We love open source at Device42. The Device42 product uses a number of open source technologies in its stack and Device42 developers actively contribute to open source as well. So please don’t look at the following comparison of Device42 and RackTables as a knock on open source software in general. Rather, we just want to provide an objective look at the key differences between this open source tool and Device42. We have also included some reviews from customers who have switched, and we sincerely hope you find this information helpful. If you don't have budget to buy Device42 - by all means, we recommend using the open source tool.
We’ve put together some info that will highlight the key differences between an Open Source solution like RackTables, and a Continuous Discovery Enterprise CMDB like Device42.
...is a full featured CMDB, includes an enterprise password management system, IT Asset Management (ITAM) and lifecycle management, DCIM tools like power monitoring and rack utilization heat maps, both SSL and TLS certificate management, End of Life (EOL) & End of Support (EOS) tracking, integrated IPAM, Continuous Discovery with in depth Application Mapping, Software License Management, countless out of the box integrations, Webhook support, and a powerful, well documented RESTful API…
With the majority of these features included in our core product!
While many enterprise tools claim to have auto-discovery built-in, there are key differences:
Device42 is agentless — You don’t have to find every device and put an agent on it. Device42 finds them for you.
Device42 takes a Holistic approach — connecting directly to your:
....and correlates the interrelationships and dependencies automatically.
e.g., if Device42 finds a MAC address on a switch port from a network device, it correlates that with a VM which is on a blade sitting in a particular slot in a chassis. It finds what services are on that machine, and calculates the dependencies on other machines and services on your network.
like most Open Source alternatives, you’re on your own to manually keep everything up to date, which we all know goes by the wayside way too often. This can be worse than no documentation at all. Trusting outdated and just plain wrong documentation can lead to bad decisions that result in embarrassing and costly outages. Device42 discovers changes to your infrastructure shortly after they’re made, automatically updating documentation on your behalf so it’s always up to date, and always correct.
...and its rack layouts are primitive, also lacking drag-and-drop rack arrangement.
Besides the Primitive Visualizations, lack of photo realistic views, and missing features, by all means, if you have no budget, use RackTables over a cobbled together Excel based solution… However, if you want a market leader in features, ease of use, discovery, and price - take a look at Device42.
RackTables just can’t match the functionality of Device42.
The modern IT infrastructure requires a modern tool.
With the advent of virtualization, containers, cloud computing, and software-defined networks...
IT infrastructure is orders of magnitude more complex than it was 10 years ago. Too much time is wasted trying to manage different tools.
It is no longer practical to manage your IT infrastructure using separate tools for:
The interrelationships are too important and too complex --
they can only be adequately captured by an integrated tool like Device42.
Device42 looks at your IT Infrastructure holistically
and gives you a single console to manage your data center (DCIM),
IP addresses(IPAM) and passwords in addition to ITAM (IT asset management), and has a built-in CMDB.
A true enterprise class solution should not be isolated. You likely use monitoring tools, automation tools, ticketing (ITSM) tools, finance tools, and others that can benefit from the information in your CMDB.
Many tools make integrating time consuming and/or expensive, and some don’t support it at all. With Device42, you get a plethora of integrations out of the box, plus webhooks & REST APIs that make it a breeze to integrate with other tools.
Though Open Source seems like a bargain at the beginning, the manual upkeep and constant attention it requires keeps costing you forever.
Device42 doesn’t believe an enterprise class product should require expensive professional services - and ours doesn’t. We also believe that the value you’ll get from Device42 far outweighs the cost.
And more than a thousand happy users in 33 countries agree. If our auto-discovery and collaboration features can save your team just ten hours per month, then Device42 will more than pay for itself.
