Running Oracle EBS in the cloud (UKOUG Apps16) － successor
https://www.slideshare.net/AndrejsProkopjevs/running-oracle-ebs-in-the-cloud-oaug-collaborate-18-edition
Less technical deep-dive. More comparison, know-hows, and the process.
We will be agnostic to cloud platform vendors.

What is
happening in 2022

What is New in 2022
In the last 5 years, it is still …
● Possible mix of IaaS, PaaS, and SaaS, depending on the platform chosen.
● Continuous client-demanding topic.
● Uncertainties around the options.
In the last 5 years, we have got …
● All cloud platforms are similar from an infrastructure point of view (in general).
● Oracle Cloud improved and stabilized. Numerous EBS-centric integrations matured.
● Oracle introduced a licensing trap running its software on non-OCI cloud platforms.

Support for EBS workloads
● Oracle Cloud (OCI)
● Amazon Web Services (AWS)
● Microsoft Azure (Azure)
● Google Cloud (GCP)
○ Supported only on Bare Metal Solution.
● VMware Cloud services
○ Available and not limited to platforms listed.
○ No certification (VMware KB and Doc ID 249212.1).
○ Licensing - Host Affinity and CPU Affinity.
○ Features like Real Application Cluster (RAC) are
supported only for on-premises.

Our Focus
● Amazon Web Services (AWS)
● Microsoft Azure (Azure)
● Google Cloud (GCP)
○ Supported only on Bare Metal Solution.
● VMware Cloud services
○ Available and not limited to platforms listed.
○ No certification (VMware KB and Doc ID 249212.1).
○ Licensing - Host Affinity and CPU Affinity.
○ Features like Real Application Cluster (RAC) are
supported only for on-premises.
Google Cloud BMS or VMware
1. a special condition
2. more comprehensive capacity
pool planning
3. direct involvement of platform
sales negotiating the pricing.

Network
Region and Availability Zones
● Features and compute capacity
● High Availability
● Network latency with your intranet
● Data protection or privacy legislation requirements
Security
● Protected private subnets (expose only what is required)
○ Load Balancers
○ Proxy servers
■ HTTP (reverse and forward)
■ Interface file exchange bridges
■ Secure tunnels
○ SQL*Net Connection Manager (CMAN)
○ Bastion hosts
Everything should start with a proper and secure network design.

Instances (virtual machines)
● General purpose
● Compute-optimized
● Memory-optimized
● Storage-optimized
● Accelerated computing
● Flex shapes (OCI feature)
○ General hardware specifications.
○ Choose your own compute power parameters.
The throughput limits scale together with the CPU
allocation selection.
Different IO and network throughput limits
○ It is common to set a more oversized instance type for
the database tier to meet higher throughput performance
criteria.
Pricing
○ On-Demand vs. Reserved Capacity
Dynamic IP addresses
○ A problem for EBS configuration.
■ Link with DNS service.
■ OS correction start-up service (like hosts).
■ Logical hostname configuration.

Storage
● Block storage － general disk volumes assigned to one instance at a time
○ Example: Database data files.
● Local ephemeral non-persistent storage － local disk storage with temporary data being lost during an instance restart
○ Examples:
■ Runtime temporary/lock/pid files.
■ Database Smart Flash Cache feature.
● File system storage － network-based volumes (like NFS) which can be shared between multiple instances
○ Example: Apps Base file system.
● Object storage
○ Examples: Interface file exchange or storing the backups.
SQL> show parameter db_flash_cache
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
db_flash_cache_file string /dev/xvda1
db_flash_cache_size big integer 200G

IO performance
IOPS and IO throughput － the most difficult part.
Limitations per object type:
● instance/shape type or its compute capacity
● storage type or the volume size
● VPUs (OCI feature)
○ Baseline + dynamic scale
○ No data migration is required
The secret is in the details! Experiment and benchmark.
Note: Oracle Database IOPS ≠ cloud storage IOPS
High-Performance
storage
=
higher IO
performance
= $$$$$$$
Combination of an
instance type and
standard storage
=
higher IO
performance
= $$$$$$$
Classic AWS example for DB-tiers
1. Memory-optimized instance type.
(40 GB => 120 GB RAM. Equal vCPUs/licensing)
Higher instance-level throughput limits.
2. 1 x 1 TB io1 disk => 5 x 200 GB gp2 disks
3. ASM with data disk rebalance.
Result: Same throughput performance metrics.

Licensing
○ Enterprise Edition
2 OCPUs = 1 processor license
○ OCPU vs. vCPU － core vs. virtual thread
wild comparison: 1 OCPU = 2 vCPUs
● Oracle Authorized Cloud Environments －
Amazon Web Services (AWS)
Microsoft Azure (Azure)
○ Enterprise Edition
2 vCPUs = 1 processor license
○ without hyperthreading enabled
1 vCPU = 1 processor license
○ Oracle Processor Core Factor Table
does not apply !!!
Important note: The above licensing outline is based on Oracle's general materials and licensing terms.

Pros & Cons highlights known by Pythian - OCI
Pros
● Native cloud platform
● Native integrations with Cloud services
● License-included models
● Optimal licensing costs
● Infrastructure:
○ OCPU (physical core) vs. vCPU (virtual thread)
○ Flex shapes
○ VPUs and Dynamic Performance Scaling for storage
● Managed Database Services:
○ DB-tier RAC option support with shared block storage
○ Exadata for the highest IO performance
● Lift & Shift process automation tools
● EBS Cloud Manager with automation options
Cons
● OCI console stability is often frustrating.
● The Cloud Lift service may not cover all prerequisites.
○ Foundational architecture investment is required.
(IAM, Security, Infrastructure-as-Code, etc.)
● DBaaS management (DBCS or ExaCS)
is not as seamless as Oracle may present.
○ DBAs still spend time working with Oracle Support.
Resource savings marketed are likely not achievable.
● EBS Cloud Manager:
○ Discovery feature － only recently supported.
○ Automation scenarios may not achieve all the requirements.
Or simply do not work.
● OCI Universal Credits “sold” by Oracle:
○ Customers will always pay at least that much.
Test a lower capacity with a Pay-as-you-Go model.
● Infrastructure Compute (IaaS) － more scalable storage
opportunities than Managed DB service (DBCS).

Pros & Cons highlights known by Pythian - AWS
Pros
● The most-popular Cloud platform on the market
● Good proven stability (experience)
● User-friendly management interface (subjective)
○ Except tagging nightmare 🙂
● Wide range of implementation possibilities
● Various storage options and backup
● Next-gen instance types － faster and easier switch
● Longer tolerance to legacy platform requirements
Cons
● Expensive licensing
● Significant data transfer rates
● Higher Cloud operational costs (in general)
● No ready templates are available for easy provisioning
● You are responsible for instance/database lifecycle
● Not many automation options are available for Oracle
○ Nothing for Oracle EBS
● High-Availability － manual setup
○ Based on the on-premises principles
● No support for database RAC option

Pros & Cons highlights known by Pythian - Azure
Pros
● Good choice for Microsoft-centric organizations
● Modern storage/backup solutions
● Good cooperation with Oracle
○ Oracle DB VM templates for easy provisioning
○ Direct-Link with OCI regions (depends on the region)
○ Oracle is testing its products on Azure
● Rich marketplace (integrations)
Cons
● Expensive licensing
● No EBS templates are available for easy provisioning
● You are responsible for instance/database lifecycle
● Not many automation options are available for Oracle
○ Nothing for Oracle EBS
● High-Availability － manual setup
○ Based on the on-premises principles
● No support for database RAC option
● Careful region/zone and VM size decisions

Pros & Cons highlights known by Pythian - Other notes
High-Availability for EBS
● Manual setup and process － common practice.
○ OCI EBS Cloud Manager － advantage but far from perfect and not easily usable.
Miss of the DB RAC option on non-Oracle cloud platforms
● Additional same-region DR with Data Guard. Or Active Data Guard as read-replica.
○ Doubles the storage cost.
● Less critical systems － additional DB-tier VM on standby.
○ OS software failure － reassign DB storage volumes and restart (< 1 hour downtime).
● Third-party solutions like FlashGrid or VMware.
○ Decision risk － not supported by Oracle.

The migration
process

First steps
Q: What is the capacity we need to estimate for the cloud move?
Evaluate your current performance !!!

Proof of concept
● Migrate first in a lower test capacity.
○ Evaluate the performance and compare it with the baseline requirements.
○ Recent compute generations may be faster and cheaper.
○ Right-size the compute requirements based on the utilization statistics.
● Automation.
● Evaluate the native cloud lift services (if available).
○ It may not cover all the prerequisites.
● Design and confirm your integration strategy.
○ Usually, it is the area with all the surprises and technical challenges.

Downtime planning
Well-established process and planning are important !!!
● Proof-of-concept migration, Testing.
● Pre-production built and its pre-migration validation.
○ Re-use the infrastructure and its configuration as part of the production migration.
● Leverage the physical standby switchover model.
○ 30 min - Standby switchover (physical).
○ 60 min - EBS stack reconfiguration (if no logical hostnames are in use).
○ 30 min - Frontend access switchover and/or DNS updates.
○ 120 min - Interface switchover (with pre-built and verified targets and configuration during the pre-production
iteration). Note that this number can be even less.
4 hour downtime
(general example)
300 GB or 12 TB system

Summary
(the key highlights)

Positive benefits of moving to the cloud
● We move off from the aging on-premises hardware.
● Long-term deployment:
○ Server OS lifecycle terms only. No hardware dependency.
● Ability to right-size the capacity and avoid over-provisioning.
● Rapid scaling per requirements.
● Rapid provisioning per development project requirements.
● Automation options:
○ Control the non-production instance availability during business hours.
○ One-click instance refresh for non-production.
○ Automated DR failover.
○ Other possible scenarios per business requirements.

Negative aspects of moving to the cloud
● Security and Data Protection are critical !!!
○ Secure architecture design is a must on all layers.
○ Encrypt and protect as much as possible.
● Strict access control to all objects and services.
● Mistakes in design will lead to technical debt and risks from day 1.
● Possible network latency with the cloud service provider.
○ Research the closest availability zone options.
● Moving to Cloud is not always cheaper than staying on-premises.
○ Cost evaluation and its governance are important.

How to choose the right platform?
● Existing corporate presence
● Feature requirements
● The region, availability zone, and feature availability
○ Data protection or privacy legislation requirements.
● Cost
○ Experiment and compare.
● Licensing

Key factors of success
● Experiment with lower compute capacities.
○ Right-size the compute requirements based on the utilization statistics.
○ Leverage the dynamic scaling features (as applicable).
● Well plan your migration process.
● Licensing － consult with an Oracle licensing expert.
○ Evaluate and understand all the options that suit your requirements.
○ Choose the most optimal cost.
○ OCI Universal Credits, sometimes, is a trap.

Case study
(basic example)

Let us imagine …
Pythian is running its own Oracle Financials system in its on-premises data center.
Our inputs are:
● Basic single Apps-tier and DB-tier topology.
● DR site with Data Guard.
● Database size: 1.5 TB.
● Utilization: 25 %.
● Data must locate in Canada due to legislation requirements.
● Existing AWS cloud presence.

Objectives
We are looking for:
● Compare the features available between OCI, AWS, and Azure.
● Preliminary potential cost comparison.
● Summarize the roadmap recommendations.
Other assumptions:
● Oracle licensing － general BYOL approach.
● Leveraging automation is not a key requirement.
● Cost estimate － current capacity and 50% less CPU/Memory power (underutilization).

Conclusion summary
● OCI is an obvious winner based on the features and the cost.
○ But it requires additional foundational investment and training due to an existing AWS presence.
● AWS, having it as an existing cloud presence, deployment requires at least double the licensing
investment for a similar compute power capacity.
○ Due to the underutilization, the 50% capacity reduction is real to meet the current BYOL portfolio and the
budget. But it is a loss long-term.
● AWS is not an option due to a single regional availability in Canada.
○ It does not meet the requirements but can play an alternate DR deployment role.

Thank You.
