When an organization opts for a cloud service where they only need to manage and configure the operating system, it is referred to as ________.
- Database as a Service (DBaaS)
- Infrastructure as a Service (IaaS)
- Platform as a Service (PaaS)
- Software as a Service (SaaS)
Infrastructure as a Service (IaaS) provides users with virtualized infrastructure components. Organizations manage and configure the operating system, applications, and data on top of this infrastructure while leaving hardware management to the cloud provider.
________ is a strategy where applications are moved to the cloud in their existing form, with the intention of making modifications at a later stage.
- Re-architecting
- Re-factoring
- Re-hosting
- Re-platforming
In the "re-hosting" strategy, applications are migrated as-is to the cloud, with modifications planned for a later phase.
Storage virtualization involves:
- Abstracting physical storage
- Emulating hardware
- Enhancing software performance
- Running multiple OSes
Storage virtualization abstracts physical storage devices to create a logical pool, simplifying management and improving utilization.
CRM software primarily focuses on:
- Document Editing
- Financial Accounting
- Managing Customer Relationships
- Video Editing
Customer Relationship Management (CRM) software primarily focuses on managing and improving interactions and relationships with customers.
A company is looking to securely store sensitive data in the cloud. They want to ensure that even if someone gains access to the data, it would be unreadable. Which technology would you recommend they implement?
- Access Control Lists (ACL)
- Digital Signatures
- Encryption
- Intrusion Detection System (IDS)
Encryption is the best technology to ensure data security in the cloud. It renders data unreadable to unauthorized users even if they gain access to it.
________ is a cloud computing service where the cloud vendor provides the hardware and software tools needed for application development to users over the internet.
- Database as a Service (DBaaS)
- Infrastructure as a Service (IaaS)
- Platform as a Service (PaaS)
- Software as a Service (SaaS)
Platform as a Service (PaaS) offers users the hardware, software, and tools needed for application development. It simplifies the development process by providing a platform for building, testing, and deploying applications without the complexity of managing infrastructure.
Organizations that require a secure and isolated environment for their critical applications often opt for a ________ cloud.
- Community
- Hybrid
- Private
- Public
Private clouds are ideal for organizations that need to maintain strict control and security over their data and applications. They are isolated and hosted on a dedicated network, offering a high degree of customization and security, making them suitable for critical applications.
Which cloud service model is best suited for developers who want to focus on code without worrying about the underlying infrastructure?
- Function as a Service (FaaS)
- Infrastructure as a Service (IaaS)
- Platform as a Service (PaaS)
- Software as a Service (SaaS)
Platform as a Service (PaaS) is the best fit for developers who want to concentrate on coding without managing the infrastructure. PaaS provides the development environment, runtime, and other tools needed for application development, abstracting away the underlying servers and infrastructure concerns.
Middleware often acts as a bridge between:
- Clients and databases
- Databases and files
- Hardware and software
- Users and servers
Middleware often acts as a bridge between hardware and software, ensuring seamless communication and interaction between these two components.
Which of the following is NOT typically a function of middleware?
- Data Storage and Retrieval
- Message Routing
- Security
- User Interface
Middleware primarily handles tasks like data storage and retrieval, security, and message routing. User interface management is typically outside the scope of middleware.
