Comparison Between AWS and AZURE
The world of storage space is dominated by AWS and Azure with Google cloud slightly behind .In this section we will examine which features of AWS and Azure are good and what makes them appealing to user by using different parameters.
If we have to use Computing as parameter then below is differences between both of them
| Feature | Amazon EC2 | Azure |
| Virtual machines | Instances | Virtual machines |
| Images | Amazon Machine Image | VM Image (both boot-disk-only and full machine) |
| VM templates | AWS Cloud Formation | Azure Resource Manager |
| Automatic instance scaling | Auto Scaling | Azure Autoscale |
| Supported VM import formats | RAW, OVA, VMDK, and VHD | VHD |
| Deployment locality | Zonal | Regional (equivalent to Cloud Platform zones) |
| Preemptible VMs | Yes | Yes |
| Incremental snapshots | Yes | Yes |
The next criteria that we shall use is Virtual machine types Below table will highlight the differences
| Machine Type | Amazon EC2 | Azure |

| Compute-optimized | c6g.medium – c6gd.metal c5.large – c5d.metal c5a.large – c5ad.24xlarge c5n.large – c5n.metal c4.large – c4.8xlarge | F2s v2 – F72s v2 F1 – F16 F1s – F16s |
| Storage-optimized | i3.large – i3.metal i3en.large – i3en.metal d2.xlarge – d2.8xlarge h1.2xlarge – h1.16xlarge | L8s v2 – L80s v2 L4s – L32s |
| GPU | p4d.24xlarge p3.2xlarge – p3db.24xlarge p2.xlarge – p2.16xlarge inf1.xlarge – inf1.24xlarge g4dn.xlarge – g4dn.metal g3s.xlarge – g3.16xlarge f1.2xlarge – f1.16xlarge | NC6 – NC24 NC6 Promo – NC24r Promo NC6s v2 – NC24s v2 NC6s v3 – NC24s v3 NC4as T4 v3 – NC64as T4 v3 NP10s – NP40s NV6 – NV24 NV12s v3 – NV48s v3 ND6s – ND24s ND40rs v2 |
| High performance | n/a | H8 – H16m H8 Promo – H16mr Promo HB120rs v2 HC44rs |
Next criteria is Networking ,in this criteria we shall compare both
| Product | Amazon Web Services | Microsoft Azure |
| CDN | Amazon CloudFront | Azure CDN |
| Dedicated Interconnection | AWS Direct Connect | ExpressRoute |
| DNS | AWS Route 53 | Azure DNS |
| Load Balancing | Elastic Load Balancing | Azure Load Balancer |
| Virtual Networks | Amazon Virtual Private Cloud | Azure VNet |
The next criteria would be Locations around the world AWS cloud network locations are available in 24 regions, 77 zones, 210 network edge locations, and 245 countries and territories and corresponding number for Azure is Azure cloud network locations are available in 60+ regions and 170 network points of presence (PoP).
Next criteria is DNS service . A DNS service is used to convert human-readable domain names into the IP addresses used by servers to communicate.Below table will highlight the differences between both
| Feature | Amazon Route 53 | Azure DNS |
| Zone | Hosted Zone | DNS Zone |
| Support for most DNS record types | Yes | Yes |
| Any-cast-based serving | Yes | Yes |
| Latency-based routing | Yes | No |
| Geography-based routing | Yes | No |
| DNSSEC signing | Yes | No |
| Private Zones / Split Horizon | Yes | Yes |
