Overview
Tencent Cloud Distributed Cache offers two billing modes: yearly/monthly subscription and pay-as-you-go. Users can select the appropriate billing mode based on business needs, cost budgets, and resource usage patterns. This document details the features, rules, and selection recommendations for both billing modes.
Billing Modes
Comparison Item
Yearly/Monthly Subscription
Pay-as-You-Go
Billing method
Prepaid: Pay the full fee for the selected duration (such as month and year) in one go.
Subscription period: Monthly/Yearly purchase. The minimum subscription period is 1 month, and the maximum is 5 years.
Product pricing: Priced on a monthly basis. The longer the subscription period, the more pricing discounts you get. For specific pricing, see Pricing Center.
Postpaid: Billed hourly. Pay after usage.
Settlement cycle: Upon activation, one hour's fee will be frozen in your cloud account. At the top of every hour (UTC+8), the fee for the previous hour will be settled automatically.
Product pricing: Tiered pricing based on usage duration. The hourly unit price decreases progressively with each tier. For specific pricing, see Pricing Center.
Tier 1: 0 days < Duration ≤ 4 days, Hourly price = Monthly price/30/24 x 2.
Tier 2: 4 days < Duration ≤ 15 days, Hourly price = Monthly price/30/24 x 1.5.
Tier 3: Duration > 15 days, Hourly price = Monthly price/30/24.
Note:
After instance scale-out, scale-in, or isolation, the pricing calculation restarts from Tier 1.
The price of pay-as-you-go tier 3 is basically the same as that of yearly/monthly subscription.
Key rules
Renewal: Instances can be renewed manually or automatically upon expiration. For specific renewal operations, see Renewal.
Return: Instances can be unsubscribed at any time, with remaining fees settled according to applicable rules. For specific refund policies, see Refund.
Overdue Payments: If an instance expires without renewal and remains in arrears beyond the grace period and retention period, the instance will be released. For details on how to deal with overdue payments, see Overdue Payments.
﻿
Termination: Instances can be terminated at any time, with fees settled per second based on usage.
Overdue Payments: If the account balance is insufficient, the instance will be released after overdue payments exceed the grace period and retention period.
Core strengths
Lower unit prices, and more favorable long-term usage costs.
Highly flexible, with on-demand resource purchase and release to adapt to business fluctuations.
Application scenarios
Production environments or core business that is stable and operates over the long term.
Business with significant traffic fluctuation and temporary needs (such as development and testing and promotional campaigns).
Billable Items
Billing basis: Billing is based on the instance's memory capacity (such as 1 GB, 4 GB, 16 GB, 64 GB, and so on).
Cost coverage: The cost covers the consolidated costs of the following core resources.
Computing resources: CPU resources that support the operation of the Tencent Cloud Distributed Cache service.
Memory resources: Data storage space.
Network and maintenance: Private network access for instances, and underlying platform maintenance.
Pricing policy: Linear pricing, where cost is proportional to memory capacity. The larger the capacity, the higher the cost.
Regional variations: Infrastructure costs differ across regions, and pricing varies accordingly.
Architectural differences: Pricing varies across product series based on performance, features, and complexity.
Billing Formula
Standard Architecture
Cost = Per-node memory x Per-node pricing x Number of nodes
Note:
The standard architecture supports primary-secondary replication mode, such as a 1-master-1-replica architecture that includes 2 nodes. During billing, the total memory capacity of all nodes must be accounted for.
Assume that you select the standard architecture and 1-master-1-replica mode, with per-node memory of 8 GB and per-node pricing of 5.30 USD/GB/month: Yearly/monthly subscription cost calculation: 8 GB x 5.30 USD/GB/month x 2 nodes = 84.8 USD/month.
Cluster Architecture
Cost = Per-shard memory x Per-shard pricing x Number of nodes x Number of shards
Note:
The cluster architecture is composed of multiple shards, with each shard supporting primary-secondary replication. During billing, the total memory capacity of all shards and their nodes must be accounted for.
Assume that you select the cluster architecture, 3 shards, with each shard in 1-master-1-replica mode, per-shard memory of 8 GB, per-node pricing of 5.86 USD/GB/month:
Yearly/monthly subscription cost calculation: 8 GB x 5.86 USD/GB/month x 2 nodes x 3 shards = 281.28 USD/month.
Cost Estimation
To estimate costs, first determine the product series and billing mode based on your business scenarios., Then, select the required memory specifications, and query the detailed pricing details for the target region.
