Choosing the right EVE-NG server package is key to getting the performance you need for your virtual labs. Too small, and your labs are slow. Too big, and you're wasting money. CloudMyLab's EVE-NG Resource Calculator changes that. In under 2 minutes, you'll know exactly what CPU, RAM, and storage your lab needs. No guesswork. No waste.
EVE-NG resource calculators are essential tools for IT pros running virtual network labs. They help you estimate exactly how much CPU, RAM, and storage you'll need. This stops you from guessing – no more undersizing a server only to have labs crawl, and no more buying way more resources than you actually need. Calculators take the guesswork out, giving you recommendations tailored for stable lab performance.
Getting the resource calculation right matches what you need technically with your budget. Being precise saves you money without compromising the resources essential for your labs to run smoot
Here's the brutal truth: 73% of network engineers overprovision their EVE-NG environments by at least 35%. That's money burning in your data center.
The flip side? Underprovisioned labs crash during critical certification studies or POC demos. Neither option works.
Overprovisioning means you're essentially lighting money on fire, paying for resources that sit idle. Meanwhile, underprovisioning creates a different nightmare. Your carefully planned lab grinds to a halt just when you need it most. Devices timeout. Connections drop. Your productivity tanks.
Let's cut through the confusion. Accurate EVE-NG resource planning starts with understanding what actually drives performance in virtualized network environments.
Your EVE-NG deployment isn't just about raw CPU cores and RAM. The type of devices you're simulating matters enormously. A Palo Alto Networks virtual firewall performing deep packet inspection will crush a server that handles basic Cisco routers just fine. Traffic patterns matter too - a lab running BGP full tables has vastly different requirements than one doing simple OSPF testing.
CloudMyLab discovered this through painful experience. After deploying thousands of EVE-NG environments, we noticed patterns that generic calculators miss. For instance, mixing vendor platforms creates unexpected resource spikes. Running Cisco and Juniper devices together requires 30% more resources than running them separately - something you won't find in any standard sizing guide.
Here’s how it works, usually in two steps:
Step 1: Pick your devices and how many
First off, you select the devices you plan to include in your lab from our huge library. We have profiles for over 200 different network appliances, everything from basic routers to complex firewalls and security platforms. Importantly, each profile reflects how much resources that device actually uses, not just some marketing spec.
Step 2: Get instant recommendations
Once you’ve selected your planned devices and quantities, the calculator gives you precise specifications:
To run network simulation projects effectively, you really need to think about how big and complex the environment you plan to build is going to be. The EVE-NG resource calculator helps nail down those exact requirements by looking at things like the number of devices, how much load you expect, and potential traffic.
Knowing the scope of your project is key to picking the right server. Figure out how many devices you'll need, how many people might use the lab at the same time, and how much traffic you expect, as these numbers affect the server workload. Also, consider your long-term goals. Will you need to add more devices later? Thinking about things like redundancy for critical labs helps prevent buying a server that's too small from day one.
Traditional EVE-NG lab sizing guides treat every deployment like it's identical. They hand you generic formulas that ignore the reality of vendor-specific requirements, traffic patterns, and user behavior. A Cisco ASAv firewall just doesn't use resources the same way a Juniper vMX router does, but many planning tools don't recognize that.
CloudMyLab's pricing is set up to fit different needs. The resource calculator helps you match server capabilities with the size of the lab environment you need to build. It helps you find the right balance between the computing resources you get and the cost, pointing you to the optimal server package.
You're trying to hit that sweet spot between having enough power and not spending too much. An underpowered server means frustration and lost productivity. An overpowered one costs extra for resources you don't use. CloudMyLab's resource calculator helps you find this balance, making sure your investment aligns with the performance you need for your specific use case.
Let’s look at a couple of examples:
This is a common setup for certification study or simple POCs – a few routers and switches, maybe a firewall.
Say you're building a lab with:
Using the CloudMyLab EVE-NG resource calculator online, you'd select these devices and see something like this:
Here's what the calculator tells you:
Resource Planning: It automatically adds up the CPU and RAM for your selected devices. For this lab, you'd need at least 4 vCPUs and 6 GB RAM just to run the devices.
Picking a package: The calculator suggests a package like the Medium (16 CPU, 32GB RAM, 160GB SSD). That gives you plenty of headroom to add more gear later – maybe a couple more routers for OSPF, extra switches for Spanning Tree practice, or other service devices.
You can, of course, tweak the operating system running your EVE-NG instance or choose different billing cycles (hourly, monthly, etc.).
Scenario: You're prepping for the CCNP ENCOR exam and need a more complex lab.
Topology:
If you enter these into the calculator, the total resource requirements come to around 30 vCPUs and 76GB RAM. If you looked at traditional sizing guides, they might suggest you need a massive server with 128GB RAM and 48 cores "just to be safe" – often overkill.
Our calculator shows a different story: CloudMyLab's Intel Fox-24 package (24 CPUs, 96GB RAM, 480GB SSD), for example, can handle this lab perfectly. At a competitive price, you get enterprise-grade performance without needing to buy enterprise-grade hardware yourself.
They estimate the CPU, RAM, and storage needed for virtual network labs based on the devices you plan to include and your usage needs.
It ensures your lab performs well and saves you money by avoiding buying too many resources or too few (which makes the lab unusable).
Think about the size and complexity of your planned lab – the number and type of devices. Consider how many people will use it at once. Our calculator helps you translate that into CPU, RAM, and storage needs.
Consider the processing power (CPU/RAM) offered, if you can scale resources up later, the level of support and uptime guarantee, and how the price fits your budget for the resources you get.
