Top 12 Questions from the Docker Enterprise 3.0 Webinar Series

Earlier in August, we hosted a series of virtual events to introduce Docker Enterprise 3.0. Thousands of you registered and joined us, and many of you asked great questions. This blog contains the top questions and answers from the event series.

Docker Enterprise in the Cloud, On-Prem, with Kubernetes

Q: Can Docker Enterprise be used on AWS and other cloud providers?

A: Yes! Docker Enterprise, including the Docker Universal Control Plane (UCP) and Docker Trusted Registry (DTR), can be deployed to any of the leading cloud environments, including AWS, Azure and GCP. With Docker Enterprise 3.0, we also launched the Docker Cluster CLI plugin for use with Docker Certified Infrastructure. The plugin (now supporting AWS and Azure) allows for simple installation and upgrading of Docker Enterprise on selected cloud providers.

Q: Is Docker Cluster only available in the public cloud, or is it possible to add local machines or VMs?

A: Additional support for VMware vSphere environments is coming shortly. If you have other platforms that need to be supported, please engage with your account team to provide that feedback!

Q: Does Docker Kubernetes Service (DKS) work with both on-premises and other Kubernetes environments such as EKS, AKS, Continue reading

Unix as a Second Language: The touch command

The Linux touch command allows users to create an empty file or update a file’s data and time settings.You might want to do this if you need to be sure that a file exists before a script or process begins. The command can also be used to set the date and time to match those of another file.Watch this Two-minute Linux Tip video by Sandra Henry-Stocker to learn more.

Intel’s new 10nm Agilex FPGA will help customers develop IoT, 5G solutions

Intel announced this week it has begun shipping its 10nm Agilex FPGAs to early-access customers, including Microsoft, featuring the Compute Express Link (CXL), a cache and memory coherent CPUs-to-anything interconnect that has an industry consortium of more than 60 members. The company first announced the chips in April.The Agilex FPGA is the product of the Altera group, which Intel bought in 2015 for $16.7 billion. It sold FPGAs under the Stratix brand name, but this line is the first to come out under Intel ownership. CXL replaces OmniPath Connect, a fabric Intel developed but no one else supported. The company ended support for OmniPath earlier this month in favor of CXL, which has wide industry support.To read this article in full, please click here

Bluetooth finds a role in the industrial internet of things

Like most people, I think of Bluetooth as a useful but consumer-oriented technology that lets me make easy wireless connections from my smartphone to various headsets, portable speakers, automobile, and other devices. And, of course, billions of people rely on Bluetooth for exactly those capabilities. But according to Chuck Sabin, senior director of market development for the Bluetooth SIG, the technology is growing into a key role in the industrial internet of things (IIoT).To read this article in full, please click here

Announcing the General Availability of API Tokens

APIs at Cloudflare

Today we are announcing the general availability of API Tokens - a scalable and more secure way to interact with the Cloudflare API. As part of making a better internet, Cloudflare strives to simplify manageability of a customer’s presence at the edge. Part of the way we do this is by ensuring that all of our products and services are configurable by API. Customers ranging from partners to enterprises to developers want to automate management of Cloudflare. Sometimes that is done via our API directly, and other times it is done via open source software we help maintain like our Terraform provider or Cloudflare-Go library. It is critical that customers who are automating management of Cloudflare can keep their Cloudflare services as secure as possible.

Least Privilege and Why it Matters

Securing software systems is hard. Limiting what a piece of software can do is a good defense to prevent mistakes or malicious actions from having greater impact than they could. The principle of least privilege helps guide how much access a given system should have to perform actions. Originally formulated by Jerome Saltzer, “Every program and every privileged user of the system should operate using Continue reading

Choosing a cloud DBMS: architectures and tradeoffs

Choosing a cloud DBMS: architectures and tradeoffs Tan et al., VLDB’19

If you’re moving an OLAP workload to the cloud (AWS in the context of this paper), what DBMS setup should you go with? There’s a broad set of choices including where you store the data, whether you run your own DBMS nodes or use a service, the kinds of instance types to go for if you do run your own, and so forth. Tan et al. use the TPC-H benchmark to assess Redshift, Redshift Spectrum, Athena, Presto, Hive, and Vertica to find out what works best and the trade-offs involved.

We focused on OLAP-oriented parallel data warehouse products available for AWS and restricted our attention to commercially available systems. As it is infeasible to test every OLAP system runnable on AWS, we chose widely-used systems that represented a variety of architectures and cost models.

My key takeaways as a TL;DR:

• Store your data in S3
• Use portable data format that gives you future flexibility to process it with multiple different systems (e.g. ORC or Parquet)
• Use Athena for workloads it can support (Athena could not run 4 of the 22 TPC-H queries, and Spectrum could not run Continue reading

Video: Introducing Transmission Technologies

After discussing the challenges one encounters even in the simplest networking scenario connecting two computers with a cable we took a short diversion into an interesting complication: what if the two computers are far apart and we can’t pull a cable between them?

Trying to answer that question we entered the wondrous world of transmission technologies. It’s a topic one can spent a whole life exploring and mastering, so we were not able to do more than cover the fundamentals of modulations and multiplexing technologies.

Rating IoT devices to gauge their impact on your network

One difficulty designing IoT implementations is the large number of moving parts. Most IoT setups are built out of components from many different manufacturers – one company’s sensors here, another’s there, someone else handling the networking and someone else again making the backend.To help you get a ballpark sense of what any given implementation will demand from your network, we’ve come up with a basic taxonomy for rating IoT endpoints. It’s got three main axes: delay tolerance, data throughput and processing power. Here is an explainer for each. (Terminology note: We’ll use “IoT setup” or “IoT implementation” to refer to the entirety of the IoT infrastructure being used by a given organization.)To read this article in full, please click here

Quest Levels Up, Announces Foglight Evolve Platform

Data center-specific AI completes tasks twice as fast

Data centers running artificial intelligence (AI) will be significantly more efficient than those operating with hand-edited algorithm schedules, say experts at MIT. The researchers there say they have developed an automated scheduler that speeds cluster jobs by up to 20 or 30 percent, and even faster (2x) in peak periods.The school’s AI job scheduler works on a type of AI called “reinforcement learning” (RL). That’s a trial-and-error-based machine-learning method that modifies scheduling decisions depending on actual workloads in a specific cluster. AI, when done right, could supersede the current state-of-the-art method, which is algorithms. They often must be fine-tuned by humans, introducing inefficiency.To read this article in full, please click here
