Cloud SQL Committed Use Discounts (CUDs)
At its core, CUDs serve as an enticing opportunity for businesses to gain access to substantial discounts on Cloud SQL services, in return for a commitment to continuous usage of database instances in a designated region over a one- or three-year term.
Does your workload have predictable resource needs? If yes, Cloud SQL CUDs are just the right fit for you.
The idea is simple – commit to a constant usage rate, computed as cost per hour of similar on-demand spending over the chosen commitment term. In return, you receive an attractive discount rate on Google Cloud SQL for the usage encompassed by your commitment.
The flexibility of Cloud SQL CUDs is another crucial aspect:
- Once you purchase these from any Cloud Billing account, these discounts extend to any eligible usage across all projects that the account finances.
- This arrangement remains stable even if the price of the relevant usage alters during the commitment term.
- The commitment fee, which is billed monthly, stays constant throughout the term, and you continue to enjoy the same discount rate on the applicable usage despite any price changes.
A word of caution though: exceeding your usage above the committed level will result in charges at the standard on-demand rate.
Cloud SQL CUDs – Discounts & Pricing
When it comes to financial feasibility, CUDs are a game-changer offering 25% and 52% discounts off the on-demand rates for one-year and three-year commitments respectively. This level of discount is consistent across all regions and has a significant impact on reducing your Cloud SQL expenses.
In this section, we’ll dive deeper into the cost dynamics by considering a specific instance in the South Carolina region (US east-1). Understanding the intricacies of CPU and memory pricing under various commitment levels will arm you with the necessary knowledge to make economically sound decisions.
Savings from Cloud SQL Committed Use Discounts (CUDs)
Start your process of economical computing with Cloud SQL CUDs. These tailored plans offer considerable savings over the on-demand pricing, which makes them an excellent option for steady workloads. This section is a guided journey into the landscape of savings that you can reap with one and three-year commitments, compared to on-demand pricing.
SQL Server – Live Examples
To illustrate this effectively, let’s consider a real-world scenario. You’re operating 100 instances across two different regions. Each instance is utilizing 2 high availability (HA) vCPUs and 7.5GB HA RAM. For the purpose of this illustration, let’s focus on South Carolina region (us-east1), and let’s assume that you’re interested in buying a one-year CUD.
Let’s dive into the specifics:
- Number of instances: 100
- Region: South Carolina (us-east1)
- HA vCPUs per instance: 2
- HA RAM per instance: 7.5GB
We can utilize this information to calculate the approximate total hourly commitment cost for your set of instances:
|Component||On-Demand Pricing||One-Year CUD (25% Discount)||Three-Year CUD (52% Discount)||Monthly Cost (On-Demand)||Monthly Cost (One-Year CUD)||Monthly Cost (Three-Year CUD)|
|100x 2 HA vCPUs||$16.92/hr||$12.69/hr||$8.12/hr||$12,351/mo||$9,264/mo||$5,929/mo|
|100x 7.5GB HA RAM||$11.21/hr||$8.41/hr||$5.38/hr||$8,181/mo||$6,136/mo||$3,926/mo|
Note: The prices are calculated per component per hour and are billed as per your local currency. Monthly costs are based on an average of 730 hours per month.
How much can I save with Cloud SQL CUDs?
- To bring these numbers to life, with on-demand pricing, your total monthly cost would be approximately $20,532.
- With a one-year CUD, this drops significantly to $15,400 – translating into an impressive savings of around $5,132 per month.
- For a three-year CUD, the savings are even more substantial, dropping your monthly cost to $9,855, and thus saving you approximately $10,677 per month compared to on-demand pricing.
Do keep in mind, once you make the commitment, you’re charged that amount even if you decide to reduce the number of vCPUs or RAM during the month. However, the cost savings and predictable expenditure model often outweigh this factor for steady workloads.
Recommendations for Using Cloud SQL CUDs
Exploring the financial terrain of Cloud SQL CUDs is an important step towards understanding how to optimize your cloud expenses. However, to get the most out of these discounts, it’s critical to comprehend their implications and usage guidelines.
The power of Cloud SQL CUDs lies in their application towards vCPUs and memory, making them a strategic tool for reducing your database operational costs. But, as with any powerful tool, it’s crucial to use it effectively.
Key points to remember:
- Cloud SQL CUDs apply only to vCPUs and memory.
- These discounts do not extend to storage, backups, IP Addresses, network egress, or licensing.
- Cloud SQL CUDs blanket all instances in a specific region.
- These discounts are measured in dollars per hourly on-demand commitment.
Recommendations Before Purchasing Cloud SQL CUDs
When making the decision to purchase CUDs, it’s wise to factor in the following considerations:
- Regions: CUDs are purchased per region. If you’re operating in multiple regions, calculate and secure CUDs for each region independently to maximize savings.
- Projects: Ascertain the consistent baseline of vCPU/RAM usage for each project. Bear in mind that production loads often run 24/7, while development or staging environments might operate more intermittently.
- Instances: Cloud SQL instances are typically run continuously, making it common practice to buy CUDs for 100% consumption. However, if you have instances running only for shorter durations or burst usage, exclude them from your CUD calculations, paying on-demand rates for these instances instead.
- Machine types: CUDs aren’t tethered to any specific machine type. They are linked to the total amount of vCPUs and memory used in the region, giving you the flexibility to adjust your resources as needed without impacting your discount.
With a clear understanding of their usage and the precise application of these recommendations, you can maximize your savings and effectively optimize your Cloud SQL operational costs.
