38. What is DevOps?
People. Process. Technology
"DevOps is the union of
people, process, and
technology to enable
continuous delivery of
value to your end users."

39. What is DevOps?

40. DevOps Deployment Workflow

41. Terraform – Infrastructure as Code
• Describe configuration in a simple and
constant way
• Version Control your infrastructure
(Firewall Rules, Security Policies, and
configurations)
• Configure network and security
features on cloud providers
• Include Cloud Infrastructure
components as part of a "DevOps"
Pipeline

42. Example Pipeline
• AWS VPN is connected to an "on-premise" Palo Alto FW appliance
• Access control from the AWS Cloud to an On-Premise or customer datacenter application,
configuration can be managed along with changes in the AWS cloud,
• In this case an AWS (SG) security group configuration is in-line with the Palo Alto security
configuration.
• Pan-OS can be configured vi API (Terraform provider) to respect the same configuration in the cloud

44. Docker CLI Overview
Webapps and Docker
Write Dockerfiles
Create a Docker Build pipeline
Deploy apps to Docker Swarm

62. Container Separation
Dan the Developer
Worries about what’s “Inside the
Container”
- Code
- Libraries
- Package Manager
- Data
All the servers look the same
Oscar the Ops Guy
Worries about what’s
“Outside the Container”
- Logging
- Monitoring
- Networking
All containers work the same way
(Start, Stop, etc)

● How Long has it been
broken?
The Basis of Monitoring

84. ● Docker Stats
● Docker Top
● Docker df
● cAdvisor
● Prometheus
Monitoring Tools

85. • Live container resources
• All containers or single
• Very basic but useful info
Docker Stats

86. Docker Top
● Display running process in a container

87. • Developed by Google
• Real-time Data
• Clean UI
• Exposes Metrics
• Integrates well

89. PrometheusStack

90. Federated Configuration

91. • Start small & increment
• Don’t Overlert yourself
• Set Resource Limits
• Aim for actionable Information
• Run separate from Workload
• Test for Failures
• Know your Failure Models
