Planning for Cloud Computing

Introduction

Cloud computing promises to tackles two hitherto irreconcilable IT challenges: the need to lower costs and the need to boost innovation. However, it will take a lot of effort from enterprises to actually make it work. Instead of moving their IT mess for less somewhere else, the ill-prepared will end up with their IT mess spread across a wider area. This report explains why.

Features and benefits

  • The report help understand which benefits and risks relate to which type of cloud computing offerings
  • The report puts in context cloud cost, security, reliability, availability, scalability, service level agrements (SLAs) and governance issues
  • The report looks at the impact of Cloud computing on IT in general and IT service management in particular.

Highlights

Look to what the cloud can offer and where it might best be applied, rather than being so preoccupied with its shortcomings that you fail to recognize its value. Avoid the temptation to impose the full baggage of legacy IT expectations, requirements, and regulations on cloud services.Cloud computing as a term may have a use-by date, but the technical, operational, and commercial innovations behind it are here to stay. Cloud computing is a real innovation in the logic of how IT is sourced and managed and how services are delivered, and its use will grow steadily over the next 12 months.Adoption is a two-way street. It is not just about whether cloud computing is ready for you: it is, more importantly, about whether or not you are ready for it. The fact is that many enterprises are currently not ready for private or public clouds or any type of hybrid in between.

Your key questions answered

  • Why the public cloud market is more complex than expected. How private clouds are catching up with public cloud capabilities.
  • Why hybrid clouds are the next frontier for the enterprise.
  • Why public cloud pricing structures are evolving, but not always for the better
  • Why service-level agreements (SLAs) are key to cloud adoption.
  • Why security is the number-one cloud quality of service (QoS) concern and why reliability and availability are under increasing scrutiny.

    • from upfront license to subscription to PAYG, and back
    • towards greater price transparency - within limits
    • Public cloud price diversification will be limited by IT systems
    • 3.4 Private clouds put public cloud costs in context
