Cloud security is a constant concern and tends to revolve around common themes - how do you give intended users access to the data and systems their clearance allows, while maintaining a good user experience; and how do you keep unintended users or malicious bots out? In the entanglement of systems, services, and applications that make up a modern IT infrastructure, this is a lot harder to balance in practice than it is on paper.

In the realm of virtualization, snapshots play an integral role in managing virtual machines (VMs). Essentially, a snapshot captures the state of a VM at a specific point in time, providing a reference point to which you can revert if necessary. This can be especially handy when implementing changes to your VM or its applications, allowing you to quickly undo the changes if they cause any unforeseen issues.

When you survey developers on how to improve engineering practices and their daily job experience, their answers invariably include getting rid of little annoying things - what's called toil. Toil is manual and repetitive tasks that waste your time. Toil is arguably worse than crisis, because a crisis is temporary and firefighting can feel rewarding when it's over. Toil is more like a death march - an insidious force that eventually leads to burnout.
