The DevOps tool ¶
See also
In the next five years, our world will continue to become more software-defined and as developers begin to adopt DevOps practices, they will need tools that accelerate workflow and simplify the development process .
While DevOps has a great deal of potential, organizations tend to continue to have technology and role complexity with both developers and operators with some degree of incremental DevOps technology at the intersection between the two.
We believe this divide will begin to close and developers and operators will both find themselves with more seamless options that allow them to move faster from idea to production.
GitLab: 2018 is the year for open source and DevOps ¶
The demand for DevOps continues to grow, even though there are still challenges created by outdated tools and company resistance to change .
According to the report, only 23 percent identify DevOps as their development methodology. However, IT management has named DevOps as one of the top three areas of investment in 2018, indicating that the number of DevOps adopters is sure to grow this year.
GitLab found that most developers are in agreement that DevOps workflows save time during the development process. Teams that have adopted DevOps have confirmed that there is an increase in productivity, allowing them to spend at least 50 percent of their time on new work.
Build, Test, Store and Distribute Docker Containers with GitLab ¶

The use of Docker containers has exploded (at least within Web Development) and therefore we have a whole bunch of new tools that can be used to manage the DevOps process. However, there are a massive range of tools that can be used to achieve all of these. Be it Git hosting (GitHub, Bitbucket); Continuous Integration and Delivery and Build Tools (Jenkins, CircleCI, Drone); Docker Registry (Docker EE, Quay.io), or a range of other add-on tools, there sometimes seem as many new, great products in the DevOps area as there are Javascript frameworks(!).
However, I feel that GitLab offers a single solution that is able to compete with other established tools and potentially enable you to have a full professional delivery platform for free (within some restrictions on numbers).
It’s critical for organizations to use the latest development tools ¶

2017 ¶
Over the last decade, distributed version control systems, like Git, have gained popularity and are regarded as the most important development tools by developers.
Although the learning curve can pose a challenge, developers told us that Git enhances their ability to work together and ship faster, suggesting that managers have a real incentive to help their teams over the initial hill imposed by the transition to Git.
With the full history of the repository stored on each developer’s machine, using Git makes commits, merges and other commands much faster, even enabling developers to work offline.
Upgrading your source code management solution to a distributed version control system is the first step toward building a flexible working environment that can support modern development teams, but moving away from legacy systems and tools can be a daunting prospect .
Git for developers ¶
Feature Branch Workflow ¶
See also
One of the biggest advantages of Git is its branching capabilities.
Unlike centralized version control systems, Git branches are cheap and easy to merge .
This facilitates the feature branch workflow popular with many Git users.
Feature branches provide an isolated environment for every change to your codebase.
When a developer wants to start working on something—no matter how big or small—they create a new branch. This ensures that the master branch always contains production-quality code.
Using feature branches is not only more reliable than directly editing production code, but it also provides organizational benefits.
They let you represent development work at the same granularity as the your agile backlog. For example, you might implement a policy where each Jira ticket is addressed in its own feature branch.
Distributed Development ¶
In SVN, each developer gets a working copy that points back to a single central repository .
Git, however, is a distributed version control system .
Instead of a working copy, each developer gets their own local repository, complete with a full history of commits.
svn versus git ¶
Having a full local history makes Git fast , since it means you don’t need a network connection to create commits, inspect previous versions of a file, or perform diffs between commits.
Distributed development also makes it easier to scale your engineering team.
If someone breaks the production branch in SVN, other developers can’t check in their changes until it’s fixed.
With Git, this kind of blocking doesn’t exist .
Everybody can continue going about their business in their own local repositories.
And, similar to feature branches, distributed development creates a more reliable environment. Even if a developer obliterates their own repository, they can simply clone someone else’s and start anew.
