 Authentication and Identity Management: Discuss the role of the OAuth2 server (UAA) and Login Server in providing identity management for TAS for VMs.
\nIn the realm of TAS for VMs, the OAuth2 server (UAA) and Login Server are pivotal in establishing a robust identity management framework. This framework is essential for ensuring that users can securely access and manage applications within the Tanzu Platform for Cloud Foundry environment. The OAuth2 server, known as UAA, acts as the central authority for authentication and authorization. It issues tokens to users after they have successfully authenticated themselves, which can then be used to access various resources within the platform.

The Login Server complements the UAA by providing a user-friendly interface for users to log in. It simplifies the authentication process by allowing users to sign in using their existing credentials from other services, such as Google or Facebook, through the OAuth2 protocol. This integration enhances the user experience by reducing the need for users to create and remember multiple sets of credentials for different applications.

Together, the UAA and Login Server form a comprehensive identity management system that supports secure, seamless access to applications. They enable the Tanzu Platform for Cloud Foundry to offer a flexible and user-friendly environment for developers and users alike, facilitating the deployment, management, and scaling of applications across various cloud infrastructures.

Also, an integration with development tools to ease deployment processes. TAS for VMs has an open architecture that includes a buildpack mechanism for adding frameworks, an application services interface, and a cloud provider interface.

Routing
Router
The router routes incoming traffic to the appropriate component, either a Cloud Controller component or a hosted application running on a Diego Cell.

The router periodically queries the Diego Bulletin Board System (BBS) to determine which cells and containers each application currently runs on. Using this information, the router recomputes new routing tables based on the IP address of each cell virtual machine (VM) and the host-side port numbers for the cell’s containers.

For more information about the routing tier, including the router, see TAS for VMs Routing Architecture.

Authentication
OAuth2 Server (UAA) and Login Server
The OAuth2 server (the UAA) and Login Server work together to provide identity management.

App Lifecycle
Cloud Controller and Diego Brain
The Cloud Controller (CC) directs the deployment of applications. To push an app to TAS for VMs, you target the Cloud Controller. The Cloud Controller then directs the Diego Brain through the CC-Bridge components to coordinate individual Diego cells to stage and run applications.

The Cloud Controller also maintain records of orgs, spaces, user roles, services, and more.

nsync, BBS, and Cell Reps
To keep applications available, cloud deployments must constantly monitor their states and reconcile them with their expected states, starting and stopping processes as required.

TAS for VMs Architecture

The nsync, BBS, and Cell Rep components work together along a chain to keep apps running. At one end is the user. At the other end are the instances of applications running on widely-distributed VMs, which might crash or become unavailable.

Here is how the components work together:

nsync receives a message from the Cloud Controller when the user scales an app. It writes the number of instances into a DesiredLRP structure in the Diego BBS database.
BBS uses its convergence process to monitor the DesiredLRP and ActualLRP values. It runs or stops application instances as appropriate to ensure the ActualLRP count matches the DesiredLRP count.
Cell Rep monitors the containers and provides the ActualLRP value.
App Storage and Execution
Blobstore
The blobstore is a repository for large binary files, which Github cannot easily manage because GitHub is designed for code. The blobstore contains the following:

Application code packages
Buildpacks
Droplets
You can configure the blobstore as either an internal server or an external S3 or S3-compatible endpoint. For more information about the blobstore, see How to use Elastic Runtime BLOB Storage Data in the Knowledge Base.

Diego Cell
Application instances, application tasks, and staging tasks all run as Garden containers on the Diego Cell VMs. The Diego cell rep component manages the lifecycle of those containers and the processes running in them, reports their status to the Diego BBS, and emits their logs and metrics to Loggregator.

Services
Service Brokers
Applications typically depend on services such as databases or third-party SaaS providers. When a developer provisions and binds a service to an application, the service broker for that service is responsible for providing the service instance.

Messaging
Internal HTTPS and BBS
The component VMs of TAS for VMs communicate with each other internally through HTTP and HTTPS protocols, sharing temporary messages and data stored in Diego’s Bulletin Board System (BBS).\n<|end|>\n<|copywriter|>\n\nIn the realm of TAS for VMs, the OAuth2 server (UAA) and Login Server are pivotal in establishing a robust identity management framework.
