It’s sad but true. Enterprises at every stage of the cloud transformation journey are struggling to deliver fast, secure and consistent experiences at the scalability and price point that the multi-cloud world promised.
IaaS, PaaS, and application endpoints need to communicate at various levels for multi-cloud to work. The IaaS apps running in VPC or VNET need to be connected, secured, and optimized at the network layer. In contrast, PaaS or serverless apps can be attached only via the application layer using FQDNs. This level of complexity increases by magnitudes as enterprises move across other clouds and regions.
As a result of this complexity, cloud architects and operations teams spend most of their time manually stitching together disparate services across multiple data centers and public cloud environments—each one with different performance, reliability, and security postures. The result is increasing IT complexity, rising cloud costs, wide security gaps, and poor application experiences for users.
Cracking the multi-cloud nut has been fraught with frustration. It wasn’t supposed to be this hard, they said. But the reality is that enterprises are finding that they need to throw out decades of legacy networking strategy and rethink how they tie distributed infrastructures together in the cloud to deliver seamless experiences to anyone, anywhere.
Introducing Full-Stack Cloud Transit
To ensure their multi-cloud environment’s security, performance, consistency, and simplicity, enterprises need to build an intelligent fabric that automatically connects applications, services, and networks across cloud infrastructures based on pre-set operations, security, and performance requirements. This requires first solving the cloud connectivity issues discussed above and then building an app transit layer that is autonomous and machine-driven to mitigate inherent complexity. Combining Layer 3 Networking and Service Networking in a single solution provides a single architecture that simplifies and, most importantly, automates multi-cloud networking.
Layer 3 Networking:
Enterprises need a single cloud network that scales elastically to seamlessly interconnect VPCs and VNETs across any public and hybrid cloud. This allows cloud architects and operations teams to automatically orchestrate and connect all clouds with a flexible architecture that leverages cloud-native constructs. It also provides scalability with the cloud backbone, edge PoPs and integration with cloud-native gateways in regions and at the edge of the cloud environments.
Distributed apps in the cloud need more than connectivity. Once you’ve connected your cloud assets in a single environment, it’s time to build a dynamic, scalable app transit layer that allows you to deliver various services on top of any infrastructure. This layer leverage cloud-native app-networking and must be autonomous and machine-driven to mitigate complexity. It should give you a complete understanding of application types for per-app segmentation and end-to-end observability from L3 to L7 to diagnose security or performance problems across the cloud infrastructure.
One Platform to Rule Them All
Full-stack cloud transit manages all aspects of the cloud transit network stack—including security and performance—without the operational baggage or downtime of conventional networking. So, regardless of whether you’re using Transit Gateway in AWS or VNet peering in Azure, you’ll be able to orchestrate the connectivity between functions and clouds, select the best possible path and gain an accurate global view of your cloud networks and apps—all on one platform. Finally, unlocking the scale and scope of the multi-cloud world opens up a whole range of opportunities to improve the business and gain operational agility.
