The Cloud Defined, Part 8 of 8: Services Not Applications

This is the conclusion to my series of articles where I share my interpretation of the National Institute of Standards and Technology’s special publication 800-145. This week I share my thoughts on how cloud computing will change the roles of IT professionals. The biggest shift that this new era of cloud computing brings to the world of IT is that IT professionals will now transition from analyzing systems to ana

The Cloud Defined, Part 7 of 8: Deployment Models

I am continuing my series of articles where I share my interpretation of the National Institute of Standards and Technology’s special publication 800-145. This week the focus is on the four different deployment models of cloud computing according to the NIST’s definition: Private cloud. The cloud infrastructure is provisioned for exclusive use by a single organization comprising multiple consumers (e.g., busin

The Cloud Defined, Part 6 of 8: Service Models

I am continuing my series of articles where I share my interpretation of the National Institute of Standards and Technology’s special publication 800-145. This week the focus is on the three different service models of cloud computing according to the NIST’s definition: Software as a Service (SaaS). The capability provided to the consumer is to use the provider’s applications running on a cloud infrastructur

The Cloud Defined, Part 5 of 8: Measured Service

I am continuing my series of articles where I share my interpretation of the National Institute of Standards and Technology’s special publication 800-145. This week the focus is on the fifth and final fundamental characteristic of cloud computing according to the NIST’s definition: Measured Service. Cloud systems automatically control and optimize resource use by leveraging a metering capability at some level

The Cloud Defined, Part 4 of 8: Rapid Elasticity

I am continuing my series of articles where I share my interpretation of the National Institute of Standards and Technology’s special publication 800-145. This week the focus is on the fourth fundamental characteristic of cloud computing according to the NIST’s definition: Rapid elasticity. Capabilities can be elastically provisioned and released, in some cases automatically, to scale rapidly outward and inwar

The Cloud Defined, Part 3 of 8: Resource Pooling

I am continuing my series of articles where I share my interpretation of the National Institute of Standards and Technology’s special publication 800-145. This week the focus is on the third fundamental characteristic of cloud computing according to the NIST’s definition: Resource pooling. The provider’s computing resources are pooled to serve multiple consumers using a multi-tenant model, with different phys

The Cloud Defined, Part 2 of 8: Broad Network Access

I am continuing my series of articles where I share my interpretation of the National Institute of Standards and Technology’s special publication 800-145. This week the focus is on the second fundamental characteristic of cloud computing according to the NIST’s definition: Broad network access. Capabilities are available over the network and accessed through standard mechanisms that promote use by heterogeneou

The Cloud Defined, Part 1 of 8: On-Demand Self Service

For this and the next seven weeks I am going to change the focus of this blog from non-technical advice for IT professionals to an interpretation of the National Institute of Standards and Technology’s special publication 800-145. This is an often overlooked and incredibly important document for all IT professionals to read, study, and be familiar with as it is going to help everyone in our industry get on the sa
