Simplify your infrastructure and boost productivity with event-driven architectures and Momento

Build high-scale, flexible, and secure systems faster than ever—while lowering total cost of ownership.

Why Momento

Skip the infrastructure and stick with simple API calls to build powerful, managed systems that let you focus on what really matters.

Reduce Complexity

No APIs to build. No connections to manage. Just make simple API calls and go.

Connect Everywhere

Trigger any endpoint with access to the internet in response to a message. Or connect your systems together directly with a persistent connection to our event bus.

Scale Effortlessly

Develop software that adapts fanout or serial connections, smoothly scaling from single modules to large-scale systems, ensuring reliable and flexible communication flow.

Archive and Replay Events

Add your events to a Momento Cache list as they are published to build an archive. Automatically expire the events after a set time or replay them from a certain point in time.

Event-driven architectures and Momento

Build a multi-language chat app with Momento

See how easy it is to build this chat application with automatic moderation and multilingual translation by using Momento Topics with webhooks, AWS Lambda, and Amazon Translate.

Get Building

Work seamlessly with AWS Lambda & Step Functions

Momento Topics with webhooks trigger any HTTP endpoint, meaning you can invoke complex workflows via Step Functions or Lamba with a single message.

Integrate directly with EventBridge

With our one-click integration with EventBridge, all messages published to a topic are dropped onto an event bus of your choosing.

Persist & archive messages

With Topics triggering your Lambda functions, you can save messages directly to DynamoDB to preserve event order and enable CQRS workflows or save the conversation history from your chats long term.

Cache large event payloads

Instead of using slow storage, cache your large event payloads in Momento Cache.

Frequently asked questions

How do you know when to use event-driven architectures?

Event-driven architectures are used in distributed systems to decouple services and enable component-level scaling and iteration. Certain areas of any application experience more traffic than others, and a decoupled system allows for independent growth and isolation. This not only lowers blast radius in failure scenarios, but also allows for vertical scaling when necessary.
‍
Momento provides a set of powerful services that enable event-driven architectures by loosely coupling services with Topics, storing events in Cache, and triggering stateless compute with webhooks.

What are the benefits of event-driven architectures?

Event-driven architectures rely on asynchronous communication. This allows components to operate independently, reducing dependencies and bottlenecks in your workflows. Designing modern systems in this way is crucial for maintaining system responsiveness and efficiency—particularly with fluctuating or inconsistent workloads.
‍
In addition to increased responsiveness, EDA promotes inherent scalability and resilience. Independent scaling of different components ensures the system can adapt swiftly to varying amounts of traffic without affecting the system as a whole. By isolating components, the architecture limits blast radius, or scope of potential disaster, if a failure occurs, enhancing reliability and uptime.
