In AWS, _______ is an orchestration service for automating deployment, scaling, and operations of application containers.
- EC2 Container Service
- ECS Fargate
- Elastic Beanstalk
- Lambda
AWS Elastic Beanstalk is an orchestration service that automates deployment, scaling, and operations of applications.
For a company migrating to a microservices architecture, how should they approach testing for each individual service?
- Isolated testing for each service
- Only perform unit testing
- Skip testing for services
- Testing all services together
Testing each microservice in isolation is crucial to ensure that they function correctly and maintain independence in a microservices architecture.
For a SOAP service that requires dynamic discovery of other services, what technology is typically employed?
- Representational State Transfer (REST)
- Simple Object Access Protocol (SOAP)
- Universal Description, Discovery, and Integration (UDDI)
- Web Services Description Language (WSDL)
Universal Description, Discovery, and Integration (UDDI) is a technology commonly employed for dynamic service discovery in SOAP-based architectures. UDDI provides a standard way for services to be published and discovered dynamically, allowing SOAP services to locate and interact with other services in a flexible and scalable manner.
WSDL documents are formatted in which language?
- HTML
- JSON
- Java
- XML
WSDL documents are formatted in XML (eXtensible Markup Language), providing a standardized way to describe web services.
In which type of web service architecture is UDDI most commonly used?
- Remote Procedure Call (RPC)
- Representational State Transfer (REST)
- Service-Oriented Architecture (SOA)
- Simple Object Access Protocol (SOAP)
UDDI is most commonly used in Service-Oriented Architecture (SOA), providing a directory for businesses to publish and discover services in a standardized way.
In a cloud-native approach, _______ helps in defining and managing complex architectures.
- Infrastructure as Code (IaC)
- Manual configuration
- Static resource management
- Traditional deployment
In a cloud-native approach, Infrastructure as Code (IaC) is used to define and manage complex architectures, providing agility and scalability.
In AWS, what is the primary function of Elastic Load Balancing?
- Configuring network security groups
- Deploying and managing virtual machines
- Distributing incoming application traffic across multiple targets
- Storing and retrieving data in the cloud
Elastic Load Balancing in AWS is used to distribute incoming application traffic across multiple targets, ensuring high availability and fault tolerance.
Web services must adhere to _______ to ensure data privacy and security.
- HTTP
- JSON
- SSL/TLS
- XML
Web services must adhere to SSL/TLS to ensure data privacy and security through secure communication.
What is the main difference between SSL and TLS protocols in web services?
- SSL is for secure websites, and TLS is for non-secure websites
- SSL is newer than TLS and has more features
- TLS is the successor of SSL and provides better security
- There is no difference; they are used interchangeably
TLS is the successor to SSL and provides improvements in security. It's important to use TLS for secure data transmission in modern web services.
How does versioning in SOAP differ from RESTful services?
- RESTful services do not support versioning
- RESTful services often rely on URI versioning
- SOAP typically uses explicit versioning in the message format
- SOAP uses header information for versioning
SOAP and RESTful services differ in versioning approaches. SOAP often uses explicit versioning in the message format, while RESTful services commonly employ URI versioning.
