##How to make SSL work on Microsoft Azure

##### Microsoft Azure requires a password-protected PFX file (containing the public key for your domain including any and all intermediate CA certs) in order to support HTTPS (TLS - SSL) support on your Azure hosted websites. Here's how to get it working with certificates from GeoTrust / RapidSSL (and others too probably).

__1) Create CSR__

Create a CSR-file and private key with OpenSSL and upload it to your CA:
```
openssl req -new -nodes -keyout yourprivatekey.key -out server.csr -newkey rsa:2048
```

Create a dedicated ZFS docker pool with deduplication disabled in case of dedup enabled on your system:

zfs create -o mountpoint=/var/lib/docker -o dedup=off rpool/docker

Sometimes, you don't want ZFS for docker storage. ZFS can be sadly quite painful with Docker in Docker and similar scenarios. It might be best to avoid the problem by creating a volume in your ZFS pool, formatting that volume to ext4, and having docker use "overlay2" on top of that, instead of "zfs".

zfs create -s -V 30G rpool/docker

mkfs.ext4 /dev/zvol/rpool/docker

NGINX Tuning For Best Performance

For this configuration you can use web server you like, i decided, because i work mostly with it to use nginx.

Generally, properly configured nginx can handle up to 400K to 500K requests per second (clustered), most what i saw is 50K to 80K (non-clustered) requests per second and 30% CPU load, course, this was 2 x Intel Xeon with HyperThreading enabled, but it can work without problem on slower machines.

You must understand that this config is used in testing environment and not in production so you will need to find a way to implement most of those features best possible for your servers.
