Kafka Wakes Up And Is Metamorphosed Into A Database

Sometimes a database is like a collection of wax tablets that you can stack and sort through to update, and these days, sometimes it is more like a river that has a shape defined by its geography but it is constantly changing and flowing and that flow, more than anything else, defines the information that drives the business. There is no time to persist it, organize it, and then query it.

In this case, embedding a database right in that stream makes good sense, and that is precisely what Confluent, the company that has commercialized Apache Kafka, which is a …

Worth Reading: IoT needs a paradigm shift

Building IoT ventures from scratch by prototyping hardware devices and their backend systems as well as working for a large company that tries to sell IoT devices itself, we learned a lot about the pitfalls and problems concerning security in the IoT. Nearly every connected device out there proved to be vulnerable to attacks. Researchers showed that it’s possible to remotely take control over autonomous vehicles, implanted medical devices were manipulated, voting machines compromised and of course all sorts of other “smart” devices, like door locks, light bulbs, thermostats and the like. In Austria a hotel got threatened by hackers that their guests will be locked out of their rooms, if the hotel doesn’t pay ransom in bitcoins. —Martin Unger @CircleID

Easy data storage services are like fast food

Recently I made the (unfortunate) decision to eat at a particular fast-food establishment. For the sake of this story, let’s call it Shmurger Shming.I didn’t eat at The Shming because the food tastes amazing. Nor did I choose to ingest those Shmurgers because I thought it was, in any way, healthy for me. In fact, I knew full well that eating them would cause not insignificant amounts of gastronomical distress.Which begs the question: Why, on this green Earth, would I make that decision? Why would I do that to myself?Simple. It was convenient, there was very little up-front investment (in time and money), and it was food. Technically. In other words, I was lazy.To read this article in full or to leave a comment, please click here

Cisco’s IWAN isn’t dead

Earlier this month, Cisco completed the acquisition of SD-WAN vendor Viptela, which it had announced in early May.The companies’ recent news sparked several rumors about the fate of Cisco’s Intelligent WAN (IWAN), with publications writing such articles as “Is the End Near for Cisco’s IWAN?” and “Cisco’s Viptela acquisition could mean IWAN is dying or dead.” The content of the articles isn’t quite as aggressive as the headlines, but the articles have led to a number of misconceptions about what Cisco will do with its SD-WAN solution.To read this article in full or to leave a comment, please click here

Connected IoT is about to become cognitive IoT

Connected devices, also known as the Internet of Things (IoT), will transition to cognitive, predictive computing over the next 12 to 18 months, according to research firm Frost & Sullivan. IoT, overall, is also about to grow rapidly, the firm says. It predicts a 20.3% Compound Annual Growth Rate (CAGR) worldwide leading up to the year 2023. That will be a jump to 45.3 billion devices, up from 12.4 billion IoT devices in 2016, it claims.Cognitive computing, which is when a machine is programmed to simulate human thought processes, will partly drive that growth, along with further microelectronics development and “ubiquitous connectivity,” says Frost & Sullivan, a research and consulting firm that specializes in business disruption.To read this article in full or to leave a comment, please click here

A Brief Look at VMware’s Three Cloud Approaches

I’m at VMworld 2017 this week (obviously, based on my tweets and blog posts), and in the general sessions Monday and yesterday VMware made a big deal about how VMware is approaching cloud computing and cloud services. However, as I’ve been talking to other attendees, it’s become clear to me that many people don’t understand the three-pronged approach VMware is taking.

I should start out by saying that this post hasn’t been officially reviewed by VMware (none of my stuff is) and may not align with the “approved” marketing approach, so keep that in mind. This is just me speaking.

As I see it, the three cloud approaches are as follows:

1. Private cloud
2. VMware Cloud on AWS
3. VMware Cloud Services for native cloud workloads

The first option (private cloud) is, I think, pretty much self-explanatory. VMware is offering VMware Cloud Foundation to help streamline some of the infrastructure management in this space, and then the VMware SDDC stack (vSphere, vSAN, and NSX) are layered on top. Couple that with a cloud management platform/automation platform such as OpenStack (VIO would be a good option) or vRealize Automation, and you have a private cloud. (I’m glossing over a few details, but you Continue reading

Automation Tools in Building Network Automation Solutions Online Course

A network engineer interested in attending the Building Network Automation Solutions online course sent me this question:

Does the course cover only Ansible, or does it also cover other automation tools like Python?

The course focuses on how you’d build a network automation solution. Selecting the best tool for the job is obviously one of the major challenges, and so one of the self-study modules describes various automation tools and where you could use them to build a full-blown solution.

ReFS integrity is not on by default

I really don’t like the trend of filesystem authors to only care about filesystem integrity by default. How about having seat belt for your data integrity by default and let people turn it off if they want to compromise correctness for performance?

What I didn’t know is that ReFS integrity is not on by default. Only metadata integrity.

It’s also not visible or changeable in the UI (which is why I assumed they’d done the right thing), which is strange to me, this being Windows. No, you have to drop down into Microsoft’s crappy CLI.

How to check if it’s turned on.

Check files in one directory

PS E:\> Get-Item '*' | Get-FileIntegrity

FileName                       Enabled Enforced
--------                       ------- --------
E:\SomeDirectory               False   True
E:\SomeOtherDirectory          False   True
E:\SomeFile.txt                False   True
[...]

Fuck you, Microsoft.

Check recursively

Of course Get-Item doesn’t do recursion. Why would it? That would make sense.

PS E:\> Get-Children -Recurse 'E:\SomeDirectory' | Get-FileIntegrity

FileName                       Enabled Enforced
--------                       ------- --------
E:\SomeDirectory\foo.txt       False   True
[...]

How to enable it

Both commands are needed. The first command sets the new default for the root directory, and the second adds checksums to all existing files and directories.

PS E:\>  Continue reading

An Inside Look at the Docker Captains Program

Since launching the Docker Captains over a year ago, we’ve received a lot of questions: What is a Docker Captain? What do Captains do? How do I become a Captain? So who better to answer that than the Docker Captains themselves? At DockerCon Austin, we asked the Docker Captains to share their favorite thing about wearing the Captain’s hat.

What is a Captain?

Captains are Docker experts that are leaders in their communities, organizations or ecosystems. As Docker advocates, they are committed to sharing their knowledge and do so every chance they get!

What do Captains do?

Captains are advisors, ambassadors, coders, contributors, creators, tool builders, speakers, mentors, maintainers and super users and are required to be active stewards of Docker in order to remain in the program.

In addition to sharing their knowledge with the community, Captains provide insight and feedback to Docker. They have direct access to our technical teams, and are first to hear about and try upcoming features, product releases and big announcements.

What do Captains get? 

In return for their efforts, Captains get access to the existing captains community and Docker staff. They get ongoing training, private briefings and Slack chat channels where Captains Continue reading
