July 2016 Summaries

Buildkite has improved its invitation email process by allowing any email address to work for invitations, whether or not it is linked to an existing account, thereby simplifying the process for both the inviter and invitee. Drawing inspiration from Basecamp 3, the emails are designed to have the reply-to address linked directly to the sender, with the sender's identity clearly displayed, along with a picture of the inviter. Additionally, Buildkite has integrated automatic email verification into the invitation process, reducing the need for separate verification steps. These changes aim to streamline the process of inviting teammates by minimizing email clutter and clicks, allowing users to focus on more critical tasks like building pipelines or engaging in leisure activities.

Buildkite enables teams to scale CI pipelines using AWS-based Buildkite Agent clusters, allowing for horizontal scaling based on build demand, exemplified by Shopify's use of 50,000 daily build jobs. To simplify setup, Buildkite developed the Elastic CI Stack for AWS, a pre-built CI/CD stack that provides an autoscaling build cluster within a user's AWS VPC. This stack supports parallelizing large test suites, running Linux-based projects, and executing AWS operations tasks, while integrating tools like Docker and CloudWatch. Users can create multiple stack instances for different needs, with internal examples including a pipeline uploader, a builder with cached resources, and autoscaling runner instances. The stack is open-source, allowing users to build custom AMIs and run tools locally, and a step-by-step setup guide is available for getting started.
