Networking in Public Cloud Deployments

This section describes:

• Self-study materials and live sessions;
• Hands-on exercises;
• Detailed course contents
• How you should progress through the course;

The first module of the course focuses on concepts, the big picture, and requirement collection phase. We'll discuss these topics:

• The difference between cloud services and typical enterprise IT infrastructure;
• Identifying the reliability and recovery requirements
• Cloud-native application architectures
• AWS and Azure concepts (regions, availability zones...)

Migrating to cloud infrastructure won't increase the speed- or reliability of application deployment if you continue to use the traditional manual processes, or configure one-off environments with GUI.

This module will describe the principles of automated workload deployment and commonly-used tools, and introduce infrastructure-as-code concepts.

Modern public clouds offer hundreds of services... most of them offered on top of common infrastructure components like virtual machines.

This module describes the basics of compute virtualization and focuses on container- and serverless services.

Virtual networking in public clouds is different - there are no layer-2 segments, IP routing has unexpected quirks, and subnets behave almost like VRFs.

This module introduces the typical cloud networking services, and describes how they are implemented in AWS and Azure.

It's harder and harder to ignore IPv6, and major public cloud providers already implemented numerous IPv6 features, first in public-facing infrastructure, then in virtual networks.

This module will introduce IPv6 concepts, describe where you might want to use IPv6 in your deployments, and how you could provide dual-stack connectivity to your customers while deploying IPv4 or IPv6-only virtual networks.

Just because you moved your applications into a public cloud doesn't mean that you don't have to worry about security - it becomes even more critical to protect your applications with the plethora of tools made available by public cloud providers.

This module describes the security basics of public cloud deployments and focuses on network security mechanisms.

Public cloud environments have numerous built-in network services, from network load balancers to application load balancers, web proxies, application firewalls, and content delivery network (CDN).

This module starts with the load balancing basics and describes network services available in AWS and Azure environments.

Public clouds providers usually design their infrastructure to be highly resilient, but they don't offer any high-availability assurances apart from availability and durability SLA - they expect you to design your applications to survive failures, and deploy them across multiple availability zones or regions.

This module describes the principles of building cloud-ready application architectures and lessons learned in traditional high-availability environments that apply equally well to public cloud deployments.

IT vendors love to talk about hybrid clouds (more so if they happen to have a product that can connect your data center with a public cloud in an arcane way) while the public cloud providers try to keep things simple and offer the same mechanisms we used for ages: direct connectivity, IPsec VPN and BGP routing protocol.

This module describes:

• Public cloud mechanisms you can use to build hybrid clouds;
• Alternate solutions you can use to connect your sites to a public cloud;
• Challenges of deploying your workloads in more than one public cloud (multi-cloud)

In the final module, we'll talk about DevOps, how to use DevOps concepts in a secure way, and how to deploy your first workload in a public cloud environment.
