What are the main area of cloud and what are relevant for us?
The three main are for cloud are:
Software as a Service (SaaS): The capability provided to the consumer is to use the provider’s applications running on a cloud infrastructure. The applications are accessible from various client devices through either a thin client interface, such as a web browser (e.g., web-based email), or a program interface. The consumer does not manage or control the underlying cloud infrastructure including network, servers, operating systems, storage, or even individual application capabilities, except for limited user-specific application configuration settings. In this case, customer does not need to manage any technical aspect like infrastructure or application deployment. With this approach, our customer, just need to use the Qlik platform without any extra effort in term of configuration or maintenance.
Platform as a Service (PaaS): The capability provided to the consumer is to deploy onto the cloud infrastructure consumer-created or acquired applications created using programming languages, libraries, services, and tools supported by the provider. The consumer does not manage or control the underlying cloud infrastructure including network, servers, operating systems, or storage, but has control over the deployed applications and possibly configuration settings for the application-hosting environment. In this case, customer can deploy our Qlik solution in a partner environment (i.e. AWS or Azure) that can manage the more technical and infrastructure aspect but our customer can choose how to deploy Qlik and manage application configuration. With this approach, our customer does not need to buy the hardware infrastructure and does not need to manage it.
Infrastructure as a Service (IaaS): The capability provided to the consumer is to provision processing, storage, networks, and other fundamental computing resources where the consumer can deploy and run arbitrary software, which can include operating systems and applications. The consumer does not manage or control the underlying cloud infrastructure but has control over operating systems, storage, and deployed applications; and possibly limited control of select networking components (e.g., host firewalls). In this case, customer can deploy our Qlik solution in a partner environment (i.e. AWS or Azure) that can manage the more technical and infrastructure aspect but our customer can choose how to deploy Qlik and change some infrastructure configuration. With this approach, our customer does not need to buy the hardware infrastructure. As mentioned, we at Qlik are most interested in the SaaS model so it is important when discussing it or Qlik Sense Cloud that we know precisely what it is. Simply stated, SaaS is “a software delivery model in which software is consumed off premise and with a subscription pay model. It is sometimes referred to as "on-demand software.” SaaS is typically accessed by users using a web browser.”
