.png?width=1200&height=675&name=image%20(1).png)
We recently announced the general availability of Red Hat Ansible Automation Platform 2.4, This blog outlines the features of execution environment builder (ansible-builder) 3.0 that was included with this latest release.
With the introduction of Ansible Automation Platform 2, we introduced the concept of automation execution environments. A key part of enabling our customers to create, manage, and scale their automation, they are portable Ansible runtime environments which enable us to truly decouple the control and execution planes in Ansible Automation Platform. Automation execution environments replace the traditional virtual environments in Ansible Tower by providing a powerful dependency management solution. Customers can also improve their automation run efficiency, as they are lightweight Ansible runtime environments.
In general, an automation execution environment includes:
- Base UBI 8/9 image.
- A version of Python
- A version of ansible-core
- Python modules/dependencies
- Ansible Content Collections (optional)
The execution environment builder tool was built to aid in the creation of execution environments for Ansible customers and users. It provides a definition schema that is based on the above execution environment requirements.
Ansible-builder 3.0 enhancements
ansible-builder version 3.0 introduces some major changes in the definition schema to help customers Continue reading
The Arrival of Open AI Networking
Recently I attended the 50th golden anniversary of Ethernet at the Computer History Museum. It was a reminder of how familiar and widely deployed Ethernet is and how it has evolved by orders of magnitude. Since the 1970s, it has progressed from a shared collision network at 2.95 megabits in the file/print/share era to the promise of Terabit Ethernet switching in the AI/ML era. Legacy Ethernot* alternatives such as Token Ring, FDDI, and ATM generally get subsumed by Ethernet. I believe history is going to repeat itself for AI networks.
AWS Advanced Networking Speciality 1.3:Considerations for encryption and authentication with load balancers (for example, TLStermination, TLS passthrough)

Data Protection in ELB
AWS Shared-Responsibility Model defines how data protection applies in ELBs. It boils down to AWS protecting global infrastructure while the service consumer is more responsible for preserving the content and control over the hosted content.
Few important suggestions for accessing/Securing
- MFA for accounts
- TLS 1.2 or TLS 1.3 for AWS resource communication
- Logging with AWS CloudTrail
- Amazon Macie — Discovering and securing sensitive data in S3
- FIP140–2 — Fips Endpoint
Encryption
Encryption at rest: Server-side encryption for S3 (SSE-S3) is used for ELB access logs. ELB automatically encrypts each log file before storing it in the S3 bucket and decrypts the access log files when you access them. Each log file is encrypted with a unique key, which is encrypted with a master key that is regularly rotated.
Encryption in Transit:
HTTPS/TLS traffic can be terminated at the ELB. ELB can encrypt and decrypt the traffic instead of additional EC2 instances or current EC2 backend instances doing this TLS termination. Using ACM (AWS Certificate Continue reading
AWS Advanced Networking Speciality 1.3: AWS Load Balancer Controller for Kubernetes clusters
List of blogs on AWS Advanced Networking Speciality Exam — https://medium.com/@raaki-88/list/aws-advanced-network-speciality-24009c3d8474
Before understanding LoadBalancer Service, it’s worth understanding a few things about NodePort service.
NodePort Service :
NodePort service opens a port on each node. External agents can connect directly to the node on the NodePort. If not mentioned, a randomly chosen service is picked up for NodePort. LoadBalancing here is managed by front-end service, which listens to a port and load balances across the Pods, which responds to service requests.
LoadBalancer Service:
Like NodePort Service, the LoadBalancer service extends the functionality by adding a load balancer in front of all the nodes. Kubernetes requests ELB and registers all the nodes. It’s worth noting that Load Balancer will not detect where the pods are running. Worker nodes are added as backend instances in the load balancer. The classic-load balancer is the default LB the service chooses and can be changed to NLB(Network Load Balancer). CLB routes the requests to Front-end, then to internal service ports Continue reading

Implementing workload-centric Web Application Firewall (WAF) using Calico
Microservices security is a growing concern for businesses in the face of increasing cyber threats. With application layer attacks being a leading cause of breaches, it’s more important than ever to safeguard the HTTP-based communication between microservices within a Kubernetes cluster. Traditional web application firewalls (WAFs) are not designed to address this specific challenge, but Calico WAF offers a unique solution.
What is a workload-centric WAF?
Calico WAF, a workload-centric web application firewall, brings a fresh, cloud-native approach to securing microservices communication. Unlike traditional WAFs deployed at the edge of a Kubernetes cluster, Calico WAF focuses on protecting the intra-cluster traffic and applies zero-trust rules specifically designed for microservices within your cluster.
This innovative solution defends against common HTTP-layer attacks, such as server-side request forgery (SSRF), improper HTTP header type, occurring within the cluster. It seamlessly integrates with Calico Cloud network policies, enabling the enforcement of security controls at the host level for selected pods.
Calico WAF ensures the secure communication between microservices within your Kubernetes cluster, reducing the risk of vulnerabilities and threats. By adopting Calico WAF, businesses can confidently fortify the HTTP-based communication channels within their microservices architecture. This comprehensive approach enhances the overall security posture of Continue reading

The Era of Multi-Cloud is Here: Here’s How to Get the Most Out of It
Enterprises need to optimize their multi-cloud investments to enjoy the benefits of things like lower cost and better performance.DDoS threat report for 2023 Q2
Welcome to the second DDoS threat report of 2023. DDoS attacks, or distributed denial-of-service attacks, are a type of cyber attack that aims to disrupt websites (and other types of Internet properties) to make them unavailable for legitimate users by overwhelming them with more traffic than they can handle — similar to a driver stuck in a traffic jam on the way to the grocery store.
We see a lot of DDoS attacks of all types and sizes and our network is one of the largest in the world spanning more than 300 cities in over 100 countries. Through this network we serve over 63 million HTTP requests per second at peak and over 2 billion DNS queries every day. This colossal amount of data gives us a unique vantage point to provide the community access to insightful DDoS trends.
For our regular readers, you might notice a change in the layout of this report. We used to follow a set pattern to share our insights and trends about DDoS attacks. But with the landscape of DDoS threats changing as DDoS attacks have become more powerful and sophisticated, we felt it's time for a change in how we present Continue reading
Informe sobre las amenazas DDoS en el 2º trimestre de 2023
Te damos la bienvenida al segundo informe sobre amenazas DDoS de 2023. Los ataques DDoS, o ataques de denegación de servicio distribuido, son un tipo de ciberataque cuyo objetivo es sobrecargar de tráfico sitios web (y otros tipos de propiedades de Internet) para interrumpir el funcionamiento normal y que los usuarios legítimos no puedan acceder a ellos, lo mismo que cuando un conductor está atrapado en un atasco de camino al supermercado.
Observamos muchos ataques DDoS de diferentes tipos y tamaños, y nuestra red es una de las mayores del mundo, ya que abarca más de 300 ciudades en más de 100 países. A través de esta red atendemos más de 63 millones de solicitudes HTTP por segundo durante picos de tráfico y más de 2 billones de consultas de DNS cada día. Esta ingente cantidad de datos nos ofrece una perspectiva privilegiada para dar a conocer a la comunidad tendencias reveladoras sobre los ataques DDoS.
Nuestros lectores habituales quizá noten un cambio en el diseño de este informe. Solíamos seguir un patrón fijo para compartir nuestras percepciones y tendencias sobre los ataques DDoS. Sin embargo, creemos que ha llegado el momento de cambiar la forma de presentar nuestras Continue reading
