aws Setup AWS Network Firewall What is it?AWS Network Firewall is a managed firewall service for our VPC. We can use Network Firewall to filter traffic at the perimeter of our VPC. Network Firewall includes filtering traffic going to and coming from IGW, NAT Gateway, VPN and Direct Connect. Network Firewall components Firewall Firewall
aws ASA to AWS asymmetric routing - BGP By default, instances that we launch into an Amazon VPC can't communicate with our on-prem network. We can enable access to our network from the VPC by creating an AWS managed Site-to-Site VPN connection, and configuring routing to pass traffic through the connection. A single Site-to-Site VPN connection consists of
aws Site-to-site VPN between AWS and Palo Alto (non-BGP) In this blog post I will show you how to configure site-to-site VPN between AWS VPC and Palo Alto Firewall. AWS offers two VPN tunnels between a virtual private gateway or a transit gateway on the AWS side, and a customer gateway on the remote side (Palo Alto in our
aws AWS NAT Gateway High Availability What is a NAT Gateway?NAT Gateway enables instances in a private subnet to connect to the Internet but external services cannot initiate a connection with those instances. Private vs Public subnetThe instances in the public subnet can send outbound traffic directly to the Internet via Internet Gateway (IGW), whereas
aws AWS Transit Gateway AWS Transit Gateway (TGW) is a service that enables customers to connect their Amazon VPCs and their on-premises networks to a single gateway. With AWS Transit Gateway, you only have to create and manage a single connection from the central gateway in to each Amazon VPC, on-premises data centre, or
terraform AWS VPC deployment with Terraform Terraform is a tool for building, changing, and versioning infrastructure safely and efficiently. We can use Terraform to design, implement and manage the AWS infrastructure. There are many articles out there explain this in detail so I will dive straight into the example. If you want to learn Terraform basics,
terraform Terraform Data Sources Terraform defines datasources as: Data sources allow data to be fetched or computed for use elsewhere in Terraform configuration. Use of data sources allows a Terraform configuration to make use of information defined outside of Terraform, or defined by another separate Terraform configuration.In simple words, let's say you have
terraform Terraform Remote State Terraform state Terraform must store state about your managed infrastructure and configuration. This state is used by Terraform to map real-world resources to your configuration, keep track of metadata, and improve performance for large infrastructures. This state is stored by default in a local file named "terraform.tfstate" (shown below)
aws AWS VPC flow logs AWS defines flow log as: VPC Flow Logs is a feature that enables you to capture information about the IP traffic going to and from network interfaces in your VPC. Flow log data can be published to Amazon CloudWatch Logs or Amazon S3. After you've created a flow log, you
terraform Terraform + AWS I recently started working with Terraform and decide to write a post about it. This would be an introduction to managing AWS using Terraform. Terraform helps to automate the deployment of servers and other infrastructure on AWS.ScenarioLet's say we need to create VPC, public subnet, route table, Internet gateway
aws Amazon Elastic Block Storage Amazon Elastic Block Storage provides durable, persistent block-level storage. AWS EBS is designed to be used with EC2 instances, connected as their disk storage volumes. EBS volume comes with redundancy built in which means the data is not lost if an individual drive fails. Note - EBS volume lives entirely
