MANAGED / OSS SERVERLESS (FAAS)
• OCI Functions is a fully managed, multi-tenant, highly scalable, on-demand, FaaS platform
• Built on enterprise-grade Oracle Cloud Infrastructure and powered by the Fn Project (OSS)
engine
• Flexible dev environments: Cloud Shell, local, OCI Compute/OKE
• Fn Project: Open-source, container-native, serverless platform
• Programming Languages (polyglot): Java, Python, Node.js, Golang, Ruby, C#

8. Azure Functions

8
MANAGED SERVERLESS (FAAS)
• Azure Functions is a managed serverless (FaaS) by Microsoft
• Not supported by an Open-source framework like Fn Project
• Options for a local dev environment depend on the target language: VS Code, Azure
Functions Core Tools, Maven,
• Programming Languages (polyglot): C#, Java, Python, Node.js, Powershell

9. OCI DevOps

DEVOPS MANAGED SERVICE
• CI/CD (automation) for developers targeting OCI - instances, K8s, and functions
• Deployment pipelines are free to use for OCI customers
• Blue-Green deployments and Canary deployments
• Connection to external repos such as GitHub, GitLab, Bitbucket, GitLab
• DevOps using the Oracle Cloud Console, REST API, and CLI
• Terraform, Powershell, Ansible, Chef
• (OCI) DevOps plugin for Jenkins, Grafana, etc.
• A DevOps Engineer's Guide to OCI

10. GitHub Actions

DEVOPS MANAGED SERVICE (CI/CD)
• GitHub Actions - CI/CD to automate your build, test, and deployment pipelines
• Run workflows when events happen in your repository
• GitHub provides Linux, Windows, and macOS VMs (runners) to run your workflows, or you
can use your your own self-hosted runners (on-prem or cloud)
• Components of GitHub Actions: workflow -> triggered when an event occurs in your repo
• Workflow -> one or more jobs (with runners) -> steps (script or action)

11. IaC - Terraform

INFRASTRUCTURE AS CODE
• HashiCorp created Terraform and the Hashicorp Configuration Language (HCL) as open-
source (MPL 2.0)
• Terraform is vastly adopted as a tool for IaC (focus on provisioning) along with Ansible
(configuration)
• Terraform providers support Oracle OCI, Azure, AWS, on-prem, hybrid and multi-cloud
• Recently, HashiCorp announced its decision to switch from Mozilla Public License v2. 0
(MPL 2.0) to Business Source License (BSL)
• The OpenTF Manifesto
