Gartner reinforces what many in the cloud industry believe: Amazon Web Services is the 800-pound gorilla. The company is "extraordinarily innovative, exceptionally agile and has one of the richest IaaS portfolio of services." Its large pool of capacity in the cloud optimizes it for batch computing, high-performance computing and big data analytics. It has a large technology ecosystem, which makes running licensed and packaged software easy to do in its cloud. While seen as a strong player in startup communities, AWS has been pushing its enterprise services as well recently. It releases security audits to customers under non-disclosure agreements, but it does not allow customers to do independent audits, Gartner points out.
There are some concerns, though, Gartner says. Namely, AWS has a "weak, narrowly defined" service-level agreement (SLA), which requires customers to spread workloads across multiple availability zones and only counts a violation of the SLA when both AZs are inaccessible. The SLAs also do not include the company's popular Elastic Block Storage, which recently suffered an outage. AWS is a price leader, but its services come with hidden extra costs, specifically around networking services and add-ons for highly available and fault-tolerant systems, Gartner says.

Bluelock - The VMware public cloud
Bluelock is about the closest thing you'll get to a VMware public cloud. The company is part of VMware's vCloud Data Center Service, meaning it leverages VMware tools to power its offering. It is one of the first to roll out new VMware features and its product roadmap is aligned with that of VMware's, Gartner says. As a member of the VMware public cloud ecosystem, it allows customers to federate workloads with other vCloud Data Center service providers as well. It has a "Portfolio" service, which provides monitoring of IaaS resources and advises customers on how to optimize workloads.
