您是亚马逊云的用户的话,想必对EC2虚机、RDS托管数据库等云资源和费用不陌生,但云中数据流量多大、分布如何,特别是占了多少费用,很多人就不太了解了。事实上,大多用户的流量费用会占用云费用的10%以内,有的用户流量费甚至会超过虚机、数据库,成为最大的成本。这些流量费用怎么组成的,花的冤不冤,有没有节省空间,甚至有无可能又省钱又提速?本文就这些疑问为您提供一些思路。
上CDN,就上 CloudFront
省钱指数 ★ 风险指数 ★★★ 难度指数 ★★ 用户感知 ★★★★★
CDN(内容分发网络)可以把网站上的静态网页、图片、音视频,以及可缓存的动态内容,通过分布在世界各地的边缘节点分发给用户,实现数据秒回、界面秒开的效果,大大提升用户体验。
面向互联网用户的应用系统几乎100%使用了CDN加速。用户从最近的边缘节点获取内容,省去了跨省、跨国、跨洋的远征之旅。CDN的主要工作原理:靠第一个请求者触发缓存,实现"牺牲我一个、幸福全村人"的效果。
亚马逊的CDN服务叫 CloudFront(简称CF)。CF覆盖全球,与老牌专业CDN相比价格更便宜;对于源站在亚马逊云上的用户,CF还有配置简单、回源免费的优势。
如果您的系统面向广大互联网用户,赶紧考虑上CDN;如果系统在亚马逊云上,先配一下CF看看效果——按流量收费,不用不收费,随时启用、随时停止。
综合评价:省钱指数一颗星,风险指数三颗星,难度指数两颗星,用户感知五颗星。
流量又大又稳,就买亚马逊流量包
省钱指数 ★★★ 难度指数 ★ 风险指数 ★★★
CDN主要按流量计费,不同地区收费差别很大,南美、非洲等网络设施差的地区收费更高。亚马逊CF推出了折扣流量包 CloudFront Security Savings Bundle(2021年2月),提供"充70、得100"的优惠,最高可节省30%的CF费用,还附赠WAF积分。
但流量包必须定额连买一年,当月定额当月消费,过期作废不累积。例如:承诺每月付420美元,可得600美元积分;若当月CF费用不足600美元,剩余积分作废。
综合评价:省钱指数三颗星(能省30%),难度指数一颗星,风险指数三颗星(时间和机会风险)。
追求极致和完美,就买泰岳流量包
省钱指数 ★★★★★ 难度指数 ★ 风险指数 ★
泰岳流量包分为 CFRC-U 和 CFRC-A 两种:
- CFRC-A:类似亚马逊流量包,需承诺每月最低用量,但直接半价起算
- CFRC-U:不区分地区和数据包大小,不需要承诺用量和时间,按每G流量一口价,价格约腰斩
泰岳流量包的本质是分销亚马逊CDN流量,您用的是货真价实的CF流量,配置方式与直接在亚马逊中设置完全一样。优惠来自批零差价——泰岳作为分销商拿到了较低的批发价,并将优惠让利给客户;用量风险由泰岳汇集所有客户统一承担。
泰岳流量包还提供3天犹豫期,随时可以中止。CFRC-U 无需承诺,随时终止后可继续使用原价流量。
综合评价:省钱指数五颗星(5折起步),风险指数和难度指数均为一颗星。

If you're an AWS user, you're probably familiar with costs for EC2 instances and RDS databases — but many people don't pay close attention to data transfer costs. For most users, transfer fees account for less than 10% of their cloud bill, but for some, transfer costs can exceed compute and database costs combined. This article offers practical strategies to understand, reduce, and even eliminate unnecessary transfer costs.
Use a CDN — Go with CloudFront
Savings ★ Risk ★★★ Difficulty ★★ User Impact ★★★★★
A CDN (Content Delivery Network) distributes static web pages, images, audio/video, and cacheable dynamic content to users via edge nodes around the world, delivering near-instant load times and dramatically improving user experience.
Nearly 100% of internet-facing applications use CDN acceleration. Users retrieve content from the nearest edge node, bypassing long cross-region or cross-ocean routes. The core principle: the first request triggers caching at the edge, benefiting all subsequent users.
AWS's CDN service is CloudFront (CF). It has global coverage, competitive pricing compared to legacy CDN providers, and for workloads already on AWS, it offers simple configuration and free origin-fetch traffic.
If your system serves internet users, consider enabling a CDN. If you're on AWS, try CloudFront — it's pay-per-use with no upfront commitment, and you can enable or disable it at any time.
Summary: Savings ★, Risk ★★★, Difficulty ★★, User Impact ★★★★★
High and Stable Traffic? Buy an AWS Traffic Bundle
Savings ★★★ Difficulty ★ Risk ★★★
CDN is primarily billed by traffic volume, with significant regional price differences — South America and Africa are notably more expensive. AWS CloudFront introduced the CloudFront Security Savings Bundle (February 2021), offering up to 30% savings on CF costs plus WAF credits.
However, the bundle requires a fixed monthly commitment for one full year, with no rollover of unused credits. For example: commit to $420/month and receive $600 in credits; if your actual CF usage is under $600 that month, the remaining credits expire.
Summary: Savings ★★★ (up to 30%), Difficulty ★, Risk ★★★ (time and opportunity cost)
Want the Best Deal? Use UltraPower Traffic Bundles
Savings ★★★★★ Difficulty ★ Risk ★
UltraPower offers two CloudFront reseller traffic bundles:
- CFRC-A: Similar to the AWS bundle but starts at roughly half price, with a minimum monthly usage commitment
- CFRC-U: No regional distinction, no size tiers, no usage or time commitment — flat per-GB pricing at approximately half the standard rate
UltraPower traffic bundles are genuine AWS CloudFront traffic — the configuration is identical to using CF directly. The savings come from wholesale pricing: UltraPower purchases traffic at bulk rates as an authorized reseller and passes the savings on to customers. Usage risk is pooled across all customers.
A 3-day cancellation window is available. CFRC-U requires no commitment and can be cancelled at any time, after which you simply revert to standard CF pricing.
Summary: Savings ★★★★★ (50%+ off), Risk ★, Difficulty ★
