正當蘋果把部份用家資料由美國移到中國，方便部份中國用家的時候，早前被人批評的小米，其虎哥Hugo Barra剛在Facebook宣佈，把國際用家的資料從北京的伺服器，移到美國加洲和新加坡。在提到國際用家時，當中還包括香港。
Hugo Barra提到搬遷用家資料的計劃分三個階段，並在2014年頭已經開始，他們的目的是希望全球的小米Fans可以用得更開心。此外，他們亦希望小米手機會因此而表現更好，減低延遲時間以及錯誤比率。另外，這次計劃也可以幫助他們確保更高的私隱標準。
第一階段是針對E-Commerce整合，而國際用家的資料亦由北京移至新加坡和美國加洲的Amazon AWS數據伺服器。他們亦同時使用Akamai的全球CDN架構加快載入速度，有關整合將於10月尾完成，香港、印度、印尼、馬來西亞、菲律賓、新加坡和台灣的用家將陸續感受到速度上的分別，現在有部份用家亦最少感受到30%的速度提升。
第二階段則是針對MIUI的小米服務，屆時將會把用家的資料由北京移至美國Oregon和新加坡的伺服器，預計將於2014年尾完成，當中包括小米戶口、雲端訊息和小米雲端服務等。而第三階段則針對印度和巴西，因為有關市場發展快，他們將嘗試與當地的伺服器合作提供更佳的服務。

>> We’re moving your data! << User experience is hugely important to us. As a global Internet company, we really care about speed and we're also fully committed to storing our users' data securely at all times. In early 2014, we kicked off a massive internal effort to expand our server infrastructure globally in order to better serve Mi fans everywhere. Our primary goal in moving to a multi-site server architecture was to improve the performance of our services for Mi fans around the world, cut down latency and reduce failure rates. At the same time, it also better equips us to maintain high privacy standards and comply with local data protection regulations. This is a very high priority for Xiaomi as we expand into new markets over the next few years. This server and data migration process is taking place in three phases. >> PHASE 1: E-commerce migration
Earlier this year, our e-commerce engineering teams started migrating our global e-commerce platforms and user data for all international users from our Beijing data centers to Amazon AWS data centers in California (USA) and Singapore. We also began using Akamai’s global CDN infrastructure to speed up static page loads.
This migration process will be completed by the end of October and will benefit users in all of our international markets — Hong Kong, India, Indonesia, Malaysia, Philippines, Singapore, and Taiwan. Users are already experiencing website speed boosts of at least 30% in markets such as Singapore, Hong Kong, Taiwan and as much as 200% in India.
>> PHASE 2: MIUI services migration
We have also recently started migrating our MIUI services and corresponding data for all international users from our Beijing data centers to Amazon AWS data centers in Oregon (USA) and Singapore. This migration includes Mi Account, Cloud Messaging and Mi Cloud services. We are expecting to complete this migration by the end of 2014, with some parts being completed even sooner (e.g. Mi Account servers by the end of October).
With this migration, we are expecting to cut network request latency for users in India by up to 350ms, and users in Malaysia to experience 2-3x faster Mi Cloud photosync.
>> PHASE 3: Going local
In 2015, we are planning to take on a new challenge to further improve the performance of our services for users in large and fast-growing markets such as India and Brazil.
In these markets, where Amazon AWS services aren’t yet available, we will be working with local data center providers to set up our service infrastructure. Once that has been completed, users in these markets will be much closer to their data and enjoy even faster speeds by connecting to local servers.
We will continue to keep everyone posted!
