It’s recommended to ensure that Security-Enhanced Linux (SELinux) is running in enforcing mode on all your systems. However, some people in your organization may set it to permissive mode (or worse, disabled) rather than troubleshooting and fixing issues.

IT system monitoring is a proactive means of observing systems with the goal of preventing outages and downtime. It involves measuring current behavior against predetermined baselines. Some of the commonly monitored devices are CPU usage, memory usage, network traffic over routers and switches, and application performance, which helps a lot when performing root-cause analysis.

New FinOps for Engineering Training Now Available
FinOps – also called Cloud Financial Management or Cloud Economics – is becoming an increasingly important skill for cloud architects and engineers as adoption of cloud infrastructure accelerates. Which is why the FinOps Foundation has launched a new, online training course, “FinOps for Engineering”, which is a practitioner level course which looks at FinOps from the perspective of engineers. The course is designed to provide engineers and those who architect, design, construct, and operate software solutions and infrastructure in the public cloud to understand how to work effectively with FinOps teams, finance, procurement, product, and management teams to manage cloud use and cost more efficiently and to derive more business value from cloud.
The video-based course covers a variety of important topics for engineers and ops team members, who will walk away with the ability to:
Describe what FinOps or Cloud Financial Management is, why it is necessary, and how it relates to other software engineering methodologies/disciplines
Describe the motivations and drivers of finance, product, business and management teams with respect to FinOps and compare them to engineering and operations groups’ motivations
Understand the fundamental capabilities and functions needed to manage public cloud cost and usage, and the responsibilities of engineering and operations team members in this regard
Explain strategies engineers can take to integrate cost awareness into architecture, design, build and operate processes
Explain strategies for engineering and operations teams to better integrate with other functional groups to derive more value from public cloud use
And more!
Completing this course allows individuals in a large variety of cloud, finance and technology roles to validate their FinOps knowledge and enhance their professional credibility. Enrollment is now open for FinOps for Engineering, and you can learn about our other FinOps training and certification offerings here.

Kubernetes Exam Simulator Available Now to All Those With Valid Eligibilities
We announced the availability of an exam simulator included with the Certified Kubernetes Administrator (CKA), Certified Kubernetes Application Developer (CKAD) and Certified Kubernetes Security Specialist (CKS) exams on June 2nd. At the time we stated that those who purchased any of these exams prior to June 2nd would receive access on a rolling basis; all those holding valid eligibilities for one of the three exams were expected to receive access by mid-August, with those with eligibilities expirining soonest receiving access first.
We are happy to announce that due to the smooth rollout of the new exam simulator, we are able to extend access to everyone sooner than anticipated. Effective immediately, all those who have an unexpired or unused eligibility for any of our Kubernetes certification exams now have access to the exam simulator. To access the simulator, you simply need to log into the training portal and you will see the simulator listed in your exam checklist.
As a reminder, this new perk provides access to two attempts at the exam simulator, provided by Killer.sh. Each attempt grants 36 hours of access starting from the time of activation. The exam simulations include 20-25 questions similar to the ones candidates can expect to encounter on the real exam. The questions presented in the simulator are the same for every attempt and every user, unlike those found on the actual exams, but are still graded to give candidates an idea of how they are performing. The expectation is this offering will help candidates become comfortable and familiar with the environment in which they will sit for their certification.
If you have registered for a Kubernetes certification we encourage you to check out the exam simulator before sitting for your real exam; having this experience will make you more comfortable taking the exam, and may give you a better chance of passing!
