This would be a good time to ask about how many are familiar with Docker itself before we delve too much into the Cloud service.
Benefits of Docker
• Lightweight
• Walled off from other process
• Repeatable

When people talk about docker it's not just the engine it could be many parts of the ecosystem. However we are only going to go in to various aspects of it as we go.

Oracle has been putting more services into their cloud portfolio, but how well does it work.well to start docker offers a lot of in terms of being lightweight and

Before we see how everything works lets talk some number real quick.
Cost
CC BY 3.0 US, Harold A. Dost III 12
Compute Structure
• Product (per OCPU) comparable to 2 AWS vCPU basically 1 thread of core

Star means coming soon
Compute Structure 3
• Standard | High Memory
• OC1* - 0.25/1.8 | N/A
• OC2* - 0.5/3.75 | N/A
• OC3 - 1/7.5 | OC1M 1/15
• OC4 - 2/15 | OC2M 2/30
• OC5 - 4/30 | OC3M 4/60
• OC6 - 8/60 | OC4M 8/120
• OC7 - 16/120 | OC5M 16/240

Cost - Metered
• General Purpose Compute (Price Per OCPU)
• $0.1344/Hour $112.90/Month $1174.12/Year
CC BY 3.0 US, Harold A. Dost III 15
Cost - Non metered
• General Purpose Compute
• $75.00 /Hosted Environment (Minimum 2)/Month
CC BY 3.0 US, Harold A. Dost III 16
Comparing To AWS• Has service called (Elastic Container Service)
ECS
• No additional for Compute Resources
• However ELB used for service discovery costs about $18/month/Load Balancer

Docker Compatible

Ultimately this a function of the
Multi-Host Applications
CC BY 3.0 US, Harold A. Dost III 21
Service Scaling
CC BY 3.0 US, Harold A. Dost III 22
CI/CD Pipeline 9
• Not really anything differentiating
• Can be done with any Docker instance

Intuitive Interface
CC BY 3.0 US, Harold A. Dost III 24
Operational Dashboards
CC BY 3.0 US, Harold A. Dost III 25
Having port checking and load monitoring are definite good services to include
Health Checks
• Definite benefit, but almost expected at this point.
CC BY 3.0 US, Harold A. Dost III 26
Control Placement Policies
• Underlying technology certainly
CC BY 3.0 US, Harold A. Dost III 27
Resource Pools
CC BY 3.0 US, Harold A. Dost III 28
Not going to go into a diatribe however, yes one you get all of your configurations setup and working
One Click Deploy
CC BY 3.0 US, Harold A. Dost III 29
How ever I do believe that they were targetting the trend towards so called infrastructure as code. Allow for more repeatable configurations.
Best Practices Included• In marketing this doesn't really do much for
me.
• "Best" is generally up to interpretation.

Using application from another presentation
Quick App Demo• How to deploy an application on Container
Service.

ConclusionGood• Provides a relatively good experience over all.
• Much of this functionality provided by docker itself.
• Additional services are nice and seem to work well.
CC BY 3.0 US, Harold A. Dost III 32
Bad• Barrier to entry.
• Ill defined differentiators.
CC BY 3.0 US, Harold A. Dost III 33
Ugly• Nothing particularly jaw dropping.
