You will be exposed to various networking strategies that are stopping your organization from scaling new projects quickly.You will see how SDN and APIs are influencing DevOps transformations, which will in turn help you improve the scalability and efficiency of your organizations networks operations. You will also find out how to leverage various configuration management tools such as Ansible, to automate your network.The book will also look at containers and the impact they are having on networking as well as looking at how automation impacts network security in a software-defined network.What you will learnLearn about public and private cloud networking using AWS and OpenStack as examplesExplore strategies that can be used by engineers or managers to initiate the cultural changes required to enable the automation of network functionsLearn about SDN and how an API-driven approach to networking can help solve common networking problemsGet the hang of configuration management tools, such as Ansible and Jenkins, that can be used to orchestrate and configure network devicesSetup continuous integration, delivery, and deployment pipelines for network functionsCreate test environments for network changesUnderstand how load balancing is becoming more software defined with the emergence of microservice applicationsAbout the AuthorSteven Armstrong is a DevOps solution architect, a process automation specialist, and an honors graduate in Computer and Electronic Systems (BEng) from Strathclyde University in Glasgow.He has a proven track record of streamlining companys development architecture and processes so that they can deliver software at pace. Specializing in agile, continuous integration, infrastructure as code, networking as code, Continuous Delivery, and deployment, he has worked for 10 years for leading consulting, financial services, benefits and gambling companies in the IT sector to date.After graduating, Steven started his career at Accenture Technology solutions as part of the Development Control Services graduate scheme, where he worked for 4 years, then as a configuration management architect helping Accentures clients automate their build and deployment processes for Siebel, SAP, WebSphere, Weblogic, and Oracle B2B applications.During his time at Accenture, he worked within the development control services group working for clients, such as the Norwegian Government, EDF Energy, Bord Gais, and SABMiller. The EDF Energy implementation led by Steven won awards for best project industrialization and best use of Accenture shared services.After leaving Accenture, Steven moved on to the financial services company, Cofunds, where he spent 2 years creating continuous integration and Continuous Delivery processes for .Net applications and Microsoft SQL databases to help deploy the financial services platform.After leaving Cofunds, Steven moved on to Thomsons Online Benefits, where he helped create a new DevOps function for the company.
