Cloud Concepts - Key Cloud Concepts Flashcards
What is the concept of on-demand resourcing in cloud computing?
On-demand resourcing means that resources within the cloud are immediately available for allocation whenever and wherever they are needed, eliminating the need for ordering, installing, and configuring hardware.
What is scalability in cloud computing?
Scalability in cloud computing refers to the ability to rapidly adjust the resources of an environment up or down, both in terms of power and performance (scaling up and down) and the number of instances used (scaling in and out).
What is the advantage of scalability in the cloud compared to on-premise solutions?
Scalability in the cloud offers cost advantages compared to on-premise solutions, as resources can be easily adjusted based on demand, avoiding the need for overprovisioning or underutilization.
What is the concept of economy of scale in cloud computing?
Economy of scale in cloud computing refers to the cost benefits achieved due to the large scale of shared resources provided by public cloud offerings, optimized through virtualization technology. This results in lower resource costs compared to traditional hosting.
What is the flexibility and elasticity offered by cloud computing?
Cloud computing provides great flexibility and elasticity in designing environments. Users can customize their environment by choosing the required amount and duration of resources, using only what is necessary.
How does cloud computing support growth for organizations?
Cloud computing enables organizations to grow by providing a wide range of resources and services. The on-demand nature of the cloud reduces growth constraints compared to traditional on-premise environments. Additionally, cloud vendors’ global networks facilitate reaching global customers easily.
What is utility-based metering in cloud services?
Utility-based metering means that users pay for cloud services based on their actual usage. Similar to paying for electricity only when it is consumed, users are billed only for the resources they use, allowing for cost optimization.
What is the concept of shared infrastructure in cloud computing?
Shared infrastructure refers to the virtualization of hosts in the cloud, allowing multiple tenants to run instances on the same physical hardware. This reduces the need for excessive physical hardware, resulting in cost savings for customers.
How does cloud computing ensure high availability of data and services?
Cloud computing providers replicate core services and data across different geographic zones and regions, automatically ensuring data durability and service availability without the need for additional configuration.
How is security addressed in cloud computing?
Public cloud vendors like AWS and Microsoft Azure adhere to global compliance programs and operate under the shared responsibility model. Vendors provide a high standard of security for the underlying infrastructure, while users are responsible for architecting security within the cloud using available tools and services.
