Create cloud services with Swift

Run performant services on Linux and deploy to the cloud

  • Performant With incredible memory efficiency, Swift operates without a garbage collector, running with predictable speed while using fewer resources.
  • Lightweight Swift has minimal warm-up operations, making it an ideal fit for running cloud services, which are often rescheduled onto virtual machines and containers.
  • Scalable Powering internet-scale cloud services that handle billions of requests a day, Swift is capable of running large production workloads.
Get Started

Low memory footprint. Massive performance.

Cultured Code migrated the services that support Things to Swift and saw a massive reduction in both cost and response time.

By leveraging Swift’s built-in features and server-oriented packages, they were able to thoroughly test and rapidly improve their customer experience.

Build & publish containers natively

Container images are the standard way to package cloud software today. Once you've packaged your server in a container image, you can deploy it on any container-based public or private cloud service, or run it locally using a desktop container runtime.

Swift Container Plugin allows you to build and publish container images for your Swift services in one streamlined workflow with Swift Package Manager.

Swift Container Plugin

Develop and deploy to the cloud

$ docker pull swift

Swift publishes official container images for multiple architectures, making it easy to develop on Linux and to deploy to production. Ready-to-use guides are available for deploying to environments like Kubernetes, AWS, GCP, Digital Ocean, and many others.
