The Essential DevOps Terms You Need to Know
By Alexander Moss-Bolaños

New to the DevOps world and looking to get a grip on some of the industry’s key terms? Search no further. This short list of Essential DevOps Terms will serve as a foundation from which you can build your understanding of the industry’s tools and methodologies.


DevOpsPic

Agile
A precursor to DevOps, Agile is a software development and, more broadly, business methodology that emphasizes short, iterative planning and development cycles to provide better control and predictability and support changing requirements as projects evolve.

DevOps
DevOps
(development and operations) is a software development phrase used to describe a type of agile relationship between Development and IT Operations. The goal of DevOps is to improve communication, collaboration, and processes between the various roles in the software development cycle, in order to improve and speed up software delivery.

Continuous Delivery
Continuous Delivery (CD) is a set of processes and practices that radically removes waste from your software production process, enables faster delivery of high-quality functionality and sets up a rapid and effective feedback loop between your business and your users.

Continuous Integration
Continuous Integration (CI) is a development practice that requires developers to integrate code into a shared repository several times a day. Each check-in is then verified by an automated build, allowing teams to detect problems early.

Microservices
Microservices are software architecture design pattern, in which complex applications are composed of small, independent processes communicating with each other using language-agnostic APIs. These services are small, highly decoupled and focus on doing a small task.

Release Orchestration
Release Orchestration is the use of tools like XL Release which manage software releases from the development stage to the actual software release itself.

Provisioning
Provisioning is the process of preparing new systems for users (in a Continuous Delivery scenario, typically development or test teams). The systems are generally virtualized and instantiated on demand. Configuration of the machines to install operating systems, middleware etc. is handled by automated system configuration management tools, which also verify that the desired configuration is maintained.

Configuration Management
A term for establishing and maintaining consistent settings and functional attributes for a system. It includes tools for system administration tasks such as IT infrastructure automation.

Deployment Management
Deployment Management aims to plan, schedule and control the movement of releases to test and live environments.

Test-Driven Development (TDD)
A development practice in which small tests to verify the behavior of a piece of code are written before the code itself. The tests initially fail, and the aim of the developer(s) is then to add code to make them succeed. Check out Xebia Labs’ testing dashboard and analytics tool here.

Build Automation
Tools or frameworks that allow source code to be automatically compiled into releasable binaries. Usually includes code-level unit testing to ensure individual pieces of code behave as expected.

Unit Testing
Code-level (i.e., does not require a fully installed end-to-end system to run) testing to verify the behavior of individual pieces of code. Test-driven deployment makes extensive use of unit tests to describe and verify intended behavior.

Application Release Automation (ARA)
Tools, scripts or products that automatically install and correctly configure a given version of an application in a target environment, ready for use.

Canary Release
A go-live strategy in which a new application version is released to a small subset of production servers and heavily monitored to determine whether it behaves as expected. If everything seems stable, the new version is rolled out to the entire production environment.

Dark Launch
A go-live strategy in which code implementing new features is released to a subset of the production environment but is not visibly, or only partially, activated. The code is exercised, however, in a production setting without users being aware of it.

Regression Testing
Testing of the end-to-end system to verify that existing functionality has not been negatively impacted by changes to the application.

IoT & Smart Cities Stories
The deluge of IoT sensor data collected from connected devices and the powerful AI required to make that data actionable are giving rise to a hybrid ecosystem in which cloud, on-prem and edge processes become interweaved. Attendees will learn how emerging composable infrastructure solutions deliver the adaptive architecture needed to manage this new data reality. Machine learning algorithms can better anticipate data storms and automate resources to support surges, including fully scalable GPU-c...
Machine learning has taken residence at our cities' cores and now we can finally have "smart cities." Cities are a collection of buildings made to provide the structure and safety necessary for people to function, create and survive. Buildings are a pool of ever-changing performance data from large automated systems such as heating and cooling to the people that live and work within them. Through machine learning, buildings can optimize performance, reduce costs, and improve occupant comfort by ...
The explosion of new web/cloud/IoT-based applications and the data they generate are transforming our world right before our eyes. In this rush to adopt these new technologies, organizations are often ignoring fundamental questions concerning who owns the data and failing to ask for permission to conduct invasive surveillance of their customers. Organizations that are not transparent about how their systems gather data telemetry without offering shared data ownership risk product rejection, regu...

Poor data quality and analytics drive down business value. In fact, Gartner estimated that the average financial impact of poor data quality on organizations is $9.7 million per year. But bad data is much more than a cost center. By eroding trust in information, analytics and the business decisions based on these, it is a serious impediment to digital transformation.
Digital Transformation: Preparing Cloud & IoT Security for the Age of Artificial Intelligence. As automation and artificial intelligence (AI) power solution development and delivery, many businesses need to build backend cloud capabilities. Well-poised organizations, marketing smart devices with AI and BlockChain capabilities prepare to refine compliance and regulatory capabilities in 2018. Volumes of health, financial, technical and privacy data, along with tightening compliance requirements by...
Predicting the future has never been more challenging - not because of the lack of data but because of the flood of ungoverned and risk laden information. Microsoft states that 2.5 exabytes of data are created every day. Expectations and reliance on data are being pushed to the limits, as demands around hybrid options continue to grow.

Enterprises have taken advantage of IoT to achieve important revenue and cost advantages. What is less apparent is how incumbent enterprises operating at scale have, following success with IoT, built analytic, operations management and software development capabilities - ranging from autonomous vehicles to manageable robotics installations. They have embraced these capabilities as if they were Silicon Valley startups.
As IoT continues to increase momentum, so does the associated risk. Secure Device Lifecycle Management (DLM) is ranked as one of the most important technology areas of IoT. Driving this trend is the realization that secure support for IoT devices provides companies the ability to deliver high-quality, reliable, secure offerings faster, create new revenue streams, and reduce support costs, all while building a competitive advantage in their markets.
