DevOps is both a hot topic DevOps represents a new model for application development that requires deep. and an overused term today collaboration between software developers and IT operations This deep collaboration. There are almost as many is indicative of a culture focused on defining software with operations in mind and. definitions of DevOps as there automating the process of software delivery so that building testing and releasing. are people writing about it Is it, software happens rapidly frequently and reliably . a technology An organizational, construct A combination of the 1 1 Definitions.
two Is it the way Netflix and, Following are a set of foundational definitions for commonly used but variously. other internet based companies, defined in the industry terms associated with DevOps . develop software It depends on, who you read The purpose of. this paper is to provide guidance Term Definition, in the form of a set of concepts . a taxonomy and an overview of, DevOps Conceptually DevOps is that which is necessary to take an idea.
VMware s approach to DevOps feature code documentation whatever from inception through. delivery to a customer in the most expedient and sustainable way. possible , DevOps is most often applied in the context of software delivery and. refers to a model for application development focused on deep. collaboration between software developers and IT operations That. said the DevOps model can be applied to the development lifecycle of. anything with distinct development and operations components for. example infrastructure or IT services , Continuous Continuous Integration is the process of combining source code most. Integration likely from different developers or teams into a single application and. then typically running some automated suite of tests on the resulting. application This integration process runs continuously either polling. source control on a regular interval or triggered by code check in . Continuous Delivery Continuous Delivery is the process of packaging testing and storing an. application unit in a continuous fashion to be always ready to deliver. into production This extends the continuous integration process to. arrive at an application unit that has enough testing compliance and. validation that it is production ready , Continuous Some organizations or applications extend Continuous Delivery into. Deployment Continuous Deployment where the application is deployed into the. production environment automatically This typically requires robust. production validation mechanisms and comprehensive rollback. capability , Continuous Continuous Continuous, Integration Delivery Deployment. Validated, Code Build Test Artifact Test Increment Deploy.
W H I T E PA P E R 3, DEVOPS AND AGILE DEVELOPMENT. A VMWARE FIELD PERSPECTIVE, Term Definition, Delivery Pipeline The Delivery Pipeline refers to the stages of the process by which an application is delivered to production This. DevOps Pipeline will include as a minimum build integration testing and deployment but will likely also require code quality. scans security and compliance checks performance testing as well as progressing through different. environments , Delivery Pipeline The delivery pipeline tool chain is a collection of best of breed tools based on common industry patterns and. Tool Chain environment s requirements to support application development using C Java Python Go or other. programming languages See Section 3 Delivery Pipeline for a description of the delivery pipeline tool chain . Cloud Native Cloud Native Applications refers to applications architected and developed according to principles for optimally. Applications running and managing distributed applications on a cloud platform A good example of these principles are. those documented as the Twelve Factor App , The DevOps model is a key enabler of the Twelve Factor App governing principle which shares ideal practices. for app development paying particular attention to the dynamics of the organic growth of an app over time the. dynamics of collaboration between developers working on the app s codebase and avoiding the cost of. software erosion , The DevOps model can be seen as the required approach for developing Cloud Native Applications .
PaaS Platform as a service PaaS is a category of cloud computing services that provides a platform allowing. organizations to develop run and manage applications without the complexity of building and maintaining the. infrastructure typically associated with developing and launching an application for example Pivotal Cloud. Foundry , 1 2 Guiding Principles, Following is a set of DevOps guiding principles from a VMware perspective . DevOps Guiding Description, Principle, Dev Ops as one Traditionally Dev and Ops has been synonymous with us and them Developers developed software and. team handed it off hopefully through some defined release process to Infrastructure Operations I O for. production deployment and on going operations This approach was ripe with miscommunication and. misaligned expectations More often than not the first time I O became aware of a new application going into. production was during release review if there was one DevOps requires developers and I O to collaborate. extensively and continuously essentially becoming one team . While development and I O must collaborate extensively collaboration extends to actively including other. teams such as security for example at different points during the delivery pipeline . This also represents a significant cultural shift for traditional Dev and Ops a shift to a no blame culture based. on trust and deep collaboration , To carry this through the execution of the delivery pipeline employ an Agile methodology including both. development and I O activities in a single sprint plan . DevOps team is The DevOps team retains sole responsibility and accountability for the application it delivers and virtual. accountable and environment i e virtual machines and or containers in which it runs . responsible, W H I T E PA P E R 4, DEVOPS AND AGILE DEVELOPMENT. A VMWARE FIELD PERSPECTIVE, DevOps Guiding Description.
Principle, Shift to the left Instead of only focusing I O activities on deploying to and operating software in production I O activities. move into the delivery pipeline itself , Integrate capabilities into delivery pipeline such as early security and authentication testing as well as not only. opening up monitoring to the developers but I O actively monitoring application environment impacts as it. moves through the delivery pipeline and provide feedback to the developers . Automate the Automate all aspects of the delivery pipeline process to the greatest extent possible so that building testing . delivery pipeline and releasing software can happen rapidly frequently and reliably Automate everything that can be automated. and maintain manual steps only where regulatory or company policies require it . Immutable Infrastructure should be created once from original source code see Infrastructure as code and not. infrastructure manipulated after the fact particularly not with error prone manual processes . A closely linked concept any combined processes addressing the same infrastructure such as configuration. management should be idempotent so that repeated application does not result in errors or expected. changes , Infrastructure as Infrastructure should be treated as code keeping infrastructure definitions with application code in version. code control while providing the capability to deploy consistent production like environments throughout the. delivery pipeline stages This ensures consistency and provides an audit control point . Smaller more Each release introduces a small number of changes so production releases can be made more frequently and. frequent releases with less risk This also provides the opportunity to receive end user feedback and make adjustments more. quickly , 1 3 Infrastructure and Operations Implications. The DevOps guiding principles outlined above certainly impact I O The table below describes the key I O impacts . Note While the I O implications in the following table are presented in the context of supporting application development . they equally apply in the context of IT development such as for example when developing IT services scripts blueprints . automation and orchestration workflows and integration code IT can realize the same benefits when applying DevOps to. internal IT development as realized when applied to developing applications . DevOps Guiding Infrastructure Operations Implication. Principle, Dev Ops as one Understand the delivery pipeline and customize it to meet the needs of the application and its developers .
team Actively and continuously collaborate with development from planning through testing and release into. production in addition to on going operations , Collaboratively develop integrated sprint plans . Understand the application architecture and its implications for the virtualized environment in which it runs . DevOps team is Understand security audit and compliance requirements for the delivery pipeline as well as the virtual. accountable and environment in which the application will run in production . responsible Understand the impact of deploying the application and its virtual environment into production from a change. management perspective , W H I T E PA P E R 5, DEVOPS AND AGILE DEVELOPMENT. A VMWARE FIELD PERSPECTIVE, DevOps Guiding Infrastructure Operations Implication. Principle, Shift to the left Automate security compliance and operational readiness tests for early inclusion in the delivery pipeline . Actively work with developers to address operational considerations directly in application code . Provide open access by developers to monitoring and logging throughout the execution of the delivery. pipeline and as allowed by compliance policies in production . Work with developers to provide customized application level monitoring throughout the execution of the. delivery pipeline and in production , Actively monitor application virtualized environment throughout delivery pipeline and provide feedback to.
developers , Automate the Participate in delivery pipeline automation definition design and implementation . delivery pipeline Build compliance controls and audit capabilities into delivery pipeline automation . Provide self service on demand and or programmatic access to software defined infrastructure blueprints . and policies , Use same tools and code for operations activities in production as used in the delivery pipeline . Immutable Always modify the versioned definition of the virtual environment associated with the application and use the. infrastructure delivery pipeline to re deploy into production never update patch or modify in place in production . Infrastructure as Ensure ability to declare infrastructure as code and put it under version control . code Always define the virtualized environment as code and maintain the virtualized environment definition under. version control , Smaller more Work with IT change management and compliance auditors to focus governance on the version controlled. frequent releases definitions application code infrastructure as code blueprints policies etc of what is to be deployed as well. as the automated delivery pipeline itself rather than each application release unit . 1 4 Developer Implications, Just as for I O the DevOps guiding principles will impact developers as well The table below describes the key developer. impacts , DevOps Guiding Developer Implication, Principle.
