kong vs istio
Istio is a configurable, open source service-mesh layer that connects, monitors, and secures the containers in a Kubernetes cluster. A service mesh can standardize and automate inter-service communication. The control planes are pods that also run in the Kubernetes cluster, allowing for better resilience in the event that there is a failure of a single pod in any part of the service mesh. Kong powers reliable digital connections across APIs, hybrid and multi-cloud environments. From an Operations point of view, Service Mesh is useful for any type of microservices architecture since it helps you control traffic, security, permissions, and observability.
To expose your services to the world, we will deploy Kong as the north-south traffic gateway. The identity service, combined with encryption, ensures that no unauthorized user can fake—or "spoof"—a service call. Istio uses a version of Envoy, though heavily extended, to perform the monitoring, management, and logging.
The Envoy sidecar will load balance the traffic to three different review pods that contain different versions, giving us the ability to A/B test our changes. When he confirmed that the same issue appeared on the latest version of Kong but not…, Why Tracing? It does that in a much more graceful and scalable way compared to what would otherwise require a lot of manual, error-prone work and operational burden that is not sustainable in the long-run. You should not be using port-forward for regular operations in a production system. We have one last step for folks who would like a visualize representation. Istio has separated its data and control planes by using a sidecar loaded proxy which caches information so that it does not need to go back to the control plane for every call. To do so, run: Having a namespace labeled istio-injection=enabled is necessary. One possible alternative to using Istio would be to deploy Envoy into the Kubernetes cluster directly and write management code. Linkerd is unique in that it is part of the Cloud Native Foundation (CNCF), which is the organization responsible for Kubernetes. However, replacing one service mesh with another is complex, particularly when you want to standardize on the service mesh as a solution to scale across all your services. For local development, Minikube is a popular option if you have enough RAM to allocate to the Minikube virtual machine.
You can either download it via the.
The first service is a hosted webpage: . Linkerd is arguably the second most popular service mesh on Kubernetes and, due to its rewrite in v2, its architecture mirrors Istio’s closely, with an initial focus on simplicity instead of flexibility.
Because the interface for Istio is essentially the same as Kubernetes, managing it takes almost no additional work. To create the necessary RBAC rules for Istio, the current user requires admin permissions: Now, if you get your nodes via kubectl, you should see all 4 nodes that you created on your cluster: To start, you will need to download Istio.
If you want to learn more about Kong and all its various features, check out the documentation page here. In this tech brief, you’ll learn how to be successful with a service mesh: Read more: Best Practices for Selecting and Implementing Your Service Mesh. Kong’s, is one of many plugins that you can use to extend the functionality of your gateway. Istio's instrumentation can manage and visualize the health of applications, providing more insight than just the general monitoring of cluster and nodes that Kubernetes provides.
Here are the necessary steps to follow along: You will need to create a Google Cloud Platform (GCP) account. How difficult is it to install, configure and operate, Service Meshes in Multi-Cloud Environment, Start your service mesh journey early to allow your service mesh knowledge to grow organically as your microservices landscape evolves, grows, and matures, Avoid common design and implementation pitfalls due to lack of knowledge, Leverage your service mesh as the mission control of your multi- cloud microservices landscape. For a managed experience of consuming Istio at scale, stay tuned for when we announce our Managed Istio solution, as part of our Kubernetes managed apps!
Accelerate your journey into microservices. , which includes the gcloud CLI. Kong includes a plugin system that extends the features to beyond what a normal Ingress would do.
Like the suburbs around a city, the number of small services that are deployed seems to expand exponentially. A sidecar is a new container, inside the pod, that routes and observes communications traffic between services and containers. By default, Kubernetes provides round-robin load balancing. This should match the directory created during our Istio installation procedure. This is Istio’s Bookinfo Application diagram with Kong acting as the Ingress point: You can follow the link above to get more details about the application. To start the installation process, make sure you are in the Istio installation directory.
From an Operations point of view, …
Before diving into the various Ingress Controllers, let’s quickly review what a Kubernetes Ingress is and what an Ingress Controller does. As the number of services increases, the number of potential ways to communicate increases exponentially. To do so, you first have to have an existing project. These key capabilities provide operational control and observability into the behavior of the entire network of distributed microservices that make up a complex cloud-native application. The thing that is most crucial to understand about microservices is that they are heavily reliant on the network. A microservices architecture might have a dozen different nodes, each representing different microservices. It helps you control traffic, security, permissions, and observability in complex microservices landscapes. Administrators can also use labels to indicate what type of service to connect to and build rules based on headers. Istio also provides two other dashboards: Kiali and Jaeger. In this example, we’ve traced the product page.
The solution’s architecture has implications on operation overhead.
Istio comes with many dashboards (out of the box) to monitor system health and performance.
This profile installs an Istio sidecar on all newly deployed workloads. A complex dependency chain might have 10 or 12 service calls. . to expose the necessary services. We have a rate-limit set for this service. In that case, the software might build an entirely new version of the application in production without sending production users to it. Declarative configuration allows you to specify the desired system state through a YAML or JSON file instead of a sequence of API calls. The most common way to do this in a cluster is to use the sidecar pattern.
To view the product page service’s GUI, go to http://$KONG_IP/productpage. Called "sidecar" containers, these act as a "person in the middle," directing traffic and monitoring the interactions between components. In this article, you’ll see how easy it is to expose an application publicly using Kubernetes Services. Let’s export that to an environment variable so we can easily reference it in the remaining steps: Congratulations, you now have a service-mesh up and running with a way to access it securely! Enough talk though, let’s deploy our gateway using: To check if the Kong service and pods are up and running, run: When the gateway is running correctly, you will see an EXTERNAL-IP on the Kong service. For a minimalistic approach supporting just Kubernetes, Linkerd may be the best choice. Due to burdensome hardware requirements, I will be using Google Kubernetes Engine (GKE) instead of Minikube. By default, Kubernetes allows every pod to send traffic to every other pod.
It will consist of 4 nodes, and sit on the us-east1-b compute zone. In order to give you better service we use cookies. Istio users can either run new and different types of YAML files with kubectl or use the new, optional, ioctl command. We will use this to create the Kubernetes cluster. If you decided to install your cluster locally on Minikube or use another cloud provider’s Kubernetes platform, be sure you install Istio with the.
The pay_claim service at an insurance company calls the deductible_amt service, which calls the is_member_covered service, and so on. To do so, you have to use.
Istio. Although, when you think about it, this is essentially rewriting what Istio is, with all the associated costs and bugs of a custom development project. Kubernetes networking can be noisy, tedious, and complex.
If you're interested in exploring Knative, see "Knative: An Essential Guide.
At the same time, with Istio's access controls, dashboards, and debugging tools described below, you can easily add a plugin at the command line, rather than go to a web page. You can use it to track service requests, drill into details, or even export the service request history as a JSON to query and format in your own way.
These can measure CPU and memory utilization, traffic demand, the number of 400 and 500 errors, time to serve requests, and more. All services should have a cluster-ip except for the jaeger-agent: That’s it for part 1! To list all your existing projects and to ensure that that “kong-istio-demo-project” project was created successfully, type the following command: With a project created, you can now create a cluster of running containers on GKE: (Optional step) – If you are unsure which zone to use when you create your cluster, run the following command to list out all the compute zones and pick one. That is, with Istio, it will take less effort to manage a wider group of services. If a service is overloaded or down, additional requests will fail while continuing to overload the system. My favorite feature is the graphs that allow me to visualize the topology of the service mesh.
to lightly protect this service. A node consists of one or more containers, along with file systems or other components. For local development, Minikube is a popular option if you have enough RAM to allocate to the Minikube virtual machine.
Every pod needs to be tracked, and Istio needs to aggregate and provide information about all of the pods. AAA provides security and operations professionals the tools they need to monitor, with less overhead. or run the following command with a specific version number: //git.io/getLatestIstio | ISTIO_VERSION=1.2.4 sh -, As you can see in the screenshot above, the Istio directory’s bin has been added to my path.
Istio is quickly becoming the standard for service mesh on Kubernetes. A service mesh standardizes and automates security, service discovery and traffic routing, load balancing, service failure recovery, and observability. To expose your services to the world, we will deploy Kong as the north-south traffic gateway. If you need to catch up and install Istio, follow our.
This exponential growth in microservices creates challenges around figuring out how to enforce and standardize things like routing between multiple services/versions, authentication and authorization, encryption, and load balancing within a Kubernetes cluster. Therefore, it is important to only use this on a fresh Kubernetes cluster where all workloads will be Istio-enabled. Here is the gist of the YAML file we will use to deploy and configure Kong: As shown in the ConfigMap, we will be configuring Kong with two services.
To do so, you have to use kubectl apply to install all the Istio Custom Resource Definitions (CRDs) defined in the istio-1.2.4/install/kubernetes/helm/istio-init/files directory. 1. Kiali is a console that offers observability and service mesh configuration capabilities. Notable Improvements in 0.7.1 Official Helm Charts now…, Some weeks ago, a Kong user reported an error they had on ARM64 servers. We have a rate-limit set for this service. Istio was the first to include additional features that developers really wanted, like deep-dive analytics.
