Improve Manageability, Flexibility, Scalability, and Control with Hyperconverged Infrastructure Hyperconverged infrastructure (HCI) combines storage, compute, and networking in one unified system, managed locally or from the cloud. With HCI, you can leverage the cloud’s simplicity, flexibility, and scalability without losing control or compromising your ability to scale. In Hyperconverged Infrastructure Data Centers, best-selling author Sam Halabi demystifies HCI technology, outlines its use cases, and compares solutions from a vendor-neutral perspective. He guides you through evaluation, planning, implementation, and management, helping you decide where HCI makes sense, and how to migrate legacy data centers without disrupting production systems. The author brings together all the HCI knowledge technical professionals and IT managers need, whether their background is in storage, compute, virtualization, switching/routing, automation, or public cloud platforms. He explores leading solutions including the Cisco HyperFlex platform, VMware vSAN, Nutanix Enterprise Cloud, Cisco Application-Centric Infrastructure (ACI), VMware’s NSX, the open source OpenStack and Open vSwitch (OVS) / Open Virtual Network (OVN), and Cisco CloudCenter for multicloud management. As you explore discussions of automation, policy management, and other key HCI capabilities, you’ll discover powerful new opportunities to improve control, security, agility, and performance. Understand and overcome key limits of traditional data center designs Discover improvements made possible by advances in compute, bus interconnect, virtualization, and software-defined storage Simplify rollouts, management, and integration with converged infrastructure (CI) based on the Cisco Unified Computing System (UCS) Explore HCI functionality, advanced capabilities, and benefits Evaluate key HCI applications, including DevOps, virtual desktops, ROBO, edge computing, Tier 1 enterprise applications, backup, and disaster recovery Simplify application deployment and policy setting by implementing a new model for provisioning, deployment, and management Plan, integrate, deploy, provision, manage, and optimize the Cisco HyperFlex hyperconverged infrastructure platform Assess alternatives such as VMware vSAN, Nutanix, open source OpenStack, and OVS/OVN, and compare architectural differences with HyperFlex Compare Cisco ACI (Application- Centric Infrastructure) and VMware NSX approaches to network automation, policies, and security This book is part of the Networking Technology Series from Cisco Press, which offers networking professionals valuable information for constructing efficient networks, understanding new technologies, and building successful careers.

This book examines how the COVID-19 pandemic has engendered a new and challenging environment in which borders drawn around people, places, and social structures have hardened and new ones have emerged.Over the course of the COVID-19 pandemic, borders closed or became unwelcoming at the international, national, sub-national, and local levels. Debate persists as to whether those countries and territories that tightly managed their borders, like New Zealand, Australia, or Hong Kong, got it ‘right’ compared to those that did not. Without doubt, a majority of those who suffered and died throughout the pandemic have been those from vulnerable populations. Yet on the other hand, efforts taken to manage the spread of the disease, such as through border management, have also disproportionately affected those who are most vulnerable. How then is the right balance to be struck, acknowledging, too, the economic and other imperatives that may dissuade governments from taking public health steps? This book considers how international organizations, countries, and institutions within those countries should conceive of, and manage, borders as the world continues to struggle with COVID-19 and prepares for the next pandemic. Engaging a range of international, and sub-national, examples, the book thematizes the main issues at stake in the control and management of borders in the interests of public health.This book will be of considerable interest to academics in the fields of health law, anthropology, economics, history, medicine, public health, and political science, as well as policymakers and public health planners at national and sub-national levels.
