The Multicloud We Need, But Not the One We Deserve

Large organizations are married to the VMware suite of products. We can quibble about numbers for adoption of Hyper-V and KVM, but VMware dominates the enterprise virtualization market, just as Kubernetes is the unquestioned champion of containers.

Virtual Machines (VMs) are a mature technology, created and refined before large-scale adoption of public cloud services. Cloud-native workloads are often designed for containers, and containerized workloads are designed to fail. You can tear one down on one cloud, and reinstantiate it on another. Near-instant reinastantiation is the defense against downtime.

VMs take a different approach. A VM is meant to keep existing for long periods of time, despite migrations and outages. Failure is to be avoided as much as possible. This presents a problem as more organizations pursue a multi-cloud IT strategy.

The key technology for highly available VMs is vMotion: the ability to move a VM from one node in a cluster to another with no downtime. However, as data centers themselves become increasingly virtualized, using cloud computing services such as Microsoft Azure, Google Compute Engine, and Amazon EC2, there’s a growing requirement to be able to move VMs between cloud infrastructures. This is not a supported feature of vMotion.

Interview with Joe Onisick

With this blog, I try to inspire and mentor. One person I have a lot of respect for is Joe Onisick. I had the pleasure of interviewing Joe. Joe has really transformed himself and everything about him lately and I thought it would be nice to give you readers some more insight to his journey. Here is Joe’s story:

Q: Hi Joe, welcome to the blog! Please give the readers a short introduction of yourself.

A: I’m a technology executive who’s been in the field for 23 years, with the exception of a five-year break to serve as a US Marine. I started in network/email administration and have spent most of my career in the data center space on all aspects of delivering data center resources, up to IaaS and private-cloud.

Q: Many people probably know you best from your time at Cisco, working for the Insieme BU, responsible for coming up with ACI. What was your time at Cisco like? How were you as a person at that time?

A: I joined a startup called Insieme Networks that was in the early stages of developing what became Cisco ACI and Nexus 9000. When the product was ready to launch, Continue reading

IDG Contributor Network: Software-defined perimeter: Identity-centric enforced network perimeter

With the introduction of cloud, BYOD, IoT and virtual offices scattered around the globe, the traditional architectures not only hold us back in terms of productivity but also create security flaws that leave gaps for compromise.The network and security architectures that are commonly deployed today are not fit for today's digital world. They were designed for another time, a time of the past. This could sound daunting...and it indeed is.What we had in the past? Traditionally, we have had a static network and security perimeter with clear network and security demarcation points. In terms of security, the perimeter-based approach never worked. It did, however, create a multi-billion-dollar industry. But the fact is, it neither did, not will it provide competent security.To read this article in full, please click here

BrandPost: Deploying highly secure, easy to deploy and cost-effective Micro Data Centers

Industry trends such as the Internet of Things (IoT) and content distribution networks (CDNs) are driving the need for edge computing. That’s because these solutions often require low latency, high bandwidth, greater reliability, and strong security.It’s a tall order meant for Micro Data Centers (MDCs) to fulfill. An MDC is a self-contained data center architecture that offers complete IT infrastructure within a stand-alone, secure enclosure.MDCs offer a number of key advantages beyond today’s server rooms and traditional data centers. First, because they’re distributed closer to bandwidth-intensive content, MDCs can significantly reduce latency and lower costs. Secondly, it’s easy and cost-effective to add data center capacity to them anywhere and anytime it is needed – in both IT room and non-climate-controlled environments. And because MDC IT equipment is pre-installed before shipment in a self-contained and secure enclosure, it can provide physical security and protection of critical business applications.To read this article in full, please click here

DoE plans world’s fastest supercomputer

The U.S. Department of Energy says it is working on a supercomputer that will break the target of exaFLOP computation – a quintillion (1018)  floating-point computations per second – in order to handle high-performance computing and artificial intelligence.Being built in conjunction with Intel and Cray Computing,  the Aurora supercomputer will  cost more than half a billion dollars and be turned over to Argonne National Laboratory in Chicago in 2021, according to a statement by the DoE.

Concluding the IETF Rough Guide, Long Live the IETF Blog

For many years we have produced a series of blog posts as a Rough Guide to each upcoming IETF meeting usually in the week prior to the meeting. The Rough Guides were intended to provide a snapshot of IETF activity of interest to the Internet Society because of programmatic activity that we were engaged in. They were also an opportunity to highlight the activities sponsored directly by the Internet Society that were happening adjacent to the upcoming IETF meeting.

Rough Guides were intended to help guide a non-specialist but technically minded audience to the hot topics and debates of interest at each upcoming IETF meeting with pointers to the agenda and remote participation possibilties. Originally intended to help spur meeting attendance by those interested in the key topics, they became a way to highlight important discussions taking place and ways to get involved in person or remotely.

As we are now less than a week away from the IETF 104 meeting in Prague it seemed like the right time to share an update regarding our plans for writing about IETF activity. We have decided to discontinue producing the Rough Guides. Instead, we will be helping to supply relevant, high-quality content Continue reading

3 companies developing wearable tech for the enterprise

Earlier this month, I wrote that “even as smartwatch shipments continue to grow, significant industrial and business use cases for these internet-connected devices have yet to appear.”And then a few days later, as if on cue, International Data Corporation (IDC) put out a press release about the latest edition of the Worldwide Quarterly Wearable Device Tracker. The release quoted Ramon T. Llamas, research director for IDC's Wearables team, saying, "Two major drivers for the wearables market are healthcare and enterprise adoption.”To read this article in full, please click here

Automating Cisco ACI Environment with Python and Ansible

This is a guest blog post by Dave Crown, Lead Data Center Engineer at the State of Delaware. He can be found automating things when he's not in meetings or fighting technical debt.

Over the course of the last year or so, I’ve been working on building a solution to deploy and manage Cisco’s ACI using Ansible and Git, with Python to spackle in cracks. The goal I started with was to take the plain-text description of our network from a Git server, pull in any requirements, and use the solution to configure the fabric, and lastly, update our IPAM, Netbox. All this without using the GUI or CLI to make changes. Most importantly, I want to run it with a simple invocation so that others can run it and it could be moved into Ansible Tower when ready.

BrandPost: SD-WAN Without WAN Optimization is Like Peanut Butter Without Jelly

SD-WAN vs. WAN Optimization Optimization of applications and data traffic has been an integral part of the WAN since its inception. WAN optimization accelerates application traffic by overcoming latency and reducing the amount of data traversing the WAN by applying techniques like protocol acceleration, deduplication, compression, reduced latency and caching to dramatically increase the amount of available bandwidth.Today, enterprises are rapidly adopting SD-WAN as a preferred solution when rearchitecting their WANs. SD-WAN is transforming the way networks support enterprise applications, dramatically increasing application performance by intelligently controlling and more efficiently utilizing all available WAN transport resources.To read this article in full, please click here
