What is DevOps ♾ - Explained in Details

✅ We will start from the very beginning, when the software development was hard, and developers had to do everything on their own, and developing a simple app, took years.
📝 Developing software required at least two teams, developers (programmers) and the operations team.
📝 Developers had to plan, design and build the software, whereas the operations team, took the already built software, created the infrastructure and implemented the software there.

👍 Multi-Stage Build Images used in CICD ♾

➡️ Every microservice should be its own separate container. If you only use a single-stage Docker build, you’re probably missing out on some powerful features of the build process. On the other hand, a multi-stage Docker build has many advantages over a single-stage build for deploying microservices.

➡️ Some Advantages are :
- Optimizes the overall size of the Docker image
- Removes the burden of creating multiple Dockerfiles for different stages
- Easy to debug a particular build stage
- Able to use the previous stage as a new stage in the new environment
- Ability to use the cached image to make the overall process quicker
- Reduces the risk of vulnerabilities found as the image size becomes smaller with multi-stage builds

Horizontal vs Vertical Scaling 🚀


➡️ Horizontal Scaling (Scaling Out)
Instead of upgrading a single machine, we add more machines or servers to share the load.

✅ Some benefits of horizontal scaling are: helps us to enhance reliability (no single point of failure), better load distribution, simple to implement, costs less, fewer points of downtime.


➡️ Vertical Scaling (Scaling Up)
We upgrade our existing servers/machines with more powerful hardware such as more memory, CPU, storage, etc.

✅ Some benefits of vertical scaling are: are simple to manage (fewer servers to handle), faster performance for specific tasks, and no need to reconfigure systems for multiple servers, less complicated maintenance.
