We like Linux. Our preferred flavor is Ubuntu, but that doesn't mean we can't handle your Red Hat, CentOS, or Oracle Linux needs. We can build you a great continuous integration system using Jenkins and GitHub, GitLab, and have it roll out your applications into the Amazon, Azure, or Google Cloud, or run them on your own servers.
We can build you an entire HashiCorp Terraform Pipeline, allowing you to scaffold all of your critical infrastructure as code instead of costly labor-intensive tasks such as manually configuring disk sizes, database versions, and software releases.
We also do UNIX, as in Sun Solaris. If you've never heard of it, then don't worry about it, but if you need someone to manage your Oracle Database Server running any version of Solaris from 2.5.1 to Oracle Solaris 11.4, we got this.
