Control Your Amazon AWS Cloud Data Transfer Costs

The traffic of a typical web application directly linked to the amount of concurrent users that use the system. The variations in daily traffic volumes generated by a typical web application match our daily life schedule. Data Traffic transfer, running the application on Amazon cloud, can mean substantial costs. These cloud costs can even amount to more than half the overall charges for all instances utilized for the same amount of time.

The cost of traffic on Amazon AWS stems from two main factors:

1 - Outbound data transfer, between regions as well as out of the Amazon cloud.

2 - ELB data transfer fees across availability zones (AZ).

How I Learned not to fear Amazon Cloud Lock-in

Following Max B. post on KnowYourCloud and based on questions received at AWS Usergroup meetups I realized that there is a reasonable (but sometimes exaggerated) concern about the level of lock-in to AWS. In this article we will try to put the problem in the right perspective and explain the practical lock-in considerations for the various services of Amazon’s cloud. 

What is vendor lock-in? Vendor lock-in is the situation where a business becomes overly dependent on a specific service or product provider.

Should I worry?

EBS Volumes have No Backup

An EBS Snapshot is a copy of an EBS volume at a particular point in time. A snapshot can be taken of a volume, regardless of whether or not the volume is attached to a running instance. A snapshot comprises data blocks that are incrementally saved to Simple Storage Service (S3), meaning that only the blocks on the device that have changed since your last snapshot are saved. When saved to S3, the snapshot is assigned a timestamp and unique AWS ID. 

Amazon AWS storage basics: Stop the sprawl before it begins!

There is a common perception that cloud storage should not really worry you because it is very cheap and available at any time. But is that really true? I often hear AWS consumers say that AWS storage means S3 (Simple Storage Service) – this is true but it is not the whole truth. There are actually 4 different AWS cloud storage models. We’ll get back to those but first let’s focus on the importance of understanding your AWS S3 footprint.
