Amazon Elastic Block Store (EBS) - perekladaiet'sia iak Elastichne blokove skhovishche Amazon, tse posluga, shcho nadaie virtual'ne blokove skhovishche, tobto disk, iakii mozhna priiednati do virtual'nikh serveriv Amazon EC2, a takozh tsia posluga vikoristovuiet'sia Amazon RDS (reliatsiina baza danikh).[1] Tse odin iz dvokh variantiv blokovogo skhovishcha, iaki proponuie AWS, a inshii -- tse EC2 Instance Store.[2] EBS ie komponentom infrastrukturi iak posluga dlia sistem shcho buduiut'sia na Amazon Web Services.
Amazon EBS proponuie shirokii spektr variantiv zberigannia danikh, shcho vidrizniaiut'sia produktivnistiu ta vartistiu. Tsi varianti podiliaiut'sia na dvi kategoriyi
- Zberigannia na osnovi SSD dlia vazhkogo navantazhennia, takogo iak bazi danikh ta tomi z operatsiinoiu sistemoiu dlia zavantazhennia (produktivnist' zalezhit' perevazhno vid IOPS).
- Zberigannia na osnovi gibridnikh zhorstkikh diskiv dlia navantazhen', shcho potrebuiut' menshoyi IOPS, prote mozhut' potrebuvati visokoyi propusknoyi zdatnosti. Tse zadachi iak MapReduce, obrobka zhurnaliv, failiv iaki chasto zminiuiut'sia.
Pri tipovomu vikoristanni EBS matime tablitsiu rozbittia (GPT/MBR), vidformatovano v failovu sistemu, ta failova sistema bude zmontovana. EBS pidtrimuie dodatkovi funktsiyi zberigannia, taki iak snapshot ta klonuvannia. Stanom na veresen' 2020 roku tomi EBS mozhut' mati rozmir do 16 TiB[3].
Tomi EBS pobudovano na vnutrishn'omu skhovishchi, iake maie replikatsiiu. Amazon garantuie shcho vidmova pristroyiv ne prizvede do vtrati danikh. Takii zakhist vid vtrati danikh vidrizniaie poslugu EBS vid EC2 Instance Store
