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.

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.

How to shop for a colocation provider

If you want to move assets out of your data center but for whatever reason can’t shift to the cloud, a colocation, or “colo” for short, is increasingly a viable option.Colo is where the client buys the compute, storage, and networking equipment but instead of putting it into their own data centers, they put them in the data center of a hosting company. They still own and manage the hardware, but they don’t have responsibility for manage the facilities—heating, cooling, lighting, physical security, etcNow see "How to manage your power bill while adopting AI" As such, colocation facilities attract considerable interest from enterprises. IDC puts the 2020 US colocation market at $9 billion, growing to $12.2 billion by 2024 for a compound annual growth rate (CAGR) of 8%. Grand View Research estimates the global data-center colocation market size was valued at $40.31 billion US dollars in 2019 and is expected to grow at a CAGR of 12.9% from 2020 to 2027. Gartner makes the bravest prediction, saying that by 2025, 85% of infrastructure strategies will integrate on-premises, colocation, cloud, and edge delivery options, compared with 20% in 2020.To read this article in full, please click here

Will open networking lock you in?

There’s open, then there’s open.  At least that seems to be the case with network technology. Maybe it’s the popularity and impact of open-source software, or maybe it’s just that the word “open” makes you think of being wild, happy, and free—whatever it is, the concept of openness in networking is catching on. Which means, of course, that the definition is getting fuzzier every day.When I talk with enterprises, they seem to think that openness in networking is the opposite of proprietary, which they then define is a technology for which there is a single source. That suggests that open networking is based on technology for which multiple sources exist, but as logical as that sounds, it may not help much.To read this article in full, please click here
