Distributed Systems and the Butterfly Effect

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. Subscribe: | Stitcher | Overcast | TuneIn 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 Acquires Nyansa for AI-Aided Networking Analytics

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.

DENT: An Operating System for Disaggregated Network Switches

The Linux Foundation has launched a project called LF Edge framework early this year, bringing together three existing projects and two new ones in an effort to foster interoperability and collaboration across the development communities for edge computing and the Internet of Things. It added two more projects in September: Arpit Joshipura, general manager of networking at The Linux Foundation. Traditional vendors have sold Continue reading

Network Automation and the Lack of Innovation in the Management Plane

Chris Wade 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.

Packet and Sprint on Why Bare Metal Is the ‘Lowest-Common Denominator’

IFX2019. 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.” Subscribe: | Stitcher | Overcast | TuneIn 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

HashiCorp’s Consul Brings Namespace Management to the Service Mesh

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. HashiCorp is a sponsor of The New Stack. Feature image

F5 and NGINX: Going Forward with Kubernetes

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

Why Open Source Matters More for Bare Metal

IFX2019. 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

Will Kubernetes Drive Cloud Native Telcos?

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. Subscribe: | Stitcher | Overcast | TuneIn For telcos, cloud native means software solving the complex problems heavy equipment traditionally did. It all comes down to answering two questions: What are the problems Continue reading

Can Kubernetes Orchestrate the Infrastructure?

Portworx sponsored this post. 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 | 

It Takes a Community: Kubernetes’ Long Road to Dual IPv4/IPv6 Support

Portworx sponsored The New Stack’s coverage of KubeCon+CloudNativeCon North America 2019. 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. “We ignored it,” admitted KubeCon + CloudNativeCon North America 2019 conference he gave with

Ashwath Nagaraj Ashwath Nagaraj is co-founder and CTO of Aryaka, responsible for building the company’s vision and technology since its inception in 2009. He previously founded Allegro Systems; a security startup acquired by Cisco in 2001. Ashwath was also a founder of Assured Access Technologies, which developed WAN access and aggregation products. AAT was acquired by Alcatel in 1999. He holds 17 patents in storage, security, architecture and networking. 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

Snapt Launches Project Nova, a Scalable Cloud Native Application Delivery Controller

Scripting is the Wrong Approach to Automating Networks

Olivier Huynh Van Olivier Huynh Van is the CTO and co-founder of Gluware and leads the Gluware R&D team. Olivier has spent 20+ years designing and managing mission-critical global networks for such organizations as ADM Investor Services, Groupe ODDO & Cie, Natixis, Oxoid and Deutsche Bank. He holds a Master’s Degree in Electronics, Robotics and Information Technology from ESIEA in Paris, France. 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. For Continue reading

Tutorial: Explore Project Calico Network Policies with Google Kubernetes Engine

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 The post Tutorial: Explore Project Calico Network Policies with Google Kubernetes Engine appeared first on The New Stack.

Gremlin’s Scenarios Simulate Common Outages for Chaos Engineering
