Cloud Subscription Pooling for Automated VM Deployment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current VM deployment in public cloud systems requires significant manual effort and access to multiple subscriptions, making it cumbersome for enterprises with many users and subscriptions to efficiently manage resources.
Innovation Solution
A method of managing public cloud resources by grouping subscriptions into reservations with constraints, allocating these reservations among principals, and generating a deployment plan based on workload metadata to automatically select the appropriate subscription for provisioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual subscription selection is used for VM deployment, then users can access specific subscriptions, but significant manual effort is required and deployment efficiency decreases
Solution Approach 1:
The system pre-groups multiple subscriptions into reservations before deployment is needed. Administrators configure reservations in advance that define constraints and allocate subscriptions to principals, so when a user requests VM deployment, the system can immediately select from pre-configured options without manual intervention.
Solution Approach 2:
Reservations act as an intermediary layer between users and subscriptions. Instead of users directly selecting from multiple subscriptions, they request deployment through the reservation system, which automatically matches workload constraints with appropriate reservations and selects suitable subscriptions, eliminating manual subscription selection.
2Adaptability or versatility
If users need access to multiple subscriptions for deployment, then resource flexibility is improved, but system complexity and access management difficulty increase
Solution Approach 1:
The system segments the complex subscription management task into distinct components: reservations (which group subscriptions), principals (which receive allocations), and workload constraints (which guide selection). This segmentation allows users to interact with simplified reservation objects rather than managing individual subscriptions directly.
Solution Approach 2:
Reservations serve multiple functions simultaneously: they group subscriptions, allocate resources to principals, enforce constraints, and enable automated selection. This multi-functionality reduces the need for separate mechanisms for each management task, simplifying the overall system despite supporting multiple subscriptions.
3Productivity
If automated deployment planning is implemented, then manual effort is reduced, but system complexity in managing reservations and constraints increases
Solution Approach 1:
The deployment planning system operates autonomously by automatically matching workload constraints with reservation constraints, selecting appropriate subscriptions, and generating deployment plans without human intervention. The system serves itself by making intelligent decisions based on pre-configured reservation rules and current resource availability.
Solution Approach 2:
The system manages complexity by working with configurable parameters and constraints that can be adjusted without changing the underlying system architecture. Reservation constraints, workload metadata, and allocation rules are all parameterized, allowing flexible management through configuration rather than structural modification.

AI summary
An example method of managing virtualized computing resources provided by a public cloud includes: grouping subscriptions in the public cloud into reservations, each of the reservations including constraints on virtualized computing resources provided by at least one of the subscriptions; allocating the reservations among a plurality of principals; receiving a request to provision a workload from a user associated with a first principal of the plurality of principals, wherein the workload includes metadata describing constraints of the workload; generating a deployment plan for the workload based on the metadata therein and at least one of the reservations allocated to the first principal, the deployment plan specifying a first subscription of the subscriptions; and transmitting a deployment.
