This crash course is designed to give an overview of cloud computing architecture and the open source software that can be used to deploy and manage a cloud computing environment. Topics to be discussed in this session will include virtualization (KVM, LXC, and Xen Project), orchestration (Apache CloudStack, Eucalyptus, Open Nebula, and OpenStack), and storage (GlusterFS, Ceph, and others). The talk will also provide insight into how to deliver Platform-as-a-Service (PaaS) and what technologies can be used to compliment this evolving cloud computing paradigm. Systems administrators and IT generalists will leave the discussion with a general overview of the options at their disposal to effectively build and manage their own cloud computing environments using free and open source software and understand the capabilities and benefits of a host of technologies.

- Dashboard of Performance Openhub has a good graphical representation of code velocity and listing of developers – www.openhub.com Bitgeria Bitgeria does number of dashboards.
- 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.
- Type 1 Hypervisor – VMware, Xen Project, XenServer, Hyper-V Type 1 (or native, bare metal) hypervisors run directly on the host's hardware to control the hardware and to manage guest operating systems. A guest operating-system thus runs on another level above the hypervisor. Type 2 Hypervisor – VM Type 2 (or hosted) hypervisors run within a conventional operating-system environment. With the hypervisor layer as a distinct second software level, guest operating-systems run at the third level above the hardware. VMware Workstation and VirtualBox exemplify Type 2 hypervisors.

- Ansible Ansible's SSH-key based access allows contributors to the Fedora Project to assist in automating infrastructure while having access limited appropriately. Ansible is also used to roll out and manage clusters of machines and ISV software, such as Basho's flagship key-value store Riak. Capistrano Capistrano 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. RunDeck RunDeck 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. Func Func 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. Mcollective The 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. Delivering a very scalable and very fast parallel execution environment. Scalr Scalr is a pretty darn good open source cloud management tool. It provides both an automation framework (do Foo when Bar) and a web interface (where is this volume mounted) for managing infrastructure on the cloud, like EC2.

It supports multiple forms of authentication including standard username and password credentials, token-based systems and AWS-style logins. Image Service 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 quickly and more consistently if you are provisioning multiple servers than installing a server operating system and individually configuring additional services. It can also be used to store and catalog an unlimited number of backups. Telemetry Service The OpenStack Telemetry service aggregates usage and performance data across the services deployed in an OpenStack cloud. This powerful capability provides visibility and insight into the usage of the cloud across dozens of data points and allows cloud operators to view metrics globally or by individual deployed resources. Orchestration Service OpenStack Orchestration is a template-driven engine that allows application developers to describe and automate the deployment of infrastructure. The flexible template language can specify compute, storage and networking configurations as well as detailed post-deployment activity to automate the full provisioning of infrastructure as well as services and applications. Through integration with the Telemetry service, the Orchestration engine can also perform auto-scaling of certain infrastructure elements.

- Debate: How Many Open Source Platforms Are Enough? http://www.enterprisetech.com/2014/06/23/debate-many-open-source-platforms-enough/ OpenStack came in for the most criticism for issues such cost of deployment and maintenance. “OpenStack is not a product,” Kemp responded. “If you are building a large infrastructure, it’s more like a tool kit. It gives you a lot of technologies that do take a lot of effort to integrate.” The tool kit is used to create a product, Kemp stressed.

- 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.

- Open Flow OpenFlow 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
- Floodlight - http://www.projectfloodlight.org/floodlight/ - OpenFlow – works with physical- and virtual- switches that speak the OpenFlow protocol - Apache-licensed – lets you use Floodlight for almost any purpose Open community Floodlight is developed by an open community of developers. We welcome code contributions from active participants and we’ll openly share information on project status, roadmap, bugs, etc. Easy to Use- Floodlight is drop dead simple to build and run. Read through the Documentation (link) Tested and Supported – Floodlight is the core of a commercial controller product from Big Switch Networks (link) and is actively tested and improved by a community of professional developers. Indigo - http://www.projectfloodlight.org/indigo/ Indigo is an open source project aimed at enabling support for OpenFlow on physical and hypervisor switches. Big Switch has helped numerous companies OpenFlow enable their equipment, and we provide firmware for a number of popular switches. Indigo is the basis of Switch Light by Big Switch Networks. - See more at: http://www.projectfloodlight.org/indigo/#sthash.K7LiHcqc.dpuf Lincx - https://github.com/FlowForwarding/lincx LINCX is a pure OpenFlow software switch written in Erlang. It runs within a separate domain under Xen hypervisor using LING (erlangonxen.org). LINCX is a new faster version of LINC-Switch. Open Daylight – http://www.opendaylight.com The 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. Open vSwitch Open 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
- Why Open vSwitch - http://git.openvswitch.org/cgi-bin/gitweb.cgi?p=openvswitch;a=blob_plain;f=WHY-OVS;hb=HEAD Hypervisors need the ability to bridge traffic between VMs and with theoutside world. On Linux-based hypervisors, this used to mean using thebuilt-in L2 switch (the Linux bridge), which is fast and reliable. So, it is reasonable to ask why Open vSwitch is used. The answer is that Open vSwitch is targeted at multi-server virtualization deployments, a landscape for which the previous stack is not well suited. These environments are often characterized by highly dynamic end-points, the maintenance of logical abstractions, and (sometimes) integration with or offloading to special purpose switching hardware.
- NetFlix AWS Toolbag – http://netflix.github.com Over 25 projects developed by NetFlix to manager their cloud deployments. Asgard Asgard is a web-based tool for managing cloud-based applications and infrastructure. Astyanaz Astyanax is a high level Java client for Apache Cassandra.

Chaos Monkey, the first member, is a resiliency tool that helps ensure that your applications can tolerate random instance failures
- Private cloud The 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 cloud The cloud infrastructure is made available to the general public or a large industry group and is owned by an organization selling cloud services. Hybrid cloud The 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).

The data can then be visualized through graphite's web interfaces.
- These tools are all appropriate for Linux guest operating systems, Windows operating system provisioning is not well addressed in OSS. Axembler Provisonr Provisionr 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. Cobbler Cobbler 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. Crowbar Bare metal provisioning for CloudStack developed by Dell using Opscode Chef. Juju Metal 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 Spacewalk Spacewalk 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.
- Big data the term for a collection of data sets so large and complex that it becomes difficult to process using on-hand database management tools or traditional data processing applications. The challenges include capture, curation, storage, search, sharing, transfer, analysis[4] and visualization. The trend to larger data sets is due to the additional information derivable from analysis of a single large set of related data, as compared to separate smaller sets with the same total amount of data, allowing correlations to be found to "spot business trends, determine quality of research, prevent diseases, link legal citations, combat crime, and determine real-time roadway traffic conditions.
- NoSQL In 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 Cassandra The 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. Hypertable Hypertable 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 MongoDB (from "humongous") is a cross-platform document-oriented database system. Redis Redis 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 Riak is known for its ability to distribute data across nodes using consistent hashing in a simple key/value scheme in namespaces called buckets.
- MapReduce is a programming model for processing large data sets with a parallel, distributed algorithm on a cluster. A MapReduce program is composed of a Map() procedure that performs filtering and sorting (such as sorting students by first name into queues, one queue for each name) and a Reduce() procedure that performs a summary operation (such as counting the number of students in each queue, yielding name frequencies). The "MapReduce System" (also called "infrastructure" or "framework") orchestrates by marshalling the distributed servers, running the various tasks in parallel, managing all communications and data transfers between the various parts of the system, and providing for redundancy and fault tolerance.
