SUMMARY

Impact

Ovum view

Public clouds QoS is under close scrutiny

Public cloud SLAs need to improve

Security is the number-one QoS issue

Private clouds will find it hard to keep up with the public cloud Joneses

Private clouds will converge with public ones

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 SLAs

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 clouds security credentials will take time to mature

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 COMPUTINGS 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

Recommendations to users

Put your use of public clouds in context

Leverage public cloud SLAs competition

Adopt a balanced approach to security

Always have a plan B

Adopt a holistic approach to public, private, and hybrid clouds

Recommendations to vendors

Focus on the business outcome rather than technical issues

Improve and diversify SLAs

Be transparent and proactive

Build your security credentials on openness

Help enterprises make the right technology and design choices
