Re: Foggy subject
That does make a lot of sense, Bill. I actually chatted with a software engineer about this a few weeks ago. He works for a company that facilitates the filing of flight plans and preflight checklists and airplane manuals, and he needs a fully functional and fully synchronized set of applications running concurrently at different hubs around the world. Sounds like the fog might be a good option.

Re: Foggy subject
Why not both? In some cases, organizations already have privately owned data centers which are regionally located. On other cases - companies can utilize the public cloud infrastructure and just create hybrid connections.

The beauty of the cloud is its flexibility. I do believe, however, that a lot of customers are leveraging public cloud components to help bring data closer to the user. It just makes sense -- less of a hardware investment, pay-as-you-go model, and lots of resources available on demand.

Re: Foggy subject
Fantastic - thanks for this explanation, Bill. It sounds as though, in order to achieve this successfully, you need to leverage datacenter locations that are in relative proximity to your user bases. In your estimation, are companies doing that mostly by partnering with cloud providers or by colocating their own equipment in distributed facilities?

Re: Foggy subject
@Michael.Steihart - Happy 13th! When Cisco and Akamai joined forces, they helped develop the concept of the Fog. However, with a massive amount of edge networking happening now - the technology has gone far beyond Cisco.

The idea behind operating at the edge revolves around SDN, high-end caching, and workload delivery. This doesn't only revovle around Akamai. In fact, edge networking is completely influenced by WANOP, Ehternet Services, and the overall cloud computing infrastructure. Organizations are creating their own Fog Networks which don't include any components form Cisco.

By creating private links to localized data centers - these semi-private clouds bring data much close to the user. For example - you have a Silver Peak, F5 or NetScaler in place. By using elements of SDN, you're able to route users based on proximity to the nearest data center -- thereby reducing latency and hops. In that scenario, we're not usnig Akamai but rather geo-location to bring data closer to the user.

The really cool part about the Fog, or edge computing, is how it incorporates advanced technologies (SDN, virtualization, storage optimization) into the user enhancement process.

So - to create your fog - you have to think about what you're delivering, user locations, and quality of service metrics. In many cases, you can bring the data close to the edge without using Akamai.

Great story for a Friday the 13th, Bill! But what or how does a company leverage edge computing? Is it just a matter of calling Akamai and uploading all your VMs?
