A Guide on How to Become a DevSecOps Engineer?

by prince kDevOps Practice and Process

Who is DevSecOps

The term DevSecOps is a collaborative working method that implements security over development and operations teams. This collaboration aims to reduce the risks, into all stages of DevOps projects.

DevSecOps believes that security should be everyone’s priority whoever is working on the project. It will help to prevent the risks which will enhance the experience of customers when they will use the product after deployed in the market.

In other words, DevSecOps engineers ensure that the organization’s network and IT infrastructure remain free from security flaws.

DevSecOps keep their eye on all stages whether it is development, testing, monitoring, etc for security purposes.

The DevSecOps engineers must be aware of specific toolsets like Docker, Jenkins, Java, Python, Perl, Ruby, Scripting YAML, DAST (Dynamic Application Security Testing), SAST (Static Application Security Testing).

What does a DevSecOps engineer do?

  • Process monitoring
  • Writing risk analyzes
  • Incident management
  • Testing, selection, and implementation of technologies, tools, and working methods
  • Automation of security controls
  • The maintenance of the system and the external and internal computer network of the company
  • Control and management of security operations
  • More broadly, they participate in the construction of a “safety culture” within the company by supporting the various teams and customers in the implementation of good safety practices.
  • Provide packaging/deployment capability to deliver products to point of need, including multiple cloud-based solutions.
  • Support multiple agile teams across various platforms, environments, and instances
  • Incorporate best practices to increase the quality & velocity of deployments
  • Implement security best practices and configuration management
  • Increase system performance with a focus on high availability and scalability

How to Become a DevSecOps Engineer?

To be a DevSecOps engineer requires a set of skills and practical experience. DevSecOps engineers should aware of how security impacts each stage of the development pipeline and the finished product or service.

Of course, soft skills also matter to build better communication between team members to work effectively with each other.

The work of a DevSecOps Engineer is like many other IT security professional roles but it is a little dia different in terms of DevOps.

Both IT security professionals and DevSecOps engineers use distinctive best practice tools and methods like cybersecurity software, threat modeling, and risk assessments to recognize and analyze threats.

As a role of DevSecOps in projects, security isn’t an afterthought but is placed into the software at the time of the development, by using secure coding.

During development, the software is attacked to find vulnerabilities, because it is opposed to running a scan once it is created.

Automation tools play a key role to detect vulnerabilities, so DevSecOps should aware of such toolsets.

Some skills that are required:-

  • Should have knowledge of the DevOps culture and principles.
  • An understanding of programming languages such as Docker, Jenkins, Perl, Java, Python, and PHP would be helpful.
  • Strong teamwork and Soft skills (communication skills).
  • Should have knowledge of threat modeling and risk evaluation techniques.
  • Up-to-date knowledge of cyber security threats, current best practices, and the latest software.

These skills can be obtained by either having trained through any institute that provides training or course or directly from organizational training during job roles.

Qualification and knowledge

  • Should have experience and knowledge of programming languages and automation tools.
  • People should have technical degrees such as engineering or computer science.
  • Getting certifications from a well-known platform will help you to get into this role even without having a technical degree. 
  • Experience with common DevOps related tools, such as:-
  • Jira
  • Confluence
  • Jenkins
  • Artifactory
  • GitHub
  • Docker
  • Kubernetes
  • Ansible
  • Terraform
  • Should have experience with programming and scripting languages, such as C/C++, C#, Python, JavaScript, PowerShell, Bash, etc.
  • Should have experience with virtualization technologies on-premise or cloud-based services such as  Microsoft Azure, AWS VMs, VMware vCenter/ESXi,  and Hyper-V.

Is an SRE Career Right for You? Things to Consider Before Making the Decision?

by prince kUncategorized

Yes, SRE is the right career for me. SRE will be in the market for a longer period because SRE provides the solution of reliability, stability, and incremental improvements which will keep it in demand for a longer period.

That’s why SRE is a better choice for the long term and as a career. According to research, 33 percent of IT execs stated SRE/DevOps is the most crucial skill for organizations.

That same study found that 87 percent of those leaders say finding these professionals is very difficult. It also tells the demand in the market.

As SRE has removed the ‘Silos’, you can have fun working with other departments which can expand your knowledge as well.

And there are several reasons to consider it better Career purpose to be an SRE –

Higher salary: SRE engineers are getting good salaries than other engineers. if you like to earn, this might be a primary motivation or reason for following the SRE career path rather than a DevOps path.

You don’t need to be a technical expert to work in the SRE team. Basic knowledge will also work And the rest of the knowledge you can get from training under the SRE team. So more benefit in less thing can be considered much better than other.

More prestige: As it has been originated by Google it can be considered as one of the more prestigious jobs in the whole world.

SRE works in the collaboration with other departments, and SRE’s job is to maintain the reliability of the product, (which means less problem and efficient product) so it makes the working team images good in front of others on its own. So just because of the work, it makes the profile more prestigious.

Automation Mastery: With automation tools, SRE can scale easily and perform faster and more efficiently to remove the manual work as much as possible.

They can apply automation on repetitive tasks so they can focus most of their time on doing more high-value work and improving the product. Experience with automation tools is a priority and important for SRE candidates.

Site Reliability Engineers Are a Hybrid of Technical and Soft Skills: The skillsets of SRE are a mix of both technical and soft skills. Technical skill is necessary, but communication and collaboration are also important and it of course comes under soft skills because you can’t misbehave with anyone. The best SREs can do comfortably both things.

Things to Consider Before Making the Decision?

⦁ Rising Demand for SRE Talent – As it has been seen companies are realizing that reliability comes first is key to success somewhere. Downtime costs, customer expectations, and consistency.

That means a massive SRE craze is coming very soon. LinkedIn ranked SRE in the Fifth position in its 2020 United States Emerging Jobs Report, and it showed 34% annual growth.

AS digital market is increasing complexity are also showing their faces, so companies are hiring a dedicated team to solve the reliability concerns. That means as SRE is showing growth, it’s gonna dominate the 2021 jobs portals. In other words, there will be a rise in the demand for SRE talent.

According to, Maya Ber Lerner of DevOps.com states, “Increasing levels of automation will require smart ways to handle dynamic infrastructure and applications without losing control, and being able to track changes back to the coder.”

This will demand SRE best practices around observability, error budgets, and documented and automated incident management capabilities.

So This can be the reason for the increase in demand for SRE.

⦁ SRE Offers a Definite Career Path that Promises Steady Growth – Yes, SRE Offers a definite Career Path that Promises Steady growth, because SRE Plays a vital role in the Digital world by their monitoring and automation, especially to those who wants to run their operations efficiently so their products can perform effectively in customers hand.

And of course, it can be done perfectly through only SRE because it focuses on only operations works to solve the problems to run the product effectively in the market.

So just because of the nature of SRE, it will be in the market for a longer period and as long as SRE be in the Market, it needs engineers. So directly indirectly SRE provides good growth as per your skills.

SRE is the core of a successful business and most companies find they have a role pretty similar to SRE today in the world of software in the world of technology.

⦁ Your Key Responsibility Areas (KRA) as SRE Expert – SRE understands that failure will happen. Failure is just the nature of business. You can’t design the perfect system.

So SRE programmatically identifies potential failures and solves them ahead of time, and it is also good at identifying how are we going to solve immediate tactical problems.

So as an SRE expert you are responsible to monitor the product when it will be running in the market, fixing the issues, bugs, blot wares, etc with automation to eliminate the manual work on the same issue again n again.

SRE also gets the feedback and the actual real-time data of software functioning, and it gives it back to the developer team, so they can make reliable software and remove the vulnerabilities.

Monitoring and logging are just keys to SRE roles. So SRE’s in monitoring terms, they are keeping track of what’s happening in real-time. Logging is an archive of what has happened, so you can go back to examine it later.

So your monitoring going to give you the ability to anticipate failures and see them coming, so you can proactively solve them.

Logging is when you get an unanticipated failure, it allows you to get back and see what happened. You can do RCA ( Root cause analysis ) on it, and figure out how to solve it, not just for now but for the future.

⦁ Technical Skills Needed to Build an SRE Career – Some required skills are:-

They should know “How to Code”

They should have “In-depth knowledge of version control”

They should have “good knowledge of operating Systems”

Acquire knowledge of “Cloud-native applications”

Build a good understanding of “Distributed computing”

Acquire the “CI/CD implementation expertise”

Build an in-depth understanding of “monitoring tools”

Build “troubleshooting skills”

Build “Communication & Collaboration” skills

To learn all these skills you have to learn various tool-sets. I am going to mention those below which are used by various organizations currently.

S.no Problems Tools

1 Operating Systems – Centos/Ubuntu & VirtualBox & Vagrant
2 Cloud – AWS
3 Containers – Docker & Kubernetes – Helm
4 Planning and Designing – Jira & Confluence

What are Agile and DevOps?

by prince kDevOps Practice and Process

Agile – Agile refers to software development methodologies based on iterative development, where requirements and solutions evolve through collaboration between self-organizing cross-functional teams. It is a process that promotes disciplined project management that encourages inspection and adaptation, self-organization and accountability, rapid delivery of high-quality software, and aligns the development of software with customer needs and company goals.

DevOps – DevOps is originated from Dev and Ops word which is development and operation. It has come out as a cultural philosophy and practice change which makes the collaboration between Development and operation team to fasten the software development and delivery. DevOps is originated from Dev and Ops word which is development and operation. It has come out as a cultural philosophy and practice change which makes the integration between Development and operation team fasten the software development and delivery. At the time of development of software its has always been seen that security is always a major concern, so for this DevSecOps came between that look after the security concern from the development process. It ensures the finished application is secured at all aspects of running the application.

What are some common misconceptions about Agile and DevOps?

DevOps & Agile Implementation - Landmark System & Solutions Pvt.Ltd

Agile and DevOps both are meant to help in functioning smoothly and efficiently the development and release process. But still, some people have spread the rumor which harming the DevOps and Agile image. So for today, we going to discuss some of the myths/ Misconceptions. Let’s start.

DevOps Misconceptions:-

DevOps Requires Agile – DevOps doesn’t require agile methodology, it’s a whole process on its own. DevOps and agile both have different ways to work and to develop software. DevOps is a process that integrates the development and operations team to enable continuous development and delivery of software whereas Agile emphasizes the iteration of development and testing in the SDLC process (which means it breaks down the product into smaller pieces and integrates them for final testing to build a ready to use application).

You Can’t have DevOps without Cloud – Basically, it’s not true. There are ways to use DevOps separately as DevOps is a philosophy rather than a technology, it can scale and adapt to change much better in comparison to cloud computing. But still with this advantage, without the ability to set up and provision new machines programmatically and without the cloud’s API, DevOps functioning feels limited because the cloud provides the ability to flexibly manage the computing resources we need, So cloud is important for DevOps functioning efficiently.

DevOps Doesn’t Work for Large, Complex Systems – It is not like this. Earlier It was said, that the waterfall model is best for large and complex systems, but it’s not true. DevOps has been led just to remove all vulnerabilities which all the older models had in the development process to function well whether it is for a large or complex system. It happening because DevOps using modern methods to make the tasks easy and day by day things are improving. So the conclusion is DevOps fits over all types of systems.

It is Exclusive to Native Internet Companies – DevOps is an approach that is widely used by the whole world. So DevOps can’t be limited to any extent which means it is inclusive to native internet companies.

DevOps Requires Teams’ Physical Proximity – It’s a baseless myth I have ever heard. DevOps never require any kind of physical proximity. DevOps can work without physical appearance. With the help of the latest techniques like remote workers, third-party contractors, and cloud service providers, DevOps can perform much better than anyone as well as With the right tools and frameworks to support communication and collaboration in the DevOps lifecycle could give an effective result.

DevOps is Only for Continuous Delivery – It would be wrong if it is said like this. DevOps is not only for continuous delivery it is for continuing operations as well. the duty of its to ensure the continuous development, delivery as well as deployment to the market so the organization can achieve the required goal. Even though After deployment DevOps teams monitor the performance as well to push the updates. So the DevOps works are much more than only continuous delivery of software.

Soft Skills Aren’t Necessary – Soft skills needs everywhere whether it is in DevOps or not. Dev and op team is bound to work with each other so it’s important to be polite with each other in terms of working efficiently. Sometimes some organizations provide such soft skill training as well to be one of the well-disciplined organizations.

Agile Misconceptions:-

Agile models cannot work with other models – It’s not true, Instead, Agile methodology offers more flexibility to their users to include various aspects of traditional methods into it. The stages of product development cycles of the agile method are shorter and multiple, and they are complete like other traditional methods. In such a manner, agile methods are compatible with the processes of traditional methods. The only way to combine the agile method with a traditional plan-driven model like the waterfall model, waterfall uses the sprints of the agile method within the linear structure to start work for the next stage without completing the work of the previous stage.

No planning is required for the projects – The development process of agile is neither plan-driven nor has Gantt charts or WBS but still its plan at the number of points like Dev Sprint Planning of formalized ceremonies comprising PO and PBR to address the goals and priorities of the project of the team. The ceremony is related to the owner of the product communicating the details to the project team about their requirements and the project manager and the team establishing their priorities to complete the task as planned, to build and run the project successfully.

Role of management is eliminated in agile methodology – The is also one of the myths because the role of every person is defined in agile as well as the owner of the product involved as the manager of the project. The supervision of the project ( the goals and priorities of the project team and leading the team to accomplish the task ) is the responsibility of the product owner.
In agile projects the product owner, along with a Scrum Master who is responsible to ensure the development teams of the project complete the tasks within each sprint by working in the best condition.

Agile is specifically for Software Development – Initially agile started with the development of software but later it emerged as a complete methodology, which can be used in distinctive projects where the ability of change and continuation is higher and feedback cycles are shorter. So again it’s a myth.

Agile means no need for software testing – In Agile, test cycles are planned for every sprint with the user stories that developers intend to address in that sprint. Testing is the central part of the success of an agile development lifecycle and it keeps continuous until the final product meets all requirements.

Agile means DevOps – Both are different from each other. Agile is based on iterative development and DevOps is a cultural change that works with the integration between dev and op teams to continuous development and delivery of software.

Conclusion

In this blog, we have discussed the Definition of Agile and DevOps, and some misconceptions about both of them. As I have mentioned above both are good to each other but in a current scenario, DevOps is much better than anything. but still, all are good at their place and Agile is also one of them and I have tried to remove some of the misconceptions above. Hope so it will be helpful to you guys.

What are DevOps, DevSecOps, and SRE, and differences among them?

by prince kUncategorized

DevOps – DevOps is the combination of culture, practices, and tools that increase an organization’s ability to deliver applications and services at high quality, as well as automate and integrate the processes between development and IT teams.


DevOps teams use tools to automate the process, which helps to increase reliability and efficiency.
DevOps ensures fast software delivery with minimum problems to fix and faster solution to problems.
The term DevOps has been made up of two words development and operations.


DevOps is a process that permits the Developer and operation teams to collaborate with each other to manage the whole application development life cycle, i.e. development, testing, deployment, monitoring, etc. DevOps aims to shorten the period and cost of development of the application.

DevSecOps – DevSecOps is a useful umbrella term that collects the processes introduced by organizations who want to run their operations on AWS, Azure, and Google cloud.


DevSecOps is about not only making software easily installable but making the process of installing it more secure and usable.

DevSecOps is not only making the software installation easy, but it makes the installation process more secure and usable as well.


Prior, the development cycles lasted for months or even years, and the release of new versions or software updates of their applications used to be released just once or twice a year.
It gave enough time for quality assurance and security testing teams to carry out security measures which is make the process very slow.


But these outdated security practices or separate security teams cannot keep up with the speeds of DevOps initiatives.
This vulnerability leads to the evolution of the DevSecOps methodology, where the development, operation, and security team, work together and share end-to-end responsibilities in the entire development life cycle to finish the project in less time.


DevSecOps methodology automates the integration of security at every stage of the software development lifecycle, from the initial design.


DevSecOps integrates the security of application and infrastructure seamlessly in Agile and DevOps processes and tools.

SRE – SRE stands for site reliability engineering.


In around 2000 Google realize DevOps is good as it is but there is something else that can be done. So there were a lot of different ideas flowing around then Google come up with this idea called an SRE.


It is a software engineering approach to operations where an SRE team uses software as a tool to manage systems and solve problems and automate operational tasks.


So basically, SRE takes the tasks which have been done often manually by the operation teams and instead of giving them to engineers or Operations teams who use software or automation to solve these problems, they do it themselves and manage the production environment.


In other words, SRE teams are made up of software engineers who build and implement software to improve the reliability of their systems.


SRE teams are responsible for how code is deployed, configured, and monitored as well as checks for the availability, latency, change management, emergency response as well as capacity management of service in production.


So how SRE does all these things, Basically it helps to determine the new features that are being launched, they test it across a few different metrics, so they check it across these things called SLA (Service Level Agreement), SLI (Service level indicator), and SLO (service level objectives).

Differences between DevOps, DevSecOps, and SRE

DevOps, DevSecOps, and SRE all work to bridge the gap between development and operation teams to deliver faster and reliable services.

DevOps and DevSecOps


DevOps is the process of integrating development and operations and focuses on eliminating the communication gap between different teams so that the whole code development and deployment process is done faster whereas DevSecOps solves the security concerns along with deployment.


DevOps is only responsible for Development and operational tasks related to a single project but DevSecOps suggests that security is everyone’s responsibility.


DevOps team requires the skillset of Linux fundamentals and scripting knowledge of various tools and technologies whereas DevSecOps engineers should be skilled with addressing the vulnerabilities with automated security tools. Need to have knowledge in cloud security and provide support to infrastructure users.


DevOps has some benefits like speed, rapid delivery, reliability, scale, improved collaborations, security whereas DevSecOps has improved agility, considers security automation, keeps security as code.


Automation is done for security testing so the development is tested on regular basis.

The report generates if any vulnerabilities are found during CI and CD. DevSecOps never allow security to get compromised. whereas automation in DevOps is for releasing codes in a higher environment. This helps developers to know about the changes has done by the members and to work accordingly.


Monitoring the security incident is done through incident management. Proper standards are created to raise Thus security concerns are managed in DevSecOps. In DevOps, Application infrastructure is managed through codes as infrastructure as codes. Here designing and managing the code is happen on the same platform.

DevOps And SRE


DevOps reduce silos whereas SRE doesn’t concern about the silos. DevOps involve unexpected failures, whereas SREs focus on no failure happening at all.


The automated workflow needs constant monitoring, in this process DevOps team ensures software is working effectively whereas SRE believes that operations are a software issue.


SRE practice involves a contribution from each level of the organization whereas DevOps is all about development and operations only.


SRE uses developers and tools to solve IT operation problems and workflow problems. Thus, SRE does most things through software engineers whereas DevOps uses a development and operation team to finish the work from building to deploying the software in the market.


SRE doesn’t have any special script to follow, but it offers a hard prescription to solve the problems and which tools to use. Whereas DevOps has a development lifecycle that describes what to do.

All these courses are being done at one of the best platforms which are DevOpsschool. If anyone is looking for an institute where you can learn DevOps, you should go for this.
