S3 and the Amazon Values
Almost every company has a mission statement of some kind. At Amazon.com, we are guided by our Leadership Principles. We use these principles as part of the interviewing process, and revisit them during our annual reviews.  I thought back to the launch of S3 and the long string of additional features that we have added to it since then, and tried to match them up to some of the leadership principles.

nature of the phrases.

Attention-Getting Words and
Phrases For Hot-Selling Copy
The right words help you express the function of your product or service
with flair. They add color and drama to your presentation to make it more
interesting. Try to use words that evoke emotions and vivid mental pictures. Let
your prospect enjoy a little fantasizing about what his or her life could be like.
Employ selected words solely for their shock value. Stop readers in their
tracks. You demand attention by using words and phrases not normally associated
with your type of business, product, service, or your chosen communications
vehicle.

T2: T2 instances are Burstable Performance Instances that provide a baseline level of CPU performance with the ability to burst above the baseline. The baseline performance and ability to burst are governed by CPU Credits. Each T2 instance receives CPU Credits continuously at a set rate depending on the instance size. T2 instances accrue CPU Credits when they are idle, and use CPU credits when they are active. T2 instances are a good choice for workloads that don’t use the full CPU often or consistently, but occasionally need to burst (e.g. web servers, developer environments and small databases).

Burstable Performance Instances: Provide a baseline level of CPU performance with the ability to burst above the baseline.
