Moving Past the “Denial Phase” of Cloud Networking Problems

IT organizations have consistently overlooked one risk category that has haunted their cloud projects and agility aspirations: Operational connectivity to your cloud provider. An analyst put it this way: “Cloud providers built a beautiful highway, but left the on-ramps for the drivers to figure out.”

Amid all the excitement around Cloud-powered scalability, Network Engineers are still responsible for operating this organically growing animal that started off as a small pet (project). I have heard hours of grievances from networking professionals about Public Cloud implementations. The most common ones are:

  • Having to operate in a networking model built by an elite group of software engineers.
  • Lack of a networking console/CLI/UI for all-things cloud (across providers and regions).
  • Poor visibility for troubleshooting (like packet captures or advanced logging).

Does our industry acknowledge that we have a case of “lopsided Cloud agility” where networking is left far behind App development, Compute and Storage? There is a long list of capabilities that will help make Connectivity to the Public Clouds more reliable and consumable for enterprises. Numerous blogs document the unofficial wish-list of IT professionals. Here a few recurring questions:

  • How to design networks where the center of gravity is shifting to the public cloud? (CIDR allocations, multi Availability Zone implementations, cross-region strategy etc.)
  • How to handle overlapping IP addresses during migration to the cloud? (Application owners want to preserve IP addresses into the cloud)
  • How do we manage and monitor this framework with agility that the business demands?

I was pleasantly surprised last week when a series of incidents and announcements started addressing this issue:

Are we finally moving past the denial phase of the problem? Is this the beginning-of-the-end of lopsided agility? Comment below with your thoughts. Let’s share our collective learning and build connectivity and networking models that don’t get in the way of business goals.
