Basically this is true and this leads to the conclusion that instance types like (micro, small and medium) are quite underpowered compared to "today's" usage patterns right?
Of course Elastic Scaling is not possible. Because Hosting a server in a datacenter and having cloud instances are two different stories. If you have need for flexibility you can simply run a loadbalancer having your base hardware hosted for a good price at hetzner (or another datacenter you like) and then spin up some AWS Instances behind the loadbalancer for dealing with spikes.
Or as others have written you can buy 3 boxes at hetzner and scale 300% ;)
In my opinion a very good choice. I run a EX4 Box there and i'm more than satisfied with the service they provide.
Recently i fired up a Support Request around 5am and got a response 6am when their support team picks up work. during the day you usually don't have to wait longer than one hour for a support response.
They have awesome hardware for reasonable prices... i migrated everything i own from ec2 to one EX4 box with 8 cores and 16 gig of ram for less than i payed at EC2...

As someone stated in the comments. Wordpress isn't the solution to all. Mainly it's a blogging system with the possibilities to add some static content. Of course there are many plugins which enrich the wordpress expirience but a blogging system stays a blogging system at heart.
If you speak words like
* Document Management
* Workflow Management or
* Digital Asset Management
It's most likely you misunderstood Wordpress and it's capabilities from begin.
I personally use Wordpress for many purposes private and for professional work. But if the client's demands are to high i switch instantly to better suiting solutions (which does not mean that wordpress is bad but probably not suitable for all use-cases) which makes the client even happier.
About selling the right thing:
If you go to the customer and tell him "This one-shot solution will be Wordpress and you can do everything with it !" You already oversold it and probably you should speak with your business development guys ;)
One point i agree is the release schedule, which creates quite a lot of work trying to stay up to date with every wordpress instance you have. But i never saw the so called "perfect solution" not in OpenSource and not in "I pay fricken lot money for licences"-Software.
That's what i tought. Furthermore it feels a bit strange to listen to a 6th grade boy is talking about creating apps. But why, it's just the same as we did some years ago. Just the possibility to speak up has gotten better =)
But why creating something new when there are projects available like OpenWRT or DD-Wrt or Freifunk Firmware wich creates a Mesh-Network that works quite good? The only thing you need is standard Wi-Fi routers and those firmwares.
take /var/log as example. if someone floods your server with traffic and you log every tiny bit (or even worse you have the debug level set to on) the logs will quickly take lots of space. if the space is full no further write access is possible
if it's a seperate partition you can't write more logs... if it's on the same partition you won't be able to log in by ssh as example because your drive is full and you can't spawn the sshd agent ;)
Whats the point? Sensitive Information like the login page is secured by https (which is a great thing) but why encript the data you don't need to have encripted?
It's (for me) pretty simple. they force the users to use http because the amount of cpu time which is spent for http user is lower than the time for https...
Wow that is big news. I hope they don't hollow out the company to just get the people and the ideas behind the product. it's great (but has also some caveats).
Their Nosql idea has too great possibilitys.
And of course as stated by Kris they use lots of opensource in their Product.
