Two Phase Multi Cloud Networking Reality
- Multi-cloud networking splits into two problems: reliably connecting data centers to cloud, then networking inside and across clouds.
- Successful strategy focuses on consistent network policy, governance, and visibility across clouds plus connectivity back to datacenters.
SD WAN Tradeoffs Versus VPNs
- SD-WAN provides a transport-agnostic overlay that unifies varied links and enables traffic engineering compared with basic VPNs.
- It still needs appliances deployed in each cloud/region and adds overhead for HA, multi-region DR, and differing cloud behaviors.
Virtual Colos Vs Managed Cloud Exchange
- Colocation-based cloud interconnects (virtual colos) solve private connectivity and SLAs but bring hardware, lifecycle and ops overhead.
- Alkira offers a cloud services exchange built on hyperscaler infra: virtual exchange points as a managed alternative.
