Come See Pica8 at Dell Technologies World – and Help Save a Real-Life Pika

Having been around the block a time or two, I’ve seen my share of trade show event booth giveaways and all manner of tchotchkes, most of which find their way to a trash can before the visitor gets home. For the upcomingDell Technologies World 2019in Las Vegas, we wanted to do something different – something that would impact the world in a positive way.

So, we’ll be raffling off 100 “adoptions” of real North American pikas, as part of the National Wildlife Federation’s Adopt-a-Pika program.

A pika is a small mammal, closely related to rabbits – and it’s in trouble. As the NWF explains, “Pikas live in high mountain ecosystems that are cool and moist. Higher temperatures can cause the pikas to overheat.”

As global warming brings higher temperatures to the pika’s habitat, it’s creating real problems. Pikas can’t just go find higher ground where it’s cooler – because that higher ground is their natural habitat.

“Without our protection and help, American pikas could be the first species with the distinction of going extinct due to global warming,” the NWF says.

To avoid that distinction, the NWF launched the “Adopt an Continue reading

Day Two Cloud 007: Digital Transformation Is More Than Just Cloud Migration

Pushing your heritage application to the cloud won't digitally transform your company any more that slapping an Autobots symbol on your car makes it a Transformer. On today's Day Two Cloud podcast, guest Martin Ehrnst delves into the nuances of digital transformation in the enterprise.

BrandPost: Clearing up confusion between edge and cloud

Edge computing and cloud computing are sometimes discussed as if they’re mutually exclusive approaches to network infrastructure. While they may function in different ways, utilizing one does not preclude the use of the other.Indeed, Futurum Research found that, among companies that have deployed edge projects, only 15% intend to separate these efforts from their cloud computing initiatives — largely for security or compartmentalization reasons.So then, what’s the difference, and how do edge and cloud work together?Location, location, locationTo read this article in full, please click here

Distributed Firewall on VMware Cloud on AWS

This blog post will provide a deep dive on the distributed firewall (DFW) on VMware Cloud on AWS (VMC on AWS). Let’s start with the basic concepts of a distributed firewall:

Distributed Firewall Concepts

The distributed firewall is an essential feature of NSX Data Center and essentially provides the ability to wrap virtual machines around a virtual firewall.

The virtual firewall is a stateful Layer 4 (L4) firewall – it’s capable of inspecting the traffic up to the Layer 4 of the OSI model: in simple terms, it means they look at IP addresses (source and destination) and TCP/UDP ports and filter the traffic based upon these criteria.

What’s unique about our firewall is that it has contextual view of the virtual data center – this means our distributed firewall can secure workloads based on VM criteria instead of just source and destination IP addresses.

Traditional firewalling is based on source and destination IPs – constructs that have no business logic or context into applications. Our distributed firewall can secure workloads based on smarter criteria such as the name of the virtual machine or metadata such as tags.

This enables us to build security rules based on business logic (using Continue reading

Applications Open: Training for New Chapter Leaders in Latin America and the Caribbean

For us at the Internet Society, the role that people play in our community is vital to carrying our message in favor of an open and trusted Internet for all. We rely on the contributions, knowledge, and experience of our members. For this reason, the Chapters of the Latin American and Caribbean region have come together to offer and implement a pilot training program for their members.

Active participation of people in their local chapter is one of the main objectives of the program. The people involved will contribute to the four focus areas of the Internet Society’s 2019 Action Plan and will adopt our narrative and tone of voice. The sessions of the program will have facilitators from the LAC region with extensive knowledge on the topics addressed. In addition there will be special sessions with participation of experts from Internet Society staff.

180 seats are available to be distributed among Chapters of the LAC region. The selected candidates will have the opportunity to be trained in Internet Governance; community networks and access; Internet technical security; or the Internet of Things and Public Policy. The general criteria for participating is published here, although it is important to emphasize Continue reading

Startup MemVerge combines DRAM and Optane into massive memory pool

A startup called MemVerge has announced software to combine regular DRAM with Intel’s Optane DIMM persistent memory into a single clustered storage pool and without requiring any changes to applications.MemVerge has been working with Intel in developing this new hardware platform for close to two years. It offers what it calls a Memory-Converged Infrastructure (MCI) to allow existing apps to use Optane DC persistent memory. It's architected to integrate seamlessly with existing applications.[ Read also: Mass data fragmentation requires a storage rethink ] Optane memory is designed to sit between high-speed memory and solid-state drives (SSDs) and acts as a cache for the SSD, since it has speed comparable to DRAM but SSD persistence. With Intel’s new Xeon Scalable processors, this can make up to 4.5TB of memory available to a processor.To read this article in full, please click here

Decide How Badly You Want to Fail

Every time I’m running a data center-related workshop I inevitably get pulled into stretched VLAN and stretched clusters discussion. While I always tell the attendees what the right way of doing this is, and explain the challenges of stretched VLANs from all perspectives (application, database, storage, routing, and broadcast domains) the sad truth is that sometimes there’s nothing you can do.

You’ll find a generic version of that explanation in Building Active-Active and Disaster Recovery Data Centers webinar. Every few months I might be available for an onsite version of that same discussion, or you could engage one of the other ExpertExpress consultants.

In those sad cases, I can give the workshop attendees only one advice: face the reality, and figure out how badly you might fail. It’s useless pretending that you won’t get into a split-brain scenario - redundant equipment just makes it less likely unless you over-complicated it in which case adding redundancy reduces availability. It’s also useless pretending you won’t be facing a forwarding loop.
