Amazon EC2 vs Dagger

Amazon EC2 provides resizable, secure compute capacity as virtual servers in the cloud. It offers over 1,000 instance types across Intel, AMD, and Arm processors for workloads including web and enterprise applications, high-performance computing, machine learning, SAP, Windows, and macOS. EC2 Auto Scaling can add or remove instances under dynamic or predictive policies. Instances can use persistent block storage through Amazon EBS and shared file storage through Amazon EFS; the service also provides a Query API and AWS SDKs. AWS says its Nitro System moves virtualization functions to dedicated hardware and isolates customer workloads. EC2 appears in AWS’s compliance program scope, though customers remain responsible for applicable compliance requirements. AWS states a 99.99% availability SLA commitment for each Region. Billing is per instance-hour or per second depending on instance type and operating system; eligible per-second use has a 60-second minimum. New AWS customers can receive up to $200 in credits, and the free plan lasts six months after account creation. The T4g free trial has monthly hour limits and surplus CPU credits can incur charges.

Dagger is a software stack for continuous integration built around an API, executable code, and a portable DAG execution engine. Pipeline logic can run locally or in Dagger Cloud, with automatic caching and end-to-end tracing. Cloud Checks connect a GitHub repository to Dagger Cloud and run checks on Cloud Engines after events such as pushes or pull requests, without a CI workflow file. Official modules cover testing, linting, formatting, type checking, browser tests, and Helm chart validation, and can be extended in a user's preferred language. The CLI has installation instructions for macOS, Linux, and Windows, and the documentation includes a self-hosting guide. Individual is free and allows one user, 1,000,000 monthly events, one month of run history, and community support. Team costs $50 a month after a two-week trial, for up to 10 users, 10,000,000 monthly events, one year of run history, and email support. Enterprise pricing is custom; SSO and managed single-tenant deployment are contact items. The site links to security and compliance information.
