vHive v1.2

Added

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 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.

Changed

• 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.

Fixed

• CI pulls the latest binaries from git-lfs when running tests on self-hosted runners.

vHive v1.1

Added

• Created a CI pipeline that runs CRI integration tests inside containers using kind.
• [Beta] Added a developer image that runs a vHive k8s cluster in Docker, simplifying vHive development and debugging. Currently, only single-node clusters are supported.
• 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 *.md files.

Changed

• Use replace pragmas instead of Go modules.
• Bump Go version to 1.15 in CI.
• Deprecated Travis CI.

Fixed

• Fixed the vHive cluster setup issue for clusters with >2 nodes issue.

vHive v1.0

The first release of the vHive open-source framework for serverless experimentation.

Features:

• Function-as-a-Service (FaaS) programming model with Knative

• Cluster infrastructure support with Kubernetes integration

• Firecracker MicroVM hypervisor support

• MicroVM snapshotting: both vanilla Firecracker snapshots and advanced REcord-And-Prefetch (REAP) snapshots that we describe in our ASPLOS'21 paper (extended abstract, full paper).

See the paper for details.
