Webinar: Linux Kernel Live Patching in VMware Cloud on AWS

VMware webinar banner for email

Organizations use services like VMware Cloud on AWS to deploy hybrid cloud service stacks and data centres. Its familiar vSphere operating environment makes it easy to migrate mission-critical services and applications. Building them on Linux yields versatility and a high ROI, but security and availability are harder to get. That’s because the Linux kernel needs constant patching, and that means downtime and waiting for reboot cycles. Live patching is a way of updating Linux kernels without stopping or restarting them.

Our upcoming webinar will explain what live patching is, how KernelCare does it, and how the technology fits neatly into the VMware Cloud on AWS operating ethic.

Which Configuration Management (CM) Tool to Use? Focus on SaltStack

Which Configuration Management (CM) Tool Should I Use? Spotlight on SaltStack title, saltstack logo, kernelcare logo

The widespread cloud migration of the past decade, and the attendant proliferation of VMs and containers, has made managing machines more complex than ever. DevOps professionals now have to run hundreds if not thousands of machines at once. To help them do their job, Configuration Management (CM) tools have been created. Through a process known as infrastructure as code (IaC) – where an IT environment is declared via a programming language – these allow DevOps teams to keep visibility into their server fleet, and deploy and take action at a mass scale. CM tools facilitate the execution of tasks on multiple servers at once, and one-click app deployment.

The rise of DevOps has necessitated the creation of tools that enable engineers to manage hundreds or even thousands of machines at once. Through a process known as infrastructure as code (IaC) – where an IT environment is declared via a programming language – Configuration Management (CM) tools allow SysAdmins and DevOps teams to maintain visibility over their server infrastructure, and deploy and take action at a mass scale. CM tools facilitate the execution of tasks on multiple servers at once, and one-click app deployment.

Which Configuration Management Tool Should I Use? Spotlight on Ansible

Ansible social post

IT infrastructure is moving to the cloud; VMs and containers are proliferating. There is a constant uptick in the amount of live applications, and all of them are hosted on servers. Today’s SysAdmins and DevOps teams have to manage a huge amount of servers; far more than they did even a few years ago.

As you may know, KernelCare have been live patching Linux kernels on Arm architectures for a while now. But we’re not done spreading the word about live patching Arm-based equipment. To further share our expertise in rebootless Linux kernel updates, we are attending the Arm TechCon 2019, in San Jose, on October 8 – 10, 2019, at the San Jose Convention Center.

Which Configuration Management Tool Should I Use? Spotlight on Puppet

pl social post FB

Back in the nineties and early noughties, enterprises didn’t have to juggle too many servers. The rise of cloud computing has changed all that. Technologies like virtualization and containers now mean that the typical infrastructure is composed of many servers, hosting many applications.

As always, a sharp increase in scale makes it hard to maintain visibility and control. With the proliferation of servers within enterprise infrastructures, apps have sprung up to help IT professionals cope. These are usually referred to as Configuration Management (CM) or Remote Execution (RE) tools. These tools enable a process called infrastructure as code (IaC), in which an IT environment is represented via a programming language, and the tool automates the actions necessary to match the environment to this state. This can include actions like installing software, adding users, or partitioning storage devices.

There are four big players in this space: Puppet, Ansible, Chef, and SaltStack. Here’s a deep-dive into Puppet, the most popular option, which can be used for KernelCare mass deployment.

Silex’s IoT Damage Shows the Need for Live Kernel Patching

Silex's IoT Damage Shows the Need for Live Kernel Patching

In the last week of June 2019, a new type of malware emerged, dubbed “Silex.” Reminiscent of the BrickerBot malware of 2017, Silex went after IoT devices, and killed the operating systems of thousands of devices in a matter of hours. Silex was able to infect any system running a Linux distribution, and chiefly damaged smart thermostats, lights, and sensors.
