There’s finally a communication app tailormade for on-the-go teams. Try it free.

One of the hardest things for employers to do is keep up with the needs of an increasingly mobile workforce. More than ever, teams are using multiple devices to do their work on the go — and for workforces that are dispersed, it can be difficult to get on the same page for key objectives and initiatives. That’s where Eko comes in: this performance-boosting platform is built for mobile workforces, combining communications, process management, task management, e-learning and HR functionalities into one easy-to-use app. Ideal for remote teams, retail and hospitality, this app streamlines everything frontline staff needs to be successful into one helpful tool. To read this article in full, please click here

Service Mesh: The Next Step in Networking for Modern Applications

By Bruce Davie, CTO, Asia Pacific & Japan

What’s New in the World of Networking

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

Getting help for Linux shell built-ins

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

BrandPost: Digital Transformation: Can SD-WAN Help Strengthen Application Security in a Cloud-First World?

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

3 Tools for Getting VMs From Your Datacenter to the AWS Cloud

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

Network Break 244: IBM, AT&T Play Cloud Footsie; Oracle Tries To Force-Choke AWS Over JEDI Contract

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.

The Week in Internet News: Community Broadband Offers Fastest Speeds in U.S.

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

AT&T partners with IBM and Microsoft, focuses on network capabilities

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

Sudden Explosion of Data Centers in India

 

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
