It’s getting harder and harder to decide whether to choose physical devices to do L4-7 processing (stateful- and web application firewalling, load balancing, VPN termination, WAN optimization) in your virtualized data center, or whether to deploy VM version of the same appliances.
Physical devices usually perform better. Virtual appliances are more flexible, but don’t scale well ... and Embrane just complicated your decision-making process: they launched scale-out distributed virtual appliance architecture and products that combine the best of both worlds.
Here’s the short summary for differently-attentive:
There’s a definite need for scalable virtual appliances in public and private cloud environments, and Embrane’s heleos architecture is one of the best proposed solutions I’ve seen so far. You should definitely consider them as part of your IaaS cloud solution – talk to them, ask for an evaluation, kick the tires ... and let me know how it works.
- Read the Embrane’s heleos: scale-out distributed virtual appliance article;
- Embrane published a pretty good white paper;
- I’ll describe Embrane’s architecture in the Cloud Computing Networking – Under the Hood webinar (register for the live session).
Disclosure: Embrane indirectly covered some of my travel expenses during the Networking Tech Field Day, but nobody has ever asked me to write about their products or solutions. Read the full disclosure (or more precise ones by Tony Bourke or Matt Simmons).
