By the Numbers: How Google Compute Engine Stacks Up To Amazon EC2

vu1986 writes "Google launched its EC2 rival, Google Compute Engine, last June, it set some high expectations. Sebastian Standil's team at Scalr put the cloud infrastructure service through its paces — and were pleasantly surprised at what they found. A note about our data: The benchmarks run to collect the data presented here were taken twice a day, over four days, then averaged. When a high variance was observed, we took note of it and present it here as intervals for which 80 percent of observed data points fall into."

      Sure it's fun to knock Google for shutting down services, but I believe most (if not all) of their shutdowns have always been free services they provide to consumers. I'm not aware of any paid Google service that has been shutdown. Though, Google has been known to drastically increase the cost of their services where it drives people away (mapping and AppEngine are 2 more recent examples, though they lowered the price of maps after a lot of people left).

      Google is trying to find services to hook people with, so they fund a lot of startup type projects to see what will hook people. When those projects don't produce the results they want, they just shut them down. But from what I've seen, those have mainly been free services.

The longer you remain involved in any legal activity, the more cost you are accumulating in terms of legal representation, lost effort as your staff responds to supoenas, etc. This is something you want to minimize if you can't eliminate it completely.

      Let's consider a basic hypothetical situation in which 'Illegal Data' is discovered on a service provided by Hosting Company 'HC'. The investigation starts by determining the chain of custody and the police will attempt to determine the 'owner' of the data, and the chain of custody of that data. HC responds to the police and provides the details of the customer that uploaded the data (according to HC's logs). Eventually the customer is charged with a crime. However, HC will be drawn into the investigation because the defense lawyer will be challenging the claims of the prosecutor with respect to chain of custody and validity of the logs provided by HC. HC will be compelled to provide data/testimony (not a defendant, offered immunity, etc). HC will have to spend a non-trivial amount of time collecting the information, preparing for testimony, etc. Even if you assume they were perfect with their logs, it's still a big cost to HC. And if they AREN'T perfect? Well they still have all the costs associated with testimony, and they may take a PR hit when that testimony reveals that their internal processes are less than ideal.

      Contrast that with the concept of encrypting the user data in a manner such that only the specific user can access/alter the data. The responsibility for HC to provide testimony is dramatically reduced. All they have to show is that they don't have the ability to mess with the data (other than deletion/copy) without the customer's key. Therefore the complexity of the chain of custody is reduced, and HC is basically 'out of the loop' with respect to the prosecution/defense. The prosecution doesn't need extreme information to prove that the data wasn't modified (since it can't be w/o the key) and the defense can't suggest that the 'illegal data' was placed in the encrypted container by HC. The burdon of proof falls to the defense, and not HC.

    I find it somewhat ironic that Microsoft will support Linux on its IaaS platform before Google will support Windows on theirs.

    Why is that ironic? The difficulty/pain for each of them to support the "other" OS isn't the same.

    Linux is easier for cloud providers. eg no license tracking, billing or activation type stuff (for most distros at least) to worry about, small Linux server instances require less resources than Windows, just a bunch of files to deploy - no installation processes, instance specific UUIDs etc

    Windows is harder (for everyone but MS) for the opposite reasons.

    Google would have to agree to whatever terms Microsoft would come up with, before they can support Windows on their platform. Microsoft can put Linux on their platform without having to get any sort of approval from Google.

    Has anyone had to interact with Google support for this? Is it anything like the other services?

    How many users is each service supporting? I'd be willing to bet AWS is supporting 20x the user count GCE has, so if GCE is only 4x faster on some things, put an AWS-equivalent load on them and watch how quickly they fall over.
