Cloud Computing may not make sense for all application types. But as
with the adoption of commodity hardware and Linux over a decade ago,
economic considerations will continue to pressure adoption.
What types of applications do fit well in the cloud?
- Applications with Seasonal Traffic Patterns
- Proof-of-concept Applications
- Quick Temporary Dev & Test Environments
- CPU Intensive Applications
- On-Demand or Unknown Future Demand
Seasonal Traffic Patterns
applications often show the following traffic patterns. Traffic is
steady for weeks or months, then experiences a spike in traffic. That
spike may be due to a launch of a new product or service, a new
marketing or advertising campaign or sudden user interest. Inevitably
you'll need more servers and compute power to handle that spike. That
is your peak capacity requirement.
With traditional servers
you would need to buy enough servers or big enough ones to support that
load or else suffer outages. What's more you'd have to plan in advance
in order to have those servers online and integrated into the web
With Cloud Computing, you already
have spinup scripts for your server types, and can bring additional
compute power online with only a few commands. Even better with AWS
Autoscaling, you can define rules to have new servers spinup for you
you're in the process of testing a new business idea or internet
startup, you may not have the budget to order all sorts of heavy iron to
support it. Cloud Computing complements this type of requirement very
nicely. You need dev servers, voila they're up and running. Quickly
and cheaply. You may not know what you'll need in six months or if your
idea will take off, and don't have to risk a big purchase. Buy only
what you need.
Dev and Test Environments
application type that really complements cloud computing well is dev
and test environments. You may want to clone your production servers,
or bring on a temporary test environment with all of the same components
as production. But you don't need that setup all of the time. Just
bring the servers online when you need them and stop them when you're
done testing. You won't get instance charges while the servers are
stopped, but the server images will remain resident on your EBS
CPU Intensive Applications
farms are used for all sorts of applications such as SETI or the Human
Genome Project. These applications require legions of servers working
together to churn through large amounts of data. That are uniquely
fitted to cloud computing, as they are cpu-intensive. Once you are
done, you can easily decomission all of those servers.
gaming is another CPU intensive application. As users access Facebook
applications such as Farmville, it's hard to know in advance what those
demands will be from day-to-day. Enabling a feature like AWS
Autoscaling means the compute power does a lot of the capacity planning
for you, responding dynamically to need.
