This book attempts to explore all you need to know regarding Infrastructure-as-Code (IaC). It will assist you in making informed decisions, if you have plans to implement IaC. As part of the DevOps practices, IaC offers the ability to manage, configure, and create complex infrastructures by means of executable code. When adopting IaC, the infrastructure is managed by defining the preferred state of the infrastructure in source files, and using a tool to help facilitate that. The source files consist of templates, policy definitions, configuration, code, and other related assets. A better infrastructure delivery can help improve the important aspects of software delivery performance that drive business outcomes. These include time to restore service, change failure rate, lead time for changes, and deployment frequency. What You'll Learn: Understand how IaC works. Explore tools and services for updating running servers, building server templates, and provisioning servers. Learn about immutable infrastructure and the tools needed to implement it. Comprehend how to make an object reproducible. Discover the best practices for managing a dynamic infrastructure. And lots more...
When doing a DR drill, have you found the run book to be out of sync with the current configuration? How many man-hours can be recovered through effective configuration management? Do you need a new release, version or patch level of the software? Is the service usage appropriate to capacity? Defining, designing, creating, and implementing a process to solve a challenge or meet an objective is the most valuable role… In EVERY group, company, organization and department. Unless you are talking a one-time, single-use project, there should be a process. Whether that process is managed and implemented by humans, AI, or a combination of the two, it needs to be designed by someone with a complex enough perspective to ask the right questions. Someone capable of asking the right questions and step back and say, 'What are we really trying to accomplish here? And is there a different way to look at it?' This Self-Assessment empowers people to do just that - whether their title is entrepreneur, manager, consultant, (Vice-)President, CxO etc... - they are the people who rule the future.

Use ACI fabrics to drive unprecedented value from your data center environment With the Cisco Application Centric Infrastructure (ACI) software-defined networking platform, you can achieve dramatic improvements in data center performance, redundancy, security, visibility, efficiency, and agility. In Deploying ACI, three leading Cisco experts introduce this breakthrough platform, and walk network professionals through all facets of design, deployment, and operation. The authors demonstrate how ACI changes data center networking, security, and management; and offer multiple field-proven configurations. Deploying ACI is organized to follow the key decision points associated with implementing data center network fabrics. After a practical introduction to ACI concepts and design, the authors show how to bring your fabric online, integrate virtualization and external connections, and efficiently manage your ACI network. You’ll master new techniques for improving visibility, control, and availability; managing multitenancy; and seamlessly inserting service devices into application data flows. The authors conclude with expert advice for troubleshooting and automation, helping you deliver data center services with unprecedented efficiency. Understand the problems ACI solves,and how it solves them Design your ACI fabric, build it, and interface with devices to bring it to life Integrate virtualization technologieswith your ACI fabric Perform networking within an ACI fabric (and understand how ACI changes data center networking) Connect external networks and devices at Layer 2/Layer 3 levels Coherently manage unified ACI networks with tenants and application policies Migrate to granular policies based on applications and their functions Establish multitenancy, and evolve networking, security, and services to support it Integrate L4–7 services: device types, design scenarios, and implementation Use multisite designs to meet rigorous requirements for redundancy and business continuity Troubleshoot and monitor ACI fabrics Improve operational efficiency through automation and programmability
So-called Intent-Based Networking (IBN) is founded on well-known SDN (Software-Defined Networking) and represents one of the most important emerging network infrastructure opportunities. The IBN is the beginning of a new era in the history of networking, where the network itself translates business intentions into appropriate network configurations for all devices. This minimizes manual effort, provides an additional layer of network monitoring, and provides the ability to perform network analytics and take full advantage of machine learning. The centralized, software-defined solution provides process automation and proactive problem solving as well as centralized management of the network infrastructure. With software-based network management, many operations can be performed automatically using intelligent control algorithms (artificial intelligence and machine learning). As a result, network operation costs, application response times and energy consumption are reduced, network reliability and performance are improved, network security and flexibility are enhanced. This will be a benefit for existing networks as well as evolved LTE-based mobile networks, emerging Internet of Things (IoT), Cloud systems, and soon for the future 5G/6G networks. The future networks will reach a whole new level of self-awareness, self-configuration, self-optimization, self-recovery and self-protection. This volume consists of 28 chapters, based on recent research on IBN.The volume is a collection of the most important research for the future intent-based networking deployment provided by different groups of researchers from Ukraine, Germany, Slovak Republic, Switzerland, South Korea, China, Czech Republic, Poland, Brazil, Belarus and Israel. The authors of the chapters from this collection present in depth extended research results in their scientific fields.The presented contents are highly interesting while still being rather practically oriented and straightforward to understand. Herewith we would like to wish all our readers a lot of inspiration by studying of the volume!
This book describes cloud computing as a service that is "highly scalable" and operates in "a resilient environment". The authors emphasize architectural layers and models - but also business and security factors.

A guided tour of the physical Internet, as seen on, above, and below the city’s streets What does the Internet look like? It’s the single most essentail aspect of modern life, and yet, for many of us, the Internet looks like an open browser, or the black mirrors of our phones and computers. But in Networks of New York, Ingrid Burrington lifts our eyes from our screens to the streets, showing us that the Internet is everywhere around us, all the time—we just have to know where to look. Using New York as her point of reference and more than fifty color illustrations as her map, Burrington takes us on a tour of the urban network: She decodes spray-painted sidewalk markings, reveals the history behind cryptic manhole covers, shuffles us past subway cameras and giant carrier hotels, and peppers our journey with background stories about the NYPD's surveillance apparatus, twentieth-century telecommunication monopolies, high frequency trading on Wall Street, and the downtown building that houses the offices of both Google and the FBI's Joint Terrorism Task Force. From a rising star in the field of tech jounalism, Networks of New York is a smart, funny, and beautifully designed guide to the endlessly fascinating networks of urban Internet infrastructure. The Internet, Burrington shows us, is hiding in plain sight.

Increase profitability, elevate work culture, and exceed productivity goals through DevOps practices. More than ever, the effective management of technology is critical for business competitiveness. For decades, technology leaders have struggled to balance agility, reliability, and security. The consequences of failure have never been greater―whether it's the healthcare.gov debacle, cardholder data breaches, or missing the boat with Big Data in the cloud. And yet, high performers using DevOps principles, such as Google, Amazon, Facebook, Etsy, and Netflix, are routinely and reliably deploying code into production hundreds, or even thousands, of times per day. Following in the footsteps of The Phoenix Project, The DevOps Handbook shows leaders how to replicate these incredible outcomes, by showing how to integrate Product Management, Development, QA, IT Operations, and Information Security to elevate your company and win in the marketplace.
