Platforms Thoughtworks Technology Radar 35. actions-runner-controller Assess actions-runner-controller is a Kubernetes controller that operates self-hosted runners for GitHub Actions on your Kubernetes cluster. With this tool you create a runner resource on Kubernetes, and it will run and operate the self-hosted runner. Self-hosted runners are helpful in scenarios where the job that your GitHub Actions runs needs to access resources that are either not accessible to GitHub cloud runners or have specific operating system and environmental requirements that are different from what GitHub provides. In those cases where you have a Kubernetes cluster, you can run your self-hosted runners as a Kubernetes pod, with the ability to scale up or down hooking into GitHub webhook events. actions-controller-runner is lightweight and scalable. 36. Apache Iceberg Assess Apache Iceberg is an open table format for very large analytic data sets. Iceberg supports modern analytical data operations such as record-level insert, update, delete, time-travel queries, ACID transactions, hidden partitioning and full schema evolution. It supports multiple underlying file storage formats such as Apache Parquet, Apache ORC and Apache Avro. Many data-processing engines support Apache Iceberg, including SQL engines such as Dremio and Trino as well as (structured) streaming engines such as Apache Spark and Apache Flink. Apache Iceberg falls in the same category as Delta Lake and Apache Hudi. They all more or less support similar features, but each differs in the underlying implementations and detailed feature lists. Iceberg is an independent format and is not native to any specific processing engine, hence it’s supported by an increasing number of platforms, including AWS Athena and Snowflake. For the same reason, Apache Iceberg, unlike native formats such as Delta Lake, may not benefit from optimizations when used with Spark. 37. Blueboat Assess Blueboat is a multitenant platform for serverless web applications. It leverages the popular V8 JavaScript engine and implements commonly used web application libraries natively in Rust for security and performance. You can think of Blueboat as an alternative to CloudFlare Workers or Deno Deploy but with an important distinction — you have to operate and manage the underlying infrastructure. That said, we recommend you carefully assess Blueboat for your on-prem serverless needs. 38. Cloudflare Pages Assess When Cloudflare Workers was released, we highlighted it as an early function as a service (FaaS) for edge computing with an interesting implementation. The release of Cloudflare Pages last April didn’t feel as noteworthy, because Pages is just one in a class of many Git-backed site-hosting solutions. It did have continuous previews, a useful feature not found in most alternatives. Now, though, Cloudflare has more tightly integrated Workers and Pages, creating a fully integrated Jamstack solution running on the CDN. The inclusion of a key-value store and a strongly consistent coordination primitive further enhance the attractiveness of the new version of Cloudflare Pages. © Thoughtworks, Inc.
