- The prior slide described the CIO dilemma being required to do more with less. This will not happen the old fashion way and a new more disruptive approach is needed. 1. more use of OSS 2. new service delivery models – cloud 3. new business models – pay as you go and subscription based Most clouds are build on OSS and 80% of the workloads run on Linux. Open Standards are essential to ensure portability which is in the DNA of OSS collaboration between researchers with access to ARPANET made open standards which led the born of 1969. In 1973, Unix was re-written in the programming language C by Dennis Ritchie

- This slide is derived from the Gartner roadmap “From Virtualization to Cloud Computing”, and indicates the various levels of infrastructure enablement that IT organizations are engaging in today. Organizations often field more than one virtual / cloud project may be doing IT transformation to IaaS while at the same time running Cloud program initiatives. Focus has been on deriving economies and flexibility at one level via server virtualization and consolidation. Highly distributed and sprawled virtual environments that tend to result form those initiatives require management optimization and automation to be efffectivley controlled. Infrastructure as a Service (IaaS) capabilities are then engaged to support agile, self-service access to IT systems and services, again raising the management ante for addressing tracking, capacity management, resource utilization/optimization, In Hybrid Cloud, portable workloads across mixed hypervisors and policies to govern controlled access and usage are required, as well as chargeback and showback mechanisms. With CLOUDForms, the goal is to future proof your management investment and eliminate multiple disparate tools and tool sprawl which introduces problems of integration, multiple interfaces, and rising costs & training needs with multiple vendor point products. Allows your organization to incrementally build into cloud architectures at its own pace.

- Today, Linux is the primary platform for a majority of cloud-based applications. As a case in point, an October 2012 Wired magazine article cited a report by Newvem which illustrated Linux's dominant position, particularly pertaining to Amazon Web Services: At Wired’s request, Newvem — a company that sells management services to Amazon cloud customers — took at look at about 41,000 cloud machines run by several hundred customers. Its conclusion: Linux is twice as popular as Windows on Amazon Web Services. It was running on 67 percent of machines, compared to Windows’ 33 percent. With Linux as the go-to OS for many cloud users, we are also seeing workloads migrate to Linux for public, private, and hybrid clouds because of efficiency and flexibility of deployment. Companies at the cutting edge of cloud computing and the Internet are choosing Linux and open source, and often choose Red Hat Enterprise Linux. http://www.wired.com/wiredenterprise/2012/10/epic-microsoft-windows-fight/ http://www.redhat.com/resourcelibrary/case-studies/ http://csrc.nist.gov/publications/nistpubs/800-145/SP800-145.pdf http://www.ibm.com/developerworks/podcast/dwi/feature040611-dnielsen.html
- To set the proper context for our discussion, let’s take a look at the three best known cloud service delivery models, IaaS or Infrastructure as a Service, PaaS or Platform as a Service, And SaaS or Software as a Service. With each of these some portion of the technology stack is managed and controlled by the Cloud offering (whether public or private), and the rest is responsibility of the customer of the Cloud offering. They must manage and maintain the portion of the stack that is not managed by the Cloud offering. The benefit is that the customer can also CONTROL the design of this portion of the stack. For Infrastructure-as-a-Service, or IaaS, the customer must manage and control everything from the Operating System up. They must install the OS, the middleware, and the application code. This ultimately becomes only a small reduction in effort compared to bare-metal server management. For Software-as-a-Service, or SaaS, the customer doesn’t need to manage anything, but they also don’t control anything, not even the design of the application. The complete application is delivered from the Cloud for the user to use. This can be great UNLESS there is some application functionality that the customer needs that is not available in the application. I.e., the business application offered via SaaS may not meet the actual business needs of the user. Platform-as-a-Service, or PaaS (commonly pronounced “Paz”) offers a happy medium and allows the customer to control the design of the application but not worry about the underlying components of the stack. The management and maintenance of the complete application platform stack is abstracted away. The customer, typically a Developer in this case, can focus on their application design, code, and ultimately their application users. <next slide>
- PaaS allows us to make this leap from a Craftwork methodology to an Assembly Line methodology. PaaS both streamlines and standardizes the Application Development process. Instead of the unique, one-off processes that each application project used to go through, Utilization of a PaaS allows the deployment of a standardized methodology with a few distinct repeatable steps. Once the idea and budget are secured, then the App Dev team just simply starts working with the PaaS to code, test, and launch their application. PaaS provides the platform environment that allows Developers to start coding immediately. Server deployment, configuration and administration is all largely automated. This reduces the burden on Operations and reduces the delays that impact Development. And many industry analysts agree that the utilization of PaaS is going to be the key to allowing IT to be the demands of the business. <next slide>
- KVM - Kernel-based Virtual Machine. The virtual disk formats that it supports is inherited from QEMU since it uses a modified QEMU program to launch the virtual machine. The supported formats include raw images, the qcow2, and VMware formats. LXC - Linux Containers (through libvirt), use to run Linux-based virtual machines. QEMU - Quick EMUlator, generally only used for development purposes. UML - User Mode Linux, generally only used for development purposes. VMWare vSphere 4.1 update 1 and newer, runs VMWare-based Linux and Windows images through a connection with a vCenter server or directly with an ESXi host. Xen - XenServer, Xen Cloud Platform (XCP), use to run Linux or Windows virtual machines. You must install the nova-compute service in a para-virtualized VM. Hyper-V - Server virtualization with Microsoft's Hyper-V, use to run Windows, Linux, and FreeBSD virtual machines. Runs nova-compute natively on the Windows virtualization platform. Bare Metal - Not a hypervisor in the traditional sense, this driver provisions physical hardware through pluggable sub-drivers (for example, PXE for image deployment, and IPMI for power management). Docker is an open-source engine which automates the deployment of >applications as highly portable, self-sufficient containers which are >independent of hardware, language, framework, packaging system and hosting >provider.

- In many ways, the RHOS and RHEL value propositions are identical with Red Hat OpenStack (RHOS) being to OpenStack what Red Hat Enterprise Linux (RHEL) is to Linux. Red Hat has the proven capability of preparing and delivering an open source distribution for enterprise use and providing a stable, secure, and common platform that customers, ISV partners, IHV partners, and service provider partners can use to test and certify their software and hardware solutions. Operational competency necessary for maintain a stable platform with backported bugfixes and features. World-class processes and procedures required for the rigorous testing and QA necessary for enterprise-class products Worldwide enterprise class support service with consulting and training services Certified partner program Guest certifications – include Microsoft Windows (SVVP) Hardware certifications – broadest list of certified server, storage and networking platforms Leadership and influence of the upstream OpenStack product development process with the ability and motivation to act as customer advocate with upstream community
