Flux de deploiement

Option 1 : Deploiement AWS (Production)

    participant Dev as Developpeur
    participant TF as Terraform
    participant AWS as AWS
    participant ANS as Ansible
    participant WM as webMethods

    Dev->>TF: terraform apply
    TF->>AWS: Cree EC2 + Security Groups
    AWS-->>TF: Instance ID + DNS
    TF->>ANS: Execute playbook
    ANS->>AWS: SSH connexion
    ANS->>WM: Installation CC/SPM
    WM-->>Dev: Services disponibles

Option 2 : Deploiement Local (Docker)

    DC->>SUP: Demarre containers
    SUP->>WM: Lance CCE + SPM
    WM-->>Dev: http://localhost:8090

Option 3 : Deploiement Local (Vagrant)

Composants webMethods

Command Central (CCE)

Le coeur de l'administration webMethods :

Aspect	Detail
Role	Console d'administration centralisee
Ports	8090 (HTTP), 8091 (HTTPS)
Profil	/opt/SAGCommandCentral/profiles/CCE/
CLI	sagcc

Platform Manager (SPM)

L'agent de deploiement sur chaque noeud :

Aspect	Detail
Role	Gestion locale des produits SAG
Ports	8092 (HTTP), 8093 (HTTPS)
Profil	/opt/SAGCommandCentral/profiles/SPM/
Communication	Vers CCE via REST API

Ports et securite

Matrice des ports

Service	Port HTTP	Port HTTPS	Usage
Command Central	8090	8091	Administration
Platform Manager	8092	8093	Agent local
Integration Server	5555	-	Services REST/SOAP
Universal Messaging	9200	-	Messaging
IS Diagnostic	9999	-	Debug
SQL Server	1433	-	Base de donnees
Keycloak	8585	-	Authentification

Security Groups AWS

# Regles d'entree configurees
ingress {
  from_port   = 8090
  to_port     = 8094
  protocol    = "tcp"
  cidr_blocks = ["0.0.0.0/0"]
  description = "webMethods CC & SPM"
}

ingress {
  from_port   = 5555
  to_port     = 5555
  protocol    = "tcp"
  cidr_blocks = ["0.0.0.0/0"]
  description = "Integration Server"
}

Gestion des processus

Supervisor (Containers/VM)

[program:commandcentral]
command=/opt/SAGCommandCentral/profiles/CCE/bin/startup.sh
autostart=true
autorestart=true
stdout_logfile=/var/log/supervisor/cce.log

[program:platformmanager]
command=/opt/SAGCommandCentral/profiles/SPM/bin/startup.sh
autostart=true
autorestart=true
stdout_logfile=/var/log/supervisor/spm.log

Avantages de Supervisor :

• Redemarrage automatique en cas de crash
• Gestion unifiee des logs
• Compatible containers (pas besoin de systemd)
• Interface de controle (supervisorctl)
