How do you know where an AWS Networking Engineer will be at the next networking event? Just check the next record in the Route Table! Now that I have almost killed the mood with that atrocious joke, allow me to deliver the finishing blow with the presentation my latest AWS networking project. This project was…
AWS Project: access an S3 bucket from an EC2 instance in a private subnet using a VPC Gateway Endpoint. The EC2 instance does not use the public internet to access the bucket, but instead uses the AWS backbone network. This means that traffic from the EC2 instance in the private subnet to the S3 bucket…
Another AWS networking project for your amusement. Connecting two EC2 instances that are located in different regions WITHOUT using the public internet. VPC peering is used to connect to EC2-B-private from EC2-A-private. VPC peering uses the AWS backbone network so traffic does not traverse the public internet; both EC2 instances have private IPs. A route…
AWS Project: VPC with a public subnet containing a NAT gateway. The NAT gateway can be used for outbound traffic to the internet from the EC2 instance in the private subnet. A route table connects the destination 0.0.0.0/0 to the internet gateway for the public subnet. In the public subnet, there is an EC2 instance…
Extracting data from an AWS RDS MySQL database, storing it locally as a CSV and uploading it to S3. This can be done doing a full load (“extract_mysql_full.py”) or an incremental refresh (“extract_mysql_incremental_binlog.py”) using binlog. In my case, binlog needed to be set up within AWS RDS MySQL by turning on automated backups, creating a…
AWS Networking Project: VPC with a public and a private subnet and an internet gateway. A route table connects the destination 0.0.0.0/0 to the internet gateway for the public subnet. In the public subnet, there is an EC2 instance that can be accessed via SSH through the correct security group settings.Using the EC2 instance in…
How do resources in different subnets within the same VPC communicate with each other? Route tables to the rescue. EC2 A in subnet A (CIDR 10.0.0.0/24) and EC2 B in subnet B (CIDR 10.0.1.0/24) are both in the same VPC. They can communicate with each other because the main route table contains a route with…
Some time ago I shared that I would try to broaden my knowledge in the networking department. True to my word, I finished my first networking project: deploying an EC2 instance (a sort of virtual machine) in a public subnet within an Amazon Virtual Private Cloud (VPC). A VPC is like a cloud network environment…
Een cloud reserveringssysteem waarbij potentiele klanten op een website een datum en tijd kunnen selecteren, een emailadres in kunnen voeren en vervolgens een bevestingsmail in hun inbox krijgen. De infrastructuur is ontwikkeld met behulp van een S3 Bucket (static hosting), een Lambda Function, een DynamoDB tabel, een API Gateway en Simple Email Service. CloudFormation is…
Some time ago I developed a reservation system using AWS CDK. Potential customers can visit a website that contains a calendar, click on a date, click on a time and finally, enter their email address. A confirmation email will be sent to their address right after the reservation. I built this infrastructure using an S3…
