Amazon Web Services

Amazon Web Services is well suited for companies or organizations that need to run specific applications or virtual services on servers. The cost-per-server ratio makes this ideal for testing and live deployment scenarios. It is especially ideal for smaller to medium size IT development teams. If you are looking to just set up a website, for example, AWS may not be ideal unless you are having it custom built.

Mirantis OpenStack

Mirantis is well suited for someone who doesn't mind spending money but doesn't quite want to commit to a cloud provider like AWS. It is also well suited for small or junior technical teams that don't have the skills, experience, or time to run their own openstack clusters.

Pros

  • AWS constantly innovates and iterates, announcing new features several times per year. Earlier this year, for example, they introduced provisioned IOPS for EBS, suddenly providing us with an inexpensive solution to a performance quandary we'd been facing.
  • AWS has provided us with access to the product owners and architects of the products we use most. In turn, those resources provided us with visibility into the product road maps. This enabled us to improve our long-term infrastructure planning, and avoid expensive features that we'd get for free later in the year.
  • AWS peremptorily lowers costs a couple of times per year. This has helped us keep our bill reasonable even as we consume more and more of the AWS services. We periodically compare the cost of AWS to the cost of moving into our colo, and every year the colo looks less and less attractive.

  • Works out of the box. There is very little back-end configuration necessary for users.
  • The support is active and response times are very good.
  • Staff is extremely knowledgeable and can help with more complex concepts and design ideas.

Cons

  • Occasionally, we disagree with their roadmap priorities. For example, we really needed Content-Based Routing added to ELB to support our multitenant implementation. The AWS architects agreed that it was a mainstream, valuable request and hinted that they were trying to get it onto the roadmap, but 15 months later there's still no sign of it. I'm sure they have their reasons, but it's a strange and annoying hole in an otherwise invaluable service.
  • AWS has had well-publicized outages that have broken the promise of true zone (datacenter) isolation. This was supposed to have been impossible - if you had instances running in two zones within a region, you thought had a solid survivability story. We were forced to react by building out additional redundancy that increased costs beyond our original design estimates. AWS claims to have resolved the problem, but we haven't been confident enough to spin down the extra servers yet.
  • There are annoying resource limits, presumably in place to prevent hackers from allocating huge numbers of resources on a compromised account. The problem is that raising the resource limits requires manual action to be taken, and can have a severe impact on production software if your ops team isn't meticulous in checking the limits. As of the last time I checked, these limits weren't available via API, making it impossible to create alarms whenever we get close to exceeding our resource limits.
  • AWS is relatively infamous for their poor communications during outages. Their status page will occasionally go without an update for 45 minutes, while half your customers are dead in the water. This is - obviously - infuriating.

  • Mirantis OpenStack managed services are expensive. Very expensive for a start-up.
  • I'd personally like to see a little more under the hood details in the status pages.
  • Mirantis could also benefit heavily from a free "light" version that start-ups could use to run their own cloud. Maybe coupled with advertising or some sort of surveys.

We are almost entirely satisfied with the service. In order to move off it, we'd have to build for ourselves many of the services that AWS provides and the cost would be prohibitive. Although there are cost savings and security benefits to returning to the colo facility, we could never afford to do it, and we'd hate to give up the innovation and constant cycle of new features that AWS gives us.

The management console is the weak part of the service in my experience. It is adequate but slow.

Performance

AWS does not provide the raw performance that you can get by building your own custom infrastructure. However, it is often the case that the benefits of specialized, high-performance hardware do not necessarily outweigh the significant extra cost and risk. Performance as perceived by the user is very different from raw throughput.

Alternatives Considered

This is the ONLY Web Service we have used since my time with the company to manage our weekly MP3 uploads. I'd say it stacks up pretty well since we have stuck with it over the years! Simple & Effective!

Mirantis is a managed service. If you're looking for that type of support, infra management, and to relieve yourself of the burden then they are a great option. If you're looking to build your own cloud and save as much money as possible then running openStack yourself is your best option. I would say in the category of OpenStack managed services Mirantis is ahead of Ubuntu (who uses JuJu to manage everything) but behind Rackspace

Return on Investment

  • Positive: Faster provisioning of infrastructure.
  • Positive: Lower upfront costs.
  • Negative: Integration of AWS to enterprise apps.

  • Mirantis did help our business figure out if openstack was right for us.
  • Using Mirantis I felt a bit cheated on understanding the deep technical knowledge of how openstack works. But that being said that is probably a value add more than a detractor for most people.
  • Using Mirantis was considerably cheaper than AWS.
