The document discusses the transformation of application architecture through microservices and serverless strategies to enhance agility and scalability in modern digital businesses. It outlines key technologies and concepts for implementing these architectures, such as event-driven systems, messaging services, and automation tools within AWS. Additionally, it emphasizes the importance of decoupling services and utilizing specialized data management strategies to support innovation and operational efficiency.

4. A serverless business strategy
Serverless-First is the decision to opt for serverless technologies
in your application as a first choice.
 No server management
 Flexible, automated scaling
 Pay for value
 Automated high availability
What do we mean when we say serverless?

22. event
[i-’vent] noun
A signal that a system’s
state has changed.

23. What are events?
• Event becomes the primary mechanism for sharing information across
services about the change in state
• Immutable - cannot change the past
• Events have semantic intent, represented as verbs in the past tense,
e.g. “customer_created”
• Lightweight, correlated by properties that are common across bounded
contexts “customer_id”

24. Events are observable, not directed
Directed commands Observable events

25. Challenges with distributed systems (Synchronous API)
Producer
Consumers

26. De-couple services with event routers
Abstracts producers and
consumers
Selects and filters events

27. Improve responsiveness and reduce dependencies

28. Improve resiliency and scalability with event stores
Event store

29. Event stores apply to messages and streams
Message Processing Stream Processing
• The individual message is the unit of work
• Computation/processing per message
• Message occurrence can varies
• Message are deleted after consumption
• No need to track the position
• DLQ functionality built-in
• The message stream is the unit of work
• Complex computation on many messages
• Constant stream of messages
• Messages are available after consumption until
expiration
• Each client needs to track the current position in
the stream
• No built-in DLQ functionality

30. Reliable, resilient, and independently scalable
“If your application is cloud-native, or large-scale, or distributed, and doesn’t include a
messaging or event component, that’s probably a bug.” Tim Bray

Amazon
Simple Queue Service
Fully managed message queues for microservices, distributed
systems, and serverless applications

36. Amazon Simple Queue Service (SQS)
WHAT IT IS
Simple, flexible, fully
managed message
queuing service for
reliably and
continuously
exchanging any volume
of messages from
anywhere
(Standard and FIFO)
USE CASE
Build decoupled, highly
scalable microservices,
distributed systems,
and serverless
applications in the
cloud
COOL CAPABILITIES
Nearly infinite scalability
without pre-
provisioning capacity
25B messages per hour
Event Source

37. Processing High Volume Big Data With SQS

38. Better Together: SQS as an Event Source
Before:
- Customer wrote a service to poll an SQS queue including
logic to back off polling, delete message, etc.
- Customer monitored, scaled, and maintained
After:
- Lambda service is managing message polling, scaling of
consumers, receiving messages, passing on to Lambda
function, and deleting messages.
Result:
- Customers write and manage less code
- Customers leverage SQS and Lambda together to automate
functions.
Facts:
- SQS is the #1 event source for Lambda
New SQS FIFO as Lambda event-trigger launched Nov 2019!

• Reacting to events from SaaS
applications, AWS services (115), or
customer applications.
• Pre-defined schema: Create rules
that are applied across the entire
event body to filter before pushing to

• High throughput and low latency
events published by other
applications, microservices, or AWS
services.
• Very high fanout (thousands or
millions of endpoints)
