At PrestoCon Day 2025, we unveiled the Presto Sidecar, a powerful enhancement for Presto C++ (Velox) clusters that transforms how coordinators interact with native workers. This innovation removes long-standing blind spots in query planning by giving the coordinator real-time visibility into native worker capabilities – such as supported functions, data types, session properties, and plan...

Die iPad Pros sind mittlerweile leistungsfähiger als manches Notebook. Das bedeutet auch dass Ihr sie unter macOS als vollwertigen, kabellosen Monitor am Macbook nutzen könnt! Die von Apple SideCar genannte Funktionalität ist nicht neu und existiert schon seit einigen Jahren. Allerdings war sie am Anfang eher Spielerei und kaum für…| Jörg Schieb | Digital und KI
There are 2 deployment modes for Istio: ambient mode and sidecar mode. The former is still on the way, the latter is the classic one. Therefore, the coexistence of ambient mode and sidecar mode should be a normal deployment form and the reason why this blog may be helpful for Istio users. Background In the architecture of modern microservices, communication and management among services is critical. To address the challenge, Istio emerged as a service mesh technology. It provides traffic cont...| Istio Blog
Cryptographic operations are among the most compute-intensive and critical operations when it comes to secured connections. Istio uses Envoy as the “gateways/sidecar” to handle secure connections and intercept the traffic. Depending upon use cases, when an ingress gateway must handle a large number of incoming TLS and secured service-to-service connections through sidecar proxies, the load on Envoy increases. The potential performance depends on many factors, such as size of the cpuset on...| Istio Blog
DNS resolution is a vital component of any application infrastructure on Kubernetes. When your application code attempts to access another service in the Kubernetes cluster or even a service on the internet, it has to first lookup the IP address corresponding to the hostname of the service, before initiating a connection to the service. This name lookup process is often referred to as service discovery. In Kubernetes, the cluster DNS server, be it kube-dns or CoreDNS, resolves the service’s...| Istio Blog
MOSN (Modular Open Smart Network) is a network proxy server written in Go. It was built at Ant Group as a sidecar/API Gateway/cloud-native Ingress/Layer 4 or Layer 7 load balancer etc. Over time, we’ve added extra features, like a multi-protocol framework, multi-process plug-in mechanism, a DSL, and support for the xDS APIs. Supporting xDS means we are now able to use MOSN as the network proxy for Istio. This configuration is not supported by the Istio project; for help, please see Learn Mo...| Istio Blog
Istio sidecars obtain their certificates using the secret discovery service. A service in the service mesh may not need (or want) an Envoy sidecar to handle its traffic. In this case, the service will need to obtain a certificate itself if it wants to connect to other TLS or mutual TLS secured services. For a service with no need of a sidecar to manage its traffic, a sidecar can nevertheless still be deployed only to provision the private key and certificates through the CSR flow from the CA ...| Istio Blog
Nous voici en Ouzbékistan, dernier « nouveau » pays de notre périple. Et oui, nous sommes déjà un peu sur le chemin du retour. Bon, alors, qu’y a-t-il à découvrir dans cet énième pays en -stan ?

The secret of Istio’s abilities in traffic management, security, observability and policy is all in the Envoy proxy. Istio uses Envoy as the “sidecar” to intercept service traffic, with the kernel’s netfilter packet filter functionality configured by iptables. There are shortcomings in using iptables to perform this interception. Since netfilter is a highly versatile tool for filtering packets, several routing rules and data filtering processes are applied before reaching the destinat...| Istio Blog
As users move their services to run in the Istio service mesh, they are often surprised that the control plane watches and processes all of the Kubernetes resources, from all namespaces in the cluster, by default. This can be an issue for very large clusters with lots of namespaces and deployments, or even for a moderately sized cluster with rapidly churning resources (for example, Spark jobs). Both in the community as well as for our large-scale customers at Solo.io, we need a way to dynamic...| Istio Blog
