What is k8s StatefulSet?
What is k8s StatefulSet?
StatefulSet is the workload API object used to manage stateful applications. Manages the deployment and scaling of a set of Pods, and provides guarantees about the ordering and uniqueness of these Pods. Like a Deployment, a StatefulSet manages Pods that are based on an identical container spec. Jun 3, 2021
Is Calico a service mesh?
Calico is able address some of the most popular service mesh use cases, without introducing an additional control plane. This makes it operationally a lot simpler to handle, especially if your team has limited resources. Jul 27, 2021
What is calico k8s?
Calico is an open source networking and network security solution for containers, virtual machines, and native host-based workloads. Calico supports a broad range of platforms including Kubernetes, OpenShift, Mirantis Kubernetes Engine (MKE), OpenStack, and bare metal services.
Is API Gateway needed for Kubernetes?
Using an API gateway to handle all inbound and outbound traffic increases the security of the Kubernetes cluster. You can centrally control which users and services have access to each resource through Kubernetes’ native authorization and authentication mechanisms. Nov 2, 2021
What is the difference between API Gateway and ingress controller?
The ingress controller service is set to load balancer so it is accessible from public internet. An api gateway is used for application routing, rate limiting, security, request and response handling and other application related tasks. Nov 27, 2019
What is the difference between Kubernetes and Istio?
Istio’s control plane provides an abstraction layer over the underlying cluster management platform, such as Kubernetes, Mesos, etc. On the other hand, Kubernetes is detailed as “”Manage a cluster of Linux containers as a single system to accelerate Dev and simplify Ops””.
What is Istio ingress Gateway?
Configuring ingress using an Istio gateway An ingress Gateway describes a load balancer operating at the edge of the mesh that receives incoming HTTP/TCP connections. It configures exposed ports, protocols, etc. but, unlike Kubernetes Ingress Resources , does not include any traffic routing configuration.
What does high ingress mean?
Whenever you say Ingress, it means traffic is towards you, depending on the hand you are looking at. When you upload data to the internet its going out of your local network so the traffic is egress based on the LAN’s perspective but not the router, it will treat that data as ingress since is coming towards it.

What is ingress rule?
As a short definition, an Ingress is a rule that charts how a service, walled inside the cluster, can bridge the divide to the outside world where clients can use it. May 6, 2020
What is the difference between ALB and NLB?
Network Load Balancer works at Transport layer (Layer 4 of the OSI model, Connection level). NLB just forward requests whereas ALB examines the contents of the HTTP request header to determine where to route the request. So, application load balancer is performing content based routing.

What is an EC2 in AWS?
Amazon Elastic Compute Cloud (Amazon EC2) provides scalable computing capacity in the Amazon Web Services (AWS) Cloud. Using Amazon EC2 eliminates your need to invest in hardware up front, so you can develop and deploy applications faster.
What is the difference between Load Balancing and elasticity?
Whereas a request to a specific URL backed by a Classic ELB would only enable routing to a particular pool of homogeneous servers, the ALB can route based on the content of the URL, and direct to a specific subgroup of backing servers existing in a heterogeneous collection registered with the load balancer. Mar 28, 2018
What is AWS EKS ingress?
The Ingress resource configures the Application Load Balancer to route HTTP or HTTPS traffic to different pods within your Amazon EKS cluster. You can use AWS WAF to monitor the HTTP or HTTPS requests that are forwarded to the Application Load Balancer. Jun 28, 2021
