The series starts with part 0 (preparation), and continues with part 1 (mostly about rpm-ostree ), part 2 (container storage), part 3 (rebase, upgrade, and rollback), part 4 (package layering and experimental features), and part 5 (containerized and non-containerized applications). Dusty Mabe has a multi-part blog series on Atomic Host.

Russell Bryant has a couple great articles on OVN— how to test OVN’s “EZ Bake” release with DevStack as well as an article on implementing OpenStack security groups using OVN ACLs (which in turn leverage the integration between Open vSwitch and the Linux kernel’s conntrack module). This is something I’ll have to investigate a bit more.

True, both have made huge strides in the hardware world to allow for blade repurposing, I/O, address, and storage naming portability, etc. However, in the software domain, each still relies on multiple individual products to accomplish tasks such as SW provisioning, HA/availability, VM management, load balancing, etc.

You can use a pair of NAT instances (this has scale limitations and adds complexity), you can use the new Managed NAT Gateway , or you can leverage a Squid proxy (or even an AutoScaling Group of Squid proxies, if you’re ambitious enough).

In the old days, IT departments had developed the tools and processes that they needed in order to deal with building large groups of new servers or handling a planned data center maintenance activity. Kotsovinos points out that a VM is really a collection of interconnected physical subsystems : server, storage, and network.

A specific angle I want to address here is that of infrastructure automation ; that is, the dynamic manipulation of physical resources (virtualized or not) such as I/O, networking, load balancing, and storage connections - Sometimes referred to as "Infrastructure 2.0". a Fabric), and network switches, load balancers, etc.

In essence, a server’s logical IO is consolidated down to a single (physical) converged network which carries data, storage and KVM traffic.

Converged Infrastructure and Unified Computing are both terms referring to technology where the complete server profile, including I/O (NICs, HBAs, KVM), networking (VLANs, IP load balancing, etc.), and storage connectivity (LUN mapping, switch control) are all abstracted and defined/configured in software.

Think of it this way: Fabric Computing is the componentization and abstraction of infrastructure (such as CPU, Memory, Network and Storage). The next step is to define in software the converged network, its switching, and even network devices such as load balancers. Provisioning of the network, VLANs, IP load balancing, etc.

For IaaS technology, the trunk is built of essential cloud core services: compute, networking and storage. API compatibility provided via a higher-level proxy would allow for the breakout of maintenance to a specific group of engineers focused on that requirement (and remove that burden from the individual service teams).
