What are the different use cases for AWS VPC in the area of Data Analytics?

Asked 2021-Jun-15 at 07:40

I am new to AWS VPC and exploring everything about it. I understood that VPC is majorly used to have a secure and isolated environment. What are the different use cases for AWS VPC in the area of Data Analytics? I have a data lake pipeline currently which is as follows:

Extract data using APIs
Store raw data in S3
Create Lambda functions or Glue Jobs to perform business metrics
Store metric outputs in S3
Create tables in Athena for all the data stored in S3
Import tables in Quicksight to produce business insights from visuals

In this process how can VPC be used or make this process efficient/better?

The services you mention (mostly) live outside of VPCs.

VPCs are used for services that use virtual computers, such as Amazon EC2 computers and Amazon RDS databases.

By using services that don't involve specific 'computers' (such as Amazon S3, Athena, QuickSight) you can take advantage of much lower costs, paying only what you use. These services do not mimic traditional servers and therefore don't need VPCs. All the networking complexity is hidden and you can concentrate on using the service instead of running a network.

Yes, VPCs add extra security, but that's only because resources on a VPC need securing due to potential security holes. The services you mention are all secured via IAM and do not expose themselves outside the published APIs.

QUESTION

What is the difference between WAF and security Group

Asked 2021-Jun-14 at 15:13

I Would like to understand what is the difference between WAF, Security Group, and a routing table. Let's say I have a VPC, 2 subnets (a private one) and I want to deploy a web application (UI and backend service and a database (RDS)), In this scenario where does WAF and security groups come into the picture. Can someone help me to understand a use case?

ANSWER

Answered 2021-Jun-14 at 15:13

HTTP protocol is built on top of the TCP protocol.

WAF inspects the HTTP traffic before it reaches your web application in order to block malicious web traffic. In order to implement WAF in front of a containerized application (running on ECS for example) or in front of an application running on EC2 you should use an Application Load Balancer in front of the application servers and associate the WAF with that load balancer. If your application runs on Lambda you can do the same but using API Gateway.

A Security Group accepts or blocks networking protocols such as TCP, UDP, ICMP - based on ports. Open up port 443 and 80 if you want to expose your web application.

Routing tables should be associated with your subnets so that the network traffic (TCP) can knows where to go.

Best practice is to put your application servers and databases in private subnets (with routing tables that does not route traffic from the Internet) and then put e.g Application Load Balancer in the public subnets in order to accept traffic from the Internet and route it to your private subnets.

Does AWS alb/elb logs or vpc flow logs, contain the body of the user's POST request?

Asked 2021-Jun-14 at 08:32

I just want to postmortem an incident that happened in my application server running on AWS. We already enabled alb logs and vpc flow logs. The application accepts a user's request in post method with data in body. Now I am confused: Does AWS alb/elb logs or vpc flow logs, contain the body of the user's post request? Or if not, where can I access the logs which contains request's body data?

Note: The application server is inside an auto scale group behind alb, so logs from the instance level would not be possible.

Unkown failure to associate VPC connector in service project with shared VPC subnet in main project

When trying to associate a VPC connector in a service project with a shared VPC subnet in another project (From the same organization) the following error appears:

...

ANSWER

Answered 2021-Jun-13 at 06:32

To create a Serverless VPC Access Connector using a Shared VPC first create the subnet in the Host Project of a Shared VPC with CIDR 28, there has to be a unique subnet for each Connector.

Then follow Googles Documentation Configuring the host project if using Shared VPC, specifically the following sections.

1. Create Firewall Rules

we have to also create firewall rules to allow requests from the following IP ranges to reach the connector and to be reached by the connector:

NAT ranges 107.178.230.64/26 and 35.199.224.0/19

Health check ranges 130.211.0.0/22, 35.191.0.0/16 and 108.170.220.0/23

2. Grant Permissions

Also for each service project that will use VPC Connectors, a Shared VPC Admin must grant the Compute Network User role (compute.networkUser) in the host project to the service project cloudservices and vpcaccess service accounts.

There are two EC2 windows instance placed in same VPC and same public subnet having same security group. I want to check if both are able to communicate with each other using ping command. I have added rules at both security group and NACL level. ALL ICMP is also been included exclusively other than "all" traffic. but I am not able to test the same. kindly suggest if there is any other way I can check connectivity between two ec2 windows instances?

If the two EC2 instances are in the same VPC, Subnet, and Security Group you just need to check that the following is in place:

Security Group allows inbound ALL ICMP is from self (self reference the security group id)
Security Group outbound ALL TRAFFIC is allowed.
Subnet has a route to LOCAL in the VPC

GKE Internal Ingress for Headless Service

Asked 2021-Jun-11 at 11:12

I'm trying to create an internal ingress for inter-cluster communication with gke. The service that I'm trying to expose is headless and points to a kafka-broker on the cluster.

However when I try to load up the ingress, it says it cannot find the service?

ANSWER

Answered 2021-Jun-11 at 11:12

Setting up ingress for internal load balancing requires you to configure a proxy-only subnet on the same VPC used by your GKE cluster. This subnet will be used for the load balancers proxies. You'll also need to create a fw rule to allow traffic as well.

Have a look at the prereqs for ingress and then look here for info on how to setup the proxy-only subnet for your VPC.
