Reading Time: 4 minutes Introduction Zone Redundant Load Balancers are used in availability zone scenarios where we require that the application is not affected in response due to a zone failure. You may usually find 3 Availability zones in a region. As shown in the diagram, we will use the following setup to configure our Zone redundant load balancer. Step 1: Creating a Virtual Network First, we create a Continue Reading
Reading Time: 4 minutes Introduction The Internal load balancer manages load for a private network with any inbound access from the public platform. As in the diagram below, the primary load balancer managing load from the internet is a public-type load balancer. But, the VMs communication to storage or database is managed through a type-internal load balancer. Internal Load Balancer Setup Let us see our setup which we will Continue Reading
Reading Time: 4 minutes Azure Event Hub Setup: We will create an Eventhub namespace, an event hub and a storage account on Azure Cloud. And then, we will integrate them using a connection string. Before we create other resources, we will create a common resource group: rg-eventhub. Step 1: Event Hub Namespace Now we create an event hub namespace with the following configurations. And then, verify and Create. Step Continue Reading

Reading Time: 4 minutes Introduction As we gave a basic introduction to Docker in this blog. Docker provides OS independent containers that run in an isolated environment. Docker networking enables these containers to communicate with other containers and other required places like the internet to gain the updates of applications. With the understanding of networking in Docker, we can create custom networks for our containers as per the requirements. Continue Reading

Currently, in a gsuite email id, the 2 Factor Authentication blocks unauthorized and less secure app access. eg. when we need to send notifications for alerts using Prometheus. We will see two ways to overcome it. Gmail Notification Method 1: Less Secure App Access If you visit https://myaccount.google.com/lesssecureapps you will see it is Continue Reading
Reading Time: 5 minutes Introduction This blog is similar to previous blog where we explored service mesh configuration using User Interface. Here, we will see how istio is able to manage certification for cluster. Since it was a long topic we will cover the external certification addition part in Part 2. Terms to be known Istiod works as both RA and CA. Istio manages certificates by istiod itself. Installation Continue Reading
Reading Time: 4 minutes Introduction In our old blog, we explored service mesh configuration using User Interface. Here, we will see how istio is able to manage certification for cluster. This blog covers left work of Part -1 where we explored on how istio itself creates certificates for cluster and manage certificates for cluster. We will see various ways the istio can add external certifications. Terms to be known Continue Reading
Reading Time: 6 minutes Introduction This blog is development to the previous blog “Istio and Kubernetes Relationship”. That blog was about Service Mesh and Use of Istio with Kubernetes. In last part where we were able to monitor the flow of traffic using Kiali and Istio on the Kubernetes Cluster. Now we apply every feature of service mesh as defined in the blog “A quick guide to service mesh” Continue Reading

Reading Time: 5 minutes Introduction Dagger is a devkit used in CICD using BuildKit and CUE for platform independent pipeline creation. The language CUE stands for Configure,Unify and Execute. It is a logical configuration language. This means it can create template with scripting as well. We have explore Dagger in this blog. We will see various feature that are useful for Dagger environment in CUE. We will using CUE Continue Reading
