Open Infra Days
17.09.2020 in Olten
We are pleased to present you the new edition of our Open Infra Days. This year, our Open Source-oriented event will include two technical streams in which various topics such as Suse Linux Enterprise systems, AWS SSM, PostgreSQL, JenkinsX or how to build a modern Cloud infrastructure will be presented.
AGENDA & SESSION DESCRIPTION
Stream 1 (in English)
With today’s Dev/Ops approach, databases need to be provisioned and cloned instantly.
Developers often need new Postgres instances for development and testing purposes against a defined version. These must be readily available for testing and validation procedures. By combining PostgreSQL with the BRTFS filesystem on SUSE Linux Enterprise systems, this requirement becomes a no brainer.
This session will guide you through rapid provisioning and cloning using BRTFS subvolumes in an automated way. Wrap that into Ansible playbooks and database instances can be provisioned and cloned by everyone.

Are legacy applications ready for Cloud Native as in Production? Are they truly suitable? Does the use of JenkinsX EcoSystem really help? During this talk we will share our feedback based on the experience of implementing Jenkins X as a CI/CD platform in the pharma industry.
- Arnaud Berbier, Platform Solution Architect and Senior Consultant at dbi services
It is expected that 75% of databases in the world will run in the Cloud by 2022. In the meanwhile, we have noticed that we have exactly the same infrastructure challenges and performance issues with databases in the Cloud as we had 20 years ago with those on premises. At that time, we had to carefully select the resources, especially the disks, for the database systems to be as efficient as possible. Today with SSDs, a lot of memory and Gigabyte network connectivity, this careful selection of resources is less important. In the Cloud, on the other hand, we must again make a thorough check of the assigned resources to control costs and performances. In this session, we’ll look at the best practices on how to build a modern Cloud Infrastructure that fits for the main public Cloud providers. We will also have a look at some key points to consider when choosing resources in the Cloud.
- Hervé Schweitzer, Chief Technology Officer (CTO) and Principal Consultant at dbi services
Stream 2 (in German)
Server patching is time consuming and subject to human error. We are also often confronted with the customers’ expectations in terms of timing. This can be simplified by using AWS SSM to patch your Windows / Linux (RHEL, Amazon, Linux, Ubuntu, CentOS) onprem and EC2 Instances.
We will have a look at both instances and study their respective benefits and drawbacks during an implementation at the customer’s.

Traditionally PostgreSQL stores relations in a format called ” heap “. This comes with advantages, but also with drawbacks. One of the downsides is that every PostgreSQL DBA needs to deal with bloat at some point in time as updates generate new rows in PostgreSQL.
Zheap promises to eliminate most of this bloat. In addition, it claims to be superior for certain kinds of workloads by introducing undo segments. In various demos, we will go through the architecture of zheap, highlight its advantages and then do some tests, thus comparing heap and zheap.
