Cloud computing and DevOps
The growing adoption of cloud technologies goes hand in hand with the growing demand for certified professionals. Cloud certifications are considered a reliable way to assess an individual's technical skills and knowledge in deploying, managing, and securing cloud services and applications.
Three players, Microsoft Azure, Amazon Web Services (AWS) and Google Cloud Platform (GCP) share theessential of the market. Obtaining one of the official certifications issued by one of these cloud service providers (CSPs) allows you to prove your skills in areas such as architecture, administration or development.
Each CSP offers certifications giving access to specific services. But it is recommended that cloud professionals know all the players in the market well, because companies rarely choose a single supplier. They can combine several to meet their needs.
Finally, a cloud certification is not only beneficial for cloud engineers and architects. Professionals in the fields of business intelligence, data science, and even big data can increase their value by acquiring skills in cloud computing.
Here are some of the most recognized CSP cloud certifications:
