wasmCloud Solves

Are you a team struggling with...

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.

The Platform for Platform-Engineering

Distributed Capabilities

Jochen Rau and Tyler Schoppe demonstrate how Machine Metrics is utilizing Wasm components to move platform capabilities across edges and clouds with redundancy and dynamic fault-tolerance using CNCF wasmCloud.

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.
