New features in Red Hat Enterprise Linux (RHEL) are tuned to provide better remote support for edge networking where processor- and memory-constrained devices can present management problems. RHEL 8.4 announced this week at Red Hat Summit has new capability to send lighter-weight universal base images and is designed for potentially less capable edge devices, letting Red Hat customers deploy edge applications more flexibly. In addition to the new RHEL version, Red Hat announced updates to…

Big Blue kept its checkbook open this week buying AI-based application and network-performance management vendor Turbonomic for an unconfirmed estimate of $2 billion. The acquisition is the eleventh hybrid-cloud and AI-focused buy since Arvind Krishna became IBM CEO in 2020. “Hybrid cloud and AI are the two dominant forces driving change for our clients and must have the maniacal focus of the entire company,” he said at that time. The Economic Times and Reuters said…

20 years ago, I used to work as a network engineer for a fast-growing company that had multiple data centers and many remote offices, and I remember all the work required to simply onboard a remote site. Basically, it took months of planning and execution which included ordering circuits, getting connectivity up and spending hours, and sometimes days, deploying complex configurations to secure the connectivity by establishing encrypted tunnels and steering the right traffic across…

By Alice Pollard, Innovation Program Manager, Cisco Customer Experience, Chief Technology Office & Marisol Palmero, Technical Lead, Cisco Customer Experience, Chief Technology Office      Social distancing, masks, and pandemic are terms that have become all too familiar to us today. But back in early 2020, we had no idea how those words would flip the way we work, innovate, and collaborate with one another. Learning to “pivot” became part of our everyday vocabulary. At…

Data lies at the heart of all security operations. Like other networking operations, security relies on the ability to trust the data. Data pools that are outdated, duplicated, or overwhelming can impact the security operations (SecOps) team’s ability to perform analysis and develop policies. Intrusions can go undetected. Malware can spread. Assets may be compromised, and infections may go without remediation. To address this, SecOps must leverage systems to view this data accurately and in…

In celebration of International Women’s Day on March 8, we reached out to a group of women security experts and asked them, “Who has meant the most to you as an ally? And how has this impacted your career?” We then compiled their answers into an e-Book, Lifting Each Other Up: A Celebration of Women in Cybersecurity and Their Advocates.  This resource illuminates how some of today’s leading infosec women experts got started in the…

How do you know #LoveWhereYouWork is more than a saying? For me, there’s lots of reasons – but less than three weeks before the arrival of my firstborn, my team in Customer Experience showed that in a way unlike any other. During an all hands meeting, it was announced that a member of our leadership was at someone’s door with a surprise. Everyone was shocked, and immediately the team’s expressions shifted as a few asked,…

The COVID-19 pandemic exposed gaps in enterprise disaster recovery and business continuity planning in areas such as remote access, networking, SaaS applications and ransomware. Over the past year, IT execs have been scrambling to plug those gaps and update DR plans on the fly. More significantly, the pandemic triggered fundamental IT changes at many organizations, including a hasty migration of applications to the cloud, an acceleration of digital transformation efforts, the emergency provisioning of new systems…
