Top enterprise data center trends you need to know

Data-center networking was already changing prior to the technology challenges brought on by the COVID-19 pandemic, and few areas of the enterprise will continue to be affected more than data centers by those modifications in the future.That’s because myriad technologies are driving changes in the data center—everything from heavy demand for higher-speed networking, support for a remote workforce, increased security, tighter management and perhaps the biggest alteration—the prolific growth of cloud services.To read this article in full, please click here READ MORE HERE…

How COVID-19 is shaping enterprise networking

The COVID-19 pandemic has influenced the networking arena in a number of ways, including the rise of fully automated remote offices, the need to support a “branch of one,” and the growth of new communications software tools.”One of the biggest trends we are seeing is business agility. That is, IT looking at the tech they have deployed and evaluating it not just in terms of speeds and feeds, but how agile it is to handle whatever’s coming next,” said Todd Nightingale, Cisco’s Enterprise Networking & Cloud business chief. “Software APIs are a huge part of that trend, because it is amazingly easier to handle changes through APIs and software that make it possible to change things in a day rather than months.”To read this article in full, please click here READ MORE HERE…

Arista embraces segmentation as part of its zero-trust security

Arista has expanded its security software to let customers control authorized network access and communication between groups from the data center to the cloud.The new software, Macro-Segmentation Service (MSS)-Group, expands the company’s MSS security-software family, which currently includes MSS Firewall for setting security policies across customer edge, data-center and campus networks. Additionally, the company’s MSS Host focuses on data-center security policies.See how AI can boost data-center availability and efficiency
MSS software works with Arista Extensible Operating System (EOS) and its overarching CloudVision management software to provide network-wide visibility, orchestration, provisioning and telemetry across the data center and campus. CloudVision’s network information can be utilized by Arista networking partners including VMware, Microsoft and IBM’s Red Hat.To read this article in full, please click here READ MORE HERE…

How to enforce password complexity on Linux

Deploying password-quality checking on your Debian-based Linux servers can help ensure that your users assign reasonably secure passwords to their accounts, but the settings themselves can be a bit misleading.For example, setting a minimum password length of 12 characters does not necessarily mean that all your users’ passwords will actually have 12 or more characters.Let’s stroll down Complexity Boulevard and see how the settings work and examine some that are worth considering.[Get regularly scheduled insights by signing up for Network World newsletters.]

VMware plan disaggregates servers; offloads network virtualization and security

VMware is continuing its effort to remake the data center, cloud and edge to handle the distributed workloads and applications of the future.At its virtual VMworld 2020 event the company previewed a new architecture called Project Monterey that goes a long way toward melding bare-metal servers, graphics processing units (GPUs), field programmable gate arrays (FPGAs), network interface cards (NICs) and security into a large-scale virtualized environment.Monterey would extend VMware Cloud Foundation (VCF), which today integrates the company’s vShphere virtualization, vSAN storage, NSX networking and vRealize cloud management systems to support GPUs, FPGAs and NICs into a single platform that can be deployed on-premises or in a public cloud.To read this article in full, please click here READ MORE HERE…

What is SASE? A cloud service that marries SD-WAN with security

Secure access service edge (SASE) is a network architecture that rolls software-defined wide area networking (SD-WAN) and security into a cloud service that promises simplified WAN deployment, improved efficiency and security, and to provide appropriate bandwidth per application.Because it’s a cloud service, SASE (pronounced “sassy”) can be readily scaled up and scaled down and billed based on usage. As a result, it can be an attractive option in a time of rapid change.[Get regularly scheduled insights by signing up for Network World newsletters.]
While some vendors in this space offer hardware devices to connect at-home employees and corporate data centers to their SASE networks, most vendors handle the connections through software clients or virtual appliances.To read this article in full, please click here READ MORE HERE…

Coronavirus challenges remote networking

As the coronavirus spreads, many companies are requiring employees to work from home, putting unanticipated stress on remote networking technologies and causing bandwidth and security concerns.Businesses have facilitated brisk growth of teleworkers over the past decades to an estimated 4 million-plus. The meteoric rise in new remote users expected to come online as a result of the novel coronavirus calls for stepped-up capacity.Research by VPN vendor Atlas shows that VPN usage in the U.S. grew by 53% between March 9 and 15, and it could grow faster. VPN usage in Italy, where the virus outbreak is about two weeks ahead of the U.S., increased by 112% during the last week. “We estimate that VPN usage in the U.S. could increase over 150% by the end of the month,” said Rachel Welch, chief operating officer of Atlas VPN, in a statement.To read this article in full, please click here READ MORE HERE…
