DevOps is becoming more and more important for the IT industry. Because automation is speeding up processes, similarly small, mid, and large-sized businesses are shifting from manual and traditional processes to a more modern approach.
These approaches, such as DevOps, are advantageous for companies not only in terms of work speed but also, in terms of cost.
What is DevOps?
DevOps is considered an agile development approach that combines both the development team and the IT department. Combining both operations enhance communication and team collaboration.
Additionally, it also improves the engagement of all the team members involved. All of these above-mentioned factors, collectively, add to the team’s productivity. One major aspect of DevOps is the automation of manual processes which brings in more efficiency.
Difference between DevOps and Traditional Development
- It involves documentation for a better understanding of the products’ infrastructure
- DevOps believes in working in iterations therefore, it involves continuous software delivery
- Through DevOps, work is less complicated to manage
- It leads to faster resolution time for development or other related problems
- DevOps ensure the productivity of teams
- It leads to higher employee satisfaction and engagement
- More growth and development opportunities
- Features and updates are delivered much faster than initially timed or anticipated
- It makes the development environment more stable
- Higher and improved levels of communication and team collaboration
- Faster delivery gives the team more time to innovate
- Unlike DevOps, traditional IT operations are slow which may delay the initial launch
- It may have a lack of team coordination, mutual teamwork which may cause serious problems between teams
- Less transparency and flexibility since its traditional
- Less ownership and accountability
- Developers may be less efficient and productive due to a lack of transparency
- Lack of paperwork can lead to misunderstandings and confusion
Now that we have briefly gone through the difference between both traditional It operations and DevOps, it’s time to see how we can implement DevOps from scratch:
How to implement DevOps from scratch?
Learn about DevOps methodology
Implementing DevOps methodology is the very first and the most important step for implementing DevOps from scratch. It includes continuous Integration (CI) and continuous delivery (CD). without knowing these core processes, the development process cannot process further.
Learn programming languages
DevOps include the knowledge of programming languages. Because only then DevOps engineers are able to understand the system and find ways to effectively manage it.
If we look at some of their roles and responsibilities, we will know that the DevOps team introduces processes and methodologies to automate the development life cycle from initial coding to final maintenance and upgrades.
Therefore, one of the many responsibilities of DevOps is to write code so if they lack the necessary knowledge about a related programming language chances are that their code is full of errors and bugs, fixing which can be extremely costly and time-consuming.
They should know about the programming languages such as java, c, c#, python, and ruby including some additional scripting languages to get started.
Understanding different operating system
it’s pretty much obvious that if you know the programming language you should also know about the operating systems you are writing the code for.
Because knowing about the operating system will make you more efficient and productive during the development process. Also, you would have all the necessary knowledge about memory and disk usage which as a result will make you write the code faster.
Know about the cloud technology
Cloud technology is becoming the new trend. The reason why it has become extremely important for developers and DevOps engineers to learn about cloud technologies as well if they are to succeed with their product development.
Moreover, due to the increase in demand, companies are switching to cloud tech for maximum security. The need for cloud technology experts is also increasing, and therefore the job openings. The reason why DevOps should know about cloud technologies as well including the cloud technology programming languages.
Understanding about security
Companies deal with sensitive customer data every day. Not just any data but credit card information, personal information et al, which when breached can leave irreparable damages to the company both in terms of financial and reputational.
Also, if your company can not protect customers’ data, chances are you will lose both your existing and your new customers. Keeping data secure is also one of the responsibilities of DevOps developers.
They are responsible for making sure that tools for data security and protection are implemented. They ensure that data security is also automated and risky or weak entry points, from where hackers can attack the system are also properly sealed.
Now how can they ensure the product’s security – they can make sure the IP address is masked or protected, there is TLS encryption, routing, firewalls, DNS, etc. to keep the information encrypted.
Also, they need to make sure to follow the protocols and standard rules of networking like HTTP, SSL, DNS, FTP, TCP/IP, etc.
