Cloud Service Providers: In-depth knowledge of one or more cloud platforms like AWS, Azure, or Google Cloud.
Networking: Understanding cloud networking concepts such as VPC, subnets, routing tables, and security groups, as well as configuring VPNs, DNS, and load balancers.
Security: Expertise in IAM, multi-factor authentication (MFA), encryption, security groups, and access control policies.
Scripting and Automation: Familiarity with scripting languages like Python, Bash, or PowerShell, along with tools like Terraform for infrastructure as code (IaC).

Soft Skills

Problem Solving: A Cloud Support Engineer must possess strong problem-solving abilities, able to troubleshoot and fix technical issues quickly and efficiently.
Communication: Clear and effective communication skills are crucial, especially when interacting with customers, explaining technical issues to non-technical users, and creating documentation.
Customer Support: Being patient, empathetic, and solution-oriented when dealing with clients facing challenges with cloud infrastructure.
Collaboration: Working with other technical teams to resolve issues and ensure optimal cloud environments.

3. Key Cloud Platforms and Services

Amazon Web Services (AWS)

AWS is one of the most popular cloud platforms, offering a wide range of services such as EC2, S3, RDS, Lambda, and VPC. For a Cloud Support Engineer role, you must be familiar with these services and how to troubleshoot issues related to them.

Microsoft Azure

Azure provides a wide variety of services similar to AWS, such as Virtual Machines (VMs), Blob Storage, Azure Functions, and Azure Active Directory. Familiarity with these services is essential for a Cloud Support Engineer working with Azure environments.
