Virtual Bootstrap VPN Routing for Faster Cloud Region Buildout
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for building cloud data centers in new regions are time-consuming, error-prone, and inefficient due to manual operations and complex coordination, limiting a cloud service provider's ability to scale computing resources quickly.
Innovation Solution
A Cloud Infrastructure Orchestration Service (CIOS) is used to automate and optimize the bootstrapping process by utilizing a virtual bootstrap environment (ViBE) and a Multi-Flock Orchestrator (MFO) to manage resource provisioning and deployment, identifying dependencies, and enabling parallel processing to reduce manual intervention.

Engineering Contradiction Analysis
1Productivity
If manual operations are used to bootstrap services and build regions, then configuration control and service deployment are achieved, but substantial time costs and manual configuration errors occur
Solution Approach 1:
The patent creates a virtual bootstrap environment (ViBE) in advance within an existing region before the target region is ready. Services are pre-configured and tested in this virtual environment, allowing the bootstrapping process to proceed automatically once the target region is available, eliminating manual operations during the actual region build.
Solution Approach 2:
The ViBE acts as an intermediary between the existing region and the target region. It provides a intermediate environment where bootstrap services can be prepared and validated before being deployed to the target region, reducing direct manual intervention and configuration errors.
2Reliability
If manual configuration is used to bootstrap services, then service dependencies can be managed, but configuration errors and lack of scalability occur
Solution Approach 1:
The system implements automated service dependency resolution where the orchestration service automatically identifies, configures, and deploys services in the correct dependency order within the ViBE. The system self-manages the complex configuration tasks without requiring manual intervention, reducing both errors and operational complexity.
Solution Approach 2:
The patent implements automated feedback mechanisms where the orchestration service monitors service deployment status, validates configurations, and automatically adjusts the bootstrapping process based on service dependencies and regional availability, ensuring reliable deployment without manual configuration management.
3Extent of automation
If a virtual bootstrap environment is created in advance, then automated service deployment is enabled, but networking configuration complexity increases
Solution Approach 1:
The patent segments the networking configuration into distinct components: the ViBE network isolated within the existing region, and the target region network. Each has its own routing table and network addresses. The VPN router provides a controlled interface between these segments, simplifying the overall networking complexity by dividing it into manageable, isolated parts.
Solution Approach 2:
The VPN router serves as a networking intermediary between the ViBE and the target region. It handles route reflection and network address translation, automatically managing the complex routing requirements between the virtual bootstrap environment and the target region without requiring manual networking configuration.
4Ease of operation
If secondary network addresses are exposed for anycast routing, then service accessibility is improved, but routing table complexity increases
Solution Approach 1:
The patent implements anycast routing by exposing secondary network addresses that are copied from the primary service addresses. Multiple instances of the same service can be accessed through these copied addresses, improving service accessibility and load distribution while the underlying routing table remains managed by the VPN router through route reflection.
Solution Approach 2:
The VPN router acts as an intermediary that manages the routing tables for secondary anycast addresses. It performs route reflection to distribute these addresses appropriately without requiring complex manual routing configuration, automatically handling the mapping between anycast addresses and actual service instances.
Data Source
AI summary
Techniques are disclosed for establishing a distributed virtual private network within a virtual bootstrap environment. A distributed computing system can generate a virtual cloud network in a data center of a host region. The virtual cloud network can include a plurality of host instances, including an instance hosting a virtual private network router. A second instance can provide a secondary network address to the virtual private network router. A third instance can send a request addressed to the secondary network address. The virtual cloud network may route the request to the virtual private network router according to a default route of a routing table. The request may then be forwarded by the virtual private network router to the secondary address using a networking tunnel established between the first instance and the second instance.
