Improve your Software Development – Continuous Deployment with Docker – Part 1: Introduction and motivation
Introduction
Hay steemit-community,
As I wrote in my introduction post, my first articles here will be a full tutorial for Continuous Delivery starting at the bottom – So here we go!
This is the first part in which I want to motivate the usage of Continuous Deployment (CD) and tell you what you can expect from the further parts I will create.
By the way, if you want to know more about me, read my first post :)
Motivation
You may ask yourself, what the heck is CD and why should I invest the time I could use to improve my software with installing and configuring tools.
CD is basically a collection of tools and techniques to automate everything from the the check in of a code change into version control, to a new version in production. If done right, CD allows improving the quality of your software by a bunch of automated tests and short release cycles.
The reason why you should use it is simple: If you want to start getting serious with the product you have created, it has to have a high quality. No one in this world likes Software with bugs and in most cases there are 10 other products for the same problem, so the most customers just switch the product if they are pissed off by the bugs of your software.
Chapters
As the topic is very complex, I will split this tutorial in several parts. In the next part, we will begin to create a very simple example-application in Java, as I hope that most of you can write Java code. We will then add the build-management-tool Maven to the project, which we will need later to automate our first unit tests.
The next chapter will teach some basic concepts of test driven development. This technique can be used to ensure high code coverage and well tested software.
As we no longer want to run all the steps manually, we will start to create a Continuous Integration pipeline with a CI-Server that runs our tests on every code change.
We than reach the tricky part: Docker. We will learn how to create and deploy Docker images of our Software.
In the last part I will talk about the blue/green deployment, which could be used for a zero-downtime deployment and a last final test in a production like environment.

Part 2: An example project using Maven as an automation tool
Part 3: Test driven development
Part 4: Continuous Integration
Part 5: Docker basics
Part 6: Docker Swarm
Part 7: Blue/Green Deployment
There is a good company for you https://exoft.net/. Be completely sure that this agency will provide you with the best solutions on the market. If you want to realize some of your ideas and concepts, but you're too shy to seem like a fool, just ask them and they will find good solutions for every one of your demands.
Of course, in plain words, software development involves all the tasks that bring a software project from conception to production delivery. IBM Research clarified this definition: “Software development refers to a set of computer science activities dedicated to the process of creating, designing, deploying and supporting software.” Software development is often conducted by software developers, software engineers, and programmers. These roles can overlap, and the dynamics between them can vary across development departments and communities. There are the five most commonly used software development processes. You should understand each of them to see their differences and choose the right one for your business. Knowing what’s urgent to do and what you can do later is crucial. It takes a lot of time, effort, and headaches to create software, so if you can set priorities for everything you have to do, it’s beneficial.
dez1337, great analytics I gotta say. Improving software systems - is pretty important thing for any corporation, isn't it? It's actually not so easy to find some specific software applications for different systems, even if we talk about computers which can be built on well-known OS. When we've faced some issues with software in our company, the only company that helped us with it was Miquido ( found them here: https://www.miquido.com/ ), with their dev professionals, who have implemented software features that we've asked and made it the shortest terms.
It's great if you understand business software and apps and can change something in them, fix them, and so on. I trust only experienced developers in everything related to software, so it’s easier for me to find experienced ios developers for hire at this site. By the way, it’s convenient that now I don’t have to spend time searching and hiring specialists on my own. Saves a lot of time.
Great read on integrating Docker into the continuous deployment pipeline for more efficient software development! The benefits of containerization and automated workflows are clear. Additionally, embracing cloud computing in mobile app development can take this to another level: [https://attractgroup.com/blog/cloud-computing-in-mobile-app-development/]. Combining Docker with cloud strategies can really streamline production!
