Procella: unifying serving and analytical data at YouTube

Procella: unifying serving and analytical data at YouTube Chattopadhyay et al., VLDB’19

Academic papers aren’t usually set to music, but if they were the chorus of Queen’s “I want it all (and I want it now…)” seems appropriate here. Anchored in the primary use case of supporting Google’s YouTube business, what we’re looking at here could well be the future of data processing at Google. Well, I say the future, but “Procella has now been in production for multiple years. Today, it is deployed in over a dozen data centers and serves hundreds of billions of queries per day over tens of petabytes of data…” So maybe what we’re looking at is the future of data processing for the rest of us!

Google already has Dremel, Mesa, Photon, F1, PowerDrill, and Spanner, so why did they need yet another data processing system? Because they had too many data processing systems! ;)

Large organizations… are dealing with exploding data volume and increasing demand for data driven applications. Broadly, these can be categorized as: reporting and dashboarding, embedded statistics in pages, time-series monitoring, and ad-hoc analysis. Typically, organizations build specialized infrastructure for each Continue reading

Powering Docker App: Next Steps for Cloud Native Application Bundles (CNAB)

Last year at DockerCon and Microsoft Connect, we announced the Cloud Native Application Bundle (CNAB) specification in partnership with Microsoft, HashiCorp, and Bitnami. Since then the CNAB community has grown to include Pivotal, Intel, DataDog, and others, and we are all happy to announce that the CNAB core specification has reached 1.0.

We are also announcing the formation of the CNAB project under the Joint Development Foundation, a part of the Linux Foundation that’s chartered with driving adoption of open source and standards. The CNAB specification is available at cnab.io. Docker is working hard with our partners and friends in the open source community to improve software development and operations for everyone.

Docker’s Implementation of CNAB — Docker App

Docker was one of the first to implement the CNAB specification with Docker App, our reference implementation available on GitHub. Docker App can be used to both build CNAB bundles for Docker Compose (which can then be used with any other CNAB client), and also to install, upgrade, and uninstall any other CNAB bundle.

It also forms the underpinnings of application templates in Docker Desktop Enterprise. With Docker App, we are making CNAB-compliant applications as easy to use Continue reading

Network Operators in Mexico Strengthen Their Collaboration

Collaboration is a basic element for Internet development. Without it, connections among networks would be non-existent and the Internet wouldn’t have its global reach. Without it, the Internet wouldn’t exist as we know it. Fortunately, there are many groups that use collaboration and other elements of the Internet networking model.

On August 14, NIC Mexico convened the second meeting of network operators in the country. After a first successful meeting held in 2018, this year’s event exceeded the expectations of the organizers. Edmundo Cázarez, Internet Resource Manager at NIC Mexico, said the organization placed greater emphasis on promoting the meeting among network operators, which led to increased participation.

MEXNOG, as the group of operators is also known, has capitalized on the enthusiasm of the participants through their meetings, but also through a mailing list. In the style of other Internet development groups, the mailing list has served as a meeting point and as a space for exchanging information and best practices among participants.

Therefore, the next step for the group is to strengthen participation in this space, as Edmundo points out: “We want the mailing list to be the contact point of the group. It has been used to Continue reading

Best Magazines for an NYC Fashion Internship

New York City is considered one of the fashion capitals of the world; therefore, if you are interested in fashion and want to take an internship for a fashion magazine, finding an internship with one of the NYC fashion magazines is worth the effort. 

An NYC fashion internship at any New York fashion magazine can give you a ton of valuable experience both in the magazine and fashion industry. Not only do interns get to see the latest fashions, but they also learn how to accessorize clothing, how to set up a fashion shoot, how to work closely with fashion editors, and how to write for the magazine, review fashion shows and so much more. The experience you gain in the field of fashion at an NYC fashion internship is invaluable, whether you are a budding fashion designer or simply interested in working full time for a large fashion magazine. 

You do need to be aware that many NYC fashion internship programs are either unpaid or offer very low pay, so you will need to have some way of covering your living expenses while doing your internship. That’s why student interns usually get these jobs rather than adults. Continue reading

Response: The OSI Model Is a Lie

Every now and then I stumble upon a blog post saying “OSI 7-layer model sucks” or “OSI 7-layer model is a lie”, most recent one coming from Robert Graham.

Before going into the details, let’s agree on the fundamentals.

Most everyone who ever tried to build a network spanning more than one transmission technology and including intermediate nodes came to the conclusion that layered approach to networking makes sense.

Whether you have three, four, five, or seven layers in your model doesn’t matter. What really matters is that your model contains all the functionality you need to implement host-to-host networking in target environment.

Packet analysis using Docker

Why use sFlow for packet analysis? To rephrase the Heineken slogan, sFlow reaches the parts of the network that other technologies cannot reach. Industry standard sFlow is widely supported by switch vendors, embedding wire-speed packet monitoring throughout the network. With sFlow, any link or group of links can be remotely monitored. The alternative approach of physically attaching a probe to a SPAN/Mirror port is becoming much less feasible with increasing network sizes (10's of thousands of switch ports) and link speeds (10, 100, and 400 Gigabits). Using sFlow for packet capture doesn't replace traditional packet analysis, instead sFlow extends the capabilities of existing packet capture tools into the high speed switched network.

This article describes the sflow/tcpdump  and sflow/tshark Docker images, which provide a convenient way to analyze packets captured using sFlow.

Run the following command to analyze packets using tcpdump:

$ docker run -p 6343:6343/udp -p 8008:8008 sflow/tcpdump
