Overview of PowerShell
- [Instructor] Let's get started by discussing PowerShell. Microsoft developed PowerShell in 2006 to address the limitations of the traditional Windows command line. Before PowerShell, system administrators found it challenging to automate tasks or manage complex systems efficiently using the built-in command line prompt tools. Originally called Monad, PowerShell was built on the .NET Framework, providing a solid foundation for scripting and programming. This allowed PowerShell to offer advanced capabilities beyond simple command execution, making it a powerful system automation and management tool. Powershell's evolution began with the first version in 2006, which laid the groundwork for advanced system management. With PowerShell 2 in 2009, Microsoft introduced remoting, a game changer for automating and managing multiple machines from a single session. PowerShell 3 was released in 2012, which introduced workflow automation, expanding its capabilities for handling large, complex processes. PowerShell 4 was released in 2013, which introduced Desired State Configuration, allowing admins to define configurations and ensure systems stay compliant. PowerShell 5 and 5.1 were released in 2016, which added new cmdlets and security features, reflecting Microsoft's commitment to continually improving the tool. PowerShell Core makes a significant milestone by becoming open source and cross platform. This opened the door for PowerShell to be used in Windows, macOS, and Linux, making it more accessible for broader range of IT environments. It was built on .NET Core rather than the traditional .NET framework. PowerShell Core could now run on more operating systems. This shift showed Microsoft's recognition of the growing importance of a multi-platform environment, allowing PowerShell to stay relevant in modern IT. In 2020, PowerShell 7 unified PowerShell Core and Windows PowerShell into a single platform, offering the best of both worlds. It was built on .NET Core 3.1. It delivered improved performance and introduced new cmdlets. PowerShell 7 was designed for system administrators and developers, bridging the gap between these roles. By offering better compatibility with older modules and enhancing its scripting and automation features. PowerShell 7 became a more powerful, versatile tool for managing cloud and on-premises environments. PowerShell 7 introduced several key features that improved its functionality. One of the first notable is pipeline parallelization, using for each object in parallel, which allows users to run commands faster and more efficiently. Compatibility with existing Windows PowerShell modules was also significantly improved, making the transition to PowerShell 7 smoother. Enhanced error handling with Error View and Error Action made debugging scripts easier, while tighter integration with cloud services and DevOps tools cemented PowerShell's role within the modern IT infrastructure. PowerShell has become more than just a scripting language. It is now a comprehensive automation framework. Its focuses on DevOps, cloud integration, and cross-platform support reflects the needs of today's IT environments. By continuously adapting, PowerShell remains a robust tool for automating processes, managing systems, and improving workflows. Whether you are a developer or a system administrator, understanding PowerShell's evolution helps you appreciate its full capabilities and how it can be leveraged in modern infrastructure. In our next video, we'll discuss the key features of PowerShell 7.
