Cloud Impact

This tool is used to compare the on-premises infrastructure with the different options offered by cloud hosting providers. This makes it easy to analyse the possible economic and ecological gains.

Cloud Impact Dashboard

When arriving at the Cloud Impact tool, a dashboard is presented. This contains two graphs.

Cloud Impact Graph

The Cloud Impact graph is intended to provide a quick comparison of the different regions available from hosting providers.

Each point on the graph corresponds to a region of a host (the regions of the same host are of the same colour) and by passing the mouse over it, you can access the data allowing you to place the regions on the graph:

• Associated costs (expressed in $ per year) ;
• The associated carbon emissions (expressed in kg of CO2 equivalent per year).

Clicking on one of the dots takes you to the Cloud Impact Details screen of the associated region.

Cloud Pricing Graph

A second graph is present at the bottom of the page. This one displays only the regions in ascending order of cost. Its advantage is that it allows you to add to the comparison hosts that have not published their carbon data.

The columns of the graph act in the same way as the points on Cloud Impact graph: moving the mouse over them gives access to the costs of the region (expressed in $ per year).

Clicking on one of the columns takes you to the Cloud Impact Details screen of the associated region.

Cloud Impact Details

This screen allows you to have a more detailed view of a particular region, and to modify various parameters (annual or monthly costs, types of invoicing, currency used, use or not of recommendations ).

It is divided into several parts:

Details of costs and emissions

Tiles are present at the top of the screen. They show the costs and emissions and, thanks to the coloured notches, make it possible to see at a glance whether or not savings are being made in terms of costs or emissions.

The sections are as follows:

For costs :

• Compute Costs: cost of virtual machines ;
• Storage Costs: cost of storage.

For broadcasts :

• Grey Emissions ;
• Compute Emissions: actual emissions from virtual machines.

Download buttons are also present, allowing you to download the details per virtual machine

Virtual machine detail graphs

A graph is present on the right side of the screen. It allows to group virtual machines by type of instance, according to 3 data: type of operating system, costs, and emissions. This allows you to see at a glance which type of instance is responsible for high costs or high emissions.

Details per virtual machine

A final section at the bottom of the page provides complete information for each virtual machine. This section has two tabs: an "Infrastructure Costs" tab and an "Infrastructure Emissions" tab.

For each of them, a table summarises its characteristics for each instance. It is also possible to retrieve this table in CSV format by clicking on the download buttons.

Data calculation

Mapping of on-premises virtual machines to cloud instances

The component tries to match the compute and storage capacities of on-premises VMs with the services offered by cloud providers (AWS, Google Cloud, Azure, ...).

Recommendations

DCScope recommendations can also be used in the component. Simply check the "Apply recommendations" box at the top of the screen. With this option you will be able to see the cost of virtual machines in the public cloud if you follow the recommendations for:

• Resize vCPU and vRAM in virtual machines.
• Deactivation of inactive virtual machines.

For virtual machines with recommendations to "turn off or delete the virtual machine if not used", the cost provided by Cloud Impact with recommendations is only the cost associated with the storage requirements of the virtual machine, as the compute cost of a disabled virtual machine is 0
