What are the Differences between containers and VMs ?
During Deployment activity phase the environment building is part of the DevOps practices.
In traditional method we used to spend lot of time for this task. But when it came with VMs and containers, it is easy and in minutes the environments can be prepared using the IAC.
The containers became very popular for building the test environments. Let us say you want to build a MYSQL server, the solutions is; simply try to understand its environment and pull one Docker image which has the MYSQL. Then use it in that network environment.
When we talk about the VMs and Containers one need to understand their differences. I have made a video for learners:
If you are a Docker learner, then try to build the MYSQL container from the below specifications:
AWS and GCP Conducts different certification for different roles playing.
Being the top Cloud services competitors globally, they have different prioritized technologies implemented for Cloud services. AWS is matured enough by occupying the cloud gamut as 1st service provider in implementing them, years together. Where as GCP is accelerating their services year on year on the technologies those are in demand. Similarly it has evolved with professional certifications also accordingly.
You can see the comparison video from the below link:
In continuation of my previous blog on; DevOps:Advanced DevOps Practices/Processes-1: Following are the some of the DevOps concepts, a Practitioner need to practice.
What is the goal of DevSecOps?
The goal of DevSecOps is to decrease time to market while cutting the costs of development and remediation, while improving overall application security.
How it can be performed ?:
If the appropriate, automated security vulnerability and configuration scanning tools are deployed, developers with varying skill sets and experience can find and fix security problems as they occur.
How to motivate developers?:
Teaching developers on secure coding practices is still essential, as it is monitoring and protecting the production environment.
How to achieve it?:
By integrating automated application security testing as part of the moving into DevSecOps practices, teams can complete a DevOps security checking that addresses the challenges associated with developing secure applications in agile environments.
How to apply checkpoints?:
There are tools to verify the above checks.
I have discussed some of the relevant points on this subject in the below video session:
