When we're doing patch management or when we're reviewing kit (end-of-life), it gives us the ability to manage the data center from a desk. Before we had Device42, we'd have spreadsheets or somebody would have to continually to go to the data center and physically have a look at what's available where. If somebody bought or wanted to buy new kit — if they needed, for example, six U's of space, 10 network ports and five power ports — we'd have to visit the data center and have a look at where we could fit that in. With Device42, we don't need to do any of that. We just need an internet connection to get to the Device42 appliance and we can see where the space is and what the power availability is, as well as what network capacity we've got, in which rack. Everything is there.
The continuous discovery of the infrastructure means we are able to review, and we are able to mitigate things in a quicker fashion than we would have previously. If somebody had asked us five years ago how many Server 2008's we have, because we've got a vulnerability and we need to know how many servers we need to patch, it would have taken us some time to find that out. We would have had to go through all the different platforms and find out where we're hosting 2008 Servers. With Device42, we can go in and, within 10 minutes, tell the business how many servers we need to patch.
Also, the solution's CMDB, ITAM, and DCIM features create a single source of IT truth in our environment. These too make it a lot easier for the operations team. When incidents come up on the operations monitor, that team can easily ascertain who the owner is of these devices, where they sit, and who's responsible for them. They ensure the correct people get things looked at much quicker.
In addition, we're currently on a cloud project, so we have been using the solution to assess what we have in our environment, what we want to take to the new environment, what we need to drop in terms of hardware, the age of the hardware, as well as end-of-life operating systems or applications. It has helped us a lot with getting that kind of data.
We use the solution’s Application Dependency Mapping and that gives us some insight into a number of things. For example, if we're looking at a server that currently has a problem, the operations team can look at the Application Dependency Mapping and see what the server is part of in terms of the service. There may be a number of things that are connecting to it or that it's connecting to. That mapping gives us that insight into how parts of the infrastructure are talking to each other.
Previously, when it came to asset management, people would have been updating spreadsheets or documents about where they've moved things or what they've been doing, or they would have had to visit multiple areas to find out certain information. Device42 turns that into a hands-off approach to everything. We know it has been doing discovery continuously over evenings and weekends. So whatever data we are pulling out is fairly up to date. The time saved by using Device42, across the teams, is easily equivalent to a couple of people at least. A full-time member of staff would normally work seven-and-a-half hours every day so you're looking at 146 hours a month of savings, times two, of people not having to visit data centers to do things like capacity planning, auditing, etc.
We also use Device42 for internal audits. In that context, it saves a considerable amount of time. If we were to do it manually, we're looking at a couple of weeks' worth of work, but if we're doing it in Device42 we're probably looking at a couple of days' worth, maximum.
