What tools and vendors are folks using for multicloud networking scenarios?

Hey folks,

I'm curious to hear how folks are managing multicloud networking setups. With so many tools and vendors in the space I'm eager to hear what everyone is using to connect between different cloud environments.

• What vendors or solutions are you using to manage multicloud networking? (e.g., Equinix, Megaport, Aviatrix, Cisco, etc.)
• Are you using Layer 3 or 4 networking for your interconnections?
• Which cloud providers or service providers are you connecting to?
• What’s your primary use case for these connections? (access to specific cloud services, redundancy, cost optimization, etc.)

Feel free to share any challenges you've faced too!
