(DEV201) AWS SDK For Go: Gophers Get Going with AWS
•
2 recomendaciones•2,058 vistas
The AWS SDK for Go is now live and ready for developers to build productive applications with using the Go programming language. This session will show you how to get started using the AWS SDK for Go. We’ll introduce the best practices for how to use the SDK, and how it integrates with your Go application. We will explore an example application which uses async programming with Amazon S3 and Amazon SQS to distribute tasks across multiple concurrent goroutines, and use Amazon Elastic Beanstalk to deploy and scale the application.

- 7. What to expect from the session • Get started with the AWS SDK for Go • Build concurrent application with the SDK • Deploy and scale the application
- 8. Go get the AWS SDK for Go • Get the SDK • go get -u github.com/aws/aws-sdk-go/... • Tagged release versioning • e.g. “v0.9.9”
- 9. Structure of AWS SDK for Go • import "github.com/aws/aws-sdk-go/aws" • Utilities tools • Configuration • import "github.com/aws/aws-sdk-go/service/s3" • Service client • API operations • API request/response structs
- 10. Configuration for AWS SDK for Go • Requires region and AWS credentials. • Service clients are given a configuration that is merged with the default configuration. Specify only what you need. • Create unique service client instances with different configurations.
- 11. Configuration: credentials • NEVER put AWS credentials in your code. • Credentials provider chain: 1. Environment variables 2. Shared credentials file 3. EC2 instance profile credentials
- 12. Credentials: shared credentials file • Default file, ~/.aws/credentials • Shared by all SDKs and AWS CLI • Multiple sets of credentials as profiles • AWS_PROFILE specifies profile
- 13. ~/.aws/credentials [default] aws_access_key_id = ACCESS_KEY_ID aws_secret_access_key = SECRET_ACCESS_KEY_ID [prod] aws_access_key_id = ACCESS_KEY_ID aws_secret_access_key = SECRET_ACCESS_KEY_ID

- 15. What to expect from the session • Get started with the AWS SDK for Go • Build concurrent application with the SDK • Deploy and scale the application
- 16. Word frequency • Analyze files and determine top 10 most common words. • Persist the data and write to a queue for further processing. • Goals: concurrent, durable, and scalable. https://github.com/awslabs/aws-go-wordfreq-sample
