Earning a certification can help a system administrator move forward in their career, but it can be tough to choose from the many options available.

  • Certification programs help system administrators stand out from their peers while expanding and validating their skills. 
  • Certification training and testing help IT professionals earn professional credibility and more power to direct and control their career paths. 
  • Numerous certifications are available, but several are exceptionally valued and respected. 
  • This article is for system administrators and IT professionals who want to expand their knowledge and professional credibility through certification programs.

System administrators are the glue holding together business operations, ensuring smooth-running IT infrastructures. The role requires in-demand career skills that range from server and client configuration and maintenance to access controls, network services and application resource requirements. SysAdmins may even work with more user-facing products, like directory and name services, network addressing, database services, web and desktop applications, and email. They’re often the company “tech expert” – sometimes at several organizations simultaneously. 

System administrator certifications help IT professionals navigate their career paths, expand their knowledge and demonstrate their expertise to managers and employers. SysAdmin certs may even help you secure managerial and executive level jobs and higher pay.

TipTip: If you’re a SysAdmin specializing in database services, consider exploring the best database certifications for database administrators and developers.

Beyond the top 5: More SysAdmin certifications

In addition to the five system administrator certifications we highlighted above, many other certification programs can help further the careers and professional development of IT professionals in system administration.

It makes sense to investigate the plethora of vendor-specific programs available for those who work with systems from companies like Brocade, Dell EMC, HPE, IBM, NetApp and Symantec. Many play into critical system specialty areas, such as storage, security and virtualization, while others offer a broad range of platforms for these and other technology areas. 

Here are some examples:

  • IBM Certified System Administrator MQ V9.1: IBM Certified System Administrator MQ V9.1 is for SysAdmins who cover admin activities such as migrating, configuration, availability, performance tuning and problem determination.
  • NetApp Certified Data Administrator (NCDA): NCDA is geared toward professionals who manage NetApp data storage controllers running the ONTAP operating system.
  • ServiceNow Certified System Administrator: ServiceNow Certified System Administrator is aimed at professionals adept at configuring, implementing and managing ServiceNow systems.

Vendor-neutral certification programs also offer a variety of interesting and potentially valuable credentials. For example, Linux Professional Institute certifications are well known and widely recognized in IT shops and operations that depend on Linux servers to handle their workloads. 

TipTip: Tech professionals may also want to consider certifications in adjacent fields, including big data certifications, starter cybersecurity certifications and project management certifications.
