OutSystems is built to scale horizontally, you need to consider the network latency between the database server, the Platform Server, and the front-end servers. For this reason, it’s advisable to have all servers that make up an environment, running under the same provider.
As an example, if you are using Amazon RDS as your database server and running the Platform Server on your own infrastructure, the application’s performance will be degraded.
Network infrastructure requirements
To use LifeTime to manage your application lifecycle, you need to have bidirectional communication between the front-end of the LifeTime environment, and all other servers (front-ends and deployment controllers) of your OutSystems Infrastructure.
In case HTTPS is not supported, LifeTime communicates with the environments it manages by HTTP.
Applications must be deployed as follows:
|LifeTime Front-End||Environment Front-End||80||TCP|
|Environment Front-End||LifeTime Front-End||80||TCP|
