But before delving into the blog, let’s first know what a cloud engineer is.

What is Cloud Engineering?

Cloud engineering encircles the creation, handling, and supporting resources of computer infrastructure. With growing technology, the importance of Cloud engineering is attaining momentum. Cloud technology has allowed you to watch your favorite shows online and listen to songs with complete access. It utilizes engineering principles to create systems, and everybody wants to know how to be a cloud engineer

Cloud engineers decrypt the computing problems of an entity or consumers. The services provided are software as a service (SaaS), platform as a service (PaaS), and infrastructure as a service (IaaS). As a cloud engineer, you will be in charge of storing, handling data, and moving with timely software updates. In totality, you will oversee the cloud system operating smoothly without any obstacles.

Reliability: Cloud service providers ensure high availability and data redundancy to minimize downtime.

Security: Cloud providers implement advanced security measures to protect data and prevent unauthorized access.

  1. How would you explain the difference between a public cloud and a private cloud?

A public cloud is a platform that is accessible to multiple organizations or individuals over the Internet. It is managed and maintained by a third-party service provider. On the other hand, a private cloud is dedicated to a single organization and is either physically located on-premises or hosted by a third-party provider. Private clouds offer greater control and security but may involve higher costs.

Scalability refers to the ability to increase or decrease resources based on demand. Elasticity specifically focuses on the automatic scaling of resources in real-time as demand fluctuates.

  1. What is a virtual machine in cloud computing?

 A virtual machine (VM) is a software emulation of a physical computer. It allows multiple operating systems to run on a single physical machine.

  1. What is a container in cloud computing?

 A container is a lightweight, portable unit that packages an application and its dependencies together. It ensures consistency and reliability when deploying software across different environments.

  1. What is AWS, and what are some of its core services?

AWS (Amazon Web Services) is a comprehensive cloud computing platform provided by Amazon. Core services include EC2 (Elastic Compute Cloud), S3 (Simple Storage Service), RDS (Relational Database Service), and more.

  1. Explain the difference between Amazon S3 and Amazon EBS.

Amazon S3 is an object storage service used for storing and retrieving data, while Amazon EBS provides block-level storage volumes that can be attached

  1. What is Google Cloud Platform (GCP), and what are its core offerings?

GCP is a suite of cloud computing services offered by Google. Core offerings include Compute Engine, App Engine, Cloud SQL, and Cloud Storage.

  1. How do you ensure data security in a cloud environment?

Data security in a cloud environment can be ensured through encryption, access control measures, regular security audits, and compliance with industry standards.

  1. What is IAM in AWS?

IAM (Identity and Access Management) is a service that allows you to manage users, groups, and roles in AWS, controlling their permissions to access AWS services and resources.

  1. What is a Virtual Private Cloud (VPC)?

A VPC is a virtual network dedicated to an AWS account. It allows resources to be launched into a virtual network, providing isolation and control over network configuration.

  1. Explain the concept of Load Balancing in the cloud.

Load Balancing evenly distributes incoming network traffic across multiple servers to ensure no single server is overwhelmed, improving the availability and reliability of applications.
