4.1 Characteristics of Cloud Computing Flashcards
What is cloud computing?
A flexible, cost-effective, and scalable solution for storing, managing, and processing data using remote servers.
What does ‘high availability’ mean in cloud computing?
It refers to systems designed with minimal downtime, such as achieving ‘five nines’ uptime (99.999%).
What are the two types of scalability in cloud computing?
Vertical Scaling (adding resources to a single server) and Horizontal Scaling (adding more servers to share the workload).
What is rapid elasticity in cloud computing?
The ability to automatically scale resources up or down based on demand, ensuring cost efficiency.
What does ‘metered utilization’ mean in cloud services?
Businesses pay only for the resources they consume, often based on usage per second, minute, or other metrics.
What are shared resources in cloud computing?
Physical hardware shared among multiple users via virtualization, reducing costs and optimizing usage.
What is the purpose of file synchronization in cloud computing?
To ensure files are accessible and up-to-date across devices and locations for seamless collaboration.
What is an example of rapid elasticity in action?
Automatically provisioning additional resources during a viral campaign.
How does cloud computing reduce costs?
By offering pay-per-use models and avoiding large upfront investments in IT infrastructure.
What is the advantage of high availability in cloud systems?
Ensures business continuity with minimal downtime and fault tolerance.
How does cloud computing enable global collaboration?
By providing synchronized files and systems that teams can access worldwide without latency issues.
What are the primary benefits of cloud computing?
Cost savings, scalability, efficiency, business continuity, and global collaboration.
How does horizontal scaling improve system performance?
By adding more servers to share the workload, ensuring better performance during high demand.
What is the role of measured service in cloud computing?
To monitor and limit resource usage, ensuring customers stay within quotas or pay for overages.
