In Datanauts episode 80, we bemoaned the state of network automation. In the many comments we received on that episode, one especially stuck out to me. Here’s a paraphrase. “Tools like Cisco Network Services Orchestrator can automate an entire network, and not just push config changes box by box. You tell the tool what your network is, and the tool computes the changes needed throughout the network for you.” Today, we’re going to chat with sponsor Cisco about Network Services Orchestrator, and see how network automation has improved in the last couple of years. Our guest is Carl Moberg, Technology Director at Cisco Systems. Carl provides background on Network Services Orchestrator and delves into key issues including: * NSO support for Cisco and non-Cisco physical and virtual gear * The NSO architecture and configuration workflows * NSO use cases * The service developer role and how it fits into NSO * Network automation challenges * New features and capabilities * More Show Links: Cisco Network Services Orchestrator – Cisco Systems Cisco Network Services Orchestrator (NSO): The Bridge To Automation – Cisco Systems (PDF) Carl Moberg on Twitter PQ Show 116: Practical YANG For Network Automation – Packet Pushers

Your CIO recently returned from a global strategy summit in Vegas and sent an all-company memo announcing that the company’s cloud-first strategy is now a “multi-cloud” strategy. Then your boss wanders in to ask you how long until that multi-cloud strategy will be fully implemented. You wonder what they mean by multi-cloud. Do they even know? Why is the organization doing this? Why is my coffee cold? Today’s Day Two Cloud episode examines the motivations that drive organizations to multi-cloud, and the consequences of that decision. Going multi-cloud may sound like a great idea–and it might actually be, depending on your organization’s needs–but it’s full of trap doors in terms of training, operations, security, and cost. My guest is Alex Neihaus, a Cloud Infrastructure Architect with Air11 Technology. We discuss the business, technical, and process implications of multi-cloud. Show Links: Alex Neihaus on Twitter

The cloud is a set of design principles, not a location. Those design principles can be applied to the data center and data center networks. That’s the gist of today’s Tech Bytes conversation with sponsor Big Switch Networks. We discuss how Big Switch lets engineers use the same tools and techniques as major cloud providers to operate the data center network like an AWS VPC. That also means network engineers can provide a developer-friendly network while still setting and enforcing policies, enabling security controls, and getting visibility into network operations and performance. We discuss how Big Switch makes this possible on premises and in public clouds with Paul Unbehagen, CTO at Big Switch.

Ethan Banks and Drew Conry-Murray were delegates at a recent Networking Field Day Extra to hear from 128 Technology. 128 Technology makes a software router that runs on x86. There are a variety of software-based routers on the market. What sets 128T apart is how it does the routing. For example: * The 128T router is session-based and stateful * It’s secure via policy, with a zero-trust posture * Operators can set policies to determine the network path depending on SLAs and changing network characteristics * The router relies on packet metadata and NAT to direct packets * The router uses AES-256 or 128 to encrypt metadata in the first packet, and the payload in every packet in a session Use Cases The speakers from 128 Technology outlined several use cases for their software router: * Routing/connectivity in locations with significant bandwidth constraints, such as satellite * SD-WAN (including cloud traffic optimization) * VoIP/call centers * L4 firewall (not an NG or UTM platform, but you can do service chaining for the fancy stuff) * “We’re going after the routing market. Not just the SD-WAN market.” NAT Vs. Tunneling The 128 Technology presentations go to great pains to explain that they don’t rely on tunneling or encapsulation to get packets from source to destination. By eschewing tunnels, 128 Technology claims several benefits: * Efficiency gains of ~ 30% demonstrated (i.e. more throughput due to less tunnel overhead, matters more when bandwidth-constrained) * Reduced risk of fragmentation / having to tweak TCP MSS or MTU * If there is fragmentation required (metadata adds ~150-200 bytes of overhead depending on policy complexity), they will fragment/reassemble within their own fabric Show Links: 128 Networking Field Day Exclusive with 128Technology – TechFieldDay Networking Field Day Videos on YouTube Event playlist 128 Technology Networking Platform Overview 128 Technology Service Centricity via the 128T Networking Platform Data Model 128 Technology Routing Protocols: SVR 128 Technology Routing Protocols: STEP 128 Technology Why Tunnel Free is Better and How We’re Different from Legacy Overlays

There’s a flurry of activity around network automation, lots of discussion about its impacts, and a host of open-source and commercial tools available. But actual adoption? Not so much. Today’s Datanauts podcast explores NRE Labs, a free site to train network engineers in basic automation concepts and tools. NRE stands for “Network Reliability Engineering”. As guest Matt Oswalt describes it, the goal of NRE Labs is to help network engineers take that first automation step, get unstuck, and get started. Matt is an “engineer in marketing clothing” at Juniper Networks. While NRE Labs is a Juniper-sponsored project, you don’t have to be a Juniper customer. You don’t even have to sign up and hand over any information to use it. The site is entirely free. You just go to the homepage, find a lesson or topic that looks interesting, and get started. The site is designed to work within a browser so there’s no software to download and no complicated virtual environment to configure. The code that powers NRE Labs is open-source so you can grab it for yourself. The project also welcomes contributions and lessons from the community. In today’s podcast, Matt walks Chris Wahl through NRE Labs, describes how it works, explains a couple of lessons, and shares how the community can get involved.

You’ve got to get to the cloud!  It’s a moral imperative, or at the very least it’s a corporate directive. And on the way you’d like to embrace infrastructure as code, DevOps, and serverless: you know, all the cool buzzwords. But how do you actually integrate those technologies into your day-to-day workflow? How do you create an initial environment, and how to you update that environment after day one? What was the glowing thing in the briefcase from Pulp Fiction? We’ll try to get to the bottom of some of these questions on today’s show. In this episode, we’ll discuss some important points on day two adoption of cloud technologies. We’ll go through the challenges of making that transition from day one to day two in terms of training, adoption, and governance. My guest is Mark Gossa, an infrastructure engineering lead for a London-based bank. Besides the day one to day two transition, we talk about how his organization uses DevOps principles without creating a “DevOps team,” how to select a tool to automate Azure infrastructure deployments, and briefly discuss options such as Terraform and ARM templates. We’ll also discuss how Azure DevOps can provide full end-to-end management from Azure Boards and Azure Repos all the way through to Azure Pipelines.

Organizations don’t have to be convinced to adopt the cloud these days. The conversation now is about how to do it right. The cloud is not just another data center or just another IT project; it’s a transformation in how you build, operate, and consume cloud applications and technologies, and how you support people and objectives. Joining me today to provide some expert guidance on the right way to adopt cloud is Dwayne Monroe, a Cloud Architect for Cloudreach. We discuss: * The wrong way of doing cloud (no refactoring, sizing servers as you would on premises, etc.) * Why organizations fail to design with cost in mind * The need for a cloud team that crosses IT and business domains and disciplines * Why you should explore PaaS and serverless, not just IaaS * IT’s shared responsibility to design for service availability and security * Why staff training is a must * Laying the groundwork to refactor applications once they’re in the cloud * More Show Links: Dwayne Monroe on Twitter Dwayne Monroe on LinkedIn The Azure Cmdlet Project Using a Cloud Center of Excellence (CCOE) to Transform the Entire Enterprise – Amazon Prevent unexpected charges with Azure billing and cost management – Microsoft Choosing the right service in Azure – Microsoft Cloud Cost Control & Architecture (or, how to avoid sticker shock) – Dwayne Monroe

Drew Conry-Murray and Ethan Banks had a briefing with a startup called Edgeworx on June 24th, 2019. You can read their highlights of the Kubernetes-related news Edgeworx shared below, or listen to the audio version in the player above. What Does Edgeworx Do? As you might guess from the name, Edgeworx focuses on the network edge; that is, on security cameras, or local compute at a cell tower base station or on an offshore oil rig, for example. The startup’s big idea is to make it easy for organizations to re-use applications they’ve written for other platforms and run those applications on edge devices. If you want to do local processing on edge devices, Edgeworx wants to provide the platform to run applications on those devices. Edgeworx says it can run on almost anything: security cameras and other IoT devices, IoT gateways, Wif-Fi routers, cars, etc. The company does have minimum hardware & software specs. Edgeworx needs some distro of Linux, a minimum of a 32-bit ARM processor, and 128MB of RAM. If the device meets those minimums, Edgeworx can run. The startup also makes an agent that runs on IoT and edge devices to manage and control devices, provision devices, monitor health, set policies and get alerts. Mesh Networking And AMQP Edgeworx enables devices to connect to one another using AMQP 1.0, or the Advanced Message Queing Protocol. This is the basis for edge-to-edge, edge-to-cloud, and cloud-to-edge networks–whatever is required for a given edge computing environment. Kubernetes Customized For Edge Computing The big news from this briefing is that Edgeworx now gives Kubernetes specific intelligence about the edge computing environment: the device capabilities, GPS geolocation, etc. This means that edge computing environments can enjoy the scheduling benefits of Kubernetes, while at the same time getting workload placements in a way that works well with edge computing environments’ unique needs.

I hear about companies that create net new DevOps roles and hire “DevOps Engineers” to fill them. And then those DevOps people fail in their roles, because no one wants to deal with the additional processes they tend to create. I’ve wondered if hiring specific DevOps roles is doing it wrong. Is a transformative approach a better idea? That is, take the people you’ve got and retrain, retool, and reorganize. Foster a different culture that’s DevOps-ian in nature. Then, you might be successful. Am I right? We explore this idea of hiring DevOps on the Datanauts podcast with guest Matt Stratton. Matt is a DevOps advocate at PagerDuty. We discuss: * Core DevOps principles and how to separate out marketing nonsense * Why every IT professional in an organization needs to understand the business * Whether there are costs to an IT team to moving to DevOps, and costs for not moving * DevOps success stories * Dealing with the inevitable people problems * Iterative steps you can take to creating a DevOps culture Sponsor: Tufin Tufin has pioneered a policy-based approach to network security management using automation and analytics.
