Linux Will End Up Disabling x86 PTI For AMD Processors.In most desktop-ish workloads, the impact of enabling x86 PTI is much less like with not seeing much of a change for gaming. As outlined in that article, most of the slowdowns attributed to the page table isolation come down to slower I/O but not universally as it largely depends upon the I/O workload as well as the speed of the actual storage device. Yesterday I posted the first benchmarks of the performance impact of these x86 PTI security changes that landed in the Linux 4.15 kernel just days ago. Further Analyzing The Intel CPU “x86 PTI Issue” On More Systems.Note that 4.14.11 also includes the remainder of the kernel page-table isolation patches. The 4.14.11, 4.9.74, 4.4.109, and 3.18.91 stable kernel updates have been released with another set of significant fixes and updates. Thus, it is about breaking down siloed groups of people and responsibilities, and-in their place-building teams that can multitask on technical issues and goals. A successful DevOps strategy requires a merged focus from both development teams and operational teams on what the company needs to meet its digital transformation objectives.

That said, implementing a successful DevOps organization requires IT leaders to think more broadly about how to spur a cultural and organizational shift within both their team and the broader organization, as opposed to simply deploying new technologies.

The promised benefits include increased trust, faster software releases, and the ability to solve critical issues quickly. The concept of DevOps is founded on building a culture of collaboration between IT and business teams, which have historically functioned in relative siloes. The future of DevOps is mastery of multi-cloud environmentsĭevOps is a set of practices that automates the processes between software development and IT teams so they can build, test, and release software more quickly and reliably.Initially Amazon Linux was just an optimized version of Red Hat’s community Fedora Linux, adjusted to work on AWS, but it has evolved over the years. Amazon Linux Moves Beyond the Cloud to On-Premises Deploymentsįor nearly as long as Amazon Web Services (AWS) has been in operation there has been a Amazon Linux operating system that runs on it.While Microsoft leads by overall number of hostnames, it lags in 3rd position when considering the number of unique domains those sites run on, with a total of 22.8 million. This growth was closely followed by nginx, with a gain of 1.09 million domains increasing its total to 47.5 million. It also saw the largest gain this month, increasing its total by 1.53 million. Today, Apache still has the largest market share by number of domains, with 81.4 million giving it a market share of 38.2%. GoDaddy switched back to using IIS 7.5 a few months later. The noticeable spike in Apache-powered domains in May 2013 was caused by the largest hosting company of the time, GoDaddy, switching a large number of its domains from Microsoft IIS to Apache Traffic Server (ATS). There they can use it to run many of the most popular server software programs and technologies, including Microsoft’s Hyper-V, VMware, Oracle’s VM VirtualBox, Docker, and Amazon’s Docker alternative, Amazon Machine Image.

But it’s also making the software available for companies to install on their servers. The new product marks a departure for the cloud-computing juggernaut, as the software can be installed on customers’ servers rather than run from Amazon’s data centers.Īmazon will rent access to Linux 2 to its cloud customers. Last month, soon after Amazon Web Service’s giant tech conference, the company started offering its enterprise customers a new version of the Linux operating system it calls Linux 2.
It’s always a good idea to start a new year with renewed intentions to be even better users and administrators of our Linux systems.
