AWS 3Tier Architecture

Create role for EC2: Creating VPC: VPC is created to have a virtual private cloud which is used to keep our cloud network separate from other cloud networks. Creating Subnets: Since the 3tier atchitecture has 3 sunets in 2 AZs so we need to create 6 subnets. In each AZ we need to create 2 private subnet and one public subnet. Creating Internet Gateway: In order to have communication with the internet we must have an internet gateway. Creating NAT gateways: NAT gateway is created in public subnets and it helps the private subnet to connect with the internet. Creating Route Tables: Route tables are tables that define the route between services. This helps the data in a specified path. Create Route tables and edit the routes accordingly and associate the subnets. Creating security groups: Creating subnet group for database: creating database: Creating EC2 instances: Creating connection with DB: Inserting data in the database: Creating a bucket and uploading objects: Downloading the s3 objects in the machine Creating an Image Creating a target group: Creating internal load balancer: Launch template creation: Creating a Auto scaling group: Creating a WebTier instance: Uploading the files and accessing: After creating webtier instance now we are accessing the web tier in the server Creating target group for Internet facing load balancer Creating a Internet facing load balancer Creating launch template for WebTier Creating Auto Scaling group for Webtier
