Continuous Delivery (CD)
A MODERN DEVELOPMENT CULTURE FOR TODAY AND TOMORROW’S CHALLENGES
At Dev IQ, we stay current with the latest methodologies, principles, and techniques to help us do our job better and help you get your product into use faster and safer. A key element of our workflow is to establish a Continuous Delivery Pipeline, whether we are building a product from scratch or modernizing an existing application.
It is the ability to get changes of all types—including new features, configuration changes, bug fixes and experiments—into production, or into the hands of users, safely and quickly in a sustainable way.Jez Humble

Continuous delivery begins with small teams, working to deliver discrete product functions. Product managers work closely with technical and operational teams to monitor KPIs and deliver real-time user feedback, enabling iterative improvements to be delivered rapidly. Automated testing improves efficiency, and limited releases of new features to select user groups enable the execution of Lean experiments while minimizing overall risks, as issues can be quickly resolved, by fixing forward fast, without significant impact on the user experience. Dual production instances are maintained to ensure stability and successful delivery to the end users.
The benefits of continuous delivery include:
- Rapidly accelerated speed-to-market of products and product updates
- Reduced costs & risks
- Greatly enhanced customer relationships as products are constantly improved.
“On top of having automated testing, you also have an automated release process; you can deploy at any point of time by clicking on a button.”

Our Continuous Delivery Pipeline (CDP)
An easy way to understand our CDP is imagining a production line or hydraulic system of pipes, valves, pumps, and tanks. Code is the fluid that moves from one end to the other, being refined and transformed until it reaches the user. Once this pipeline and its components are in place, any changes such as new features or fixes can be made almost immediately, without the need for shutdowns or downtime.
We have helped our clients reduce significant costs and implement new features without disrupting their operations or affecting users’ experience. We have also created an illustrated diagram of our Continuous Delivery Pipeline to help explain the concepts, with a style based on a certain popular plumber.

Rather than delivering compartmentalized chunks of code in phases, Continuous Delivery pushes feature-focused, iterative microService developments. Because the changes pushed are smaller, the testing process is rapid and depends on real user feedback.
Groups of microServices are deployed to automated test environments that deliver rapid fail notifications and successful deployments, increasing overall stability.
The outcomes of testing
Containerization enables the architectural pattern for microService delivery and optimized testing.
The code deliveries for each microService enter into the Continuous Integration system – taking any dependencies into account – which transforms them or packages them into a container. A container includes the code and environment for a microService delivery.
After passing rigorous automated testing,
A lightweight alternative to full machine virtualization that involves encapsulating an application in a container with its own operating environment.
IoT, like many emerging technologies, is prone to misuse and abuse. Securing devices can be a pain, but visionary companies are working together to simplify and truly secure IoT, unlocking its potential.
