Reading Time: 2 minutesGreenfield and brownfield are terms usually used in factory planning and facilities engineering to describe two different approaches to developing or expanding manufacturing facilities. But they are also used in IT to define different deployment scenarios.

Reading Time: 3 minutesAs you know the VMUG membership is completly free as also most of the benefits, including the online resources, local meeting and UserConf events (some events may have a fee depending by the local VMUG, but almost are for free). But, if you want (and note that it’s not mandatory for VMUG membership), you can have more benefits by subscribing to the VMUG Advantage, that is an interesting way to stay on top of your technical skills with discounts on training, certifications, attendance at VMworld and on product licenses.

Reading Time: 7 minutesTo implement some encryption solutions (like VM encryption, backup encryption, storage encryption) you need to manage symmetric keys in a secure way. Key management has always been solved with proprietary solutions. Each vendor have offered in the past their own key management server/client combination, but as the complexity of datacenters increased, this designed has shown its limits. If you have multiple components, all in need of security keys, why you would need to run multiple key management solutions? But in order to have a common solution, you first would need a protocol to let all […]

Reading Time: 2 minutesSome years ago, I’ve published a post about the Hyperconverged infrastructure market share (2018)… but what about now? How HCI has grow? HCI has become a hot topic with several vendors that aim to be a leader in this area, or with several “magic quadrants” that try to define who is in.

Reading Time: 3 minutesPiù di dieci anni fa avevo scritto un posto su come sia meglio evitare i dischi dinamici di Windows (specialmente Windows Server)… ma a quanto pare c’è ancora chi si ostina ad usarli pensado siano utili e non pensado alle conseguenze. Microsoft Windows Dynamic Disks (chiamati anche Dynamic Volumes) sono un livello di astrazione (introdotto in Windows 2000) sulle partizioni (simile a LVM in ambiente Linux/Unix) per disaccoppiare i volumi (con i relativi dati NTFS) dalle partizioni del disco e avere un maggiore flessibilità, come l’estensione a caldo di un volume semplicemente aggiungendo nuove partizioni […]

Reading Time: < 1 minuteAlso this year Runecast will manage its own event focused this time on security aspects. SecOps 360 Day will be a virtual event bringing together senior security specialists and managers to improve collaboration between IT and security teams – on June 22, 2023.

Reading Time: 4 minutesNot all the different CPUs are the same: they may have a different Instruction Set Architecture (ISA). An Instruction Set Architecture (ISA) is part of the abstract model of a computer that defines how the CPU is controlled by the software. The ISA acts as an interface between the hardware and the software, specifying both what the processor is capable of doing as well as how it gets done. The ISA provides the only way through which a user is able to interact with the hardware. It can be viewed as a programmer’s manual because […]
