DevOps for beginners: Insights
DevOps in literal sense is made up of two words Development and Operations. As we can make out from its name, it brings together software development and the It operations team which work together in sync to increase the efficiency and the delivery time of their product which maybe a website or an app. we will discuss all about devOps for beginners in this blog.
It is not a tool, program or a language which can be learned, rather it is a set of practices or a mindset which cuts down the product development cycle and improves the quality of the end product.
Devops: what is it?
DevOps is generally represented by an infinite cycle which denotes the never ending process of development of the product. New features have to be added and regular checks for bugs is mandatory so the cycle never actually stops.
What DevOps actually does is that it makes the whole process quite smooth. The transition from the development stage to the operations is easier as the whole team is aware of the development stage of the product. The strong communications between the two teams is what matters here.
Phases of DevOps
Broadly there are 8 steps or stages involved
The business owners and the software developers sit together and discuss about the requirements and the goals of the website or the application.
Different coders design and write codes using editors and store it in tools like github.
The codes are then combined into a single repository to build the software.
Series of testing is done to check for errors and loopholes.
Using Jenkins or other similar automation servers the whole code is brought together with new features.
The application or the site is released to production server.
The operations teams checks for security and configures servers.
Regular checks for any irregularities is made and the functioning is tracked.
How does it work?
Conventionally the two teams would work individually ad perform their specific tasks. The Development team performs operations like writing code, designing new features and running tests. Whereas the operations team is responsible for managing servers, traffic on their site or app and also sometimes security and backup.
Merging these two teams into one which then work together from the initial stage of coding , testing and finally deployment of the model is how DevOps takes place.
Why is it useful?
Since it is basically a set of practices and not a new technology many people wonder that what’s the use of this concept.
The collaboration cuts down the time it takes for handing over the project from one team to other. Since both of the teams are involved from the beginning it takes less time for the finished product to be delivered.
Earlier the Ops team would have to handle the security issues single handedly and run multiple. Now the joined efforts results in better features as most of the process is shifted to automation.
Better features, better designs, improved security and rapid delivery is synonym with a better product.
The users will definitely chose the product which is better and revised. DevOps will allow the owners to release new features quickly which will garner more attention as users are attracted to new features.
Delivering more in less time will be helpful in increasing the total productivity as more projects could be taken up. Exponential expansion in the It sector is what it leads to.
Model for adopting DevOps for beginners.
It aims at filling the gaps between the developers and the customers. Instead of developing the project in one go and then sending it for reviewing, a prototype is made which is sent to the customer who then communicates the changes which can be applied easily. It results into a satisfied customer because of the constant feedback and a quicker delivery.
The workflow is smooth as this models allows changes to be done within the development cycle. There is no need to start all over again and write codes and run tests.
This approach aims at simultaneous working of two teams in collaboration for early delivery of the project.
If you want to pursue career in DevOps and call yourself a DevOps engineer it is important to know what happens in every phase of the development cycle. Learning only certain tools is not enough you have to go through the whole process and understand how the two teams merge and come up with a product which is faster, better and efficient.
