Configuration Management, Continuous Integration, Continuous Delivery Revealed

Greg Ramsey (Enterprise Mobility #ITDevConnections

Configuration Management, Continuous Integration, Continuous Delivery Revealed Session Description PowerShell Desired State Configuration, Chef, Puppet, Anisble, Orca, and the list goes on and on. Join this session to understand how these tools should (or will) fit into your environment, and how they're different than System Center Configuration Manager. We'll discuss infrastructure as code, and how these tools help move your business towards DevOps.

Configuration Management, Continuous Integration, Continuous Delivery Revealed What is Configuration Management? Configuration Management (CM) provides the operational agility, efficiency and insight needed to proactively manage dynamic infrastructure. This solution helps define the desired state, and then CM enforces it, while making it easy to provision, configure, and manage your entire IT infrastructure including servers, network devices, storage, applications and services. #ITDevConnections

Configuration Management, Continuous Integration, Continuous Delivery Revealed What is Continuous Integration? Continuous integration (CI) is the practice of merging all developer working copies to a shared mainline several times a day. How: Maintain a code repository Automate the Build Make the build self testing Test in a clone of Prod Automate Deployment #ITDevConnections

Configuration Management, Continuous Integration, Continuous Delivery Revealed What is Continuous Delivery? Continuous delivery (CD) is a software engineering approach in which teams produce software in short cycles, ensuring that the software can be reliably released at any time. How: Create a deployment pipeline Visibility (building, deploying, testing, releasing) Feedback (learn of problems asap) Continually deploy (fully automated, any version, any environment) #ITDevConnections

Configuration Management, Continuous Integration, Continuous Delivery Revealed What is DevOps? DevOps Toolchain Code development and review Build using version control Test results and determine performance Package application Release automation, change mgmt Configure Infrastructure, IaC Monitor Applications and perf monitoring #ITDevConnections DevOps promotes a set of processes and methods for thinking about communication and collaboration between development, QA, and IT operations

Configuration Management, Continuous Integration, Continuous Delivery Revealed #ITDevConnections “Humans are great at innovation, and simplification. Humans stink at repeatability and consistency.” - Greg Ramsey -

Configuration Management, Continuous Integration, Continuous Delivery Revealed Configuration Management #ITDevConnections Key Benefits Greater agility and faster problem resolution Complete auditability Standardize infrastructure and application configuration management Enhanced system reliability

Configuration Management, Continuous Integration, Continuous Delivery Revealed Configuration Management Define desired state using a powerful, declarative language True simulation of changes before deployment. Then move through nonprod to prod. Enforce desired state by remediating configuration drift Gain insight into your infrastructure – identify configuration drift. Speed Consistency Insight
