AWS AppConfig

Two services in one crate:

• AppConfig (control plane, signing name appconfig) — applications, environments, configuration profiles, hosted versions, deployments, deployment strategies.
• AppConfigData (data plane, signing name appconfig, service name appconfigdata) — StartConfigurationSession + GetLatestConfiguration for runtime polling.

Both services share the same backing state.

Environments	CreateEnvironment, GetEnvironment, ListEnvironments, DeleteEnvironment
Configuration profiles	CreateConfigurationProfile, GetConfigurationProfile, ListConfigurationProfiles, DeleteConfigurationProfile
Hosted versions	CreateHostedConfigurationVersion, GetHostedConfigurationVersion
Deployments	StartDeployment, GetDeployment, ListDeployments
Deployment strategies	CreateDeploymentStrategy, ListDeploymentStrategies

Data-plane operations

Operation	Method / Path
StartConfigurationSession	POST /configurationsessions
GetLatestConfiguration	GET /configuration

Behavior notes

• Application/environment/profile IDs are 7-character hex; resources cascade-delete when the parent is removed (deleting an application removes its environments, profiles, hosted versions, and deployments).
• CreateHostedConfigurationVersion increments the parent profile's LatestVersionNumber automatically — pass any VersionLabel you want surfaced via GetLatestConfiguration.
• StartDeployment is fast-forwarded — the returned deployment is already State: COMPLETE with PercentageComplete: 100. The event log records a single DEPLOYMENT_COMPLETED entry.
• ListDeploymentStrategies always includes the AWS-managed predefined strategies (AppConfig.AllAtOnce, AppConfig.Linear50PercentEvery30Seconds, AppConfig.Canary10Percent20Minutes).
• StartConfigurationSession accepts either resource IDs or names for ApplicationIdentifier / EnvironmentIdentifier / ConfigurationProfileIdentifier.
• GetLatestConfiguration rotates the polling token on each call (the SDK stores the new token for the next poll). Configuration is a base64-encoded blob; if no hosted version exists, the response is empty.
