What makes networking automation so difficult?

Ivan Pepelnjak asks the question most network engineers are already deliberating: Why is networking automation so hard?

In a post on IPSpace, Pepelnjak said the challenges facing automation — such as a lack of good tools and APIs — obscure the biggest reason networking automation is so tough to do. And that’s because, as Pepelnjak termed it, “every network is a unique snowflake.”

“You can buy dozens of network management products, download numerous open source tools, and yet you won’t be a single step closer to offering service-level abstraction of your network to your users,” he said.

A better approach might be to build a customizable tool to meet your needs, or to construct a network management system based on Ansible that’s integrated with an orchestration platform.

Or you could just give up, although Pepelnjak advises his readers to consider that decision very carefully before proceeding.

Could Fortnite justify 5G’s development?

Mobile carriers have been spending plenty of money constructing the frameworks necessary for 5G, the next generation of cellular technology. But telcos are still making these investments without knowing if there is a large enough business case to justify the sums they’re spending.

While many investors anticipate the enterprise networking market will be the first real use case for 5G, GlobalData analyst Josh Hewer has a better idea: gaming.

Gamers require connections with low latency and high availability, attributes that 5G connectivity offers, he said. Today, most players are harnessed to Wi-Fi networks, but that could change if higher-speed cellular is an option.

Epic Games, the developer of the smash hit Fortnite Battle Royale, is already pulling in $1 million a day from mobile users — illustrating how lucrative the market could be for 5G carriers.

“Operators are going to have to look outside of the enterprise market to justify early 5G investments,” Hewer said.

With one in three people on the planet paying for games on PC and mobile, according to Hewer, perhaps 5G investors should start to take gaming more seriously.

See the rest of Hewer’s thoughts on 5G and what carriers should consider.

Blockchain and its reliance on decentralization

According to Gartner analyst Rajesh Kandaswamy, it’s simply too early to tell how Blockchain will evolve and what its impact on networking will be.

Kandaswamy tackled two related questions: Is blockchain about decentralization? And can blockchain survive without decentralization?

Alas, a definitive answer is still not possible, Kandaswamy wrote, adding that it’s possible the ledger system can survive either way.

Regardless, he remained encouraged about the role blockchain may play in future networking environments. “Who are we to assume that the paths of future innovation will be restricted to certain ways, when the technology itself is evolving and humankind’s potential for ingenuity is vast?”

IDC, Cisco survey assesses future IT staffing needs

Network engineers, architects and administrators will be among the most critical job positions to fill if enterprises are to meet their digital transformation goals, according to an IDC survey tracking future IT staffing trends.

 The survey, sponsored by Cisco, zeroed in on the top 10 technology trends shaping IT hiring and 20 specific roles IT professionals should consider in terms of expanding their skills and training. IDC surveyed global IT hiring managers and examined an estimated 2 million IT job postings to assess current and future IT staffing needs.

The survey results showed digital transformation is increasing demand for skills in a number of key technology areas, driven by the growing number of network-connected devices, the adoption of cloud services and the rise in security threats.

Intersections provide hot jobs

IDC classified the intersections of where hot technologies and jobs meet as “significant IT opportunities” for current and future IT staffing, said Mark Leary, directing analyst at Cisco Services.

“From computing and networking resources to systems software resources, lots of the hot jobs function at these intersections and take advantage of automation, AI and machine learning.” Rather than eliminating IT staff jobs, a lot of jobs take advantage of those same technologies, he added.

Organizations are preparing for future IT staffing by filling vacant IT positions from within rather than hiring from outside the company, then sending staff to training, if needed, according to the survey.

But technology workers still should investigate where the biggest challenges exist and determine where they may be most valued, Leary said.

“Quite frankly, IT people have to have greater understanding of the business processes and of the innovation that’s going on within the lines of business and have much more of a customer focus.”

The internet of things illustrates the complexity of emerging digital systems. Any IoT implementation requires from 10 to 12 major technologies to come together successfully, and the IT organization is seen as the place where that expertise lies, Leary said.

IDC’s research found organizations place a high value on training and certifications. IDC found that 70% of IT leaders believe certifications are an indicator of a candidate’s qualifications and 82% of digital transformation executives believe certifications speed innovation and new ways to support the business.

Network influences future IT staffing

IDC’s results also reflect the changes going on within enterprise networking.

Digital transformation is raising the bar on networking staffs, specifically because it requires enterprises to focus on newer technologies, Leary said. The point of developing skills in network programming, for example, is to work with the capabilities of automation tools so they can access analytics and big data.

This isn’t something that’s evolutionary; it’s revolutionary.

In 2015, only one in 15 Cisco-certified workers viewed network programming as critical to his or her job. By 2017, the percentage rose to one in four. “This isn’t something that’s evolutionary; it’s revolutionary,” Leary said.

While the traditional measure of success was to make sure the network was up and running with 99.999% availability, that goal is being replaced by network readiness, Leary said. “Now you need to know if your network is ready to absorb new applications or that new video stream or those new customers we just let on the network.”

Leary is involved with making sure Cisco training and certifications are relevant and matched to jobs and organizational needs, he said. “We’ve been through a series of enhancements for the network programmability training we offer, and we continually add things to it,” he added. Cisco also monitors customers to make sure they’re learning about the right technologies and tools rather than just deploying technologies faster.

To meet the new networking demands, Cisco is changing its CCNA, CCNP and CCIE certifications in two different ways, Leary said. “We’ve developed a lot of new content that focuses on cybersecurity, network programming, cloud interactions and such because the person who is working in networking is doing that,” he said. The other emphasis is to make sure networking staff understands language of other groups like software developers.
