When an application fails, no one will hear it from their teams-“the problem is not committed by us but evolved from their side.” What is the end result? The client remains unsatisfied that makes users suffers immensely. And the worst part is that no one tries to find out which team is responsible for such heartbreak!
During earlier times, a barrier was always present between developers and operators as they have different goals even if they work to accomplish the same objective. Previously, developers focused on implementing business requirements swiftly to make it seamlessly working product. On the other hand, operators have the sole responsibility to make the product working in all conditions. If anything goes wrong, everyone was put at risk.
So to end such ongoing conflict, DevOps comes into the picture. DevOps solutions have arrived to mend the relationship between the development and operational team and unite them to work towards bringing out the final product in the best quality.
The Evolution of DevOps: How It Was Born?
The father of DevOps is no doubt a Belgian called Patrick Debois. He was the first person to coin the term ‘DevOps’. How does the novel idea come into his mind?
Debois had said in an interview that before the birth of DevOps, there was no insight into things other than running apps. As an admin himself, he could not see logins, access the files after failure, and could not do debugging. These issues were the main driving force for Debois to develop a flexible culture that combines development and operational teams to deliver applications without fail.
Now how the whole procedure gets started?
Patrick had quite an interest in IT and in 2007, decided to work on data migration on a large scale. During that time, he found switching back and forth among the development side is creating a lot of frustration for the operational team.
So, he attended a conference held in Toronto in 2008 about ‘Agile Infrastructure’ from a person named Andrew Shafer. Then in 2009, he watched a streaming video about a topic- “10+ Deploys a Day: Dev and Ops Cooperation at Flickr”. Instantly, he got the solution and initially named it as DevSecOps that soon shortened to DevOps.
Finally, in 2011, Gartner predicted an upward trajectory of DevOps in upcoming years. It is evident from a forecast that the global DevOps market will see a steep rise from US$ 5.3 billion in 2020 to 20.31 billion in 2028 at an 18.3% growth rate. It shows that in the future, DevOps will dominate the IT world not seen ever before.
What is DevOps & How Does it Work?
DevOps (a portmanteau of two terms, development & operation)is a term that combines multiple tools and applications to deliver services swiftly to surge ahead of traditional software solutions. With DevOps in the background, enterprises are delighted to serve their customers in a best-suited way and also have a far reach to the app market.
Simply explaining, DevOps helps the development and operational team to combine their strategy from development to testing and to deployment of the product to offer fruitful results for the customers and business alike.
How DevOps Functions?
Before implementing DevOps, it is essential to know the reason behind the adoption of the newly arrived technology. Don’t just apply for the sake of technology!
What do you need from DevOps? Will it be capable enough to offer you the best quality software apps? Do you want to incorporate to provide faster and cheaper app deliveries to the customers? Or do you want to refurbish your existing IT infrastructure?
So, how DevOps work lies in the hand of enterprises and how they take the journey after getting an answer to the above-given questions.
Therefore, the working of DevOps depends solely on how development and operational teams work in tandem. They don’t become siloed and merge together to form a single team to perform work in the entire application lifecycle from development to testing and deployment and create a product that has multiple functions.
Some DevOps modelscomprise security and quality assurance teams to work successfully throughout the application lifecycle. Even more, many organizations give more priority to security and form a new technology called DevSecOps.
These teams use automation to work on the development lifecycle. Moreover, they also take the help of tooling and technology stack to operate reliably. Besides, DevOps engineers can use these tools to accomplish their tasks to improve their caliber.
What Problems Does DevOps Solve?
These days, marketing demand is changing with each passage of time. It results in the emergence of challenges that affect the working of the IT environment. However, DevOps work with the cloud in tandem to solve any challenges thrown at them.
A. Time to Market
Software development faces a latency-related issue that causes lots of frustration among team members and users. With DevOps at the helm, all the bottlenecks associated with legacy apps reduce significantly via automation. Moreover, it also results in a shortening of time for the product to reach the market.
B. Productivity, Productivity & Productivity
With no DevOps, development teams have to wait behind an operational team resulting in slowing of the entire production procedure. If an enterprise opts for the DevOps philosophy, both the operation and development team can work together to form smooth integration of automation testing to reduce silos to make it a continuous process and thus boost up productivity.
C. App Quality
Traditional methods are too slow that reduces the app quality and make it redundant in the existing market. Nevertheless, DevOps increases inter-departmental communication to produce higher quality and innovative applications with great speed.
No product does magic in the market if it fails to create its own value. But with DevOps, the enterprise can align their business goals with application development to offer real and perceived values to their clients.
DevOps Principles One Must Know
As with any other culture, DevOps also comes with some set of principles. It defines its way of working towards full adoption in the alien environment. Some of the principles are:
Principle 1: Development of Customer-Centric Actions Results in Success
It implies using those products and services that offer maximum satisfaction rates among customers. To show some guts, companies need to be innovative with the inclusion of short feedback cycles.
Principle 2: Create Product Thinking About End Result
It says that instead of using waterfall and process-oriented models, enterprises need to act like product companies that focus exclusively on delivering services to the actual clients with active engagement of all employees.
Principle 3: Strictly Follow End-To-End Responsibility
This principle makes every team member responsible for the entire life cycle of the product starting from planning to deliver the end-products in the online market securely.
Principle 4: Allow Teams to Function Autonomously
This principle stresses permitting teams to function independently throughout the product life-cycle. It will result in effective personal development and simultaneous growth.
Principle 5: Work towards Continuous Improvement
This principle aspires an enterprise to adopt the changing circumstances by bringing significant improvement in the product and services offered to the client.
Principle 6: Automate Everything in the System
Automation is the one-stop solution for the inclusion of continuous integration and deployment. Besides, it also brings entire infrastructure code in the cloud for efficient delivery of the product.
Boost Productivity through Powerful DevOps Strategies
DevOps strategy, as defined by Gartner clarifies that it is a customer-driven approach to offer better value for delivering effective app solutions. Gone are the days; when the developer works on a single project writing codes for numerous days. It resulted in delaying the deployment of the task among the users.
Why define strategies for DevOps? It is crucial to eradicate communication bottlenecks and stabilize the whole working environment with automation. Now, certain DevOps strategies will surely bring laurel to any reputed DevOps company. Let’s have a look at such robust strategies:
a. Infrastructure-as-a-Code (IaC) for Greater Automation
IaC act as a blessing in disguise to achieve complete automation in the IT environment. Moreover, it helps in the maintenance of your infrastructure in perfect shape. So, any deviation occurring in steady-state is easily solved by automation via the IaC solution.
b. Continuous Integration (CI)
CI helps in the total amalgamation of the changes done in the building up of the code. With the help of CI, developers can frequently merge the code to save ample time in the development cycle.
c. Continuous Delivery (CD)
CD helps in the development of high-quality software in a limited time. It also ensures that there is a speedy release of the software with minimum manual intervention. It is a powerful DevOps strategy that enhances the speed and frequency of providing software in the market.
d. Microservice Architecture
It is the latest trend that helps in solving complex applications in the IT environment. Microservices help in communicating with one another that helps in becoming your technology more agnostic.
e. Container Management System
Containerized application is the new strategy that moves the services away from virtualized to container systems. To improvise it, use Kubernetes that helps in managing the containers in the ecosystem and thus enables multi-tenancy on SaaS platforms.

Skills That Must be Part of DevOps Programmers
What is the utmost priority of DevOps developers? It is the delivery of high-value products in a short time frame. To make it possible, some kind of skills in respect to interpersonal and technical aspects is required to become successful. In other words, what a DevOps engineer needs is a combination of both soft and hard skills.
If you have experts in your kitty, it is well and good. If not, one can check those skills to improve and refine for their overall career development.
a. Communication & Collaboration Skill
To succeed in DevOps rivalry, one must possess very good collaboration and communication skills. It helps in breaking silos between teams and implements DevOps culture with great efficacy.
b. Security Skills
Without a secure environment, development and operational teams can’t keep data safe. So, DevOps engineers must integrate security with SDLC to make the whole procedure safe effectively.
c. Automation Skills
A DevOps engineer must have a good command over automation as manual working has taken the back seat. It is a skill that must be a part of the DevOps developer to automate the entire pipeline successfully.
d. Soft Skills
What does DevOps emphasize? It stresses more culture and people. So, people must have soft skills like listening, assertiveness, a positive attitude, and many others to deliver the work on time.
e. Coding & Scripting Skill
These are two crucial mindsets that DevOps engineers must have with them. So knowledge of programming/scripting languages such as Python, Java, PHP, node.JS will be helpful to accomplish goals efficiently.
f. Cloud Skills
Cloud and DevOps are inseparable in present times. While the DevOps drive process, the cloud provides a suitable platform to perform vital functions of code (test, deploy, and release).
g. Testing Skills
It is a vital skill as it will avoid failure in the DevOps automation pipeline. Learning testing skills will help developers to speed up the process and deliver quality apps to the end-users.
Thus, DevOps is the current topic that is creating a buzz in a business circle. Individuals have wrong interpretation: Is DevOps simply software? Or is it merely an app? Contrary to it, DevOps is a concept that is a combination of Dev and Ops teams that invest their whole energy to achieve a common goal.
DevOps does a wonderful thing: It brings processes and tools for people where they work together to create a united front for the benefit of the environment. Moving to DevOps is a journey! Based on DevOps philosophy, you can utilize its process, practices, workflow, and frameworks to create a secure network with high speed and minimum risks.
