LoopBack allows you to connect to many sources of data and services both in the
cloud and on-premise in your data center. DataSources are accessed through a
plugin called a Connector in LoopBack. Plugins are highly customizable and
extensible. Unlike other mobile backend, LoopBack can leverage your existing

data and organize them in the form of models.
Connectors implement the data exchange logic using database drivers or other

At first glance, LoopBack looks like just any other API tier. But
looks can be deceiving. Here are some key differentiators that make
Loopback stand out as an api tier built for mobile:
1. Model APIS are surfaced over REST without writing code
2. The Datasource Juggler is modern ORM that supports supports
not only traditional RDBMS, but also noSQL and services
3. As a mobile backend as a service (mBaaS) we help you leverage
valuable existing data in your mobile app as well dynamically create
new schema or schemaless data
<h4> Mobile clients </h4>
We're putting a lot of effort into building flexibility and
functionality into our mobile client SDKs. The ultimate goal is to
preserve what's familiar to the mobile developer in their native
platform and empower them with seamelss backend functionality.
All mobile clients call into the mobile API tier through REST.
Protocol binding within LoopBack actually has a plugin architecture
so that you can switch to websockets for example for more real time
capabilities in the future.
<h4> API Gateway </h4>
The first line of defense and entry is the API gateway. This
sub-component of LoopBack acts as a reverse-proxy to the rest of
LoopBack. It provides OAuth2 base security, will mediate between
multiple data formats and acts as a quality of service layer for your
API providing instrumentation and other aspect level functionality.
<h4> API Server </h4>
The core of LoopBack is the API Server where models are registered
and hosted during runtime. Models are automatically exposed through a REST endpoint.
The API server also will run batch processes or scheduled jobs as a
mobile backend for functions like mass push notifications.
<h4> Enterprise Connectors </h4>
LoopBack lets you leveratge existing data and services that you need
in your mobile apps just as you do in your web apps. LoopBack has a
layer of abstraction provided by the DataSource Juggler so that all
you need to worry about is your model. The Datasource Juggler
accesses the underlying [datasources](http://docs.strongloop.com/loopback/#data-sources-and-connectors) through Enterprise
Connectors.
<h4> Editor </h4>
LoopBack comes with a rich set of [Node.js based APIs](http://docs.strongloop.com/loopback/#nodejs-api).
The editor is a web based GUI that makes it even easier to define,
configure and manage your mobile apps and models without having to
write code. The editor will also facilitate the process of
[discovering models](http://docs.strongloop.com/loopback/#datasourcediscovermodeldefinitionsusername-fn) and [schemas](http://docs.strongloop.com/loopback/#datasourcediscoverschemaowner-name-fn)
from datasources to give you a headstart on building your app.
<h4> Admin Console </h4>
Each LoopBack development environment is fully self contained. When
working in the enterprise, there is a need to distribute work much
like how distributed source control systems like `git` have risen and
evolved. When combining the work ouput from multiple LoopBack
development environments into a single enterprise runtime, the Admin
Console helps with merging and maintaining configuration as well as
deployment.
<h4> Repository </h4>
All development in LoopBack ends up as metadata that's stored in JSON
config files. Config files are distributed, merged and
consolidated centrally into the Repository. The Repository is
centrally maintained by an admin through the [Admin
Console](http://docs.strongloop.com/loopback#admin-console) where
policies like security are defined and configured.
<h4> LoopBack Node.js API </h4>
All manipulation of the metadata that constitutes the entire runtime
of the mobile API is done through an internal Node.js API. In the
spirit of truly "eating our own dog food" - the API powers the
editor and any other tools that are included with LoopBack.
