1:58:46 Public Cloud Implications

In his presentation Joep Piscaer focused on high-level implications of public cloud services, why organizations think that public cloud is THE answer to their IT challenges, and the ways that introduction of public cloud into your environment will impact your work and your organization. He concluded with a few recommendations on what you should be doing to adapt to the new reality.

46:46 Case Study: Migrating Infrastructure into AWS

In summer 2019 we migrated most of the infrastructure into AWS, using a combination of VPC, EC2 and S3 to run a content web server and a static main web site.

The section also describes our integration with CloudFlare, and use of CloudFlare access to provide 2-factor authentication for management access and SSH sessions.

29:31 Building Virtual Machine Images

Provisioning scale-out VM sets, or virtual machines without outside SSH access, is one of the more interesting public cloud deployment challenges.

This section describes potential solutions, the tools you could use to generate VM images, and a few hints on using Ansible for cloud VM provisioning.

29:15 Deploying Network Virtual Appliances

Deploying redundant network virtual appliances in a public cloud virtual network is one of the hardest challenges you'll have to tackle in your public cloud networking journey.

Most network services appliances rely on tricks like layer-2 forwarding, IP address sharing, or static routing toward floating next-hop address to implement seamless failover. None of those tricks work in a typical public cloud environment... but don't despair; this section will outline most of the challenges you'll be facing, and give you a few design alternatives.

1:56:41 Storage in the 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.
