When starting up a new online service, companies can find
many advantages when utilizing some of Amazon's AWS platforms. As an
experienced developer, I have used several of these services and can recommend
them to other people starting online services or dynamic websites.
AWS Managed Services India (AWS) began in
2002, leveraging the infrastructure already in place by one of the internet's
largest e-tailers. AWS provides a range of web services which can form what is
now becoming popularly known as a "cloud".
Currently on offer by AWS are approximately 20 web services
to be used in the cloud. The most popular to date are the Elastic Cloud Compute
and Simple Storage Service, respectively known as EC2 an S3.
S3
Perhaps the service which existing website owners can take
advantage of the quickest, is Amazon's Simple Storage Service (S3). S3 is an
online file storage system with built-in high redundancy and infinite
scalability. Amazon uses clusters of servers across the globe to guarantee up
to 99.999999999% retention and 99.99% up-time to any data you upload to S3.
Any existing files (up to 5GB in size per file) from a
website can be easily migrated to S3, allowing it to be used as a Content
Delivery Network (CDN). Amazon's AWS infrastructure resides on super fast
internet backbones, which means content will generally be served much faster
than if it were served from cheap shared hosting accounts. For the relatively
cheap price per GB of storage and data transfer, many website owners currently
using web hosting with limited storage and bandwidth may see instant cost
reductions by migrating to S3 for content delivery.
For large websites and online services which serve massive
amounts of data, the cost performance of Amazon's S3 can be very high and in
some cases a necessary tool when other services cannot store such large amounts
of data.
For a company considering starting up an online file sharing
or content-heavy service such as a photo or video sharing site, Amazon S3
offers many benefits and a performance which would otherwise require a large
initial cost outlay.
EC2
Amazon's Elastic Cloud Compute (EC2) is for server hosting
what S3 is for file storage - infinitely scalable and cost effective.
With EC2, you can setup your own cluster of virtual servers
running in AWS Managed Services India. You may
choose to run a single, low-power virtual server or a cluster of thousands of
high performance virtual servers, and any variation in between. Each server you
run is called an "instance" and you may choose to use an instance for
as little as one billable hour.
Being able to choose how long you use an instance, along
with how powerful it is, allows start-up companies to test a new powerful web
application without the need to provision costly hardware initially. This
alleviates a lot of the risk often encountered with web start-ups who must
calculate how much capacity they will need once the site becomes popular.
Under-estimating capacity can mean a disruption of service, over-estimating
will make the service less profitable.
The EC2 platform is totally programmable; too, which means
companies can build intelligent systems which will scale as capacity limits per
instance are encountered. When the server load is high, for example, more
instances can be turned on and share the load of the system. When the load
decreases, unneeded instances can be powered down, keeping costs and efficiency
steady.
Currently, there are various Windows and Linux Amazon
Machine Instances (AMIs) available for users to use as a starting point when
customizing their virtual servers. User-contributed AMIs is also available, with
purpose-built server configurations available.
