The late science fiction author Ray Bradbury’s short story classic“Jurassic Park”film franchise by decades, the follies of technology innovation that allow, among other things, for humans to interact with dinosaurs, predictably goes awry. However, “A Sound of Thunder”’s main theme is not so much about the risks of appeasing humans’ archetypical curiosity about scary beasts as it is about how interconnected our actions are. Bradbury portrays, for example, how the mere accident of going back in time and stepping on a butterfly can set in motion a chain of reaction that eventually leads to cataclysmic events in the future.

In today’s IT world of distributed systems built with Kubernetes and container orchestration technologies, it is beginning to emerge just how deep applications really are, as well as how deeply distributed they are. One of the effects this very distributed and connected infrastructure has is reflected in the famous
VMware has been on a buying jag in the past year, and its latest planned acquisition is the Palo Alto, Calif.-based Sanjay Uppal said in the acquisition announcement.
CEO and co-founder blog post:
First, Nyansa can proactively predict client problems, optimize their network, better enable the behavior of critical IoT devices, and justify infrastructure changes based on actual user, network and application data. Second, you will be able to use the breadth and depth of Nyansa’s data ingestion and analysis, including packet analysis and metrics via API across multivendor wired and wireless LAN environments. Finally, the combination of Nyansa’s AI/ML capabilities with VMware’s existing analytics, visibility and remediation capabilities will make it easier for you to operate and troubleshoot the virtual cloud network and accelerate the realization of a self-healing network.
Nyansa was valued at around $65 million after its most recent funding two years ago and had raised about $26.5 million, Carbon Black.
The transaction is expected to close within the next few months, subject to customary closing conditions.

Chris Wade serves as the co-founder and CTO of Itential, a network automation software company focused on simplifying and accelerating the adoption of network automation and transforming network operations practices.
There has been tremendous innovation in IT infrastructure with the adoption of cloud-scale architecture and a migration towards modern applications. In contrast, Enterprise networking has been viewed over the last 30 years primarily for moving data between client-server applications. This basic premise along with consumer devices drove innovation in the network domain to prioritize “speeds and feeds” as the primary objective for networking vendors. Even with the adoption of cloud-scale infrastructure, most adoption meant a migration from current data centers to cloud platforms for IaaS (Infrastructure as a Service) which didn’t dramatically impact networking requirements.
For some context on network innovation, it is important to break network devices into their logical components. A simplified view of networks separates general functionality into three primary components:
Data Plane — Movement of packets or network data between network elements
Control Plane — Decision logic of where to send network data on the data plane
Management Plane — Interfaces that allow users & external systems to modify the behavior of the network.
In this latest The New Stack Makers podcast recorded live at Zachary Smith, CEO and co-founder of Packet, and Sprint, discussed how bare metal fits into the emerging Internet of Things. The Dec. 4-5 event was Packet’s second annual vendor-neutral infrastructure conference and ran at the same time as AW Re:Invent.
A metaphor Rook used to describe bare-metal deployments for Sprint, a Packet customer, came from his daughter who had to tell her grade school class what her father did for a living: she said her father was a “machine whisperer.”

The metaphor fits well because it aptly reflects what bare-metal machines “try to tell you,” Rook said. “An individual machine cannot tell you much, but what machines tell you only start to make sense when you do two things: Number one is you start to listen to all of them at same time, and number two is you start to learn what they tell Continue reading
Consul services networking platform with the capability to manage service namespaces at an organization-wide level.
Released Tuesday, Consul 1.7 also comes with additional plugins to support a number of application monitoring and management tools, including AppDynamics, Datadog and the NGINX proxy.
HashiCorp presents Consul as a network automation tool for enterprises to connect and secure application services across multiple clouds and on-prem environments, putting all the services on a single communication plane with a shared registry.
The thinking behind Consul is that “you need a namespace service registry for the new, dynamic environment,” noted
on the HashiCorp blog.

As NGINX, it has pledged published in the second half of 2018 found NGINX to be the most widely used ingress provider for Kubernetes.
For the Seattle-based application controller delivery software provider, a $670 million acquisition provides an established user base and mature technology that puts it at the center of microservice architectures.
Earlier this year, when it purchased NGINX, F5 said it planned to augment the open source web server/load balancer and reverse proxy software with F5’s own security technologies as well as with a set of “cloud native innovations” to enhance load balancing.
At François Locoh-Donou, president and CEO of F5 Networks pointed out that the technology acquisitions that have paid off for customers have been those in which the acquired company’s technology was core to the strategy of the acquiring company.
“NGINX is core to the strategy of F5 Networks,” he said. “Combined with the reach and breadth of the F5 application security portfolio, we Continue reading
Developers tend to pay less attention to the underlying bare metal infrastructure supporting their open stack deployments. This is understandable amid the explosion of available open source tools and platforms on the cloud. But as the dust settles and organizations seek more ways to improve application performance, bare metal servers and devices are emerging as a key differentiator among DevOps teams looking for any way to improve application performance, and ultimately, the user experience. The issue, for many developer teams, is thus how to have control over the entire stack which, again, covers the bare metal infrastructure as well.
Packet has built its business around provisioning infrastructure for on-premises and the cloud, software that boosts server and overall ecosystem performance is critical as well — and for a number of reasons, open source alternatives play an obvious key role in what Packet does.
While Packet has contributed the open source community largely by providing servers and infrastructure for development purposes to projects such as the CNCF and CI/CD platform Nathan Goulding, chief architect for Continue reading
KubeCon + CloudNativeCon North America 2019, Nov. 18-21 in San Diego.
Perhaps the most global use case to come for Kubernetes is in the telecommunications industry. It does have about five billion users after all. And it’s inherently a hardware-backed, well-regulated industry.
The New Stack founder and publisher Alex Williams sat down at last month’s KubeCon + CloudNativeCon to talk about telco’s cloud native future with OPNFV), and Vulk Coop design and development cooperative. The different collaborative, telecom-focused Linux Foundation and Cloud Native Computing Foundation working groups that Kirksey and Carpenter are a part of have witnessed — and sometimes driven — telco’s move over the last five years from monolithic hardware appliances toward what’s now known as the cloud.

Is it possible that managing stateful applications on Kubernetes will become easier than handling the stateless apps containers were originally designed for? Portworx, said that’s what customers are telling him.
When it comes to encouraging the adoption of Kubernetes in production in an enterprise setting, that is good news, but not something everyone would agree with. In a recent poll by The New Stack, 10% of respondents thought that improving Kubernetes’ integration with storage was the top challenge for the community — after concerns about user experience and support for multitenancy.
But Thirumale isn’t the only one who thinks the Kubernetes ecosystem is ready for stateful workloads. “People are starting to do serious stateful workloads in the cloud and in Kubernetes, in particular,” SoundCloud | Pocket Casts | Apple Podcasts | Spotify |

While you may thinking of Kubernetes as the future of computing, but it was, until recently, still stuck in the past in one way, namely that it was built on IPv4, the widely-used, though a soon-to-be-legacy version of the Internet Protocol upon which the internet was built.
The Internet Engineering Task Force has been long urging the internet service providers to move to IPv6, now that the world has exhausted the supply of 32-bit IPv4 addresses. With its 128-bit address space, IPv6 will offer an inexhaustibly supply of internet addresses.

Business today moves at the speed of 1s and 0s, flashing through the internet into our computers, mobile phones, tablets and smart speakers. Digital Transformation is an undeniable driving force behind business success, and organizations that can’t adapt to the needs of their customers and the demands of their industry will get left behind. It has been eons (in internet terms) since just having a website was enough to be competitive. If your organization has mastered SEO, incorporated server virtualization, adapted to today’s mobile-first mentality — for both employees and customers — and are looking at the next step you can take to compete, SD-WAN is the next logical step.
SD-WAN (software-defined wide area network) at first glance appears to be an almost impossible chimera of “cheaper, faster and better” at Continue reading
Application delivery controller provider Project Nova, a cloud native, hosted ADC service that is managed from a browser.
Nova is a response to customers using their existing ADC device in a manner that was never intended, Snapt CEO request access, with a community edition providing free access for up to five deployed nodes. At launch, Project Nova provides support for native service discovery on Kubernetes, Docker, Rancher, Consul and more, as well as full-automation with a REST API.
Blakey says they expect Project Nova’s beta to be available by mid-November and a full integration with service meshes by mid-December, with ” the real idea to be this app delivery fabric, which just takes responsibility for the delivery of your app across whatever infrastructure you’re running in.” General availability, he says, is expected by early 2020.

In the race to keep up with swiftly moving digital currents, enterprises are in search of ways to automate their networks. They want to remove complexity and make changes to their networks quickly and effectively. Vendors are offering a variety of scripting approaches to network management that are open-source. The use of scripts in DevOps has been effective since they are generally run on consistent operating systems and compute platforms.
The industry is now trying to push scripting on NetOps, but it is much harder due to the variation of vendors, operating systems and hardware platforms used in the networking layer. Scripts may provide a quick fix, but they are not reliable over time and not a long-term strategic solution. In addition, these approaches may be risky, as they could lead to costly errors and network outages.

Virtual networking softwareKubernetes open source container orchestration software. While Kubernetes has extensive support for Role-Based Access Control (RBAC), the default networking stack based on Google Kubernetes Engine (GKE). Unlike other managed Kubernetes services, GKE comes with an integrated Calico stack that can be enabled during the cluster creation. It is also possible to configure Calico on an existing, running GKE cluster.
Start by launching a standard GKE cluster with network policies enabled. This can be done by clicking the Enable network policy checkbox available under Availability, networking, security, and additional features section.
After the cluster is up and running, we can check for Calico Pods deployed as a part of Daemonset in the kube-system namespace. Let’s download the calicoctl, Calico’s CLI to explore the environment further. We need to point calicoctl to etcd endpoints of GKE cluster. This can be done with the below settings:
Now, let’s go ahead and deploy one of the samples provided by Project Calico. Run the below commands to deploy the application. You can download the YAML files from Project Calico’s http://mi2.live.
