Push model
A push model is a communication pattern in which a producer or system proactively sends data, work, or updates to recipients rather than waiting for each to request them.

A push model is an automation pattern in which a management system initiates connections and sends configuration to managed systems.
- How it is used
- Automates centralized configuration delivery when a management system must apply changes immediately to managed devices.
- How deep it goes
- Defines connection direction, agent requirements, protocols, and tool contrasts, but stops short of device-specific command configuration.
- Examples
- Uses Ansible over SSH or NETCONF and contrasts it with Terraform, Puppet, and Chef.
- What you can do after
- Apply it via Ansible by identifying the control node, managed devices, connection protocol, and configuration files involved.

Push-based programming is a style where data is delivered to consumers when it becomes available rather than being pulled on demand.
- How it is used
- Uses producer-driven delivery to handle arriving values without consumer polling.
- How deep it goes
- Defines push against pull, then works through EventEmitter subscriptions and a Proxy-based observable adapter.
- Examples
- Illustrates incoming chat messages, an EventEmitter-backed array, and a proxied array whose new values enter an observable pipeline.
- What you can do after
- Build it from scratch with EventEmitter-backed subscriptions, or adapt a pushable iterable using Proxy.
Logs and Telemetry
A push model is a data-delivery pattern in which the source sends data to a receiving service when the data becomes available.
- How it is used
- Uses event-driven delivery to move metrics to central or cloud services when polling would add latency or waste calls.
- How deep it goes
- Explains polling trade-offs, connection behavior, remote-write standardization, and Fluent Bit endpoint configuration.
- Examples
- Demonstrates local Prometheus and Grafana Cloud outputs using Fluent Bit metrics, TLS, credentials, endpoints, and labels.
- What you can do after
- Operate Fluent Bit remote-write outputs for local or cloud metric destinations.

A push model is a messaging consumption pattern in which the messaging system delivers available messages to a consumer automatically.
- How it is used
- Delivers available JMS messages to application code through an automatically invoked listener.
- How deep it goes
- Explains listener invocation, thread blocking trade-offs, and overload concerns without descending into listener-container internals.
- Examples
- Uses an OrderListener that receives TacoOrder objects from tacocloud.order.queue and displays them through KitchenUI.
- What you can do after
- Operate a Spring JMS listener that receives converted domain objects as messages become available.
