cloudNo. Heroku eliminated its free tier in 2022. The cheapest option is the Eco dyno at $5/month (0.5 GB RAM, sleeps after 30 minutes of inactivity); Basic dynos at $7/month stay always on (checked 2026-09-03).
Heroku is a fully managed PaaS owned by Salesforce: you deploy apps with git push, buildpacks handle the runtime, and managed Postgres, Redis and AI inference are available alongside 150+ add-ons — no infrastructure management required.

Cloud computing is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources that can be rapidly provisioned and released with minimal management effort. The NIST definition breaks it into five essential characteristics, three service models (SaaS, PaaS, IaaS) and four deployment models (public, private, community, hybrid). This guide explains each part and how to choose between them.
Serverless computing is a cloud service category where the customer provides application code or data and does not provision, deploy, or manage the underlying hardware or software resources. Functions as a Service (FaaS) is the core execution model: you upload a function and the platform runs it, scales it, and bills you only for actual execution time. This guide explains how serverless works, its benefits and trade-offs, the common anti-patterns, and when it is the right choice.
