小米國際用戶資料將從中國北京遷移至美國與新加坡伺服器。小米全球副總裁 Hugo Barra 在他的 Google+ 宣布，包括香港、印度、印尼、馬來西亞、菲律賓、新加坡與台灣用戶資料，未來將從中國北京轉移至美國與新加坡伺服器，這有助於提昇速度，並保護用戶的隱私。
這項計劃共分為三個階段，並早在 2014 年初已經開始執行。
第一階段是電子商務整合，主要是將香港、印度、印尼、馬來西亞、菲律賓、新加坡與台灣國際用戶資料轉一致美國與新加坡 Amazon AWS 伺服器，透過 Akamai 全球 CDN 架構加快加載速度，整體速度會有 30% 至 200% 不等的提升，預計 2014 年 10 月底完成。
第二階段為 MIUI 服務轉移至美國與新加坡 Amazon AWS 伺服器，內容包括小米帳號、小米通訊及小米雲端，預計 2014 年底完成搬遷，而小米帳號部份約 10 月底前就會完工，整體速度會大為提昇。
第三階段會在 2015 年完成，針對像是巴西、印度等地區，與當地伺服器業者合作，帶來更優質的服務。
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!
