El 15 de septiembre de 2026, todos los entornos de Cloud Composer 1 y Cloud Composer 2 versión 2.0.x alcanzarán el final de su ciclo de vida previsto, y no podrás usarlos. Te recomendamos que planifiques la migración a Cloud Composer 3.
Los servicios de Cloud Composer y GKE usan intercambios de tráfico de VPC para establecer conexiones entre los componentes de los entornos de Cloud Composer (proyecto de cliente y proyecto de usuario) y entre un clúster de GKE y un plano de control de GKE.
Si tu proyecto tiene una configuración de red a gran escala, como con cientos de redes y muchos intercambios de tráfico de VPC configurados, cuando intentas crear nuevos entornos de Cloud Composer, las operaciones pueden fallar debido a Errores de cuota de reglas de reenvío, subredes o VPC.
Los errores que puedes encontrar son los siguientes:
Se alcanza la cantidad máxima de intercambios de tráfico de VPC por red de VPC.
La cuota predeterminada para una cantidad de intercambios de tráfico de VPC dentro de una VPC es de 25 (a menos que solicites un aumento de esta cuota).
Se alcanza la cantidad máxima de rangos de IP de subred principales y secundarios.
La cuota para este parámetro es de 400.
Se alcanza la cantidad máxima de reglas de reenvío en el grupo de intercambio de tráfico para el balanceo de cargas TCP/UDP interno.
La cuota para este parámetro es de 175.
Para obtener más información sobre las cuotas predeterminadas para las VPC en Google Cloud, consulta Cuotas y límites.
Acerca de las redes a gran escala para entornos de Cloud Composer
Para superar los desafíos relacionados con estos límites, puedes organizar tus entornos de Cloud Composer en varias redes de VPC conectadas a tu VPC principal/troncal como se describe en las siguientes secciones.
Esta solución se aplica a las situaciones de VPC compartida y no compartida.
Configuración de red a gran escala en una situación de VPC no compartida
A fin de crear una configuración de red a gran escala para Cloud Composer, sigue estos pasos:
Crea una red de VPC troncal.
Esta red actúa como un concentrador para redes de VPC individuales que alojan entornos de Cloud Composer.
Crea redes de VPC dedicadas para los entornos de Cloud Composer. Puedes combinar varios entornos de Cloud Composer en una red de VPC. Por ejemplo, puedes nombrar a estas redes composer-vpc-1, composer-vpc-2, etcétera.
Configuración de red a gran escala en una situación de VPC compartida
Para resolver el problema de límites de intercambio de tráfico entre redes en una red de VPC compartida, organiza tus entornos de Cloud Composer en varios proyectos y redes de VPC conectadas a una VPC troncal.
A fin de crear una configuración de red de VPC compartida a gran escala para Cloud Composer, sigue estos pasos:
En el proyecto host, crea una red de VPC troncal.
Esta red conecta las redes de VPC individuales para los proyectos de servicio que ejecutan entornos de Cloud Composer.
En el proyecto host, crea redes de VPC para entornos de Cloud Composer. Por ejemplo, puedes nombrar a estas redes composer-shared-vpc-1, composer-shared-vpc-2, etcétera.

PSC is the default connectivity type for environments in Cloud Composer 2 (when you create an environment in Google Cloud console), and it does not use VPC peering quotas (your environment's cluster still [uses VPC quotas](/composer/docs/composer-2/configure-private-ip#requirements)).\n\nFor more information, see\n[Configure Private Service Connect](/composer/docs/composer-2/configure-private-service-connect).\n\nQuotas for VPC, subnet and forwarding rules\n-------------------------------------------\n\nCloud Composer and GKE services use VPC peerings to\nestablish connections between the\n[components of Cloud Composer environments](/composer/docs/composer-2/environment-architecture)\n(Customer Project and Tenant Project) and between a GKE\ncluster and a GKE Control Plane.\n\nIf your project has a large-scale network configuration, such as one with\nhundreds of networks and many VPC peerings configured, then when you try to\ncreate new Cloud Composer environments, the operations might fail\nbecause of VPC, subnet or forwarding rules quota errors.\n\nThe errors that you might encounter are:\n\n- The maximum number of VPC peerings per single VPC network is reached.\n\n The default quota for a number of VPC peerings within a single VPC is 25\n (unless you request an increase of this quota).\n- The maximum number of primary and secondary subnet IP ranges is reached.\n\n The quota for this parameter is 400.\n- The maximum number of forwarding rules in the peering group for Internal TCP/\n UDP Load Balancing is reached.\n\n The quota for this parameter is 175.\n\nFor more information about default quotas for VPCs in Google Cloud, see\n[Quotas and limits](/vpc/docs/quota#vpc-peering).\n\nAbout large-scale networks for Cloud Composer environments\n----------------------------------------------------------\n\nTo overcome challenges related to these limits, you can organize your\nCloud Composer environments into several VPC networks connected to\nyour main/backbone VPC as it is described in the following sections.\n\nThis solution is applicable to Shared VPC and non-Shared VPC scenarios.\n\nLarge-scale network setup in a non-Shared VPC scenario\n------------------------------------------------------\n\nTo create a large-scale network setup for Cloud Composer:\n\n1. [Create a backbone VPC network](/vpc/docs/create-modify-vpc-networks#create-custom-network).\n This network acts as a hub for individual VPC networks that host\n Cloud Composer environments.\n\n2. [Create dedicated VPC networks](/vpc/docs/create-modify-vpc-networks#create-custom-network) for\n Cloud Composer environments. You can combine several\n Cloud Composer environments into one VPC network. For example,\n you can name these networks `composer-vpc-1`, `composer-vpc-2`, and so on.\n\n3. Establish connectivity between Cloud Composer environment VPC\n networks and the backbone VPC by\n [creating HA VPN tunnels](/network-connectivity/docs/vpn/how-to).\n\n| **Note:** The recommended way of configuring VPC network is to use custom mode when creating subnets.\n\nLarge-scale network setup in a Shared VPC scenario\n--------------------------------------------------\n\nTo solve the network peering limits issue in a Shared VPC networks, organize\nyour Cloud Composer environments into several projects and VPC\nnetworks connected to one backbone VPC.\n\nTo create a large-scale Shared VPC network setup for Cloud Composer:\n\n1. In the host project,\n [create a backbone VPC network](/vpc/docs/create-modify-vpc-networks#create-custom-network).\n This network connects individual VPC networks for service projects running\n Cloud Composer environments.\n\n2. In the host project,\n [create VPC networks](/vpc/docs/create-modify-vpc-networks#create-custom-network)\n for Cloud Composer environments. For example, you can name these\n networks `composer-shared-vpc-1`, `composer-shared-vpc-2`, and so on.\n\n3. Establish connectivity between these VPC networks and the backbone VPC\n network by manually\n [creating HA VPN tunnels](/network-connectivity/docs/vpn/how-to).\n\n4. Configure Cloud Composer environments\n [in the Shared VPC setup](/composer/docs/composer-2/configure-shared-vpc).\n\n| **Note:** The recommended way of configuring VPC network is to use custom mode when creating subnets.\n\nWhat's next\n-----------\n\n- [Configure Shared VPC](/composer/docs/composer-2/configure-shared-vpc)\n- [Create an environment](/composer/docs/composer-2/create-environments)"]]
