Worth Reading: Stream Processing’s Hard Problems

Before we dive into why data access is a hard problem in stream processing, here is some background information. At LinkedIn, we develop and use Apache Samza as our stream processing framework, Apache Kafka as our durable pub-sub messaging pipe, and Databus (and its next generation replacement) for capturing change events from our databases. Our streams infrastructure team gets feedback from application developers across the company (and from the open source community) on scalability, reliability, usability, and other problems that they encounter in their production applications. —LinkedIn Engineering Blog

IDG Contributor Network: ExtraHop integrates into VMware’s cloud management platform

While it would be easy reading the headlines to assume that every organization under the sun is fully committed to the public cloud, the fact of the matter is that public cloud adoption—albeit massive and growing fast—is still the tip of the IT iceberg. For every few million dollars spent on public cloud infrastructure, there are hundreds and hundreds of millions spent on more traditional ways of delivering IT.Which is where a company such as VMware comes in. VMware, which popularized the notion of virtualization—or creating multiple virtual servers on a single physical box—is often criticized (by me, as well) for being somewhat slow to innovate and really embrace the cloud world. But it's not quite so simple as that—VMware has thousands of customers, huge market share and great existing revenues. It needs to move at an appropriate speed for all of these different stakeholders.To read this article in full or to leave a comment, please click here

A Shiny New Way to Manage VMware Guests

Ansible

Way back in March of 2015, I wrote a post about managing VMware guests with the vsphere_guest module. A lot has changed since then with VMware support, including a whole bunch of new modules for managing the VMware infrastructure itself. We've also consolidated all VMware interaction around the pyvmomi Python library, replacing the aging and no longer maintained pysphere and psphere libraries. This support even extends to the VMware dynamic inventory, you will be pleased to know!

We took the opportunity to tidy up some of the parameters used in the old vsphere_guest module, and I think the new vmware_guest module is nicer to use. A couple of handy new additional parameters are validate_certs and wait_for_ip_address. I'm sure they don't need explaining, but for the sake of clarity they allow you to connect to vCentre servers that have a self signed SSL certificate, and for the module to wait for an IP address to become visible for the new VM.

This latter parameter is especially nice, because now you can have the single module wait for the IP address, instead of having to do something clunky with a block (as I did in my main demo).

So here is Continue reading

Cloud giveth and cloud taketh away: Rackspace edition

Hosting firm Rackspace has been a well-known name in the cloud industry for a long time, but lately the company has been struggling to keep up in the core cloud computing competition.Instead, the firm has concentrated on becoming the “#1 managed cloud company,” mixing its own hosting services and cloud offerings while also cutting deals to provide “fanatical” service and support to users of market leaders like Amazon Web Services and Microsoft Azure.It seems that strategy wasn’t enough, at least not by itself.Even as AWS, Azure and Google Cloud Platform have been posting quarter after quarter of amazing growth that help cement their economies of scale, Rackspace’s stock stumbled, (the company had lost half of its market value before talk of a possible sale) which constrained its ability to find a better market position.To read this article in full or to leave a comment, please click here

IDG Contributor Network: Digify for Gmail: Mission Impossible for your email attachments

File sharing and the control over the data within file sharing sits on a continuum. On one end are the consumer offerings that are incredibly easy to use and come with enough, but not too much, functionality. That is the world Box, Dropbox and Google started with. And while these vendors have been moving towards higher-level features, it's fair to say that their start was in the ease-of-use court. At the other end, we have the solutions that are enterprise-focused. These solutions tend towards big, heavy, monolithic structures and myriad levels of control. They're all about ticking the boxes for enterprise security departments, and while they're certainly robust, they're not exactly known for user-friendliness. Indeed, the so-called "Dropbox problem" where enterprises see high levels of nonmandated solution use, came about largely because enterprise solutions are often so awful to use.To read this article in full or to leave a comment, please click here

Are InfoSec vendors ‘sowing confusion’ and selling ‘useless’ products?

As a journalist, you know the drill at media briefings. Hosted and paid-for by a vendor, and with speakers from the company - as well as (usually) an end-user or an academic, the idea is to bring journalists together with the experts to discuss the prominent matters in the industry. And if those issues and industry challenges can be resolved with one of the vendor’s solutions then everyone’s a winner.The vendor gets the business, the press coverage and the thought leadership, while the journalist gets the story, the contacts and the free lunch. The speakers get some media air-time. It’s no surprise then, that these are usually enjoyable, if tame, affairs.To read this article in full or to leave a comment, please click here
