August DevOps Galway

For our August meetup we are delighted to be joined by Patryk Hes (Google), and Karl Kyck & Alan Carolan (Liberty IT).

Patryk Hes (Google)
Patryk is a Site Reliability Engineer at Google in Dublin. His specialties are large-scale data storage systems and infrastructure with a focus on cold storage. Before delving into the world of distributed systems, he fine-tuned the search engine of paperity.org, an Open Science scientific papers' aggregator. He also developed front-end code for quantumgame.io -- if you like physics, you should try it! During his university time he conducted several computer science workshops for high school students (including topics like machine learning, text mining, and writing distributed systems in Python). In his spare time he is tinkering with music synthesizers, 3D printers, and brewing beer at home.

Presentation: Data Integrity
When designing, building, and maintaining a computer system, one can ask the following questions: "Is my data safe from being accidentally deleted or corrupted? How do I ensure data integrity in the long term?"

The main goal of the presentation is to analyze several data integrity pitfalls and review recommended solutions, so that you can construct a data integrity strategy appropriate for your service and your DevOps team.

Karl Kyck & Alan Carolan (Liberty IT)
Karl Kyck is a Senior Portfolio Architect at Liberty IT and is the exec sponsor of Green Scene, Liberty IT’s sustainability working group. He specialises in platform architecture and design, software testing practices, and software delivery optimisation. Karl creates value for the organisation by building differentiating capabilities, and leveraging cloud providers and SaaS offerings to offload undifferentiating work.

Alan Carolan is a Senior Security Analyst at Liberty IT and a member of LIT’s Green Scene group. A career change in 2017 brought a new challenge as he moved into the Cybersecurity space. Working in the Cybersecurity Operations Centre, Alan is primarily an end user of cloud based services & tooling and is aware of the impact of such services within LIT. Working closely with the SOC aligned development team, an awareness exists when it comes to queries associated with daily incident response and related cloud based analysis activities.

Presentation
Software development and leveraged IT infrastructure has a significant impact on the environment in terms of carbon emissions and water usage. For example in 2022 datacentres in Ireland consumed 18% of the total energy consumption of the country. That number is only due to increase. As software engineers our choices matter in how we work and build applications and the effect that has on the environment.
In this talk we will cover practical ways we can reduce our impact on the environment and develop applications more sustainably. What is more, sustainable software engineering promotes good engineering practices and makes us better developers. This helps us strengthen the companies we work for, our employment status, marketable skills, and career prospects.
We will also chat about how Liberty has embraced the cloud, benefiting from cost reduction and cloud provider sustainability optimisations, and how we are embarking on our intentional sustainable software engineering journey.

Pizzas & Refreshments
Pizzas on the night are kindly sponsored by Liberty IT.

Following the presentations we will relocate to a local bar for some post meetup drinks and chat.
