Secure container orchestration at the edge

May 4, 2021 By Canonical In Canonical
The cloud-native way of building software allows for consistency across developer environments and massive scalability of application deployments. Both these attributes are useful for edge, but create new challenges related to security and resilience. Watch this demo to see how Canonical’s modular technology stack addresses these challenges by using well-known cloud primitives.

AWS Fargate runtime security - Implementing File Integrity Monitoring with Sysdig

May 4, 2021 By Sysdig In Sysdig
Thanks to serverless you can focus on your apps, instead of your infrastructure. Take AWS Fargate as an example. A service where you can deploy containers as Tasks, without worrying what physical machine they run on. However, without access to the host How can you detect suspicious activity? Like, file changes on your Fargate tasks? Sysdig provides runtime detection and response to secure Fargate serverless containers.

Dynamic Service Graph | Tigera - Long

May 4, 2021 By Tigera In Tigera
Downtime is expensive and applications are a challenge to troubleshoot across a dynamic, distributed environment consisting of Kubernetes clusters. While development teams and service owners typically understand the microservices they are deploying, it’s often difficult to get a complete, shared view of dependencies and how all the services are communicating with each other across a cluster. Limited observability makes it extremely difficult to troubleshoot end-to-end connectivity issues which can impact application deployment.

Application Layer Observability | Tigera - Long

May 4, 2021 By Tigera In Tigera
The majority of operational problems inherent to deploying microservices in a distributed architecture are linked to two areas: networking and observability. At the application layer (Layer 7), the need to understand all aspects associated with service-to-service communication within the cluster becomes paramount. Service-to-service network traffic at this layer is often using HTTP. DevOps teams struggle with these questions: Where is monitoring needed? How can I understand the impact of issues and effectively troubleshoot? And how can I effectively protect application-layer data?

DNS Dashboard | Tigera - Long

May 4, 2021 By Tigera In Tigera
While it’s an essential part of Kubernetes, DNS is also a common source of outages and issues in Kubernetes clusters. Debugging and troubleshooting DNS issues in Kubernetes environments is not a trivial task given the limited amount of information Kubernetes provides for DNS queries. The DNS Dashboard in Calico Enterprise and Calico CLoud helps Kubernetes teams more quickly confirm or eliminate DNS as the root cause for microservice and application connectivity issues.

Kubernetes: Weighing Advantages and Disadvantages

May 4, 2021 By Kumar Harsh In Scout

Kubernetes is one of the current leading technologies. Its adoption has seen tremendous growth in the past few years. The concept of containers is a paradigm that appears to be the predominant medium of software development and deployment in the coming future. Containers help maintain consistency across various platforms, as they pack an application with its dependencies to help move it from one platform to another.

Guide to using Docker for your CI/CD pipelines

Apr 30, 2021 By Ron Powell In CircleCI

Docker is a platform for developers and sysadmins to develop, deploy, and run applications using containers. Docker is also referred to as an application packaging tool. This means that enabled applications can be configured and packaged into a Docker image that can be used to spawn Docker containers that run instances of the application. It provides many benefits including runtime environment isolation, consistency via code, and portability.
