Amazon Web Services (AWS) opening a data center in Singapore to make its entry in the Asia Pacific region has created a lot of interest about Amazon Elastic Compute Cloud (Amazon EC2) in India. As a leading public cloud computing provider, AWS falls in the infrastructure as a service (IaaS) space, providing on demand service using virtual server instances with unique IP addresses and blocks of storage. This is why AWS pricing, specifically

Amazon
EC2 pricing models, are generating significant amounts of curiosity.

To have quick overview, AWS includes various components like Amazon EC2, Amazon Simple Storage
Service (Amazon S3), Amazon SimpleDB, Amazon Relational Database Service (Amazon RDS). AWS overall,
and Amazon
EC2 pricing models in specific, follow a pay-as-you-go model (as in any other cloud computing
model). With regards to latency, Amazon claims that there will hardly be any cause of concern since
AWS now has its data center in Singapore.
In the entire AWS portfolio, Amazon EC2 remains the most popular service. The available Amazon
EC2 pricing models are claimed to provide organizations with the flexibility to choose from a
number of different instance types to meet specific computing needs. Each suite provides a
predictable amount of dedicated compute capacity, and is charged on a per instance-hour consumed
basis. According to AWS spokespersons, Amazon EC2 pricing models ensure that users pay only for
what they use. There is no minimum fee in the present Amazon EC2 pricing models.
When it comes to Amazon
EC2 pricing models, the instances are grouped into three families: Standard, High-Memory and
High-CPU. Amazon
EC2 pricing for each of these instances is as
follows:
i. Standard Instances: Have memory to CPU ratios suitable for most general purpose applications.
This Amazon EC2 pricing model ranges from $0.12 per hour to $ 0.96 per hour, for services running
on Windows infrastructure. For infrastructure running on Linux and UNIX, Amazon
EC2 pricing starts with $0.095 per hour to $0.76 per
hour.
ii. High-Memory instances: This Amazon EC2 pricing model offers larger memory sizes for high
throughput applications, including database and memory caching applications. This is priced at $
0.62 per hour to $2.88 per hour for Windows based infrastructure. For Linux/UNIX based instances in
this pricing model of Amazon EC2, prices range from $0.57 per hour to $2.68 per
hour.
iii. High-CPU instances: In this Amazon EC2 pricing model, proportionally more CPU resources are
consumed than memory (RAM), and as a a result it targets compute-intensive applications. This
Amazon EC2 suite has been priced at $0.29 per hour to $1.16 per hour for Windows based
infrastructure. For Linux or UNIX based infrastructure, this Amazon EC2 pricing model charges from
$0.19 per hour to $0.76 per hour.
When choosing Amazon EC2 pricing types, organizations should consider characteristics of their
application with regards to resource utilization. Accordingly, they should select the optimal
instance family and size.
