Enterprise storage requirements

• Requires consistent performance, each application has unique requirements

• Addressed by storage layers like SSD, SAN, NAS etc..Performance

• Addressed by using RAID, Disk Backups, Tape BackupsDurability and availability

• Requires high CAPEXCost

• Often addressed by over provisioningElasticity and scalability

• Requires consistent performance; each application has unique requirements

• Addressed by storage layers like SSD, SAN, NAS, etc..

• Addressed by using RAID, disk backups, tape backups

• Requires high CAPEX

• Often addressed by over-provisioning

Enterprise storage on AWS

• Requires consistent performance, each application has unique requirements

• Addressed by storage layers like SSD, SAN, NAS etc..Performance

• Addressed by using RAID, Disk Backups, Tape BackupsDurability and availability

• Requires high CAPEXCost

• Often addressed by over provisioningElasticity and scalability

• Provisioned IOPS, SSD, Amazon Elastic Block Store (Amazon EBS) Optimized Instances

• Built in replication across AZ; snapshots can be replicated across regions

• Pay for what you use, buy vs. build

• Use as little or as much as you want or need

EBS snapshots enabled

Data files PIOPS—EBS

volumes

Striped across multiple volumes using ASM or any

other technology

PIOPS of 1000 or above

Redo log files PIOPS—EBS

Use separate EBS volumes for each group

Preferable to use ASM disk groups

Archive log

EBS volumes Standard volumes for normal database workloads

PIOPS for highly transactional environments

Standard EBS volumes for local backups

Use OSB / other technology to push to Amazon S3
