Revolutionizing Container Ingress: Automated Networking for Large-Scale Deployments
Managing containerized applications at scale often means battling a complex web of networking configurations. For platform teams overseeing services on container orchestration systems, the traditional approach to ingress networking can become a major bottleneck. Every time a new application is deployed, teams must manually provision and connect load balancers, security certificates, firewall rules, and security groups. Keeping all these pieces of infrastructure in sync as services grow or update slows down deployment velocity and increases the risk of configuration errors across the organization.
A new approach has been introduced to solve this problem: an account-level resource that simplifies ingress networking for containerized workloads. This solution dynamically provisions and manages the necessary infrastructure automatically, creating a clear separation of responsibilities between teams.
Platform teams are no longer forced to handle the intricate networking setup for every single service. Instead, they create and configure a central gateway once, defining organizational networking standards—such as subnets, security groups, TLS certificates, listener settings, and web application firewall (WAF) rules—in a single place. They then link this gateway to the container clusters their teams use.
Application developers, on the other hand, no longer need networking expertise to expose their services. They simply opt their service into the gateway by adding a connector parameter when creating or updating the service. The system automatically provisions all the required per-service resources: an SSL certificate, a unique web address, routing rules, target groups, and a strict security group that only allows inbound traffic from the load balancer.
This new feature offers host-based routing and allows up to 25 services to share a single load balancer, significantly optimizing infrastructure costs. The system manages the entire lifecycle of the underlying infrastructure. It provisions the first load balancer when a service connects, adds more load balancers as capacity is reached, and removes them entirely when they are no longer needed. The moment provisioning finishes, each service receives a unique DNS hostname, providing a ready-to-use endpoint for traffic.
Behind the Scenes
When a service is deployed, the system evaluates the gateways linked to its cluster and connects to every compatible one. A gateway is considered compatible if its access settings match the service’s configuration, it operates in the same network environment, and it covers all the required availability zones. The service is then assigned to a load balancer with available capacity, and all per-service resources are created.
The system handles common operational scenarios automatically. During redeployments, it re-evaluates gateway associations, ensuring services connect to newly added gateways and disconnect from ones that have been removed. If a service is deleted, the system automatically disconnects it from all gateways, removes the routing rules, and cleans up all per-service resources. If that service was the last user of a shared load balancer, the load balancer is deprovisioned as well.
Important Considerations
There are a few key details to keep in mind when using this automated ingress solution. It works with the awsvpc network mode across all compute types, including EC2, Fargate, and managed instances. However, the service’s availability zones must be a subset of the gateway’s zones.
Capacity planning is also crucial. There is a default quota limit on how many load balancers the system can scale up to. If this limit is reached and no load balancer has available capacity, new deployments will fail. Additionally, organizations can monitor traffic using standard cloud monitoring tools, tracking metrics per service or across the shared load balancer.
Availability and Cost
This new feature is available in all commercial regions where the underlying container service is offered. There is no additional charge for using the automated gateway feature itself. Organizations only pay for the underlying infrastructure provisioned in their own accounts when services connect, including load balancer fees, monitoring costs, certificates, and data transfer charges.
Frequently Asked Questions
Q: Who is responsible for managing the networking configuration?
A: Platform teams are responsible for setting up the central gateway and defining the organizational networking standards. Application teams are not required to manage any of the underlying infrastructure.
Q: Do application developers need deep networking knowledge to use this feature?
A: No. Developers simply add a connector parameter to their service definition. The system handles the provisioning of certificates, DNS hostnames, and security rules automatically.
Q: What happens to the infrastructure when a service is deleted?
A: The system automatically disconnects the service from all gateways, removes the routing rules, and cleans up all per-service resources. If the deleted service was the last to use a shared load balancer, that load balancer is also removed.
Q: Is there an extra cost for using this automated ingress solution?
A: No, there is no additional fee for the feature itself. Users only pay for the standard AWS resources generated as a result of the automated provisioning, such as load balancers and certificates.
Q: How does the system handle updates to the network configuration?
A: Platform teams can update the gateway settings, and during the next service deployment, the system will re-evaluate the gateway associations to ensure services are connected to the correct, up-to-date network configuration.
Conclusion
By introducing a centralized, automated approach to ingress networking, this new resource completely eliminates the manual bottleneck that has long plagued large-scale container deployments. It empowers platform teams to enforce security and networking standards once, while giving application developers the freedom to deploy services instantly without needing infrastructure expertise. Through dynamic load balancing, automatic resource cleanup, and cost-optimized sharing, this solution enables organizations to achieve faster deployment speeds, fewer configuration errors, and greater overall efficiency at scale.
