Kepiye cara AWS ngetung rega?

Question

Accepted Answer

AWS nggunakake model harga **pay-as-you-go** — sampeyan mung mbayar kanggo sumber daya sing digunakake, tanpa komitmen awal kanggo akeh layanan. Ngerti model harga, faktor biaya umum, lan cara ngontrol biaya iku pengetahuan praktis penting (tagihan cloud bisa ngejutake sampeyan).

## Model pay-as-you-go

```text
Most AWS services charge based on USAGE, with no upfront cost:
  → COMPUTE — per second/hour an instance runs (EC2), or per request/duration (Lambda)
  → STORAGE — per GB stored per month (S3, EBS)
  → DATA TRANSFER — often charged for data OUT to the internet (a common surprise!)
  → REQUESTS/operations — per API call, per request (S3, DynamoDB, Lambda)
→ Pay for what you use; scale cost with usage.
```

## Free Tier (kanggo sinau)

```text
AWS FREE TIER lets you try services free (great for learning):
  → ALWAYS FREE — some services have a perpetual free allowance (e.g. Lambda requests)
  → 12 MONTHS FREE — some free for a year for new accounts (e.g. 750 hrs/mo t2.micro EC2)
  → TRIALS — short-term free trials of some services
⚠️ Exceeding free-tier limits incurs charges — monitor usage!
```

## Ngontrol biaya (penting!)

```text
⚠️ Cloud bills can SURPRISE you (forgotten resources, data transfer, misconfigurations):
✓ BILLING ALERTS / Budgets — get alerted when spending exceeds a threshold (set these up!)
✓ Cost Explorer — analyze and visualize spending
✓ Stop/terminate UNUSED resources (a forgotten running instance costs money 24/7)
✓ RIGHT-SIZE — don't over-provision; use the appropriate instance/service size
✓ Use RESERVED/Savings Plans for steady workloads; Spot for fault-tolerant ones
✓ Watch DATA TRANSFER costs; use lifecycle policies for storage tiering
```

## Mengapa iki penting

Ngerti harga AWS iku pengetahuan praktis penting amarga biaya cloud iku perhatian nyata lan signifikan — tagihan bisa ngejutake sampeyan, lan ngerti model lan kontrol biaya iku perlu kanggo nggunakake AWS kanthi tanggung jawab lan ngindhari biaya sing ora dikarepake.

Model **pay-as-you-go** (mbayar kanggo panggunaan asli compute, storage, data transfer, lan requests, tanpa komitmen awal) iku fondasi — fleksibel lan scalable, nanging tegese biaya terus nambah seiring panggunaan.

Ngerti **faktor biaya umum** (wektu compute, storage per GB, **data transfer out** sing asring dadi kejutan, lan per-request charges) membantu ngantisipasi lan ngerti tagihan.

Free Tier iku berharga kanggo sinau (ngowahi sampeyan nyoba layanan gratis ing batas), nanging ngerti manawa melampaui batas nggawa biaya iku penting.

Paling kritis, ngerti **kontrol biaya** iku pengetahuan praktis penting: tagihan cloud nyata-nyata **ngejutake wong** (sumber daya sing lagi jalan terlupakan, data transfer ora dikarepake, misconfiguration bisa ngecirak biaya nyata), dadi ngerti **nyetel billing alerts/budgets** (entuk pemberitahuan sadurunge biaya madhani), **mungkasi sumber daya sing ora digunakake** (instance terlupakan nggawa biaya 24/7 — kesalahan umum lan nyata), **right-size** sumber daya (ora over-provisioning), gunakake opsi harga sing cost-effective (reserved/savings plans, spot), lan monitor pengeluaran (Cost Explorer) iku perlu kanggo ngindhari tagihan sing boros utawa ngejutake.

Kesadaran biaya iki iku skill dunia nyata sing genuinely penting, amarga pengeluaran cloud sing ora dikontrol iku masalah umum.

Samuwon AWS biaya iku perhatian nyata (kanthi potensi tagihan ngejutake) lan ngerti model harga lan luwih penting kontrol biaya iku perlu kanggo nggunakake AWS kanthi tanggung jawab, ngerti harga AWS — model pay-as-you-go, faktor biaya, free tier, lan luwih kritis praktik kontrol biaya kaya billing alerts lan ngelola sumber daya terlupakan — iku pengetahuan berharga lan praktis-penting kanggo sapa wae sing nggunakake AWS, nulungi ngindhari kesalahan mahal lan kejutan tagihan sing nyedhot akeh cloud users.
