Docker 101: Introduction to Docker webinar recap

Docker is standardizing the way to package applications, making it easier for developers to code and build apps on their laptop or workstation and for IT to manage, secure and deploy into a variety of infrastructure platforms

In last week’s webinar, Docker 101: An Introduction to Docker, we went from describing what a container is, all the way to what a production deployment of Docker looks like, including how large enterprise organizations and world-class universities are leveraging Docker Enterprise Edition (EE)  to modernize their legacy applications and accelerate public cloud adoption.

If you missed the webinar, you can watch the recording here:

We ran out of time to go through everyone’s questions, so here are some of the top questions from the webinar:

­Q: How does Docker get access to platform resources, such as I/O, networking, etc.­ Is it a type of hypervisor?

A: Docker EE is not a type of hypervisor. Hypervisors create virtual hardware: they make one server appear to be many servers but generally know little or nothing about the applications running inside them. Containers are the opposite: they make one OS or one application server appear to be many isolated instances. Containers explicitly must know the Continue reading

History of Networking: Quality of Service with Fred Baker

Some folks over at the Network Collective thought it would be cool to sit around with folks who invented various networking technologies and just talk about the where, why, and how of those technologies were invented. Donald Sharp and I, while not officially a part of the collective, are hosting this new video cast, and the first edition just published.

For this videocast, we’re sitting down with Fred Baker to talk about the origins of Quality of Service. Hopefully we will have Fred on again in the future to talk about Raven and some of the history around network surveillance. You can watch it here, or you can jump over to the main Network Collective site and watch it there.

Virtual networking optimization and best practices

Network optimization is an incredibly important component to scalability and efficiency. Without solid network optimization, an organization will be confronted with a quickly building overhead and vastly reduced efficiency. Network optimization aids a business in making the most of its technology, reducing costs and even improving upon security. Through virtualization, businesses can leverage their technology more effectively — they just need to follow a few virtual networking best practices.

Prioritize the most important applications

There are certainly applications that are optional, but there are others that are critical. The most important applications on a network are the ones that need to be prioritized in terms of system resources. These are generally cyber security suites, firewalls, and monitoring services. Optional applications may still be preferred for business operations, but because they aren’t critical they can still operate slowly in the event of system wide issues.

Prioritizing security applications is especially important as there are many cyber security exploits that operate with the express purpose of flooding the system until security elements fail. When security apps are prioritized, the risk of this type of exploit is greatly reduced.

Install application monitoring services

Application monitoring services will be able to automatically detect when Continue reading

Accelerating Deep Learning Insights With GPU-Based Systems

Worth Reading: The IPv4 market

In September 2015, the free pool of IPv4 numbers available through the American Registry for Internet Numbers (ARIN) ran dry. In 2016, the IPv4 market was the only reliable source of IPv4 numbers, globally, and the pattern of activity changed dramatically. So far in 2017, we have seen the trends in the last half of 2016 continue. —Janine Goodman @ CircleID

Net Neutrality (Again and Again and Again)

Net neutrality is one of those topics that should never have existed, but of course it inevitably erupts every so often, so here we go…

Not so long ago Robert Graham published his anti-net-neutrality arguments which are (no surprise) not much different from what I wrote when I still cared about this argument (here, here, here and here). While I agree with his overall perspective, I completely disagree with his view of Comcast’s initial response to network congestion.

Worth Reading: Encryption substitutes

Policy experts have suggested that the rise of encrypted data is not the end of intelligence collection because law enforcement can look to substitutes other sources of intelligence, such as metadata that prove to be just as valuable or more valuable than decrypting encrypted data. This paper focuses on the other side of that insight: on the substitutes available for privacy-seekers beyond encryption, such as placing one’s data in a jurisdiction that is beyond the reach of law enforcement. This framework puts encryption in context: there are many ways to keep one’s data private, just as there are many ways that the government might get access to that data. While encryption is typically treated as a stand-alone computer security issue, it is a piece of a larger debate about government access to personal data. —Andrew Keane Woods @ Scirbd
