Cloud Network Isolation Architecture for Remote aPaaS Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Large enterprises face challenges in integrating and streamlining their operations due to the proliferation of siloed custom software applications, which hinder their ability to innovate, meet regulatory requirements, and efficiently manage data and systems.
Innovation Solution
A remotely-hosted Application Platform as a Service (aPaaS) system that automates workflows, supports standardized application components, and provides secure, scalable infrastructure for developing and managing applications, including a multi-instance architecture to isolate customer data and enhance security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If a remotely-hosted aPaaS system is deployed on public cloud network infrastructure, then the operator does not have to devote time to provision or deploy its own infrastructure to host services, but the operator may not have full control over the infrastructure configuration and security policies
Solution Approach 1:
The system segments infrastructure management into two distinct layers: the public cloud network provides standardized virtual machine infrastructure, while the aPaaS system implements custom security policies, access controls, and configuration management software. This segmentation allows operators to leverage cloud convenience while maintaining control through software-based configuration management.
2Reliability
If computational instances are isolated from one another in the public cloud network, then customer data security is enhanced, but network connectivity and integration between instances become more complex
Solution Approach 1:
The aPaaS system introduces intermediary components including virtual private networks (VPNs), network gateways, and API gateways that mediate communication between isolated computational instances. These intermediaries enable secure data exchange and integration while preserving the isolation boundaries that ensure security.
3Reliability
If a quarantine system is implemented for approval of updates to configuration, software, or database schema, then system stability and security are improved, but deployment time and process complexity increase
Solution Approach 1:
The quarantine system implements preliminary action by creating isolated test environments where configuration updates, software changes, and database schema modifications are validated before being deployed to production. This preliminary testing phase catches errors early and prevents unstable configurations from reaching live systems.
4Adaptability or versatility
If infrastructure services are positioned in the provider network rather than the public cloud network, then operational control and security policy enforcement are improved, but infrastructure cost and complexity increase
Solution Approach 1:
The aPaaS system implements universal, multi-functional infrastructure services that can operate in both public cloud and provider network environments. Configuration management, security policy enforcement, and application deployment capabilities are designed to be environment-agnostic, allowing the same software stack to function across different infrastructure locations.
Data Source
AI summary
A software architecture within a public cloud network may include units of: (i) a plurality of computational instances respectively related to managed networks, (ii) a plurality of servers configurable as load simulators, (iii) administrative components configured to deploy and update the software architecture, and (iv) shared infrastructure services, wherein the units of the software architecture are implemented on virtual machines of the public cloud network and are connected to but logically isolated from one another by way of different access controls or policies. A provider network, coupled to the software architecture by way of network gateways within the shared infrastructure services, may be configured to deliver the configuration, software packages, and database schema to the infrastructure-as-code platform.
