The podcast episode of simplyblock's Cloud Commute features Chris Engelbert interviewing Anders Eknert. They discuss Anders' background and current role at Styra, the company behind the Open Policy Agent (OPA) project. Anders lives and works in Stockholm, Sweden, and has been involved with Styra for about three and a half years. He shares how his previous work led him to OPA due to a need for managing complex authorization requirements across diverse environments.
Styra, founded by the creators of OPA, focuses entirely on the OPA ecosystem. They offer two main products: Styra DAS (Declarative Authorization Service) and an enterprise version of OPA. Styra DAS helps manage OPA at scale, providing a control plane for policy management, lifecycle, and auditing. The enterprise OPA offers enhanced performance, lower memory usage, and direct integrations with data sources.
OPA itself is a policy engine that enables policies as code, allowing for decoupled and centralized policy management. Common use cases include authorization and infrastructure policies, where OPA acts as a layer between services to make policy decisions. The discussion highlights the importance of treating policy like any other code, allowing for testing, reviewing, and versioning.
Chris and Anders also discuss the functionality of OPA from a developer's perspective, explaining how it integrates with services to enforce policies. They touch on the broader benefits of a unified policy management system and how OPA and Styra DAS facilitate this at scale, ensuring consistency and control across complex environments.

In this episode of Cloud Commute, host Chris Engelbert welcomes Abdel Sghiouar, a Kubernetes expert from Google, to discuss various aspects of cloud technology, with a focus on Kubernetes and cloud-native solutions. Abdel, who has been with Google for a decade and specializes in Kubernetes networking, security, and storage, shares insights into the evolution and current state of container technologies.
The conversation begins with Abdel introducing himself and his role at Google, where he works on the Google Kubernetes Engine (GKE). Abdel explains the importance of Kubernetes in modern cloud computing, highlighting its flexibility and scalability, which make it suitable for AI and machine learning workloads that require substantial compute power.
Chris and Abdel delve into the history and impact of containerization, discussing how it evolved from virtual machines to containers and now to Kubernetes. They touch upon the benefits and challenges of adopting Kubernetes and how cloud providers have simplified container services to make them more accessible.
Abdel also talks about his involvement in the Kubernetes community, including his Kubernetes-focused podcast and his newsletter, which covers updates in the Kubernetes ecosystem. He emphasizes the importance of making Kubernetes more user-friendly and less complex, advocating for solutions that abstract away the intricacies of Kubernetes to provide a seamless developer experience.

In this episode, host Chris Engelbert welcomes Moritz Eckert from Edgeless Systems, a company specializing in confidential computing technologies. Moritz shares his background in computer security and his journey into co-founding Edgeless Systems. He dives deep into the concept of confidential computing, explaining its hardware-based approach to encrypt memory at runtime and perform remote attestation to ensure the integrity of the computing environment.
Moritz discusses how Edgeless Systems' flagship product, Constellation, provides an "always encrypted" Kubernetes distribution, allowing data to remain encrypted throughout its lifecycle—from network transit to processing and storage. This ensures maximum security, especially for cloud-native applications, by leveraging hardware features available on modern CPUs.
They explore the practical implications for application developers, emphasizing that the goal is to make the underlying security features invisible to developers, requiring no significant changes to their existing workflows. The conversation also touches on the current landscape of confidential computing hardware, the support from major cloud providers, and the potential for confidential computing in AI and machine learning contexts, particularly with GPUs.

In this episode of our podcast, host Chris Engelbert welcomes Franck Pachot from Yugabyte, a distributed SQL database company. Franck, a developer advocate with extensive experience in databases, discusses the advantages of distributed SQL databases over traditional single-node SQL databases. He explains that Yugabyte offers the robust features of PostgreSQL with the added benefits of horizontal scalability and high availability.
Franck delves into the technical aspects of distributed databases, emphasizing their ability to maintain consistency and provide ACID properties while scaling across multiple nodes. This setup ensures continuous uptime and flexibility to handle high-velocity data without downtime during upgrades or patches. He highlights that Yugabyte is designed for OLTP workloads but can handle various use cases due to its SQL compatibility.
The conversation touches on deployment strategies, with Franck recommending cloud deployment for its elasticity and cost-efficiency, though acknowledging that traditional servers or a hybrid approach can also work. He discusses the practical aspects of migrating between cloud providers seamlessly and the importance of maintaining predictable performance by using similarly sized VMs during such transitions.
