 What types of files are stored in the blobstore in TAS for VMs, and how can it be configured?
The Tanzu Platform for Cloud Foundry (TAS for VMs) is a comprehensive platform that supports the deployment and management of applications across various cloud environments. It includes a self-service application execution engine, an automation engine for application deployment, and lifecycle management, as well as a scriptable command line interface (CLI). TAS for VMs also integrates with development tools to streamline the deployment process.

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
The router in TAS for VMs 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 Tanzu Platform for Cloud Foundry Routing Architecture.

Authentication
The OAuth2 server (UAA) and Login Server work together to provide identity management in TAS for VMs.

App Lifecycle
The Cloud Controller (CC) directs the deployment of applications in TAS for VMs. 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 maintains 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.

Tanzu Platform for Cloud Foundry Architecture

The nsync, BBS, and Cell Rep components work together along a chain to keep apps running in TAS for VMs. 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:

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|>\nThe Tanzu Platform for Cloud Foundry (TAS for VMs) is a comprehensive platform that supports the deployment and management of applications across various cloud environments.
