A few days ago Microsoft introduced its new operating system designed for IoT devices: Azure Sphere OS. The new operating system aims at providing a secure-by-default platform to build IoT services and thus avoiding the pitfalls that made such devices so prone even to unsophisticated attacks that rogue organizations use them to build botnets or to compromise users’ privacy.
The new OS
Azure Sphere is just a part of a broader solution to provide a secure platform for IoT that also includes custom microcontrollers that implement Microsoft 7 rules for IoT security and a security service that runs on Azure to verify the status of each device and report any error or [...]
We recently had a problem on a server since one of its services was randomly experiencing spikes in CPU load that required restarting the service. Such event was happening once in a while and only required a restart. While we were tracking the problem down, we needed a temporary solution that didn’t require us to manually restart the service. Luckily Powershell came to the rescue with a simple script:$interval = 30 #seconds $counterSample = Get-Counter '\Processor(_Total)\% Processor Time' -SampleInterval $interval $avgLoad = $counterSample.CounterSamples.CookedValue Write-Output "Average CPU load : $avgLoad"
The tricky thing is that we didn’t want to measure [...]
Già dal 2012, con l’introduzione di Windows Server 2012, Microsoft ha presentato ReFS (Resilient File System), un nuovo file system per gli ambienti Windows progettato per i workload moderni e, idealmente, per sostituire NTFS appena possibile. Le prime versioni di ReFS non brillavano per velocità ma con Windows Server 2016 ReFS è diventato il file system raccomandato per workload importanti come i cluster di storage S2D o per le infrastrutture iperconvergenti basate su Hyper-V, promuovendolo ormai senza riserve all’uso in produzione.
Nel mondo di Windows Server è certamente inusuale discutere di file-system alternativi a NTFS, discussioni più comuni nel mondo Linux [...]
