Backlog

These are candidate features to consider for the roadmap.

• Create an issue to add a feature to this list.

API handling

• Implement a more advanced versioning system based on aspnet-api-versioning or comparable system. Current API versioning is very basic, simply based on the URLs.

Integration event messaging

• Azure Event Grid: Implement an additional Event Bus implementation based on Azure Event Grid.

Diagnostics and monitoring

• Monitoring/Diagnostics of microservices based on Application Insights with custom perfkeys.

• Semantic log - Semantic logic - Related to the Azure app version and Application Insight usage Monitor what microservices are up/down, etc. related to App Insights, but the events are custom ETW events and "Semantic Application Log" from P&P Multiple implementations for the storage of the events, Azure Diagnostics, Elastic Search. Using EventSource base class, etc.

• Create a new "ServerProblemDetails" response that conforms with RFC 7807, check issue #602 for details.

Orchestrators

• Service Fabric Stateful Service implementation in the SF branch

Front-end

• Support for .NET Core 2.0 Razor Pages as additional client app.

• Composite UI based on microservices. Including the “UI per microservice”.

  • Composite UI using ASP.NET (Particular’s Workshop)

  • The secret of better UI composition

  • Including Front-End Web Components Into Microservices

  • Managing Frontend in the Microservices Architecture
    http://allegro.tech/2016/03/Managing-Frontend-in-the-microservices-architecture.html

• Revamp the whole UI to a more modern look, with a CSS framework/template like CoreUI

• Explore Micro Frontends

Security

• Encrypt secrets at configuration files (like in docker-compose.yml). Multiple possibilities, Azure Key Vault or using simple Certificates at container level, Consul, etc.

• Other "secure-code" practices

• Encrypt communication with SSL (related to the specific cloud infrastructure being used)

• Implement security best practices about app's secrets (conn-strings, env vars, etc.) (However, this subject depends on the chosen orchestrator...) See when using Swarm: https://blog.docker.com/2017/02/docker-secrets-management/

• Support "multiple redirect urls" for the STS container based on Identity Server 4, check issue #113.

• Add social login to MVC and SPA apps, check issue #475 for details.

• Encrypt sensitive information, such as credit card number, along the ordering process, check issue #407

Resiliency

• Refactor/Improve Polly's resilient code, check issue #177 for details.

• Add a Jitter strategy to the Retry policy, check issue #188 for details.

Domain Driven Design

• Enhance the domain logic for Order Root-Aggregate.

  • Already implemented item stock validation (cancels order when quantity is not enough), but could add additional features, check issue #5.

• Handle validation results from MediatR's pipeline.

Testing

• Include some guidance on testing in CI/CD pipelines, check issue #549 for details.

• Create load testing alternative that's not dependent on the about-to-be-deprecated load testing feature of VS Enterprise, see issue #950 for more details.

Other

• Azure Functions integrated with Azure Event Grid: Additional event-driven Azure Function microservice (i.e. grabbing uploaded images and adding a watermark and putting it into Azure blobs) - The notification would come from Azure Event Grid when any image is uploaded into a BLOB storage.

• Gracefully stopping or shutting down microservice instances - Implemented as an ASP.NET Core middleware in the ASP.NET Core pipeline. Drain in-flight requests before stopping the microservice/container process.

• Create a building block to handle Idempotency in a generic way (Issue 143)

• Implement example of Optimistic Concurrency updates and optimistic concurrency exceptions

• Nancy: Add a Nancy based microservice, also with DocDB, etc.

• Support other DataProtection providers such as AspNetCore.DataProtection.ServiceFabric

• In the Windows Containers fork, implement and add a simple WCF microservice/container implementing any logic like a simulated legacy Payment Gateway, as an example of "lift and shift" scenario.

• Consider using Bash instead of PowerShell scripts, check issue #228 for details.

• Fix naming inconsistency in EventBus projects and namespaces, they should be EventBus.RabbitMQ" and "EventBus.ServiceBus", check issue #943

• Keep in mind incompatibilities between RabbitMQ and AMQP 1.0 when considering migration. See issue docs # 5672.
