Monolith vs Microservices (In Simple Terms)

How Background AI Agents Get Permission

This matters because not every AI agent is a person sitting in front of a chat window. In this episode, Satish uses a simple real-life example first, then turns the idea into a practical technical mental model for engineers and curious builders. In Simple Terms with Satish: daily tech trends explained simply, with enough technical depth for builders. Production note: This episode uses authorized synthetic narration based on Satish's own voice. The topic, script, and final editorial approval are by Satish. Engineer notes: Exact technical references: - Official MCP extension: `io.modelcontextprotocol/oauth-client-credentials`. - The extension is intended for background services, CI/CD jobs, server-to-server integrations, and daemon processes. - Supported auth patterns include standard client credentials with `client_id` and `client_secret`, and JWT bearer assertions from RFC 7523. - Remote MCP servers still act as protected resources and should validate issuer, audience or resource binding, expiry, and scope. - Related implementation surfaces include protected resource metadata, auth provider support in MCP SDKs, and extension capability negotiation during initialize.

OpenTelemetry for AI Agent Traces

This matters because AI agents are starting to behave less like simple chatbots, and more like small distributed systems. In this episode, Satish uses a simple real-life example first, then turns the idea into a practical technical mental model for engineers and curious builders.

MCP Authorization for AI Agent Tools

This matters because AI agents are not only answering questions anymore. They are starting to use tools that can read data, search systems, create records, update files, or trigger workflows. In this episode, Satish uses a simple real-life example first, then turns the idea into a practical technical mental model for engineers and curious builders.

Engineer notes: Exact technical references: - MCP Authorization specification version: 2025-11-25. - MCP servers act as OAuth resource servers when protected over HTTP. - MCP servers use OAuth 2.0 Protected Resource Metadata from RFC 9728. - Related OAuth standards include OAuth 2.1, RFC 8414 authorization server metadata, RFC 7591 dynamic client registration, RFC 8707 resource indicators, and PKCE. - Relevant implementation terms: `authorization_servers`, `resource_metadata`, `WWW-Authenticate`, `resource`, `insufficient_scope`, `readOnlyHint`, `destructiveHint`, `idempotentHint`, and `openWorldHint`. - Security checks to test: issuer validation, audience/resource binding, expiry, signature or introspection, scope, redirect URI validation, step-up retries, and token passthrough rejection.

Prompt-Injection Defense for AI Agents

Hello, and welcome to In Simple Terms with Satish. Today we are talking about prompt-injection defense for AI agents. This matters because AI agents now read real-world information and use real tools, so a hidden instruction in a page, email, document, or tool response can become dangerous. In this episode, Satish uses a simple real-life example first, then turns the idea into a practical technical mental model for engineers and curious builders.

Monolith vs Microservices (In Simple Terms)

Monolith vs Microservices is one of the most common decisions in system design—but it’s often misunderstood. In this episode, we go beyond definitions and walk through a real system flow: what happens when a user places an order, and how that same request behaves differently in a monolith versus a microservices architecture. We cover: * Internal vs network communication * Single deploy vs independent services * Why microservices introduce complexity * When each architecture makes sense If you’re learning system design or building applications, this episode will help you think like an architect—not just memorize concepts. system design, microservices, monolith architecture, software architecture, backend systems, distributed systems, tech explained, software engineering, api design, system scalability
