AWS VPC Security Best Practices

by Valts Ausmanis · October 5, 2024

Unless you are fully committed to using serverless approach to run your applications and workloads, you are most likely using AWS VPC to define your own virtual network for launching AWS resources (such as EC2 instances, load balancers, RDS databases, NAT gateways, etc.). Securing your AWS VPC and its resources is crucial for protecting your cloud infrastructure and data. I have compiled 19 best practices to help you secure your VPC environment effectively. From choosing the right VPC type to monitoring network traffic, these tips will provide a solid foundation for maintaining a robust and secure cloud environment. Let's get started!

AWS Internet Gateway vs NAT Gateway Overview

by Valts Ausmanis · September 26, 2024

Both the AWS Internet Gateway and NAT Gateway are essential networking resources that ensure your VPC resources, like EC2 instances, can communicate with the public internet. The main difference between the two is that the Internet Gateway enables both inbound and outbound communication with the internet, whereas the NAT Gateway only plays a role in outbound communication. Let’s now take a closer look at the differences between these two and when to use each of these resources.

AWS ALB vs NLB overview

by Valts Ausmanis · September 16, 2024

Regardless of whether you are planning to build a traditional server-based application or a container-based one, there is a strong chance you will need a proper load balancer to distribute incoming traffic across multiple targets, such as EC2 instances or specific IP addresses. Both the AWS Application Load Balancer and Network Load Balancer can handle large amounts of incoming traffic, scale accordingly, and provide high availability for your application. However, there are several important differences between these two that I will discuss in detail in this article, which will help you choose the right one for your use case.

AWS VPC Interface Endpoint vs Gateway Endpoint

by Valts Ausmanis · September 4, 2024

AWS VPC endpoints enable you to connect privately to AWS managed services and VPC endpoint services. There are two types of VPC endpoints: Interface Endpoints and Gateway Endpoints. Both allow you to use private IP addresses to connect with the service's resources, ensuring that traffic between the Amazon VPC and the service doesn’t leave the AWS network. To understand when to use an interface endpoint versus a gateway endpoint, let’s take a closer look at the differences between the two.

AWS VPC Peering vs Transit Gateway

by Valts Ausmanis · August 22, 2024

Connecting two or more VPCs to route traffic privately between them is widely used in different architectures and solutions, such as multi-tier applications, hybrid cloud configurations, cross-account connectivity, and data replication. While both VPC Peering and Transit Gateway allow you to connect multiple VPCs, there are significant differences between them in terms of simplicity, flexibility, usage limitations, and associated costs. By understanding these differences, which we will describe in this article, you will be better equipped to choose between VPC Peering and Transit Gateway.

AWS security group and network ACL

by Valts Ausmanis · August 14, 2024

AWS network security is one of the foundations that should be taken seriously, especially when you deploy your AWS resources in Amazon Virtual Private Cloud (VPC). There are two main building blocks that allow you to control access to AWS resources within the VPC - security groups and network access control lists (NACLs). While both play a fundamental role in controlling inbound and outbound traffic to your AWS resources, there are important differences between them. In this article, we will take a closer look at the differences between security groups and network ACLs.

AWS CloudTrail Overview

by Valts Ausmanis · July 18, 2024

AWS Lambda accelerates new application development by allowing product teams to focus on actual business values rather than spending a time maintaining and operating underlying infrastructure. While AWS manages all the foundation services and underlying infrastructure, you are still responsible for the code you write to operate your product’s business logic and configuration of Lambda functions. I have created a useful list of best security practices with practical examples to help you to improve the security of your AWS Lambda functions.

AWS CloudTrail Overview

by Valts Ausmanis · July 12, 2024

Logging user activity and API usage on AWS is a must for any organization. This practice helps meet compliance standards, respond quickly to issues, and keep your AWS accounts secure. Every AWS account has CloudTrail enabled by default, providing management event history for the past 90 days. To maximize the benefits of CloudTrail and enhance your security, it's important to follow some best practices, which we will describe in this article.

AWS config rules every AWS account should have

by Valts Ausmanis · July 5, 2024

Every application that we deploy to AWS is built using multiple AWS services like API Gateway, Lambda, S3, EC2, EKS, VPC, etc. All of these deployed services consist of multiple AWS resources. To ensure that your AWS account is secure and follows to certain security checks, it’s important to track changes of these resources and continuously assess if the resource configuration complies with your ideal security rules. Luckily, we have AWS Config to record changes and assess your AWS resource configurations. In this article, we will look at how to start using AWS Config and set up 15 AWS Config rules that should be considered for any AWS account.

Improve security of your AWS account

by Valts Ausmanis · June 26, 2024

Nowadays, with many AI productivity tools available like GitHub Copilot, AWS CodeWhisperer, and ChatGPT, you can get things done much faster compared to the old days when you had to spend a lot of time googling and searching the web for the right answers and solutions. This definitely helps speed up the development and deployment of new products and features. However, this also introduces new challenges. We tend to not think too much about the underlying details and security-related configurations of our AWS accounts and services. We somehow trust that the default security settings will work for our use case. You would be surprised how many times, when I have done security checks requested by our customers, I have found out that their AWS accounts and services don’t have proper foundational AWS security controls applied. That’s why I suggest anyone who works with AWS cloud to spend a couple of minutes reading this list of ways to improve the security of your AWS accounts.

AWS SAM

by Valts Ausmanis · January 30, 2024

Documenting your cloud infrastructure is as important as actually building it. Because after you have built your cloud infrastructure and services the real work begins. To maintain that everything works properly you have to understand your cloud architecture. To quickly respond to a security event, you have to have latest architecture diagrams and documentation in place. When things go south you don’t have a time to browse through the AWS console to put all the “pieces together” to see the full picture. That’s why properly documenting your AWS infrastructure should be mandatory task for every product team out there.

AWS SAM

by Valts Ausmanis · January 23, 2024

AWS released AWS serverless application model (AWS SAM) in 2016 to improve the way we build and run serverless applications in AWS cloud. Back then it wasn’t the first choice when compared with Serverless Framework. But what about nowadays? AWS SAM has solid CLI with local development functionality, and community support has grown. In this article we will build a serverless application by using AWS SAM and let’s see how this tool now compares with Serverless Framework – most popular tool for building serverless applications for AWS cloud.

Serverless Framework vs AWS CDK

by Valts Ausmanis · January 16, 2024

Nowadays when we talk about building and deploying cloud applications - Infrastructure as code (IaC) term is no stranger to us. Most of the cloud applications are being managed and deployed through the “code” instead of manual changes. In this article we will take a look on two widely used IaC tools: Serverless Framework and Cloud Development Kit (CDK). Both tools are open-source and built with focus to deploy applications on AWS cloud. Based on the Datadog “State of serverless” report – Serverless Framework is the most popular IaC tool used for managing AWS Lambda functions among Datadog customers. But let’s take a step back because most popular doesn’t always mean the best fit for everything and take a look on what it takes to build and deploy serverless application using both of these tools.
