This could be useful in use cases such as: - - - **Multi-tenant Applications**: If you're building a SaaS application that needs to provision Neptune instances on-demand, the `NeptuneAsyncClient` can help you automate this process programmatically. - - **Ephemeral Environments**: When you need to spin up and tear down Neptune resources as part of your CI/CD pipeline or within a Lambda environments, the `NeptuneAsyncClient` can streamline this process. - - **Scaling and Elasticity**: If your application needs to scale Neptune resources up or down based on demand, the `NeptuneAsyncClient` can help you manage these changes dynamically. - -2. **Integrations and Workflow Automation**: The `NeptuneAsyncClient` can be beneficial when you need to integrate Neptune provisioning and management into larger, automated workflows. For example: - - - **DevOps Tooling**: You can use the `NeptuneAsyncClient` as part of your infrastructure-as-code (IaC) tooling, such as building custom scripts that can provision Neptune resources on-demand. - - **Serverless Architectures**: When deploying serverless applications that rely on Neptune, the `NeptuneAsyncClient` can help you manage the Neptune components of your serverless stack. - - -3. **Rapid Prototyping and Experimentation**: The programmatic nature of the `NeptuneAsyncClient` can be beneficial when you need to quickly set up and tear down Neptune resources for prototyping, testing, or experimentation purposes. This can be particularly useful for: - - - **Proof-of-Concepts**: When validating ideas or testing new features that require a Neptune database, the `NeptuneAsyncClient` can help you provision the necessary resources with minimal overhead. - - **Performance Testing**: If you need to stress-test your Neptune-powered application, the NeptuneAsyncClient can help you programmatically create and manage the required test environments. - - **Data Migrations**: When migrating data between Neptune instances or across AWS Regions, the NeptuneAsyncClient can streamline the process of provisioning the necessary resources. - -The key advantage of the `NeptuneAsyncClient` is its ability to provide fine-grained, programmatic control over Neptune resources. This can be particularly valuable in dynamic, automated, or rapidly changing environments where the flexibility and programmability of the `NeptuneAsyncClient` can help streamline your application's Neptune-related infrastructure management. - -### Use Case Recommendation - -- Infrastructure as code (IaC): Prefer CDK, CloudFormation, or Terraform -- Dynamic provisioning in app - Use NeptuneAsyncClient -- Internal tooling or automation - Use NeptuneAsyncClient - - Manual ad hoc cluster setup - Use CLI or SDK (sync/async) - ## Resources This Basics scenario does not require any additional AWS resources. @@ -80,7 +49,7 @@ The Amazon Neptune Basics scenario executes the following operations. 8. **Delete the Neptune Assets**: - Description: Delete the various resources. - - Exception Handling: Check to see if an `ResourceNotFoundException` is thrown.
