Pricing for Redis in Azure

With our consumption-based pricing you only pay for what you actually use. The amount you are charged is based on your memory, CPU and disk usage, measured every second of every day. Below is our pricing followed by cost saving examples (based on US East (Virginia)).

Memory $0.00002 per GB-s
CPU $0.00001 per CPU-s
Data Recovery $0.08000 per GB written
Backups NO CHARGE
Bandwidth NO CHARGE

Site uses an average of 1.5GB during peak usage with approximately 500 active users, creating approx. 50 requests/sec with an average payload of 10KB. Peak usually lasts 4 hours/day, with non-peak average usage of 200MB and 15 requests/sec.

MEMORY CHARGES:

1.5 GB X 3600 seconds/hr X 4 hours X 30 days = 648,000 GB-s

0.2 GB X 3600 seconds/hr X 20 hours X 30 days = 432,000 GB-s

TOTAL MEMORY: 1,080,000 GB-s X $0.00002 = $21.60

CPU CHARGES:

0.000167s X 3600 seconds/hr X 4 hours X 30 days = 72 CPU-s

0.000022s X 3600 seconds/hr X 20 hours X 30 days = 48 CPU-s

TOTAL CPU: 120 X $0.00001 = $0.0012

TOTAL ZIPPYDB™ COST: $21.60

Note that Redis Labs base pricing does not include a replica and users must choose a tier that is 2X required memory or more for HA

A large WordPress site uses Redis to store its page cache, using approximately 4GB of memory. The pages are largely static, with approx. 100MB of updates per day. Peak loads average 8 hours/day and it sees an average of 20 requests/sec with an average payload of 60KB. Non-peak usage averages 3 requests/sec. Data Redundancy is used to ensure cache doesn’t have to be rebuilt from scratch in case of failure or application error.

MEMORY CHARGES:

4 GB X 3600 seconds/hr X 24 hours X 30 days = 10,368,000 GB-s

TOTAL MEMORY: 10,368,000 GB-s X $0.0002 Per GB-s = $207.36

CPU CHARGES:

0.002s X 3600 seconds/hr X 8 hours X 30 days = 1728 CPU-s

0.0003s X 3600 seconds/hr X 16 hours X 30 days = 518 CPU-s

TOTAL CPU: 2246 CPU-s X $0.00001 = $0.0225

DATA RECOVERY CHARGES:

4GB + (0.1GB/Day X 30 Days) = ~7GB Writes

TOTAL DATA RECOVERY: 7 GB Writes X $0.08 = $0.56

Note that Redis Labs base pricing does not include a replica and users must choose a tier that is at least 2X required memory for HA

A customer processes a 300-500MB/day set of files against a 30GB dataset. In SQL Server the process would take 7 hours. Using Redis + LUA they are able to process the same changes in under 10 minutes. The dataset is available 24×7 for non-ETL operations.

MEMORY CHARGES

35 GB X 10 minutes X 60 seconds/minute X 30 days = 630,000 GB-s

30 GB X 3600 seconds/hr X 23.8 hours X 30 days = 77,220,000 GB-s

TOTAL MEMORY: 77,850,000 GB-s X $0.0002 Per GB-s = $1,557.00

CPU CHARGES:

1s X 10 minutes X 60 seconds/minute X 30 days = 18,000 CPU-s

0.0001s X 3600 seconds/hr X 23.8 hours X 30 days = 257 CPU-s

TOTAL CPU: 18,257 CPU-s X $0.00001 = $0.1826

ACCOUNT TIERS

ZippyDB™ utilizes account tiers to determine maximum instance and account sizing to ensure adequate capacity for customers. For customers with larger instance and/or account needs we have Reserved accounts that allow for larger instance and account size limits, while also providing credits based on prepayment amount.

For Reserved accounts there will be a credit applied to the account based on the prepaid amount. However, there will be no refunds for unused portions of the prepaid and/or the credit amount. Once the prepaid and credit amount are used within the term period, any remaining service usage will be based on current rates. Contact us for full terms and details.

To support their applications, Widget Co averages using 5 instances that in aggregate use an average of 50GB per month, with a peak instance usage of 20GB. To account for unexpected spikes, Widget Co sets up a ZippyDB™ Reserved account with a 30GB instance limit and 80GB account limit. Widget Co makes a reserved prepayment each month of $1,100 and gets a bonus credit of $275, for a starting balance of $1,375. Based on normal usage, their standard bill with no prepay would be approximately $2,800 per month less $1,375 starting balance for a remaining bill of $1,425.

If Widget Co decided to switch to a 3-year prepayment plan, they would pay $39,600 and receive a credit of $21,780, for a total balance of $61,380.

COMMON PRICING QUESTIONS

How does ZippyDB™ consumption-based pricing work?

Your instance CPU, Memory and Disk usage is measured every second. At the end of the month we sum up your total usage of CPU, Memory, Disk and Bandwidth and bill you for the total usage based on current pricing.

Do you offer reserved pricing?

Yes, please see our account tiers for pricing discounts.

Can pricing exceed Azure or Redis Labs pricing?

Under the vast majority of scenarios ZippyDB­™ pricing will be less than Azure and Redis Labs, while simplifying Development, DevOps, Testing and IT work considerably.
