In the context of microservices, what is the purpose of an API?
Define how services interact with each other
Why is service discovery essential in microservices architectures?
To enable services to discover and connect to each other automatically
What is the main goal of load balancing in microservices architectures?
Distribute incoming requests among multiple service instances
Which component within a distributed system is responsible for locating and communicating with other components?
Service Discovery
What role do software agents serving alongside services play in a service mesh?
Mediate inbound and outbound traffic for the service
What is the benefit of decoupling producers and consumers in event-driven applications?
Increases system flexibility
Which event streaming platform is designed for low latency and high throughput?
Amazon Kinesis
What is the main concept behind event sourcing?
Storing all changes to data as a sequence of events
Which architectural patterns are often used together in event-driven architectures?
Event Sourcing and CQRS
What are important factors to consider when choosing an event streaming platform?
Scalability, features, ease of use, and cloud integration
Which event-driven platform is known for being a leader in the field and highly scalable?
Apache Pulsar
What is the core idea of Event-Driven Architecture (EDA)?
EDA focuses on events as the central mechanism for communication
In EDA, what is the role of event consumers?
Listen for events and take corresponding actions
How does TLS encryption contribute to microservices architectures?
Ensure that data exchanged between services remains confidential and secure
What distinguishes event producers in an Event-Driven Architecture (EDA)?
They generate events whenever something significant happens
What advantage does Event-Driven Architecture (EDA) offer in terms of service coupling?
Enhances loose coupling where services don't need to know each other's implementation details
How does Transport Layer Security (TLS) contribute to securing communication over a computer network?
Encrypts information to ensure only authorized parties can access it
What does the analogy of a city intersection represent in the context of event streaming platforms?
Platform managing the flow of events efficiently
Which aspect of event streaming platforms enables faster decision-making and improved user experiences?
Supporting real-time processing
What role do consumers play in the analogy of a city intersection when comparing to event streaming platforms?
Reacting to specific events
How do event streaming platforms ensure events are delivered reliably?
By handling massive data volumes efficiently
Which feature makes event streaming platforms ideal for applications with increasing event traffic?
Scalability for growing data volumes
In the context of event streaming platforms, what does real-time processing enable applications to do?
React to events immediately
Why is having an audit trail beneficial?
Makes it easier to track how data evolved over time
What is the primary benefit of CQRS (Command Query Responsibility Segregation) concept?
Separating concerns of reading data from updating data
How does event sourcing contribute to CQRS implementation?
It acts as the single source of truth for the system
In what way can CQRS enhance maintainability?
By separating concerns, making the code easier to understand and modify
What does having separate databases for processing orders and product searches lead to?
Improved performance due to optimized data models
How does event sourcing provide benefits when used in conjunction with CQRS?
It serves as a natural source of events for CQRS implementations
