Cloud Certifications: GC Professional Cloud DevOps Engineer
Introduction
While Google Cloud’s revenue base is lower than that of Microsoft and Amazon, its growth rate is higher, according to a recent April 2020 analysis by cloudwars.co. This has put Google Cloud certifications in the spotlight lately, with employers showing increasing interest in certified GC professionals.

Compensation and Employment Outlook
In a 2020 Tech Salary Report by tech career website Dice, both Cloud Engineer and DevOps Engineer were amongst the top paying occupations, and also saw the biggest increases in salary and job postings between 2018 and 2019. The average salary for a DevOps Engineer was at US$117,478 in 2019, an increase of 5.2% from the previous year.
In addition, according to survey responses from the Global Knowledge 2019 IT Skills and Salary Report, 30% of Google Cloud certified professionals took on more responsibility or leadership roles at work.
The employment outlook and negotiation potential for a DevOps Engineer seems very promising as companies struggle to hire individuals with that kind of competence. In a Mashable infographic listing the top ten hardest hires for tech companies based on data from recruitment website Indeed, DevOps Engineer is listed at the top as the most difficult role for companies to fill. So it's reasonable to expect that within the next couple of years there will be further boosts in salary and career prospects for DevOps professionals. Paired with Google Cloud's growth, the Professional Cloud DevOps Engineer certification has great potential for future-proofing your career.
The Certification Path
This certification is one of GC's professional certifications, which are described by Google as certifications that "span key technical job functions and assess advanced skills in design, implementation, and management".
Since there are no prerequisites for taking the certification exam, and since it is not itself a prerequisite for any others, this certification is not part of a larger certification path. It could be the one certification to aim for if you are a DevOps engineer working with GC.
Conclusion
The adoption of Google Cloud is growing and with it the demand for experienced GC professionals. The role of DevOps Engineer has also been in high demand, with great salary growth prospects given the difficulty companies are facing in finding such competency. This all makes the GC Professional Cloud DevOps Engineer certification a very attractive one, especially considering the relatively low barrier to getting certified, with a single exam and no prerequisite. For professionals experienced with Google Cloud and skilled in building software delivery pipelines, deploying and monitoring services, and site reliability engineering practices, this could be a great certification to obtain and showcase your knowledge.
Finally, if you decide to take the exam, here are some tips for passing it:
- Take the Performing Foundational Tasks in Google Cloud Platform skill assessment to find out what your current skill level is with GC.
- Also take the Understanding DevOps skill assessment to see where you are in your understanding of DevOps in general. Once you identify your knowledge gaps, create a study plan that focuses on your weak areas.
- Take the time to understand Google's approach to DevOps, which is known as Site Reliability Engineering (SRE). Although the principles are largely the same, SRE is a particular implementation of DevOps and there are certain concepts that are important to understand for the exam.
- If you've never taken a GC exam before, the official practice exam is a great way to get familiar with the exam format. Also make sure you practice time management, as you will have two hours for completing the exam.
