Why to open ports when you can stream the data to Essbase (OAC) over HTTPS?

Migrating to cloud is sometimes hard when few things are on premise and few are moved to cloud. It becomes harder when cloud is connecting back to on premise systems. Say we have a large warehouse on premise and some application is on cloud and now cloud application wants to connect to this warehouse.
Some cloud providers came with *** Direct Connect, few came with **** Connect.
We may have to open the system and ports to public network and maintain those ports backed by strong IT team. Well, good luck with that!

One other approach could be to upload the huge files and process those files on cloud. Not a bad approach security wise but time consuming.

What could be really cool is someone comes up with a solution where we do not have to open the ports but we can stream on premise data to the cloud using industry standard HTTPS.
Wish listened! OAC- Essbase  streaming command line will allow us to do that as it comes with a tiny stream loader for a giant problem.
Let's try it out...

Playing with essbase ad hoc analysis using command line

If you are not familiar with cURL, JSON and REST, please read my earlier blog. Initial section of it has few links to quick start.

In this blog, we are going to play with a grid using command line. Wait! Is this even possible?
Let's try...

Introduction to Cube Designer - Files


OAC-Essbase has introduced a new platform concept called a catalog. The catalog is an area of storage within the cloud for both Essbase artifacts and end user artifacts. The catalog uses the OAC-Essbase security to restrict access.

Can Python digest a cube?


Then, I drew the inside of the boa constrictor, so that the grown-ups could see it clearly. They always need to have things explained.
But let's put elephants and boa constrictors aside. The more important question would be -- Can Python digest a cube? Nowadays even kids in elementary schools do python, so I thought it would be useful to show how Python code can call OAC Essbase REST APIs. Let's try to list files under /gallery/Cubes directory in the Essbase catalog.

Introduction to outline editing using JSON and REST apis

In this blog, we will cover how we can automate the outline editing using simple JSON file and REST apis.

Read more about JSON here: https://www.json.org/
and REST apis here: https://en.wikipedia.org/wiki/Representational_state_transfer

We will use cURL for executing the outline REST. cURL is a command line library to execute HTTP requests.
https://en.wikipedia.org/wiki/CURL

cURL is installed by default on the Linux systems but on windows, you have to download and install it before trying the examples. https://curl.haxx.se/download.html

If you want to try any REST clients like POSTMAN etc., you can skip the cURL installation.
