One of the main reasons why most of the companies move their IT services to cloud is
to save
money. With AWS it is common knowledge that EC2 reserved instance is at a discounted rate. RDS
is another service that can be reserved.
However not many know that additional services from AWS can be reserved on upfront
commitments.
These are the 5 AWS services that can be reserved:-

REDSHIFT:
Redshift is a fully managed data warehouse solution. In order to run this service four
different instances are available, two of which are optimised for compute power & other
two for storage. You can reserve all partial or no upfront instances for either 1 or 3 years
at a discounted rate of upto 40% to 70% respectively.
-
ELASTICACHE:
This AWS provides in-memory cache services to retrieve data from disk based databases. It
runs using 1 or 2 popular open source in-memory caching mechanised engines. Redis elasticache
has 3 types of current generation instances, two of which are general purpose & one is
RAM optimised. To save on cost with instance you can reserve these elasticache instances
based on heavy utilization reservation. The discount is based on 1 time reservation fee that
gives discounted hourly rate for using reserved instance.
-
Elastic MapReduce:
This service processes large set of data using MapReduce workloads. The pricing for EMR is
based on hourly basis for the MapReduce service, on top of an hourly rate for underlying EC2
instances that are used. While the MapReduce rate is fixed, you can lower the cost by buying
EC2 reservations for instances that would be used by EMR.
-
CLOUDFRONT:
AWS Cloudfront is a popular content delivery network (CDN) service. It brings content closer
to users by distributing from multiple global edge locations. The pricing of this service
mostly comes from data transfer services to and from edge locations and from HTTP requests.
To receive a discount on cloudfront you need to make a 12 month commitment & have a
minimum monthly usage level that starts at 10TB per month. The higher the capacity requested,
the larger the discount. However the pricing can only be found by contacting Amazon
directly.
-
DynamoDB:
DynamoDB is a noSQL fast database as a service that supports document & key value store
models. When you create or update your DynamoDB table, you specify how much capacity you wish
to reserve for reads & writes. Amazon DynamoDB will reserve the necessary machine
resources to meet your throughout needs with consistent, low latency performance. You can
commit to 100 reads and/or write capacity units per month on 1 year or 3 year term. The price
includes an upfront fee & an ongoing hourly rate.
