Advances, Systems and Applications
Table 1 Examples where cloud user concerns are about “What” while the cloud provider needs to decide “how”
Cloud type | Scenario | Cloud user | Cloud provider | Cloud user’s concerns (intents) | Cloud provider’s concerns (resource decisions) |
|---|---|---|---|---|---|
Public cloud | MLaaS | Common MLaaS users | MLaaS provider | Time taken to accomplish a given training task, etc. | Amount of computation resources to be allocated in order to meet the training time restrictions from the user |
NFV implemented on Private cloud | vEPC | Network traffic management department in a CSP | Virtualization platform management department in a CSP | - High reliability of the communication service - Packet processing capacity and latency | - SFC composition (e.g. add standby SFC) to realize the high reliability requirement - Amount of computation resources to be allocated in order to meet the packet processing capacity and latency requirement |
Public cloud | Ecommerce service on cloud | E-commerce company | Public cloud provider | - High reliability, security levels of the communication service - Packet processing capacity and latency | - SFC composition (e.g. add standby SFC, add packet filtering instance to SFC) to realize the high reliability and security requirements - Amount of computation resources to be allocated in order to meet the packet processing capacity and latency requirement |
