Choosing between Memorystore vs Compute Engine Redis Costs is crucial for GCP users building caching layers or session stores. Memorystore offers fully managed Redis with predictable pricing, while Compute Engine lets you self-host Redis on VMs for potential savings. This comparison dives deep into costs, revealing which option delivers the best value for your needs.
Many teams overlook hidden factors like management overhead and scaling in Memorystore vs Compute Engine Redis Costs. Understanding these helps avoid surprises in monthly bills. Whether you’re starting small or scaling to production, this guide provides benchmarks and calculations to optimize your Redis setup on Google Cloud.
Understanding Memorystore vs Compute Engine Redis Costs
Memorystore provides a fully managed Redis service on GCP, handling backups, scaling, and high availability automatically. In contrast, Compute Engine requires you to provision VMs, install Redis, and manage everything yourself. This fundamental difference drives the core of Memorystore vs Compute Engine Redis Costs.
Memorystore charges per GB of memory provisioned, with tiers like Basic and Standard affecting availability and features. Compute Engine costs stem from VM instance types, storage, and networking. For small workloads under 10 GB, Memorystore often edges out in simplicity, but larger setups may favor Compute Engine for customization.
Key Factors Influencing Costs
- Provisioned memory vs actual usage
- High availability requirements
- Network egress and data transfer
- Management time and operational overhead
Memorystore Pricing Tiers Explained
Memorystore for Redis offers Basic and Standard tiers, plus Cluster mode for advanced needs. Basic Tier suits development with standalone instances, while Standard provides 99.9% SLA via zonal replication. In Memorystore vs Compute Engine Redis Costs, these tiers set the baseline for managed pricing.
Basic Tier starts at $0.027 per GB/hour for M2 instances in regions like Iowa. An 8 GB instance costs about $0.22/hour or $160 monthly. Standard Tier jumps to $0.046/GB/hour for similar sizes, adding failover for production reliability.
Cluster Pricing Details
Redis Cluster mode bills per node. A highmem-medium node at $0.1923/hour per node means a 5-shard setup with replicas hits $1.92/hour. Add AOF persistence or backups for 10-20% more. These rates make Memorystore scalable but premium-priced.

Compute Engine VM Costs for Redis
Running Redis on Compute Engine involves selecting machine families like E2 for cost-efficiency. E2 offers up to 128 GB RAM at low rates, ideal for Redis caching. In Memorystore vs Compute Engine Redis Costs, self-managed VMs shine for memory-heavy workloads.
An e2-standard-4 (4 vCPUs, 16 GB RAM) costs around $0.134/hour on-demand. Add persistent SSD at $0.17/GB-month for persistence. Total for 16 GB Redis: under $0.20/hour, often cheaper than Memorystore Standard for equivalent capacity.
Machine Family Breakdown
| Machine Type | vCPUs | RAM | Hourly Cost (us-central1) |
|---|---|---|---|
| e2-micro | 2 | 1 GB | $0.0136 |
| e2-small | 2 | 2 GB | $0.0337 |
| e2-standard-8 | 8 | 32 GB | $0.268 |
Direct Cost Comparison Memorystore vs Compute Engine Redis Costs
Let’s break down Memorystore vs Compute Engine Redis Costs for common sizes. For 8 GB Basic Memorystore: $160/month. Equivalent E2 VM (8 GB RAM): $100-120/month with discounts, saving 25%.
At 64 GB scale, Memorystore Standard: $1,200/month. Compute Engine n2-standard-16 (64 GB): $800/month plus $50 SSD, totaling $850. Compute Engine wins by 30% here, but factor in your time for management.
| Capacity | Memorystore (Standard) | Compute Engine (E2/N2) | Monthly Savings |
|---|---|---|---|
| 8 GB | $173 | $122 | 29% |
| 30 GB | $657 | $450 | 32% |
| 100 GB | $2,190 | $1,500 | 31% |
Pros and Cons Memorystore vs Compute Engine Redis Costs
Memorystore Pros
- Fully managed—no patching or monitoring
- Built-in HA and auto-failover
- Seamless GCP integration
Memorystore Cons
- Higher per-GB costs
- Less customization (Redis 7.2 max)
- Region-locked scaling
Compute Engine Pros
- Lower raw costs with commitments
- Full Redis config control
- Flexible machine types
Compute Engine Cons
In Memorystore vs Compute Engine Redis Costs, self-hosting adds ops burden. Expect 10-20 hours/month on maintenance for production setups.

Real-World Scenarios Memorystore vs Compute Engine Redis Costs
For dev/test: Memorystore Basic 5 GB at $100/month beats VM setup time. Production cache (50 GB): Compute Engine saves $400/month but needs Sentinel for HA.
High-traffic e-commerce: Memorystore Cluster handles 12 Gbps throughput predictably. Custom fintech app: Compute Engine with C4D instances optimizes for low-latency at 40% less cost.
Hidden Costs in Memorystore vs Compute Engine Redis Costs
Memorystore adds egress fees for cross-region access and backup storage. Compute Engine incurs networking, snapshots, and engineer salaries. TCO analysis shows Compute Engine cheaper for teams with DevOps expertise.
Discounts tip the scale: Compute Engine committed use drops 50-70%. Memorystore lacks similar long-term deals, making Memorystore vs Compute Engine Redis Costs favor VMs for year+ commitments.
Scaling Impacts on Memorystore vs Compute Engine Redis Costs
Memorystore scales vertically to 300 GB or horizontally via Cluster, but each step incurs full node costs. Compute Engine autoscales with MIGs, sharing resources efficiently.
From 10 GB to 100 GB, Memorystore costs 10x while Compute Engine scales at 4x due to efficient RAM/CPU ratios. This makes Compute Engine superior for bursty growth in Memorystore vs Compute Engine Redis Costs.
Expert Tips for Optimizing Memorystore vs Compute Engine Redis Costs
- Use E2 or N2 machines for Redis—pair with preemptible for non-critical workloads.
- Enable Memorystore read replicas only for heavy reads.
- Monitor with Cloud Monitoring to right-size instances.
- Migrate to Compute Engine for >50 GB sustained use.
- Leverage Terraform for repeatable VM Redis deploys.
