Server Type Server type	App. Name Name of the application (optional)	Number of VMs Number of Virtual Machines (VM) in your environment	CPU Cores Number of CPU cores per virtual machine (also referred to as vCPU). AWS provides instances with up to 32 vCPUs	Memory(GB) Amount of Memory required for your application. AWS provides instances with up to 256 GiB of memory	Hypervisor Type of Hypervisor used	Guest OS Guest OS is the operating system installed in the virtual machine	DB Engine DB Engine for Server type	VM Usage (%) If you don't need your virtual machines up and running 24/7 you can save lot of money by powering them off when not being used. VM usage rate = % of time your VM is running: 30% utilization over a 3 year period = 10.8 months, implying your VM is running a total of 10.8 months over a 3-year period. If you don�t know your actual usage, the tool defaults to 100%, which means that your VM is running 24/7/365 over a 3 year period. The tool uses this value to determine the most cost-effective Amazon EC2 pricing model (On-Demand or Reserved Instances).	Optimize By Since the configuration of Amazon EC2 instance types is fixed, you need to map your VMs to one of the available EC2 instance types. There are three options available- 1. Optimize by vCPU count: this option matches your on-premises VMs to EC2 instances by CPU count 2. Optimize by RAM: this option matches your on-premises VMs to EC2 instances by memory 3. Optimize by Storage IO: this option matches your on-premises VMs to EC2 Storage Optimized instances. If you don�t know which parameter to select, start with memory first.	Virtualization Host Virtualization host is the physical server that runs the hypervisor and VMs. The tool provides two options - a 2 processor 96 GB RAM server and a 4 processor 256 GB RAM server. The host configuration determines how many VMs you can run per server.

Utilization (%)

If you don't need your servers up and running 24/7 you can save lot of money by powering them off when not being used. Server Utilization = % of time your server is running: 30% utilization over a 3 year period = 10.8 months, implying your server is running a total of 10.8 months over a 3-year period. If you don�t know your actual usage, the tool defaults to 100%, which means that your server is running 24/7/365 over a 3 year period.

Storage Type Type of on-premises storage used- storage area network (SAN), which provides block level data storage, network-attached storage (NAS), which provides file level data storage, and object storage, which manages data as objects. On-premises SAN and NAS systems are mapped to Amazon EBS, while object storage is mapped to Amazon S3.	Raw Storage Capacity Raw storage capacity is the disk volume in the box while usable capacity is the capacity available to application after RAID protection and formatting. RAID is used to provide data protection, e.g. using a RAID 10 implies that only 50% of the raw physical storage purchased is available to applications as usable storage. AWS storage that is calculated is not equal to the amount of raw physical storage capacity, but rather a percentage of the storage that is actually utilized for on-premises data storage (usable storage).	% Accessed Infrequently PercentageDownloadedPerMonth	Disk Type DiskType	Max IOPS for Application Max input/output operations per second (IOPS). Typical HDD provide ~100 IOPS, while SSDs provide much higher IOPS. Amazon EBS standard volumes provide ~ 100 IOPS on average, while you can stripe multiple EBS Provisioned IOPS volumes together to achieve up to 48,000 IOPS (Provisioned IOPS volumes support up to 30 IOPS per GB).	Backup % / Month Amount of data that changes every month and needs to be retained to support near-term business continuity. For the first backup, a full copy of your data is saved to a tape system. For each incremental backup, only the changed part of your data volumes is saved.

Data Center Bandwidth (Mbit/s)

Network Bandwidth for your data center to the internet (data centers have 1Gbps/10Gbps or higher data rates WAN links). Maximum bandwidth for some common internet access technologies includes Fast Ethernet (100Mbit/s) and Gigabit Ethernet (1Gbit/s). Tool uses this data to calculate inbound/outbound data transfer, e.g., a 1Gbps bandwidth implies ~309 TB of data transfer/month.

Peak/Average Ratio

Ratio of peak traffic to average traffic. A peak/average ratio of 3 is fairly common
