VPC / AWS Architecture Diagrams

Today we’re creating a Virtual Private Cloud (VPC) and an architectural diagram of our VPC.

We have our Classless Inter-Domain Routing (CIDR) notation identified as 10.0.0.0/16. What this means is that the VPC will include IP addresses between the ranges of 10.0.0.0 through 10.0.255.255. Within our VPC, we’ve created subnets which is commonly associated within specific Availability Zones. These subnets are labeled as public because we want them to be accessed from the internet. Private subnets are subnets that backend instances use so that it can be accessible to other instances (servers) but should not be directly accessible from the internet.

Secondly, we’ve throw in our application load balancer. A load balancer allows tasks to be distributed in an attempt to maintain efficiency and availability. The App Load Balancer operates on Layer 7 (HTTP) of the OSI Model and supports the redirect between unsecure and secure traffic (HTTP to HTTPS). With our application load balancer, we’ve included Auto-Scaling; which is the process of monitoring applications and adjusting workload resources for optimal performance at a smaller cost.

Now, below is how our diagram should look.
