Remote procedure call
A remote procedure call is a communication technique in which a program invokes an operation executed in another process or system, typically through an interface resembling a local procedure call.
Server-Side WebAssembly
A remote procedure call is a communication mechanism that lets a program invoke a function or procedure on another system.
- How it is used
- Uses RPC to connect wasmCloud components dynamically across hosts through NATS and wRPC.
- How deep it goes
- Defines RPC and explains its wasmCloud architecture, but stops short of detailing the wRPC protocol internals.
- Examples
- Demonstrates an HTTP component, a linked HTTP server capability, a wadm manifest, NATS, and a curl response.
- What you can do after
- Evaluate how wasmCloud components communicate locally or across hosts through configured runtime links.

Akka in Action, Second Edition
A remote procedure call is a communication mechanism that invokes an operation in another process or system as though it were a local procedure.
- How it is used
- Frames RPC as a traditional scaling mechanism whose interaction with databases and threads raises complexity.
- How deep it goes
- Explains blocking database RPCs and introduces Akka gRPC interfaces, while deferring client-side treatment.
- Examples
- Uses a scaling business chat application, DAO database calls, and a traditional-versus-actor comparison table.
- What you can do after
- Apply it via Akka gRPC to create a server-side port after defining a .proto interface.

Elixir in Action, Third Edition
A remote procedure call, or remote function call, is an invocation of an operation on another process or machine presented as though it were a local function call.
- How it is used
- Supports result-bearing calls and multi-node coordination inside distributed Elixir systems.
- How deep it goes
- Explains invocation, returned results, message costs, and the :rex implementation, while deferring broader distributed-system challenges.
- Examples
- Demonstrates Kernel.abs(-1) executed on node2 through an IEx :rpc.call/4 expression.
- What you can do after
- Apply it via :rpc.call/4 to execute functions remotely and retrieve results from one or multiple nodes.

API Design Patterns
A remote procedure call is a mechanism for invoking a procedure or method whose execution occurs on another computer or process.
- How it is used
- Deploys APIs around explicit actions, especially independent operations such as forecasting weather, encrypting data, or sending email.
- How deep it goes
- Defines invocation style and contrasts stateless and stateful fit without detailing transport or implementation internals.
- Examples
- Uses weather forecasting, encryption, email, and flight-booking methods to illustrate action-oriented API naming.
- What you can do after
- Evaluate whether an action-oriented RPC interface fits stateless functionality or stateful resource operations.

Advanced Algorithms and Data Structures
A remote call is an invocation of an operation provided by a component running outside the caller's local process or machine.
- How it is used
- Frames communication with externally hosted services in distributed e-commerce order processing.
- How deep it goes
- Explains addressing spaces, latency, and failure modes, but stops short of detailing recovery strategies.
- Examples
- Uses retailer inventory, shop.order, HTTP timeouts, crashed servers, and order-processing workflows.
- What you can do after
- Evaluate distributed workflows by accounting for latency, unreachable services, timeouts, and uncertain operation outcomes.
