Google Memorystore Redis Pricing - Everything You Need To Know

Google Cloud Memorystore offers a fully managed, scalable Redis service to improve application performance and reduce database load. Understanding its pricing model is crucial to avoid unexpected costs. Memorystore pricing depends on capacity, network usage, regions, and other factors. This guide explains the pricing structure in depth.

Google Memorystore Pricing Overview

How Google Memorystore Pricing Works

Memorystore pricing has two main sections: instance pricing and network usage. No upfront fees are required.

  1. Instance Pricing: Cost primarily depends on the instance tier (basic or standard) and size. You're billed per GB-hour. The basic tier is cheaper but doesn't provide high availability or failover. The standard tier provides these features at a higher price.

  2. Network Usage: There is no charge for ingress traffic. However, egress traffic—data sent from your Memorystore instance to other Google Cloud services within the same region—is charged at a nominal fee. Inter-region and Internet egress are priced higher.

Prices vary by region and may change over time. Be sure to check the official Google Cloud Pricing page for the most recent and detailed information.

Different Components That Contribute to the Cost

There are several components that contribute to the overall cost of Google Memorystore:

1. Instance Type plays a large role in determining the cost. As mentioned earlier, the Standard tier offers better performance and high availability but comes with a higher price tag than the Basic tier.

2. Resource Usage is another key factor. The more resources (CPU, RAM) your instances consume, the higher the cost. Always right-size your instances to ensure you aren’t overpaying for unused capacity.

3. Network Egress costs can add up if you have significant data transfer out of the Memorystore to different regions or to the internet.

4. Operational Costs: While not directly tied to the Memorystore pricing, operational costs related to managing, monitoring, and troubleshooting your Redis deployments should also be considered as part of the TCO (Total Cost of Ownership).

Detailed Breakdown of Google Memorystore Pricing

Understanding the pricing structure of any cloud service is essential to budget effectively for your business. This rule applies no less to Google Cloud's Redis offering, known as Memorystore. In this section, we'll delve deeper into the various factors influencing the cost when using this fully managed in-memory data store service.

Pricing by Region

The cost of using Google Memorystore varies by region due to local demand, supply, and operational costs. For example, Memorystore instances hosted in the "us-central1" region may come at a different price than those in "europe-west2".

To locate the most current pricing rates in your preferred region, navigate to Google Cloud’s official Pricing Calculator here. Just enter 'Memorystore' in the product description, select your region, and adjust parameters such as instance size and duration. The calculator will provide you with an estimate.

Pricing for Different Instance Types

With Google Memorystore, you can choose between two types of Redis instances — Basic tier and Standard tier.

  • Basic Tier: This tier is a standalone Redis instance, ideal for development and testing environments or applications with light traffic. Costs are lower because it doesn't include failover support. If high availability isn’t a crucial factor for your use case, this could be an economical choice.

  • Standard Tier: This tier provides a more robust service with high-availability and automatic failover. It has two nodes, a primary and a replica, located in two different zones for redundancy purposes. In case the primary node fails, the service automatically switches to the replica node, hence providing uninterrupted service. This makes the Standard tier more suitable for applications requiring higher reliability and uptime.

Remember that each tier comes with different sizes (Memory Capacity) ranging from 1GB to 300GB for both tiers, which will also affect the overall cost.

Network Costs Involved

Google Memorystore does not impose charges for incoming network traffic (ingress) but does apply fees for outgoing traffic (egress). However, egress within the same zone or region (i.e., VPC Network Peering) is typically free, while cross-region and internet egress incur costs. Keep this in mind when architecting your applications to minimize unnecessary data transfers across regions.

Data Storage and Backup Costs

The cost of your chosen memory capacity includes data storage. However, if you enable the optional Redis RDB snapshot feature for point-in-time recovery, there will be additional charges for the storage used by the snapshots.

Remember, though, backups are vital for preventing data loss, particularly in production environments. Weigh the costs against the benefits to determine what's best for your specific use case.

In conclusion, understanding Google Memorystore's pricing structure involves considering multiple elements, including regions, instance types, network and storage costs. These should all factor into your deployment decision-making process.

Tips to Control and Optimize Google Memorystore Costs

Navigating cloud costs can be daunting even for seasoned developers. Here are some strategies to get the most value from your Google Memorystore resources:

Monitor usage with tools like Cloud Monitoring to assess and right-size your configuration. This can significantly reduce costs.

Enable auto-scaling to match supply with demand. This prevents over-provisioning during low traffic periods.

Use Committed Use Contracts for long term consistent usage. These provide discounted rates via 1-3 year commitments.

Leverage Sustained Use Discounts. Google automatically gives discounts when you use services heavily each month.

Evaluate regions carefully. Memorystore pricing varies across regions so choose one that optimizes costs.

Continuously adjust your strategies based on changing needs and offerings. What works today may need tweaking tomorrow. Monitoring usage and optimizing resources are key for efficient cloud cost management.

Comparing Google Memorystore Pricing With Other Services

When choosing in-memory data stores, the main options are Google Memorystore, Amazon ElastiCache, and Azure Redis Cache. While similar, their pricing models differ. Understanding these variations helps pick the right service.

Google Memorystore charges based on capacity, network usage, and features. Prices start around $0.046/hour for standard instances in US regions.

Amazon ElastiCache charges per node type, number of nodes, and data transfer. Prices start at $0.027/hour for cache.t3.micro instances in US East.

Azure Redis Cache charges per cache size, operations, and data transfer. Basic tier pricing starts at $0.022/hour for C0 caches in US.

While the core pricing components are alike, some key differences exist around scaling, data transfer, and backup costs.

When comparing, also consider performance, compatibility, scalability, locations, and support levels. Choose based on your specific business needs, not just price. The cheapest option isn't necessarily the most cost effective long-term.


Memorystore provides a robust Redis service with seamless Google Cloud integration. Evaluating the return on investment and optimizing usage is key. Understanding the pricing model equips you to tailor deployments to your needs and budget. Whether it's a high traffic website or simple blog, you can now make informed decisions about this in-memory data store service.

Frequently Asked Questions

What is the difference between Memorystore standard and basic tiers?

The Standard tier offers high availability with automatic failover while the Basic tier lacks these features. The Standard tier is more suitable for production environments needing reliability.

What is the difference between GCP Memorystore and Redis?

Memorystore is Google Cloud's fully managed Redis service. Redis is an open-source in-memory data store that Memorystore makes easier to use at scale on Google's infrastructure.

Does Google provide tools to monitor Memorystore costs?

Google offers general tools like Cloud Console and Billing Reports to monitor usage and costs of services including Memorystore. These help track spending and set budget alerts. There are no Memorystore-specific tools available currently.

How are data transfer costs handled in Google Memorystore?

Ingress is free but egress charges apply based on traffic leaving the region, with higher costs for inter-region and internet traffic. Minimizing unnecessary cross-region transfers can reduce costs.
