1.It is the capacity to change the size, power, or capacity of a system to handle a changing workload without compromising performance or architectural integrity.2.An instance state defines the current operational phase or lifecycle status of a virtual machine, object, or data entity within a computing system.3. type of scaling,Vertical ScalingHorizontal ScalingFeatureVertical Scaling (Scale Up)Horizontal Scaling (Scale Out)Core ConceptMaking a single machine bigger and stronger.Adding more machines to work as a team.LimitLimited by the maximum capacity of single hardware.Virtually limitless as you can keep adding nodes.DowntimeOften requires a reboot or brief downtime for upgrades.Zero downtime (load balancers distribute traffic dynamically).Failure Risk Single point of failure (if the main server crashes, the app goes down). High fault tolerance (if one node crashes, others take over).

4.A hibernate instance does not clear its memory, whereas a stop instance does clear its memory.

Nirai Anbu porchezhian · Answer

The main nature of scaling is to dynamically adjust compute resources to match changing workload demands, ensuring high availability and cost efficiency.

An instance state defines the current operational condition of a virtual server (such as running, stopped, or terminated), indicating whether it is actively processing workloads or powered off.

Vertical scaling increases or decreases the power (CPU/RAM) of a single instance, whereas horizontal scaling increases or decreases the total number of instances.

A hibernated instance does not clear its memory because it saves the RAM contents to the root volume before shutting down, whereas a stopped instance flushes and clears its memory entirely.
