Cloud Infrastructure Orchestration Rollback for Configuration Recovery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cloud infrastructure orchestration services face challenges in efficiently managing infrastructure provisioning and deployment, particularly in large-scale environments, with manual interventions leading to deviations and a lack of automated tools that can handle both provisioning and deployment seamlessly, and existing tools lack the ability to automatically handle rollback operations due to the absence of tracking previous configurations.
Innovation Solution
A cloud infrastructure orchestration service (CIOS) that automates both provisioning and deployment using a declarative approach, maintaining a history of configurations and variable inputs to enable automatic rollback to a previous state in case of failures, thereby reducing manual errors and ensuring robustness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If automated rollback operations are implemented, then system reliability is improved, but device complexity increases due to the need for configuration history tracking
Solution Approach 1:
The system performs preliminary actions by capturing and storing configuration states before infrastructure changes are applied. This allows the rollback mechanism to restore to known good states without requiring complex real-time analysis during failure scenarios.
Solution Approach 2:
The system creates copies of configuration states at different points in time, storing them in a history database. These copies enable the rollback operation to restore previous configurations without needing to maintain the original state, simplifying the rollback mechanism.
2Ease of operation
If manual intervention is used for infrastructure provisioning, then ease of operation is reduced, but automation extent is limited
Solution Approach 1:
The system enables self-service by automatically capturing configuration states, detecting failures, and executing rollback operations without requiring manual intervention. The infrastructure orchestration service autonomously manages the entire lifecycle including provisioning, monitoring, and recovery.
Solution Approach 2:
The system implements feedback mechanisms by continuously monitoring infrastructure health and comparing actual states against desired states. When deviations are detected, the system automatically triggers rollback operations to restore compliance, creating a closed-loop control system.
3Loss of information
If configuration history is tracked for rollback, then loss of information is reduced, but device complexity increases
Solution Approach 1:
The system performs preliminary capture of configuration states before changes are applied, storing them in a structured format in a database. This preliminary action ensures that configuration information is preserved in an organized manner that simplifies later retrieval and restoration operations.

AI summary
Techniques for implementing rollback of infrastructure changes in an infrastructure orchestration service are described. In certain examples, an infrastructure orchestration service is disclosed that manages both provisioning and deploying of infrastructure assets within a cloud environment. The service receives a plan comprising a set of instructions associated with a set of infrastructure assets of an execution target and identifies a first state of the set of infrastructure assets. The service executes the set of instructions in the plan to achieve a second state for the set of infrastructure assets. Based in part on the executing, the service receives a trigger for rolling back the plan to restore the set of infrastructure assets in the plan to the first state and executes a rollback plan for the plan. The service then transmits a result associated with the execution of the rollback plan.
