Cloud Engineering- Navigating Career Path as a Beginner.png

With time, the complexity of computational models has significantly increased. Practically, it doesn’t seem convenient to perform all computationally expensive tasks on individual computers. It results in increased dependence and demand for cloud services. This course introduces and navigates through possible career choices in cloud computing.

The course will introduce you to various cloud computing services and different service models. Next, you’ll navigate through different career choices in the field of cloud computing and conclude with the requirements of each career choice. 

By the end of this course, you’ll understand the basics of cloud engineering and the responsibilities of a cloud engineer—planning, designing, monitoring, and managing cloud applications within an organization. This working knowledge will enable you to become a specialized cloud engineer in cloud software engineering and cloud security.

Navigating Cloud Engineering as a Career Path

## Overview
For a long time, the idea of DevOps was flawed. We used to think that DevOps started and ended with continuous integration and continuous delivery (CI/CD). In reality, CI/CD is just one of the many DevOps practices.

> **Note:** DevOps is deeper than a role. It is a culture.

Every internet search or book would explain DevOps as a set of practices that bridge the gap between software developers (Dev) and IT operations staff (Ops).

To appreciate DevOps, we should understand what existed before it.

## Software development methodologies before DevOps

Prior to the introduction of DevOps, most software development teams used the **waterfall methodology**: a sequential model where each software development process depends on the previous phase.
