Container App environment
Microsoft Learn describes a Container Apps environment as a secure boundary around one or more container apps and jobs. The runtime manages the environment by handling OS upgrades, scale operations, failover procedures, resource balancing, shared networking, and observability settings for the workloads that run inside it.

Cosmos DB serverless account
Cosmos DB serverless account is a Cosmos DB account created with the serverless capacity mode so databases and containers are billed by consumed request units and storage. It turns serverless billing into an account-level design choice rather than a per-container toggle. You see it when teams create accounts for prototypes, seasonal apps, low-duty-cycle workloads, or services with uncertain early demand. The production check is whether the account capacity mode supports the API, scale target, compliance need, and migration plan. Document the decision in code, templates, metrics, and runbooks.

Cosmos DB serverless
Cosmos DB serverless is the Cosmos DB capacity mode that bills for request units consumed and storage used instead of pre-provisioned RU/s. It lets intermittent or unpredictable workloads use Cosmos DB without reserving throughput all day. You see it when a new account is created, a workload has bursty usage, or a team compares serverless with provisioned throughput. The production check is whether consumption billing, throughput limits, regional design, and workload shape fit the production objective. Document the decision in code, templates, metrics, and runbooks.

Autoscale throughput
Autoscale throughput is Azure Cosmos DB’s way to adjust request-unit capacity for a database or container as traffic changes. In plain terms, you set a maximum RU/s value, and Cosmos DB scales within that range instead of forcing you to pick one fixed manual throughput number. It is useful for workloads with bursts, uneven schedules, or.

Target port
A target port tells Azure Container Apps where to deliver traffic inside your container. Public or internal ingress may expose an endpoint, but the app still has to listen on a specific port. If the container listens on 8080 and ingress targets 80, users may see timeouts, failed probes, or gateway errors. The setting is small, but it is often the difference between the app being deployed and the app being reachable. It should match the application startup command, Dockerfile, framework port, and health probes.

Cosmos DB provisioned throughput
Cosmos DB provisioned throughput means the request-unit-per-second capacity reserved for a database or container, either manually or with autoscale behavior in Azure Cosmos DB. In plain English, it is the thing developers and operators check when they need to understand how data access really works. It connects the application model to capacity planning, throttling prevention, RU allocation, cost control, and predictable performance for operational workloads. For a production team, it turns vague database talk into a specific thing to inspect in the portal, SDK code, templates, metrics, and incident notes.
