Off topics / Employer Perspectives on DevOps Certifications: What Do They Really Value?

« Last post by wicultyLS on Today at 11:18:49 am »

In today's fast-paced technological landscape, DevOps has emerged as a crucial methodology for enhancing collaboration between development and operations teams, streamlining processes, and accelerating delivery cycles. As organizations increasingly adopt DevOps practices, the demand for professionals skilled in these areas has surged. This has, in turn, led to a proliferation of DevOps certifications aimed at validating these skills. But what do employers really value when it comes to these certifications? At Wiculty Learning Solutions, we’ve delved into this question to provide clarity for both aspiring DevOps professionals and organizations seeking to build robust DevOps teams.

The Role of DevOps Certifications

DevOps certifications serve as formal acknowledgments of a candidate's proficiency in various DevOps tools, practices, and methodologies. They cover a wide range of topics from automation and continuous integration/continuous deployment (CI/CD) to containerization and cloud-native architectures. Popular certifications include those offered by AWS, Microsoft Azure, Google Cloud, Docker, Kubernetes, and various vendor-neutral organizations like the DevOps Institute.

What Employers Really Value

1. Practical Skills Over Theory

   While certifications are a testament to a candidate’s theoretical knowledge, employers place a higher value on practical, hands-on experience. Employers look for evidence that candidates can apply their knowledge in real-world scenarios. This means that hands-on labs, projects, and real-world case studies included in certification programs are highly valued.

2. Relevance to Job Role

   Not all DevOps roles are created equal. Employers prefer certifications that align closely with the specific technologies and practices used within their organizations. For example, a company heavily invested in AWS infrastructure might value AWS Certified DevOps Engineer certification more than a general DevOps certification. Understanding the specific needs of the job role can guide candidates in selecting the most relevant certifications.

3. Proven Problem-Solving Abilities

   DevOps is fundamentally about solving problems to streamline and optimize processes. Employers appreciate certifications that emphasize critical thinking and problem-solving skills. Certifications that include challenging exams or assessments that require practical solutions to complex problems can stand out.

4. Continuous Learning and Adaptability

   The technology landscape is ever-evolving, and so is DevOps. Employers look for candidates who demonstrate a commitment to continuous learning. Certifications that require ongoing education or periodic renewal can indicate a candidate’s dedication to staying current with the latest DevOps trends and tools.

5. Soft Skills and Cultural Fit

   DevOps is as much about culture as it is about tools and processes. Employers value candidates who possess strong communication and collaboration skills, as these are essential for bridging the gap between development and operations teams. Certifications that highlight these soft skills, either through coursework or project work, can be particularly appealing.

How Wiculty Learning Solutions Can Help

At Wiculty Learning Solutions, we understand the nuanced demands of the DevOps job market. Our certification programs are designed to meet these demands, providing a blend of theoretical knowledge and practical skills. Here’s how we ensure our programs align with employer expectations:

Off topics / The Evolution of DevOps Certifications: Trends and Predictions

« Last post by wicultyLS on Today at 11:17:50 am »

The landscape of DevOps has undergone significant transformation since its inception, revolutionizing how organizations develop, deploy, and manage software. As businesses increasingly adopt DevOps practices to enhance efficiency and innovation, the demand for skilled professionals has surged. Consequently, DevOps certifications have become a pivotal component in validating expertise and advancing careers. This article explores the evolution of DevOps certifications, current trends, and future predictions, providing valuable insights for both individuals and organizations.

 The Emergence of DevOps Certifications

DevOps, a blend of "development" and "operations," emphasizes collaboration, automation, and continuous delivery. Initially, the DevOps movement was driven by a community of practitioners sharing best practices. As the methodology gained traction, the need for formalized education and certification became apparent.

Early DevOps certifications were rudimentary, often provided by niche organizations and focusing on basic principles and tools. These certifications aimed to bridge the knowledge gap and establish foundational skills. As the ecosystem expanded, more comprehensive programs emerged, encompassing a wider range of tools, practices, and cultural aspects.

 Current Trends in DevOps Certifications

1. Comprehensive Coverage:
   Modern DevOps certifications offer extensive coverage of the DevOps lifecycle. They include training on continuous integration and continuous delivery (CI/CD), infrastructure as code (IaC), monitoring, security, and agile methodologies. Programs such as AWS Certified DevOps Engineer, Google Cloud Professional DevOps Engineer, and Microsoft Certified: DevOps Engineer Expert provide holistic education, ensuring professionals are well-versed in various aspects of DevOps.

2. Vendor-Specific vs. Vendor-Neutral:
   Certifications are available in both vendor-specific and vendor-neutral formats. Vendor-specific certifications, like those from AWS, Google Cloud, and Microsoft Azure, focus on particular platforms and their ecosystems. In contrast, vendor-neutral certifications, such as the DevOps Institute's DevOps Foundation and DASA DevOps Fundamentals, provide a broader perspective, emphasizing general principles and practices applicable across different environments.

3. Focus on Practical Skills:
   There is a growing emphasis on practical, hands-on skills. Certifications now often include lab exercises, real-world scenarios, and performance-based assessments. This shift ensures that certified professionals can apply their knowledge effectively in real-world settings.

4. Security Integration:
   With the rising importance of cybersecurity, many DevOps certifications incorporate DevSecOps principles. Programs now emphasize secure coding practices, automated security testing, and compliance, reflecting the need for integrating security throughout the DevOps pipeline.

5. Continuous Learning and Micro-Certifications:
   The dynamic nature of DevOps necessitates continuous learning. Micro-certifications and modular training programs have gained popularity, allowing professionals to update their skills incrementally. Platforms like Coursera, Udacity, and Pluralsight offer specialized courses and micro-credentials, enabling learners to stay current with evolving technologies and practices.

 Predictions for the Future of DevOps Certifications

1. AI and Automation Integration:
   As artificial intelligence (AI) and machine learning (ML) become integral to DevOps, future certifications will likely include modules on AI/ML applications in automation, predictive analytics, and intelligent monitoring. Professionals will need to understand how to leverage these technologies to enhance DevOps processes.

2. Expansion of DevSecOps:
   The trend of integrating security into the DevOps lifecycle will continue to grow. Future certifications will place even greater emphasis on DevSecOps, with advanced training on threat modeling, zero-trust architectures, and automated compliance checks.

3. Increased Focus on Soft Skills:
   Collaboration and communication are core tenets of DevOps. Future certifications will likely incorporate training on soft skills, team dynamics, and organizational change management, recognizing the importance of cultural transformation in successful DevOps adoption.

4. Industry-Specific Certifications:
   As DevOps practices become more tailored to specific industries, such as finance, healthcare, and government, certifications will evolve to address industry-specific requirements and regulations. This specialization will ensure that professionals can meet the unique challenges of their respective sectors.

5. Enhanced Learning Technologies:
   Advancements in learning technologies, including virtual reality (VR) and augmented reality (AR), will transform the certification landscape. Immersive learning experiences will provide more engaging and effective training, enabling professionals to simulate real-world scenarios and practice complex skills.

 Conclusion

Directory and Authentication / Re: Sync samba machine account between diffent samba versions - 4.1 to 4.15

« Last post by Gilberto Ferreira on May 21, 2024, 06:25:54 pm »

Hi
It turns out that the DHCP was misconfigured since it sent the wrong DNS server, the gateway one not the main samba server.
After changing it, now everything is working fine.

Thanks.

Directory and Authentication / Sync samba machine account between diffent samba versions - 4.1 to 4.15

« Last post by Gilberto Ferreira on May 17, 2024, 05:44:33 pm »

Hi there.
I have two samba servers, let's say srv01 and srv02. For that matter, both are Zentyal Server 4 and 8, respectively.
In the srv01 there is samba version 4.1, which is in the network 182.168.200.0/24, and which is by the way also the gateway to both network.
In the srv02 there is samba version 4.15, which is in the DMZ network 10.10.100.0/24
The first is an additional controller for the second.
Everything is working fine, except for machine sync.
Let me explain:
- Between these two samba servers, I have a Windows 2022 server. I was able to put Windows 2022 in the samba domain without any problems, which was a bit of surprise to me, since I always used to install SMB1v and SMB2v, first and then add the Windows server into the samba domain.
- I can log in into the Windows 2022 server using the domain account created in the server with samba 4.15
- In fact users created in both samba servers appear on both servers.
- With pdbedit --list I can see the following:
srv01:
pdbedit --list
...
...
SRV01$:4294967295:SRV01$
SRV02$:4294967295:
WINSRV01$:4294967295:
srv02:
pdbedit --list
...
...
SRV01$:3000020:SRV01$
SRV02$:3000022:

As you can see, the windows 2022 server was added in the srv01, which has samba 4.1.17 and does not appear in srv02, which has samba 4.15.13.
Based on that, I wonder if this is something to do with these different versions, before I seek some help with the Zentyal guys.
And I wonder if there is any way to force a sync between the two samba servers, in regard to the samba machines account.

Thanks in advance.

Yes it is in /etc/netplan/netplan.yaml but I think it is also in the mysql db as I tried to add another interface and assign one of the old virt interfaces to it and it says it was a duplicate. Resaving the interfaces does not help either. If you added a gateway manually it also gets stuck.

Installation and Upgrades / Re: Can not install Openvpn, Domain Controller and File Sharing after Upgrading to 8

« Last post by Daniel Joven on May 16, 2024, 12:42:42 pm »

Hi,

What repositories do you have configured? Perhaps you have some Ubuntu repository for previous versions that is causing this issue. Additionally, you can run the following commands to see from what repository is trying to fetch the packages:

Code: [Select]


sudo apt update

sudo apt policy zentyal-samba samba zentyal-openvpn openvpn frr zentyal-ips suricata


Finally, what errors do you get when you try to install those packages?

Best regards, Daniel Joven.

Installation and Upgrades / Re: Error 504 Gateway Time-Out Nginx Zentyal 8 fresh install

« Last post by Daniel Joven on May 16, 2024, 12:34:07 pm »

Hi,

If the webadmin module is running and the server does not have any lock file or load issues, the 504 error might be related to the bug we have fixed and released today in the package zentyal-core 8.0.3, below you have the commit.

- https://github.com/zentyal/zentyal/commit/da6fcd411e3a3acea43d8581eb972f3ba901556d#diff-f2da1cfc0ddd16974080efa028f11a9c2c83db2d36b364d89fabc8f70e797da0

Basically, the webadmin module does a HTTP query to the certain public web page, and if the server that manages that page has load issues, the webadmin module might thrown an error. With this fix, that issue should be solved.

Best regards, Daniel Joven.
