ABC
What is edge computing reduces latency by processing data closer to the source, but alternatives like dedicated low-latency zones in cloud regions or hybrid cloud architectures can also be used?
Critique the use of edge computing in latency-sensitive cloud applications and propose an alternative solution.
What are services like AWS Kinesis for ingestion, AWS Lambda for processing, and Amazon DynamoDB for fast storage?
Design a solution to enable real-time fraud detection for credit card transactions using a cloud provider’s services.
What is event-driven architecture?
This architectural pattern uses components that communicate via events and is essential in real-time, scalable systems.
What is eventual consistency?
This is the name of the consistency model used in distributed cloud systems where reads may return stale data, but availability is maintained.
What is managing service-to-service communication, including traffic control, security, and observability?
A service mesh like Istio is used for this purpose in microservice-based cloud applications.
What is the Horizontal Pod Autoscaler?
This Kubernetes object automatically adjusts the number of pods in a deployment based on CPU usage.
What is vertical scaling increases resources on a single node, while horizontal scaling adds more nodes to the system?
Compare vertical scaling and horizontal scaling in cloud systems.
What is Google Cloud Dataflow?
Name the Google-managed service used for real-time stream analytics that competes with Amazon Kinesis.
What is virtualization?
The technique of running multiple virtual machines on a single physical machine is called this.
What is Infrastructure as a Service (IaaS)?
This cloud model provides users with hardware resources over the internet, such as virtual machines and storage.
