Considering a Migration to Cloud?



We’re here to help.
Our exclusive Private Cloud Calculator tools powered by CloudPhysics allow you to get a firm understanding of your workloads as configured as well as rightsized based on memory and CPU usage.  These metrics can then be applied against cloud models to make an intelligent Apples-to-Apples comparison.

Cost Calculator Overview

Cost Calculator

This 12-minute video summarises the capabilities of the CtC, CloudPhysics cloud cost comparison calculators. Bear in mind that the cost calculator now supports Google Cloud Platform (GCP) as well as Azure and AWS

Leverage the Cost Calculator for On-Premise IT analytic card to customise and create your data centre cost profile. This is used to provide the comparison to the major public clouds.

Run immediate “what if” analysis on right-sizing initiatives at peak, 95%tile & 99%tile. Understand the financial implication of right-sizing your environment in minutes.

Webinar: Save More Than 50 Percent on Your Migration to Cloud by Rightsizing

This webinar shows how the correct tooling can answer some of the most challenging questions when considering a migration to the Cloud:

  • Which cloud is best for my workloads?
  • How can I maximise my savings?
  • Where are my ‘quick wins’ and how do they match to common Cloud instances?

This two-minute video walks you through setting up the CloudPhysics Observer.


CloudPhysics is a SaaS-based platform that brings the power of Big Data analytics to virtualized data centers, enabling IT to make data-driven operational decisions. It consists of two key elements: a lightweight, secure virtual appliance (“Observer”) and a web-based portal. After you deploy an Observer to your environment, it collects, scrubs, anonymizes, encrypts and streams operational metadata to the CloudPhysics platform where you can run pre-made analytics packages (called “Cards”) or your own custom analytics against this data. No data leaves your environment without being anonymized and secured.


What data is collected?

Configuration and performance metadata are collected from the following VMware objects:

  • VMs
  • Hosts
  • Clusters
  • Resource pools
  • Datastores
  • Networks
What about identifying information or sensitive data like usernames and passwords?

The Observer does not collect any data other than specified. In addition, CloudPhysics excludes sensitive information such as usernames, passwords, IP addresses, and MAC addresses from transfer by default − these are never sent, in any form, to CloudPhysics.

Is data secured for streaming to CloudPhysics?

Yes! All collected data is strongly encrypted using SSL 3.0/TLS 1.0 when streaming to CloudPhysics.

Can the Observer be set up to use a proxy?

The Observer supports proxy usage via HTTPS and no firewall modifications are needed, provided port 443 is allowed for use to the hosts, either directly or via proxy. Proxy credentials are stored inside the virtual appliance in an obfuscated text format in a configuration file.

Does CloudPhysics communicate with or send data down to the Observer?

The virtual appliance is routinely patched and updated automatically from CloudPhysics for maintenance and feature updates.

Does CloudPhysics make any changes to my environment?

CloudPhysics never makes changes to your environment.

Does anything besides the Observer have to be installed?

For most customers, the Observer is the only thing that needs to be deployed. For those who want to run the Cache Assessment Card, CloudPhysics will deploy a VMware-format, digitally-signed host VIB (VMware Installation Bundle) for virtual disk statistics collection. This is a host daemon which installs only in userworld.


How is data secured once it is received by CloudPhysics?

Once collected, your anonymized scrubbed data is securely stored in CloudPhysics’ systems.  Physical and network security are maintained to ensure only correctly authenticated access to your data.

  • Unused protocols are blocked with network firewalls and edge routers
  • Internal firewalls are used to limit data to its respective application tier
  • User and customer CloudPhysics credentials are securely hashed (SHA-512) with a 192-bit random salt
Who has access to my data once it’s on the CloudPhysics platform?

Only you − or someone you invite to your CloudPhysics account − can see and run analytics against your data.

Is any of my data shared with anyone?

Only you can give access to your data by inviting new users to your account or by engaging a third party and explicitly providing access to your data. This access is read-only or to run analytics against the data − never to manipulate the data. You have the ability to grant or revoke visibility permissions and can remove access permission at any time.

CloudPhysics does not share individually-identifiable information with third parties without explicit direction from our users and customers.

Does CloudPhysics use my data in any way other than for my own use?

Non individually-identifiable data may be queried by CloudPhysics to provide system-wide analytics (such as comparing your VM uptime to the CloudPhysics community) − but it’s never shared with any third party.
