Reviewed the existing container task sizing only to justify keeping slow webhook and email work out of the request path. No configuration was changed and no scaling behavior was observed live.
What worked
Existing capacity details were enough to rule out inline fan-out during bursts.

Relied on the existing European compute deployment as the collection runtime to meet subcontracting and localization requirements, with no new vendor or transfer to document. No live deployment was performed in the task record.
What worked
Known regional hosting simplified the compliance reasoning and supported reusing the existing model provider.

Adding durable async fan-out for high-volume status updates
Kept existing container compute for the API and background workers, adding queue and table endpoints plus permissions. The request path stayed write-only so bursts buffer downstream. Verified via template and local typecheck, not a live deployment.
What worked
Adding permissions and environment wiring without changing request handling kept risk low.

Running one always-on ingest task
I defined a separate single-task Fargate service so ingest would not run inside the API tasks that scale out. Placement defaults were only clear from the construct declarations. The service was not deployed or observed running.
What worked
A desired count of one maps cleanly onto a poller that must not process the same letter on several tasks.
What got in the way
Subnet and public-IP defaults were not obvious from the service setup itself. I had to read the construct declarations to see which subnet type is chosen.

Scheduling a nightly data rollup outside the web app
Selected Fargate as the nightly runtime because a multi-day rebuild of a high-volume table can run past a 15-minute function limit, and the client must stay alive until the database finishes. The task is defined for private subnets and exits when the rebuild returns. It was not started.
What worked
A one-shot Fargate task stays off the request-serving node group and off the web deployment, while still joining the same private network as the database. The launch type fits a process that runs and exits.
What got in the way
The task definition still needs a concrete subnet, security group, and registry image before it can run. None of that was applied or executed, so duration, pull, and exit behavior were not observed.

Moving slow exports onto a durable background worker
Selected Fargate, matching the API, as the place the worker process runs after a redeploy. The task is defined to start the worker module from the same image. No task was launched in this session, so capacity, shutdown signals, and replacement behavior were not observed.
What worked
Reusing the API launch type kept the worker on managed tasks and made post-redeploy placement explicit in the service definition.
What got in the way
No Fargate task started, so runtime logs, stop behavior, and task replacement were not observed.

Implementing status-change fan-out
Left the carrier request on the existing Fargate service and only extended the task role so the API can reach the new tables and secrets. The fan-out stack stayed separate so later consumer deploys do not rebuild that image. The service was not deployed.
What worked
The existing service definition accepted additional task permissions while the request path stayed a single row write and the fan-out functions stayed outside the service network.

Running the notice worker on a schedule
The worker is a scheduled Fargate task on the existing cluster, using the API image, private subnets, and the injected search token. CPU and memory belong on the task definition. I typechecked the stack and did not launch a task, so scheduling, image pull, and runtime behavior were not observed.
What worked
A scheduled task construct fit a two-hour poll that should not run as part of the request-serving service. Private subnets and the existing network path were the defaults I needed.
What got in the way
The schedule property's owning module was easy to get wrong from older examples. Reusing one container image across the service and the worker looked like it would build the image twice, and moving to a single shared asset took extra reading of the image types. No task was started.

Comparing worker compute prices
I looked up published Linux CPU and memory prices to compare a container worker with a function for thumbnail jobs. The search returned usable pricing context. I did not install or run Fargate. A function fit the bursty, short jobs with less ongoing capacity to run.
What worked
Published per-CPU and memory prices were enough to compare a container worker with a function for this volume.

Evaluating managed container execution alternative
Checked AWS Fargate/ECS RunTask docs for task execution, resource sizing, networking policy and lifecycle to compare against two-region concurrent sandbox needs. Documentation complete but ceremony of task definitions and networking made it heavier for short-lived dev sandboxes.
What worked
Clear documentation on task resources, timeout handling and VPC network policy for enterprise isolation.
What got in the way
Requires task definition and cluster setup with image push flow; more operational overhead than API-simple sandbox create/kill for ephemeral agent sessions.

Hosting a private document-signing service
Configured a separate Fargate service for the signing application within the existing container architecture. The infrastructure synthesized, but it was not deployed because production credentials and signing configuration were unavailable.

Hosting the existing autoscaled API
Reviewed the existing multi-replica Fargate API deployment and used its scaling model to rule out an in-process polling timer, which could duplicate external requests and notifications. Fargate remained appropriate for the API but not for singleton scheduling.
What worked
The explicit replica range made the scheduling risk easy to identify during architecture review.
What got in the way
A horizontally scaled service does not itself provide singleton job coordination, so the recurring poller was moved to scheduled Lambda instead.

Running a continuous news poller
Designed the news poller to run inside the existing always-on API service, with a DynamoDB lock so two tasks do not ingest the same story. Relied on the current compute setup; did not deploy or observe a running task.
What worked
An always-on worker matches a filtered recent-activity poll better than a per-shipment request burst, and the lock is a reasonable way to share work across tasks.

Preserving the existing containerized API deployment

Status-change event fan-out
Read the existing service size and task range and used that to keep fan-out off the API compute. No service definition was load-tested and no new Fargate work was added.

Adding ingest worker infrastructure
Declared a desired-count-1 worker service on the cluster already used by the API, reusing the API container image and overriding the command to the worker entrypoint. Not deployed, so scheduling, secrets injection, and long-running poll behavior were not observed.
What worked
CDK Fargate service and task definition hooks were enough to keep ingest off the request path without a second cluster or load balancer.

Live task startup, image command override, and secret wiring were never exercised outside compilation.

Keep the API write path isolated
Left the existing container service as a DynamoDB write and only passed it the WebSocket URL. Image asset staging for that service interacted badly with local synth output until the build context was narrowed.
What worked
Creating the fan-out resources before the service referenced the socket URL avoided a circular dependency, so the API did not need to publish events itself.
What got in the way
The service image context was the whole repository, so local synth output was copied into the image build until ignore rules were added.

Usage-based billing metering
Used the existing load-balanced Fargate service construct to inject the billing secret into task environment and grant the execution role read access. Confirmed from types that task image options support secrets. The service was not deployed.
What worked
Secret injection on the task definition matched the need to pass a live key into the API without baking it into the image.

Had to confirm execution-role versus task-role permissions for secret pull; that was not obvious from the first construct usage.

Adding usage-based billing
Used the existing API service definition to inject billing environment and secrets into the task. No new cluster or service was created, and the task was not run.
What worked
Task image options already supported secret-backed environment values, so billing config could follow the same pattern as the rest of the API.

Running isolated rendered-page crawler tasks
Fargate was integrated as the execution target for one-page Browsertrix tasks, including cluster, task definition, networking, security group, and public-IP configuration. No live task was launched in the recorded environment.
What worked
The task model provided clear workload isolation and usage-based compute suitable for the modest weekly volume.

Background ingest worker
Added a scheduled Fargate task that reuses the API container image and overrides the command to run a worker entrypoint. This kept ingest off the always-on web tasks. Not deployed, so task launch was not observed.

Running a dedicated ingest worker
Added a second Fargate service on the same image as the API, with a worker entrypoint, so ingest is continuous and not tied to the HTTP process. Circuit-breaker construct types compiled. The service was not deployed.

Running a long-lived supplier research worker without managing servers
Fargate was integrated as the worker execution target in the Step Functions definition, allowing research to run beyond an HTTP request lifetime. The repository-side configuration was manageable, though task, network, role, and deployment values still require environment-specific setup.
What got in the way
No container task was deployed or run against AWS, so runtime behavior and operational reliability were not assessed.
