What can you expect from popular, open-source tools and technologies in 2019?

An ever-expanding cloud making it possible to work in an app anytime, anywhere.

Tools for software development and maintenance are rapidly evolving, thus freeing engineers from dull, error-prone tasks.

Automation is key to progress: instruments provide automation.

New features help manage large numbers of objects. IDEs help maintain a large codebase; orchestration tools make it possible to orchestrate huge numbers of containers.

Check out the most beneficial open-source technologies. The list is divided into two parts:

Part 1) DevOps’ instruments (below)

Part 2) Best open-source development tools.

IT Craft development and operations teams either use or plan to use these technologies for their projects.


As Kohsuke Kawaguchi, Jenkins’ creator, commented on his blog: “2018 was a year of innovation.” The Jenkins team worked hard throughout 2018 to support the software delivery automation trend. Their focus was transforming Jenkins into a general-purpose CI/CD engine.

Jenkins must evolve into a must-have tool that gently supports the efforts of all those who seek a timely, smooth delivery.

Here are the major enhancements:

Jenkins X – designed to harmonize orchestration and provide automated CI/CD for Kubernetes. Plus, serverless Jenkins with Jenkins X is now available. What does this mean? Improved scalability, more efficient disk space utilization, and reduced cloud expenses.

Jenkins Configuration as Code Plugin – used to reproduce or restore a full environment based on human-readable files.

Evergreen – an automatically updated distribution system for Jenkins that can be described as a pre-assembled collection of Lego bricks used for CI/CD pipeline.

The Jenkins team is not going to ease up in 2019. They will continue to provide more automation tooling for successful code delivery—and will, without doubt, succeed: the active Jenkins’ community keeps growing.


Kubernetes, a Linux container orchestration platform, keeps trending.

Its popularity seems incredible: Kubernetes is supported by Google and enjoys a large community. Even more, Kubernetes has become a de facto standard in managing containerized workloads and services.

Kubernetes manages all sorts of apps and rapidly growing ecosystems as it provides “building blocks” that DevOps teams can use further to construct and configure their own unique and flexible environments—and deploy containers at scale. No need to fritter away excess effort on each individual container.

DevOps Instruments

Major cloud hosting providers, such as AWS, Azure, GPC, IBM Cloud, OpenStack and others, support Kubernetes because of its exceptional extend system. Also, Kubernetes can run on a desktop, in the cloud, or on any kind of in situ servers.

In 2019, we can expect nothing but growth in popularity and wider adoption of Kubernetes for many different projects—as long as Kubernetes makes some progress on its general user friendliness.

Kubernetes demands time for learning. Running large-sized clusters on Kubernetes is quite a task. As mentioned above, it is rather more a set of various sophisticated instruments with no formalized support structure than a systematized, turnkey package.

When Kubernetes provides improved capabilities to run and manage multi-cluster and multi-cloud environments, it will be the clear winner in both startup and enterprise categories.


2018 was a fruitful year for GitLab, a Git-repository manager known for global team power who contribute remotely from all over the world.

GitLab started in 2011, and continues to expand its services, becoming one of the most wide-spread software, alongside its competitor GitHub, to handle the entire CI/CD pipeline.

The exciting news for GitLab was Microsoft’s acquisition of GitHub in June 2018: many GitHub-hosted projects rushed to GitLab almost overnight.

However, there was much more astonishing news keeping GitLab among leaders in the field.

In August 2018, Drupal, a popular CMS platform, happily migrated to GitLab as a result of its “Drupal Flow” policy. Drupal started looking for a reliable, third-party provider; however, it had serious roadblocks preventing integration to the GitLab platform. The GitLab team worked hard to solve those issues while also providing code collaboration tools.

The result? Over 44,000 Drupal projects moved to GitLab.

Also, in the summer of 2018, GitLab introduced Meltano, a special service for big data handling. With Meltano’s help, data teams get a full package covering their needs for data analysis tools.


And there are more benefits for DevOps. The latest version, GitLab 11.6, introduces GitLab Serverless to solely build, deploy, and manage server workloads while not being encumbered to any specific cloud provider.

Two more benefits: GitLab introduced its own Web IDE in order to edit multiple files and loads of commits. And, more importantly, GitLab supports Kubernetes to provide more productive native cloud development.

We can expect GitLab to successfully compete in 2019 and retain its leading position among CI/CD tools.


Thank you for reading this. We strongly believe that these analyzed instruments make seamless integration possible at every development stage. They ensure consistency throughout software development and a delivery pipeline saving precious resources at all stages of the development cycle.

And, speaking about the power of automation, the Cloud does not forgive excessive resource consumption. Every non-optimal server configuration can cost its owner considerable money to maintain.
