Choose flexible edge deployments carefully

Many edge-computing deployments are driven by very specific needs, but since new needs may arise down the road with a different set of edge requirements, IT leaders should adopt edge-computing architectures with flexibility and adaptability in mind.The fact that all edge-computing systems have certain things in common – complex combinations of hardware, applications, infrastructure software and networking – doesn’t mean they should all have the same design.[Get regularly scheduled insights by signing up for Network World newsletters.] Every new project requires highly specialized software and integrated custom networking to deliver on project goals across such diverse applications as industrial control, autonomous transportation, health services, public safety and energy management. Each use case will have its unique requirements in terms of performance, response times, quantity of data to be gathered and processed, and cost.To read this article in full, please click here

Remote access needs strategic planning right now

The future of remote work has arrived.With the work-at-home mandates triggered by COVID-19 quarantines, businesses have adapted on-the-fly to create remote-networking environments that maintain corporate security. Largely, they have done so by expanding traditional remote access solutions including VPN infrastructure and services, virtual desktop infrastructure, secure Wi-Fi access points and even SD-WAN for home use.To read this article in full, please click here

Game changers at the branch: Wi-Fi 6, 4G, 5G plus SD-WAN

Combining 4G and 5G cellular services with SD-WAN can give enterprise IT pros connectivity options that are faster than wired alternatives such as MPLS and that provide benefits including rapid provisioning, improved reliability and more bandwidth for less money.Branch offices, which are undergoing dramatic changes in the amount of traffic they generate and where that traffic goes, can particularly benefit from 4G and 5G, and one enabler is software-defined WAN.To read this article in full, please click here

IT pros need to weigh in on that ‘sassy’ security model

Cloud services that provide both network and security intelligence are gaining popularity because they are easy to consume and they improve agility. Similarly, a model known as SD-Branch is providing network and security functionality at the WAN edge on a single platform.Both of these trends have contributed to the development by Gartner of a network architecture known as the secure-access service edge or SASE, which “converges network (for example, software-defined WAN) and network security services (such as [secure web gateways], [cloud access security brokers] and firewall as a service).” SASE (pronounced “sassy”) would primarily be delivered as a cloud-based service, Gartner says.To read this article in full, please click here

SD-WAN in 2020: 6 trends to look for

The market for SD-WAN remains white hot with distributed organizations widely deploying the technology to solve WAN bandwidth limitations, provide reliability/resiliency and improve quality of user experience for cloud-based applications.Dozens of suppliers are rapidly innovating and maturing their SD-WAN products with innovations in cloud onramps, support for leading SaaS applications, security and management/automation platforms.[Get regularly scheduled insights by signing up for Network World newsletters.] Here are six top issues to evaluate as SD-WAN moves to its 2.0 phase and beyond during 2020.To read this article in full, please click here

White-box switches yield initial savings but pose challenges

Despite the clear cost benefits, white-box switches outfitted with independent network operating systems (NOS) solutions have seen only limited adoption in leading enterprise IT shops.  That’s due to the lack of a clear market leader, implementation challenges and concerns about service and support that have steered IT pros toward traditional, branded-box Ethernet switches instead.[Get regularly scheduled insights by signing up for Network World newsletters.] But maturing technology and new support alliances are making white-box switches an attractive alternative for greenfield deployments and for infrastructure that’s being upgraded to give performance boosts to data centers, campuses and branch offices.To read this article in full, please click here

Tight Wi-Fi integration is key to successful SD-Branch

The promise of SD-Branch is that by collapsing network functionality in branch offices to a unified platform, enterprises can reap benefits in speed of deployment, ease of operation and cost. Since Wi-Fi is a critical piece of local area communications for many branch sites, improved integration, security and management of Wi-Fi is becoming increasingly important to evaluating the benefits of SD-Branch solutions.In branch offices, connected LAN devices and applications must be linked to the Internet via SD-WAN services. By integrating LAN and WAN connectivity, SD-WAN helps to simplify network management with a unified platform as compared to each function having its own unique management console.To read this article in full, please click here

When private 4G LTE is better than Wi-Fi

While cellular wireless is often thought of as a carrier service, IT organizations can benefit from deploying private 4G LTE technology to complement or even replace Wi-Fi and for specific use cases such as supporting IoT devices that generate large data sets and that are spread out over large areas.To read this article in full, please click here(Insider Story)

When to use 5G, when to use Wi-Fi 6

We have seen hype about whether 5G cellular or Wi-Fi 6 will win in the enterprise, but the reality is that the two are largely complementary with an overlap for some use cases, which will make for an interesting competitive environment through the early 2020s.The potential for 5G in enterprises The promise of 5G for enterprise users is higher speed connectivity with lower latency. Cellular technology uses licensed spectrum which largely eliminates potential interference that may occur with unlicensed Wi-Fi spectrum.  Like current 4G LTE technologies, 5G can be supplied by cellular wireless carriers or built as a private network . To read this article in full, please click here
