1. Microsoft Certified: Azure Solutions Architect Expert 

Many businesses operate within Microsoft ecosystems, making Microsoft certifications extremely valuable and sought after. However, Microsoft has overhauled its certification processes in recent years, replacing broad certificates like Microsoft Certified Solutions Expert with a wider variety of role-based certification options divided into the following roles:

• Security engineer
• DevOps engineer
• Functional consultant
• Developer
• Administrator
• Solutions architect 

Certifications come in beginner, intermediate, and expert levels, based on applicants’ experience. 

Various system administrators may find some Microsoft certifications more advantageous than others. However, the Azure Solutions Architect Expert is the most in-demand certification for a SysAdmin with IT operation experience.  

The Azure Solutions Architect Expert certification is ideal for someone with extensive experience using Azure to solve problems and make decisions for a business’s tech needs. Candidates must have experience with every level of IT operations as well as DevOps. Candidates will be tested on their knowledge and ability to design solutions for data storage, identity, infrastructure and more using Azure.

3. RHCE: Red Hat Certified Engineer

In the realm of Linux system administrator certifications, Red Hat certifications stand out. Red Hat’s more senior-level certifications are especially popular among IT professionals and the firms that hire them.

The RHCE is considered a high-level credential that’s not easy to obtain. Candidates must first obtain the Red Hat Certified System Administrator (RHCSA) credential. The RHCE credential expands the RHCSA’s understanding of automation in multisystem environments. Candidates must then pass an intense, demanding, four-hour, hands-on, performance-based exam. Those who earn the RHCE can go on to earn the Red Hat Certified Architect (RHCA) in Infrastructure credential.

Candidates can choose a path based on Red Hat Enterprise Linux 7 or Red Hat Enterprise Linux 8. RHCE certification is valid for three years from the date the certification was achieved. To maintain the certification, a credential holder must pass any RHCA exam or pass the RHCE certification exam again before the end of the three years.
