## What it is
PaaSTA is an open-source, distributed platform-as-a-service from Yelp for building, deploying, and monitoring containerized services on Kubernetes. It provides a simplified declarative schema so teams can describe services without hand-writing Kubernetes YAML, while wiring up monitoring, logging, service discovery, and autoscaling.

## Use cases
- deploy dockerized services to kubernetes without writing yaml
- self-host a platform as a service for my organization
- run production microservices with built-in monitoring and alerting
- automate continuous deployment of services
- autoscale services based on prometheus metrics
- manage nightly batch jobs alongside long-running services
- simplify service configuration for multiple infrastructure tools

## When to choose
- you run many microservices on kubernetes and want an opinionated, batteries-included PaaS
- your teams should not need to learn raw Kubernetes YAML
- you want integrated monitoring, logging, service discovery, and autoscaling from one declarative config
- you already use or can adopt Docker, Kubernetes, Sensu, SmartStack/Envoy, and Tron

## When to avoid
- you deploy only a handful of simple apps where plain Kubernetes manifests or a small tool suffice
- you cannot provide the substantial underlying infrastructure PaaSTA requires
- you want a fully unopinionated platform you can shape freely
- your stack is not Linux/Docker/Kubernetes based

## Facets
- artifact type: service
- maturity: stable
- function: deployment, container-orchestration, monitoring, ci-cd, microservices, scheduling, service-discovery
- domain: cloud-computing, microservices, infrastructure-as-code, self-hosted
- platform: python, self-hosted
- tags: paas, platform-as-a-service, yelp, service-deployment, declarative-config, autoscaling, devops, containers, docker, kubernetes, linux
