Knowledge with Hands-on Experience and Troubleshooting

Flow with respect to Networks in AWS which need to be clear to expose any application on AWS and having some of services in on-premises. I will compare AWS services with on-prem technology, so it become ease to understand.                                                           Building Block of AWS Networking VPC: Consider it as a switch place in multiple Data center and all switches are connected with each other we can further have small subnets on it which can be part of all switches or only one depend upon the planning and requirements. Route Tables : Each subnet we create in VPC can have each route table or all subnets have one, Route table is used to control the routing of subnets and how traffic will be routed for any workload on the subnets. Route table can be attached to few other services of AWS as per requirements. NAT Gateway: I...

I have knowledge and hands-on experience with PTCL and Alibaba cloud but for AWS till today it was just knowledge. Today we have created an IPSEC tunnel with AWS and our on-prem DC, Before starting the process i study some material which is shared by AWS and it was quite helpful to understand the flow. Below mentioned are the steps which one need to take before creating the tunnel. 1)Decide which CIDR/Subnet you will use over the cloud so at AWS end you can create a VPC with same CIDR. 2)List down your public IP which will be use for the tunnel end point at on-prem DC. 3) Get a Public IP at AWS end which in AWS language we call it Elastic IP. 4) Decide you will use public IP or private IP subnet for VPN tunnel inner packet headers. Steps which we follow for the deployment: 1)First step is to create a VPC in respective region at AWS and assign planned CIDR to it. You can further divide VPC into subnets with desire subnet mask.  2)Create customer gateway, it will contain the informat...
