Top Questions Answered: Docker and Kubernetes? I Thought You Were Competitors!

Last week, we covered some of the questions about container infrastructure from our recent webinar “Demystifying VMs, Containers, and Kubernetes in the Hybrid Cloud Era.” This week, we’ll tackle the questions about Kubernetes, Docker and the software supply chain. One common misperception that we heard in the webinar — that Docker and Kubernetes are competitors. In fact, Kubernetes is better with Docker. And Docker is better with Kubernetes.

Docker And Kubernetes? I thought you were competitors?

We hear questions along this line all the time. Here are some quick answers:

Can I use Kubernetes with Docker?

  • Yes, they go together. You need a container runtime like Docker Engine (based on open source containerd) to start and stop containers on a host.
  • When you have a bunch of containers running across a bunch of hosts, you need an orchestrator to manage things like: Where will the next container start? How do you make a container highly available? How do you control which containers can communicate with other containers? That’s where an orchestrator such as Kubernetes comes in.
Comparing traditional, virtualized, containerized and Kubernetes deployment architectures.
  • The container runtime and the orchestrator are the two core atomic units that Continue reading

The Week in Internet News: Governments Pressure Facebook to Halt Encryption Plans

Anti-encryption demands: Government officials from the U.S., U.K., and Australia have asked Facebook to put a hold on its plans to expand encryption on services like Messenger, CNet reports. “We are writing to request that Facebook does not proceed with its plan to implement end-to-end encryption across its messaging services without ensuring that there is no reduction to user safety and without including a means for lawful access to the content of communications to protect our citizens,” says a letter signed by U.S. Attorney General William Barr and other officials.

This law is not fake: A new fake news law in Singapore has taken effect, SPDP Radio says. The law includes penalties of up to US $60,000 and 10 years in prison for people found guilty of spreading what the government considers to be fake news. Web sites could face fines of more than $720,000 for not taking down so-called fake news after being ordered to do so. Free speech advocates have major problems with the law, as you might expect.

The lines are cut: Internet access in most of Iraq was shut down after violent protest in the country, CNet says. Some people were Continue reading

150 successful machine learning models: 6 lessons learned at Booking.com

150 successful machine learning models: 6 lessons learned at Booking.com Bernadi et al., KDD’19

Here’s a paper that will reward careful study for many organisations. We’ve previously looked at the deep penetration of machine learning models in the product stacks of leading companies, and also some of the pre-requisites for being successful with it. Today’s paper choice is a wonderful summary of lessons learned integrating around 150 successful customer facing applications of machine learning at Booking.com. Oddly enough given the paper title, the six lessons are never explicitly listed or enumerated in the body of the paper, but they can be inferred from the division into sections. My interpretation of them is as follows:

  1. Projects introducing machine learned models deliver strong business value
  2. Model performance is not the same as business performance
  3. Be clear about the problem you’re trying to solve
  4. Prediction serving latency matters
  5. Get early feedback on model quality
  6. Test the business impact of your models using randomised controlled trials (follows from #2)

There are way more than 6 good pieces of advice contained within the paper though!

We found that driving true business impact is amazingly hard, plus it is difficult to isolate Continue reading

Xilinx unveils open source FPGA platform

The Vitis unified software platform from FPGA vendor Xilinx is the result of five-year project to create software development tools using familiar languages like C++ and Python to develop a wide range of applications for its reprogrammable chip.The beauty of FPGAs (Field Programmable Gate Arrays) is their configurable, adaptable nature. That's also what makes programming them a king-sized challenge. They're difficult to work with for an unskilled programmer who is not well versed in hardware, and they often require esoteric languages.Vitis supports heterogeneous architectures including Xilinx’s Zynq SoCs, MPSoCs, and Versal ACAPs. Vitis is designed to enable highly optimized, domain-specific acceleration to a wide array of applications, from cloud deployments, to machine learning and AI, to IoT and desktop applications. Think of it as being for Xilinx what CUDA is to Nvidia.To read this article in full, please click here

Site-to-Site OpenVPN on VyOS

The tutorial discusses configuration of site-to-site VPN on VyOS using preshared-key. Static key configuration offers the simplest setup, and is ideal for point-to-point VPNs or proof-of-concept testing. The advantages of using static key are simple setup and no X509 PKI (Public Key Infrastructure) to maintain. The disadvantages are limited scalability - one client, one server setup and the lack of perfect forward secrecy - key compromise results in a total disclosure of previous sessions. Also, a secret key must exist in plain-text form on each VPN peer and it must be exchanged using a pre-existing secure channel.

Our lab consists of two remote sites (Picture 1). The router running network OS - VyOS is presented on each side, connecting computers PC and PC2 to to a particular LAN network. The both VyOS routers are configured forOpenVPN site-to-site mode and the routers also perform NAT (PAT) and firewall services.
