Multi-Tenant EVault Architecture Transition
Description
Alright, guys, let's dive into the exciting transition from our current individual Pod-based eVault setup to a shiny new Multi-Tenant architecture. This move is all about making things more efficient, scalable, and easier to manage. Instead of having separate Pods for each user or small group of users, we're consolidating resources into a shared environment. Think of it like moving from individual apartments to a well-managed apartment building – everyone gets their space, but the overall infrastructure is shared and optimized. You can find more detailed information about the specifics of this transition at this link. This document provides a comprehensive overview of the project's goals, technical details, and implementation strategy. Understanding this document is crucial for anyone involved in the transition, as it lays out the foundation for all the changes we'll be making.
This transition is a significant undertaking that will impact various aspects of our system. From resource allocation to data management, every component needs to be carefully considered and adapted to the new architecture. The goal is not just to migrate existing functionality but also to enhance performance, improve security, and reduce operational overhead. By adopting a Multi-Tenant approach, we aim to achieve better resource utilization, simplified management, and increased scalability. This will enable us to accommodate future growth and adapt to changing business needs more effectively. The key to a successful transition lies in meticulous planning, thorough testing, and close collaboration between all teams involved. We need to ensure that the new architecture is robust, reliable, and meets the evolving demands of our users. This involves not only technical changes but also process adjustments and training to ensure that everyone is comfortable and proficient with the new system. In essence, this transition is a strategic investment in the future of our eVault infrastructure, paving the way for greater efficiency, scalability, and innovation.
Acceptance Criteria
To make sure we're all on the same page and that this transition is a resounding success, we've got some key acceptance criteria that we need to meet. These criteria will serve as our benchmarks for ensuring that the new Multi-Tenant eVault architecture is functioning as expected and delivering the benefits we're aiming for. Let's break down each criterion:
Map One User Per Port (TBD)
First up, we need to figure out how to map users to ports in this new setup. The details are still "To Be Determined" (TBD), but the basic idea is that each user will be assigned a specific port. This is important for network management and security, allowing us to control and monitor traffic on a per-user basis. We need to figure out the best way to implement this mapping, considering factors like scalability, performance, and ease of management. This might involve changes to our networking infrastructure, configuration management, and user authentication systems. The goal is to create a system that is both secure and efficient, allowing us to handle a large number of users without compromising performance. We'll need to conduct thorough testing to ensure that the mapping is working correctly and that there are no conflicts or performance bottlenecks. This criterion is crucial for ensuring that the new architecture is scalable and can accommodate future growth.
Move PVC Out of eVaults
Next, we're moving Persistent Volume Claims (PVC) out of the eVaults themselves. This means that instead of each eVault managing its own storage, the storage configuration will be handled at the environment level. Think of it as decoupling the storage from the application. This approach gives us more flexibility in how we manage storage resources and allows us to optimize storage utilization across the entire environment. By externalizing the PVC configuration, we can easily scale storage resources as needed and adapt to changing storage requirements. This also simplifies the management of storage policies and ensures consistency across all eVaults. The number of users mapped to a single database instance becomes an environment configuration issue, rather than being tied to the eVault itself. This separation of concerns makes the system more modular and easier to manage. It also allows us to leverage different storage technologies and configurations for different environments, depending on their specific needs. The implementation of this criterion requires careful coordination between the storage, networking, and application teams to ensure that the transition is seamless and that there are no data loss or performance issues.
Make eVault Software Completely Stateless
We're aiming to make the eVault software completely stateless. Statelessness means that the eVault doesn't store any persistent data or session information. All the necessary data is passed to the eVault with each request, and the eVault doesn't rely on any previous state. This makes the system more resilient, scalable, and easier to manage. Stateless applications can be easily scaled horizontally by adding more instances, and they are less prone to failures due to state corruption or inconsistencies. By making the eVault software stateless, we can simplify deployment, reduce operational overhead, and improve the overall reliability of the system. This requires a careful review of the existing codebase to identify any stateful components and refactor them to be stateless. We also need to ensure that all data is stored externally, such as in a database or cache, and that the eVault can access this data as needed. The transition to a stateless architecture is a significant undertaking that requires careful planning and execution, but it is essential for achieving the scalability and resilience we need in the new Multi-Tenant environment.
Add eName to Metadata of a MetaEnvelope
Finally, we're adding an eName field to the metadata of a MetaEnvelope. The eName will likely represent the environment name or some other identifier that helps us distinguish between different environments. This is important for tracking and managing data across multiple environments. By including the eName in the metadata, we can easily identify the origin of a MetaEnvelope and ensure that it is processed correctly. This also simplifies debugging and troubleshooting, as we can quickly trace the flow of data through the system. The implementation of this criterion involves updating the MetaEnvelope data structure to include the eName field and ensuring that all components that create or process MetaEnvelopes are updated to handle this new field. We also need to ensure that the eName is properly validated and that it is consistent across all environments. This change may seem small, but it has significant implications for data management and traceability in the new Multi-Tenant environment.
In conclusion, these acceptance criteria are designed to ensure that the transition to a Multi-Tenant eVault architecture is successful and that the new system meets our requirements for scalability, reliability, and manageability. Each criterion addresses a specific aspect of the transition, and together they provide a comprehensive framework for evaluating the success of the project. By meeting these criteria, we can ensure that the new architecture is a significant improvement over the existing system and that it provides a solid foundation for future growth and innovation.
