There are absolutely a ton of use cases where cloud usage makes absolute sense, from both business and technical perspectives. I do not agree that 'nobody should be using cloud providers'. There is a place for its use, and it can be very beneficial when used strategically and thoughtfully. However, as we see every time a major cloud provider has an outage, lots of people don't use it strategically or thoughtfully, and that's really my point. Randy said it most succinctly I think. Cloud providers don't reduce your risk, they just have different risks to consider.

Few comparisons are obviously and exclusively better or worse. It is attractive to think of them as such, because it removes a lot of uncertainty and complexity in decision making.

My rule of thumb is, if you do it, sell it. If you're not going to sell it, buy it. Be it email, compute, data centre. If you're going to bother with your own compute infra, you should be selling cloud to capitalise those investments. -- ++ytti

I don't agree that cloud does not make business sense to anyone. There is a reason why Amazon, Microsoft and Google are milking it right now, so that is not even a discussion. What I do agree with is that the loss of control of operating your network yourself does present a risk. But that is a personal position, and has no bearing on the ultimate sensibility of offloading your infrastructure to a cloud that is likely to run it better than you, most of the year. It's one of the reasons I have no desire to work for an MNO as a hardcore engineer - I can't stomach the idea of being a vendor's project manager :-). Doing the 1st server properly costs several million euros a year, since you need competent 24/7 staffing, with sick leaves, holidays (in 1st world countries where this is a thing) and attrition taken into account.

If we need to own everything, where does it end? What can we get from 3rd parties? NAND gate? Or can we at least assume we don't have to build hydrogen atoms? That we get hydrogen atoms from elsewhere and start from that? Why is it that always the objection is something contemporary but the rest of the stack is fine to be provided by a 3rd party? If you believe you're living in a special period of time, where there is fundamental change to this, your position is statistically weak. Yep, agree with all this. As I've said many times before, classic telco is no longer a model the way it used to be, and I hope that rather than fight content the way we've been doing for the past 20 years - and failing dismally - we can use this opportunity to actually work together and stay relevant, FWIW. The tides are shifting, and going against the wind has continuously worked against us. Personally, I welcome content getting involved in back-end infrastructure. It may be bitter taste for classic telco, but it significantly improves the opportunity to connect more people, more affordably. Can't argue with that. Mark.

What content are doing by getting in on the game is, really, to open up the industry to other players that may want to either run their own private cellular networks, or start new mobile businesses at whatever scale they can muster, without having to lay out a ton of fresh capital in terms of money and people, to get going. There is still room for both classic MNO and content-backed infrastructure. Which one wins out in the end is a matter of time, but it's great for the user, because they just want to get connected. They don't really care, anymore, who gives them that connection, as long as it works and doesn't break the bank. Mark.

So yeah, it sort of mirrors my thinking... there is certainly some ways to go for AWS (and Google, and Microsoft) to catch up with the establishment. However, as we've seen in the past, these things happen quickly, and legacy always seems to get taken by surprise. The question is whether telco has learned from its past mistakes, of doing whatever it can to keep content out by either delivering its own "inferior" app alternatives, or attempting to block content from riding the network. Things could have been different for telco if we didn't try to rent-seek from content 20+ years ago, which forced them to build out on their own and run networks even larger than telco could ever dream of. Will telco hold on tightly to their edge gear and spectrum, while content tries to take the EPC core, or will they, for once, have a meeting of the minds? The next half-decade should fun to watch.

I've seen MNO's partner with other providers to run a VLAN for their service on their wi-fi network. For various reasons, one of which involves ease of use by an MNO customer, it hasn't really taken off. Reminds me of the days when you needed to insert a login and APN to access the GPRS network between 2007 - 2009. Adoption of mobile data became so much simpler when the phones and SIM cards came pre-configured to "just connect" to the data network. It's nice to see your mobile provider's SSID on some random wi-fi hotspot. But if using it is such a drama, folk will be happy to struggle with 3G or even EDGE. Mark.

Yes - WiFi Offload is more attractive to MNO's than building out more base stations, I believe. The problem is that it's easier if they could do this without also having to roll out a large scale wi-fi network, themselves. So they have to focus on one, and I've tended to find wi-fi deployments by MNO's take more of a back seat, as it's about reaching as many customers as possible, even at the lowest common denominator of performance.

Well, considering that this service is built both for private and public 5G use-cases, I imagine the product is elastic enough to support whichever business model a non-traditional operator may want fulfilled. For AWS, the infrastructure is already there. Whether you are looking to service 500 or 500,000 customers, it'd all be an extension for them. Mark.
