Automation. 4 Eclipsys Solutions Feb-22

Automation. Different levels and areas – almost everything can be automated. Automated deployments. Orchestration. Application deployments. Security. Configuration management 5 Eclipsys Solutions Feb-22

Why in the cloud? Cloud is the best place to start and to apply automation techniques. Self-service interface and API. Tools to use the API to deploy IAC. Autoscaling. Infrastructure as a Service Infrastructure as Code Autoscaling 6 Eclipsys Solutions Feb-22

Tools There is no tool which can do everything. 7 Eclipsys Solutions Feb-22

Tools. Packer. Terraform. Resource manager. Docker. Kubernetes. 8 Eclipsys Solutions Feb-22

9 Eclipsys Solutions Feb-22 Packer.

Packer. Create custom image. Oracle Cloud Infrastructure region Source image VM Apply configuration. Create custom image Destroy VM 10 Eclipsys Solutions Feb-22

Packer. Custom images – region scope. Move to another region using OCI object storage. Identification using OCID (names are not unique). Git or another versioning tool for development. 11 Eclipsys Solutions Feb-22

12 Eclipsys Solutions Feb-22 Demo. What could possibly go wrong?

13 Eclipsys Solutions Feb-22 Terraform.

What is Terraform? Infrastructure as Code (Ia. C). To build, change and to destroy using versioning tools. Run it to manage OCI, AWS, Azure and many others. Terraform registry – community repository. https: //registry. terraform. io/ Terraform cloud – collaboration tool. https: //app. terraform. io 14 Eclipsys Solutions Feb-22

Terraform in action. git checkout … Write terraform scripts. terraform plan Plan Apply State file. OCI region. OCI compartment. Create resources in OCI Destroy terraform apply 15 Eclipsys Solutions Feb-22

Terraform state file - source of truth. With new version can discover resources in compartment. Possible to create SVG file using terraform state file. Terraform enterprise or terraform cloud for collaboration. OCI Resource Manager – native OCI Terraform service. 16 Eclipsys Solutions Feb-22

17 Eclipsys Solutions Feb-22 Demo. What could possibly go wrong?

Resource Manager OCI. git checkout … Write terraform scripts. Zip the scripts to a file Create a new RM stack and upload the zip file OCI region. OCI compartment. zip stack 01. zip * RM stack jobs. Plan Apply Destroy Edit variables. 18 Eclipsys Solutions Feb-22
