AWS meetups are back in town! This chapter is the 1st one this year and dedicated to **S3.** But we look on the storage from completely different angles: **From Developer's to Penetration and Security perspective.** More info soon, and the meantime we reveal topics, and... 🗓 **Save the Date**: Mark your calendar 🍕 + 🍺 = Let's gather around pizza and beer at **Hevre** or Watch the stream on [YouTube (Link)](https://youtube.com/live/Tx7lmDVTVKo) Hosted by: **Maciej Lelusz**, AWS Hero AWS Community Builders: **Maria Kmita & Pawel Kusinski** 🎤 **Speakers**: 〰️ *„*"Optimizing S3: A Million-Dollar FinOps Journey" **Avihay Tsayeg,** Senior Staff DevOps Engineer, Cloudinary 〰️ *„UnS3cure - Buckets full of holes"* **Paweł Kusiński,** Penetration Tester and Security Researcher 💡 Details about Speakers & Talks💡 **Avihay Tsayeg:** joined Cloudinary five years ago and is a key member of the Infrastructure group, where he leads the FinOps domain. With over 20 years of experience in software development, specializing in the DevOps–FinOps intersection, Avihay brings deep expertise in cloud cost optimization. ☞ will speak about: In his talk, he will share actionable strategies for mastering resource cost management within AWS S3. **Paweł Kusiński:** Penetration Tester and Security Researcher focused on app and cloud security. His work includes penetration tests and infrastructure audits across a wide range of IT projects. Passionate about knowledge sharing, he leads workshops, gives conference talks, teaches at universities, and is an AWS Community Builder. Outside of work, he plays CTFs as a member of justCatTheFish and has an unhealthy habit of buying too many Legos - despite having absolutely no space left for them. ☞ will speak about: Time goes by, AWS keeps adding new security features, and yet year after year, we hear about more data leaks and breaches involving S3 buckets.

We’ll walk through the most common methods and configuration mistakes - and if time allows, we’ll try to secure everything properly as well! And who knows - maybe we'll uncover a million-dollar leak during the presentation?

Zapraszamy na trzy dwudziestopięciominutowe rundy medytacji, w trakcie których będzie okazja doświadczyć swojej pełnej obecności w tym-co-jest z-chwili-na-chwilę.

Let's grab some coffee/food and share a morning chat! The East Market has an ample parking lot and outdoor and indoor seating. Grab a cup of coffee from Winston's Coffee & Waffles or on your way to East Market and meet us on the second floor - table behind or east of the elevator. Per what this group is about: "Everyone is welcome! International transplants to Columbus who want to improve language skills, Columbus residents who want to discuss international travel and culture, and anyone who enjoys getting together for good conversations."

Welcome, readers! Our March read is **_The Bean Trees by Barbara Kingsolver._** The story follows Taylor Greer, a young woman from rural Kentucky who leaves home for the West, only to find herself unexpectedly becoming the guardian of an abused Native American toddler named Turtle. In Tucson, Arizona, they form a makeshift family with a diverse group of people, including Guatemalan refugees and a single mother, exploring themes of motherhood, community, belonging, and finding hope in hardship. The story blends humor with serious issues, creating a story about finding family in unexpected places. Looking forward to discussing with everyone! We will meet at Zaftig Brewing Co in their event room in the back. We are welcome to bring in our own food, but **drinks must be purchased at the bar.** Happy reading! 📖

Inspired by our successful events like "Saturday Mornings @ East Market" and other "Pot Luck in the Park" lunches, this gathering promises to be a blend of fun conversations, language exchange, and cultural insights, all while sharing wonderful foods with each other. Please bring a dish to share and anything you would like to drink. We will provide plates, plastic silverware and napkins. So, come hungry and ready to chat!

By popular demand, we're reserving a special meeting to watch the Oscars at Studio 35...
