5. What enterprise customers need from a modern cloud
Private connection
Consistent and Predictable Performance
Elasticity and Scalability
High Availability

6. a true enterprise cloud
Oracle Cloud Infrastructure:
Enterprise Workload Migration
Highest, Most Consistent
Performance
Low, Predictable Pricing
a true enterprise cloud

7. Migrating your Oracle Apps to Oracle Cloud Infrastructure
Improve
Superior performance
Fastest, most resilient, full featured Oracle Database
Rapid provisioning and scalable capacity
Move
Expert migration assistance
Automated migration tools
No re-architecture

8. Run Your Whole App Portfolio on Oracle Cloud
Scale-up Apps run better than on-prem
Tight orchestration for scale-up
Predictable app and database low latency
Petabyte-scale database capacity
Scale-out Apps run better than on other clouds
Native orchestration for scale-out
Predictable node-to-node latency
High-performance nodes
Predictable, millisecond latency and 10K’s of IOPS for queries
Oracle Database Cloud
Database on Compute/ Storage
Legacy App on Compute
Oracle App on Compute
Support for custom middleware, OS, hypervisors, network topologies
Support for millions of IOPs and petabyte scale databases
10K’s of calls per second between nodes
Compute/ Storage
Support for millions of IOPs per node
Support for custom Hadoop, Kubernetes, and other scale-out frameworks

9. How Customers Benefit from Moving Apps to The Cloud
Innovation
Transformation
Performance
Cost
Business Outcome
Accelerate business transformation & innovation by getting new apps out quickly
IaaS provides instant access to resources, not infrastructure procurement headaches
Predictable performance supports workloads from cloud-native to mission critical apps and DBs in the Oracle Cloud
Reduce on-premises infrastructure spend and add predictable costs based on usage
IT Outcome
Consolidate Oracle Apps silos with disparate on-premises hardware into a single cloud infrastructure
Focus on strategic priorities, not managing hardware and software
Next generation IaaS performance matches and often exceeds on-premises deployments
Eliminate the hardware refresh and capacity planning vicious cycle

10. Oracle Cloud Infrastructure – Innovation at its Core
High performance compute, storage, database, edge on the same flexible virtual network

13. Performance, usually uptime, for a higher than normal period”
High Availability ?
Assume that every component of a system will
fail at some point and to prepare for that eventuality
How to protect applications from a disaster?
Infrastructure should attend to unpredictable demand
and should always be available to end-clients
“A characteristic of a System, Which aims to ensure an agreed level of operational
Performance, usually uptime, for a higher than normal period”

14. High Availability for Oracle Cloud Infrastructure
Options for High Availability :
Multi-Region
Multi-Availability Domain
Multi Fault Domain .
Region:
Serve different geographies.
Availability Domain:
Fault-decorrelated, completely independent datacenters in metropolitan area
Fault Domain:
Fault Domain provides a higher degree of protection from unexpected hardware failure or planned hardware maintenance using logical grouping of hardware and infrastructure
