Hands On With Ansible collections

Ansible collections have been introduced previously through two of our blogs Getting Started with Ansible Content Collections and The Future of Ansible Content Delivery. In essence, Ansible Automation content is going to be delivered using the collection packaging mechanism.  Ansible Content refers to Ansible Playbooks, modules, module utilities and plugins. Basically all the Ansible tools that users use to create their Ansible Automation. Content is divided between two repositories:

  1. Ansible Galaxy (https://galaxy.ansible.com)
  2. Automation Hub (https://cloud.redhat.com/ansible/automation-hub)

Ansible Galaxy is the upstream community for sharing Ansible Collections.  Any community user can create a namespace and share content with anyone. Access to Automation Hub is included with a Red Hat Ansible Automation Platform subscription.  Automation Hub only contains fully supported and certified content from Red Hat and our partners. This makes it easier for Red Hat customers to determine which content is the official certified, and importantly supported, content.  This includes full content from partners such as Arista, Cisco, Checkpoint, F5, IBM, Microsoft and NetApp. 

In this blog post we'll walk through a use case wherein, the user would like to use a Red Hat certified collection from Automation Hub Continue reading

The Bandwidth Alliance Charges Forward with New Partners – Alibaba, Zenlayer, and Cherry Servers

The Bandwidth Alliance Charges Forward with New Partners - Alibaba, Zenlayer, and Cherry Servers

We started the Bandwidth Alliance in 2018 with a group of like-minded cloud and networking partners. Our common goal was to help our mutual customers reduce or eliminate data transfer charges, sometimes known as "bandwidth” or “egress” fees, between the cloud and the consumer. By reducing or eliminating these costs, our customers can more easily choose a best of breed set of solutions because they don’t have to worry about data charges from moving workloads between vendors, and thereby becoming locked-in to a single provider for all their needs. Today we’re announcing an important milestone: the addition of Alibaba, Zenlayer, and Cherry Servers to the Bandwidth Alliance, expanding it to a total of 20 partners. These partners offer our customers a wide choice of cloud services and products each suited to different needs.

In addition, we are working with our existing partners including Microsoft Azure, Digital Ocean and several others to onboard customers and provide them the benefits of the Bandwidth Alliance. Contact us at [email protected] if you are interested.

Customer savings  

Over the past year we have seen several customers take advantage of the Bandwidth Alliance and wanted to highlight two examples.

A Backdoor Is a Backdoor Is a Backdoor

Beware of false promises and threats to encryption security online.

It’s easy to understand why United States Federal Bureau of Investigation (FBI) Director Christopher Wray would ask companies to provide a means for law enforcement to access private data and communications.

“We’re all for strong encryption and… we are not advocating for ‘backdoors,'” he said at recent cyber security conference. “We’ve been asking for providers to make sure that they, themselves, maintain some kind of access to the encrypted data we need, so that they can still provide it in response to a court order.”

We all want to thwart criminals from using the Internet for harm. But here’s the catch: despite Wray’s claims, there is no way to comply with his request without breaking the security we all rely on to keep people, communications, and data safe online.

No matter what you call it, a backdoor is a backdoor. Any method that gives a third-party access to encrypted data creates a major vulnerability that weakens the security of law-abiding citizens and the Internet at large.

Encryption is essential to security online.

Consider how it contributes to the global effort to contain the COVID-19 pandemic. Encryption protects the electricity Continue reading

Why We Started Putting Unpopular Assets in Memory

Why We Started Putting Unpopular Assets in Memory
Fun lede about why we write unpopular cache assets to memory.
Why We Started Putting Unpopular Assets in Memory

Part of Cloudflare's service is a CDN that makes millions of Internet properties faster and more reliable by caching web assets closer to browsers and end users.

We make improvements to our infrastructure to make end-user experiences faster, more secure, and more reliable all the time. Here’s a case study of one such engineering effort where something counterintuitive turned out to be the right approach.

Our storage layer, which serves millions of cache hits per second globally, is powered by high IOPS NVMe SSDs.

Although SSDs are fast and reliable, cache hit tail latency within our system is dominated by the IO capacity of our SSDs. Moreover, because flash memory chips wear out, a non-negligible portion of our operational cost, including the cost of new devices, shipment, labor and downtime, is spent on replacing dead SSDs.

Recently, we developed a technology that reduces our hit tail latency and reduces the wear out of SSDs. This technology is a memory-SSD hybrid storage system that puts unpopular assets in memory.

The end result: cache hits from our infrastructure are now faster for all customers.

You may have thought that was a Continue reading

Automation Example: Drain a Circuit

One of the attendees of our Building Network Automation Solutions online course asked an interesting question in the course Slack team:

Has anyone wrote a playbook for putting a circuit into maintenance mode — i.e. adjusting metrics to drain traffic away from a circuit that is going to be taken down for maintenance?

As always, you have to figure out what you want to do before you can start to automating stuff.

Insecurity

We need a secure and trustable infrastructure. We need to be able to provide assurance that the service we are contacting is genuine, that the transaction is secured from eavesdroppers and that we leave no useful traces behind us. Why has our public key certificate system failed the Internet so badly?

IETF 107 Starts Today as a Virtual Meeting

A view of Vancouver from Skylab - photo from NASA

Later today, the 107th meeting of the Internet Engineering Task Force (IETF) will begin its working group sessions in an unconventional way. Previously, over 1,000 engineers were expected to be in Vancouver, Canada, to engage in the IETF’s work creating the open standards that make the Internet possible.

But with the global COVID-19 pandemic, the IETF leadership decided to cancel the in-person meeting in Vancouver. Instead a scaled-down, completely virtual meeting will take place. Only 12 of the IETF’s 115+ working groups will be meeting this week. Other working groups, and the research groups of the Internet Research Task Force (IRTF) may schedule interim meetings in the weeks and months ahead.

You can participate remotely in IETF 107. The steps are all outlined in this “Guide for IETF 107 Participants“. Useful resources include:

To be clear, most of the work of the IETF in creating the Internet’s open standards ALREADY takes place online. People create “Internet-Draft” documents that propose new ways to make the Internet work better. Those documents are discussed and debated on email lists for working groups. Eventually those working groups reach “rough consensus” and Continue reading
