Navigating the Network: The Quest for Innocence in a World of Complexity

Welcome to the digital age, where the marvels of self-driving cars and sophisticated AI like ChatGPT grace our everyday lives. Yet, amidst these advancements, a battleground often goes unnoticed, hidden within the layers of our network infrastructures. It's a world where network teams are the unsung heroes, tirelessly working behind the scenes to keep our digital lifelines seamless and uninterrupted. Today, I want to take you on a journey through Network Observability, a beacon of hope in the relentless quest to avoid outages, understand the impact of change, and quickly and accurately root cause complex situations.

Accelerate AWS Access with Arista

AWS Cloud WAN Tunnel-less Connect and Arista CloudEOS integrate to accelerate cloud onramp

As cloud and multicloud adoption continue to evolve, public cloud providers like AWS continue to introduce more and more tools for enterprise IT to choose from. For example, customers can deploy a virtual router in a Transit VPC and BGP peer with AWS Cloud WAN to interconnect on-premises networks and AWS VPCs. However, GRE or IPsec tunnels are often required for the BGP peering, adding up the network complexity and increasing operational costs.

Modernizing the WAN from Client to Cloud

The evolution of WAN architectures has historically paralleled that of application architectures. When we primarily connected terminals to mainframes, the WAN architecture was largely point-to-point links connecting back to data center facilities. As traffic converged to remove OpEx-intensive parallel network structures, the WAN evolved to architectures that enabled site-to-site connectivity in a full mesh or configurable mesh and then enabled multi-tenancy for carrier cost optimization.

Arista Partnering with Google Cloud to Deliver Hybrid Cloud and Multi-Cloud Connectivity

Arista has a long history of joint development with hyper-scale cloud providers delivering innovative solutions for a broad range of customers.  Our integration with Google Cloud and Network Connectivity Center is a testament to that ongoing innovation and abstracting complex networking challenges making them simple and agile for IT clients worldwide.

Delivering a Multi Cloud and Cloud Native Operator Experience

Right around the same time I joined Arista in 2009, Amazon Web Services developed the concept of the Virtual Private Cloud, one of the seminal technologies that became a core construct deployed throughout public clouds enabling enterprise customers to corral and protect resources and provision them into logical groups, align security policies, and simplify their management. Following this, Google developed a model for Virtual Private Clouds that spanned regions allocating one subnet per region by default - creating the first multi-region VPC within a single cloud provider.
