When you install FastAPI, it comes with a production server, Uvicorn, and you can start it with the `fastapi run` command.

But you can also install an ASGI server manually.

Make sure you create a [virtual environment](../virtual-environments.md){.internal-link target=_blank}, activate it, and then you can install the server application.

For example, to install Uvicorn:

<div class="termy">

	}
	obj, err := api.GetObjectInfo(ctx, r.Bucket, objInfo.Name, opts)
	if err != nil {
		return err
	}
	oi := obj.Clone()
	var (
		newKeyID      string
		newKeyContext kms.Context
	)
	encMetadata := make(map[string]string)
	for k, v := range oi.UserDefined {
		if stringsHasPrefixFold(k, ReservedMetadataPrefixLower) {
			encMetadata[k] = v
		}
	}

	if (sseKMS || sseS3) && r.Encryption.Type == ssekms {

 the version number 2.1.)

For large responses, returning a `Response` directly is much faster than returning a dictionary.

This is because by default, FastAPI will inspect every item inside and make sure it is serializable as JSON, using the same [JSON Compatible Encoder](../tutorial/encoder.md){.internal-link target=_blank} explained in the tutorial. This is what allows you to return **arbitrary objects**, for example database models.

	// Externally, Next iterates through the tar archive as if it is a series of
	// files. Internally, the tar format often uses fake "files" to add meta
	// data that describes the next file. These meta data "files" should not
	// normally be visible to the outside. As such, this loop iterates through
	// one or more "header files" until it finds a "normal file".

// and also that small branches with few objects don't take up unreasonable amounts of space.
// This keeps the cache size at a reasonable size for all buckets.
//
// Whenever a branch is scanned, it is assumed that it will be un-compacted
// before it hits any of the above limits.
// This will make the branch rebalance itself when scanned if the distribution of objects has changed.

// - Range over all the available buckets

// -- If yes, check if the entry matches local IP check if we
//
//	need to update the entry then proceed to update
