BotchagalupeMarks for September 12th – 14:54

These are my links for September 12th from 14:54 to 14:55:
- Micro vs. Macro Information Retrieval | The Noisy Channel – The Probably Irrelevant blog has been quiet for a while, but I was happy to see a new post there by Miles Efron about “micro-IR“. He characterizes micro-IR, as distinct from macro or general IR, as follows:
- Virtualization 3.0: Cloud-wide VM migration and memory de-duplication – For those unfamiliar with my background, I authored a full x86 PC emulation project in the 1990's, called bochs. It was used in one form or another, by a number of virtualization players, including an R&D project at Stanford which became VMware. It's been interesting watching x86 virtualization mature, from the early days of it being used as a developer's tool and then on to server consolidation (what I call virtualization 1.0). Consolidation is an interesting proposition of its own, making use of the VM level of abstraction to pack more work onto less physical resources. But it's still a very static technology in that VMs need to be booted and shut-down to be moved to different hardware.
- Virtual Infrastructure Management Private and Hybrid Clouds – More often than not, a “cloud” refers to an “Infrastructure-as-a-Service” (IaaS) cloud, such as Amazon EC2,
where IT infrastructure is deployed in a cloud provider’s datacenter in the form of virtual machines. With the growing
popularity of IaaS clouds, an ecosystem of tools and technologies is emerging that can transform an organization’s
existing infrastructure into a private cloud or a hybrid cloud. In this article, we present OpenNebula, an open source
virtual infrastructure manager that can be used to deploy virtualized services on both a local pool of resources and
on external IaaS clouds, and Haizea, a resource lease manager that can act as a scheduling backend for OpenNebula
providing features not found in other cloud software or virtualization-based datacenter management software, such as
advance reservations and resource preemption, which we argue to be specially relevant for private and hybrid clouds.
