Cloud Computing fundamentals

Question 1

A System has to meet 5 different characteristics to define that as “Cloud” (AWS/AZURE/GCP). What are they

Answer 1

1. On-Demand Self-Service
2. Broad Network Access
3. Resource Pooling
4. Rapid Elasticity
5. Measured Service

Question 2

On-Demand Self-Service

Answer 2

Can Provision capabilities as needed without human interaction
Provision and terminate using a UI/CLI without human interaction.

Question 3

Broad Network Access

Answer 3

Capabilities are available over the network and accessed through standard mechanisms
Access services over any networks on any devices using standard protocols and methods.

Question 4

Resource Pooling

Answer 4

1. There is sense of location indepedence no control or knowledge over the exact location of the resources
2. Resources are pooled to serve multiple consumers using multi-tenan model
   Economies of scale, cheaper service

Question 5

Rapid Elasticity

Answer 5

1. Capabilities can be elastically provisioned and released to scale rapidly outward and inward with demand
2. For the consumers, the capabilities available for provisioning often appear to be unlimited
   Scale up(OUT) and down(IN) automatically in response to system load.

Question 6

Measured Service

Answer 6
