Scaling via competing consumers is a nice side benefit, not the reason to adopt events. Events as notifications decouple independent responsibilities in time (e.g., a shipment delivery triggering a webhook, SMS, and push notification separately from the delivery recording itself). Commands (instructions like DeliverShipment) differ from events (facts like ShipmentDelivered). Event sourcing is a separate concern about deriving state from a history of meaningful domain events, not about notifications or scale; recording generic CRUD-style updates as an event stream ('CRUD sourcing') is not real event sourcing. For simple request-response CRUD apps without independent workflows or integration boundaries, event-driven architecture can indeed be overkill. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What is the difference between a command and an event in event-driven architecture? A command invokes behavior, like DeliverShipment, and is an instruction typically handled by one consumer responsible for doing the work. An event is a statement of fact that already happened, like ShipmentDelivered, published by one source with zero, one, or many consumers who react independently without the publisher knowing who they are. _daily.dev surfaces architecture explainers like this for teams untangling commands from events in their own systems._ ### Is event sourcing the same thing as using events for notifications in a system? No, they serve different purposes. Events for notifications let independent parts of a system react to a fact, like sending a webhook or SMS after a shipment is delivered, decoupling responsibilities in time. Event sourcing instead stores the sequence of events as the source of truth, from which current or historical state is derived, which is useful when history and domain language genuinely matter. _Developers weighing event sourcing against simpler messaging patterns can track these distinctions on daily.dev._ ### What is CRUD sourcing and why is it considered a bad use of event sourcing? CRUD sourcing is when an event stream just records generic state changes like ShipmentCreated, ShipmentUpdated, ShipmentUpdated, rather than meaningful domain events such as Dispatched, ArrivedAtShipper, or Delivered. It is not real event sourcing because the events carry no domain language or history value, making it pointless complexity instead of a genuine source of truth. _daily.dev helps engineers spot anti-patterns like this before committing a team to event sourcing._ ## Similar posts on daily.dev - [\*\*Data-Driven vs Event-Driven Architecture: How to Pick the Right One\*\*](https://daily.dev/posts/data-driven-vs-event-driven-architecture-how-to-pick-the-right-one--hhq5msjoy) · SitePoint · 113 upvotes · 5 comments - [Patterns & Best Practices in Event-Driven Systems — Kogan.com Dev Blog](https://daily.dev/posts/patterns-best-practices-in-event-driven-systems-kogan-com-dev-blog-klr34bwfw) · Kogan.com · 44 upvotes · 2 comments - [Developers' tips for Event Sourcing & EDA](https://daily.dev/posts/developers-tips-for-event-sourcing-eda-9ezyc9slp) · Event Store · 0 upvotes · 0 comments - [Event Sourcing: You better Prevent long event streams](https://daily.dev/posts/event-sourcing-you-better-prevent-long-event-streams-ebtbewtn0) · We Are .NET · 0 upvotes · 0 comments --- Tags: [#architecture](https://daily.dev/tags/architecture) [View this post on daily.dev](https://daily.dev/posts/is-event-driven-architecture-overkill-for-most-apps--lfyebz9ps) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Is Event-Driven Architecture Overkill for Most Apps?","url":"https://daily.dev/posts/is-event-driven-architecture-overkill-for-most-apps--lfyebz9ps","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/is-event-driven-architecture-overkill-for-most-apps--lfyebz9ps"},"datePublished":"2026-10-04T13:08:04.378Z","dateModified":"2026-10-05T10:00:17.808Z","description":"Event-driven architecture is often misunderstood, and the confusion usually stems from conflating scaling, events-as-notifications, commands, and event...","image":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/7a1ff64051a6f83bf16b47035b34cfe3?_a=AQAEuop","thumbnailUrl":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/7a1ff64051a6f83bf16b47035b34cfe3?_a=AQAEuop","isAccessibleForFree":true,"articleSection":"CodeOpinion","inLanguage":"en","publisher":{"@type":"Organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180}},"author":{"@type":"Person","name":"Derek Comartin","url":"https://daily.dev/codeopinion","image":"https://lh3.googleusercontent.com/a-/AOh14GgoQapb7NmLN1TZ6L-UCxkRpDZ4H7LKwud1DUZCTSI=s100","interactionStatistic":{"@type":"InteractionCounter","interactionType":{"@type":"EndorseAction"},"userInteractionCount":800}},"commentCount":0,"discussionUrl":"https://daily.dev/posts/is-event-driven-architecture-overkill-for-most-apps--lfyebz9ps","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":0},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"architecture","timeRequired":"PT9M"} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"CodeOpinion","item":"https://daily.dev/sources/codeopinion"},{"@type":"ListItem","position":3,"name":"Is Event-Driven Architecture Overkill for Most Apps?"}]} {"@context":"https://schema.org","@type":"FAQPage","@id":"https://daily.dev/posts/is-event-driven-architecture-overkill-for-most-apps--lfyebz9ps#faq","mainEntity":[{"@type":"Question","name":"What is the difference between a command and an event in event-driven architecture?","acceptedAnswer":{"@type":"Answer","text":"A command invokes behavior, like DeliverShipment, and is an instruction typically handled by one consumer responsible for doing the work.
