Cloud Service Images for Consistent Cross-Environment Deployment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Deploying cloud services across different environments is complex due to the need for maintaining consistency and integrity of configurations and states, particularly in dynamic cloud environments where IP addresses and MAC addresses change, and managing interdependencies of compute instances, network configurations, and databases.
Innovation Solution
The use of service images that encapsulate configuration and runtime state, allowing for serialization and deserialization to create a consistent and reliable deployment process. This involves capturing all relevant data and configurations into a structured format, such as JSON, and using declarative provisioning and deployment systems to automate the setup of cloud resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If cloud services are deployed across different environments with dynamic IP addresses and MAC addresses, then adaptability is improved, but configuration consistency and reliability deteriorate
Solution Approach 1:
The patent creates a service image that is a copy of the entire service state including compute instances, network configurations, and database states. This copy captures all configuration data in a serialized format that can be transported to different cloud environments. The service image includes parameterized representations of IP addresses and MAC addresses that can be automatically adapted to the target environment while maintaining the structural consistency of the original configuration.
Solution Approach 2:
The service image is created in advance before deployment to a new environment. This preliminary action captures the complete service state including all interdependencies between compute instances, network configurations, and databases. By preparing the service image beforehand with all necessary configuration data, the patent eliminates the need to manually reconfigure services in the target environment, ensuring consistency while enabling adaptability.
2Manufacturing precision
If service deployment processes are manually executed to ensure configuration accuracy, then manufacturing precision is improved, but productivity deteriorates
Solution Approach 1:
The patent replaces manual mechanical deployment processes with automated computational processes. The service image is automatically serialized from the source environment and deserialized in the target environment, eliminating manual configuration steps. This automation maintains configuration accuracy through structured data formats and validation mechanisms while dramatically increasing deployment speed by removing human intervention bottlenecks.
Solution Approach 2:
The patent transforms service configurations into parameterized data structures within the service image. Configuration parameters such as IP addresses, MAC addresses, and resource identifiers are represented as replaceable variables that are automatically substituted during deployment. This parameterization approach ensures configuration accuracy through consistent data structures while enabling rapid automated deployment without manual intervention.
3Reliability
If complete service states including interdependencies are captured, then reliability is improved, but device complexity increases
Solution Approach 1:
The patent segments the complete service state into distinct components within the service image, including compute instances, network configurations, and database states. Each component is serialized independently with its own data structure, making the complex service state manageable and processable. This segmentation maintains reliability by capturing all interdependencies while organizing the complexity into structured, manageable units that can be independently validated and deployed.
Data Source
AI summary
Techniques discussed herein relate to generating and utilizing snapshots (also referred to as “service images”) of a cloud-based service. A snapshot may be generated within a source environment (e.g., one compartment and/or region) and re-instantiated in a target environment (e.g., a different compartment and/or region, the same compartment/region as would be the case in a recovery scenario). The snapshot may include serialized data of any suitable combination of resource metadata, images, block/boot volume content, runtime state data, environmental variables, and the like of the service of the source environment, at a time at which the snapshot was generated. The snapshot may be deserialized in the target environment and used to perform infrastructure and/or artifact/software releases to bring the control plane and/or data plane resources of the target environment to a desired state corresponding to the state of the service in the source environment when the snapshot was generated.
