- Amazon Web Services (AWS)
- Google Cloud Platform (GCP)
- IBM Cloud (IBM)
- Microsoft Azure (Azure)
Microsoft Azure, often referred to as Azure, offers the Azure Kubernetes Service (AKS) for container orchestration. Azure is a leading cloud provider known for its container management services.
In Azure Functions, ________ is the feature that lets you execute a small piece of code (or function) in response to event-driven HTTP requests.
- Azure Functions
- Azure Logic Apps
- Azure Queues
- Azure Triggers
Azure Functions allows you to execute code in response to event-driven HTTP requests. Logic Apps, Queues, and Triggers are not the feature itself.
What is the main function of a Dockerfile?
- Building Docker images
- Defining Kubernetes pods
- Managing Docker networks
- Running Docker containers
A Dockerfile is used to define the instructions to build a Docker image. It includes everything needed to create the image, such as base image, dependencies, and application code.
A software company has a team of developers who want to quickly build and deploy applications without getting involved in infrastructure management. They are looking for a cloud service model that provides development tools and database management systems. Which service model should they consider?
- Function as a Service (FaaS)
- Infrastructure as a Service (IaaS)
- Platform as a Service (PaaS)
- Software as a Service (SaaS)
The software company should consider the Platform as a Service (PaaS) model. PaaS provides development tools, databases, and application deployment without managing the underlying infrastructure. It's ideal for rapid application development.
An organization wants to build a lightweight API that scales automatically and only incurs costs when it's actually used. They are deeply invested in Microsoft technologies. Which service would best fit their requirements?
- Azure Functions
- Azure Logic Apps
- Azure SQL Database
- Azure Virtual Machines
Azure Functions is a serverless compute service in the Microsoft Azure ecosystem, ideal for building lightweight APIs that automatically scale and charge only for actual usage. It's designed for cost-efficient, event-driven workloads.
When integrating with a cloud-based data lake, which feature of Google BigQuery is crucial for real-time analytics?
- In-Memory Database and Strong Security
- Multi-Model Support and Serverless Processing
- Real-Time Data Streaming and Analytical Views
- Search Indexing and Complex Query Optimization
Real-Time Data Streaming and Analytical Views in Google BigQuery enable continuous, real-time analysis of data from a data lake, a crucial feature for real-time analytics.
A cloud provider is designing a new service. They want to ensure that even if some servers go down, the service remains uninterrupted. This would involve intricate design and management of which part of the cloud?
- Auto-scaling groups
- Disaster recovery configurations
- High availability zones
- Load balancers
To ensure service continuity despite server failures, designing and managing high availability zones is crucial for redundancy and fault tolerance.
A company using a CRM tool over the internet without installing any software on their local machines is an example of:
- IaaS
- On-premises software
- PaaS
- SaaS
This is a classic example of SaaS (Software as a Service), where the CRM tool is accessed over the internet without local software installation. SaaS is one of the cloud computing service models.
In AWS Lambda, the concept that ensures the environment variables, associated dependencies, and the runtime settings are packaged together is known as:
- Configuration Bundle
- Containerization
- Execution Context
- Runtime Environment
In AWS Lambda, the 'Configuration Bundle' concept ensures that environment variables, dependencies, and runtime settings are bundled together for execution. This is vital for maintaining consistency and reliability.
