The Best of the Week (Oct 3): Cloud Zone

Make sure you didn't miss anything with this list of the Best of the Week in the Cloud Zone (Oct 3 to Oct 9). Here they are, in order of popularity:

1. How Do Cloud Developers Know When an App is "Done"? (JavaOne 2014)

This slideshow from a recent JavaOne session by Daniel Bryant was posted that elaborates on some of the obstacles for developing in the cloud. Bryant is a principal consultant at OpenCredo, and he has a lot to say about cloud development, useful tools, and helpful techniques.

2. CloudStack Simulator on Docker

Docker is a lot of fun, one of its strength is in the portability of applications. This gave me the idea to package the CloudStack management server as a docker image. CloudStack has a simulator that can fake a data center infrastructure.

4. Aggregations in Distributed In-Memory Grids

Today we see more applications that are no longer built on relational databases but instead on distributed environments. This occurs because they need to be scalable, highly available and be able to provide high throughput and low latency that cannot be achieved with older relational databases.

5. How to Allow Only HTTPS on an S3 Bucket

It is possible to disable HTTP access on S3 bucket, limiting S3 traffic to only HTTPS requests. The documentation is scattered around the Amazon AWS documentation, but the solution is actually straightforward.
