RedHat OpenStack Telco Cloud Architect

As a RedHat OpenStack Telco Cloud Architect, your key responsibilities include designing and deploying Network Function Virtualizations (NFV) and Software Defined Networking (SDN) within a Telco Cloud context. You will manage the integration of the Red Hat OpenStack Platform and ensure seamless operations of network and storage configurations using the latest OpenStack versions. Engaging in troubleshooting, patch management, and hardware maintenance are also part of the role, alongside communicating effectively with stakeholders to meet project goals.

To qualify as a RedHat OpenStack Telco Cloud Architect, you should possess 12-15 years of experience in Linux/Unix systems, with a minimum of 3 years in the Telco domain. Proficiency in Red Hat OpenStack, Ceph storage, and NFV/SDN technologies is critical. Additional skills in scripting with Python and automation using Ansible, along with a good understanding of Kubernetes and virtual networking, will further enhance your profile.

Experience with RedHat Ceph storage is essential for a RedHat OpenStack Telco Cloud Architect, as it plays a crucial role in data storage and management within the OpenStack infrastructure. You'll need hands-on experience with Ceph deployment best practices and integration with Red Hat OpenStack Platform to ensure efficient storage solutions for large-scale telecom operations.

A RedHat OpenStack Telco Cloud Architect should be familiar with several key tools and technologies including OpenStack Networking (Neutron), SDN/NFV MANO architecture, Kubernetes, OpenShift, Docker, and various versions of the Red Hat OpenStack Platform. Additionally, knowledge of automation tools like Ansible and experience with hypervisors and Cisco-based technologies is highly valuable in this role.

Soft skills are just as important as technical expertise for a RedHat OpenStack Telco Cloud Architect. Strong communication and presentation skills are essential to convey complex technical information to diverse audiences. You'll also need effective problem-solving abilities and adaptability to navigate the evolving landscape of telecom and cloud technologies.

In answering this question, highlight your specific experiences with different versions of Red Hat OpenStack, describe projects you've worked on, and discuss your role in deploying and managing OpenStack solutions, particularly emphasizing any complex scenarios you handled.

When discussing NFV and SDN, explain that NFV focuses on virtualizing network services that traditionally run on hardware, while SDN concerns the separation of the data plane from the control plane, allowing for more centralized network management. Give examples of how you've implemented or managed these concepts in real-world projects.

To ensure high availability in a cloud environment, discuss the strategies you use, such as implementing load balancers, creating redundant systems, and using failover techniques. Provide examples from previous projects where you successfully maintained uptime.

Share a specific scenario where you encountered a significant issue, outline the steps you took to diagnose and resolve it, and reflect on what you learned from the experience. This will demonstrate your problem-solving skills.

Explain how automation tools like Ansible or Puppet streamline deployment processes, reduce human error, and enhance operational efficiency. Provide examples of how you’ve successfully integrated automation in your previous roles.

Discuss your hands-on experience with Ceph storage, including how you have integrated it with OpenStack and managed performance optimization. Mention specific projects where you dealt with storage challenges and your approach to solving them.

When addressing this question, describe the steps you would take to assess resource needs, plan for scaling, and execute the scaling process while ensuring minimal disruption to existing services. Mention tools or scripts you have used in this process.

Discuss your understanding of cloud security best practices, such as implementing firewalls, VPN, encryption, and regular security audits. Share experiences where you successfully implemented security measures to protect cloud environments.

Highlight the scripting languages you are proficient in, especially Python for automation and deployment tasks. Discuss specific instances where your scripting skills enhanced your operational effectiveness in OpenStack environments.

Share your strategies for staying updated, such as subscribing to industry publications, participating in online forums, attending webinars/conferences, or engaging in continuous education. Emphasize the importance of keeping your skills current in a rapidly evolving field.
