From a technology perspective Mosso don’t provide root access to their severs. They provide servers with the OS and software pre-installed. Mosso claims that this gives them ability to easily monitor and scale the service as needed which frees the end user from having to worry about OS, load balancing, etc. How does this work ? Well, Mosso abstract the actual platform that you are working against. From a practical perspective this means that you end up with a single directory space in which you store file types (PHP, .RoR,etc). If a files is requested it is actually executed by the native platform. What does this mean ? It means that if you are executing ASPX files they will be handled by Windows, and if you are executing RoR files they will be handled by Linux, etc).If you have combinations that don’t appear to be supported then support will enable this for you.
This leads us onto a good differentiator that Mosso has over Amazon, their customer service is 24*7 manned by people at the end of the phone unlike Amazon. This can make a world of difference when actually trying to get something to work and I have to say their customer service is excellent.
Mosso currently only offers FTP access to your instances . No RDP, SSH etc, which of course you get with EC2 from Amazon. However right now, Amazon don’t really provide anything that competes with Mosso’s primary cloud offering whose value point are providing load balanced Windows and Apache based web applications, as well as semi-load balanced SQL Server and mysql offerings. This is what Mosso call Cloud Sites. Automated load balancing is coming from Amazon, but is not there yet, and right now you have to roll your own.
There is no concept of sharing image instances with Mosso as the core concept is different i.e.you aren’t working with 1 “virtual” instance but are really working with an interface that functions as a type of fascade to a potentially many instances. Having said that, Mosso are currently beta testing something they are calling “Cloud Servers” and it looks like this will be direct competition to EC2.
Update: Mosso Cloud Servers now goes live on March 16th. Pricing starts at $0.015/hour or $10.95/month. Check out the details here.They will also have an API. For a sneak look at the API email Mosso and ask . Also Cloud Files is out of beta on the 12th March 2009. Cloud Files is Mosso’s online storage service and CDN enabled static content serving engine. It has several new features. Check out all the details here.
Amazon has lots of extra services that they provide to interact with the cores instances such as S3, SimpleDb, SQS, CloudFront etc, and whereas Mosso has Cloud Files it does not have the breadth or extent of services that Amazon provide.
Another differentiator is the billing services. Right now Amazon do not provide hard copy billing invoices ( a particular bug bear on the Amazon forums) which prevents many organisations from actually using Amazon, whereas Mosso do provide this.
All in all, Mosso is a good cloud hosting solution. It’s value proposition is different from EC2 and whereas Amazon has more power and flexibility there is definately room for the service Mosso provides which is likely to get many people up and running quicker. It lacks the ability to have pre-configured AMI instances, so I won’t be able to get a pre-installed and configured Hadoop instance, or whatever, which for some is one of the attractions of EC2, but for being able to quickly having web applicaitons configured and load balanced it is perfect.
Commercially it does not follow the granular utility compute model that Amazon provides, as it has starter flat rate of $100 per month. This does include 50 GB storage space, 500 GB monthly bandwidth, 10,000 compute cycles, and also 24*7*365 live support chat.
So in summary Mosso has some unique differentiators:
– Different model that enables quick configuration and load balanced web applications
– 24*7*365 live support
– Hard copy Invoices
The way that Mosso is heading it provides a nice set of different features as well as some comparable offerings in the pipe that should ensure Amazon do not have everything their own way.
