Cisco DevNet certifications: 10k awarded in first year

In the year since Cisco revamped its DevNet certification portfolio to focus more on network programing, automation and application development, the need for those software-based skillsets has never been more important. IT Salary Survey on Insider Pro IT Salary Survey 2021: The results are in IT Salary Survey 2021: Compensation holds steady despite pandemic IT Salary Survey 2021: Hiring rate expected to increase but priorities will shift IT Salary Survey 2021: Over half of IT pros are satisfied at work – but nearly half are job hunting IT Salary Survey 2021: Security and cloud computing certifications on the up The requirement for software skills in the networking environment is being driven by a number of factors including the tremendous increase in the use of automation, the need to have an intelligent pipeline to remote users, and the growing necessity to efficiently network and secure multicloud resources. Many of these changes were already underway of course, but tons more are being driven by the COVID-19 pandemic’s impact on many enterprise data-center, campus and wide area network operations.To read this article in full, please click here

First look: new O’Reilly eBook on Kubernetes security and observability *early release chapters*

We are excited to announce the early release of a new O’Reilly eBook on Kubernetes security and observability!

This practical book introduces new cloud-native approaches for Kubernetes practitioners who care about the security and observability of mission-critical microservices. Through practical guidance and best practice recommendations, this book helps you understand why cloud-native applications require a modern approach to security and observability practices and how to implement them.

You should read this book if you want to:

  • learn why you need a security and observability strategy for cloud-native applications, and determine your scope of coverage;
  • understand key concepts behind Kubernetes’s security and observability approach;
  • discover how to split security responsibilities across multiple teams or roles; and/or
  • learn how to architect Kubernetes security and observability for multi-cloud and hybrid environments.

Whether you want to know how to secure and troubleshoot your cloud-native applications, or are exploring Kubernetes for your organization and would like to solve security and observability challenges before making a decision, you will find that this book provides valuable insight.

Automating a RHEL 8 Installation Using the VMware REST Ansible Collection

Managing virtual machines in an IT infrastructure is often a common task, specifically VMware virtualization technology has been around for over 20 years. VMware administrators spend a lot of their time in automating the creation, management, and removal of virtual instances that contain various operating systems. One operating system that often resides on VMware infrastructure is Red Hat Enterprise Linux. 

With the introduction of VMware REST APIs, we recently announced the initial release of the vmware.vmware_rest Collection, for production use. As opposed to the community.vmware Collection, the vmware.vmware_rest Collection is based on next generation VMware REST APIs.  This new Collection no longer requires any third party Python bindings to communicate with VMware infrastructure. A large part of the new Collection that has been introduced is support for automating virtual machine operations.

In this blog post I will show you how VMware users can automate the installation of Red Hat Enterprise Linux 8 (RHEL 8) using the vmware.vmware_rest.vcenter_vm module and a valid Kickstart file.

 

Scenario requirements

For this scenario, we will assume following requirements:

  1. vCenter 7.0.1 or latest with at least one ESXi 
  2. RHEL 8 installation DVD
  3. Ansible
  4. vmware.vmware_rest Continue reading

4 Data Center Security Issues That Will Make You Rethink Firewalling

Recall what was happening a decade ago? While 2011 doesn’t seem that long ago (you remember, the Royal Wedding, Kim Kardashian’s divorce, and of course Charlie Sheen’s infamous meltdown), a lot has changed in 10 years. Back then, most data centers were just starting to experiment with virtualization. Remember when it was considered safe for only a handful of non-essential workloads to go virtual? Well, today about half of the servers globally have become virtualized, and we’ve moved well beyond just virtualization. Nearly every enterprise data center has become a hybrid environment, with a mix of physical and virtual storage and compute resources. Containerization and the technologies supporting it are starting to take hold. And of course, cloud computing has become pervasive in all aspects of enterprise computing. 

Now, the business benefits of today’s software-defined data center are many, especially in terms of resource efficiency and cost savings. But there’s no denying that complexity has also increased, because all the same resources are still needed—compute, storage, switching, routing—but now any number of these resources may be on-prem or in the Continue reading

Loose Lips

When I was in the military we were constantly drilled about the problem of Essential Elements of Friendly Information, or EEFIs. What are EEFis? If an adversary can cast a wide net of surveillance, they can often find multiple clues about what you are planning to do, or who is making which decisions. For instance, if several people married to military members all make plans to be without their spouses for a long period of time, the adversary can be certain a unit is about to be deployed. If the unit of each member can be determined, then the strength, positioning, and other facts about what action you are taking can be guessed.

Given enough broad information, an adversary can often guess at details that you really do not want them to know.

What brings all of this to mind is a recent article in Dark Reading about how attackers take advantage of publicly available information to form Spear Phishing attacks—

Most security leaders are acutely aware of the threat phishing scams pose to enterprise security. What garners less attention is the vast amount of publicly available information about organizations and their employees that enables these attacks.

Developer Challenges

Welcome to Developer Week at Cloudflare! We are excited to announce we are running a series of Developer Challenges throughout the week to give you the excuse you needed to play with all our new features.

Between now and April 19 you’ll get to know the Cloudflare developer tools and walk away with a fun new app (or five) to your name. You’ll also become a part of the Cloudflare Developer community!

We hope that some of you will be inspired to create your next project using Cloudflare Workers, Workers KV, Pages, Durable Objects and all the developer-focussed products that Cloudflare offers. There’s already a vibrant community building applications using the Workers ecosystem; we hope the Developer Challenges inspire you to build on Cloudflare.

What are Developer Challenges?

We know that some people are new to the Cloudflare services for developers and that some of you have been using them for a while, so we have come up with two streams of challenges.

If you’re just getting started with Cloudflare, there will be a new challenge each day of the week that will help you level up your knowledge in no time. There’s also an extra bonus challenge Continue reading

Live stream to multiple platforms with Stream Connect

Live stream to multiple platforms with Stream Connect
Live stream to multiple platforms with Stream Connect

Today, we are announcing the Stream Connect beta, the first step towards supporting end-to-end live broadcasting on Cloudflare. You can use Stream Connect to push RTMPS feeds to the Cloudflare edge and have it restreamed to your audience on any platform that supports RTMPS such as Facebook, YouTube and Twitch.

What is restreaming?

Facebook, YouTube and Twitch are great platforms for creators to broadcast live video to reach billions. They each have their own unique communities and benefits for creators. If you have a band and want to broadcast a live performance for your fans, broadcasting to only one platform limits your reach. Restreaming enables you to push the live video to multiple platforms at the same time so you can meet your fans on their preferred platform.

Live video platforms accept incoming connections using a protocol called RTMP or RTMPS. Stream Connect allows you to continue using the same protocol as before. However, instead of using your local connection to send the video feed to multiple platforms, you only send it to Stream Connect. Connect uses the Cloudflare network to send your live feed to the configured media platforms.
