Why am I Seeing a New Data Transfer or Network Charge on My Redis Cloud Bill?

Redis Cloud surfaces cloud provider (CSP) network usage costs as part of your overall billing when data is transferred between your application and Redis databases, or across regions and availability zones. These charges may appear as a new “data transfer,” “network,” or “egress” line item depending on your plan, contract timing, and architecture.

This article explains what these charges represent, what changed in Redis Cloud billing for certain plans, and how to investigate and reduce unexpected costs through Step-by-Step Instructions and troubleshooting.

Quick Fix Table

Prerequisites

Before investigating billing changes, ensure you have:

• Access to the Redis Cloud Console

• Visibility into your subscription type and contract date

• Access to your cloud provider (AWS/GCP/Azure) billing or networking view

What are data transfer or network charges?

Data transfer charges (also called network or egress fees) are costs from your cloud provider for moving data:

• Between your application and Redis databases

• Across availability zones within a region

• Between regions (for example, Active-Active deployments)

• Across VPCs or cloud providers

Important:

• These fees are charged by AWS, GCP, or Azure

• Redis does not mark up these costs

• Redis Cloud passes them through at CSP list price

When charges typically apply:

• Application and Redis are in different availability zones

• Cross-region replication or Active-Active is enabled

• VPC peering or networking crosses AZ or region boundaries

• Data migration between clouds or regions

When charges may not apply:

• Application and Redis are co-located in the same region and availability zone (depends on CSP rules)

What changed in Redis Cloud billing (August 1, 2025)

For direct Redis Cloud Pro or Annual contracts, billing changed starting August 1, 2025:

Before August 1, 2025

• Usage consumed prepaid credits

• Network charges billed separately (often via credit card)

• Costs split across multiple billing mechanisms

On or after August 1, 2025

• Usage and network charges are combined

• Both are deducted from cloud credits

• Network charges are billed at list price (1 credit = $1)

• Single invoice with unified visibility

What this means for you

• Network charges may now appear as a new visible component

• You may see faster credit consumption if network usage is high

• This is not a new fee, but a change in how it is surfaced and billed

Not impacted

• Existing contracts (pre-August 1, 2025) until renewal

• AWS Marketplace or GCP Marketplace subscriptions

• Redis Cloud Essentials plans

• Azure Managed Redis

How these charges appear in Redis Cloud

Depending on your plan:

Direct Pro or Annual (new contracts)

• Network charges are included in credit consumption

• May appear as a separate labeled component in billing views

Direct Pro or Annual (older contracts)

• Network charges billed separately

• May still appear in reporting but not deducted from credits

Marketplace or Essentials plans

• Network charges follow CSP billing rules

Common scenarios that cause new or increased charges

Architecture changes

• Application moved to a different availability zone

• Active-Active enabled across regions

• New VPC peering configuration

• Cross-cloud migration or replication

Contract renewal or new subscription

• Network charges now included in credits

• Previously separate costs now visible in one place

Increased or unplanned traffic

• Higher cross-zone or cross-region communication

• Larger payload sizes or increased request volume

Step-by-Step: Investigate a new data transfer charge

Step 1: Identify your billing model

• Determine if you purchase Redis Cloud:

  • Direct subscription

  • AWS/GCP Marketplace

  • Azure Managed Redis

• Check your contract date:

  • Before August 1, 2025 → legacy model

  • On or after August 1, 2025 → unified credits model

Step 2: Review usage vs. network consumption

• Compare:

  • Total usage (database operations, storage)

  • Network/data transfer usage

• Look for:

  • Sudden increases in network percentage

  • Faster-than-expected credit consumption

Step 3: Validate deployment topology

Check:

• Region alignment between application and Redis

• Availability zone alignment

• Active-Active or replication configuration

• VPC peering setup

Misalignment in any of these areas is the most common cause of increased network charges.

Step 4: Check cloud provider metrics

In your CSP console:

• Review outbound data transfer (egress)

• Filter by:

  • Region

  • VPC

  • Subnet or service

Map this traffic back to your Redis deployment.

Reducing data transfer costs

Co-locate compute and Redis

• Use the same region and availability zone whenever possible

Limit cross-region traffic

• Use Active-Active only when required for latency or resiliency

Optimize data patterns

• Reduce payload sizes

• Avoid unnecessarily large keys or responses

Align network architecture

• Review VPC peering and routing paths

• Avoid unnecessary cross-AZ traffic

Troubleshooting

New network charge appeared

• Likely caused by contract change or increased cross-zone traffic

• Confirm billing model and topology

Credits depleting faster than expected

• Network usage higher than estimated

• Review recent traffic patterns and deployment changes

Separate network invoices still exist

• You are likely on a legacy contract or marketplace plan

Unexpected spike in CSP bill

• Check for:

  • Cross-region replication

  • Migration activity

  • Misaligned AZ placement

Summary

Data transfer or network charges in Redis Cloud reflect cloud provider egress costs, not additional Redis fees.

These charges may appear new because:

• Billing has shifted to a unified credit model, or

• Your architecture is generating more cross-zone or cross-region traffic

Understanding your billing model and deployment topology is key to identifying and controlling these costs.
