Powershell - Looping

 There may be a situation when you need to execute a block of code several number of times. In general, statements are executed sequentially: The first statement in a function is executed first, followed by the second, and so on.

Programming languages provide various control structures that allow for more complicated execution paths.

A loop statement allows us to execute a statement or group of statements multiple times and following is the general form of a loop statement in most of the programming languages −

Sprint Burndown At a Sprint-level, the burndown presents the  easiest way to track and report status  (the proverbial  Red / Amber / Green ), i.e., whether your Sprint is on or off-track, and what are the chances of meeting the Sprint goals.

This forms the basis for the Sprint Burndown chart. The total story points agreed at the beginning of the sprint make up the y-axis, and the individual dates in the Sprint make up x-axis. If your team do it right, then they would take in just the right amount of work into ...

  Terraform is an infrastructure as code tool that lets you build, change, and version cloud and on-prem resources safely and efficiently. HashiCorp Terraform is an infrastructure as code tool that lets you define both cloud and on-prem resources in human-readable configuration files that you can version, reuse, and share. You can then use a consistent workflow to provision and manage all of your infrastructure throughout its lifecycle. Terraform can manage low-level components like compute, storage, and networking resources, as well as high-level components like DNS entries and SaaS features. How does Terraform work? Terraform creates and manages resources on cloud platforms and other services through their application programming interfaces (APIs). Providers enable Terraform to work with virtually any platform or service with an accessible API. HashiCorp and the Terraform community have already written  thousands of providers  to manage many different types of resources...
