Google Bare Metal – how to start.

In the previous post I put some of my thoughts on why you would use the Google Bare Metal Service (BMS) and my first impression about it. In this post I want to talk about the first steps and how you can start to work with the Google Bare Metal Service (BMS).

To put your hands on BMS you need to contact your Google Cloud sales representative and order it. It means you need to know to some extent your requirements and prepare for that. The major preparation steps are described in the Google documentation and here I will try to go through some of them.

The first main step is to outline your architecture and identify the region for the BMS. The service is a region extension and it means it is connected to your regional Google cloud infrastructure by high speed low latency network interconnect. It makes sense to place it where the most of your applications and users are going to be. For example, in my case I’ve chosen the us-west2 (Los Angeles) and it was aligned with my main test app servers and provided the best response time. The 64 bytes ping from an app server in the same region was 0.991 ms on average.

Google Bare Metal for Oracle.

Since the first days of working in the Google public cloud there have been debates about the possibility to move an Oracle workload to GCP. The major concerns were coming not from the technical challenges but rather from Oracle’s licensing policies and guidelines. In the famous Oracle’s document about licensing Oracle software in the public cloud it was stated – “This policy applies to cloud computing environments from the following vendors: Amazon Web Services – Amazon Elastic Compute Cloud (EC2), Amazon Relational Database Service (RDS) and Microsoft Azure Platform (collectively, the ‘Authorized Cloud Environments’)”. So the Google Cloud was not listed as an ‘Authorized Cloud Environment’ and it was unclear how to apply the Oracle licensing there. I believe it will be sorted in time but in the meanwhile as a solution Google presented a Bare Metal Service as the platform for Oracle workload.

From Oracle to Google Big Query by Kafka

Last week while checking my twitter feed I found a tweet from Confluent with an announcement about a new Kafka connector for Oracle database as a source. We had an Oracle connector before but it was working scanning the source tables and, as a result, adding a load to the source database. But that one was different and we got a connector which could get the changes from Oracle redo logs. I started to test it using my Kafka dev environment in the Google Cloud and one of my sandbox databases in the Oracle cloud. Here I would like to share how to start to test it and my very first experience with the tool.
