What do you know about DevOps?
Your answer must be simple and straightforward. Begin by explaining the growing importance of DevOps in the IT industry. Discuss how such an approach aims to synergize the efforts of the development and operations teams to accelerate the delivery of software products, with a minimal failure rate. Include how DevOps is a value-added practice, where development and operations engineers join hands throughout the product or service lifecycle, right from the design stage to the point of deployment.
Which are some of the most popular DevOps tools?
The most popular DevOps Tool include:
1. Selenium
2. Puppet
3. Chef
4. Git
5. Jenkins
6. Ansible
7. Docker
How will you approach a project that needs to implement DevOps?
The following standard approaches can be used to implement DevOps in a specific project:
Stage 1
An assessment of the existing process and implementation for about two to three weeks to identify areas of improvement so that the team can create a road map for the implementation.
Stage 2
Create a proof of concept (PoC). Once it is accepted and approved, the team can start on the actual implementation and roll-out of the project plan.
Stage 3
The project is now ready for implementing DevOps by using version control/integration/testing/deployment/delivery and monitoring followed step by step.
By following the proper steps for version control, integration, testing, deployment, delivery, and monitoring, the project is now ready for DevOps implementation.
What is the role of AWS in DevOps?
AWS has the following role in DevOps:
- Flexible services - Provides ready-to-use, flexible services without the need to install or set up the software.
- Built for scale - You can manage a single instance or scale to thousands using AWS services.
- Automation - AWS lets you automate tasks and processes, giving you more time to innovate
- Secure - Using AWS Identity and Access Management (IAM), you can set user permissions and policies.
- Large partner ecosystem - AWS supports a large ecosystem of partners that integrate with and extend AWS services.
Can you explain the “Shift left to reduce failure” concept in DevOps?
Shift left is a DevOps idea for improving security, performance, and other factors. Let us take an example: if we look at all of the processes in DevOps, we can state that security is tested prior to the deployment step. We can add security in the development phase, which is on the left, by employing the left shift method. [will be depicted in a diagram] We can integrate with all phases, including before development and during testing, not just development. This most likely raises the security level by detecting faults at an early stage.
Mention some of the core benefits of DevOps?
- Faster development of software and quick deliveries.
- DevOps methodology is flexible and adaptable to changes easily.
- Compared to the previous software development models, confusion about the project is decreased due to increased product quality.
- The gap between the development team and operation team is bridged. i.e, the communication between the teams has been increased.
- Efficiency is increased by the addition of automation of continuous integration and continuous deployment.
- Customer satisfaction is enhanced.
List the key components of DevOps.
- Continuous Integration
- Continuous Delivery
- Microservices
- Infrastructure as Code
- Monitoring and Logging
- Communication and Collaboration
How DevOps is helpful to developers?
DevOps is very helpful for developers to fix the bugs and quickly implement the new features. It also helps in more transparent communication between the team members.
