OCI Architecture

OCI Architecture

1. Regions

2. Availability Domains (AD)

3. Faults Domain

4. MANAGEMENT

   • COMPARTMENT
   • USERS
   • GROUP
   • TENANCY / ROOT COMPARTMENT

5. OCI COMPUTE

   • instances
     • Boot Volume
       • OS disk
     • Block Volume
       • data disk
     • VCN - Virtual Cloud Network
       • Virtual Nic
   • compute
     • Bare Metal
     • Dedicated Virtual Host
     • Virtual Machine
     • PARTS
       • Off-box IO virtualization
       • Storage
     • FUNCTIONS

6. OCI STORAGE

   • BLOCK STORAGE
     • compute istance
       • Remote Attachment
         • iSCSI
           • Paravirtualization ( piu lenta)
           • Oracle DB, Exchange
         • Backup, Snapshot on Object Storage
       • Direct Attachment
         • SSD NVME, denselio
           • no RAID, no SNAPSHOT
             • Big data, OLTP
       • collegato a una sola VM
     • encryption at rest by oracle key
     • BOOT VOLUME
       • creato e cancellato automaticamente
         • encrypted
   • LOCAL NVME
   • OBJECT STORAGE
     • dati generici salvati in Bucket (logical container)
       • API. HTTP
         • • Object storage is replicated across Availability Domains within a region to ensure availability and durability. ENCRYPRION , REDUNDANCY , INTEGRITY.
           • STANDARD OBJECT STORAGE
             • fast acces
           • ARCHIVE STORAGE
             • cheaper
           • OBJECT= type of data
             • BUCKET= logical container
               • NAMESPACE= tenant
         • matadata, automatic indexing
       • UNSTRUCTURED DATA
     • Encryption User Key
   • FILE STORAGE
     • compute istances
       • collegato a una molte VM
         • usa protocollo NFS 3
           • Mount Target // Mount Point
