Ansible Automation provides the glue needed to bridge together all layers of an enterprise architecture. It includes both Ansible Engine and Ansible Tower. Ansible Engine is a simple, cross-platform automation tool for individual engineers, administrators, and operators. Ansible Tower is the enterprise automation platform for controlling, managing, integrating, securing and scaling out execution of Ansible Engine.

  • Automating the F5 BIG-IP Platform with Ansible | F5 Technical White
    + TECHNICAL WHITE PAPER Automating the F5 BIG-IP Platform with Ansible TECHNICAL WHITE PAPER Automating the F5 BIG-IP Platform with Ansible Contents Introduction 3 The programmable network 3 A comprehensive joint solution 4 Use case: configure an HTTPS application on the BIG-IP platform 4 Conclusion 9 2 TECHNICAL WHITE PAPER Automating the F5 BIG-IP Platform with Ansible Introduction “The key drivers for the use of DevOps-related frameworks and toolsets remain scalability and reduction of operational expenses.”1 Traditionally, organizations deploy infrastructure and applications using a combination of various documents such as deployment guides along with many manual processes and operations. It’s a time-consuming approach that doesn’t align with ever-increasing requirements for speed and agility. The need to deploy full application stacks and services more quickly and more often in a repeatable manner has driven both development and operational teams toward automation and orchestration. In addition to enabling organizations to better manage applications, infrastructure deployments, and the process of provisioning and de-provisioning, automation reduces the amount of IT resources required and ensures increased reliability, efficiency, and agility. The programmable network Through a deep understanding of best practices for networking and application delivery, F5 empowers organizations to take advantage of the benefits of automation and programmability as they configure and manage devices on the BIG-IP platform. Both the hardware and virtual editions of F5 Application Delivery Controllers (ADCs) feature flexible and programmable management, control and data planes. F5 ADCs achieve programmability through the following features: 1. Traffic Management Shell (tmsh): Allows complete access to configure system features and set up and manage network elements.

  • Automating the Enterprise with Ansible
    AUTOMATING THE ENTERPRISE WITH ANSIBLE Dustin Boyd Solutions Architect September 12, 2017 EVERY ORGANIZATION IS A DIGITAL ORGANIZATION. Today, IT is driving innovation. If you can’t deliver software fast, your organization can’t meet the mission, period. Digital organizations are essentially software. If they expect to thrive in a digital environment, they must have an improved competence in software delivery. Gartner 2015 2 COMPLEXITY KILLS PRODUCTIVITY. Complexity is the enemy of innovation, which is why today’s enterprises are looking to automation and DevOps tools and practices. DevOps can help organizations that are pushing to implement a bimodal strategy to support their digitalization efforts. Gartner 2015 3 WHEN YOU AUTOMATE, YOU ACCELERATE. Ansible loves the repetitive work your people hate. It helps smart people do smarter work. All with fewer errors and better accountability. Automation can crush complexity and it gives you the one thing you can’t get enough of… time. 4 “Ansible delivers DevOps to a broader class of enterprise users that include those inside the business units and teams where agile practices and fast provisioning of infrastructure are in demand.” JAY LYMAN, 451 RESEARCH – NOV 2013 GARTNER COOL VENDOR 2015 “Previous vendors in this [DevOps] market often require unique programming skills. Ansible’s simple language reduces the barrier to adoption and opens it up to a variety of skill sets…” 5 AUTOMATION = ACCELERATION “With Ansible Tower, we just click a button and deploy to production in 5 minutes. It used to take us 5 hours with 6 people sitting in a room, making sure we didn’t do anything wrong (and we usually still had errors).
