Node Agent Tracking Facts for Multi-Tenant Cloud Resource Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Platform-as-a-Service (PaaS) offerings face inefficiencies and high costs due to the need for separate virtual machines for each application, leading to underutilization of resources and increased complexity in managing web applications in cloud environments, particularly in multi-tenancy scenarios where multiple applications coexist on the same node.
Innovation Solution
Implementing a server orchestration system with agents that track custom facts about nodes, such as the number of software repositories and resource pools, to optimize resource allocation, idle application management, and capacity calculation, enabling efficient hosting of multiple applications on a single node while maintaining security and segregation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate virtual machine is allocated to each application, then application isolation and security are improved, but resource utilization deteriorates and costs increase
Solution Approach 1:
The patent merges multiple applications onto a single virtual machine by implementing a containerization architecture where each application runs in an isolated container process. This allows multiple applications to share the same VM resources while maintaining logical isolation through container boundaries, thereby improving resource utilization without compromising application isolation.
Solution Approach 2:
The patent segments the VM into multiple isolated container environments, each hosting a separate application. This segmentation is achieved through process isolation mechanisms where each container appears as a separate process to its application, providing the necessary isolation and security while allowing resource sharing at the VM level.
2Productivity
If multiple applications are deployed on a single virtual machine, then resource utilization is improved, but security concerns and resource sharing complexity increase
Solution Approach 1:
The patent introduces a container runtime environment as an intermediary layer between the VM and multiple applications. This intermediary manages resource allocation, process isolation, and security boundaries, simplifying the complexity of resource sharing by providing a standardized interface and management mechanism for deploying and isolating multiple applications on a single VM.
3Reliability
If a virtual machine is initialized for each application deployment, then application isolation is ensured, but initialization costs and resource waste increase
Solution Approach 1:
The patent combines multiple application deployments onto a single virtual machine to avoid repeated initialization costs. By hosting multiple isolated container processes within one VM, the system eliminates the need to initialize a new VM for each application, thereby reducing energy consumption and initialization overhead while maintaining application isolation through container boundaries.
4Productivity
If VM size is increased to accommodate larger applications, then application performance is improved, but resource waste increases for smaller applications
Solution Approach 1:
The patent applies local quality by allowing different container processes within the same VM to allocate resources according to their specific needs. Each container can be configured with appropriate resource limits and allocations based on the requirements of the hosted application, enabling small applications to use minimal resources while large applications can access sufficient resources, thereby optimizing overall resource utilization without waste.

AI summary
A mechanism for tracking applications on a node of a multi-tenant PaaS environment is disclosed. A method of the invention includes providing an agent of a server orchestration system on a multi-tenant node of a network-based application hosting system, wherein the node comprises a virtual machine (VM) of a cloud computing environment configured to host a plurality of Web application components of different owners, and maintaining, by the agent, a plurality of facts about the node. One of the facts is a number of source code management (SCM) software repositories on the node; each software repository containing at least one of the plurality of Web application components, which is determined by and updated by the agent to reflect the number of determined software repositories.
