+Security Considerations
+=======================
+
+.. todo:: This doc is vague and just high-level right now. Describe architecture that enables security.
+
+The goal of securing a cloud computing system involves both protecting the instances, data on the instances, and
+ensuring users are authenticated for actions and that borders are understood by the users and the system.
+Protecting the system from intrusion or attack involves authentication, network protections,  and
+compromise detection. 
+
+Key Concepts
+------------
+
+Authentication - Each instance is authenticated with a key pair. 
+
+Network - Instances can communicate with each other but you can configure the boundaries through firewall
+configuration. 
+
+Monitoring - Log all API commands and audit those logs. 
+
+Encryption - Data transfer between instances is not encrypted.

 Cloud Computing 101
 ===================
 
-.. todo:: add in a brief tour of cloud computing concepts
+Originally the term cloud came from a diagram that contained a cloud-like shape to contain the 
-
+services that afforded computing power that was harnessed to get work done. Much like the electrical 
-
+power we receive each day, cloud computing is a model for enabling access to a shared collection of
-Overview of Cloud Computing
+computing resources - networks for transfer, servers for storage, and applications or services for 
-===========================
+completing work. 
-
 
 Why Cloud?
-==========
+----------
-
+Like humans supposedly only use 10% of their brain power, many of the computers in place in data 
+centers today are underutilized in computing power and networking bandwidth. People also may need a large 
+amount of computing capacity to complete a computation for example, but don't need the computing power
+once the computation is done. You want cloud computing when you want a service that's available 
+on-demand with the flexibility to bring it up or down through automation or with little intervention.
 
 Attributes of a Cloud
-=====================
+---------------------
+On-demand self-service - A cloud should enable self-service, so that users can provision servers and networks with little 
+human intervention. 
+
+Network access - Any computing capabilities are available over the network and you can use many different
+devices through standardized mechanisms. 
+
+Resource pooling - Clouds can serve multiple consumers according to demand. 
+
+Elasticity - Provisioning is rapid and scales out or in based on need. 
+
+Metered or measured service - Just like utilities that are paid for by the hour, clouds should optimize
+resource use and control it for the level of service or type of servers such as storage or processing.
 
 Types of Cloud Services
+-----------------------
+
+Cloud computing offers different service models depending on the capabilities a consumer may require. 
+The US-based National Institute of Standards and Technology offers definitions for cloud computing
+and the service models that are emerging. 
+
+SaaS - Software as a Service
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Provides the consumer the ability to use the software in a cloud environment, such as web-based email for example. 
+
+PaaS - Platform as a Service
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Provides the consumer the ability to deploy applications through a programming language or tools supported
+by the cloud platform provider. An example of platform as a service is an Eclipse/Java programming
+platform provided with no downloads required.
+
+IaaS - Infrastructure as a Service
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Provides infrastructure such as computer instances, network connections, and storage so that people 
+can run any software or operating system.
