Lecture 11: Cloud Integrations

Question 1

1. Synchronous communications
2. Asynchronous/ Event based

Answer 1

What are the two different ways for applications to talk to one another?

Question 2

Synchronous communication is application talking directly to one another and asynchronous/ event based is application talking to queue to interact with another application (like a middleman)

• Asynchronous/ event based communication is decoupled

Answer 2

What is the difference between synchronous communication and asynchronous/event based communication?

Question 3

• Can use SQS: queue model
• Can SNS: pub/sub model
• Using Kinesis: real time data streaming model

Answer 3

Synchronous between application can be a problem for high spikes in traffic so what can you do to solve that problem?

Question 4

Decouple

Question 6

__________ is used in SQS

Answer 6

Answer 7

Answer 18

AWS X-Ray

Question 19

decouple your applications

Answer 19

When using SQS or SNS, you apply the “_____________” principle. This means that IT systems should be designed in a way that reduces interdependencies -a change or a failure in one component should not cascade to other components.

Question 20
