Software certifications demonstrate a level of skill and expertise in a particular software to employers and peers. Given the variety of systems involved in data centers, many data center admins look to IT standards organizations and vendors to determine which certifications they might pursue.
Such organizations and vendors offer many certifications and training courses for software systems and processes, such as container management software, DevOps or automation.
Red Hat Certified Specialist in Virtualization. Admins using Red Hat products can use this certification to demonstrate their skills, knowledge and abilities with regard to deploying and managing virtual infrastructure. This certification covers VM creation, clustering, pooling and virtualization templates, along with other essential management tasks. The exam costs $400, and the recommended -- but not required -- training course costs $3,800.
Many DevOps teams use container software such as Kubernetes, Docker and Mesos to optimize their development processes. Container software has different requirements and architectures that pose unique challenges to data center admins. For example, container software requires low latency and high bandwidth connections to related servers because it runs multiple microservices concurrently in a single application. Individual servers can contain dozens of containers, which leads to significant network performance management problems and can require complex upgrades.
Certifications in container software give admins insights into designing data centers to meet the requirements of container infrastructure. Container management software includes Docker, Kubernetes and several AWS and Google container services.
