Cloud computing is evolving constantly with new business infrastructures joining the cloud infrastructure. With more complex networks and challenges faced by the consultants, it gives birth to ultra-modern features, functionalities, and resources that take us a step ahead towards the future. However, the cloud journey starts with choosing the right provider based on your business requirements.
There are majorly two supreme providers, Microsoft Azure and Amazon Web Services (AWS), and AWS is a pioneer in cloud infrastructure. Organizations looking for options to move their on-premise solutions to cloud infrastructure can choose either of the providers, but the majority of business owners go with AWS for the number of services, pricing, ease of access and support consultants across the world. For choosing AWS, there are several other benefits which we will discuss in our next post.
So, if you are wondering the difference between the Azure Virtual Network or Virtual Private Cloud then here are some of the similarities, differences, and benefits that you can explore in this post. The points mentioned below will enable customers in choosing the right cloud provider of their choice.
Conceptually, both the cloud infrastructure offers a rock-solid platform for businesses to run their business workflows. The same kind of building blocks is used in both the cloud platform with a certain degree of variance services, pricing and implementation model. Below are some of the major differences in the building blocks that you would like to focus on and understand before choosing the cloud platform for your business.
Both the cloud platforms use AWS VPC and Azure VNet to use non-globally routable CIDR as per the standards of RFC 1918. Azure supports different sizes of subnets, the smallest of the subnet supported is /29 and the largest is /8. AWS VPC offers Egress which is useful in blocking the incoming traffic while allowing outgoing traffic. AWS first started the IPV6 support before Azure, with access to Egress -only internet gateway. Azure Vnet offers better flexibility in the area of IP addresses of subnets and it can be changed after the initial designs.
In AWS the routing tables are used to specify and allow routes for outbound traffic from the subnets. All the subnets created from the VPC are automatically associated with the primary routing table, so all traffic can be routed through the subnets unless defined. In Azure Vnet you do not have to configure or manage the route as it offers subnet routing by default.
AWS VPC comes with two levels of security resources which are known as Security Group and Network Access Control (NACL). The SG is applied at the EC2 instance level and the rule is applied at Elastic Network Interface. NACL is used for applying stateless filters at the subnet level and every resource in the subnet.
Azure VNet offers security groups that combine the functions with AWS SGs and NACLs. The NSGs can be applied on the subnet level and only on one NIC. But with AWS you can apply more than one SG to an ENI.
AWS VPC uses three different types of gateways, and if you add NAT then it is four gateways. One of the gateways is used for connectivity to the IPV4 and Egress-only gateway. Another one is used for Virtual Private Gateway (VPG) to work with VPN or Direct Connect. For non-AWS networks, AWS offers CGW and last NAT gateway for various other purposes.
In Azure, you can find two types of security, i.e. VPN Gateway and ExpressRoute Gateway. The VPN gateway allows encrypted traffic for the private to private cloud network or private cloud to hybrid on-premise network using Microsoft’s backbone.
Both platforms come with superior and high-class services, but as discussed AWS holds an upper hand over cloud being the pioneer in the market. There are several services, implementation processes and flexibility offered by AWS which is still being looked forward to from Azure. Choosing AWS for a startup to existing business requirements has resulted in a profitable scenario for several clients.
