What does VM Rightsizing mean?
VM rightsizing is an administrative process wherein system administrators optimize the allocation of resources within a virtualized hardware environment.
In general, virtual systems are set up to be as efficient as possible. However, common problems with the operation of virtual systems arise over time. Individual virtual machines (VMs) are supposed to have the right levels of processing power, memory and disk space. Sometimes, though, they do not use what has been allocated to them, which results in inefficiency.
In VM rightsizing, system administrators assess the virtual CPU processing power allocated to a VM. They also look at the assigned RAM and virtual disk space, and what the VM uses.
Although administrators can use manual VM rightsizing, there are software tools available that provide this kind of administration. These tools can either suggest manual pre-provisioning of resources or, in some cases, change the provisioning automatically. All of these strategies are subject to hardware and software requirements and must work with administrative schedulers and other software tools that support ongoing operations.

What does Cloud-in-a-Can mean?
A cloud-in-a-can is a single product that allows a company to deploy a private virtual environment protected by a firewall. Cloud-in-a-can products are intended to reduce the costs of setting up cloud infrastructure. Cloud-in-a-can solutions are usually a combination of software and the hardware needed to run it properly.
Cloud-in-a-can solutions are also referred to as cloud-in-a-box.
Cloud-in-can is a business IT solution that is intended to allow a company to set up a private cloud in a relatively short period of time. The company also reduces future compatibility issues by deploying a cloud with standardized architecture. Once the cloud-in-a-can is deployed, the company simply needs to integrate the cloud functions with the existing databases and software. Ideally, this streamlining significantly shortens the timeline to complete the implementation of a private cloud.
