Study Notes
Terraform and Multicloud Infrastructure Management
- Terraform is a multicloud infrastructure management tool by Hashicorp that allows for automatic deployment of all resources in a controlled and predictable manner.
- It involves a graphical specification of infrastructure, translation into a textual specification (TF config), API checking of the deployed infrastructure, and determining and executing a plan to go from the current state to the desired infrastructure.
- Terraform Enterprise facilitates collaboration in a team by allowing configuration at a central server.
Cloud Management Platforms
- Third-party cloud management platforms manage a whole infrastructure with multiple servers, accounts, reports, etc.
- Common ways to organize workloads are by environment or workload, which identifies a set of components that deliver business value together.
- Sandboxing allows for experimentation, and guardrails are governance rules that can be rolled out on accounts to enforce compliance.
AWS Management and Security
- AWS Organizations consolidate multiple accounts into organizational units (OUs) and manage them centrally.
- IAM Identity Center allows central management of access to AWS accounts with temporary credentials.
- AWS Control Tower combines AWS Organizations with other services to manage access, orchestration, and compliance of a multi-account setup according to best practices.
- Enabling MFA for users is recommended.
Secrets Management
- Secrets management is responsible for managing sensitive information such as database connection strings.
- Access to sensitive information should be restricted, and debugging should be done in a controlled environment.
VMware vSphere
- VMware vMotion enables the migration of virtual machines from one host memory to another without service interruption.
- This allows administrators to off-load virtual machines, perform maintenance, resolve out-of-space issues, and upgrade VMFS.
- Storage vMotion (SVMotion) moves storage information in addition to guests, enabling datacenter-level VM migration.
- VMware Insights features include Dynamic Resource Scheduler, which schedules resources based on loads or capacity requirements, and Consolidated Backup, which is used for the backup of ESX servers.
