HTTP Streaming (or Chunked vs Store & Forward)

The standard way of understanding the HTTP protocol is via the request reply pattern. Each HTTP transaction consists of a finitely bounded HTTP request and a finitely bounded HTTP response.

However it's also possible for both parts of an HTTP 1.1 transaction to stream their possibly infinitely bounded data. The advantages is that the sender can send data that is beyond the sender's memory limit, and the receiver can act on

Cleanroom

Do you sometimes want to run performance benchmarks, stress/load tests, or security vulnerability probes against a shared integration environment, or even a production environment?
Do you worry about polluting these environments, or not leaving any audit trail when things go wrong?

Here are a couple scripts to setup, and later teardown, a cleanroom environment (user, org, space, quota) for doing just these kinds of experiments.

Example

This guide reflects all the steps needed to get Vmware integrated within OpenStack (VMware vCenter version: 5.1 and OpenStack Liberty)

Official documentation available:

http://docs.openstack.org/liberty/config-reference/content/vmware.html http://docs.openstack.org/liberty/config-reference/content/list-of-compute-config-options.html#config_table_nova_vmware

Just follow the steps available in the links above.

BOSH Links: Why and How

Audience: anyone in the BOSH ecosystem, whether you work on something open-source or proprietary

"BOSH Links" is a feature which simplifies how data is shared between BOSH-deployed jobs that need to collaborate with one another (e.g. a web server and its backing database). Like many BOSH things, the whole "BOSH Links" thing can seem counter-intuitive at first, and it may not be clear why things are the way they are. This note hopes to show some of the powerful benefits of BOSH Links, and provide examples and explanations that make things more intuitive.

Why?
BASIC: A simple problem statement
BASIC: Putting the puzzle pieces together
ADVANCED: But what about...
