Editor's Notes
- #5 Infinite Probability Drive The Infinite Improbability Drive is a faster-than-light drive. The most prominent usage of the drive is in the starship Heart of Gold. It is based on a particular perception of quantum theory: a subatomic particle is most likely to be in a particular place, such as near the nucleus of an atom, but there is also an infintesimally small probability of it being found very far from its point of origin (for example close to a distant star). Thus, a body could travel from place to place without passing through the intervening space (or hyperspace, for that matter), if you had sufficient control of probability.Reference : Michael Lockwood (2005). The Labyrinth of Time: introducing the universe. Oxford University Press. ISBN 0-19-924995-4.
- #7 Cloud Software as a Service (SaaS) – The Application CloudThe capability provided to the consumer is to use the provider’s applications running on a cloud infrastructure. The applications are accessible from various client devices through a thin client interface such as a web browser (e.g., web-based email). The consumer does not manage or control the underlying cloud infrastructure including network, servers, operating systems, storage, or even individual application capabilities, with the possible exception of limited user-specific application configuration settings.Cloud Platform as a Service (PaaS) – The Development Cloud The capability provided to the consumer is to deploy onto the cloud infrastructure consumer-created or acquired applications created using programming languages and tools supported by the provider. The consumer does not manage or control the underlying cloud infrastructure including network, servers, operating systems, or storage, but has control over the deployed applications and possibly application hosting environment configurations.Cloud Infrastructure as a Service (IaaS). – Systems CloudThe capability provided to the consumer is to provision processing, storage, networks, and other fundamental computing resources where the consumer is able to deploy and run arbitrary software, which can include operating systems and applications. The consumer does not manage or control the underlying cloud infrastructure but has control over operating systems, storage, deployed applications, and possibly limited control of select networking components (e.g., host firewalls).
- #8 Private cloudThe cloud infrastructure is operated solely for an organization. It may be managed by the organization or a third party and may exist on premise or off premise.Public cloudThe cloud infrastructure is made available to the general public or a large industry group and is owned by an organization selling cloud services.Hybrid cloudThe cloud infrastructure is a composition of two or more clouds (private, community, or public) that remain unique entities but are bound together by standardized or proprietary technology that enables data and application portability (e.g., cloud bursting for load balancing between clouds).
- #9 The Kill-o-Zap is a weapon first appearing in the novel The Hitchhiker's Guide to the Galaxy, wielded by the police from Blagulon Kappa when they come to Magrathea to arrest Zaphod. It is referenced throughout the series in the role of a standard and widespread brand of raygun.In the novel The Restaurant at the End of the Universe it is described in more detail:The designer of the gun had clearly not been instructed to beat about the bush. 'Make it evil,' he'd been told. 'Make it totally clear that this gun has a right end and a wrong end. Make it totally clear to anyone standing at the wrong end that things are going badly for them. If that means sticking all sort of spikes and prongs and blackened bits all over it then so be it. This is not a gun for hanging over the fireplace or sticking in the umbrella stand, it is a gun for going out and making people miserable with.'In the novel Life, the Universe and Everything, the group arms themselves with Kill-o-Zap guns against the Krikkiters. Arthur "fumbled to release the safety catch and engage the extreme danger catch as Ford had shown him. He was shaking so much that if he'd fired at anybody at that moment he probably would have burnt his signature on them."In the 2005 movie adaptation, the gun has a sophisticated look. It is more of a white circle that covers the hand and has a trigger on the inside. This version is wielded by Marvin.

- #11 Top choices for Cloud Computing are Xen and KVM.OpenVZ, container virtualization for Linux, is an interesting option as it has a very minimal overhead to scale application space similar to containers like BSD Jails. Advantage is that memory allocation is soft and unutilized memory can be used by other applications.
- #12 OVFAn OVF package consists of several files, placed in one directory. A one-file alternative is the OVA package, which is a TAR file with the OVF directory inside.OVF is a packaging format for software appliances. From a technical point of view, an OVF is a transport mechanism for virtual machine templates. One OVF may contain a single VM, or many VMs (it is left to the software appliance developer to decide which arrangement best suits their application). OVFs must be installed before they can be run; a particular virtualization platform may run the VM from the OVF, but this is not required. If this is done, the OVF itself can no longer be viewed as a “golden image” version of the appliance, since run-time state for the virtual machine(s) will pervade the OVF. Moreover the digital signature that allows the platform to check the integrity of the OVF will be invalidAn Amazon Machine Image (AMI) is a special type of virtual appliance which is used to instantiate (create) a virtual machine within the Amazon Elastic Compute Cloud. It serves as the basic unit of deployment for services delivered using EC2..Amazon AMI An Amazon Machine Image (AMI) is a special type of virtual appliance which is used to instantiate (create) a virtual machine within the Amazon Elastic Compute Cloud. It serves as the basic unit of deployment for services delivered using EC2. Like all virtual appliances, the main component of an AMI is a read-only filesystem image which includes an operating system (e.g., Linux, UNIX, or Windows) and any additional software required to deliver a service or a portion of it.[2]The AMI filesystem is compressed, encrypted, signed, split into a series of 10MB chunks and uploaded into Amazon S3 for storage. An XML manifest file stores information about the AMI, including name, version, architecture, default kernel id, decryption key and digests for all of the filesystem chunks.An AMI does not include a kernel image, only a pointer to the default kernel id, which can be chosen from an approved list of safe kernels maintained by Amazon and its partners (e.g., RedHat, Canonical, Microsoft). Users may choose kernels other than the default when booting an AMI.QCOW2 – QEMU “Copy on Write” Version 2qcow stands for "QEMU Copy On Write" and denotes a disk storage optimization strategy that delays allocation of storage until it is actually needed. QEMU is an emulator and virtual machine container, and it can use a variety of virtual disk images which are generally associated with specific guests operating systems.qcow2 is a newer version of the qcow format. QEMU can use a base image which is read-only, and store all writes to the qcow2 image. Among the QEMU supported formats, this is the most versatile format. Features include smaller images (useful if the filesystem does not support holes, for example on FAT32), optional AES encryption, zlib based compression and support of multiple VM snapshots. qemu and xen have retained the qcow format for backwards compatibility. Users can easily convert qcow disk images to the qcow2 format.VMDK - Virtual Machine Disk VMDK (Virtual Machine Disk) is a file format used for virtual appliances developed for VMware products. The format is a container for virtual hard disk drives to be used in virtual machines like VMware Workstation or Virtualbox. VMDK is an open format.IMGThe IMG file extension is used by files which are standardized raw dumps of a disk, and by files in various formats created by different imaging programs.Xen can use raw disk images and physical disks as filesystems for a Xen based domainU. Another option is to use the disk images used by QEMU. VHD – Virtual Hard Disk Virtual Hard Disk format started by Connectix (now part of Microsoft) made open through the Microsoft Open Specification Promise.VHDs are implemented as files that reside on the native host file system. The following types of VHD formats are supported by Microsoft Virtual PC and Virtual Server:Fixed hard disk image: a file that is allocated to the size of the virtual disk. Fixed VHDs consist of a raw disk image followed by a VHD footer (512 or formerly 511 bytes).[1]Dynamic hard disk image: a file that at any given time is as large as the actual data written to it, plus the size of the header and footer. Dynamic and differencing VHDs begin with a copy of the VHD footer (padded to 512 bytes), and for dynamic or differencing VHDs created by Microsoft products this results in a VHD-cookie string conectix at the begin of the VHD file.[1]Differencing hard disk image: a set of modified blocks (maintained in a separate file referred to as the "child image") in comparison to a parent image. The Differencing hard disk image format allows the concept of Undo Changes: when enabled, all changes to a hard drive contained within a VHD (the parent image) are stored in a separate file (the child image). Options are available to undo the changes to the VHD, or to merge them permanently into the VHD. Different child images based on the same parent image also allow "cloning" of VHDs; at least the globally unique identifier (GUID) must be different.Linked to a hard disk: a file which contains a link to a physical hard drive or partition of a physical hard drive

- #16 Nova – Compute Fabric Controller similar to Amazon EC2 Nova is the project name for OpenStack Compute, a cloud computing fabric controller, the main part of an IaaS system. Individuals and organizations can use Nova to host and manage their own cloud computing.Component based architecture: Quickly add new behaviorsHighly available: Scale to very serious workloadsFault-Tolerant: Isolated processes avoid cascading failuresRecoverable: Failures should be easy to diagnose, debug, and rectifyOpen Standards: Be a reference implementation for a community-driven apiAPI Compatibility: Nova strives to provide API-compatible with popular systems like Amazon EC2Object Storage - Swift – Object Storage like Amazon S3Object Storage is ideal for cost effective, scale-out storage. It provides a fully distributed, API-accessible storage platform that can be integrated directly into applications or used for backup, archiving and data retention. Block Storage allows block devices to be exposed and connected to compute instances for expanded storage, better performance and integration with enterprise storage platforms, such as NetApp, Nexenta and SolidFire.Image Service “Glance”The OpenStack Image Service provides discovery, registration and delivery services for disk and server images. The ability to copy or snapshot a server image and immediately store it away is a powerful capability of the OpenStack cloud operating system. Stored images can be used as a template to get new servers up and running quicklyand more consistently if you are provisioning multiple serversthan installing a server operating system and individually configuring additional services. It can also be used to store and catalog an unlimited number of backups.Identity Service – “Keystone”OpenStack Identity provides a central directory of users mapped to the OpenStack services they can access. It acts as a common authentication system across the cloud operating system and can integrate with existing backend directory services like LDAP. It supports multiple forms of authentication including standard username and password credentials, token-based systems and AWS-style logins.Additionally, the catalog provides a queryable list of all of the services deployed in an OpenStack cloud in a single registry. Users and third-party tools can programmatically determine which resources they can access.As an administrator, OpenStack Identity enables you to:Configure centralized policies across users and systemsCreate users and tenants and define permissions for compute, storage and networking resources using role-based access control (RBAC) featuresIntegrate with an existing directory like LDAP, allowing for a single source of identity authentication across the enterpriseQuantum The Quantum API allows for creation and management of “virtual networks” each of which can have one or more “ports”. A port on a virtual network can be attached to a “network interface”, where a “network interface” is anything which can source traffic, such as a vNIC exposed by a virtual machine, an interface on a load balancer, and so on. These abstractions offered by Quantum (virtual networks, virtual ports,and network interfaces) are the building blocks for building and managing logical network topologies. Of course, the technology that implements Quantum is fully decoupled from the API (that is, the backend is “pluggable”).

WSO2 Stratos monitors CPU, memory and bandwidth utilization, and SLAs. Then it automatically scales up or down depending on the load. When new resources are needed, WSO2 Stratos transparently adds services and when load goes down, WSO2 Stratos automatically brings services down. Dynamic discovery enables services to automatically detect when resource allocations change; there is no need for manual monitoring or reconfiguration.
- #20 In the SDN architecture, the control and data planes are decoupled, network intelligence and state are logically centralized, and the underlying network infrastructure is abstracted from the applications. As a result, enterprises and carriers gain unprecedented programmability, automation, and network control, enabling them to build highly scalable, flexible networks that readily adapt to changing business needs
- #21 Software Defined Networking (SDN) is an emerging network architecture where network control is decoupled from forwarding and is directly programmable. This migration of control, formerly tightly bound in individual network devices, into accessible computing devices enables the underlying infrastructure to be abstracted for applications and network services, which can treat the network as a logical or virtual entity. This figure depicts a logical view of the SDN architecture. Network intelligence is (logically) centralized in software-based SDN controllers, which maintain a global view of the network. As a result, the network appears to the applications and policy engines as a single, logical switch. With SDN, enterprises and carriers gain vendor-independent control over the entire network from a single logical point, which greatly simplifies the network design and operation. SDN also greatly simplifies the network devices themselves, since they no longer need to understand and process thousands of protocol standards but merely accept instructions from the SDN controllers.
- #22 The limitations of the hardware-dependent network are preventing the enterprise from realizing the full potential of their cloud—and vastly limiting the return on their investment.To get the most from your cloud, you must untether your network.
- #23 Open FlowOpenFlow is an open standard that enables researchers to run experimental protocols in the campus networks we use every day. OpenFlow is added as a feature to commercial Ethernet switches, routers and wireless access points – and provides a standardized hook to allow researchers to run experiments, without requiring vendors to expose the internal workings of their network devices. OpenFlow is currently being implemented by major vendors, with OpenFlow-enabled switches now commercially available.In a classical router or switch, the fast packet forwarding (data path) and the high level routing decisions (control path) occur on the same device. An OpenFlow Switch separates these two functions. The data path portion still resides on the switch, while high-level routing decisions are moved to a separate controller, typically a standard server. The OpenFlow Switch and Controller communicate via the OpenFlow protocol, which defines messages, such as packet-received, send-packet-out, modify-forwarding-table, and get-stats.The data path of an OpenFlow Switch presents a clean flow table abstraction; each flow table entry contains a set of packet fields to match, and an action (such as send-out-port, modify-field, or drop). When an OpenFlow Switch receives a packet it has never seen before, for which it has no matching flow entries, it sends this packet to the controller. The controller then makes a decision on how to handle this packet. It can drop the packet, or it can add a flow entry directing the switch on how to forward similar packets in the future.OpenFlow is the first standard communications interface defined betweenthe control and forwarding layers of an SDN architecture. OpenFlow allows direct access to and manipulation of the forwarding plane of network devices such as switches and routers, both physical and virtual (hypervisor-based). It is the absence of an open interface to the forwarding plane that has led to the characterization of today’s networking devices as monolithic, closed, and mainframe-like. No other standard protocol does what OpenFlow does, and a protocol like OpenFlow is needed to move network control out of the networking switches to logically centralized control software
- #24 Floodlight - http://floodlight.openflowhub.org/The Floodlight controller is an enterprise-class, Apache-licensed, Java-based OpenFlow Controller. It is supported by a community of developers including a number of engineers from Big Switch Networks.OpenFlow is a open standard managed by the Open Networking Foundation (ONF). It specifies a protocol through switch a remote controller can modify the behavior of networking devices through a well-defined “forwarding instruction set”. Floodlight is designed to work with the growing number of switches, routers, virtual witches, and access points that support the OpenFlow standard.Open Daylight – http://www.opendaylight.comThe adoption of new technologies and pursuit of programmable networks has the potential to significantly improve levels of functionality, flexibility and adaptability of mainstream datacenter architectures. To leverage this abstraction to its fullest requires the network to adapt and evolve to a Software-Defined architecture. One of the architectural elements required to achieve this goal is a Software-Defined-Networking (SDN) platform that enables network control and programmability.OpenStack Networking “Quantum” – https://www.openstack.org/software/openstack-networking/OpenStack Networking is a pluggable, scalable and API-driven system for managing networks and IP addresses. Like other aspects of the cloud operating system, it can be used by administrators and users to increase the value of existing datacenter assets. OpenStack Networking ensures the network will not be the bottleneck or limiting factor in a cloud deployment and gives users real self service, even over their network configurations.Networking CapabilitiesOpenStack provides flexible networking models to suit the needs of different applications or user groups. Standard models include flat networks or VLANs for separation of servers and traffic.OpenStack Networking manages IP addresses, allowing for dedicated static IPs or DHCP. Floating IPs allow traffic to be dynamically rerouted to any of your compute resources, which allows you to redirect traffic during maintenance or in the case of failure. Users can create their own networks, control traffic and connect servers and devices to one or more networks.The pluggable backend architecture lets users take advantage of commodity gear or advanced networking services from supported vendors.Administrators can take advantage of software-defined networking (SDN) technology like OpenFlow to allow for high levels of multi-tenancy and massive scale.OpenStack Networking has an extension framework allowing additional network services, such as intrusion detection systems (IDS), load balancing, firewalls and virtual private networks (VPN) to be deployed and managed.Open vSwitchOpen vSwitch is a production quality, multilayer virtual switch licensed under the open source Apache 2.0 license. It is designed to enable massive network automation through programmatic extension, while still supporting standard management interfaces and protocols (e.g. NetFlow, sFlow, SPAN, RSPAN, CLI, LACP, 802.1ag). In addition, it is designed to support distribution across multiple physical servers similar to VMware's vNetwork distributed vswitch or Cisco's Nexus 1000V. See the full feature list here
- #25 Deep Thought is a computer that was created by the pan-dimensional, hyper-intelligent species of beings (whose three dimensional protrusions into our universe are ordinary white mice) to come up with the Answer to The Ultimate Question of Life, the Universe, and Everything. Deep Thought is the size of a small city. When, after seven and a half million years of calculation, the answer finally turns out to be 42, Deep Thought admonishes Loonquawl and Phouchg (the receivers of the Ultimate Answer) that "[he] checked it very thoroughly, and that quite definitely is the answer. I think the problem, to be quite honest with you is that you've never actually known what the question was.”Deep Thought does not know the ultimate question to Life, the Universe and Everything, but offers to design an even more powerful computer, Earth, to calculate it. After ten million years of calculation, the Earth is destroyed by Vogons five minutes before the computation is complete.

- #30 NoSQLIn computing, NoSQL (commonly interpreted as "not only SQL"[1]) is a broad class of database management systems identified by non-adherence to the widely used relational database management system model. NoSQL databases are not built primarily on tables, and generally do not use SQL for data manipulation.NoSQL database systems are often highly optimized for retrieval and appending operations and often offer little functionality beyond record storage (e.g. key–value stores). The reduced run-time flexibility compared to full SQL systems is compensated by marked gains in scalability and performance for certain data models.Apache CassandraThe Apache Cassandra database is the right choice when you need scalability and high availability without compromising performance. Linear scalability and proven fault-tolerance on commodity hardware or cloud infrastructure make it the perfect platform for mission-critical data. Cassandra's support for replicating across multiple datacenters is best-in-class, providing lower latency for your users and the peace of mind of knowing that you can survive regional outages.Cassandra's ColumnFamily data model offers the convenience of column indexes with the performance of log-structured updates, strong support for materialized views, and powerful built-in caching. Cassandra is in use at Netflix, Twitter, Urban Airship, Constant Contact, Reddit, Cisco, OpenX, Digg, CloudKick, Ooyala, and more companies that have large, active data sets. The largest known Cassandra cluster has over 300 TB of data in over 400 machines. HypertableHypertable is based on a design developed by Googl(e.g.BigTable clone) to meet their scalability requirements and solves the scale problem better than any of the other NoSQL solutions out there.Mongo DB RedisRedis is an open source, BSD licensed, advanced key-value store. It is often referred to as a data structure server since keys can contain strings, hashes, lists, sets and sorted sets.Riak

- #38 Ideally for the cloud you create management toolchains that automate the management of your cloud. So that the output of one tool informs the input of another.
- #39 These tools are all appropriate for Linux guest operating systems, Windows operating system provisioning is not well addressed in OSS. AxemblerProvisonrProvisionr solves the problem of cloud portability by hiding completely the APIs and only focusing on building a cluster that matches the same set of assumptions on all clouds, assumptions like: a specific OS, pre-installed packages and binaries, sane dns settings, ssh & vpn access etc. - think a solid foundation for configuration.As a secondary goal Provisionr will also provide primitives for building automatic or semi-automatic workflows for configuring and monitoring services, workflows that assume that all the machines share a common set of characteristics as described above.CobblerCobbler is a Linux installation server that allows for rapid setup of network installation environments. It glues together and automates many associated Linux tasks so you do not have to hop between lots of various commands and applications when rolling out new systems, and, in some cases, changing existing ones. With a simple series of commands, network installs can be configured for PXE, reinstallations, media-based net-installs, and virtualized installs (supporting Xen, qemu, KVM, and some variants of VMware). Cobbler uses a helper program called 'koan' (which interacts with Cobbler) for reinstallation and virtualization support. CrowbarBare metal provisioning for CloudStack developed by Dell using Opscode Chef. JujuMetal as a Service (MAAS)MAAS offers a nice UI to provision your Ubuntu servers. Each physical server (“node”) will be commissioned automatically on first boot. During the commissioning process administrators are able to configure hardware settings manually before an automated smoke test and burn-in test are done. Once commissioned, a node can be deployed on demand by name, or allocated to a queue for dynamic allocation to services being deployed on this MAAS.Salt Cloud Salt Cloud is a tool for provisioning salted minions across various cloud providers. Currently supported providers are:- Amazon EC2- GoGrid- HP Cloud (using OpenStack)- Joyent- Linode- OpenStack- Rackspace (using OpenStack)The salt-cloud command can be used to query configured providers, create VMs on them, deploy salt-minion on those VMs and destroy them when no longer needed.Salt Cloud requires Salt to be installed, but does not require any Salt daemons to be running. However, if used in a salted environment, it is best to run Salt Cloud on the salt-master, so that it can properly lay down salt keys when it deploys machines, and then properly remove them later. If Salt Cloud is run in this manner, minions will automatically be approved by the master; no need to manually authenticate them later.Deprecated SpacewalkSpacewalk manages software content updates for Red Hat derived distributions such as Fedora, CentOS, and Scientific Linux, within your firewall. You can stage software content through different environments, managing the deployment of updates to systems and allowing you to view at which update level any given system is at across your deployment. A clean central web interface allows viewing of systems and their software update status, and initiating update actions.

Ansible is also used to roll out and manage clusters of machines and ISV software, such as Basho's flagship key-value store Riak.CapistranoCapistrano is a developer tool for deploying web applications. It is typically installed on a workstation, and used to deploy code from your source code management (SCM) to one, or more servers.Capistrano recently added classes capabilities that match cobbler. RunDeckRunDeck is cross-platform open source software that helps you automate ad-hoc and routine procedures in data center or cloud environments. RunDeck allows you to run tasks on any number of nodes from a web-based or command-line interface. RunDeck also includes other features that make it easy to scale up your scripting efforts including: access control, workflow building, scheduling, logging, and integration with external sources for node and option data.FuncFunc allows for running commands on remote systems in a secure way, like SSH, but offers several improvements. Func allows you to manage an arbitrary group of machines all at once. Func automatically distributes certificates to all "slave" machines. There's almost nothing to configure. Func comes with a command line for sending remote commands and gathering data. There are lots of modules already provided for common tasks. Anyone can write their own modules using the simple Python module API. Everything that can be done with the command line can be done with the Python client API. The hack potential is unlimited. You'll never have to use "expect" or other ugly hacks to automate your workflow. It's really simple under the covers. Func works over XMLRPC and SSL. Since func uses certmaster, any program can use func certificates, latch on to them, and take advantage of secure master-to-slave communication. There are no databases or crazy stuff to install and configure. Again, certificate distribution is automatic too. McollectiveThe Marionette Collective AKA mcollective is a framework to build server orchestration or parallel job execution systems.Mcollective is used as a means of programmatic execution of Systems Administration actions on clusters of servers. MCollective use modern tools like Publish Subscribe Middleware and modern philosophies like real time discovery of network resources using meta data and not hostnames.
