Database Design

The vector stencils library "AWS Database" contains 31 Amazon Web Services database icons: Amazon DynamoDB icons, Amazon ElastiCache icons, Amazon Relational Database Service icons, Amazon Redshift icons, AWS Database Migration Service icons, Amazon DynamoDB Accelerator icon.
Use it to draw Amazon Web Services architecture diagrams with ConceptDraw PRO diagramming and vector drawing software.
"Amazon DynamoDB is a fast and flexible NoSQL database service... It is a fully managed cloud database and supports both document and key-value store models." [aws.amazon.com/ dynamodb/ ]
"ElastiCache is a web service that makes it easy to deploy, operate, and scale an in-memory cache in the cloud." [aws.amazon.com/ elasticache/ ]
"Amazon Relational Database Service (Amazon RDS) makes it easy to set up, operate, and scale a relational database in the cloud. ... Amazon RDS provides you six familiar database engines to choose from, including Amazon Aurora, Oracle, Microsoft SQL Server, PostgreSQL, MySQL and MariaDB." [aws.amazon.com/ rds/ ]
"Amazon Redshift is a fast, fully managed, petabyte-scale data warehouse that makes it simple and cost-effective to analyze all your data using your existing business intelligence tools." [aws.amazon.com/ redshift/ ]
"AWS Database Migration Service helps you migrate databases to AWS easily and securely." [aws.amazon.com/ dms/ ]
The AWS icons example "Design elements - AWS Database" is included in the AWS Architecture Diagrams solution from the Computer and Networks area of ConceptDraw Solution Park.

This Azure cloud architecture pattern diagram template was created on the base of figure in the article "External Configuration Store Pattern" from the Microsoft Developer Network (MSDN) website.
"External Configuration Store Pattern.
Move configuration information out of the application deployment package to a centralized location. This pattern can provide opportunities for easier management and control of configuration data, and for sharing configuration data across applications and application instances. ...
The majority of application runtime environments include configuration information that is held in files deployed with the application, located within the application folders. In some cases it is possible to edit these files to change the behavior of the application after it has been deployed. However, in many cases, changes to the configuration require the application to be redeployed, resulting in unacceptable downtime and additional administrative overhead. ...
Store the configuration information in external storage, and provide an interface that can be used to quickly and efficiently read and update configuration settings. The type of external store depends on the hosting and runtime environment of the application. In a cloud-hosted scenario it is typically a cloud-based storage service, but could be a hosted database or other system.
The backing store chosen for configuration information should be fronted by a suitable interface that provides consistent and easy to use access in a controlled way that enables reuse. Ideally, it should expose the information in a correctly typed and structured format. The implementation may also need to authorize users’ access in order to protect configuration data, and be flexible enough to allow multiple versions of the configuration (such as development, staging, or production, and multiple release versions of each one) to be stored."
