How can I manage crash-inducing traffic spikes
my website?
First
, congratulations--this is a good problem to have. Maybe a new product on your retail website got big media
. Suddenly your online traffic jumped sevenfold, and 90 minutes
, your site
down, the victim of too many consumers trying to access
product.
What could
prevented this catastrophe is a content delivery network (CDN) from Akamai, Amazon, CDNetworks or one of the many
providers worldwide. It's a cloud-based automatic scaling service designed
optimize the delivery of
content--most commonly software and video--to your customers
the most reliable fashion. With a CDN
place, customers can access your site no
how many visitors have the same idea at the same
. And they can quickly download your content
they're across town or halfway
the world.

Who needs a CDN?
If your consumer base is distributed
a wide geographic area, or if you have predictable online traffic patterns--for
, you know Cyber Monday and Mother's Day are big days--or concerns
unexpected flash crowds due to content or a promotion, you need a CDN. If you require online speed to compete
rivals, as you would with online shopping services or travel reservations,
need a CDN. If your concern is a denial of service or cyber attacks, you,
, need a CDN.
Who doesn't need one?
If your business is regional with a focus
local customers, you might not need
. If your website's revenue isn't tied
its performance, or if you have
global audience or no chance of showing
on Yahoo News, you don't need a CDN.
How do you choose a CDN?
If your network is
serve, say, the Chinese market, you'll want a CDN
a Chinese presence to add stability. You'll
need to know if the CDN will support your application and
your goals. And ask your short list of providers
they're willing to
a head-to-head test using your application and content.
How much do CDNs charge?
If yours is a video delivery site, you'll likely
charged in GBT (gigabytes transferred) or Mbps (megabits
second). If you have a shopping site or advertising application, costs may
by transaction, page views or other metrics related
your application. The prices per data delivery or transaction requests are
fractions of a penny, but when you're talking
millions of people flooding your site,
in mind that it can quickly add
to real money.
How fast can a CDN be
into place?
With a good provider, once the terms are ironed
, turning it on can
just a few minutes. However, complicated applications can take a few days or weeks
configure. Give yourself at
one month to sort out what you need and
you'll use so you can
sure you're getting a good deal.
