Day 1: What is DevOps
This is the #90DaysofDevops challenge under the guidance of Shubham Londhe.

What is DevOps?
DevOps is the combination of cultural philosophies, practices, and tools that increases an organization’s ability to deliver applications and services at high velocity: evolving and improving products at a faster pace than organizations using traditional software development and infrastructure management processes. This speed enables organizations to better serve their customers and compete more effectively in the market.
DevOps combines development (Dev) and operations (Ops) to unite people, processes, and technology in application planning, development, delivery, and operations.
What is Automation?
Automation is the creation and application of technologies to produce and deliver goods and services with minimal human intervention. The implementation of automation technologies, techniques and processes improve the efficiency, reliability, and/or speed of many tasks that were previously performed by humans.
Automation is being used in a number of areas such as manufacturing, transport, utilities, defense, facilities, operations, and lately information technology.
What is Scaling?
Scaling involves beginning with only the resources you need and designing your architecture to automatically respond to changing demand by scaling out or in.
As a result, you pay for only the resources you use. You don't have to worry about a lack of computing capacity to meet your customer's needs.
There are two types of scaling :
1) Horizontal scaling
Horizontal scaling refers to the process of increasing capacity by adding more servers or systems to a network. This can be done by adding new servers that are independent of the existing ones, or by using load balancers to distribute traffic across multiple servers.
2) Vertical scaling
Vertical scaling refers to the process of increasing the capacity of a single server or system by adding more resources such as CPU, memory, or storage. This can be done by upgrading the hardware on the existing server, or by adding additional servers that are connected to the main server in some way.
What is Infrastructure?
Infrastructure is viewed as code that can be managed and maintained through the use of automation and configuration management tools. This means that rather than manually configuring and maintaining infrastructure, the infrastructure can be defined and managed using code and automation tools. This enables the infrastructure to be treated in the same way as the application code, with the ability to version control, test, and deploy infrastructure changes alongside application code changes. Managing infrastructure in this way can help to improve the reliability, scalability, and security of the infrastructure.
Why DevOps is Important?
DevOps aims to bridge the gap between development and operations teams and to automate many of the processes involved in software delivery.
Someone has written a piece of code in a development environment (laptop) and the DevOps engineer's responsibility is to move this code to its destination (Customer). Along the way, there will be repositories to manage, test to conduct, and pipelines to build. There will be tools to manage certain tasks, automation to save time and manual errors, and infrastructure to create. Monitoring and alerting to build confidence.
Reduced time to market
One of the key reasons why DevOps is important for your business is that your software can be delivered faster thanks to streamlined processes, proper automation, systematic release planning, and more.
Faster Innovation
You can innovate faster than your competitors thanks to faster product delivery to the market. The DevOps culture also allows the team to offer ground-breaking ideas more freely and share their thoughts in continuous communication.
Increased efficiency in development
Software engineers do not need to spend time on tasks that are perfectly automated in DevOps. The amount of manual work is minimum. Parallel workflows, acceleration tools, scalable infrastructure, continuous integration servers, and much more contribute to efficient development and reliable deployment.
Higher Reliability
The development, deployment, and other processes become more predictable and error-free. With shorter development cycles ensured by DevOps and continuous testing, the team can spot any inconsistencies or defects in the software in a timely manner. Thanks to good collaboration and exchange of experience, it’s easy to quickly resolve them. It’s also incredibly easy to roll back a deployment at any time.
Customer Satisfaction
Another huge reason why DevOps is important is that the customer-centric approach, regular feedback, faster delivery to the market, and constant improvement all contribute to the most satisfying results in software development.
