As of recent updates, Application Load Balancers do support AWS PrivateLink. You can create an endpoint service in your VPC and specify an ALB as the service provider. This allows you to offer the applications behind your ALB privately to other VPCs through AWS PrivateLink. If there are any specific documentation you can refer i can help you better where they have mentioned dropping support.

Hi, Great explanation. Quick question...in your diagram, provider side, target for network load balancer is instances. For instance, if I am creating an endpoint service for Athena, what should be the target for network load balancer?
@Pythoholic
6 ай бұрын
When creating an endpoint service in AWS, particularly for a service like Athena which is a serverless, managed service by AWS, you don't typically manage the network load balancers (NLBs) directly. AWS manages the networking layer for Athena, so you don't provision an NLB for Athena in the same way you would for EC2 instances or your own services. However, if you are integrating Athena with your VPC and you want to create a private connection between your VPC and Athena, you would use AWS PrivateLink. Here's the general idea of how it works, without specifically targeting an NLB for Athena: 1. **AWS PrivateLink**: This service allows you to privately access AWS services like Athena from your VPC, without using public IPs, and without requiring the traffic to traverse the internet. 2. **Endpoint Services**: With AWS PrivateLink, you create an endpoint service in your VPC. This service doesn't directly expose an NLB for you to target; instead, it allows the service provider (in this case, Athena) to accept connection requests. 3. **Interface VPC Endpoints (or Interface Endpoints)**: You create an interface endpoint in your VPC. This is represented as an ENI (Elastic Network Interface) with private IPs in your VPC. This endpoint connects to the endpoint service for Athena, allowing your applications in your VPC to access Athena privately. 4. **DNS Names**: AWS generates DNS names that you can use to reference the Athena service. These DNS names resolve to the private IPs of the interface endpoint, keeping traffic within the AWS network and your VPC. In summary, instead of targeting an NLB for Athena, you would use AWS PrivateLink to create an endpoint service and an interface endpoint in your VPC. This setup provides private connectivity to Athena, without exposing services to the public internet.

@Pythoholic
6 ай бұрын
Your approach makes sense, and you're on the right track with using AWS PrivateLink to access Athena in Account B from Account A. Here's how you can structure this setup: 1. **Endpoint Service in Account B (Service Provider Account)**: - In Account B, you create an AWS PrivateLink endpoint service. - Although Athena itself doesn't have a traditional network load balancer that you would target, you can create an endpoint service for Athena. - This endpoint service won’t require you to specify network load balancers as targets. Instead, AWS manages the underlying infrastructure. 2. **Permissions**: - In Account B, you need to set up the appropriate permissions so that Account A can create a connection to the endpoint service. 3. **Interface VPC Endpoint in Account A (Service Consumer Account)**: - In Account A, you create an interface VPC endpoint (AWS PrivateLink) for the endpoint service that you created in Account B. - When you create this interface VPC endpoint, you specify the service name of the endpoint service from Account B. - This doesn't involve setting up traditional targets for a load balancer, but rather, it involves creating a secure, private connection to the service in Account B. 4. **DNS Configuration**: - After creating the interface endpoint in Account A, you will use the DNS names associated with the interface endpoint to access Athena. The DNS names resolve to private IP addresses in your VPC, keeping the traffic internal and secure. 5. **Testing and Validation**: - After setting up, test the connectivity and permissions by querying Athena from Account A, ensuring that the query goes through the PrivateLink setup and that the necessary permissions are correctly configured. This setup leverages AWS PrivateLink for private connectivity and doesn't require you to manage network load balancers for Athena. AWS handles the underlying infrastructure, making sure that your connection between Account A and Athena in Account B is secure and private.

let's say you have a service running in one region that needs to access a service running in another region. You can create an AWS PrivateLink endpoint for the service in the second region and configure your first region's VPC to use that endpoint. This allows your service in the first region to securely access the second region service without needing to establish VPC peering between the two regions.

@Pythoholic

Testing the accessibility of an endpoint on an EC2 instance can be done using various methods, with `wget`, `telnet`, `curl`, and `ping` being some of the common ones. The choice depends on what you want to test (just reachability, specific service availability, etc.): 1. **Ping**: - Use `ping` to check the basic reachability of your EC2 instance. - Command: `ping ` - Note: ICMP requests must be allowed in your EC2 instance's security group and network ACLs. Some servers disable ICMP/ping responses. 2. **Telnet**: - Use `telnet` to test the connectivity to a specific port on your EC2 instance. It's useful for checking if a particular service (like SSH, HTTP) is listening on the expected port. - Command: `telnet ` - Note: If the connection is successful, the port is open. If not, it's either closed, or a firewall is blocking access. 3. **Wget or Curl**: - Use `wget` or `curl` for testing HTTP or HTTPS endpoints. These tools are more specific for web services and are useful for checking if a web server is serving content. - Commands: - `wget ` - `curl ` - Note: These tools can also provide information about the response headers, which can be useful for debugging. 4. **Nmap**: - Use `nmap` for a more comprehensive scan to see which ports are open and what services are running on those ports. - Command: `nmap ` - Note: Be cautious with `nmap` as it's powerful and can be intrusive. Ensure you have the proper permissions to use it on the network. 5. **Netcat (nc)**: - Use `netcat` as an alternative to `telnet` for checking port connectivity. It's also useful for debugging and analyzing the network. - Command: `nc -vz ` Remember: - Before testing, ensure that your EC2 instance's security group and network ACLs allow inbound traffic on the ports you're testing. - Some services might be bound to a specific interface. Make sure the service you're trying to reach is configured to listen on the interface you're connecting to (e.g., publicly accessible). - For HTTP/HTTPS services, checking the application's logs can also provide insights if you're able to access the instance but are experiencing issues with the service itself.

Can It work between two different aws account? like one account serves as consumer and another account serves as provider?
@Pythoholic
Жыл бұрын
Yes, AWS PrivateLink can work between two different AWS accounts, with one account serving as the consumer and the other account serving as the provider. AWS PrivateLink enables you to securely access services hosted on AWS privately over the Amazon network. It allows you to establish private connectivity between VPCs (Virtual Private Clouds), VPC endpoints, and AWS services. This private connectivity ensures that traffic remains within the AWS network and does not traverse the public internet. When it comes to cross-account connectivity, you can set up AWS PrivateLink in a way that allows a consumer account to access services provided by a different account. The provider account would host the service or resource, and the consumer account would establish a VPC endpoint to connect to that service. Here's a high-level overview of the steps involved: 1. Provider Account: - Create and configure the service or resource that you want to expose to other AWS accounts. 2. Consumer Account: - Create a VPC endpoint in the consumer account's VPC, specifying the provider's service and the provider's account ID. - Ensure that appropriate route tables and security groups are set up to allow traffic to flow between the consumer VPC and the provider service. 3. Testing and Access: - Once the VPC endpoint is established, resources within the consumer account's VPC can access the provider's service or resource using private IP addresses. The traffic between the consumer and provider remains within the AWS network, offering enhanced security and performance. By leveraging AWS PrivateLink and establishing VPC endpoints between different AWS accounts, you can achieve secure and private connectivity for services across accounts, enhancing data protection and minimizing exposure to the public internet. It's important to note that both the consumer and provider accounts must have the necessary permissions and configurations in place to enable cross-account communication and establish VPC endpoints.

@Pythoholic
Жыл бұрын
When you use a VPC Endpoint (specifically for S3), it allows your EC2 instance to connect to S3 without traversing the public internet. The VPC Endpoint provides a direct, private connection between your VPC and the supported AWS service (in this case, S3). However, the VPC Endpoint only handles the network connectivity aspect. It does not grant permissions to perform actions on S3. For that, you still need IAM roles or IAM user credentials. So, if an EC2 instance in your VPC wants to access an S3 bucket, you would typically: 1. Create a VPC Endpoint for S3 to ensure private connectivity. 2. Attach an IAM role to the EC2 instance with the necessary permissions to access the S3 bucket. In summary, even after setting up a VPC Endpoint for S3, you still need to create and assign an IAM role to your EC2 instance to grant it permissions to access and perform actions on S3.

Yes, the principle applies to other AWS services as well. The VPC Endpoint (or PrivateLink) primarily addresses the network connectivity aspect, ensuring that traffic between your VPC and the AWS service does not traverse the public internet. However, the VPC Endpoint does not handle permissions. For permissions, you still rely on AWS Identity and Access Management (IAM). For example, if you have an EC2 instance in your VPC that wants to access an RDS database, a DynamoDB table, or any other AWS service: 1. You can create a VPC Endpoint for that specific service to ensure private connectivity. 2. You still need to attach an IAM role to the EC2 instance (or use IAM user credentials) with the necessary permissions to access that specific AWS service. In summary, regardless of the AWS service you're connecting to, if you're using a VPC Endpoint for private connectivity, you'll still need IAM to manage permissions and access controls.

The approach might be different but the underlying concept is same. In concept, AWS VPC Endpoints and Azure Private Endpoints serve similar purposes: they both allow you to privately access services within their respective cloud environments without traversing the public internet. However, there are some differences in implementation and features: ### AWS VPC Endpoints: 1. **Types**: Two types - Gateway Endpoints and Interface Endpoints. 2. **Services Supported**: Limited to specific AWS services like S3, DynamoDB for Gateway Endpoints, and various others for Interface Endpoints. 3. **Networking**: Operates within a VPC (Virtual Private Cloud). 4. **DNS**: Custom DNS names are not typically provided; you use service-specific DNS endpoints. 5. **Pricing**: Charged based on the data processed. ### Azure Private Endpoints: 1. **Types**: One general type that can be used for multiple Azure services. 2. **Services Supported**: Broad range of Azure services and also supports Azure Load Balancer. 3. **Networking**: Operates within a VNet (Virtual Network). 4. **DNS**: Provides a private IP and a custom DNS name. 5. **Pricing**: Generally charged based on the number of private endpoints. So while they aim to solve the same problem, the way they go about it can differ.

As per my understanding it's used to share resources within the organisation but if there is a term for resource sharing with third-party organisation I need to check that, I haven't come across that situation

How can we use AWs private link with AWs EKS.I have created a NLB which can talk to endpoint service. How should I proceed further ?

Using AWS PrivateLink with Amazon EKS (Elastic Kubernetes Service) involves creating an interface VPC endpoint for your services running on EKS, so they can be accessed privately within your VPC or from other VPCs. Since you've already created a Network Load Balancer (NLB) that can communicate with the endpoint service, you're partway there. Here's how you can proceed further: 1. **Create an Endpoint Service Configuration**: - Navigate to the VPC Dashboard in the AWS Management Console. - Go to the "Endpoint Services" section and create a new endpoint service. - Select your NLB as the service load balancer. This will make the Kubernetes services, which are exposed via the NLB, available as an endpoint service. 2. **Create a VPC Endpoint**: - Still in the VPC Dashboard, go to the "Endpoints" section. - Create a new Interface VPC Endpoint. - Choose the service name of the endpoint service you just created. - Select the VPC and subnets where you want the endpoint to be accessible. - Security groups attached to your VPC endpoint should allow traffic to the port your EKS service is running on. 3. **Configure DNS if Necessary**: - By default, AWS provides a DNS hostname for the endpoint. - If you require a custom DNS name, you might need to create a private hosted zone in Route 53 and associate it with your VPC. 4. **Update Your Application or Clients**: - Modify your application or clients to use the new VPC endpoint to communicate with the EKS service. This ensures that traffic between your VPC and the EKS service does not traverse the public internet. 5. **Verify Connectivity**: - Test the connectivity to ensure that your setup is correctly configured and that your EKS services can be accessed via the VPC endpoint. 6. **Monitor and Log**: - Consider enabling VPC Flow Logs for your VPC endpoint to monitor and log the traffic that is reaching your EKS services. - Regularly check CloudWatch metrics and logs to ensure the health and performance of your services. By using AWS PrivateLink, you're enhancing the security of your architecture by ensuring that the traffic between your services and EKS does not go over the public internet. This setup is beneficial for compliance and can reduce the exposure of your services to potential threats.

@Pythoholic Thank you so much for the detailed approach, I have created an endpoint, slightly confused on how should I test my connectivity now? I have created an nginx deployment whose service is an NLB which is connected to AWS private link and that is connected to endpoint. How should I test the flow ?

Testing the connectivity in your setup involves ensuring that your Nginx deployment is reachable through the AWS PrivateLink you've set up. Here’s how you can test the flow step by step: 1. **Identify the DNS Name or IP of the Endpoint**: - After creating your VPC endpoint connected to the AWS PrivateLink, AWS provides a DNS hostname for the endpoint. You can find this in the VPC dashboard under the 'Endpoints' section. Note down the DNS name. 2. **Test Using a Client Within the Same VPC**: - If you have an EC2 instance or any other resource within the same VPC as the endpoint, you can test the connectivity from that resource. - Use a tool like `curl` to send a request to the Nginx service: ``` curl ``` - You should receive the default Nginx welcome page or the content you've configured Nginx to serve. 3. **Test From a Different VPC (If Setup for Cross VPC Access)**: - If your VPC endpoint is configured to be accessible from other VPCs, you can test it from a resource in another VPC. - The security group of the endpoint and the route tables in both VPCs should allow the traffic. 4. **Check Security Groups and Network ACLs**: - Ensure that the security groups attached to your endpoint allow inbound traffic on the port Nginx is listening on (usually port 80 for HTTP or 443 for HTTPS). - Also, check the network ACLs for any rules that might be blocking the traffic. 5. **Access Logs or Monitoring Tools**: - If you have access logs enabled for your Nginx service or if you're using monitoring tools, check them to see if they register the requests. This can provide clues in case the connectivity test fails. 6. **Troubleshooting**: - If you're not getting the expected response, verify that your Nginx service is running correctly and is configured to respond to requests on the NLB's listener port. - Double-check the configuration of your NLB and ensure it's correctly forwarding requests to your Nginx pods. Remember, testing network connectivity can sometimes involve trial and error, especially with complex architectures. If the initial test doesn't work, review each component's configuration to ensure they're correctly set up to communicate with each other.

@@Pythoholic Again, thanks a ton for your help. I was clueless before. The thing m blocked now is I am unable to understand the subnets and security grp settings while creating Endpoint. I am able to see the az in which there are public, private and eks private subnets which one should I select for the creation of endpoint. My gut feeling says it should be either private or eks private but it is getting confusing. On the security grp, should I create a new security grp or use the existing ones from the VPC ? and for the route I know the port of my service but what should I put in the source?

You're on the right track thinking about using either private or EKS private subnets for your endpoint, and your considerations about security groups are also crucial. Let's break down these decisions to clarify your options: ### Subnets for Endpoint Creation When you create an endpoint for AWS PrivateLink, the general recommendation is to place it in **private subnets**. This ensures that the traffic to and from your endpoint does not traverse the public internet, aligning with the purpose of using PrivateLink for secure, private connectivity. - **Private Subnets**: These are not directly accessible from the internet, making them a secure choice for your endpoints. They allow your services to communicate with the endpoint without exposing them to the public internet. - **EKS Private Subnets**: If you have dedicated subnets for EKS that are private, these are also a good choice, especially if your EKS clusters are the primary consumers of the service exposed via PrivateLink. This setup minimizes internal network latency and keeps traffic within the AWS backbone. Choosing between private and EKS private subnets often comes down to your network architecture and where the consumers of the PrivateLink service are located. If the primary consumers are within your EKS clusters, EKS private subnets are ideal. ### Security Group Settings Security groups act as a virtual firewall for your resources to control inbound and outbound traffic. When configuring a security group for your endpoint: - **Create a New Security Group**: If you want to have specific rules that apply only to the endpoint, creating a new security group is advisable. This allows you to tailor the rules to the specific needs of the endpoint without affecting other resources. - **Use Existing Security Groups**: If your existing security groups already define the necessary rules for the endpoint traffic, you can reuse them. This approach is simpler but ensure that the rules in the existing security group are appropriate for the endpoint. ### Route Table and Source Port Configuration When setting up the endpoint, you'll specify the VPC and subnets, but typically, you won't modify the route table directly for the endpoint itself. AWS manages how the endpoint routes traffic to your services. Your focus should be on configuring the security group rules correctly: - **Port Configuration**: Ensure that the security group associated with your endpoint allows inbound traffic on the port your service is using. For example, if your service is listening on port 80, you should allow inbound traffic on port 80. - **Source for Security Group Rules**: The source in your security group rules depends on who will be accessing the service through the endpoint. - If the access is from within the same VPC, you can specify the VPC's CIDR or the specific subnet CIDRs as the source. - If the access is from other VPCs (in case of VPC Peering or if shared across accounts via Resource Access Manager), specify the CIDR ranges of those VPCs or use security groups from those VPCs as the source, if supported. By carefully choosing your subnets and configuring your security group, you ensure that your AWS PrivateLink setup is secure, efficient, and tailored to your application's needs.

The service Provider can provide a private DNS name for the endpoint service name however the name must be verified. AWS Private Link docs provide instructions how to do it.
