How to buy enterprise firewalls

Enterprise firewalls have been the quintessential security device for decades, standing guard at the perimeter, inspecting all inbound and outbound traffic for malware. So, what happens to firewalls as the perimeter fades away? They evolve.To read this article in full, please click here(Insider Story)

5 steps for modernizing enterprise networks

The business value of the network has never been higher, and this is driven by digital transformation as borne out businesses accelerating their digital initiatives by as much as seven years due to the pandemic. This is had a profound impact on the enterprise network as most of the enabling technologies such as cloud, mobility and IoT are network centric.This intense focus on digital transformation has exposed many flaws with legacy networks. They are rigid, require intensive manual processes, and lack the agility and intelligence to meet the demands of digital business. Organizations need to make network modernization a priority if they are to maximize their investments in other technologies. Here are five steps that all businesses should consider when modernizing the network.To read this article in full, please click here

Is SD-WAN out to kill MPLS?

There is arguably no networking technology surrounded by more hype than software defined WANs (SD-WAN), and much of it is well deserved. SD-WAN resources What is SD-WAN and what does it mean for networking, security, cloud? 10 SD-WAN features you’re probably not using but should be SD-WAN may be the key to smart network services SD-WAN and analytics: A marriage made for the new normal Native SD-WAN monitoring tools are not enough, survey says A significant number of network professionals either have an SD-WAN deployment underway or on their near-term roadmap. The reason is that SD-WAN architecture is optimized for cloud computing while legacy WANs were designed when client-server computing was the norm.To read this article in full, please click here

Next-gen wireless options: Wi-Fi 6, 5G or private 5G?

One of the great debates in networking has been whether to use wired connectivity—which brings speed—or wireless—which delivers mobility. Recent versions of Wi-Fi deliver speeds comparable to wired, removing this debate. Wired connections are still faster, but for most user applications, including video, there is no experience difference. Looking ahead, next-generation wireless will be well North of 1Gbps, making it a no-brainer to use wireless.The next big decision: What kind of wireless?In the past, there was only one option, and that was Wi-Fi. Now there is another option coming into play, and that’s 5G. Not 5G like the kind one has attached to your mobile phone, but private 5G used within enterprise environments.To read this article in full, please click here

How the data-center workforce is evolving

The COVID-19 pandemic has profoundly affected many areas of IT, including the data center, where changes to the infrastructure--particularly adoption of cloud services--are bringing about the need for new skill sets among workers who staff them. Tech Spotlight: The Future of Work Remote work 2.0 — when WFH really means 'work from anywhere' (Computerworld) 7 key questions facing the future of work (CIO) 6 top security technologies to protect remote workers (CSO) 7 best practices for remote development teams (InfoWorld) How the data center workforce is evolving (Network World) Perhaps no technology industry benefitted more from the pandemic than cloud computing; the location independence of cloud services makes them ideal for a world where the majority of line-of-business as well as IT workers are no longer in the office.To read this article in full, please click here

Wi-Fi 6E: When it’s coming and what it’s good for

This spring the FCC opened up a new swath of unlicensed wireless spectrum in the 6GHz band that’s intended for use with Wi-Fi and can provide lower latency and faster data rates. The new spectrum also has a shorter range and supports more channels than bands that were already dedicated to Wi-Fi, making it suitable for deployment in high-density areas like stadiums.To read this article in full, please click here(Insider Story)

SD-WAN needs a dose of AIOps to deliver automation

Software-defined WAN (SD-WAN) is getting a big boost from AIOps as vendors look to simplify operations, lower costs, and optimize WAN performance in the modern cloud era.SD-WAN decouples the control aspect of a network from the hardware to create a virtualized network overlay, while AIOps applies machine learning and data analytics to IT operations to automate processes. The convergence of the two – a.k.a. AI-driven WAN – promises to usher in a new era of WAN networking that enables IT to go beyond optimizing network and application experiences to delivering the best experiences to individual users. To read this article in full, please click here

What are data centers, and gow they are changing?

A data center is a physical facility that enterprises use to house their business-critical applications and information. As they evolve, it’s important to think long-term about how to maintain their reliability and security.What is a data center? Data centers are often referred to as a singular thing, but in actuality they are composed of a number of technical elements. These can be broken down into three categories: Compute: The memory and processing power to run the applications, generally provided by high-end servers Storage: Important enterprise data is generally housed in a data center, on media ranging from tape to solid-state drives, with multiple backups Networking: Interconnections between data center components and to the outside world, including routers, switches, application-delivery controllers, and more These are the components that IT needs to store and manage the most critical systems that are vital to the continuous operations of a company. Because of this, the reliability, efficiency, security and constant evolution of data centers are typically a top priority. Both software and hardware security measures are a must.To read this article in full, please click here
