Describe cloud service types 3/3
Which cloud service type is most suited to a lift and shift migration from an on-premises datacenter to a cloud deployment? A. IaaS B. PaaS C. SaaS
A. With an IaaS service type, you can approximate your on-premises environment, making a lift-and-shift transition to the cloud relatively straightforward.
What type of cloud service type would a Finance and Expense tracking solution typically be in? A. IaaS B. PaaS C. SaaS
C. SaaS provides access to software solutions, such as finance and expense tracking, email, or ticketing systems.
Some common scenarios where PaaS might make sense include: ________ framework: PaaS provides a framework that developers can build upon to develop or customize cloud-based applications. Similar to the way you create an Excel macro, PaaS lets developers create applications using built-in software components. Cloud features such as scalability, high-availability, and multi-tenant capability are included, reducing the amount of coding that developers must do. _____________ or _______intelligence: Tools provided as a service with PaaS allow organizations to analyze and mine their data, finding insights and patterns and predicting outcomes to improve forecasting, product design decisions, investment returns, and other business decisions.
Development framework: Analytics or business
Some common scenarios where ____ might make sense include: Lift-and-shift migration: You're standing up cloud resources similar to your on-prem datacenter, and then simply moving the things running on-prem to running on the IaaS infrastructure. Testing and development: You have established configurations for development and test environments that you need to rapidly replicate. You can stand up or shut down the different environments rapidly with an IaaS structure, while maintaining complete control.
IaaS
In a ____ environment, the cloud provider maintains the physical infrastructure, physical security, and connection to the internet.
PaaS
In the ____ model, the cloud provider will also maintain the operating systems, databases, and development tools.Think of PaaS like using a domain joined machine: IT maintains the device with regular updates, patches, and refreshes.
PaaS
Some common scenarios for ______ are: Email and messaging. Business productivity applications. Finance and expense tracking.
SaaS
__________ as a service (SaaS) is the most complete cloud service model from a product perspective
Software
In an IaaS model, the _________ is responsible for maintaining the hardware, network connectivity (to the internet), and physical security. You're responsible for everything else: operating system installation, configuration, and maintenance; network configuration; database and storage configuration; and so on. With IaaS, you're essentially renting the hardware in a cloud datacenter, but what you do with that hardware is up to you.
cloud provider
The shared responsibility model The ______ is responsible for maintaining the physical infrastructure and its access to the internet, just like in IaaS.
cloud provider
The shared responsibility model applies to all the cloud service types. SaaS is the model that places the most responsibility with the__________ and the least responsibility with the _____
cloud provider user
PaaS is well suited to provide a ________ development environment without the headache of maintaining all the development infrastructure.
complete
In a SaaS environment you're responsible for the ____that you put into the system, the devices that you allow to connect to the system, and the users that have access.
data
Nearly ______ else falls to the cloud provider. The cloud provider is responsible for physical security of the datacenters, power, network connectivity, and application development and patching.
everything
While the SaaS model may be the ______ flexible, it's also the easiest to get up and running. It requires the least amount of technical knowledge or expertise to fully employ.
least
PaaS - They also ______ the operating systems, middleware, development tools, and business intelligence services that make up a cloud solution
maintain
Infrastructure as a service (IaaS) is the most flexible category of cloud services, as it provides you the _______________ amount of control for your cloud resources.
maximum
Platform as a service (PaaS) is a ______ground between renting space in a datacenter (infrastructure as a service) and paying for a complete and deployed solution (software as a service).
middle
Depending on the configuration, you or the cloud provider may be responsible for _____________ and ___________ within your cloud environment, network and application security, and the directory infrastructure.
networking settings and connectivity
In a PaaS scenario, you don't have to worry about the licensing or _____ for operating systems and databases.
patching
With SaaS, you're essentially ____ or ____a fully developed application. Email, financial software, messaging applications, and connectivity software are all common examples of a SaaS implementation.
renting or using
The _______ responsibility model applies to all the cloud service types. IaaS places the largest share of responsibility with you. The cloud provider is responsible for maintaining the physical infrastructure and its access to the internet. You're responsible for installation and configuration, patching and updates, and security.
shared
The shared responsibility model applies to all the cloud service types. PaaS splits the responsibility between _____ and _____
you and the cloud provider
