AWS's primary service for object storage is:
- Amazon DynamoDB (NoSQL Database)
- Amazon EC2 (Elastic Compute Cloud)
- Amazon RDS (Relational Database Service)
- Amazon S3 (Simple Storage Service)
Amazon S3 (Simple Storage Service) is AWS's primary service for object storage. It provides scalable, durable, and highly available object storage in the cloud, commonly used for data and file storage.
Paravirtualization differs from full virtualization in that:
- It doesn't isolate workloads.
- It doesn't require a hypervisor.
- It doesn't support live migration.
- It requires modification of the guest OS.
Paravirtualization requires modifying the guest OS to improve performance, whereas full virtualization does not require such modifications.
In the context of cloud deployment models, which type of cloud typically has a higher upfront cost due to infrastructure investments?
- Community Cloud
- Hybrid Cloud
- Private Cloud
- Public Cloud
Private Clouds are typically associated with higher upfront costs because organizations need to invest in their infrastructure and management. Public clouds share resources and costs with multiple organizations.
What distinguishes a hybrid cloud from a multi-cloud?
- Hybrid uses physical servers
- Mixing public and private clouds
- Multi-cloud combines different cloud service providers
- The use of multiple private clouds in a hybrid setup
A hybrid cloud combines public and private cloud infrastructure, whereas a multi-cloud involves using services from different cloud providers, which may not be public-private mix.
The cloud infrastructure that is provisioned for open use by the general public is termed as ________.
- Community
- Hybrid
- Private
- Public
The cloud infrastructure designed for use by the Public is accessible by individuals, businesses, and organizations. It is hosted and managed by a cloud service provider and offers services on a pay-as-you-go basis. Public clouds are shared resources, providing flexibility and cost-effectiveness.
A multinational corporation is looking for a cloud solution that can be accessed from any of their global locations, without any restrictions on the devices used. Which characteristic of cloud computing best fits their needs?
- Accessibility
- Elasticity
- On-Demand Usage
- Scalability
Accessibility is a key aspect of cloud computing that ensures that resources are available from anywhere, on any device, making it suitable for global use.
In which cloud model does an organization exclusively own and maintain the cloud infrastructure?
- Community Cloud
- Hybrid Cloud
- Private Cloud
- Public Cloud
In a "Private Cloud" model, an organization exclusively owns and maintains the cloud infrastructure. It is not shared with other organizations and is hosted on-premises or in a dedicated environment. This provides greater control and security but requires more resources.
In a microservices architecture, each service should ideally be:
- Loosely Coupled
- Stateful
- Stateless
- Tightly Coupled
In a microservices architecture, services should be loosely coupled to allow for flexibility, independent scaling, and easy replacement without affecting the entire system.
One potential drawback of SaaS for some businesses is the potential lack of ________ over the software's functionality and data.
- Accessibility
- Control
- Cost
- Customization
Control is a critical aspect that some businesses may worry about in a SaaS model, as they have limited control over the software's behavior and data.
A company is looking to migrate their on-premises SQL Server databases to the cloud. They are already using Microsoft products extensively. Which CSP and specific service would be a natural fit for them?
- Amazon Web Services (AWS) - RDS
- Google Cloud Platform (GCP) - BigQuery
- IBM Cloud - Db2 Warehouse on Cloud
- Microsoft Azure - Azure SQL Database
Microsoft Azure offers Azure SQL Database, a managed SQL database service that seamlessly integrates with Microsoft products, making it a natural fit.
