<h3>What is Continuous Deployment?</h3>


Continuous deployment is a software development practice where each code change moves through automated tests resulting in successful application builds and is put into production stage through multiple production deploys. 

This practice enables programmers to create, test, and deploy high-quality apps more quickly.

The key advantage of </span><a href="https://www.agilealliance.org/glossary/continuous-deployment/#q=~(filters~(postType~(~'page~'post~'aa_book~'aa_event_session~'aa_experience_report~'aa_glossary~'aa_research_paper~'aa_video)~tags~(~'continuous*20deployment))~searchTerm~'~sort~false~sortDirection~'asc~page~1)"><span style="font-weight: 400;">continuous deployment</span></a><span style="font-weight: 400;"> is a reduced lead time: you get more quality apps faster and with minimized risks. 

What’s important, you receive user feedback on each new change or feature so you can effectively hold A/B testing, understand user needs and preferences, and implement changes required for product success.


<h3>Introduction to Docker</h3>

 
Docker is an </span><a href="https://en.wikipedia.org/wiki/Open-source_software"><span style="font-weight: 400;">open-source</span></a><span style="font-weight: 400;"> tool allowing an automated application deployment and “collaborating” with the cloud, Linux, and Windows providers. 

Docker works as follows: it packs applications and their dependencies into isolated lightweight containers making them easily portable to any infrastructure.

There are many Docker advantages, first and foremost the acceleration of custom mobile or web app development process, reduced costs, more quality and secure applications. By taking Docker advantages, programmers significantly reduce the time between writing their code and moving the app into production.
 

<h3>With Docker, you get the ability to:</h3>


- Automate software development process (including deployment) by 13X

- Deploy applications on the cloud or on-premises depending on your needs
Remove the “works on my machine” problem

- Develop secure applications with minimized risks due to embedded security capabilities and configurations out of the box

- Reduce costs thanks to optimized infrastructure use and more fast software development

- Easily manage your infrastructure in the same way you manage applications


 

Now Docker is the only container platform enabling developers to create, deploy, and manage their applications from the dev to production stage and run them either on cloud or on-premises.
