  • Use of Open Source Cloud Technologies to Deliver Modern Public Health Services
    Use of open source cloud technologies to deliver modern public health services Francesco Giannoccaro 29th January 2020 About PHE ► Public Health England (PHE) is an executive agency of the Department of Health in the UK. PHE provide government, local government, the NHS, industry and the public with evidence-based professional, scientific and delivery expertise and support. ► Public Health England was established in 2013 to bring together public health specialists from more than 70 organisations into a single public health service. PHE employee about 5,500 staff, mostly scientists, researchers and public health professionals. ► PHE mission is to protect and improve the nation’s health and wellbeing, and reduce health inequalities. We do this through world-leading science, knowledge and intelligence, advocacy, partnerships and the delivery of specialist public health services. 2 Use of open-source technologies to deliver modern public health services Francesco Giannoccaro - London 2020/01/29 HIGHLIGHT THE AMBITIOUS AND INSPIRING MISSION PUBLIC HEALTH ENGLAND HAS. HOW THIS MISSION ALIGN TO THE OPEN SOURCE VALUES, IN THAT PHE AIMS TO DELIVER INNOVATIVE PUBLIC HEALTH SERVICES TO EVERYONE INDEPENDENTLY HOW RICH THEY ARE, REDUCING HEALTH INEQUALITY. Wide range of public health services PHE deliver a wide range of public health services including • research and scientific publications based on mathematical models such as Spatial Metapopulation Model for transmissible disease (eg Flu/Smallpox), predictive models applied to the Anthrax, inference problem to be able to infer: likely size of outbreak, location of source, spatial extent, etc • pathogen genomics service, based on whole genome sequencing, for pathogen typing, surveillance and outbreak investigation.

  • Leveraging Containers and Openstack
    Leveraging Containers and OpenStack A Comprehensive Review Introduction Imagine that you are tasked to build an entire private cloud infrastructure from the ground up. You have a limited budget, a small but dedicated team, and are asked to pull off a miracle. A few years ago, you’d build an infrastructure with applications running in virtual machines, with some bare-metal machines for legacy applications. As infrastructure has evolved, virtual machines (VMs) enabled greater levels of efficiency and agility, but VMs alone don’t completely meet the needs of an agile approach to application deployment. They continue to serve as a foundation for running many applications, but increasingly, developers are looking toward the emerging trend of containers for leading-edge application development and deployment because containers offer increased levels of agility and efficiency. Container technologies like Docker and Kubernetes are becoming the leading standards for building containerized applications. They help free organizations from complexity that limits development agility. Containers, container infrastructure, and container deployment technologies have proven themselves to be very powerful abstractions that can be applied to a number of different use cases. Using something like Kubernetes, an organization can deliver a cloud that solely uses containers for application delivery. But a leading-edge private cloud isn’t just about containers, and containers aren’t appropriate for all workloads and use cases. Today, most private cloud infrastructures need to encompass bare-metal machines for managing infrastructure, virtual machines for legacy applications, and containers for newer applications. The ability to support, manage and orchestrate all three approaches is the key to operational efficiency.

  • Ansible 2.2 Documentation Release 2.4
    Ansible 2.2 Documentation Release 2.4 Ansible, Inc October 06, 2017 Contents 1 About Ansible 1 i ii CHAPTER 1 About Ansible Welcome to the Ansible documentation! Ansible is an IT automation tool. It can configure systems, deploy software, and orchestrate more advanced IT tasks such as continuous deployments or zero downtime rolling updates. Ansible’s main goals are simplicity and ease-of-use. It also has a strong focus on security and reliability, featuring a minimum of moving parts, usage of OpenSSH for transport (with other transports and pull modes as alternatives), and a language that is designed around auditability by humans–even those not familiar with the program. We believe simplicity is relevant to all sizes of environments, so we design for busy users of all types: developers, sysadmins, release engineers, IT managers, and everyone in between. Ansible is appropriate for managing all envi- ronments, from small setups with a handful of instances to enterprise environments with many thousands of instances. Ansible manages machines in an agent-less manner. There is never a question of how to upgrade remote daemons or the problem of not being able to manage systems because daemons are uninstalled. Because OpenSSH is one of the most peer-reviewed open source components, security exposure is greatly reduced. Ansible is decentralized–it relies on your existing OS credentials to control access to remote machines. If needed, Ansible can easily connect with Kerberos, LDAP, and other centralized authentication management systems. This documentation covers the current released version of Ansible (2.3) and also some development version features (2.4).
