Internet is everywhere, everything is connected to the Internet ... this is clearly the default assumption of almost any cloud native products and we can see it in a large majority of their documentation. In the real world of business, it is often extremely different. The Internet is a resource that has to be earned and accessing it can sometimes become complicated. Firewall, Proxy, DMZ, ACL , limited bandwidth... are all constraints that will get in your way and prevent you from reaching your goal. During this session, we will go through the most typical infrastructure that can be found in companies, and we will see what it is possible to put in place in terms of tooling to simplify life to the maximum. Container Runtime, Registry, Policy Management can be configured and adapted to work best in these particular situations. Many precise examples will be given so that you can reproduce them on your own infrastructure.

The presentation discusses the memory hierarchy and the use of container registries in DevOps.

• The memory hierarchy is based on the principles of temporal and spatial locality.
• The memory hierarchy consists of registers, cache, and RAM.
• The presentation provides a demonstration of a simple program and its disassembled instructions.
• Container registries have benefits but should be used judiciously.
• There are some great applications for container registries.
• The presentation invites discussion on RISC-V and container registries.

You know the registry as your most boring friend. You push and pull images, and it just works, but have you ever taken the time to really get to know it? What is the registry really like behind that unassuming OCI specification? What does it do when it’s not just distributing your images? Maybe it gets a little crazy on the weekend - maybe it has hidden talents you don’t know about. What would happen if this thankless hero went rogue? In this talk we will demonstrate unconventional registry implementations, including those that serve self-modifying and dynamically generated images. Along the way we’ll also take a look at how clients can utilize registries in interesting and unexpected ways, e.g. as a content-addressable key-value store or a general-purpose directed acyclic graph database. Attendees will walk away with a better understanding of what guarantees OCI images and registries provide, as well as how they can exploit the registry’s flexibility to benefit their own use cases.
