Openstack Designate
OpenStack Designate Stephan Lagerholm Graham Hayes What is OpenStack? OpenStack is a free open standard cloud computing platform, mostly deployed as infrastructure-as-a-service (IaaS) in both public and private clouds where virtual servers and other resources are made available to users. The software platform consists of interrelated components that control diverse, multi-vendor hardware pools of processing, storage, and networking resources throughout a data center. Users either manage it through a web-based dashboard, through command-line tools, or through RESTful web services. OpenStack began in 2010 as a joint project of Rackspace Hosting and NASA. As of 2012, it was managed by the OpenStack Foundation (Source: Wikipedia) 2 Designate • Designate started as a project to maintain DNS infrastructure for OpenStack Users. It was an ecosystem project that was in production at both HP’s and Rackspace’s clouds. During 2015, Designate was moved into OpenStack Foundation and in 2017 it became a registered trademark. • Designate is providing API, CLI and a Graphical User interface so that OpenStack Users can setup and make changes to DNS data. The zones are thereafter exposed to secondary DNS servers via Zone Transfers. • Officially Bind 9.X and PowerDNS 4.X is supported although other DNS servers are known to work too. Most resource Record Types such as A, AAAA, PTR, CNAME, NS, MX, etc are supported 3 Producer Producer Backend Producer Producer Producer Worker Customer Facing API Central DNS Servers Standard XFR Secured by TSIG Nova / DB Mini -

Enabling Intel® Virtualization Technology Features and Benefits
WHITE PAPER Intel® Virtualization Technology Enterprise Server Enabling Intel® Virtualization Technology Features and Benefits Maximizing the benefits of virtualization with Intel’s new CPUs and chipsets EXECUTIVE SUMMARY Although virtualization has been accepted in most data centers, some users have not yet taken advantage of all the virtualization features available to them.

Paravirtualization (PV)
Full and Para Virtualization Dr. Sanjay P. Ahuja, Ph.D. Fidelity National Financial Distinguished Professor of CIS School of Computing, UNF x86 Hardware Virtualization The x86 architecture offers four levels of privilege known as Ring 0, 1, 2 and 3 to operating systems and applications to manage access to the computer hardware. While user level applications typically run in Ring 3, the operating system needs to have direct access to the memory and hardware and must execute its privileged instructions in Ring 0. x86 privilege level architecture without virtualization Technique 1: Full Virtualization using Binary Translation This approach relies on binary translation to trap (into the VMM) and to virtualize certain sensitive and non-virtualizable instructions with new sequences of instructions that have the intended effect on the virtual hardware. Meanwhile, user level code is directly executed on the processor for high performance virtualization. Binary translation approach to x86 virtualization Full Virtualization using Binary Translation This combination of binary translation and direct execution provides Full Virtualization as the guest OS is completely decoupled from the underlying hardware by the virtualization layer. The guest OS is not aware it is being virtualized and requires no modification. The hypervisor translates all operating system instructions at run-time on the fly and caches the results for future use, while user level instructions run unmodified at native speed. VMware’s virtualization products such as VMWare ESXi and Microsoft Virtual Server are examples of full virtualization. Full Virtualization using Binary Translation The performance of full virtualization may not be ideal because it involves binary translation at run-time which is time consuming and can incur a large performance overhead.
