Rackspace vs Amazon impressions

I’ve been a customer of Amazon Web Services since they have been in beta. I’ve also worked with Rackspace now and then. Lately I’ve been working extensively with Rackspace infrastructure so I have a better understanding of their products. Bellow there are a few things that bother me at Rackspace:

Instances

The thing you are going to use 99% of the time with any of the providers. Amazon offers normal instances, high cpu instances, high memory instances, huge memory and cpu instances. On Rackspace you will have a very limited offer of instances. No high cpu or high memory. They do have plans to add them in nearby future. Until then, if you have a CPU bottleneck then it’s tough luck: scale up the instance and pay double.

And since we are talking about pricing for instances, Amazon is cheaper on the long run due to Reserved Instances (you pay an upfront fee and lower price/hour for the instance after). Amazon has been cutting down prices several times. Rackspace? Never.

Block storage

Called EBS on Amazon or CBS on Rackspace, it’s the preferred way of adding extra space to running instances without upgrading them. Beware that on Rackspace it takes an horrible amount of time to do a snapshot. I had to contact RS support several times because of this.

MySQL instances

Called RDS on Amazon or Cloud Database on Rackspace, they are basically optimized instances that run MySQL, but you are not given SSH access to them. Here Rackspace has the worst offer:
no scheduled backups (RS recommends mysqldump … lol try to do mysqldump for 10GB+ of data)
no replication (really? I couldn’t replicate my database)
no hotspare (Amazon MultiA-Z)

The good thing about Cloud Database is that they are fast. Really fast. Also RS promised to address all the above things in the nearby future (yeah).

Load Balancing

Rackspace does not support LB inside private network. Come on RackSpace, do your homework. This thing has been working for AWS since ancient history.

Conclusion:

There are many other things that need to be discovered, probably not pleasant ones. So far I am disappointed with Rackspace and what it has to offer and I would recommend to any customer to use Amazon instead.
