The first easy-to-use, affordable small-screen tablet, the Amazon Kindle Fire is
revolutionary...
I can't emphasize this "ease of use" thing enough. More than anything else,
that's what's been
holding non-iPad tablets back. Amazon cracked it. End of story." - PC Mag

The Fire gives me the features I want at a price point that's less than half of
the iPad 2.
I can check my email, browse the Internet, maybe play a few games, most
importantly,
I can read magazines in color on a Kindle." - Gizmodo

"

Amazon’s Kindle Fire is likely to be the first successful tablet not sold by
Apple, and there
are several good reasons for it: the convenient, portable
size of 7 inches,
and a rich catalog of books, movies and music offered through Amazon’s Web-based
services." - Ars Technica

He strolled down Main Street and simply offered more than any other candidate,

Revolutionary Cloud-Accelerated “Split Browser”
Modern websites are complex. A typical web page requires 80 files served from 13
different domains. This takes a regular browser hundreds of round trips, and
adds seconds to page load times.
Amazon Silk is different in a radical new way. When you use Silk, without
thinking about it or doing anything explicit, you’re calling on the computing
speed and power of the Amazon Web Services cloud (AWS). We've refactored and
rebuilt the browser software stack to push pieces of the computation into the
AWS cloud. This lets Silk do more work, more quickly, and all at once. We call
this “split browser” architecture.
Silk browser software resides both on Kindle Fire and on the massive server
fleet that comprises the Amazon Elastic Compute Cloud (Amazon EC2). With each
page request, Silk dynamically determines a division of labor between the mobile
hardware and Amazon EC2 (i.e. which browser sub-components run where) that takes
into consideration factors like network conditions, page complexity and the
location of any cached content.
Shorter Transit Times
Amazon EC2 is always connected to the backbone of the Internet where round-trip
latency is 5 milliseconds or less to most web sites rather than the 100
milliseconds that’s typical over wireless connections. AWS also has peering
relationships with major internet service providers, and many top sites are
hosted on EC2. This means that many web requests will never leave the extended
infrastructure of AWS, reducing transit times to only a few milliseconds.
Computing Power in the Cloud
EC2 servers have massive computational power. On EC2, available CPU, storage,
and available memory can be orders of magnitudes larger than on mobile devices.
Silk uses the power and speed of the EC2 server fleet to retrieve all of the
components of a website simultaneously, and delivers them to Kindle Fire in a
single, fast stream. Transferring computing-intensive tasks to EC2 helps to
conserve your Kindle Fire battery life.
Persistent Connections
A typical web request begins with resolving the domain names associated with the
server and establishing a TCP connection to issue the http request. Establishing
TCP connections for each request consumes time and resources that slow down
traditional browsers. Silk keeps a persistent connection open to the backend
server on the AWS cloud so that there is always a connection at the ready to
start loading the next page. In addition, the Silk backend server keeps
persistent connections open to the top sites on the web. This approach further
reduces latency that would otherwise result from constantly establishing
connections. Further, the connection between Silk and the backend infrastructure
uses a pipelined, multiplexing protocol that can send all the content over a
single connection.
Page Indexes
Traditional browsers must wait to receive the HTML file in order to begin
downloading the other page assets. Silk is different because it learns these
page characteristics automatically by aggregating the results of millions of
page loads and maintaining this knowledge on EC2. While another browser might
still be setting up a connection with the host server, Silk has already pushed
content that it knows is associated with the page to Kindle Fire before the site
has even instructed the browser where to find it.
Machine Learning
Finally, Silk leverages the collaborative filtering techniques and machine
learning algorithms Amazon has built over the last 15 years to power features
such as “customers who bought this also bought…” As Silk serves up millions of
page views every day, it learns more about the individual sites it renders and
where users go next. By observing the aggregate traffic patterns on various web
sites, it refines its heuristics, allowing for accurate predictions of the next
page request. For example, Silk might observe that 85 percent of visitors to a
leading news site next click on that site’s top headline. With that knowledge,
EC2 and Silk together make intelligent decisions about pre-pushing content to
the Kindle Fire. As a result, the next page a Kindle Fire customer is likely to
visit will already be available locally in the device cache, enabling instant
rendering to the screen.
