On a recent client engagement I was asked to provide a simple set of definitions for basic terms and concepts around Software-as-a-Service and Cloud Computing (which I often use inter-changeably). What was interesting is that there is a lot of buzz out there but I can see why people get confused because there isn’t a standard set of definitions.
So my Friday contribution to the SaaS industry I am publishing the Montclare’ SaaS Glossary of Terms. I would be interested in your feedback on the definitions and if I miss any key ones.
| Term | Definition |
| ACV | Annual Contract Value of a subscription software agreement. |
| API | Application Programming Interface. |
| ARR | Annual Recurring Revenue. |
| ASP | Application Service Provider. Typically associated with a hosted single tenant software solution. |
| CAC | Customer Acquisition Costs. A key -SaaS metric that measures sales effectiveness based on how long it takes to pay back Sales and Marketing investments. |
| Churn | A SaaS measure of customers who do not renew their annual or monthly subscription agreement. |
| Cloud Computing | A utility computing method that shares many types of computer resources through virtualization and delivers an elastic computing environment over the Internet. |
| CLTV | Customer Lifetime Value. A key SaaS metric that is used to measure customer value, usually over 3 to 5 years. |
| CMRR | Contracted Monthly Recurring Revenue. A key SaaS metric that is calculated for new customers, up-sells, cross-sells and removing churning customers. |
| CoLo | Co-Location facility. A term for leasing a third party’s physical data center infrastructure, which usually includes the building, power, Internet connectivity and security. |
| Cross-Sell | A key SaaS metric measuring new software functionality or modules added to an existing software subscription agreement. |
| Down-Sell | A key SaaS metric that measures when customers remove of functionality, users or capability that lowers the CMRR. |
| Freemium | A business model in which the SaaS or Cloud Computing provider offers basic features to users at no cost and charges a premium for supplemental or advanced features. |
| Hosted Software | Single tenant software that is delivered over the Internet from either the Software vendors own data center or through a third party hosting company. |
| IaaS | Infrastructure-as-a-Service refers to a combination of hosting, hardware, provisioning and basic services needed to run a SaaS or Cloud application that is delivered on a pay-as-you-go basis. |
| Mashup | It is a web application that combines data or functionality from two or more external sources to create a new service. The term implies easy, fast integration, frequently using open APIs and data sources to produce results that were not the original reason for producing the raw source data. |
| MRE | Monthly Recurring Expenses. |
| MRR | Monthly Recurring Revenues. |
| MSP | Managed Services Provider. Usually a hosting or CoLo provider who provides a higher level of application management services (App management, monitoring, reporting, billing and call center support). |
| Multi-tenancy | Refers to a software architecture where a single instance of the software runs on a server, serving multiple client organizations (tenants). Multi-tenancy is contrasted with a multi-instance architecture where separate software instances (or hardware systems) are set up for different client organizations. |
| On-Demand | Is often used as an interchangeable term along with SaaS. |
| On-Premise | Traditional method of installing and customizing software on the customer’s own computers that reside inside of their own data center. |
| Platform-as-a-Service (PaaS) | Platform-as-a-Service solutions are development platforms for which the development tool itself is hosted in the Cloud and accessed through a browser. With PaaS, developers can build web applications without installing any tools and then they can deploy their applications and services (reporting, integration, security) without any specialized systems administration skills. |
| Private Cloud | Employs Cloud Computing principles within a customer’s own internal networks. The term implies that the same virtualization and highly flexible and scalable methods used in huge Internet-based enterprise datacenters. |
| Public Cloud | Cloud Computing conducted using the public Internet outside of any enterprise firewall. |
| Renewal | Agreeing to extend an existing software subscription agreement beyond the initial term. |
| SLA | Service Level Agreement. The contractual terms of service associated with SaaS provider’s offerings. |
| SOA | Service Oriented Architecture. |
| SaaS | Software-as-a-Service refers to multi-tenant software delivered over the Internet and customers consume the product as a subscription service that is delivered on a pay-as-you-go basis. |
| Subscription | SaaS licensing method where customers rent their software from the provider usually over a 1-3 year period. |
| TCV | Total Contract Value. Total value of a transaction as measured over the term of the agreement. |
| Up-Sell | A key SaaS metric measuring additional software functionality, users, or capacity that is sold onto an existing software subscription agreement. |
| Virtualization | The creation of a virtual (rather than actual) version of an operating system, a server, a storage device or other network resources. |
