What is Cloud Engineering?

Cloud engineering refers to the practice of designing, building, and maintaining cloud computing systems and infrastructure. 

Cloud engineers are responsible for creating and managing the architecture that enables businesses to store, process, and analyze data, as well as run applications over the internet instead of on physical hardware. 

They work with a variety of cloud computing services, such as infrastructure as a service (IaaS), platform as a service (PaaS), and software as a service (SaaS), to develop scalable, secure, and reliable solutions that meet the needs of their organization or clients. 

Cloud engineering involves skills in areas such as virtualization, networking, security, automation, and programming, as well as a deep understanding of cloud platforms like Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform.

Importance of Programming Languages in Cloud Engineers

Programming languages play a crucial role in cloud engineering for several reasons:
