Infrastructure of the last century leads to ITSM challenges
© 2016 Ribose. Public.
Multiple assets to track
⬣ Physical: servers, networks, appliances
⬣ Software: OS, applications
⬣ Configuration: physical setup, connections,
software settings, policies, hardening
Decentralized responsibilities
Complex configuration management
Challenges
⬣ Different CIs complicates procedures
⬣ Cannot eproduce a “consistent” release
⬣ Responsibility crosses different teams
⬣ Hard to plan new and changed services
Control processes are central to all ITSM processes

Code as application stack
Code as service
Code as infrastructure
New generation DevOps

Application stack as code: Docker containers

Sample Dockerfile
FROM centos:7MAINTAINER Kwan Koon WaADD ./mysql-setup.sh /tmp/mysql-setup.shRUN /bin/sh /tmp/mysql-setup.shEXPOSE 3306CMD ["/usr/sbin/mysqld"]
Docker⬣ Containers as file system layers⬣ Simplifies the installation and configuration of the software⬣ Code-based
Cloud-based infrastructure is all encompassing⬣ Computing instances, networks⬣ DNS, load balancing, content distribution⬣ Databases, file storage, archiving⬣ …
Terraform⬣ State management of cloud-based infrastructure⬣ Simplifies the build, modification and launch of the
infrastructure⬣ Platform agnostic⬣ Run “terraform apply”
Cloud-based infrastructure as code: Terraform

Sample Terraform file
resource "aws_elb" "frontend" {name = "frontend-load-balancer"listener {
instance_port = 8000instance_protocol = "http"lb_port = 80lb_protocol = "http"
}instances = ["${aws_instance.app.*.id}"]
}
resource "aws_instance" "app" {count = 5ami = "ami-408c7f28"instance_type = "t1.micro"
}

Combining both gives us “Code as Service: deploy an entire environment with a single command
Code as ApplicationContainers = entire software stack
Code as InfrastructureCloud infrastructure = entire
infrastructure
Code as ServiceSimplifies ITSM to the maximum using DevOps
Greatly simplifies ITSM processes:⬣ Design and transition of new or changed services ⬣ Configuration management⬣ Change management⬣ Release and deployment management
