An Introduction to Service Mesh Architecture!

In its 2020 Cloud-Native Survey most recent report, The Cloud Native Computing Foundation (CNCF) found that the use of service mesh in production jumped 50% in the last year.

You can read about Service Mesh, the benefits of deploying a Service Mesh, and ISTIO architecture, here in the given links!
– The Benefits of Deploying a Service Mesh
– An Introduction to ISTIO Service Mesh & its Architecture!

With the popularization of microservices architectures, there has emerged the need of using a Service Mesh. The use of Service mesh in Kubernetes is the most thought-after step to overcome security and networking challenges obstructing Kubernetes deployment and container adoption.

Let’s read and explore more on Service Mesh, its architecture, components and popular solutions for service meshes, here in this article. Here, we’ll know talk about,

Handling Private Affair: A Guide to Secrets Management System

Needless to say an automated system, no matter how big or small, must be designed with scale in mind. We’ll talk about laying foundation for a robust and malleable setup which is a useful read for everyone.

In my experience as DevOps and SRE, I’ve enjoyed quite a lot of things this profession offered. From the satisfaction of fulfilled curiosities to the anxiety of unforeseen mishaps, it delivered one day after the other. The nervousness in the face of new challenges, happiness on receiving appreciation, thrill during troubleshooting, the pride after a successful implementation, and a lot more. But the one I found myself seeking was boredom. Yes, plain old silence where no surprises are met, everything runs exactly as it should and you enjoy listening to dropping pins. This is especially true when the system in question is your own design. There’s no greater sentiment. It is like watching a bird that you’ve freed soar.

BigBulls Game Series- Patching MongoDB using Ansible

MongoDB is the most popular NoSQL and an open-source document-oriented database. The term NoSQL means ‘non-relational’.This simply means mongo does not base on a table-like relational database structure. It is moreover a schemaless database. In Mongo information is stored in JSON-style documents.

Observability for Monitoring Microservices — Top 5 Ways!

Introduction

Knowing what’s running inside the container, how the application and code are performing is critical for tackling important issues. Discussed here are some important Microservices monitoring tools and approaches. Take a look!

With Microservices architecture becoming the de facto standard for web applications now, effective debugging and anomaly detection calls for a system that is observable — which means, the internal state of an application can be inferred by observing and tracking the metrics, traces and logs.

Learn the Hacks for Running Custom Scripts at Spot Termination

Nowadays, it is very common to run applications on Spot instances. In this scenario, where a spot instance could be terminated at any point of time because of AWS pulling back their resource or ASG Scale-In incident, we need to have something in place to handle the termination smoothly so that we can complete our final tasks before the system shutdown. It could be executing some scripts, unmounting some storage device, shipping final log files to S3, or uploading cache data in a centralized server like Redis.
Today, I will attempt to cater to this problem.

First of all, let’s think of trying to run a custom script prior to shutdown in our local system. If everything works fine, the same would be applicable for ec2 spot instances too.
