Jury v2 Architectural Roadmap

Jury v2 Architectural Roadmap

Executive Summary 

The Jury v2 software architectural roadmap focuses on modernizing the technology stack, enhancing performance and scalability, and improving security. The current architecture utilizes Angular v16, .NET 6, and various other technologies, deployed in a containerized environment on AWS. Key initiatives include upgrading to Angular v17, implementing permissions, building out a domain layer, and securing sensitive information with AWS Secrets Manager. The roadmap aims to address technical debt, improve system reliability, and ensure compliance with security standards. 

Current Architecture 

The information below details the technologies used in Jury v2 and describes the environment in which Jury v2 is deployed. 

Technology Stack 

  • Front-end:  

    • Angular v16: UI framework developed by Google  

    • Angular Material v16: Prebuilt UI Components developed for use in Angular 

    • Tailwind CSS v3.4.1: Library used to style HTML elements 

    • Authentication:  

      • OpenID Connect (OIDC): industry standard authentication protocol 

      • JSON Web Tokens (JWT): industry standard security token format 

      • Back-end For Front-end (BFF) Encryption Layer: secure client token management library developed by Duende Software  

      • Microsoft ASP.NET Core authentication libraries: latest encryption/decryption/verification libraries provided by Microsoft 

  • Back-end:  

    • Microsoft .NET v6 with C# v10 

    • Command Query Responsibility Segregation (CQRS): Separates the concerns of the Command (create, update, and delete) operations from the Query(read) operations 

    • Dapper: An object relational mapping (ORM) library which simplifies the create, read, update, and delete (CRUD) operations on the database by automatically mapping database parameters and data results to C# objects 

    • Fluent Validation:  A library which allows developers to easily implement complex validation rules on all data sent to the API 

    • MediatR: an in-memory bus which implements a publisher/subscriber (Pub/Sub) used to loosely couple the API layer to the Application Layer 

    • NodaTime: A date time management library used to extend the limited date time functionality provided by the .NET framework. Usage of frameworks such as this are key when implementing multi-tenant solutions as tenants and users are dispersed throughout the world and rarely in the same time zone as the servers. 

    • QuestPDF: This is a newly developed open-source library which is used to generate PDF documents using C#. A few reports were built using this technology, but we may phase them out and implement more current versions of the reporting tools (Aspose and ActiveReports) used in Jury v1. 

    • Aspose: Reporting / Document generation library used to build PDF documents from templates which can be defined by users 

    • ActiveReports: A reporting solution used to generate listings or statistical reports 

    • Twilio: This library enables the application to send SMS Messages to Jurors  

    • Authentication:  

      • OpenID Connect (OIDC) - industry standard authentication protocol 

      • JSON Web Tokens (JWT) - industry standard security token format 

      • Microsoft ASP.NET Core authentication libraries – latest encryption/decryption/verification libraries provided by Microsoft  

  • Database: Microsoft SQL Server 

  • Document Storage: Amazon S3 

Deployment Architecture  

When deployed, the application has the following AWS Footprint:  

  • 3 Kubernetes Containers 

  1. Front-end: 

    1. OS: Debian Linux v11 

    2. Server: Microsoft Kestrel Web Server 

    3. Frameworks: ASP.NET Core 6.0 

    4. Utilization: Always On 

  2. Back-end:  

    1. OS: Debian Linux v11 

    2. Server: Microsoft Kestrel Web Server 

    3. Frameworks: ASP.NET Core 6.0 

    4. Utilization: Always On 

  3. Database Updater: 

    1. OS: Debian Linux v11 

    2. Application: .NET Core 7.0 Console Application 

    3. Frameworks: .NET SDK 7.0 

    4. Utilization: Deployment Only 

  • 1 AWS RDS Server running SQL Server Engine 

    • 1 Master Database 

    • 1 Database per Tenant  

  • 1 S3 Bucket per Tenant for Document Storage 

Assessment of system scalability, performance, and reliability 

  • Scalability: Although the application is deployed in a containerized manner, preliminary work has not yet been done to ensure the application can run in a scaled environment (multiple containers). Further research is needed to determine if we may need to implement a framework such as Redis or Amazon ElastiCache to share information between servers. 

  • Database Performance: The database structure from Jury v1 has remained largely unchanged through Jury v2. As such, all performance improvements in the v1 database are contained in the v2 database. In addition, the database auditing mechanism utilized in Jury v1 was replaced in Jury v2 which removed over 300 complex triggers. 

  • Application Performance: Jury v1 and Jury v2 are both built upon the .NET framework and all algorithms present in the Jury v1 application were ported to the Jury v2 application 

  • Database Reliability: Failover Groups will have to be implemented on the database implementation to provide for additional database servers to spool up should the servers hosting the databases fail. 

  • Application Reliability: As mentioned above in the scalability section, research is still needed into replicating containerized instances of the application. This work will yield information on what enhancements are required to seamlessly float containers across AWS Availability Zones in case of outages. 

Identification of architectural bottlenecks and pain points 

  • While Jury v2 does follow the CQRS pattern, there is no Domain Layer. Business Logic which should be contained within Domain Objects are spread throughout various Command Handlers. This causes duplication of code and is not considered clean architecture. 

  • A framework to implement permissions exists in the backend however no code utilizes this framework. This means all API endpoints and all UI screens and features can be accessed by all users regardless of their configured permissions. 

Evaluation of Security Posture

  • User authentication in Jury v2 was originally handled by a custom ASP.NET Identity solution implemented within the front-end and back-ends of the application. This custom solution was removed from Jury v2 and replaced with a much more secure integration to Duende Identity Server. This change allowed us to rip out thousands of lines of complex authorization/authentication code from both the front-end and the back-end. 

  • Front-End security: Each request for a Web Page must contain an encrypted User Access Token which is decrypted and validated by the BFF layer before being allowed to pass to the Web Server.  

  • Back-End security: Each request to an API Endpoint must contain an encrypted User Access Token which is decrypted and validated by the BFF layer before being allowed to pass to the API Server. 

  • Jury v2 is regularly monitored by SonarQube and any code security issues are addressed as they arise. 

  • Jury v2 will soon also be monitored by Qualys and any security vulnerabilities will be addressed as they arise 

  • Database security: Currently the Jury v2 application uses a connection string with a user account containing a username and password to access the database. This should be updated to remove the user account from the connection string. Instead, the API application should be running under an AWS service account and this service account should be given access to the database. This would prevent someone from using the username and password found in the connection string to access the database. 

Review of development and deployment processes 

  • Development Process:  

    • Each development task is performed on a fork of the master branch 

    • A Pull Request (PR) is created by the developer for review by a senior team member 

    • The PR is merged into the master branch 

  • Development Process Issues: 

    • Due to a lack of deployment environments, work cannot be verified by a QA or UX resource without first checking the code into the master branch. This results in potentially broken functionality being placed into the master branch.  

    • Due to a shortage of resources assigned to the project, Pull Requests require only 1 reviewer instead of the standard 2 reviewers.  

  • Deployment Process:

    • Deployment is limited as it currently only deploys to a single environment named Dev.  

  • Deployment Process Issues:  

    • Multiple deployment pipelines should be created so different features of the application can be deployed to different environments such as Test1, Test2, and Test3, etc. In addition, Release Candidate versions of the application should be deployed to Preview or Staging environments and analyzed before being pushed to Production. While there is a QA environment that exists, it shares the same database as Dev so it is not a true standalone environment. 

Vision and Goals 

This section describes some of the shortcomings of the Jury v2 application currently being developed. The following items describe those areas and include steps to resolve the issues. 

Domain Implementation

While Jury is being developed using modern technologies, there is room for improvement in the way these technologies have been implemented.  In a rush to refresh the look and feel of the front-end, little planning was put into the internal architecture of the back end. As such the back end of the application does not conform to clean architecture principles. Currently the Application Layer (API) directly calls into the Persistence Layer (Database).  This implementation lacks a Domain Layer to centralize business logic into Domain Objects. The biggest negative impact of this design is code duplication. Instead of having a single class that implements logic to perform some task in the application, this logic can be implemented in several different places and in several different ways. Obviously this increases the complexity of implementing new features and increases the amount of code that must be tested. To address this problem, a single area of the application should be selected and rewritten to utilize domain objects in a domain layer. Once a few examples of this architecture have been created and demonstrated, this design pattern can be used to improve existing features and replicated when creating new features.

Containerization and Scaling

The Jury application consists of a front-end and back-end that can be deployed separately and thus lend themselves to containerization. Jury is currently deployed as two containers into a Kubernetes cluster in AWS. This gives us a great head start towards the ability to horizontally scale into multiple containerized instances to handle increased workloads. There is work that remains to be done, however, to ensure this works correctly. For example, tools such as Redis Cache or Amazon ElastiCache should be implemented so that cached data can be shared between instances of the container. In the future if smaller containers are needed, it would require minimal effort to move the BFF Authentication to its own container, and to split the API into separate containers. 

Security

There is a security framework in place inside the Jury back-end but this security framework is not yet being utilized. In the coming months this security framework must be implemented using the existing permission roles settings. This will allow locking down each API endpoint in the back-end and allow locking down each screen/menu option in the front-end. Examples of security implementation in the back-end and security implementation in the front-end must be done as examples for the developers. Once these examples are in place the functionality can be replicated throughout the application. 

Sensitive Data

Deployment of the Jury application is now being done using core scripts provided by DevOps. These scripts have since been updated by those working on the deployment of Jury to contain sensitive information such as database connection strings, S3 bucket secret keys, and Twilio secret keys, all in plain text.  Jury v2 must be enhanced to contain code to retrieve this information at runtime from a sensitive storage location such as AWS Secrets Manager. Once this code is in place, all sensitive information can be removed from the scripts and placed into the secrets store. DevOps can then manage access to this resource instead of storing this information in the deployment scripts. 

Automated Testing

Currently there is no automated testing occurring when the Jury application is built or deployed. There are examples of other products which use a combination of modern testing tools such as Playwright and SpecFlow to produce detailed reports about the source code quality. These testing technologies make use of natural languages such as Gherkin to create tests which match up to User Stories from the backlog. A good example of a Gherkin test case would be “When a new Summons is Drawn, a new Jury Pool should be Created".  Playwright utilizes SpecFlow to transform this natural language into a testing scenario and execute the test. Detailed artifacts are then created from the outcome of these tests and can be reviewed and acted upon immediately. 

Deployment

In addition to implementing automated testing inside the CI/CD pipeline, multiple environments and the ability to deploy directly to them must also be introduced. Existing are some scripts to promote deployments through the environments such as Dev to QA to Staging to Production. However, this process does not include the concept of frozen Releases or provide for the ability to release a version directly to an environment. For example, on March 1st version 2.1.1 could be frozen and deployed to the QA environment. After some initial testing this version would then be promoted to Staging. In the meantime, a developer may have deployed a new feature that belongs in version 2.2.0 to the QA server for testing. If there is a bug found in version 2.1.1 of the Staging environment, that bug could be fixed, but there is no way to deploy version 2.1.2 back to the Staging environment. This bug fix would have to first be deployed to Dev then to QA then to Staging interrupting all work that is being done on the next version 2.2.0 in the QA environment. 

Architectural Principles 

Following are industry established architectural principles to be followed when designing new functionality for the application:  

  • Modularity: Composed discrete, interchangeable modules with well-defined interfaces, promoting reusability, maintainability, and ease of understanding. 

  • Scalability: Architect features to scale horizontally and vertically to accommodate growing user bases and increased workloads, leveraging distributed systems and efficient resource utilization. 

  • Loose Coupling: Minimize dependencies between components to reduce the impact of changes and facilitate independent development, testing, and deployment of modules. 

  • High Cohesion: Ensure that each module or component has a clear, focused purpose and functionality, promoting better maintainability, testability, and understanding of the codebase. 

  • Separation of Concerns: Divide the application into distinct layers or components, each responsible for a specific aspect of functionality (e.g., presentation, business logic, data access), to improve modifiability and clarity of design. 

  • Security by Design: Integrate security measures and best practices into the architecture from the outset, including authentication, authorization, encryption, and secure communication protocols, to protect against potential threats and vulnerabilities. 

  • Performance Optimization: Architect the application to be performant by employing efficient algorithms, data structures, caching mechanisms, and optimization techniques to minimize latency, maximize throughput, and optimize resource utilization. 

  • Flexibility and Extensibility: Design the application to accommodate future changes and enhancements by adopting flexible, extensible architectures and design patterns that allow for easy integration of new features, modules, and technologies. 

  • Resilience and Fault Tolerance: Build the application to withstand and recover gracefully from failures, errors, and unexpected events by implementing fault-tolerant mechanisms, redundancy, graceful degradation, and automated recovery processes. 

  • Testability: Ensure that the application is designed for ease of testing, with clear separation of concerns, modular architecture, and support for automated testing frameworks and tools to facilitate comprehensive testing and validation of functionality. 

  • Simplicity and Minimalism: Strive for simplicity in design and implementation, favoring straightforward solutions over overly complex ones, to reduce cognitive overhead, minimize technical debt, and improve maintainability. 

  • Adaptability to Change: Architect the application to be adaptable and responsive to changing business requirements, technological advancements, and user feedback, enabling iterative development, continuous integration, and delivery practices.
