How to start my career in DevSecOps?

DevSecOps and Cloud (AWS and OCI)

Before starting/changing career in DevSecOps field, you need to understand your passion and technologies, as DevSecOps is the combination of cultural philosophies, practices, and tools (like infrastructure as a code, configuration management, login and monitoring) that increases an organization’s ability to deliver applications and services at high velocity: evolving and improving products at a faster pace (any thing and every thing as a code or automated, almost no manual interaction other that configuration and approval) than organizations using traditional software development (doing manual deployment which will tack as usual more time and error pron) and infrastructure management processes. This speed enables organizations to better serve their customers and compete more effectively in the market.

In DevOps model, development and operations teams are no longer "siloed", similarly now these day DevSecOps, where DevOps and Security teams are no longer "siloed". Sometimes, these three teams are merged into a single team where the engineers work across the entire application life-cycle, from development and test to deployment to operations, and develop a range of skills not limited to a single function with consider all security concerns.

In some DevSecOps models, quality assurance and security teams may also become more tightly integrated with development and operations and throughout the application life-cycle.

Benefits of DevSecOps

Speed (Speed of Infrastructure / Application / Security changes)
Move at high velocity so you can innovate for customers faster, adapt to changing markets better, and grow more efficient at driving business results. The DevSecOps model enables your developers and operations teams to achieve these results. For example, microservices and continuous delivery let teams take ownership of services and then release updates to them quicker. Speed only will achieved in cloud not in op-premises.

Rapid Delivery (with DevOps and CI tools)
Increase the frequency and pace of application or infrastructure or security releases so you can innovate and improve your product faster. The quicker you can release new features and fix bugs, the faster you can respond to your customers’ needs and build competitive advantage. Continuous integration (CI), continuous testing (CT) and continuous delivery (CD) or continuous deployment (CD) are practices that automate the software release process, from build to deploy.

Ensure the quality of application updates and infrastructure changes (with blue and green technologies) so you can reliably deliver at a more rapid pace while maintaining a positive experience for end users. Use practices like continuous integration (CI), continuous testing (CT) and continuous delivery (CD) or continuous deployment (CD) to test that each change is functional and safe. Monitoring, performance testing and logging practices help you stay informed of performance in real-time.

Operating and managing your infrastructure and development processes at scale with any cloud provider (AWS or OCI). Automation and consistency help you manage complex or changing systems efficiently and with reduced risk. For example, infrastructure as code (with help of tools like Terraform and Ansible) helps you manage your development, testing (with Jmeter, Protector or Selinum), and development, qa, user acceptance testing (UAT), production environments in a repeatable and more efficient manner. You can scale horizontally or vertically in cloud as per your need.

Improved Collaboration
Build more effective teams under a DevSecOps cultural model, which emphasizes values such as ownership and accountability. Developers, security and operations teams collaborate closely, share many responsibilities, and combine their workflows. This reduces inefficiencies and saves time. For instance: reduced handover periods between developers, security and operations, writing code that takes into account the environment in which it is run.

Move quickly while retaining control and preserving compliance, including application, application data (storage), networking (network security group, security list, rules and firewall. What we need to do just automate compliance policies, fine-grained controls, and configuration management techniques. For instance, using infrastructure as code (IaaC or IaC) and policy as code, you can define and then track compliance at scale.

Implementing DevSecOps is only possible using various tools and technologies:
Automated build tools – Jenkins, Travisci.
Provisioning and Configuration Management, like Ansible, Puppet, Chef.
Monitoring & Alerts e.g. Amazon CloudWatch, ELK stack, Graphite.
VMs and Containers for development and production environment consistency e.g. Vagrant, Docker.

All in all, what you need to know, learn DevSecOps tools like Ansible, Terraform, Packer, Jenkins, Nexus, Sonar, Jmeter, and many more and double your salary. You can enrolls few courses with best price while clicking respective links Jenkins (Mastering in Jenkins with other Tools) or Packer, Terraform, Jenkins and Vagrant in AWS Cloud (5-In-1) or Terraform for AWS by Examples or Ansible Hands On in On-Premises & AWS Cloud Environments or Git (Bitbucket) in Unix or Windows or Packer (Product of HashiCorp) Images from Scratch in OCI All these course has been designed considering beginner to expert level.
