Types of cloud​

  • Public: AWS, GCP, Azure, DigitalOcean... Shares compute resources among different customers.
  • Private (on-premises): OpenStack, VMware...
  • Hybrid: private & public clouds connected together. See https://aws.amazon.com/hybrid

Tools​

Server Images​

Snapshot of the OS, software, files...

Two categories: Virtual Machines and Containers.

  • Docker
  • Packer
  • Vagrant. For local development environments.

Configuration Management​

Install software on existing servers.

  • Ansible
  • Chef
  • Puppet

More tools: https://en.wikipedia.org/wiki/Comparison_of_open-source_configuration_management_software

Note that Ansible can do some provisioning too (automates provisioning, configuration management, application deployment, orchestration, and many other IT processes - source), but it's better to use a provisioning tool.

info

If you use server images (Docker, Packer), you don't have much need for configuration management tools, you only need provisioning tools. For example, use Terraform and Docker together.

If you don't use server images, it's common to use provisioning and configuration tools together. For example, use Terraform to provision the servers and Ansible to configure them.

Provisioning​

To create the actual infrastructure (servers, databases, queues, load balancers, firewalls, SSL certificates etc.).

  • Terraform
  • CloudFormation
  • Pulumi
  • Azure Resource Manager
info

Provisioning tools can also do some configuration. For example, you can run user data scripts on an EC2 machine using CloudFormation and Terraform.

Orchestration​

  • Kubernetes
  • ECS
  • Docker Swarm
  • Nomad
  • Heat (OpenStack)
