Dɛn ne nested virtualization wɔ AWS so?

Nested virtualization ma wo kwan ma wotumi de hypervisor di dwuma wɔ EC2 nhwɛsoɔ mu, ɛma virtual mfiri tumi wɔ virtual mfiri mu. Eyi ho wɔ mfaso titiriw ma mununkum pii a atwa yɛn ho ahyia a wɔsɔ hwɛ, adwuma a wɔde ayɛ agyapade a wɔde di dwuma, ne hypervisor-level softwea a wɔyɛ a enni hardware a wɔatu ho ama. Mprempren AWS boa eyi wɔ nhwɛso ahorow a wɔapaw so, na ɛma ɛyɛ mmerɛw sɛ wobɛkyekye virtualized architectures a ɛyɛ den tẽẽ wɔ cloud no mu.

AWS nhwɛso ahorow bɛn na ɛboa nested virtualization?

AWS boa nested virtualization titiriw wɔ bare metal ne Nitro-based instances so, a C5, M5, ne R5 mmusua bi ka ho. Afã no de Intel VT-x anaa AMD-V hardware ntrɛwmu a wɔda no adi denam Nitro hypervisor no so di dwuma. Ansa na wobɛhyehyɛ no, hwɛ AWS nkrataa a aba foforo no mu hwɛ sɛ wo mantam no wɔ hɔ anaa.

Dɛn ne nsɛm a wɔtaa de di dwuma ma nested virtualization?

Nneɛma a wɔtaa de di dwuma no bi ne container platforms a wɔde di dwuma te sɛ Docker wɔ VMs mu, multi-hypervisor mpɔtam a wɔsɔ hwɛ, CI/CD pipelines a ɛhwehwɛ sɛ VM tew ne ho koraa, ne ahobanbɔ nhwehwɛmu a ɛfa sandboxed operating systems ho.

So nested virtualization nya adwumayɛ so nkɛntɛnso wɔ AWS so?

Yiw, nested virtualization de adwumayɛ so ka bi ba efisɛ guest hypervisor no de nkyerɛase layer foforo ka ho ma CPU, memory, ne I/O adwumayɛ. Mpɛn pii no, sika a wɔde tua ho ka no fi 5–15% a egyina adwuma no su so. AWS Nitro nhwɛsoɔ no brɛ saa nkɛntɛnsoɔ yi ase denam hardware-aboa virtualization so.
