In this talk we will look at the history of how the impact of Cloud on Open Source changed through the years\, examine the current state as well as make a case for a particular way to use Cloud and Open Source Together. If you cherish the values of Open Source – you will do well by using Cloud as Commodity Infrastructure Provider and run Open Source Software on top of it. Consider Kubernetes in particular as your API of choice with its ubiquitous availability among all major public cloud providers and private cloud software vendors. We will show what while this ecosystem may not be as mature as proprietary solution from cloud vendors it is moving rapidly and becoming a great fit for more and more situations. \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n About the Author\n \n \n \n \n \n Peter Zaitsev\, Founder at Percona\, OpenSource Advocate \n \n \n \n \n \n As one of the foremost experts on Open Source strategy and databases optimization\, Peter leveraged both his technical vision and entrepreneurial skills to grow Percona from a two-person shop to one of the most respected open source companies in the business.

Peter is a co-author of High Performance MySQL: Optimization\, Backups\, and Replication\, one of the most popular books on MySQL performance. \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n Talk description\n \n \n \n \n \n MongoDB\, a widely used database\, has garnered both love and hate from its users across different industries due to its ease of use. However\, it is no longer open source\, faces licensing issues\, and requires additional resources and knowledge to run. Is there a viable alternative? Can we move existing MongoDB workloads to Postgres without any application-level changes? How can we ensure MongoDB users can continue to use their tools and frameworks? In this talk\, we will discuss the current state of document databases and why there is a need for a new open source standard. We propose that Postgres should serve as the database backend for this standard. We will also demonstrate how to equip your Postgres database with FerretDB\, enabling it to handle MongoDB workloads. Finally\, we will showcase some MongoDB tools that can be used to manage the database just like if it would be MongoDB. This use case connects Postgres with a different community and workloads. \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n Talk description\n \n \n \n \n \n The cost of running a growing enterprise-grade MongoDB environment on the Cloud can quickly get out of control. To make things worse\, there are multiple traps awaiting. Factors and settings that initially do not seem important\, at scale can significantly impact your spending. In this session\, we will discuss the open source options available for running MongoDB workloads in a Cloud Native manner\, and you will learn how to build a scalable\, cost-effective MongoDB deployment leveraging open source components and K8s. \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n Talk description\n \n \n \n \n \n ML for observability can be challenging\, given the uniqueness of each workload. However\, we can leverage ML to detect individual component anomalies\, even if they are sometimes noisy/imprecise. At Netdata\, we use ML models to analyze the behavior of individual metrics. These models adapt to the specific characteristics of each metric\, ensuring anomalies can be detected accurately\, even in unique workloads. The power of ML becomes evident when these seemingly noisy anomalies converge across various services\, serving as indicators of something exceedingly unusual. ML is an advisor\, training numerous independent models for each individually collected metric to achieve anomaly detection based on recent behavior. When multiple independent metrics exhibit anomalies simultaneously\, it is usually a signal that something unusual is occurring. This approach to ML can be instrumental in uncovering malicious attacks and predicting combined failures across seemingly unrelated components. \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n Talk description\n \n \n \n \n \n PostgreSQL has been providing OO features since the very early versions\, thus making it one of the first ORDBMS systems. To understand OO in databases we may think of tables high in a hierarchy as abstract classes/interfaces in java\, while tables that are low in the hierarchy can be parallelized with implementation classes with no subclasses. The technology providing OO in PostgreSQL is called : inheritance. Inheritance in PostgreSQL traditionally has had two major uses : a) partitioning\, before native declarative partitioning was provided after v10\, and b) for object oriented design on the data model. Logical partitioning or its reverse : consolidation is a very real business need\, and can be applied to the case of departmentalization of data and multi-tenancy\, while still retaining the ability to view the whole organization as a whole. In this talk we will present some scenarios where inheritance can be a very elegant and performant solution for situations like the one described. \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n Talk description\n \n \n \n \n \n MySQL is a popular relational database management system that millions of websites and applications use. Its performance is critical to the overall performance of these applications. However\, MySQL performance tuning can be a challenging task for developers. This talk will discuss the importance of MySQL performance tuning\, approaches to tuning performance\, and how AI can help developers simplify this task. \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n Photos from event\n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n Go to Photo Album\n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n Our Partner\n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n FerretDB is a truly open source alternative to MongoDB\, built on Postgres\, and released under Apache 2.0. FerretDB turns Postgres into a MongoDB-compatible database. Run MongoDB workloads (JS frameworks\, tools\, drivers) on Postgres\, just like if you would run them on MongoDB. Besides Postgres\, FerretDB also supports SQLite as a database backend. \n \n Visit website URL:https://percona.university/event/percona-university-athens-open-source-databases-meetup-2023/ LOCATION:Impact Hub Athens\, 28 Karaiskaki\, Athens\, 10554\, Greece ATTACH;FMTTYPE=image/png:https://percona.university/wp-content/uploads/2024/03/Percona-University-Athens-Sponsor-copy.png END:VEVENT BEGIN:VEVENT DTSTART;TZID=UTC:20240420T093000 DTEND;TZID=UTC:20240420T150000 DTSTAMP:20260411T141321 CREATED:20240318T184349Z LAST-MODIFIED:20250313T154320Z UID:10000005-1713605400-1713625200@percona.university SUMMARY:Percona University Limassol\, Cyprus 2024 DESCRIPTION: URL:https://percona.university/event/percona-university-limassol-cyprus-2024/ LOCATION:Synergy Conference Center\, M2RM+VRQ\, Λυκάβου\, Limassol\, 3086\, Cyprus ATTACH;FMTTYPE=image/png:https://percona.university/wp-content/uploads/2024/03/Percona-University-Limassol-copy.png END:VEVENT BEGIN:VEVENT DTSTART;TZID=Europe/Paris:20250526T090000 DTEND;TZID=Europe/Paris:20250526T173000 DTSTAMP:20260411T141321 CREATED:20250313T155418Z LAST-MODIFIED:20250515T124351Z UID:10000010-1748250000-1748280600@percona.university SUMMARY:Percona University Milan\, Italy DESCRIPTION:What Is Percona University?\nPercona University is a global series of free educational events dedicated to Open Source and open-source database technology.
