What is Golem

Golem is an open source serverless computing platform that orchestrates and executes any software packaged into WebAssembly components.

Golem’s transparent durable execution ensures that components execute reliably, even in the presence of faults, restarts, updates, and transient failures.

Golem lets you build and deploy reliable distributed systems with simple code.

Example Use Cases

Durable computing guarantees your business logic executes completely, even in the presence of updates and infrastructure failures.

From workflows to process automation and microservice orchestration, Golem gives you effortless and flawless reliability.

Traditional serverless can’t be used to implement a checkout API, because implementing checkout requires coordinating state changes across many different systems, and this coordination must happen in a reliable way.

With Golem, implementing checkout is as simple as writing ordinary code with libraries you already know and love.

Golem will execute the checkout logic reliably, even in the presence of faults, restarts, updates, and transient failures, like cloud flakiness.


async function checkout(user, cart,paymentDetails, shippingAddress) { 
    try { 
        if (!(await checkAndReserveInventory(cart))) { 
            throw new Error("Inventory issue"); 
        }

        if (!user.isAuthenticated) { 
            await authenticateUser(user); 
        }

        const paymentInfo = paymentDetails || 
            (await getPaymentInformation(user));

        if (!(await processPayment(paymentInfo, cart.totalAmount))) {
            throw new Error("Payment issue");
        }

        const shippingDetails = 
            await generateShippingLabelAndTracking(shippingAddress, cart); 

        if (!(await dispatchOrderForFulfillment(cart, shippingDetails))) {
            throw new Error("Fulfillment issue");
        }

        await Promise.all([
            sendConfirmationEmail(user.email, cart, shippingDetails), 
            updateInventory(cart) 
        ]);

        return { success: true, message: "Checkout successful" }; 
    } catch (error) {
        console.error("Checkout failed:", error); // Rollback logic could be added here
    return { success: false, message: error.message }; 
    }
}

Robust

Golem automatically applies customizable retry policies to all recoverable failures, ending cloud flakiness once and for all.

Serverless

Golem lets you focus on business logic, and uses standards like OpenAPI to create APIs for your workers automatically.

Stateful

Golem automatically preserves worker state between requests, regardless of failures, reducing the need for databases.

Transactional

Golem brings transactions to your business logic, guaranteeing exactly-once semantics, even in the presence of failures.

Composable

Why Golem

Durable computing guarantees your business logic executes completely, even in the presence of updates and infrastructure failures.

From workflows to process automation and microservice orchestration, Golem gives you effortless and flawless reliability.

Many distributed systems must be highly reliable, executing critical updates across many systems in a way that is fault-tolerant. To achieve this level of reliability in the cloud, developers often adopt event-driven architectures powered by fault-tolerant durable queues. These architectures deliver mission-critical reliability, but they require high skill and add complexity.
‍
Golem solves the problem at the level of infrastructure, which radically simplifies code for developers. All software components deployed on Golem are automatically executed transactionally, with no changes or SDK required, even in the presence of faults, restarts, updates, and transient failures.
‍
Golem gives you high reliability with simple code.

Serverless computing simplifies building modern cloud systems, by abstracting away infrastructure and allowing developers to focus on business logic. In serverless, the platform automatically creates and manages workers, executing code in response to requests.

Golem improves serverless by introducing stateful workers that run indefinitely (not just for a single request) and reliable worker-to-worker communication. Combined with transparent durable execution, Golem allows developers to build any distributed system with serverless

WASM is a new way to package cloud applications that is portable across platforms, secure, and performant. With the WASM component model, code can natively and performantly call other code written in other languages, without the boilerplate and overhead of HTTP or gRPC.

Golem has a sophisticated custom executor for WASM components that provides automatic and transparent durability, which lets developers build highly reliable and scalable distributed systems with simple code, in any language and with any tech stack
