I have always worked with Linux Systems and thus Bash was my go to tool for some specific tasks. But now I am much more aware with Python than Bash as it does give me better grasp on things. I am not saying that for server scripting, Bash can not do some tasks. It can be used in a vast area of things to solve. But I am now comfortable with Python more.
Recently, I did stumble upon of a task that was related to comparing two huge CSV files.

I do have to manage SSH config files with numerous host entries. And also there is ansible involved. So, there is redundant host management involved. Managing 4,5 host information in SSH and Ansible inventory files is not that tiresome. It gets very repetitive and boring when the host’s number is the magnitude of that.
This problem motivated me to have a tool that will help one to manage numerous hosts from a single place.

Containerization gives us many benefits from packaging to distribution and others. Thus, Docker is widely used as a containerization tool which is designed for running specific tasks and processes, not for hosting operating systems or like other virtualization tools like VMWare, VirtualBox etc. You create a container to serve a single unit task. Once it completes the given task, it stops. The container life-cycle depends on the ongoing process inside of it. Once the process stops,

I have been working with redis and python for sometime. It is fun to play with python and redis. There are so many things can be solved by redis.
- Session persistency
- Volatile Datastore
- Job or Message Queue
And many more. But recently I was thinking about using it as main database. I am not yet sure what kind of problem I might face or what things to optimize when it is about scalability or reliability. I will for sure share my experience.
Here I want to talk about –

I mostly use Python Flask when I need to develop a Web App or API.
Why? Because it is:
- Very Flexible
- Micro-Service Friendly
- Fast Development
These are one of the main reasons I choose Flask. But mostly I love to code with Flask. There are so many ways to run flask applications. I will write some of them here with code examples.
