Why do I need more than one VPC?
Using a Multi-VPC architecture allows you to isolate different parts of your infrastructure. Following the principle of divide and conquer simplifies and improves security due to less error prone and more precise access control.
How many VPCs can you have in AWS?
By default you can create up to 5 VPCs. You can ask for additional VPCs using the VPC Request Limit Increase form. You can now check the status of each of your VPN Connections from the command line or from the VPC tab of the AWS Management Console.
Are VPCs necessary?
VPCs are useful if your app needs to access servers outside of EC2, e.g. if you have a common service that's hosted in your own physical data center and not accessible via the internet. If you're going to put all of your web and DB servers on EC2, there's no reason to use VPC.
How many VPCs can you have in a region?
Although you can have up to five VPCs in a region, only the initial VPC that AWS creates for you can be the default VPC. Every VPC is associated with an IP address range that is part of a Classless Inter-Domain Routing (CIDR) block which will be used to allocated private IP addresses to EC2 instances.
How many VPC are in one account?
You can't have more than 255 gateway endpoints per VPC. This is the combined quota for the maximum number of interface endpoints and Gateway Load Balancer endpoints in a VPC. To increase this quota, contact AWS Support.

You can create a VPC using either the Runtime Manager UI, or the Anypoint Platform CLI. The Anypoint Platform base subscription includes two Anypoint VPC licenses, which entitles your Anypoint Platform organization to two VPCs.
What is the point of a VPC?
Amazon Virtual Private Cloud (Amazon VPC) enables you to launch AWS resources into a virtual network that you've defined. This virtual network closely resembles a traditional network that you'd operate in your own data center, with the benefits of using the scalable infrastructure of AWS.

Isolation and Traffic Segregation
- There is another consideration for the number of VPCs needed — the different groups of apps/APIs and the level of isolation required for each group. At this point, we need to talk about business groups and environments. Business groups are a great solution to separate and control access to Anypoint resources. A VPC is a resource that can be created...
Anypoint Platform Connectivity Considerations
- If you remember from my previous post, Anypoint Platform offers three connectivity methods to your data center: 1. IPSec VPN 2. VPC peering to your AWS VPC 3. Connection to your AWS Direct Connect location As we’ve seen earlier in this post, in some cases our data center is geographically distributed or has different locations. In those instances where more than one co…
