Grafana is an open-source visualization tool used to monitor infrastructure in real-time. The visualization of data through graphs helps in log analysis and troubleshooting real-time infra issues. Many companies are implementing Grafana as it can connect with many data sources, like Prometheus, MySQL, InfluxDB, AWS CloudWatch, and others. This flexibility of supporting various data sources […]

Problem Introduction: In Part 1, We have seen how to automate the process of increasing the limits/requests for the pods memory/cpu using the webhook alerts feature of alert manager and webhook triggered pipelines of spinnaker. In Part 2, , it was shown how to use verticalpodautoscaler (VPA) to get the recommendations for pod memory and cpu requests as […]

Problem Introduction: In Part 1, We have seen how to automate the process of increasing the limits/requests for the pods memory/cpu using the webhook alerts feature of alert manager and webhook triggered pipelines of spinnaker. But what value should we patch? How to decide on the optimal values for cpu/memory as these values varies from application […]

Problem Introduction: Kubernetes does a good job in self healing and application recovery from failure. New pods come up in the place of pods that crash. One reason for pods failing in kubernetes cluster is the memory consumed exceeding the limit set. In this case, kubernetes pods are OOM killed ( out of memory) and […]

Many organizations are using a combination of Jenkins and a tool like Ansible, Puppet, Chef, or Salt to automate their CI/CD pipelines but find themselves having to do many steps manually or using a series of scripts that can be hard to maintain. Many organizations manually move software from Development to Staging to Production with time-consuming manual processes. Spinnaker can fully automate these processes. Spinnaker can fully integrate with standard CI/CD tools such as Jenkins, SonarQube, and Artifactory but add a layer of automation to automate software deployments to Development, Staging, and Production, eliminating many manual steps. Spinnaker also automates the creation of Canary Analysis and Blue/Green environments. Many large organizations, including Netflix and Google, use Spinnaker. Spinnaker was developed at Netflix and Google to automate their massive volume of CI/CD pipelines, but both large and smaller organizations can benefit from Spinnaker’s automation.

To fully understand Istio we need to take a detour and learn about Service mesh. Let us do a through recap of what a service mesh is? When infrastructures shifted from monolithic to microservices, containers could bring in consistency and granularity in managing resources. Microservices allowed us to treat one computer as many computers. This […]

Introduction Service mesh is an infrastructure layer built on top of a microservice architecture to provide observability, security, and reliability to applications. It ensures that the communication across containers or pods is secure, fast, and encrypted. Though the communication problems were a by-product of moving away from a monolith architecture, the benefits surpass the challenges […]
