Advancing Windows Containers with Docker and Kubernetes

Today, the Cloud Native Computing Foundation (CNCF) announced Kubernetes 1.14,  which includes support for Windows nodes. Kubernetes supporting Windows is a monumental step for the industry and it further confirms the work Docker has been doing with Microsoft to develop Windows containers over the past five years. It is evidence that containers are not just for Linux; Windows and .NET applications represent an important and sizeable footprint of applications that can benefit from both the Docker platform and Kubernetes.

Docker’s collaboration with Microsoft started five years ago. Today, every version of Windows Server 2016 and later ships with the Docker Engine – Enterprise. In addition, to facilitate a great user experience with Windows containers, Microsoft publishes more than 129 Windows container images of its popular software on Docker Hub. Many Docker Enterprise customers are already running mixed Windows and Linux containers with Swarm, and an upcoming release of Docker Enterprise will allow our customers to expand their Windows options to Kubernetes as well. Today both Docker Enterprise and Docker Desktop users have found that the easiest way to use and manage Kubernetes is with Docker and now these users will have the same benefits with Windows containers as well.

We’ve all been there: getting booted off a call, only to find it impossible to join later, or dealing with frustrating limits to the number of people who can join the conference — the list of issues goes on. Now is the time to get an easy-to-use online meeting solution that’s made to scale for businesses of all types: RingCentral Meetings™. To read this article in full, please click here

BrandPost: Top 4 Edge Computing Challenges that IT Solution Providers Can Solve

The global edge computing market size is projected to reach $3.24 billion US by 2025 (according to a study conducted by Grand View Research, Inc.). While this research underscores the speed and volume at which edge computing installations are growing, it masks the idea that many organizations still consider themselves in the early adoption phases of this technology. Before companies plan the move to widespread rollouts, they are seeking answers to significant deployment questions.To read this article in full, please click here

Tips for using the Ip command to print from Linux systems

The lp command on Linux systems offers a range of printing options that allow you to print documents using a variety of options. In this post, we take a look at some that offer interesting possibilities.The recent Printing from the Linux command line post covers printing in double-sided and portrait mode. In this post, we'll look at printing: Multiple pages per sheet Specific pages or page ranges Pages with borders Multiple copies [ Two-Minute Linux Tips: Learn how to master a host of Linux commands in these 2-minute video tutorials ] How to print multiple pages per sheet With lp, you can print as many as 16 pages of a document on one side of a single sheet of paper. To specify the number of pages to print on a page, use the  lp -o number-up=# command (e.g.,  lp -o number-up=16 mydoc). If your document doesn't contain as many pages as you've requested in the layout, that's OK. The page will simply have an empty area.To read this article in full, please click here

BrandPost: Digital Transformation Update: Challenges & the Road Ahead

Fast, faster, fastest. The pace for digital transformation has escalated such that, if your company hasn’t started, it will be left behind in a legacy bubble, according to participants in a recent IDG TechTalk Twitter chat. A1) I hate to be mean-spirited, but #DigitalDarwinism will take hold at some point if it hasn't already. Regardless of whether your org has been disrupted, your org's sector is a red ocean, or they're just not getting it; the time for lagging is over. #idgtechtalkTo read this article in full, please click here

Grey Failure Lessons Learne

Grey Failures in the Real World

Most “smaller scale” operators probably believe they are not impacted by grey failures, but this is probably not true. Given the law of large numbers, there must be some number of grey failures in some percentage of smaller networks simply because there are so many of them. What is interesting about grey failures is there is so little study in this area; since these errors can exist in a network for years without being discovered, they are difficult to track down and repair, and they are often “fixed” by someone randomly doing things in surrounding systems that end up performing an “unintentional repair” (for instance by resetting some software state through a reboot). It is interesting, then, to see a group of operators collating the grey failures they have seen across a number of larger scale networks.

The Week in Internet News: Russia Moves Toward Test of Internet Disconnect

A separate Internet: The MIT Technology Review looks at the implications of Russia’s test to cut itself off from the rest of the Internet, scheduled for early April. The shutdown is a test of an Internet sovereignty law being considered in Russia, but it’s unclear how the country will actually accomplish the disconnect.

Clamping down: Egypt is cracking down on fake news with new rules that critics say are meant to curb dissent and restrict information the government believe is a threat to national security, The Hill reports. The country’s Supreme Media Regulatory Council can now block websites and some social media accounts with more than 5,000 followers for what it believes is “fake news” and can fine operators up to US$14,400 without getting a court order. Meanwhile, Russian President Vladimir Putin has signed two bills that critics say amount to censorship, Ars Technica says. One bill allows stiff fines for disseminating what the government determines is fake news, and the second allows fines and jail time for insulting government officials, including Putin.

IT needs to make mobile unified communications a priority

The need for safe, reliable, and easy-to-use communications tools has given rise to unified communications (UC), a strategy that integrates multiple communications modalities under a single management and security umbrella. The result is more effective communication, improved collaboration, and a boost to security and regulatory policies. Now that mobility is the primary networking vehicle for end users, it’s time for IT departments to make mobile unified communications (MUC) a priority.The most important benefit of MUC is the ability of organizations to finally leave behind the uncontrolled, untracked mish-mash of consumer-centric, carrier, and third-party communications tools traditionally applied over the years. Communications are a critical organizational resource; MUC is a much easier vehicle to manage and scale, and MUC offers the visibility and control that’s essential to enterprise IT deployments. These advantages will enable MUC to become the dominant provisioning strategy and mechanism for organizational communications over the next five to 10 years.To read this article in full, please click here

Amazon Aurora: design considerations for high throughput cloud-native relational databases

Amazon Aurora: design considerations for high throughput cloud-native relational databases Verbitski et al., SIGMOD’17

Werner Vogels recently published a blog post describing Amazon Aurora as their fastest growing service ever. That post provides a high level overview of Aurora and then links to two SIGMOD papers for further details. Also of note is the recent announcement of Aurora serverless. So the plan for this week on The Morning Paper is to cover both of these Aurora papers and then look at Calvin, which underpins FaunaDB.

Say you’re AWS, and the task in hand is to take an existing relational database (MySQL) and retrofit it to work well in a cloud-native environment. Where do you start? What are the key design considerations and how can you accommodate them? These are the questions our first paper digs into. (Note that Aurora supports PostgreSQL as well these days).

Here’s the starting point:

In modern distributed cloud services, resilience and scalability are increasingly achieved by decoupling compute from storage and by replicating storage across multiple nodes. Doing so lets us handle operations such as replacing misbehaving or unreachable hosts, adding replicas, failing over from a writer to a replica, scaling the size Continue reading
