This document explains Pub/Sub Lite pricing details.
Pub/Sub Lite is free for a limited time during the beta period. This pricing information is for reference.
Pub/Sub Lite pricing is based on the following:
- The throughput capacity that you provision for partitions
- The amount of storage that you provision for partitions
Throughput capacity is priced per partition per hour. Pub/Sub Lite charges for the maximum amount of publishing and subscribing throughput that you provision in the hour.
Throughput capacity is provisioned in MiB per sec. A partition can have 4 to 16 MiB per sec of publishing throughput capacity and 4 to 32 MiB per sec of subscribing throughput capacity.
A partition must have at least 30 GiB of storage. Each of the partitions in a Lite topic has the same amount of storage.
Pub/Sub Lite charges for the maximum amount of storage that you provision in a month.
The pricing table shows what charges apply when using Pub/Sub Lite.
For an example scenario with usage and charges, see Pricing example.
To determine how much capacity to provision to a Pub/Sub Lite system, account for the throughput and storage that you need on average and any spare capacity for peak traffic.
If you use 10 MiB per sec of publishing throughput and 20 MiB per sec of subscribing throughput on average, provision 20 MiB per sec of publishing capacity and 40 MiB per sec of subscribing capacity, at a cost $180 per month in North America.
The following table shows the cost of this usage pattern and how scaling the throughput capacity changes the cost:
|Data published/s||Data received/s||Data published/mo||Publishing capacity/s||Subscribing capacity/s||Cost|
|1 MiB||1 MiB||2.5 TiB||4 MiB||4 MiB||$27|
|1 MiB||2 MiB||2.5 TiB||4 MiB||4 MiB||$27|
|10 MiB||10 MiB||25 TiB||20 MiB||20 MiB||$135|
|10 MiB||20 MiB||25 TiB||20 MiB||40 MiB||$180|
|100 MiB||100 MiB||247 TiB||200 MiB||200 MiB||$1,350|
|100 MiB||200 MiB||247 TiB||200 MiB||400 MiB||$1,800|
To estimate the storage and the cost of storage per partition, determine how long to store messages and how much spare storage you need. For example, to publish 4 MiB of messages per sec and retain messages for one day, provision 337.5 GiB of storage. To save half of the storage for traffic increases, provision each partition at least 675 GiB.
The following table shows the cost of storage in North America:
|Data published/s||Data published/mo||Maximum storage/mo||Cost/partition|
|1 MiB||2.5 TiB||84 GiB||$3|
|10 MiB||25 TiB||844 GiB||$34|
|100 MiB||247 TiB||8438 GiB||$338|
The following table compares the monthly cost of Pub/Sub Lite and Pub/Sub systems that store messages for one day:
|Data published/s||Data published/mo||Data received/mo||Storage/mo||Total Pub/Sub Lite cost||Total Pub/Sub cost|
|1 MiB||2.5 TiB||2.5 TiB||84 GiB||$27||$200|
|1 MiB||2.5 TiB||5 TiB||84 GiB||$27||$300|
|10 MiB||25 TiB||25 TiB||844 GiB||$169||$2,000|
|10 MiB||25 TiB||50 TiB||844 GiB||$214||$3,000|
|100 MiB||247 TiB||247 TiB||8438 GiB||$1,688||$19,760|
|100 MiB||247 TiB||494 TiB||8438 GiB||$2,138||$29,640|
