With a record-breaking 1,300 respondents, the 2015 Future of Open Source Survey results highlight record levels of corporate participation in open source, as well as the greater impact OSS is having on technology and security. Yet, this year's results also reveal a reported lack of formal company policies and processes for consuming and managing open source and its associated legal, operational, and security risks.

O analiza in detaliu a celor mai raspandite platforme de virtualizare (hypervisor, arhitectura, performanta): Hyper-V R2, ESX(i)/vSphere, XenServer si Virtuozzo/OpenVZ.
1. Red Hat Enterprise Linux 6
Red Hat Enterprise Virtualization

2. Virtualizare Integrată
KVM
Beneficiază de facilitățile kernel-ului
Accelerare guest vm
Securitate
Suport Sisteme de operare Windows
Monday, January 24, 2011
3. KVM
Hipervizorul KVM este complet integrat în kernel,
mediul virtual beneficiind astfel de toate îmbunătățirile
sistemului Red Hat Enterprise Linux
• Mediul aplicațiilor este consistent pentru mașini fizice
și virtuale
• Flexibilitate în desfăşurare, prin posibilitatea de a muta
cu uşurinţă clienţi între gazde, permite
administratorilor să consolideze resursele pe mai
puţine maşini (idle times, maintenance)
Veritas IT | Marius Pană

4. Beneficiază de facilitățile kernel-ului
• Scalabilitate crescută de procesoare şi memorie, permite mai multe mașini
virtuale (guest) per server
• I/O scheduler selectabil și suport pentru asynchronous I/O.
• Cgroups și alte controale de resurse pentru CPU, RAM și Networking
îmbunătățesc performanțele sistemului; reduce “resource
contention” (disputa intre resurse)
• Facilități de Reliability, Availability, și Serviceability (RAS)
(Incredere,Disponibilitate,Durabilitate) adaugare de procesoare si memorie
pe sisteme online; machine check handling minimizează downtime-ul
• Multicast bridging include prima versiune de IGMP snooping (in IPv4); build
intelligent packet routing and enhance network efficiency. (cuprinde pachete
inteligente de rutare; crește eficiența retelei)
• CPU affinity - task-urile sunt asignate mașinilor virtuale catre procesoare
specifice
Veritas IT | Marius Pană

5. Accelerare guest VM
CPU masking - permite mașinilor virtuale să folosească același CPU
• SR-IOV - virtualizează resurse fizice, în primul rând networking, permițănd
mai multor mașini virtuale să utilizeze o singură resursă fizică
• Transparent hugepages - performanțe semnificative pentru alocarea de
RAM către o mașină virtuală
• Kernel Same Page (KSM) - permite reutilizarea paginilor identice dintre
mașini virtuale (gândiți deduplicare în contextul de medii de stocare)
• Tickless kernel - definește un model stabil de timp ceea ce evita “clock drift”
• Interfețe paravirtualizate includ dispozitive netradiționale cum ar fi ceasul
(permis de către tickless kernel), interrupt controller, spinlock subsystem,
and vmchannel.

6. Securitate & Suport Microsoft Windows
În medii virtuale, sVirt (powered by SELinux)
protejează mașinile virtuale
• Windows WHQL-certified drivers - oferă posibilitatea
de virtualizare a sistemelor Windows și permit
clienților Microsoft să primeasca suport pentru aceste
instanțe virtuale
