Nexthink’s digital experience management platform quickly solves performance problems

Any organization that has even a modest level of IT infrastructure does IT service monitoring (ITSM) to ensure that everything is operating within performance mandates codified in service level agreements (SLAs). If the IT organization is meeting its SLAs, it’s assumed that the experience the employee has interacting with this infrastructure is good. But that isn’t always the case, and the IT group might not even be aware.For instance, an enterprise application might be working just fine for most users, but for one or a few users in particular, it could be especially slow. Unless those people call the help desk to complain, who would ever know that they are suffering? Sometimes people just accept that some aspect of IT functions poorly, and they carry on the best they can, even if it affects their productivity.To read this article in full, please click here

NSX Cloud Blog Series Part 2: A Consistent Security Posture Across Your Hybrid Cloud

We now dig deeper into the cloud security use-case.  As more and more companies embrace cloud, the cloud IT teams are tasked with the responsibility of ensuring that these cloud deployments are secure. Cloud inherently brings in new environments, and these cloud security teams are now faced with ensuring Enterprise security policy consistency across these multiple disparate cloud environments.

 

VMware NSX Cloud addresses these challenges, offering a common security and micro-segmentation platform across the on-premises and cloud environment. Together with NSX Data Center, it provides a single pane of glass to provision and manages consistent security controls not only for cross-cloud communication but also within each cloud.

 

Let’s start with VISIBILITY. You can’t protect what you can’t see. As a cloud infrastructure/security team, you may have to manage 1 AWS cloud account (subscription in Azure) and 1 AWS VPC (VNET in Azure) … or you may be managing 500+ accounts/subscriptions, each having multiple VPCs / VNETs. As cloud deployments bring automation and higher levels of agility, the cloud footprint that you would be responsible for can quickly become large and constantly evolve. How do you ensure that this dynamic environment is secure?

Get ready for upcoming 6G wireless, too

Coinciding with a signing-off of global standardizations for the as-yet-unlaunched 5G radio technology by 3GPP this month we get news of initial development plans for faster 6G wireless. The Center for Converged TeraHertz Communications and Sensing (ComSenTer) says it’s investigating new radio technologies that will make up 6G.One hundred gigabits-per-second speeds will be streamed to 6G users with very low latency, the group says on its website.To read this article in full, please click here

BrandPost: Celebrating the Rise of 400G

Ciena Helen XenosSenior Director, Portfolio Marketing The era of 400G was in full force at OFC (The Optical Fiber Communication Conference and Exhibition), and we took some time to celebrate this milestone. Here are what our customers have to say about their 400G success – and what it means for the industry.If you needed another leading indicator that 400G is the next big thing in optical networks, look no further than the OFC ’18 conference recently held in San Diego.  The show was abuzz with vendor plans for new technologies that squeeze more bandwidth than ever down an optical channel.  These 400G-capable coherent solutions offer better system performance and tunable capacity from 100G to 400G per wavelength. To read this article in full, please click here

T-25 days until Chrome starts flagging HTTP sites as “Not Secure”

T-25 days until Chrome starts flagging HTTP sites as

Less than one month from today, on July 23, Google will start prominently labeling any site loaded in Chrome without HTTPS as "Not Secure".

When we wrote about Google’s plans back in February, the percent of sites loaded over HTTPS clocked in at 69.7%. Just one year prior to that only 52.5% of sites were loaded using SSL/TLS—the encryption protocol behind HTTPS—so tremendous progress has been made.

IDG Contributor Network: The ‘made up’ jargon of networking

Like any industry, networking has a proprietary slew of acronyms and jargon that only insiders understand. Look no further than Network World’s searchable glossary of wireless terms.Turns out, multiplexing has nothing to do with going to the movies at a place with more than one theater.I also like to think that each networker has their own favorite list of terms, ready to share at a moment’s notice during family dinners, holidays and networking events … or maybe that’s just me?To read this article in full, please click here

Techniques of a Network Detective: A New Series

Put your detective hat on your head and your Network Detective badge on your lapel.  Introducing a new blog series – Techniques of a Network Detective.  This series will focus on the detective work (troubleshooting side) of our jobs as network engineers.

For over 30 years I’ve been playing in the “world of IT”. During those years there have been a lot of changes in our world. But through all that change, there has been a thread, for me, that has always remained constant. A thread and a passion that always seemed to be with me in every job over all these years.

Troubleshooting!

Being a “Network Detective” is much the same as being a regular detective in many ways.  As a Network Detective we get put on a “case” – the “Case of the Missing Packets” maybe.  We go to the crime scene and try to find answers so we can solve the “who done it”

nd1

When a “crime” happens you need to be right there interviewing the suspects, surveying the crime scene, asking the right questions.  Trying to quickly figure out what is happening, where it is happening, and why it Continue reading
