When you consider software program networking, at its core, it has two primary features: (1) ship site visitors from A to B as shortly and effectively as potential, and (2) transfer site visitors from A to B however NOT to X, Y, or Z. Software program-Outlined Networking (SDN) separates these two features, permitting the {hardware} to carry out the primary job, whereas the second job of community coverage enforcement is carried out in software program.
This easy idea turns into quite a bit trickier although in in the present day’s atmosphere of distributed purposes, digital machines, containers, and cloud belongings. Functions might have little to no perception into the underlying infrastructure, leaving a niche in visibility and safety. So, how does the safety crew guarantee visibility and correct safety controls whereas not hindering networking and utility efficiency? How do you deliver networking and safety nearer collectively so that you simply defend workloads regardless of the place they run?
That’s the place eBPF is available in. It’s an open supply know-how that enables subtle software program packages to program the center of the working system – often called the kernel – with out truly altering the center of the working system. That is extremely highly effective as a result of it unlocks safety, observability, and networking performance on the kernel-level that was not potential earlier than.
At this time, Cisco is worked up to announce our intent to accumulate Isovalent, Inc., based by creators of eBPF and the crew
behind the creation of Cilium and Tetragon, the main cloud native options leveraging eBPF know-how.
Cisco turned an investor in Isovalent as a part of their Collection A funding spherical in 2020. On the time, Cilium was already used for cloud native connectivity and the default in managed Kubernetes choices for a number of main public cloud suppliers together with Google Kubernetes Engine, Google Anthos, and Amazon EKS Wherever.
Cilium gained high-adoption with hyperscalers and cloud suppliers due to its unparalleled visibility into the conduct and communication of cloud native purposes and seamless capacity to outline the coverage of a software-defined community. Since 2020, Isovalent has continued to innovate, not too long ago introducing Cilium Mesh to permit for the straightforward connection of Kubernetes clusters with present infrastructure throughout hybrid clouds, in addition to Tetragon, their open supply safety utility.
Tetragon supplies safety controls to guard workloads as they run by gathering detailed details about the applying’s inner processes and the way they behave on the community. This broad perception supplies the best type of safety for workloads working on any cloud. Tetragon additionally contains necessary compliance functionality and integration with instruments cloud suppliers and enterprises use to observe and remediate safety incidents.
What’s Subsequent
As we glance forward, Cisco is concentrated on serving to prospects handle these visibility and safety challenges by means of the Cisco Safety Cloud, an AI-driven, cloud-delivered, built-in safety platform for organizations of any form and dimension. A reputable hybrid, multicloud community safety functionality is key to easing operational complexity for our prospects. The Cisco Safety Cloud does this by making it simpler to outline and implement insurance policies from a single cloud-delivered console throughout each hybrid and multi-cloud environments.
Cisco is dedicated to Cilium and Tetragon as open supply tasks and intends to create an unbiased advisory board to assist steer Cisco’s contributions to those necessary efforts in a method that’s aligned with the wants of the open supply group. Collectively, Cisco and Isovalent will construct on the ability of Cilium and Tetragon to create multicloud safety and networking capabilities which might be really distinctive, Cisco will proceed providing and enhancing Isovalent Enterprise for Cilium to prospects. Isovalent’s Cilium Mesh enhances Cisco software-defined networking options and collectively would give prospects seamless and safe networking from the department workplace to the info middle, to the general public cloud, utilizing one steady mesh. {Hardware} acceleration of networking features will be sure that the already performing eBPF platform will proceed to steer the business. By leveraging the menace intelligence of Cisco Talos and Cisco’s more and more highly effective safety analytics functionality, Cisco and Isovalent will collectively construct modern safety for any workload on any cloud.
Cisco and Isovalent are excited to drive the following technology of cloud networking and safety innovation based mostly on open supply know-how. We stay up for persevering with to work with CNCF and different open supply communities to supply our prospects with the absolute best know-how and merchandise.
We stay up for welcoming the Isovalent crew as soon as the acquisition closes and, collectively, defining the way forward for multicloud networking and safety.
