+### Controller
 
-Controller
+The controller contains CRUD APIs for functions, triggers, environments,

+However, PoolManager only selects one pod per function, which is not
+suitable for serving massive traffic. In such cases, you should consider
+using NewDeploy as executor type of function.
+
+[1] The cold start time depends on the package size of the function. If it's
+a snippet of code, the cold start time usually is less then 100ms.
+
+#### NewDeploy 
+
+NewDeploy creates deployment, service, and HPA for functions in order to handle 
+massive traffic.
+
+NewDeploy watches the function CRD changes and creates a Kubernetes deployment, 
+service, and HPA for a function. NewDeploy will scale the replicas of a function 
+deployment to the minimum feasible scale setting, if the minimum scale setting of 
+a function is greater than 0. The 'fetcher' inside the pod uses a URL in the 
+JSON payload, which is attached as a parameter to start fetcher, to download the 
+function package instead of waiting for calls from NewDeploy. 
+
+When a function experiences a traffic spike, the service helps to distribute the requests to 
+pods belonging to the function for better workload distribution and lower latency. Also, 
+the HPA scales the replicas of the deployment based on the conditions set by the user.
+ 
+This approach though increases the cold time of a function, but also makes NewDeploy 
+suitable for functions designed to serve massive traffic.
+
+### Environment Container
+
+Environment containers run user-defined functions and are language-specific. 
+Each environment container must contain an HTTP server and a loader for functions.
+
+The pool manager deploys the environment container into a pod with fetcher 
+(fetcher is a simple utility that can fetch an HTTP URL to a file at a 
+configured location). This pod forms a "generic pod" because it can
+be loaded with any function in that coding language.
+
+When the pool manager needs to create a service for a function, it calls
+fetcher to fetch the function. Fetcher downloads the function into a
+volume shared between fetcher and this environment container. Poolmgr
+then requests the container to load the function.
+
+### Router
+
+The router forwards HTTP requests to function pods. If there's no
+running service for a function, it requests one from executor, while
+holding on to the request; the router will forward the request to 
+the pod once the function service is ready.
+
+The router is the only stateless component and can be scaled up if needed, according to
 load.
 
-Kubewatcher
+### Builder Manager
------------
+
+The builder manager watches the package & environments CRD changes and manages 
+the builds of function source code. Once an environment that contains a builder 
+image is created, the builder manager will then creates the Kubernetes service 
+and deployment under the fission-builder namespace to start the environment 
+builder. And once a package that contains a source archive is created, the 
+builder manager talks to the environment builder to build the function's source 
+archive into a deploy archive for function deployment.
+
+After the build, the builder manager asks Builder to upload the deploy archive to the 
+Storage Service once the build succeeded, and updates the package status attached with build logs.
+
+### Storage Service
+
+The storage service is the home for all archives of packages with sizes larger than 256KB.
+The Builder pulls the source archive from the storage service and uploads deploy archive to it.
+The fetcher inside the function pod also pulls the deploy archive for function specialization.
+
+## Optional Components
+
+### Logger
+
+Logger is deployed as DaemonSet to help to forward function logs to a centralized 
+database service for log persistence. Currently, only InfluxDB is supported to store logs.
+
+Following is a diagram describe how log service works:
+1. Logger watches pod changes and creates a symlink to the container log if the pod runs on the same node.
+2. Fluentd reads logs from symlink and pipes them to InfluxDB
+3. `fission function logs ...` retrieve event logs from InfluxDB with optional log filter
+4. Logger removes the symlink if the pod no longer exists.
+
+### Kubewatcher
 
 Kubewatcher watches the Kubernetes API and invokes functions
 associated with watches, sending the watch event to the function.

+# Fission: Tensorflow Serving Environment
+
+This is the Tensorflow Serving environment for Fission.
+
+It's a Docker image containing a Go runtime, along with a tensorflow serving service.
+
+## How it works
+
+Tensorflow Serving is an serving service that supports both RESTful API and gRPC endpoints. In current implementation,
+Go server launches `tensorflow_model_server` to load in model during specialization. As long as the Go server receives
+requests from router it creates a reverse proxy that connects to RESTful API endpoint exposed by tensorflow_model_server
+and get response from the upstream server for user.
+
+## Build this image
+
+```
+docker build -t USER/tensorflow-serving . && docker push USER/tensorflow-serving
+```
+
+## Using the image in fission
+
+You can add this customized image to fission with "fission env create":
+
+```
+fission env create --name tensorflow --image USER/tensorflow-serving --version 2
+```
+
+After this, fission functions that have the env parameter set to the
+same environment name as this command will use this environment.

-	goapp get github.com/golang/example/appengine-hello
-
-A trivial "Hello, world" App Engine application intended to be used as the
-starting point for your own code.
-
-_Note_: The `goapp` tool is part of the [Google App Engine SDK for Go](https://cloud.google.com/appengine/downloads#Google_App_Engine_SDK_for_Go).
-
-### [gotypes](gotypes/) ([godoc](//godoc.org/github.com/golang/example/gotypes))
-
-The `go/types` package is a type-checker for Go programs. It is one of the most
-complex packages in Go's standard library, so we have provided this tutorial to
-help you find your bearings. It comes with several example programs that you
-can obtain using `go get` and play with as you learn to build tools that analyze
-or manipulate Go programs.
-
-### [template](template/) ([godoc](//godoc.org/github.com/golang/example/template))
-
-A trivial web server that demonstrates the use of the
-[`template` package](https://golang.org/pkg/text/template/)'s `block` feature.

-This code is a starting point for your Google App Engine application in
-Go.
-
-To run the application locally you need the install the [Go Cloud
-SDK](https://cloud.google.com/appengine/docs/go/#Go_tools) and execute the next
-command from the directory containing this file:
-
-    $ goapp serve app.yaml
-
-To deploy the application you have to first create an App Engine project
-and use it as the application file in all the yaml files.
