Development: This refers to the process of creating, designing, coding, and testing software applications. It involves writing the actual code that makes up the software and includes various stages like analysis, design, implementation, and testing. Developers are responsible for building the software according to the specified requirements and ensuring its functionality, performance, and security.

Operations: Operations, also known as IT Operations or Ops, deals with managing the infrastructure and environment in which the software runs. It includes tasks such as deployment, configuration, monitoring, maintenance, and troubleshooting. The operations team ensures that the software runs smoothly, is available to users, and performs well in production environments.

Development Team Technologies:

Programming Languages: Developers use various programming languages depending on the nature of the project. Some popular programming languages include Python, JavaScript, Java, C#, Ruby, Go, and PHP.

Integrated Development Environments (IDEs): IDEs provide developers with tools and features to write, debug, and test code efficiently. Examples include Visual Studio Code, IntelliJ IDEA, Eclipse, and PyCharm.

Version Control Systems: Version control systems like Git, SVN, and Mercurial are used to manage and track changes to the source code, enabling collaboration and code versioning.

Continuous Integration (CI) Tools: CI tools like Jenkins, CircleCI, Travis CI, and GitLab CI/CD automate the process of building, testing, and validating code changes regularly to catch integration issues early.

Operations Team Technologies:

Configuration Management Tools: Configuration management tools like Ansible, Puppet, and Chef automate the setup and maintenance of server configurations, ensuring consistency across the infrastructure.

Infrastructure as Code (IaC): IaC tools like Terraform and AWS CloudFormation enable the definition and management of infrastructure through code, making it reproducible and version-controlled.

Monitoring and Logging: Tools like Nagios, Prometheus, Grafana, and ELK Stack (Elasticsearch, Logstash, Kibana) are used to monitor server and application performance, collect logs, and analyze data.

Cloud Platforms: Operations teams work with cloud providers like Amazon Web Services (AWS), Microsoft Azure, Google Cloud Platform (GCP), and others to manage cloud-based infrastructure.

Virtualization: Technologies like VMware and Microsoft Hyper-V are used to create and manage virtual machines in virtualized environments.

Security Tools: Operations teams use various security tools, such as intrusion detection systems (IDS), firewalls, and vulnerability scanners, to enhance the security of the infrastructure.
