Lecture 10 - Software-As-A-Service (SAAS)
How is SAAS applied and how are the solutions specialized?
SAAS is applied at the application end using highly special application interfaces by users SAAS solutions are highly specialized towards one specific application goal (private/business)
What is the AWS Amazon Sagemaker built on?
AWS Amazon Sagemaker build on top of IAAS EC2 related services in order to use Inference code and training images used for machine learning compute instances AWS Amazon Sagemaker build on top of IAAS S3 services in order to store training data or machine learning models
What is the AWS Amazon Sagemaker?
AWS Amazon Sagemaker is a SAAS oriented service that provides fully managed instances running Jupyter notebooks that include examples training & tuning various machine learning models
AWS Sagemaker Example - SAAS Pricing & Machine Learning
AWS Amazon Sagemaker offers various usage models from building on-demand machine learning notebook instances to on-demand machine learning training & model deployment instances that all have different price ranges
SAAS CRM ZOHO Example - Online Social Networking Links (how does it work?)
CRM systems pull as much data about customers together as possible from different sources like E-Mails, purchase orders, transactions, communication, and even Online Social Networking sites
What is the largest SAAS market?
Customer Relationship Management (CRM)
Service Level Agreements (SLAs)
IAAS/PAAS/SAAS cloud models are offered based on various Service Level Agreements (SLAs) between the cloud service providers and the end users or the user organization of services SLA for clouds address service availability, data integrity, privacy, security, data protection, etc.
What does the Jupyter Tool do?
Jupyther enables the creation and sharing of source codes using so-called 'Jupyther notebooks' Jupyther notebooks contain live code, equations, formulas, visualizations & explanatory text
What are Enterprise Resource Planning (ERP) and Customer Relationship Management (CRM)?
Modern Software Delivery Models (SAAS)
SAAS Licensing - Freemium Model Example
SAAS enables the use of the freemium model that is a free service (e.g. in order to 'hook' customers) with limited functionality and scope whereby fees are often charged for enhanced functionality or for a larger scope of usage
What is SAAS based on?
SAAS is based on easy accessible software remotely accessed via Web browsers and centrally hosted in data centers
SAAS CRM Freshsales Example - Application Interface (what does it look like?)
SAAS specialized application interfaces enable users to focus on one particular domain of business or private concern and do not mention any underlying IAAS IT resources nor PAAS IT components
Horizontal Scalability enabled by Virtualization
The SAAS horizontal scalaing is a core feature and often implemented in practice whereby one version of the application is installed on multiple virtual IT resources in a cloud infrastructure
SAAS Multitenant Architecture
The SAAS multitenant architecture refers to a single version of the software application with a single configuration (w.r.t. hardware, network, OS) that is used for all customers (aka 'tenants')
The Conceptual ideas and key usage of the SAAS cloud service model
include consume applications, avoid installations, special interfaces & ready-to run applications
