Releasing software is treacherous — let us help. Caching keeps the internet from being painfully slow, but fighting powerful caching layers can be difficult. Good release engineering practices enable rapid iteration while operating in a safe environment. Netlify's features include atomic deploys, asset fingerprinting, instant cache invalidation, Continuous Deployment, and instant rollback, which ease the whole release process without any headache. By versioning assets and markup, Netlify ensures globally consistent versions of sites, minimizing the risk involved in deploying and testing new site versions. Instant rollbacks allow developers to rapidly iterate on the site without fear of bringing down their corner of the web. With a network of nodes, Netlify's CDN invalidates caching layers, ensuring a consistent version of the site globally. By tying instant cache invalidation, atomic deploys, and immediate rollback into a continuous delivery platform, Netlify empowers developers to focus on building their site rather than worrying about breaking it.
