Worth Reading: Is Openstack becoming Trumpstack?

Tired of hearing about Pets vs. Cattle? Most of us are. The underlying concept is important. While OpenStack, and most private and public cloud platforms, is geared towards workloads that have resiliency build into the application, many of the folks in the industry just aren’t there yet. The question comes to OpenStack advocates now: Should we push away potential adopters of the platform because they may have workloads that aren’t entirely appropriate for a typical “cloud” infrastructure? —DiscoPosse

BrandPost: Bringing flexibility to the WAN

MPLS (multi-protocol label switching) VPNs (Virtual Private Network) have long been recognized as a preferred option for dedicated, high performance connectivity over a wide area network (WAN), such as linking data centers or branch offices that require high volume and reliability. Often these MPLS VPNs would use a broadband internet connection, either DSL, Cable or LTE, as a backup option.  It has become more common recently to leverage that broadband for internet offload.  In fact, the broadband internet is also being used as the primary VPN link for many locations and is even being combined with single user remote access options.  Regardless of the use case for the broadband VPN, it uses the IPSec protocol to encrypt the VPN traffic to keep it secure. To read this article in full or to leave a comment, please click here

5 security practices hackers say make their lives harder

Whether they identify as white hats, black hats or something in-between, a majority of hackers agree that no password is safe from them — or the government for that matter. Regardless of where they sit with respect to the law, hackers mostly agree that five key security measures can make it a lot harder to penetrate enterprise networks.At the Black Hat USA 2016 conference in Las Vegas earlier this month, Thycotic, a specialist in privileged account management (PAM) solutions, surveyed more than 250 attendees who self-identified as hackers (respondents remained anonymous). Eighty-four percent of respondents identified as white hat hackers — security researchers that help organizations uncover and remediate vulnerabilities. And 15 percent identified as black hat hackers, who penetrate networks with criminal intent.To read this article in full or to leave a comment, please click here

Wipro has Holmes, Tata Consultancy Services introduced Ignio, Syntel is selling Synbots. HCL Systems calls its Dry Ice. And Infosys is promoting Mana. With traditional IT outsourcing revenue streams at risk to automation, a number of IT service providers are responding by developing their own homegrown systems which are designed to perform routine tasks and operations otherwise performed by humans.The good news is that CIOs now have a number of automation options to choose from. The bad news? The array of choices can be confusing and the unproven systems can be risky. It may not be immediately clear how these new automation options from traditional IT service providers differ from the solutions of the more well-established robotic systems companies like IPSoft or BluePrism.To read this article in full or to leave a comment, please click here
