The Top 5 Reasons to Use an Oracle Database
1 Flexible Standards
2 Scale-on-Demand
3 Highest Availability
4 Cost & Consolidation
5 Secure Future

2 Scale-on-Demand
5 Secure Future

Flexible Based on Strong Fundamentals
Structured Query Language
(SQL)
Oracle supports ANSI standard
SQL
Has extensions to the SQL
language for features that are
not included in ANSI standard.
Multiversion
Read Consistency
The data returned by a query is
committed and consistent for a
single point in time.
Nonblocking queries
Readers and writers of data do
not block one another.
Non-escalating
row level locking
Transactions
Supporting transactions means
the database ensures A.C.I.D.

• Oracle Multitenant means self-contained,
Pluggable Databases (PDBs) providing
- Rapid deployment with Hot Clone
- Refresh / incremental refresh
- Relocation with no downtime
- PDB upgrades (using plug / unplug)
• PDBs enable transparent, simplified online
lifecycle operations for any application
• PDBs speed up database migration to
new container databases (in the cloud)

Architecture for database consolidation & optimized lifecycle operations

Pricing Retail
CRM

Converged Database
Use cases are converging
Phone calls, messaging, photos, etc.
originally required separate products
• Now they are features of Smartphones
Similarly, ML, JSON, Blockchain, etc.
originally required separate databases
• Now they are features of a Converged Database

Use Cases are Converging for Good Reasons
Developers innovate faster with converged
It is dramatically simpler for developers to invoke extended SQL to execute ML, graph, spatial,
blockchain, IoT, etc. in one converged database
Instead of implementing distributed execution and data movement across multiple
fragmented databases

horizontal scaling
Scale-on-Demand with Oracle – Always the Right Size
Single Instance
Oracle Database
online vertical scaling
(Single Instance) Database
with Oracle Sharding
linear horizontal scaling for
sharding-aware applications

Linear Scalability
Add shards online to increase
database size and throughput.
Online split and rebalance.
Extreme Availability
Shared-nothing hardware
architecture. Fault of one shard
has no impact on others.
Geographic Distribution
User defined data placement for
performance, availability, DR or to
meet regulatory requirements.
…

Some large scale applications want to shard data across independent databases and are willing
to modify the application to do so and for getting the benefits listed above.

Application Continuity
Protect your applications from any interruption
Application outage protection
• For planned & unplanned outages
• System outage protection alone does not
ensure applications are uninterrupted
• Application Continuity continues reads
and replays in-flight database requests
• 100% transparent to the users and
applications – fully automatic
• Unique to Oracle!
• Available with Oracle RAC and Active Data Guard

Choose the right flavor for your application
Transparent Application
Continuity
works without Oracle pools,

Benefit from Cloud Sizing
All workloads exhibit variation – “normal” to “peak”
• Annual/quarterly/weekly/daily seasonal variations
• Retail/other seasonal transactions,
periodic reports and compliance, full backups
• But also intraday variation
• End-of-day reports, analytics workloads, day/night (e.g., lower daytime workload on
sparsely populated landmasses/Pacific Ocean), incremental backups
• On-premises common to see “peak” sized “2x normal”
• If 16 cores are “normal”, the system may get sized with 32 cores
On cloud, it is safe to provision for normal workloads and burst up as needed

Production Workload Sizing
On-premises, size for the peak,
plus additional buffer = lots of idle CPU

CPU Usage
Normal + Hourly Bursting

Buffer
On the cloud, size for the normal workload,

= no need to add buffer

Add OCPUs (expansion /
burst) for Hybrid DR

Adjust OCPUs for performance testing
