    Billing Modes

    TencentDB for MongoDB supports monthly subscription and pay-as-you-go billing modes.

    Monthly subscription

    Monthly subscription is a prepaid billing mode. It is applicable to long-term businesses with stable peak traffic, and is cheaper than the pay-as-you-go mode. To purchase a monthly subscription MongoDB instance, you need to pay for one or multiple months or even years in advance as needed.

    Pay-as-you-go

    Pay-as-you-go is a postpaid billing mode. We recommend you choose the pay-as-you-go billing mode if your business may fluctuate greatly and unpredictably or your resource usage tends to be temporary or abrupt. When you purchase a TencentDB for MongoDB instance, the hardware fees of one hour will be frozen in your Tencent Cloud account and charged on the hour (Beijing time), with the billable usage duration accurate down to the second. In this mode, you only need to pay for the actual usage of TencentDB for MongoDB with no upfront payment required.
    The tiered pricing model is based on usage duration.

    • 0 days < duration ≤ 4 days: tier 1 pay-as-you-go price applies.
    • 4 days < duration ≤ 15 days: tier 2 pay-as-you-go price applies.
    • Duration > 15 days: tier 3 pay-as-you-go price applies.

    Compute

    Computing resources include CPU resources and memory resources. Instance parameters such as the maximum QPS and number of access connections are subject to the selected computing resource specification. For the prices, please see MongoDB Pricing.

    High IO 1 core 2 GB 3,000 1,500
    High IO 2 cores 4 GB 5,000 2,000
    High IO 2 cores 6 GB 5,000 2,500
    High IO 4 cores 8 GB 9,000 3,500
    High IO 6 cores 16 GB 20,000 6,000
    High IO 10 cores 24 GB 25,000 8,000
    High IO 12 cores 32 GB 27,000 9,500
    High IO 24 cores 64 GB 33,000 16,000

    Ten-Gigabit High IO 6 cores 16 GB 20,000 6,000
    Ten-Gigabit High IO 12 cores 32 GB 27,000 9,500
    Ten-Gigabit High IO 24 cores 64 GB 33,000 16,000
    Ten-Gigabit High IO 24 cores 128 GB 36,000 18,000
    Ten-Gigabit High IO 32 cores 240 GB 39,000 18,000
    Ten-Gigabit High IO 48 cores 512 GB 42,000 18,000

    Note:

    • The above numbers of connections have taken effect since August 10, 2020.
    • For a replica set, the maximum number of connections for an instance is as indicated in the table above; for a sharded cluster, the maximum number of connections is the number of shards * specification of single shard or 18,000, whichever is smaller.
      For example, if a sharded cluster instance has 3 shards, each with 64 GB memory, then as 16,000 * 3 = 48,000 > 18,000, the maximum number of connections for this cluster will be 18,000.
