As I’m currently preparing my breakout session for VMworld 2019, I’ve been spending plenty of time looking into what’s new in the world of networking. A lot of what’s currently happening in networking is driven by the requirements of modern applications, and in that context it’s hard to miss the rise of service mesh. I see service mesh as a novel approach to meeting the networking needs of applications, although there is rather more to it than just networking.
There are about a dozen talks at VMworld this year that either focus on service mesh or at least touch on it – including mine – so I thought it would be timely to comment on why I think this technology has appeared and what it means for networking.
To be clear, there are a lot of different ways to implement a service mesh today, of which Istio – an open-source project started at Google – is probably the most well-known. Indeed some people use Istio as a synonym for service mesh, but the broader use of the term rather than a particular implementation is my Continue reading
Linux built-ins are commands that are built into the shell, much like shelves that are built into a wall. You won’t find them as stand-alone files the way standard Linux commands are stored in /usr/bin and you probably use quite a few of them without ever questioning how they’re different from commands such as ls and pwd.Built-ins are used just like other Linux commands. They are likely to run a bit faster than similar commands that are not part of your shell. Bash built-ins include commands such as alias, export and bg. [ Two-Minute Linux Tips: Learn how to master a host of Linux commands in these 2-minute video tutorials ]
As you might suspect, because built-ins are shell-specific, they won't be supplied with man pages. Ask man to help with bg and you'll see something like this:To read this article in full, please click here
The majority of enterprise CIOs are of in the midst of a digital transformation journey, migrating more of their business applications and infrastructure from their own data centers to the cloud. These applications include real-time voice calling, video conferencing, email, storage, CRM, and many other software applications now delivered as a service – “SaaS.” To support digital transformation initiatives and shifting traffic patterns as more applications move to the cloud, 94 percent1 of enterprises are considering, evaluating or have already deployed1 SD-WAN solutions to address evolving WAN requirements. Enterprises are rethinking their WAN approach to better support multi-cloud infrastructures and to actively leverage higher bandwidth (and often lower cost) broadband services to augment existing MPLS transport networks.To read this article in full, please click here
Here’s a simple scenario: you have some Virtual Machines (VMs) in your on-premises environment, likely in VMware vSphere or Microsoft Hyper-V. You want to either fully migrate some or all of those VMs to the AWS Cloud or you want to copy a gold image to the AWS Cloud so you can launch compute instances from that image. Simple enough.
Now, how do you do it?
Can you just export an OVA of the VM, copy it up, and then boot it? Can you somehow import the VMDK files that hold the VM’s virtual drive contents? Regardless the eventual method, how do you do it at scale for dozens or hundreds of VMs? And lastly, how do you orchestrate the process so that VMs belonging to an application stack are brought over together, as a unit?
This post will answer these questions and more by providing an introduction to the services available on the AWS Cloud to discover, plan, migrate, and track VMs from on-prem to AWS.
This post assumes good working knowledge of technologies such as VMware vCenter and only basic knowledge of AWS.
Let’s just clarify some things first…
Remembering that this post is tailored for those that Continue reading
For the last several years, I’ve organized a brief morning prayer time at VMworld. I didn’t attend the conference last year, but organized a prayer time nevertheless (and was able to join one morning for prayer). This year, now that I’m back at VMware (via the Heptio acquisition) and speaking at the conference, I’d once again like to coordinate a time for believers to meet. So, if you’re a Christian interested in gathering together with other Christians for a brief time of prayer, here are the details.
What: A brief time of prayer
Where: Yerba Buena Gardens behind Moscone North (near the waterfall)
When: Monday 8/26 through Thursday 8/29 at 7:45am (this should give everyone enough time to grab breakfast before keynotes/sessions start at 9am)
Who: All courteous attendees are welcome, but please note this will be a distinctly Christian-focused and Christ-centric activity (note that I encourage believers of other faiths/religions to organize equivalent activities)
Why: To spend a few minutes in prayer over the day, the conference, the attendees, and each other
As in previous years, you don’t need to RSVP or anything like that, although you’re welcome to if you’d like (just hit me up on Twitter).
Hello, May 2019 CCDE Practical exam results announced few days ago. I am happy to help 4 people to have their CCDE number on May 2019 exam. Congrats to Matt , Fredrik , Dmytro and Schilling for passing CCDE Practical exam. They received their numbers! Let me help you to get it now ! Next …
Today's Network Break is all about cloud wheeling and dealing. IBM and AT&T ink a multi-billion cloud deal, but AT&T has also announced a cloud partnership with Microsoft. Oracle looks for ways to get back into the running for a fat Defense Department cloud contract, IBM announces its Q2 financials, and more tech news.

Today, we’re excited to announce the general availability of Docker Enterprise 3.0 – the only desktop-to-cloud enterprise container platform enabling organizations to build and share any application and securely run them anywhere – from hybrid cloud to the edge.
Docker Enterprise 3.0 Demo
Leading up to GA, more than 2,000 people participated in the Docker Enterprise 3.0 public beta program to try it for themselves. We gathered feedback from some of these beta participants to find out what excites them most about the latest iteration of Docker Enterprise. Here are 3 things that customers are excited about and the features that support them:
Simplifying Kubernetes
Kubernetes is a powerful orchestration technology but due to its inherent complexity, many enterprises (including Docker customers) have struggled to realize the full value of Kubernetes on their own. Much of Kubernetes’ perceived complexity stems from a lack of intuitive security and manageability configurations that most enterprises expect and require for production-grade software. We’re addressing this challenge with Docker Kubernetes Service (DKS) – a Certified Kubernetes distribution that is included with Docker Enterprise 3.0. It’s the only offering that integrates Kubernetes from the developer desktop to production servers, with ‘sensible secure Continue reading
Super
fast: ISPs run by local communities or run
through a partnership with a local community offer some of the fastest
broadband in the U.S., a story at Vice.com says. Six of the 10
fastest ISPs in the country are either operated by local communities or are
partnerships between the public and private sectors, according to a PCMag
review.
Conflicting laws: Australia’s recently-passed encryption law, which mandates law enforcement access to encrypted communications, may conflict with the EU’s GDPR and the U.S. CLOUD Act, according to a story at ZDNet. Australian law enforcement agencies may have trouble requiring U.S. and EU companies to decrypt data, the Law Council of Australia has said.
Tweeting is back: The government of Chad has restored access to social media after a 16-month shutdown, QZ.com reports. That’s a lot of missed likes. The government had restricted access to electronic communications for “security reasons” and in “a context of terrorist threats.”
It steals your face: Mobile phone apps that allow you to edit pictures of your face may introduce security vulnerabilities, Forbes notes. One app may upload faces to a database without users’ permission, and another app Continue reading

Earlier this year, AT&T finalized a deal to divest itself of its 31 data centers for $1.1 billion. Now that it has dumped its data center business, the company partnering with two of the largest providers of them: Microsoft and IBM.IBM and AT&T this week announced a multi-year strategic alliance where AT&T’s network and IBM Cloud will link up to provide software-defined network (SDN) services, including giving IBM Cloud access to AT&T’s 5G network. In return, IBM will make AT&T its primary provider of 5G, edge computing, and internet of things (IoT) services and help manage AT&T’s entire infrastructure footprint, including third-party cloud services, using Red Hat’s open-source tools to manage the network. This isn’t really new, as AT&T was using Red Hat Enterprise Linux (RHEL) for some time.To read this article in full, please click here
Something very interesting is happening in the Indian telecom space these days.
The Indian government is considering a new data localisation law that would require all data around Indian citizens to be stored locally, i.e., within Indian borders. It starts with the fintech companies first, and would then bring in the social media and other IOT companies storing data in its ambit. The Reserve Bank of India (RBI) has cheerfully given a deadline to all fintech companies to ensure that the entire data operated by them, is stored in data centers only in India. Ouch.
RBI so far has refused to accept the representations made by the fintech companies to relax the norms. It’s ruled out the option of data mirroring while addressing the arguments of technological hurdles raised by the fintech companies. It’s instead suggested that companies opt for cloud services or private clouds in order to ensure data localization.
So, what’s data localisation? Data localisation is the process localising the citizen’s data to one’s home country for its processing, storage and collection before it goes through the process of being transferred to an international level. It’s done to ensure the country’s data protection and privacy Continue reading
