Penetration Testing and Vulnerability Assessment: Experience in using tools to test the security posture of cloud systems and mitigate vulnerabilities.

DevOps and Automation

CI/CD Pipelines: Experience in setting up and managing continuous integration and continuous deployment pipelines using tools like Jenkins, GitLab CI, AWS CodePipeline, Azure DevOps, etc.

Infrastructure as Code (IaC): Proficiency in tools like Terraform, AWS CloudFormation, Azure Resource Manager (ARM), or Google Cloud Deployment Manager for automating cloud infrastructure provisioning.

Configuration Management: Familiarity with tools such as Ansible, Chef, Puppet, or SaltStack for managing and automating cloud configurations.

Containerization and Orchestration: Expertise in working with containers (e.g., Docker) and orchestrating them using Kubernetes, Amazon ECS, Google Kubernetes Engine (GKE), or Azure Kubernetes Service (AKS).

Networking & Connectivity

Cloud Networking Concepts: Knowledge of cloud networking principles including VPC, subnetting, load balancing, DNS, NAT, and security groups.

Virtual Private Networks (VPNs) & Direct Connect: Designing secure communication between cloud and on-premises networks.

Global Distribution & CDN: Familiarity with Content Delivery Networks (CDNs), edge services, and multi-region cloud deployments for globally distributed applications.

SD-WAN & Hybrid Connectivity: Understanding of hybrid cloud networking solutions that connect on-premises data centers with cloud infrastructure.

API Gateway & Service Mesh: Using tools like AWS API Gateway, Azure API Management, Istio, or Linkerd to manage API traffic and service-to-service communication in microservices architectures.

Cloud Cost Management and Billing

Cost Optimization Strategies: Identifying underutilized resources and recommending optimizations to minimize costs.

Pricing Models and TCO (Total Cost of Ownership): Understanding of different cloud pricing models (on-demand, reserved instances, spot instances, etc.) and the ability to estimate and manage costs using native tools like AWS Cost Explorer, Azure Cost Management, and Google Cloud Pricing Calculator.

Budgeting & Forecasting: Experience in setting budgets, forecasting costs, and managing billing alerts to avoid unexpected charges.

Programming & Scripting

Programming Languages: Proficiency in at least one or more programming languages such as Python, Java, Go, or JavaScript for automation and tool development.

Scripting Languages: Experience with shell scripting, PowerShell, or Bash for cloud automation tasks.

Cloud SDKs and APIs: Familiarity with the software development kits (SDKs) and REST APIs provided by cloud vendors to interact with cloud services programmatically.

Data Management and Analytics

Big Data Solutions: Experience with cloud-based big data processing tools such as AWS Redshift, Google BigQuery, or Azure Synapse Analytics.

Data Lakes and ETL: Knowledge of creating data lakes and handling ETL (Extract, Transform, Load) processes in the cloud.

Machine Learning Integration: Familiarity with integrating machine learning services like AWS SageMaker, Azure ML, or Google AI Platform into cloud solutions.

Real-Time Data Processing: Experience with real-time data processing tools like AWS Kinesis, Google Cloud Pub/Sub, or Azure Event Hubs.

Monitoring Logging and Troubleshooting

Monitoring & Alerting: Knowledge of cloud-native monitoring tools like AWS CloudWatch, Azure Monitor, or Google Operations Suite (formerly Stackdriver).

Logging Services: Proficiency in centralized logging solutions like AWS CloudTrail, Azure Log Analytics, or Google Cloud Logging.

Troubleshooting Tools: Experience with cloud diagnostic tools to troubleshoot performance issues, latency, and failures in cloud-based applications.

Soft Skills

Leadership & Collaboration: Strong ability to collaborate with cross-functional teams including development, operations, and business units and provide technical leadership in designing cloud solutions.

Communication Skills: Ability to clearly communicate technical concepts and cloud strategies to non-technical stakeholders and executives.

Project Management: Ability to manage and drive cloud-related projects from inception through to completion ensuring they are delivered on time and within scope.

Problem-Solving: Strong troubleshooting and analytical skills to diagnose and resolve complex cloud-related issues.
