Getting your hands dirty with real networking stuff can be tough. Building a physical lab with routers, switches, and firewalls? That's often pricey, eats up a ton of power, and is a beast to manage. Virtual network labs, powered by emulators like EVE-NG (Emulated Virtual Environment - Next Generation), offer a much better way.
EVE-NG lets you mimic real-world network setups using actual operating system images from the vendors, and you can get to it all from your web browser. You can build and test complicated setups with virtual Cisco, Juniper, Fortinet, Palo Alto Networks, and other devices. It's great for getting ready for certifications (like CCNA, CCNP, CCIE), testing out new ideas for your company, or just learning new tech.
EVE-NG is pretty powerful, but setting it up and managing it on your own machine needs some serious hardware and technical know-how. That's where CloudMyLab comes in. We offer hosted EVE-NG environments that are already built, tuned up, and supported. This means you can skip all the setup headaches and just focus on learning, testing, and innovating.
For business and IT leaders, putting money into tools for network training, testing, and making sure things work is important for keeping things running smoothly, cutting down on risks, and sparking new ideas. EVE-NG, especially when you get it through a managed service like CloudMyLab, is a really strong business move.
Lets see how EVE-NG compares head-to-head with other popular tools especially for big, multi-vendor enterprise deployments:
Strengths | Downsides |
Real Vendor OS Emulation: EVE-NG runs unmodified Cisco IOS/IOS-XE, Juniper Junos, Palo Alto PAN-OS, Fortinet FortiGate, Arista EOS, and more inside QEMU, Docker, or IOL/IOU containers. | Hardware Needs: To smoothly run 50 simultaneous virtual devices, plan for at least 16 vCPUs, 64 GB RAM, and NVMe storage on your virtualization host. Going bigger often means clustering multiple hosts. |
Scalability: EVE-NG supports topologies of 50–200+ nodes on a single virtual host (depending on hardware). The Pro edition lets you cluster multiple servers to handle hundreds of nodes and get high availability. | Scalability: EVE-NG supports topologies of 50–200+ nodes on a single virtual host (depending on hardware). The Pro edition lets you cluster multiple servers to handle hundreds of nodes and get high availability. |
Browser-Based GUI: No chunky client software needed. Users connect via any modern browser, simplifying remote access and onboarding. Teams in different locations can log in immediately. | Image Licensing & Management: You're responsible for getting legal OS images, formatting them correctly, and keeping your image library organized. Frequent version updates mean ongoing tracking and replacement. |
Multi-Tenant Resource Controls: Admins can set CPU, RAM, and storage limits per lab, stopping one team's huge POC from starving others. | |
Advanced Features (Pro Edition): Includes snapshots for quick rollbacks, lab sharing for collaboration, and multi-server clustering for distributed resources. |
Strengths | Things to Consider |
Community: GNS3 has been around for over a decade, so there's a huge library of tutorials, pre-built topologies, and an active user forum. Many Cisco-focused network engineers love it. |
Limited Multi-Vendor Support: While you can run Juniper vJunos or Palo Alto images, it's often less smooth and needs more manual tweaking than EVE-NG. |
Open-Source & Free: No licensing fees for the software itself. | Scalability Limits: For labs over 50 nodes, GNS3 can hit performance bottlenecks, especially when mixing QEMU and Dynamips nodes. The community edition doesn't have built-in clustering. |
Cisco IOL & IOU Support: Works well with older Cisco IOS images, which can be useful if your environment still uses legacy gear. | Needs a Local Client: Users have to install the GNS3 GUI on their workstations (Windows, macOS, or Linux), which adds complexity for remote collaboration. |
Strengths | Things to Consider |
Cisco-Designed & Free for Students: Made for CCNA/CCNP learning, Cisco gives it away free to Networking Academy students. It's lightweight and easy to install. | Cisco-Only Simulation: Packet Tracer uses a simplified simulation engine, not real IOS or NX-OS code. Advanced features (like BFD, EVPN-VXLAN, advanced QoS) simply aren't there. You can't import third-party OS images. |
Simple Interface: Drag-and-drop simulation helps beginners quickly visualize traffic flows and basic routing. | Not for Enterprise POCs: Since it doesn't run real vendor code, anything beyond basic topology design or entry-level configs won't accurately translate to a production environment. |
Strengths | Things to Consider |
Official Cisco Solution: Runs sanctioned Cisco IOS/XE/XR, NX-OS, and SD-WAN images with active support directly from Cisco. Integrates well with Cisco’s DevNet tools and APIs. | Cisco-Only: CML only uses Cisco images. If you need to test multi-vendor interoperability, you'll need another tool. |
High Availability & Clustering: Enterprise CML versions support clustering across multiple servers with central management. This makes it a direct competitor to EVE-NG Pro for Cisco-heavy environments. | License Cost: CML’s licensing is pretty pricey compared to open-source EVE-NG Community. You pay for Cisco’s official support and recurring renewals. |
Automation Integration: Exposes REST APIs for automatically building, configuring, and tearing down labs—great for CI/CD pipelines in Cisco-heavy infrastructures. | Hardware Overhead: Like EVE-NG, CML needs beefy servers (typically 16+ vCPUs, 64 GB+ RAM, fast SSDs). Testing non-Cisco devices needs additional emulators. |
For enterprises needing real multi-vendor emulation, huge scalability, and a single, browser-based management interface, EVE-NG is a top contender. Its ability to host hundreds of real vendor OS instances, combined with advanced multi-tenant controls and clustered hypervisors (in the Pro edition), makes it a strong choice for corporate labs, training departments, and important POC environments.
Running EVE-NG effectively on your own is demanding (think multi-core CPU, 16GB+ RAM, fast SSD). Getting and legally managing device images also takes effort. CloudMyLab’s hosted EVE-NG gets rid of these headaches.

You'll need to install EVE-NG on either a bare-metal server or as a virtual machine using something like VMware ESXi or VMware Workstation. Installation isn't super complicated, but you'll want to follow the official guide closely to get everything configured right.
Hardware Sizing (Example for a 50-Node Lab):
You'll need to upload and configure images for the devices you want to emulate (Cisco IOS, Juniper, Palo Alto, etc.). Get legal, licensed images for your network devices, format them correctly, and upload them to EVE-NG.
Once the base setup is complete, you'll set up EVE-NG's networking, licensing (for Pro), and performance settings. See our support documentation on EVE-NG console options for accessing your devices.
Or, you could just use CloudMyLab’s hosted EVE-NG environments for an instant, pre-configured solution.
