Managed services providers (MSPs), and in particular IT Infrastructure-as-a-Service (IaaS) providers, that offer a variety of service types and service grades — both in-the-cloud and traditional managed services — are effectively best positioned to satisfy the range of enterprises’ application requirements. These requirements will naturally vary from those that “keep the lights on” to those that support limited business functionality, and will reflect the inherent value of systems that operate across the application lifecycle (i.e., development, staging, testing, and production). To meet these requirements fully, IaaS providers must
offer integrated cloud-based and traditional managed compute, storage, network, and security services — each with a range of features, performance service level agreements (SLAs), support levels, and corresponding price points.
This white paper reviews the evolution of data center outsourcing, and introduces cloud offerings within this historical framework. To help clarify the playing field, it presents a high-level overview of various cloud service types, narrowing the focus to infrastructure cloud offerings, and, more to the point, to those services in this market targeted to enterprise buyers.
