Public clouds’ QoS is under close scrutiny
Public cloud providers claim superiority over on-premise IT infrastructures on two fronts: cost and QoS. On-premise IT supporters counter-attack at both levels, but the brunt of their offensive focuses on QoS – with a mix of valid criticisms and hyped assertions aimed at generating FUD (fear, uncertainty, and doubt). Public cloud providers should expect the criticism (and FUD) to continue in its intensity.
Public cloud SLAs need to improve
The market is slow to trust that public cloud service providers will deliver on their RASS promises – all the more since the service-level agreements (SLAs) that back these promises are skewed in favor of the providers. Market trust will build up, though, as SLAs, backed by certification schemes, improve. Those with QoS requirement levels for which public clouds cannot cater will keep to private clouds (including shared or virtual private clouds, or both).
Security is the number-one QoS issue
Security concerns are the most important obstacle to public cloud adoption, along with concerns related to regulatory compliance and data governance. However, public cloud risk can be managed like any other risk. It requires vendors, users, auditors, and governments to cooperate – a process that has started but will prove slow-moving.
Private clouds will find it hard to keep up with the public cloud Joneses
Enterprises’ QoS expectations are rising. The rise affects both private and public clouds. The more demanding enterprises become with public cloud SLAs and QoS at all (RASS) levels, the more likely the same enterprises will be to make the same demands of their IT departments. Considering the status of many internal data centers, public cloud providers may find it easier to meet these demands than IT departments.
Private clouds will converge with public ones
In order to deliver satisfactory QoS and SLAs, public cloud providers have made technology and design choices that enterprises may not be able or willing to make. Both sides are on a convergence path, though. On one hand, enterprises will take a step forward and, for example, rethink how best to design new applications for scalability. On the other hand, public clouds will take two steps back. Many have chosen designs and technologies that have yet to become mainstream. These will evolve towards approaches that are more familiar to developers, or will mask the “exotic” elements of their approaches, especially when it comes to platform-as-a-service (PaaS) offerings

Key messages
SLAS ARE KEY TO CLOUD ADOPTION
Enterprises are adapting to public clouds’ QoS
QoS is a priority for both vendors and users
Users’ attitudes are evolving rapidly, within limits
Users put public cloud use in context
This context will increasingly be that of supply chains, not just individual suppliers
Users will have to improve the way they manage SLA
Public cloud providers need to manage the gap between QoS hype and SLA reality
The gap fuels skepticism
The gap will take time to narrow
The gap has already started to narrow
Public cloud SLAs will standardize and diversify
SLAs will standardize
SLAs will diversify
SLAs are central to the notion of private and hybrid clouds
QoS concerns fuel the rise of private clouds
Private cloud SLAs will have to keep up with the public cloud Joneses
Enterprises mitigate public/private cloud risks with hybrid mix
SECURITY IS THE NUMBER-ONE CLOUD QOS CONCERN
Trust in public clouds is growing, but security concerns fuel interest in private and hybrid clouds
Enterprises find it difficult to grapple with public cloud security issues
Despite the hysteria surrounding security issues, cautious trust is growing
Security concerns fuel the rise of private and hybrid clouds
Public cloud security needs more work
Public cloud providers have a holistic approach to security

Public cloud security begins at home
Public cloud security is an extension of internal security efforts
Users’ security efforts depend on the type of public cloud
Public cloud security requires a redesign of current security approaches
Public clouds increase the importance of data security
Public clouds require strong identity and access management
Compliance is more of a concern than security
Security, not compliance, should come first
A more balanced approach to risk management is required
Certification is key to cost-effective and balanced security and compliance
Certification schemes will take time to emerge
The public sector is a key participant in the security and compliance debate
Governments are still grappling with the cloud-computing phenomenon
Their role is particularly important when it comes to data governance
Finding the right balance between regulation and economic development
RELIABILITY AND AVAILABILITY ARE UNDER INCREASING SCRUTINY
Reliability and availability are growing public cloud concerns
Public clouds assume constant failure
Public clouds have a relatively good reliability record
Public clouds can fail
Users are increasingly concerned about reliability and availability
Public cloud providers need more transparency
Reliability and availability are both a problem and an opportunity
Reliability and availability are private and hybrid cloud objectives
Data center as it stands and should be
A hybrid cloud issue
SCALABILITY UNDERPINS CLOUD COMPUTING’S ELASTICITY
Scalability is public clouds’ number-one feature
Scalability positions public clouds well against private clouds and outsourcing
Public clouds have different scalability profiles
Public cloud providers are open about their scalability recipe, within limits
Scalability is a goal for private clouds, too
Size matters
Scalability via sharing
Different perspectives on scalability
THE ROAD TO PRIVATE CLOUDS REQUIRES NEW THINKING AND SKILLS
Public clouds open up new avenues
A renewed debate around how best to deliver QoS
Public clouds challenge conventional wisdom on a variety of fronts
Public and private clouds will converge, within limits
Public cloud technology and design choices will not be fully adopted by private clouds
Private clouds will take one step forward
Public clouds will take two steps back
Convergence will be fueled by hybrid clouds
RECOMMENDATIONS
