Now that you understand how a hiring DevOps engineer helps an organization, let's look at their specific responsibilities. 

Continuous Integration and Continuous Delivery (CI/CD)

Create, design, and maintain a continuous integration and delivery pipeline using Jenkins, Gitlab, CircleCI, or AWS CodePipeline. A DevOps engineer can uncover ways to reduce deployment times from hours to minutes! Do you need a deployment this weekend? They can handle this as well, as long as you book it in advance!

Automate and Script Repetitive Tasks

Bash and Python scripting automate your infrastructure, servers, containers, cronjobs, and any other function that a DevOps engineer can document.

Maintain and Deploy Infrastructure

DevOps can use Terraform or Cloudformation to create new production environments. Furthermore, due of their expertise in Infrastructure as Code (IaC), they can maintain and deploy infrastructure using IaC tools.

Security and Hardening

DevOps can also handle security incidents including hacks, security audits, server hardening, and user security controls like AWS accounts, SSH keys, Linux/Unix privileges, permissions, SSL certs, encryption, and API key encryption (e.g., Amazon KMS).

Troubleshoot any Linux instance

Is the DNS a problem? Server? Networking? Is email not working? Perhaps an AWS DevOps Engineer can assist. After all, he is the Linux expert. As a Windows or.net-based app, he should be adept at managing Windows servers with similar duties.

Cloud Networks Tasks

DevOps understand how to link multiple VPC networks, handle networking difficulties, deploy VPN services, and construct virtual networks.

Dockerize Open Source Applications

The DevOps engineer develops microservice architectures for your enterprise SaaS application. Our blog on how to dockerize a Python/Flask program might be useful.

Kubernetes Clustering

A DevOps developer can use Amazon EKS, Azure KS, or Google KS to set up a production Kubernetes cluster. We've written an article about setting up a Kubernetes cluster on AWS that can help your DevOps engineer.
