HashiCorp today announced the general availability of its Consul service mesh as a managed service on the HashiCorp Cloud Platform (HCP) along with a beta release of a managed instance of HCP Vault, a secrets management platform, on HCP.
HCP is currently hosted on the Amazon Web Services (AWS) platform, on which the company is making available its complete portfolio as a managed service. In the longer term, HashiCorp plans to make its managed services available on all the major cloud platforms.
Chris Kent, director of product marketing for HashiCorp, said despite the growing number of open source service mesh alternatives, many organizations would prefer to employ a service mesh provided by a single vendor that they didn’t have to provision and maintain. HashiCorp’s Consul service mesh provides a lightweight alternative that enables service-to-service networking and security via connection authorization and encryption and spans both Kubernetes clusters and virtual machine platforms using the mutual Transport Layer Security (mTLS) protocol.
Applications can then employ sidecar proxies in a service mesh configuration to establish TLS connections for inbound and outbound connections without ever having to directly interface with Consul itself.
HashiCorp is making the case for Consul at a time when internecine warfare is raging between proponents of open source service mesh platforms such as Istio, Linkerd and Kuma. The Consul service mesh provides an alternative that is simpler for developers to incorporate across both microservices-based applications running on a Kubernetes cluster and legacy monolithic applications running on virtual machines, Kent said. In contrast, Istio and Linkerd are designed solely for use in Kubernetes environments.
It’s still the early days of service mesh adoption. In addition to simplifying application traffic routing between services, one of the other benefits of service mesh is that it provides a layer of abstraction above lower-level network application programming interfaces (APIs) and protocols that is more accessible to developers. As developers become more familiar with service meshes, the ability to programmatically include network and security operations within a DevOps workflow will grow. HashiCorp is collectively positioning Consul and Vault as foundational components for creating a zero-trust architecture.
In the meantime, each IT organization will need to determine which type of service mesh makes the most sense for their environment. In many cases, organizations may find themselves employing multiple service meshes to address different use cases. Regardless of which they choose, service meshes will soon become a permanent fixture in the proverbial solar system around which IT services revolve.
HashiCorp claims that more than 2,000 organizations signed up to participate in the HCP Consul and HCP Vault beta programs. That level of interest suggests interest is growing in consuming IT as a service rather than as a platform that requires deployment by an internal IT team. It remains to be seen the degree to which organizations will prefer to consume those services directly from a vendor, versus a cloud service provider or third-party IT services provider.
