- Bumped Containerd to v1.6, Knative to v1.4, Go to v1.18, Kubernetes to v1.23, Istio to 1.12, protoc to 3.19, runc to 1.1.
- Support Ubuntu 20 as the host OS, Ubuntu 18 support dropped.
- Added support for gVisor MicroVMs, as an alternative to Firecracker.
- Added vSwarm, a suite of representative serverless workloads. Currently, in a beta testing mode.
- Added Python and Go tracing modules and an example showing its usage. Moved to vSwarm.
- Added Golang and Python storage modules, supporting AWS S3 and AWS ElastiCache. Moved to vSwarm.
- Added self-hosted stock-Knative runners on KinD,
see
scripts/self-hosted-kind.
- Workload stdout/stderr is not directly redirected to vhive stdout/stderr anymore
but is printed by vhive via
logrus.WithFields(logrus.Fields{"vmID": vmID}). - Moved the CRI non-Firecracker tests to self-hosted stock-Knative runners.
- Added 2 chained-functions microbenchmarks, synchronous and asynchronous, that use Knative Serving and Eventing, correspondingly. Tracing is fully supported for Serving function composition, partially supported for Eventing function composition.
- Added documentation on vHive benchmarking methodology for arbitrary serverless deployments.
- Added documentation for adding benchmarks to vHive.
- Added Knative Eventing Tutorial: documentation and example.
- Added a Go module for tracing using zipkin.
- Improved CI troubleshooting: CRI test logs are now stored as GitHub artifacts.
- Added script to (re)start vHive single node cluster in a push-button.
- Added a linter for hyperlink checking in markdown files.
- Bumped Containerd to v1.5.2.
- Bumped Knative to v0.23.0.
- Bumped Go to v1.16.4.
- Frozen Kubernetes at v1.20.6-00.
- Simplified Go dependencies management by refactoring modules into packages.
- Fixed stock Knative cluster startup.
Features for performance analysis
- Zipkin support added for tracing and breaking down latencies in a distributed vHive setting (e.g., across Istio and Knative services). More info here
- [beta] Added a profiler that collects low-level microarchitectural metrics, using the Intel TopDown method. The tool aims at studying the implications of multi-tenancy, i.e., the VM number, on the the tail latency and throughput.
Features for benchmarking at scale and multi-function applications
- Added cluster-local container registry support to avoid DockerHub bottleneck. Contributed by @amohoste from ETH Zurich.
- [alpha] Added Knative eventing support using In-Memory Channel and MT-Channel-broker. Integration tests and Apache Kafka support coming soon.
- Added support for MinIO object store (non-replicated, non-distributed). More info here
Other
- vHive now also supports vanilla Knative benchmarking and testing (i.e., using containers for function sandboxes). More info here.
- Bumped up the Firecracker version to v0.24 with REAP snapshots support.
- Bumped up all Knative components to version v0.21.
- MicroVMs have network access to all services deployed in a vHive/k8s cluster and the Internet by default, using an automatically detected, or a user-specified, host interface.
- CI pulls the latest binaries from git-lfs when running tests on self-hosted runners.
- Created a CI pipeline that runs CRI integration tests inside containers using kind.
- Added a developer image that runs a vHive k8s cluster in Docker, simplifying vHive development and debugging.
- Extended the developers guide on the modes of operation, performance analysis and vhive development environment inside containers.
- Added a slide deck of Dmitrii's talk at Amazon.
- Added a commit linter and a spell checker for
*.mdfiles.
- Use replace pragmas instead of Go modules.
- Bump Go version to 1.15 in CI.
- Deprecated Travis CI.
- Fixed the vHive cluster setup issue for clusters with >2 nodes issue.
