1. What are some of the important factors to consider when choosing an AWS region?
2. How can you accelerate the delivery of content across the globe if your application is deployed in a single AWS region?
3. What are the most common tools that allow you to interact with AWS services?
Answers
1. Answer: When you are choosing a region, usually the most important consideration would be the data residency or sovereignty, which determines if the data can even reside in the selected region. Another factor to consider would be proximity to the users. A region that is closer to the users will allow for a much better experience due to lower latency for each request. You should also consider if the services you are intending to use are available in the region. Finally, consider the region with the lowest price for the service. Regions are located in different areas where costs of operation might differ, which eventually leads to different prices for services.
2. Answer: AWS operates a content delivery network (CDN) that operates in all edge locations. The CDN can help you deliver the content to users across the globe with the lowest latency possible.
3. Answer: The management console, a graphical user interface that is accessible from anywhere using a browser, the AWS command-line interface (CLI), and the AWS software development kits (SDKs).
Amazon Web Services (AWS) was launched in 2006 by Amazon and is widely recognized as the first true public cloud computing platform. The company was spun out of the knowledge that the IT specialists in the company have gained while running the amazon.com platform. The services that have been created over time allow you to deploy applications with extremely high availability, unlimited performance, and unbeatable reliability at any scale with the most modern features. Lots of effort has gone in to providing capabilities and features that make management, operations, and automation of the environment a breeze.
