1.2 Fundamental Cloud Concepts Flashcards
(20 cards)
Define:
latency
in the context of cloud computing
The time it takes for data to travel from one point to another in a network.
Lower latency means faster response times and better application performance.
True or False:
High latency is desirable in cloud applications.
False
High latency leads to slower performance and degraded user experiences.
Why is Total Cost of Ownership (TCO) important?
It measures all costs associated with infrastructure over time, including acquisition, support, downtime, and training.e, and training.
TCO provides a more comprehensive view of long-term cloud investment compared to just initial purchase price.
Compare CapEx vs OpEx in cloud computing.
- CapEx: upfront infrastructure investment;
- OpEx: recurring operational expenses.
Cloud adoption shifts expenses from CapEx to OpEx, providing more financial flexibility.
What is the primary benefit of the OpEx model in cloud computing?
It allows organizations to pay for only what they use, reducing upfront costs and enabling scalability.
OpEx enables financial agility and is more aligned with dynamic workloads.
Fill in the blank:
A ________ is a specific geographic area where Google Cloud resources are hosted.
zone
Zones are grouped into regions and are the fundamental deployment locations in Google Cloud.
Explain the difference between a Google Cloud region and a zone.
A region is a geographic location that contains multiple isolated zones.
Deploying across multiple zones in a region increases redundancy and fault tolerance.
Why is Google Cloud’s global network architecture important for performance?
- Minimizes latency
- Increases reliability
- Ensures fast access to services across the globe
Google’s private fiber network helps reduce the number of network hops, improving speed and consistency.
What helps improve reliability in cloud infrastructure?
Deploying to multiple regions.
Multi-region deployments ensure high availability even during outages in a single region.
True or False:
Google Cloud automatically manages traffic routing to optimize performance across its network.
True
Google Cloud uses edge caching, load balancing, and intelligent routing to enhance performance.
Define:
network bandwidth
The amount of data that can be transferred over a network in a given time.
Higher bandwidth supports more concurrent users and faster application performance.
Scenario:
A company wants to deploy its app to reduce latency for users in Europe and Asia. What should they consider?
Deploy to regions in both Europe and Asia to serve users closer to the source.
Geographic proximity improves speed and reliability by reducing data travel distance.
List two key benefits of cloud computing related to performance and cost.
- Scalability on demand
- Lower total cost of ownership (TCO)
Cloud allows dynamic scaling and pay-as-you-go pricing, reducing unnecessary spend.
Describe how cloud computing enables elasticity.
Resources can automatically scale up or down based on demand.
Elasticity means resources can automatically scale up or down based on demand.
Explain how Google Cloud’s network architecture supports global reliability.
It uses globally distributed data centers, edge caching, and redundant connections to ensure uptime and low latency.
Redundant infrastructure allows failover to minimize disruptions.
True or False:
An organization must manually configure fault tolerance across Google Cloud zones.
False
Google Cloud offers built-in services and deployment configurations that support high availability across zones.
How does Google’s undersea fiber network contribute to performance?
- Reduces latency
- Increases data transfer speed
This infrastructure connects Google’s global data centers efficiently, and helps to improve service across continents.
Scenario:
Scenario: A startup has unpredictable traffic patterns. What cloud pricing model would be most beneficial?
OpEx
Pay-as-you-go model
This model lets them scale resources based on demand without upfront investment.
What is a key advantage of distributing workloads across multiple zones within a single region?
It improves service availability and fault tolerance without cross-region latency.
This setup offers resilience while maintaining local performance.
What is the relationship between performance, latency, and user experience in cloud applications?
Lower latency improves performance, which directly enhances the end-user experience.
Optimizing for low latency ensures applications respond quickly, which is critical for user satisfaction and retention in cloud-based services.
