Project Description: DevOps Exercises
What is the project about?
This repository is a comprehensive collection of questions and exercises covering a wide range of technical topics, with a focus on DevOps and Site Reliability Engineering (SRE) concepts. It's designed as a study resource, not a perfect representation of real-world interview questions.
What problem does it solve?
It helps individuals prepare for technical interviews and expand their knowledge in various areas relevant to DevOps and SRE roles. It provides a structured way to learn and test understanding of core concepts and technologies. It explicitly states that it's not a replacement for real-world experience, but a learning aid.
What are the features of the project?
- Extensive Question Bank: Contains over 2600 exercises and questions.
- Broad Topic Coverage: Includes topics like DevOps, Git, Network, Hardware, Kubernetes, Software Development, various programming languages (Python, Go, Perl), Cloud platforms (AWS, Azure, GCP), Operating Systems (Linux), Databases (SQL, Mongo), CI/CD, Containers, Observability tools (Prometheus, Grafana), Security, System Design, and more.
- Organized Structure: Content is organized into topic-specific directories, making it easy to find relevant material.
- Contribution-Friendly: Encourages community contributions through pull requests.
- Links to Mobile Apps: Provides links to related mobile applications (KubePrep, Linux Master) for on-the-go learning.
- FAQ and Contribution Guidelines: Includes a FAQ page to address common questions and contribution guidelines to maintain quality.
What are the technologies used in the project?
The project itself is primarily a collection of Markdown files, so the "technologies" are the topics covered, which include (but are not limited to):
- Operating Systems: Linux, General OS Concepts
- Networking: TCP/IP, OSI Model, DNS, DHCP, NAT, Load Balancing, SSL/TLS
- Cloud Platforms: AWS, Azure, GCP, OpenStack
- Containerization: Kubernetes, Docker, OpenShift, Argo
- Databases: SQL, MongoDB, Cassandra, ElasticSearch
- Programming Languages: Python, Go, Perl, Shell Scripting
- Configuration Management: Ansible, Terraform, Puppet
- CI/CD: CircleCI, Jenkins, general CI/CD principles
- Monitoring & Observability: Prometheus, Grafana, DataDog
- Version Control: Git
- Security: General security concepts
- System Design: Scalability, High Availability, Distributed Systems
- Big Data: Hadoop, Data Lakes, Data Warehouses
- Other: Chaos Engineering, Kafka, NodeJs
What are the benefits of the project?
- Improved Interview Preparation: Helps candidates practice and solidify their understanding of key concepts.
- Knowledge Expansion: Provides a structured way to learn about a wide range of technologies.
- Community-Driven Learning: Benefits from contributions and updates from the community.
- Free and Open Source: Accessible to anyone without cost.
- Self-Assessment: Allows individuals to identify areas where they need further study.
What are the use cases of the project?
- Preparing for DevOps/SRE interviews.
- Learning new technologies and concepts.
- Refreshing existing knowledge.
- Self-assessment of technical skills.
- Supplementing formal education or training.
- Onboarding new team members (with the caveat that it's not a complete training program).
