Kubernetes: Weighing Advantages and Disadvantages

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.

Software Engineering Daily Podcast

Large portions of software development budgets are dedicated for testing code. A new component may take weeks to thoroughly test, and even then mistakes happen. If you consider software defects as security issues then the concern goes well beyond an application temporarily crashing. Although even minor bugs can cost companies a lot of time to locate the bug, resolve it, retest it in lower environments, then deploy it back to production.

Cloudera Data Engineering - Integration steps to leverage spark on Kubernetes

Cloudera Data Engineering is a serverless service for Cloudera Data Platform (CDP) that allows you to submit jobs to auto-scaling virtual clusters. CDE enables you to spend more time on your applications, and less time on infrastructure. CDE allows you to create, manage, and schedule Apache Spark jobs without the overhead of creating and maintaining Spark clusters.

Hybrid Cloud: Unlocking App Modernization With Kubernetes

Last month, we were proud to launch our Hitachi Kubernetes Service, a true storage-as-a-service (SaaS) offering to improve the performance and management of multiple Kubernetes environments. By enabling users to manage their clusters simply and securely across any major cloud provider and on premises, Kubernetes can play an instrumental role in businesses’ modernization efforts. It’s for this reason that we are always working to get it on the radar of our existing clients.

Enabling kubectl for CDE

The kubectl tool provides direct administrative access to the Kubernetes cluster underlying a CDE service, which is useful for troubleshooting, among other things. This video will demonstrate how to set up kubectl access. To enable kubectl, we will need a couple of prerequisites. We wiil need the kubeconfig file from the CDE service. We will need to get and authorize the IAM user, and then need to make sure that everything is set up correctly, both for kubectl and some other tools like k9s.

Lessons Learned When Building A Kubernetes Operator

As we see more customers adopting Rookout for debugging cloud-native applications, we are not surprised to learn that a significant number of them work in a microservice environment. In the most common case among these customers, each service has its own code repository maintained by the team who develops the service.

Optimizing the Docker Container Image for C++ Microservices

In previous posts, we covered the basics of a C++ Microservices deployment including: With those basics in place, this blog will focus on optimization of the container in a C++ Microservices deployment. We'll examine how to structure the Dockerfile and the resulting Docker image to reduce the number of layers and disk space used.
