Choosing a cloud server for your DTC site: AWS vs. Alibaba Cloud vs. Tencent Cloud specs, pricing, and migration

Choosing a cloud server for your DTC site: AWS vs. Alibaba Cloud vs. Tencent Cloud specs, pricing, and migration

1. The first question: what time zone are your customers in?

A lot of people compare prices first when picking a server. That’s the wrong order. Your DTC site is for overseas customers, and the server’s physical location determines how long they wait the first time they open the page. For an East Coast US customer hitting an Alibaba Cloud Hong Kong region, the TCP handshake plus time to first byte usually takes over 300 milliseconds. Put the same page on an AWS Virginia region and it takes just 80 milliseconds. B2B buyers wait an average of only 3 seconds before they close the page.

A simple rule: put the server in the availability zone closest to wherever most of your customers are. If your users are spread across Europe and the US, use a CDN for global acceleration instead of parking the server somewhere in the middle. For a full breakdown of market priorities, see Market Priority for Going Global, and for how to pair it with a CDN, see CDN global acceleration.

2. How to choose specs: is 2 vCPU, 4 GB enough?

For the first 6 months after launch, traffic to your DTC site is low 90% of the time. A 2 vCPU, 4 GB VPS can run Nginx + PHP-FPM + MySQL + Redis and handle up to 10,000 daily visits without strain. Past 30,000 daily visits, upgrade to 4 vCPU, 8 GB. Don’t buy 8 vCPU, 16 GB right away. You’ll pay 600 RMB more a month for utilization that stays under 20% for a long time.

Storage and bandwidth matter more than CPU. Use SSD cloud disks, not standard HDDs — MySQL random reads on HDD will make your pages twice as slow. On bandwidth, pay-as-you-go is cheaper than a fixed plan for low traffic: under 100GB a month, pay-as-you-go costs about ¥30, while a fixed 5Mbps plan starts at ¥100. Watch your traffic curve before deciding.

3. How to choose among the three providers: price, support, ecosystem

The three providers differ not in technology but in service. Alibaba Cloud and Tencent Cloud are friendly to Chinese teams — Chinese-language docs, fast ticket responses, and local payment methods — making them a good fit for budget-conscious small teams that solve technical problems by searching. AWS offers the widest overseas node coverage, the most peering interconnects, and the richest third-party ecosystem, but its Chinese-language support is weak and its billing is complex, so it suits teams with dedicated ops staff or businesses already operating overseas.

Here’s a decision tree you can act on: if 90% of your customers are in Southeast Asia and no one on your team reads English, choose Alibaba Cloud Singapore. If your customers span Europe and the US and your monthly budget is over ¥10,000, choose AWS. If you just want to test overseas markets cheaply, start with a 2 vCPU / 4GB instance from Vultr or DigitalOcean at ¥50 a month, and migrate once it works. For the CDN and object storage setup you’ll migrate to, see CDN global acceleration.

4. Migrating from a Chinese cloud to an overseas cloud without losing SEO

Switching cloud providers doesn’t mean switching domains, but it affects both SEO and customer access. Migration has four steps: first spin up a machine with the same specs at the new provider and sync your code, database, and static assets over completely. Then point DNS to the new IP and set TTL to 600 seconds. Watch for two weeks — if Google indexing and rankings look normal, release the old machine. Throughout the process, don’t change your domain, don’t change your URLs, and you won’t need a single 301.

What actually hurts SEO is downtime during migration and DNS switchover jitter. One rule of thumb: pick a low-traffic window for the migration (early morning China time, which is lunch break in Europe and the US), run shadow traffic on the new machine for 72 hours to validate, then switch DNS. For the full 301 strategy when changing domains, see Site rebuilds and domain changes.

5. Cost control: what to do when the bill runs over

Three things cause most cloud bill overruns: outbound public traffic, snapshots, and disks and IPs you never released. A direct-to-consumer site usually pushes 100 to 500GB a month, which costs 30 to 400 yuan on pay-as-you-go traffic. But if you forget to set up a CDN, every image is served from the origin, and one month can hit 2TB and multiply your bill by 10.

Three ways to save: route all static assets through the CDN so the origin only serves HTML; turn off automatic snapshots and take one manual backup a week instead; and release the public IP and system disk when you take an instance offline. Here’s a rule you can actually follow: check last month’s bill at the start of each month. Over 500GB of public traffic, turn on a CDN. Over 1TB, check whether you’re being scraped. For the full backup strategy, see Backup and recovery drills for your site.

Final thoughts

Choosing a cloud server for your independent store isn’t about picking “the best provider” — it’s about where your customers are, what your budget is, and how much your team can maintain. Start with 2 cores and 4 GB, SSD cloud disks, pay-as-you-go billing, and a CDN for static assets. Get these four right and you can keep monthly costs under 200 yuan, with enough performance and stability for a B2B site.

Three steps to launch: first, use latency testing tools (such as Pingdom or website speed tests) to pick 3 candidate nodes and measure time to first byte in your target customer cities; second, run on-demand instances for 2 weeks with shadow traffic; third, once everything checks out, migrate your live traffic. The whole process takes no more than 3 weeks. For monitoring and alerts once your server is stable, see Site monitoring and alerts.

One line worth remembering: a cloud server isn’t better the more it costs — it’s better the closer it is to your customers. The latency you save by picking the right node is worth ten times the monthly fee you save.
