Introduction to Cloud Computing

This section introduces the public cloud concepts and services, deployment models (from infrastructure- to services deployments), typical management layers you might encounter while working with a public could, and the shared responsibilities model.

The second half of the section briefly introduces a plathora of cloud-related buzzwords, from DevOps and CI/CD to Cloud-Native environments.

The "introduction to public cloud concepts" can sound abstract without a realistic case studies. This section contains two interesting examples: securing a VM-based deployment, and a serverless application.

Cloud networking is different from whatever you were taught in a networking class or a textbook. Dynamic routing protocols are rare, layer-2 segments are almost non-existent, and the subnets could be either extremely limited or spanning the globe.

This section describes typical challenges one might encounter when trying to design networking infrastructure in a public cloud.

In this section, Howard Marks introduced the three types of cloud storage (object store, block storage, and file systems) and explained how the three major cloud providers (AWS, Azure, GCP) implemented them.

In the second part of his presentation, Howard focused on on-premises gateways, data mover solutions, and on-ramps, concluding with a few cautionary tales.

Multi-cloud networking is another buzzword that means approximately as much as cloud, intent-based, or software-defined. This section tries to address some of the multicloud networking myths and challenges.

In the Networking in Public Cloud Deployments online course Ned Bellavance described cloud deployment automation using infrastructure-as-code tools. His presentation included:

• Infrastructure-as-code concepts and tools;
• Terraform basics;
• Using Terraform with Azure;
• Terraform and server configuration management;
• Automating Terraform

In this section (from the Building the Next-Generation Data Center course) Ed Horley helps you plan the next few months after your boss tells you to move your data center to AWS cloud.
