Cloud Service Instance Pool Management for Provisioning Latency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing cloud computing systems face delays and inefficiencies in provisioning services due to time-consuming instance creation processes, especially under high demand, and imprecise capacity management, leading to inadequate resource allocation and delays in service availability.
Innovation Solution
Implementing a system that proactively constructs and maintains pools of pre-provisioned and pre-orchestrated instances, allowing for quick provisioning of executing instances by executing pre-configured computing environments and software, and using feedback loops for dynamic capacity management across zones.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If on-demand instance creation is used for cloud services, then service flexibility and accessibility are improved, but provisioning time increases significantly
Solution Approach 1:
The system pre-provisions and pre-orchestrates service instances before they are actually needed. When a service request arrives, the instance is already prepared and can be activated immediately, eliminating the lengthy provisioning process that would otherwise be required during the request fulfillment phase.
2Ease of manufacture
If traditional instance provisioning is used, then resource allocation is simplified, but service availability is delayed under high demand
Solution Approach 1:
Instances are pre-provisioned and pre-orchestrated in advance, so when demand occurs, the infrastructure is already in place and ready for immediate activation, ensuring service availability without delays.
Solution Approach 2:
The system continuously monitors service demand patterns and uses this feedback to dynamically adjust the pool of pre-provisioned instances, ensuring adequate resource allocation matches actual demand while maintaining simple automated management.
3Productivity
If pre-provisioned instances are maintained in pools, then provisioning speed increases, but system complexity increases
Solution Approach 1:
The system automatically manages the pools of pre-provisioned instances through self-service mechanisms, including self-provisioning, self-monitoring, and self-adjustment based on demand patterns, eliminating the need for manual intervention and reducing operational complexity despite the increased structural complexity.
4Measurement precision
If capacity management is performed manually, then control precision is maintained, but response time to demand changes increases
Solution Approach 1:
The system implements automated feedback loops that continuously monitor service demand, resource utilization, and instance performance, dynamically adjusting capacity allocation in real-time to match actual demand patterns with precise speed and accuracy.

AI summary
Systems, methods, and other embodiments associated with managing instances of services are described. In one embodiment, a method includes constructing pre-provisioned instances of a service within a first pool and constructing pre-orchestrated instances of the service within a second pool. In response to receiving a request for the service, the method executes executable code of a first pre-orchestrated instance as an executing instance and removing the pre-orchestrated instance from the second pool. A pre-provisioned instance is selected from the first pool to create a second pre-orchestrated instance within the second pool, and the pre-provisioned instance is removed from the first pool.
