An Introduction to ISTIO Service Mesh & its Architecture!

ISTIO has become a popular choice for service mesh among enterprises these days, allowing IT teams to add capabilities of observability, traffic management, and security to the apps. Here’s more on ISTIO and its architecture. Read further to know more!

What is ISTIO?

ISTIO Service Mesh is a configurable, open-source service-mesh layer that provides a way to control how microservices share data with one another. It offers a transparent and language-independent way to flexibly and easily automate the network functions within an application.

ISTIO allows IT teams to add capabilities of observability, traffic management, and security to the applications, without the need to add these to the original code. This frees the developers from the pains of writing codes for networking and security from scratch.

Moreover, Istio enables organizations to secure, connect, and monitor microservices, so they can modernize their enterprise applications at a faster pace and securely. This is why ISTIO installation on Kubernetes is being widely adopted by enterprises, both big and small, as the perfect solution to manage different microservices that together build a cloud-native application. ISTIO supports and handles how different parts of a microservices application communicate and share data with one another.

The Benefits of Deploying a Service Mesh ISTIO!

Here are some of the amazing benefits that deploying a Service Mesh can bring to your business. Read this to know more!

Benefits of Deploying a Service Mesh

From start-up to large enterprise, cloud-native to on-premises, organizations of all shapes, sizes, are deploying service mesh in Microservices to improve security, get complete observability, enhance security between service-service communications and to resolve security and networking challenges faced during Kubernetes deployment.

Here, we’ve discussed other such incredible benefits of deploying a Service Mesh. Read to know more!

Know the Role of K8S Service Account in Granting Access

Have you ever wondered that when you access the API Server through kubectl you are authenticated through the API controller, but how will you do the same from the pod side? Here the Service Account role comes into play. As k8s definition itself says “Processes in containers inside pods can also contact the apiserver. When they do, they are authenticated as a particular Service Account (for example, default).”

Things we should know about service Account,

Created in a namespace.
Used to allow processes inside pods, access to the API Server.
Default service account = default (no access to the API server).
Create your own service account.
- Use it in a RoleBinding or ClusterRoleBinding.
- Use the service account secret to obtain the authentication token & CA certificate.

What we will be covering today,

Creating a pod (that gets automatically created in default Service Account)
Will create a Service Account
Creating a deployment that will be using appsa Service Account.

Know How to Use Velero to Backup and Migrate Kubernetes Resources and Persistent Volumes

Introduction

“Murphy’s law doesn’t mean that something bad will happen. It means that whatever can happen, will happen.” This is something related to destiny but we should not totally rely upon it and should be prepared for the worst.
The same philosophy referenced above applies to the tech world too. That’s the reason we should be prepared with our backup options choices possibly, a data set or Kubernetes cluster.

“Always be ready with backup options like Velero for Kubernetes.” Continue reading “Know How to Use Velero to Backup and Migrate Kubernetes Resources and Persistent Volumes”

Top DevSecOps Tools in 2022!

With increasing cyber threats, security has become a major bottleneck in rapid product delivery for enterprises today. Here’s how these top DevSecOps tools can help. Take a look!

DevSecOps is a term that’s short for Development, Security, and Operations. No doubt, this term has become the latest buzzword in the market nowadays. The “DevSecOps” methodology is based and built on the same principles as DevOps, but it is slightly different from it. Here’s how!

The DevSecOps approach incorporates security at all stages of the development workflow. In simpler words, DevSecOps is like DevOps plus security. When we talk about security in DevSecOps, it specifically refers to pipeline security, secure development lifecycle and embedding security policies to mitigate emerging risks, cyber threats & malicious attacks.

There is a wide variety of DevSecOps tools and software to encompass enterprise-grade DevSecOps practices in the software development lifecycle. Here, in this blog, we’ve picked some of the best DevSecOps tools available in the market today.

Let’s take a look at these top DevSecOps tools in 2022, NOW!
