3. Network security
Knowledge about cyber security products and services—as well as the threats they guard against—never go out of fashion. Organizations are facing a barrage of threats against their networks and data centers, so finding people with related skills remains a high priority.
“Companies are constantly having to pay attention to their security as more and more cyber attacks happen,” Vick says. “That is something that is not slowing down, so they are having to update their firewalls and other security features.”
Enterprises are building out their security teams, in some cases looking for people to update their security posture with a variety of technologies. “Vulnerability management is a role that we have seen become more and more prevalent within organizations,” Vick adds.
Even as companies bolster their security, “threats are advancing in numbers, sophistication, and severity,” according to Leary. “Networks represent a primary conduit for threats, and data centers represent a principal target. Staff members across all IT disciplines (including development, networking, and support), should have a ‘minor’ or even a ‘double major’ in security. This is extremely valuable to their organization, their peers, and their own advancement.”
Unfortunately, the defenses that worked well in the past might no longer be sufficient for modern infrastructures. “Security is too important to just rely on the firewall to keep you secure,” says Darrin Thomason, a vice president and solution architect at Arista Networks. “The modern professional needs to understand the different observability capabilities along with threat mitigation options that will help reduce the attack surface from a security standpoint,” Thomason says. These might include tools that prevent an infiltration in one network segment from spreading to another area.
4. Proactive and holistic infrastructure management
The ability to solve problems, mitigate threats, deploy systems, and monitor services are all good tactical skills to have, Leary says. “However, IDC research shows that proactive infrastructure management skills are as or more valuable to IT organizations as traditional tactical maintenance, repair, and operations skills,” he says.
Staff members that enable networks and data centers to avoid problems, prevent attacks, optimize resources, model innovations, and adapt readily drive a more resilient and responsive digital infrastructure, Leary says.
Holistic management is also important. “In today’s hyper-connected digital business environment, the technology infrastructure must be designed, developed, operated, secured, and evolved as a concert—not as a siloed collection of piece parts,” Leary says. “The whole must exceed the sum of the parts.”
Staffers that serve to solidify just one siloed technology domain do not serve the greater IT good, “and certainly do not serve the worker, customer, or smart device whose experience depends on the infrastructure working unison,” Leary says.
Skills related to managing end-to-end performance for digital experience, integrating management tools for network and security observability, and collecting and sharing infrastructure intelligence for network or application data, for example, are useful in delivering concerted IT outcomes, Leary says.
5. Network design/architecture and hardware
Organizations need to be able to design or redesign their networks as they grow or contract. They need people who are fluent in design and architecture concepts. “Usually, these people need to understand firewalls, have experience with routers and switches, and general network usability and design,” Vick says. “The top skills are virtualization, scripting, cloud computing, and network hardware,” including equipment for LANs, WANs, TCP/IP, etc.
Although data center and networking environments have gone heavily virtual over the years, hardware is still vital. “Data centers are integral to setting up a scalable and secure network, and anyone working in a data center must know how to build out networking hardware,” says Nick Kolakowski, senior editor at talent site Dice.
Wireless network design, deployment, operation, and optimization are outpacing traditional wired networking skills in demand, Leary says. “We are moving rapidly to a wireless-first environment, for end user, smart device, and even adjacent building/site connectivity,” he says. Deploying, operating, and optimizing wireless networks, previously a one-time vendor set-up exercise, is now a continuous management process fueled by smarter wireless systems, automated management, sophisticated threats, and shifting demands, Leary says.
6. Platform engineering
Platform engineering is an emerging technology approach that can speed up the delivery of applications and the pace at which they produce value, according to Gartner.
It enhances developer experience and productivity by providing self-service capabilities with automated infrastructure operations, Gartner says. Platform engineering is on the rise in part because of its promise to accelerate the delivery of value by product teams. It also falls in line with the pattern of opening up technical work and knowledge across a broad set of roles and functions, it says.
“The best path forward for someone with traditional infrastructure management skills may be platform engineering,” Delory says. “A platform is an internal software product that abstracts away the underlying complexity of infrastructure and presents it to end users in whatever way best suits them.”
Platform engineers must be able to engage with internal users, understand their needs, and build products that are most useful to them, Delory says. “Infrastructure platform engineering allows you to take the deep knowledge you have about infrastructure and build it into something truly useful, a platform that enhances developer productivity and—ideally—your company’s bottom line.”
