+An SBOM (a Software Bill of Materials) is a machine-readable inventory document (that will be generated with each release build) that captures all the software components and dependencies, info on those components, and hierarchical relationships.
+
+## Impact
+
+### Positive
+- **Automation in CI/CD:** The CycloneDX Gradle Plugin can seamlessly integrate SBOM generation into the CI/CD pipeline, ensuring the SBOM is always up to date with each release. 
+
+
+- **Industry Standard:** CycloneDX is widely accepted in the industry, ensuring compatibility with other tools and making compliance with security standards easier. 
+
+
+- **Vulnerability Scanning:** With the ability to integrate with tools like [Anchore/Grype](https://github.com/anchore/grype#recommended), one can easily add vulnerability scanning to the process. 
+
+
+- **Format Conversion:** supports integration with Anchore/Syft for SBOM format conversion, providing flexibility to meet different ecosystem requirements.
+
+
+
+### Negative
+
+- **Tooling Overhead:** Maintaining additional tooling for SBOM generation (CycloneDX and optional tools like Grype and Syft) could increase the overhead for the project and team, in terms of learning and managing multiple components. 
+
+
+- **Build Time Impact:** The generation of an SBOM might increase the build time, especially as the project grows in complexity.
+
+
+### Risks
+
+- **Compliance Dependence:** Relying on CycloneDX as the primary tool for SBOM generation means that any bugs, limitations, or updates to the plugin can impact your compliance process. 
+
+
+- **Tool Maintenance:** Keeping CycloneDX and its integration with vulnerability scanning tools like Grype up to date _could_ require ongoing maintenance efforts to ensure compatibility and security.
+
+
+- **Integration with Other Tools:** Future security or compliance needs _could_ require integration with other SBOM standards or tools not supported by CycloneDX, limiting flexibility.

 real-life load conditions, both normal and extreme.
- - Locust.io is free, open-source, scalable
- - Tests written in Python
- - Works with gRPC servers
- - Easy to use UI
- - Simple setup and task configuration
+
+## Impact
+
+### Positive
+
+- **Scalability:** Locust.io is highly scalable and can simulate millions of users, making it ideal for both small-scale and large-scale load tests. 
+
+
+- **Python-Based:** Writing tests in Python allows for flexibility and ease of use, especially for teams already familiar with the language. 
+
+
+- **Cost Efficiency:** Locust.io is open-source, and doesn’t require licensing fees, which can reduce the overall cost of performance testing.
+
+
+### Negative
+
+- **Limited Features:** Compared to more feature-rich tools, Locust.io might lack advanced performance monitoring or detailed reporting features. 
+
+
+- **Manual Script Writing:** Test scripts need to be manually written, which could be more time-consuming compared to GUI-based test creation offered by tools like JMeter or Artillery.io.
+
+
+### Risks
+
+- **Scalability Complexity:** While Locust.io is scalable, setting up distributed testing across multiple machines can introduce complexity, especially for teams with limited experience in handling distributed systems. 
+
+
+- **Tool Ecosystem:** If future testing needs expand beyond Locust.io's capabilities, there may be a need to switch or integrate with other tools, leading to additional complexity or costs. 
+
+
+- **Resource Usage:** Running large-scale tests using Locust.io may require significant system resources, which could impact cost and infrastructure planning.

 We will use [Docker](https://docs.docker.com/get-started/overview/) for containerization of our application.
 
+
 ## Status
 
 Accepted.
 
 ## Context
 
 Docker is an open platform for developing, shipping, and running applications. Docker provides the ability to package and run an application in a loosely isolated environment. Some benefits of using Docker:
-- Develop your application and its supporting components using containers.
-- The container becomes the unit for distributing and testing your application.
-- When you’re ready, deploy your application into your production environment, as a container or an orchestrated service.
-- Allows for responsive deployment and scaling.
 
-[Reference](https://docs.docker.com/get-started/overview/)
+
+## Impact
+
+### Positive
+
+- **Compatibility:** Docker containers can run consistently across various environments (development, testing, production), reducing compatibility issues and making it easier to move applications between different environments.
+
+
+- **Isolation:** Each container runs in its own isolated environment, which minimizes conflicts between applications and simplifies dependency management.
+
+
+- **Scalability:** Docker supports scaling applications easily through container orchestration tools like Kubernetes, allowing for better resource management and load handling.
+
+
+- **Rapid Development:** Containers can be quickly built, tested, and deployed, accelerating the development cycle and improving productivity.
+
+
+- **Ecosystem and Community:** Docker has a large and active community, providing a wealth of resources, tools, and best practices that can help in troubleshooting and optimization.
+
+
+### Negative
+
+- **Complexity in Orchestration:** managing a large number of containers can introduce complexity, especially without proper orchestration tools.
+
+
+- **Security Considerations:** Containers share the same OS kernel, which can pose security risks if not properly managed (e.g., vulnerability exposure).
+
+
+### Risks
+
+
+- **Vendor Lock-In:** Relying on specific Docker features or services might lead to challenges in migrating to other containerization solutions in the future.
+
+
+- **Configuration Drift:** As applications evolve, keeping container configurations consistent across different environments can be challenging, potentially leading to discrepancies.
+
+
+- **Data Persistence:** Managing data persistence for stateful applications can be complicated with Docker containers, requiring additional solutions like volumes or external databases.

 Terraform is multi-cloud and multi-tool, has a full-featured DSL, tracks state and dependencies, and is agentless.
 Terraform is also used by ReportStream.
 
+## Impact
+
+### Positive
+
+- **Multi-Cloud Support:** Terraform allows deployment across multiple cloud providers (e.g., AWS, Azure, GCP), providing flexibility and avoiding vendor lock-in. 
+
+
+- **State Management:** Terraform tracks the state of your infrastructure, which helps prevent configuration drift and makes it easier to manage changes over time.
+
+
+- **Declarative Language:** The HashiCorp Configuration Language (HCL) is easy to read and write, making it accessible for both developers and operations teams.
+
+
+- **Community, Ecosystem and Version Control:** Terraform has a large community, a wealth of modules, and an extensive ecosystem of plugins and integrations, making it easier to find solutions and share best practices. Storing Terraform configurations in Git allow teams to track changes and roll them back if needed.
+
+
+- **Automation and Integration:** Terraform can be integrated into CI/CD pipelines, allowing for automated infrastructure deployments alongside application code.
+
+
+### Negative
+
+
+- **State File Management:** Managing the state file can introduce complexities, especially in teams where multiple people may modify infrastructure, leading to potential conflicts or errors.
+
+
+- **Dependency Management:** Although Terraform manages dependencies between resources, complex infrastructures may require careful planning and a deep understanding of how dependencies interact, which can complicate deployment processes.
+
+
+### Risks
+
+- **State File Security:** The state file can contain sensitive information, so it's critical to implement proper security measures to protect it (e.g., using remote state storage with access controls).
+
+
+- **Inconsistencies Across Environments:** Without strict version control and practices in place, discrepancies can arise between different environments (development, staging, production).
+
+
+- **Vendor Lock-In:** While Terraform itself is multi-cloud, reliance on specific providers' features or modules can lead to some level of vendor lock-in over time.
+
+- **Tool Updates:** Regular updates to Terraform or its providers could introduce breaking changes or require modifications to existing infrastructure code, which might affect ongoing deployments.
