Dɛn Pɛpɛɛpɛ ne Application Kernel ne Dɛn Nti na Ɛho Hia?

Aplikeshɔn kernel bi te user-space programs ne operating system ntam, na ɛyɛ adwuma sɛ gatekeeper ma system frɛ. Nea ɛnte sɛ OS kernel a edi mũ no, ɛtwe adwene si sandboxing so ketewaa bi — ɛto nea application pɔtee bi betumi anya, asesa, anaa ayɛ no ano hye.

Ɛdenam Rust a wɔpaw so no, Syd adwuma no tew ntua no ani wɔ softwea stack no fã a ɛho hia sen biara no so. Wɔ adwumayɛ nhyehyɛe ahorow a edi sikasɛm ho nsɛm a ɛho hia, adetɔfo kyerɛwtohɔ, ne adwumayɛ nhyehyɛe ho dwuma no, saa adansi ho nhyehyɛe ahorow yi cascade kɔ ahobammɔ mu aba ankasa mu.

Dɛn nti na Rust Rebɛyɛ Kasa a Wɔpaw ma Ahobanbɔ-Ahobammɔ Nneɛma a Ɛho Hia?

Rust a ɛrekɔ soro wɔ systems programming mu no nyɛ akwanhyia. Kasa no hyɛ memory ahobammɔ mu den wɔ bere a wɔboaboa ano a wɔmfa wɔn ho nto nwura a wɔboaboa ano so, na ɛma ɛfata soronko ma mmara a ɛfa adwumayɛ ho, a ɛho hia ahobammɔ. Syd adwuma no kyerɛ Rust mfasoɔ dodoɔ bi a ɛfa adwumayɛkuo softwea nkɔsoɔ ho kɛseɛ:

Ɔkwan Bɛn so na Syd's Architecture Nkyerɛ aseɛ kɔ Adwumayɛ Software Ahobanbɔ mu?

Nsɛmmisa a Wɔtaa Bisa

Dɛn ne Syd na ɔhaw bɛn na ɛdi ho dwuma?

Syd yɛ Rust-based application kernel a wɔayɛ ama sandboxing dwumadie a wɔnnye nni wɔ Linux nhyehyɛeɛ so. Ɛsiw system frɛ ahorow ano de hyɛ ahobammɔ ho nhyehyɛe ahorow mu den, na ɛmma application ahorow ntumi nkɔ fael ahorow a wɔmma ho kwan, network ahode, anaa system ahoɔden ahorow mu. Ɛdenam ahobammɔ a ɛho hia yi a wɔde bedi dwuma wɔ Rust mu sen sɛ wɔde bedi dwuma wɔ C mu so no, Syd yi memory-safety mmerɛwyɛ ahorow a abakɔsɛm mu no na ɛyɛ ntua titiriw a ɛde ba sandboxing nnwinnade so no fi hɔ.

So ɛhia sɛ mehu Rust na ama mate application kernel adwene ase?

Dabi. Bere a Syd dwumadie no yɛ Rust-specific no, adwene a ɛwɔ aseɛ — nhyehyɛeɛ frɛ interception, process isolation, least-privilege enforcement, ne security policy management — yɛ kasa-agnostic. Video no kyerɛkyerɛ nnyinasosɛm ahorow yi mu wɔ ɔkwan bi so a ɛbɛboa developer anaa mfiridwuma kannifo biara a ɔdwen software ahobammɔ ho, a wɔn programming kasa titiriw mfa ho.

Ɔkwan bɛn so na saa ahobanbɔ ho adwene a ɛba fam yi fa SaaS adwumayɛ nhyehyɛe ahorow ho?

Nnyinasosɛm biara a wɔada no adi wɔ Syd mu no trɛw kɔ application-level ahobammɔ so. Process isolation maps to tenant isolation wɔ multi-tenant platforms so. System call filtering ne API abisadeɛ a wɔgye tom ne kwan a wɔde hyɛ mu no di nsɛ. Defense-in-depth strategy a wɔada no adi wɔ video no mu no yɛ sɛnea platforms te sɛ Mewayz bɔ adwumayɛ ho data a ɛho hia ho ban wɔ module ahorow a ɛfa sikasɛm, adwumayɛ, nnipa ahoɔden, ne adetɔfo sohwɛ ho — hwɛ hu sɛ obiara a ɔde di dwuma, kuw, ne ahyehyɛde no nya nea wɔama wɔn tumi sɛ wonhu nkutoo.
