Cloud computing: Introduction to Software as a Service

Date:  07 Oct 2011 (Published 18 Mar 2011) |Level: Introductory |

1. Get the basics on Software as a Service

Software as a Service represents the top, or application, layer of the cloud. Applications run in this space and are accessible to users on demand. Learn about the opportunities and challenges presented by SaaS.

2. Explore the attributes and components of Software as a Service

It’s important to understand these four SaaS concepts: Multitenancy: Lets the system deliver an application to multiple client organizations from a single instance of software. Provisioning: The automated process that manages computing resources, configurations, and processes and optimizes availability. Scalability: Lets the system scale storage needs (up and down) which reduces user costs and complexity for the storage provider. Billing module: A set of predefined billing policies, lets the system generate bills from resource usage data.

3. Consider the requirements and issues associated with SaaS security

As it is for all cloud service models, security is an important consideration for SaaS applications. Learn about SaaS security and how to mitigate risks to cloud services to ensure high uptime availability and security in a cloud environment.

4. Extend your SaaS applications with IBM and IBM Ecosystem Partners

Grow the functionality of SaaS applications with tools for collaboration, business analytics, application and resource management, and platform-based integration.

5. Go further: Gain more skills in cloud computing
