Azure Virtual Machines – Upgrading E Series Machines to Ev5

Jan 14, 2025

Azure

Compute

Azure offers several improvements with the latest Ev5 series virtual machines, providing better price-performance and enhanced capabilities compared to previous generation E series machines. This policy recommends upgrading to newer Ev5, Edv5, Esv5, or Edsv5 series VMs to optimize cloud infrastructure costs and performance.

Why Upgrading Matters

The Ev5 series virtual machines deliver significant advantages:

Processor Improvements: Leveraging newer Intel Xeon Platinum 8370C processors

Performance Boost: Up to 30% better performance compared to previous generations

Memory Optimization: Similar or improved memory configurations

Cost-Neutral Upgrades: Often available at comparable pricing to older series

Cost Reduction Potential

Upgrading to Ev5 series can yield substantial benefits:

Example Scenario: E64 v4 machine (64 vCPUs, 504 GB RAM)

Current Monthly Cost: $2,943 (East US region)

Upgrade to E64 v5: Same monthly cost, increased memory to 512 GB

Additional Performance: Newer processor architecture

Potential Cost Savings Breakdown

Processor Efficiency: 20-30% improved computational performance

Power Consumption: Lower energy requirements per compute unit

Infrastructure Consolidation: Potential for reduced total VM count

Implementation Guide

Infrastructure as Code Upgrade (Terraform Example)

# Before (Older Generation)
resource "azurerm_virtual_machine" "example" {
&nbsp; vm_size = "Standard_E64_v4"
&nbsp; # ... other configuration
}
<h1>After (Upgraded Generation)</h1>

# Before (Older Generation)
resource "azurerm_virtual_machine" "example" {
&nbsp; vm_size = "Standard_E64_v4"
&nbsp; # ... other configuration
}
<h1>After (Upgraded Generation)</h1>

# Before (Older Generation)
resource "azurerm_virtual_machine" "example" {
&nbsp; vm_size = "Standard_E64_v4"
&nbsp; # ... other configuration
}
<h1>After (Upgraded Generation)</h1>

Manual Upgrade Steps

Verify current VM series and specifications

Check compatibility with existing workloads

Plan maintenance window for migration

Create snapshot of existing VM

Perform staged migration

Validate application performance post-upgrade

Best Practices

Gradual Migration: Upgrade non-critical workloads first

Performance Testing: Benchmark applications before and after upgrade

Cost Monitoring: Use tools like Infracost to track potential savings

Reserved Instances: Reassess after upgrading to optimize further

Practical Implementation Examples

Scenario 1: High-Performance Computing

Before: Standard_E64_v4 with legacy processor

After: Standard_E64_v5 with improved computational efficiency

Result: Same cost, 30% performance improvement

Scenario 2: Memory-Intensive Applications

Before: 504 GB RAM on older generation

After: 512 GB RAM with newer processor

Result: Enhanced memory and processing capabilities

Considerations and Caveats

Potential limitations to consider:

Application Compatibility: Some specialized software might require testing

Migration Complexity: Potential downtime during upgrade

Licensing Implications: Verify software licensing requirements

Regional Availability: Not all VM sizes available in all regions

When to Avoid Immediate Upgrade

Highly specialized workloads with specific hardware dependencies

Systems with complex, tightly-coupled configurations

Environments with strict change management protocols

Monitoring and Optimization

Recommended Tools:

Azure Cost Management

Infracost (for proactive cost detection and optimization)

How difficult is it to upgrade to Ev5 series? Most upgrades are straightforward, typically involving changing the VM size in your configuration.

Will I see immediate cost savings? While direct cost savings might be minimal, performance improvements can lead to indirect cost reductions

Are there risks in upgrading? Minimal risks if proper testing and staging are performed. Always create backups and test in non-production environments first.

How does Infracost help with these upgrades? Infracost can automatically detect opportunities for VM series upgrades during infrastructure code scanning, helping you proactively optimize cloud costs.

What if my specific workload doesn’t benefit from the upgrade? Performance varies. Always conduct thorough testing and benchmarking specific to your use case.
