Implementing SAML federation for Amazon OpenSearch Service with KeyCloak

Welcome back to our series on implementing SAML Federation for Amazon OpenSearch Service. In our previous post, we explored setting up SAML Federation using OneLogin. Today, we’ll focus on another popular identity provider - Keycloak. Keycloak is an open-source Identity and Access Management solution, ideal for modern applications and services. We’ll guide you through integrating Keycloak with Amazon OpenSearch Service to implement SAML Federation.

Enhancing German Search in Amazon OpenSearch Service

Amazon OpenSearch Service, utilizing the robust OpenSearch framework, excels in search and analytics due to its remarkable speed and efficiency. Despite its strengths, the service’s default configurations might not be fully tailored to address the distinct linguistic challenges encountered in specific languages. Take German, for example, known for its compound words like “Lebensversicherungsgesellschaft” (life insurance company). Standard tokenization in search technologies treats these compounds as single units, leading to less optimal search results. For improved accuracy, it’s important to index the components of these compounds separately – “Leben” (life), “Versicherung” (insurance), and “Gesellschaft” (company). This approach ensures more precise and effective search outcomes, particularly in languages like German with many compound words.

Centralized traffic filtering using AWS Network Firewall

In the process of constructing your Hybrid Hub and Spoke Network within the Cloud, which includes the integration of On-Premises networks and allows internet-based access, the implementation of a network firewall is essential for robust security. This security measure involves thorough traffic analysis and filtering between the entities to safeguard against both internal and external cyber threats and exploits. By actively monitoring and inspecting the flow of traffic, a network firewall plays a crucial role in identifying and blocking vulnerability exploits and unauthorized access attempts. Within the AWS ecosystem, the AWS Network Firewall is a service that is often used for achieving a high level of network security. As a stateful and fully managed network firewall, it includes intrusion detection and prevention capabilities, offering comprehensive protection for VPC-based network traffic. This blog post aims to guide you through the process of integrating the AWS Network Firewall into your hybrid AWS Hub and Spoke network. By doing so, you can effectively analyze, monitor, and filter both incoming and outgoing network traffic among all involved parties, thereby enhancing the overall security of your infrastructure layer.

Harnessing the Power of Serverless PHP with Laravel Vapor

I need to start this blog post with a confession. But only if you promise to not tell anything to my tecRacer colleagues, deal? So, I built a monolith. And I loved it. And you will likely love it too if you decide to try out Laravel. Luckily, there is a service called Vapor that will let you deploy your Laravel project on serverless AWS infrastructure. That means I can continue to enjoy the top-notch developer experience of Laravel while also getting all the benefits of serverless technologies (plus, I can maintain a healthy relationship with my colleagues 🎉). But let’s start at the beginning.

Build Golden AMIs with Packer and AWS CodePipeline

When leveraging AWS services such as EC2, ECS, or EKS, achieving standardized and automated image creation and configuration is essential for securely managing workloads at scale. The concept of a Golden AMI is often used in this context. Golden AMIs represent pre-configured, hardened and thoroughly tested machine images that encompass a fully configured operating system, essential software packages, and customizations tailored for specific workload. It is also strongly recommended to conduct comprehensive security scans during the image creation process to mitigate the risk of vulnerabilities. By adopting Golden AMIs, you can ensure consitent configuration across different environments, leading to decreased setup and deployment times, fewer configuration errors, and a diminished risk of security breaches. In this blog post, I would like to demonstrate how you can leverage AWS CodePipeline and AWS Stepfunctions, along with Terraform and Packer, to establish a fully automated pipeline for creating Golden AMIs.

SAP HANA High Availability on AWS - How tecRacer helped secure cash register operations for Germany's leading department store chain

Galeria Karstadt Kaufhof and tecRacer have been collaborating on developing Galeria’s Cloud Platform for many years with tecRacer as their Go-To Partner for everything related to AWS. The work we have been doing ranges from designing, setting up and operating their landing zone and network infrastructure, managing platform security and cost optimizations all the way to deploying complex system architectures such as Kubernetes. Most notably, we have been one of their trusted partners when it comes to their SAP infrastructure on AWS and have supported in many successful SAP system deployments.

Assigning EKS Namespaces to Node Groups

In AWS EKS clusters, there are a couple of use cases for which all pods of a namespace should be automatically scheduled to specific nodes in Kubernetes, including: Clear allocation of data plane infrastructure (and costs) to teams in large organizations, Running critical workloads on on-demand nodes and not on spot nodes, or Using specific hardware, such as GPU, only by workloads that actually require it. In this post, we will explore how to facilitate that in EKS.

Hybrid DNS resolution using Route 53 Endpoints

When implementing a hybrid cloud solution and connecting your AWS VPCs with corporate data centers, setting up proper DNS resolution across the whole network is an important step to ensure full integration and functionality. In order to accomplish this task, Route53 Inbound and Outbound endpoints can be used. In combination with forwarding rules, they allow you to forward DNS traffic between your AWS VPC and on-premises data centers. In this blog post, I would like to show you how you can leverage Route53 endpoints in combination with Terraform to establish seamless DNS query resolution across your entire hybrid network.
