DMIT Cost Optimisation: From Plan Choice to Resources

Core principle of cost optimisation

DMIT cloud server cost optimisation isn't simply picking the cheapest plan — it's minimising spend while meeting business needs. This article covers optimisation at three levels: plan selection, resource utilisation and operations strategy.

Plan selection

Choose the right network series

Network series prices differ significantly. Choose based on actual needs — don't pay for features you don't use:

See Network Series Guide.

Use the refund window for testing

DMIT offers a 3-day full refund (≤30GB) window. Strategy:

• Buy a low-cost plan first to test if the route meets your needs
• If unsatisfied, refund within 3 days and try another plan
• Keep traffic under 30GB during testing

See Refund Policy Explained.

Pick the best value plan

Within the same series, value differs. Use two metrics:

• Per-GB traffic price: for high traffic, pick the lowest (usually higher Tier 1 tiers)
• Compute unit price: for compute, pick the lowest (usually 2 vCore + 4GB)

Lowest-cost picks

Based on the 2026-08-17 official snapshot:

Resource utilisation

Monitor resource usage

Many users buy large plans but use them poorly. Monitor before deciding to downgrade:

# Monitor for a week
sar -u -f /var/log/sysstat/sa$(date +%d)  # CPU
sar -r -f /var/log/sysstat/sa$(date +%d)  # Memory
sar -d -f /var/log/sysstat/sa$(date +%d)  # Disk

If CPU peak stays under 30% and memory under 50% for a week, consider downgrading.

Use swap wisely

Memory shortage doesn't always require an upgrade — swap can handle occasional peaks:

fallocate -l 2G /swapfile
chmod 600 /swapfile
mkswap /swapfile
swapon /swapfile
echo '/swapfile none swap sw 0 0' >> /etc/fstab
sysctl vm.swappiness=10

Note: frequent swap hurts performance. If swap use consistently exceeds 1GB, upgrade.

Consolidate services

Multiple light services can share one instance to reduce count:

• Web + database + cache on one machine (if resources allow)
• Use Docker containers to isolate services
• Use Nginx reverse proxy to route by domain to different apps

Operations strategy

Use DMIT snapshots

DMIT snapshots are free and useful for:

• Saving configured environments to avoid rework
• Quickly cloning new instances
• Rollback points to avoid costly recovery from mistakes

Monthly billing over yearly

DMIT plans support monthly billing. Benefits:

• Flexibility: switch plans as needs change
• Lower risk: 3-day full refund window applies each cycle (first cycle only)
• Avoid lock-in: migrate if line quality drops

Traffic management

Exceeding traffic quota may incur extra fees or throttling. Manage traffic:

vnstat -m   # monthly stats
vnstat -d   # daily stats

# Traffic alert cron job
#!/bin/bash
USAGE=$(vnstat --oneline | awk -F';' '{print $9}')
LIMIT=80
if [ "$USAGE" -gt "$LIMIT" ]; then
    echo "Traffic alert: $USAGE GB used" | mail -s "Traffic Alert" you@example.com
fi

If you often exceed traffic, Tier 1 (larger allowances) is more cost-effective.

Cost optimisation decision tree

1. Low resource utilisation?
   ├─ Yes → downgrade to a cheaper plan
   └─ No → continue

2. Traffic often exceeded?
   ├─ Yes → switch to Tier 1 (more traffic)
   └─ No → continue

3. Need China routing optimisation?
   ├─ No → Tier 1 (cheapest)
   ├─ Premium quality → Premium
   └─ Balanced → Eyeball (HKG)

4. Multiple light services?
   ├─ Yes → consolidate to one instance
   └─ No → keep as is

5. Occasional memory spikes?
   ├─ Yes → add swap, don't rush to upgrade
   └─ No → monitor and decide

Common misconceptions

• "Cheapest is most economical" — if the route doesn't meet needs, frequent refunds and migrations waste time.
• "Bigger is better" — low utilisation is the biggest waste; monitor first.
• "Yearly is always cheaper" — DMIT monthly billing has refund protection; flexibility matters more.
• "Eyeball is worst because it's priciest" — Eyeball offers unique China-optimised routing; price reflects positioning.
