"In that case, they're running one big container and there's no connectivity issue," she said. Sun says that most enterprises typically begin their journey to containers simply to lift and shift legacy monolithic applications to the cloud, and don't really need service meshes.
What is kubernetes service mash code#
I don't want to just protect the edge, I want to be able to do zero trust communication among all my services, and I want keys and certificates to rotate, maybe every 10 days or every 30 days or even every day, and I want that automation consistently.' A service mesh like Istio can solve this really easily, and without requiring any code change on your micro services." "A lot of our users are adopting Istio just because their security team says, 'I want mutual TLS among all my services. "We are perceived to be complex because we're the most feature rich service mesh," said Lin Sun, director of open source at Istio-focused solo.io and a member of the Istio Technical Oversight Committee. Like other "full service" meshes, it works with the open source proxy server Envoy, which is the source of both its rich set of capabilities and its complexity. It's included by default in Red Hat's OpenShift container platform, as well as being the default mesh in both Google's and IBM's clouds.
Those organizations will need to employ a full-featured service mesh like Istio, an open project started by Google, IBM and Lyft, which can handle the traffic from those mixed environments.Īlthough it's considered complex and difficult to master, Istio is the service mesh architecture getting the most attention. Linkerd, which just became a graduated project at Cloud Native Computing Foundation, is considered to be the easiest to use, although it's a rather limited containers-only solution that isn't able to incorporate virtual machines and monolithic legacy apps running on bare metal, which is essential to many – if not most – enterprises. Other open source meshes (besides Linkerd) include, Kuma and Istio. Amazon Web Services, Microsoft Azure and Google Cloud Platform all offer their own branded service mesh architectures, as does VMware with its proprietary Tanzu and Hashicorp with Consul. Since the launch of Linkerd, the service mesh field has become quite crowded. "I think what you'll see instead is a service mesh that spans those environments, where you have this kind of logical application-level connection on top of multiple distinct physical networks." "If you go back a few years, I think everyone thought that SDN technology would result in this virtual network that spanned all these locations, but that's actually really hard for most people to operate," said Jason McGee, VP and CTO at IBM Cloud Platform. Service mesh also makes it easy to consistently deploy Kubernetes in hybrid-cloud environments where IT pros are looking at on-premises data centers, multiple clouds and edge locations as a single infrastructure – something that isn't easy using traditional, software-defined networking technologies.
The purpose of a service mesh is to act as a sort of secondary network that sits between the network and applications – and it performs two big functions: to help services find and connect to each other and to make sure that repeated attempts to connect after a connection failure don't overwhelm the system. What Are Service Mesh Architectures, Anyway? Indeed, it's the added complexity and traffic that serverless functions such as microservices bring into play that makes service mesh architectures attractive, despite the added complexity that they bring to the table. At the same time, they're bringing changes to the ways that enterprises are consuming their infrastructures, which has resulted in the increasing use of managed container services. The current rise of service mesh architectures as part of container platforms is just another example of the transformative – some might say disruptive – effect that container technology has had in the modern data center.Ĭontainers have made it easier for companies to deploy hybrid and multiple cloud solutions.
Although service mesh architectures only came on the scene four years ago with the release of Linkerd, the technology is increasingly being considered as essential for organizations deploying containers, especially in hybrid cloud environments.
