Kicked off @AWSreInvent 2019 by attending @houlihan_rick’s @DynamoDB modeling session. As expected, it was a 60 minute firehose of #NoSQL knowledge bombs. There was *A LOT* to take away from this, but here are some really interesting lessons that stuck out to me. #reInvent
DynamoDB performance gets BETTER with scale. Yup, you read that correctly, the busier it gets, the faster it gets. This is because, eventually, every event router in the fleet caches your information and doesn’t need to look up where your storage nodes are.
Big documents are a bad idea! It’s better to split data into multiple items that (if possible) are less than 1 WCU. This will be a lot cheaper and cost you less to read and write items. You can join the data with a single query on the partition key.

Over the last months, we improved our @OVHcloud Public Cloud ecosystem with our vision + your requests and feedbacks.
Fasten your seatbelt, here is a recap ! 🔽
Reminder: Public Cloud = bricks like compute, storage, network, PaaS, services,... sharing some concepts like pay-what-you-consume-only, usually mgmt by project, API everywhere and sharing physical hosts between multiple customers. But your VMs (called instances) are for you only
Let's start with compute. We now provide IOPS instances with high-perf SSD #NVMe disks.
#ELK, #Hadoop, #NoSQL ? Perfect uses-cases for them :) Trust me they "dechire grave" as we say here.
FIO benchmarks vs competitors = specifc thread soon :)

بمناسبة اليوم الوطني راح أهديكم سلسلة تغريدات ألخص فيها تجربتي مع منصة #فايربيس @Firebase
فايربيس هي منصة للمبرمجين وخصوصا مطوري التطبيقات تملكها قوقل @Google وهذا رابط المنصة firebase.google.com
لماذا فايربيس؟ فايربيس عبارة عن منصة باكاند backend متكاملة توفر لمطوري التطبيقات عدة خدمات على رأسها ١) ادارة المستخدمين firebase authentication و ٢) قاعدة بيانات #فايرستور #Firestore و ٣) تحليلات فايربيس اناليتكس firebase analytics لتحليل سلوك مستخدمي التطبيق
ايش يفرق فايربيس عن خدمات أخرى مثل قوقل كلاود او أمازون كلاود او غيرها؟
الفرق الرئيسي والأساسي هو انك تحصل على الباكاند من فايربيس كخدمة backend as a service او #BaaS بدون ما تكتب ولا سطر كود خارج تطبيقك. هذا لا يعني انك راح تستغني بشكل كامل عن كتابة كود باكاند زي ما راح نشوف

I've been spending a lot of time lately with @dynamodb in my #serverless applications, so I thought I'd share my surefire guide to migrating to it from #RDBMS. So here is…

How to switch from RDBMS to #DynamoDB in *20* easy steps… (a thread)
STEP 1: Accept the fact that Amazon.com can fit 90% of their retail site/system’s workloads into DynamoDB, so you probably can too. 🤔
STEP 2: Create an Entity-Relationship Model, just like you would if you were designing a traditional relational database. 👩‍💻

Bir yazılım geliştiricinin bilmesi gerekenlerle ilgili 15 maddelik flood geliyor.. Mümkün olduğunca fazla keywordü bir araya toplamaya çalıştım.
Hadi Başlıyoruz!

#Developer #Software #Java #code #kod #yazılım #development #computer #bilgisayar #tool #PC #IT #web #tech #data
1-Temel veri yapıları (linkedList, map, tree vb) ve temel algoritmalar (sıralama, arama vb)

Sıfırdan kodlama ihtiyacınız büyük ihtimalle hiç olmayacak. Ancak ihtiyaç anında doğru yerde doğrusunu seçebilmek için o veri yapısının veya algoritmanın nasıl çalıştığını bilmeniz şart
2- Network Temelleri

OSI Modelini ve 7 katmanı; temel protokolleri(#TCP-IP, TCP-UDP, #HTTP, #FTP), güvenlik protokollerini(#HTTPS, #SFTP, #SSL), monitoring protokolleri(#SNMP, ICMP) bilmekte fayda var. Ayrıca ağ ekipmanlarının görevlerini tanımak ve 7Layer yerlerini bilmek lazım

Here's what happens when the combined prowess of #CSV #RDF intersect i.e., generation of a #SemanticWeb of #LinkedData visualized using our #HTML5 #PivotViewer: linkeddata.uriburner.com/HtmlPivotViewe…

This is an utlra flexible visual drill-down :)

#DataVisualization #GraphDatabases #RDBMS
Here's a post that explains how our #HTML5 #PivotViewer functions in conjunction with #SPARQL re. powerful #DataVisualization that leverages a #SemanticWeb of #LinkedData.
