Wasm-native
Orchestration
Build, manage, and scale Wasm apps
across any cloud, K8s, or edgeeven your own!
Idle Infrastructure?
Does scalability preparedness, unpredictable workloads and long cold starts leave you with inefficient infrastructure and ever-growing cloud costs?
Maintaining Apps?
Are developers patching the same vulnerabilities and managing updates and dependencies across 100's or 1,000's of apps? Do you have apps that fall behind your golden template?
Distributed Deployments?
Do you need to run your apps across cloud vendors? Close to your users? Multi-Region? On the Edge? On Prem? Disrupted, disconnected, intermittent or limited connectivity?
What is wasmCloud?
Fast-track the development, deployment, and orchestration of WebAssembly components
wasmCloud is an open source project from the Cloud Native Computing Foundation (CNCF) that enables teams to build polyglot applications composed of reusable Wasm components and run them—resiliently and efficiently—across any cloud, Kubernetes, datacenter, or edge.
Build
Faster Development Cycles
Leverage reusable, polyglot, Wasm components on a reliable, distributed platform.
Centrally Maintainable Apps
Reusable, version-controlled components empower platform teams to maintain thousands of diverse apps centrally.
Integrate with Existing Stacks
wasmCloud has first-tier support for Kubernetes, AWS, Azure, GCP, Jenkins, GitHub Actions, ArgoCD, Backstage, Chainguard, Databases, Messaging, and more.
Compose
Development Without Lock-In
Define application dependencies at runtime via contract driven interfaces leveraging different vendors across deployments, dev, QA, or prod.
Truly Portable Apps
Run the same Wasm application across operating systems and architectures—no new builds required. Linux, MacOS X, Windows, ARM, x86, and more.
Custom Capabilities
Easily extend the secure wasmCloud host at runtime to support custom dependencies, hardware, or business contracts.
Run
Scale-to-Zero with Zero Cold Starts
Sub-millisecond start times and vertical autoscaling means workloads scale to the demand.
Reliable, Fault-Tolerant Apps
Horizontal scaling with automated fail-over gives apps capability-level resiliency, reliability, and scalability.
Deploy Across Clouds
Close to your users, with local-first routing and at-most-once delivery, wasmCloud delivers cross-region, cross-cloud, and cross-edge capability-level resiliency to every deployment
Why use wasmCloud?
Productivity. Maintainability. Portability. Reusability. Availability. Security.
WebAssembly components are a finer-grained abstraction for application composition and a Wasm-specific orchestrator maximizes their full potential.
wasmCloud as a Platform
The Platform for Platform-Engineering
Elevating Serverless Platforms with Wasm
Vamsi Sangavarapu and Ritesh Rai of American Express explore how Wasm and CNCF wasmCloud are revolutionizing their enterprise multi-tenant Function-as-a-Service platform.
Wasm across Any Cloud, K8s, or Edge
Colin Murphy from Adobe and Douglas Rodrigues from Akamai discuss how they use CNCF wasmCloud to run WebAssembly across cloud services, Kubernetes clusters, and edges.
Distributed Capabilities: Wasm on the Factory Floor
Jochen Rau and Tyler Schoppe demonstrate how Machine Metrics is using CNCF wasmCloud to move platform capabilities across edges and clouds with redundancy and dynamic fault-tolerance.
