AWS June 2016 Webinar Series - Best Practices for Architecting Cloud Backup a...Amazon Web Services
Cloud backup is an ideal application for taking advantage of the low cost and extreme scale of cloud storage. Traditional tape and disk solutions require up-front purchase, regular capacity management and ongoing maintenance. This webinar will help you understand cloud backup options, and how they fit into your organizations. We will also share some overall design considerations.
Learning Objectives:
Learn how to choose a storage platform (object, block or file)
Learn how to optimize your storage tier (S3, SIA or Glacier)
Learn how to ingest data into AWS storage (Direct Connect et al)
Understand the AWS storage partner options
Learn about the design lifecycle management policies, and archive and compliance considerations
We used Amazon’s Elastic Compute Cloud service to dramatically speed-up Pret a Manger’s PeopleSoft implementation. It improved our access requirements, reduced infrastructure costs and gave us access to more powerful servers and greater resilience than we’d otherwise have been able to afford. I’ll walk you through the initial decision, explain how everything was set up and demonstrate the benefits delivered to the project. I’ll also describe other occasions where the flexibility of Amazon EC2 has been invaluable.

Deep Dive on Deep Learning with Apache MXNet - AWS Summit Tel Aviv 2017Amazon Web Services
Deep learning continues to push the state of the art in domains such as computer vision, natural language understanding, and recommendation engines. One of the key reasons for this progress is the availability of highly flexible, and developer friendly deep learning frameworks. Apache MXNet is a fully-featured, flexible, and massively scalable open source deep learning framework that supports innovative deep models, including convolutional neural networks (CNNs) and long short-term memory networks (LSTMs). This session will show you how to use the AWS Deep Learning AMI and Cloud Formation template to deploy and train your own deep neural network, using MNIST, to recognize handwritten digits and test it for accuracy as a practical introduction to Apache MXNet.

Building Cloud-Native Applications with Microsoft Windows AzureBill Wilder
Cloud computing is here to stay, and it is never too soon to begin understanding the impact it will have on application architecture. In this talk we will discuss the two most significant architectural mind-shifts, discussing the key patterns changes generally and seeing how these new cloud patterns map naturally into specific programming practices in Windows Azure. Specifically this relates to (a) Azure Roles and Queues and how to combine them using cloud-friendly design
patterns, and (b) the combination of relational data and non-relational data, how to decide among them, and how to combine them. The goal is for mere mortals to build highly reliable applications that scale economically. The concepts discussed in this talk are relevant for developers and architects building systems for the cloud today, or who want to be prepared to move to the cloud in the future.
This talk was delivered by Bill Wilder at the Vermont Code Camp 2 on 11-Sept-2010.

This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.

Qu’est-ce que le sens du Cloud Computing? Ce nom, on peut traduire à français – la technologie informatique dans les nuages.
Comme la nuage n’a pas une forme constante, est-ce que on peut faire la même conclusions avec ça – la technologie?
La Réponse – La technologie signifie une mouvement dans l’industrie qu’on peut virtualiser les ressourcés locaux, par exemple, les mémoires vivantes, les processeurs, les bandes passantes, et le obtenir lorsque une nouvelle demande apparaît.
Nous volons discuter les joueurs dans cette domaine.
Le sens / la direction de cette industrie
Faire une démonstration de la technologie avec Amazon Web Services (AWS)
Combine de personne ici utilise un portable Mac comme moi?
Est-ce qu’on peut tourner les logiciels Windows sur le Mac? – VMWare Fusion, Parallel Desktop, XenBox, VirtualPC.
Y a-t-il quelqu'un qui a déjà construit une web site avec PHP, Java, CGI, Ruby On Rails, ….?
Lui demande sa expérience, …
Les difficultés, l’éffort, …
La promesse du Cloud Computing – on pourrait / puisse obtenir les ressourcés de calcules sur la demande, par exemple, les mémoires vivantes, les processeurs, et les bandes passantes, si la nouvelle demande apparaît. C’est l’histoire ancienneté qu’on a besoins de acheté « les boîtes » - un autre nom pour l’ordinateur, parce qu’ils sont cher et aussi n’est pas souple -> Le prix pour l’investissement de équipements est élevé; et, les équipements deviennent aussi obsolete plutôt rapide.
Les avantages:
Économiser -> le prix est variable et ne pas fixe. Pourquoi payer pour les choses dont vous n’avez pas besoin? Ce n’est pas de bon sens pour acheter les ressources dont on n’a pas besoins.
La vitesse est excellente – Les discs durs sont vraiment des fichiers. Il est plus rapide pour ouvrir / enregistrer une fichier que plusieurs fichiers.
Très fiable – J’ai plus confiance à « cloud computing » que mon ordinateur – la batterie, la température, les virus, … AWS a sa propre très bons systèmes sauvegardes que moi.
Monter à charger (Scalability) est très facile – On peut ajouter les ressources si on veuille.
Le processus est définitif est facile à documenter.
Les ressourcés de calcule comme l'électricité. Je profite de l’énergie sans les problèmes d’opérer une centre électrique.
D’abord, je vous présente la modelé classique. C’est la AWS, qui a commencé l’opération depuis 2002. Avec AWS, on a une Centre de traitement de données (datacenter) sauf le prix et les responsabilités. Presque toutes les activités managements, on peut commander par le Navigateur Web (browser). Par exemple:
Ajouter plusieurs de stockage
Démarrer/Redémarrer des novelle instances de la machine
Terminer une instances de la machine
Convertir une machine virtuelle par un fichier dans le formate de S3.
Attacher des nouvelles adressées à une machine virtuelle qui est tourner maintenant
Monter à charger par ajouter plusieurs machines virtuelles.
Pour quoi est-ce que le Cloud Computing important pour les étudiants informatique?
Après 2008, il y a plus de la trafique du web qui a origine du AWS que le site principal du Amazon.
Il y a plus de 103 milliards de S3 objets, depuis 2009.
Il y a plus 500 milliards membres actives pour le réseau social - Facebook.
Moi avec le fondateur de Facebook
C’est très difficile à prévoir la demande.
Si nous sommes réussi avec la prédiction d’avenir, chaque personne doive jouer la loterie.
L’utilisation de système est jamais fois constant! Il régulé comme une fonctionne du temps.
-------------------------
This is a real usage graph from one of our financial services customers during the last week of April (They have asked to remain anonymous for competitive reasons). Firms on Wall Street are finding EC2 an ideal environment to run many of their daily mission critical grid computing and cpu bound applications for a couple key reasons: 1/ Flexibilitythe ability to instantly access hundreds/thousands of cores increases the amount of data they can process, improving the overall quality of their models. and 2/ Cost efficiencies, as they can complete more of their processing for less total spend (Not paying for infrastructure during times of the day and weekends when its not needed)
This wall street firm in particular has a nightly business process where they upload the day’s market trading data into S3, and then run proprietary ‘risk management’ algorithms. This lasts ~10 hours during week nights, where they ramp up to the equivalent 3000 m1.smalls.
During the day and on weekends, they maintain a base of roughly 300 cores, to handle their always on work loads.
Les éléments de AWS sont représentes par l’image au dessus. Pour expérimenter, il faut comprendre
EC2 – La machine virtuelle
S3 – La system du Storage
EBS – opérer comme un disc dur
Simple DB – Une base de données, qui est très simple sans schémas.
---------------------------------------------------------
Amazon Web Services is a set of primitive building blocks to enable developers to build applications and, ultimately, businesses, on our battle-tested infrastructure. So what kinds of building blocks do developers need?
First, you need compute resources. The Elastic Compute Cloud, or EC2, allows developers to rent virtual computers, running in our data centers, and pay for them by the hour. Provision as many as you need – 1, 10, 1000, for as long as you need them, and you pay only for what you use (starting at 10 cents/hour).
Next, you probably need somewhere to durably store and retrieve data. The Simple Storage Service, is, well, a simple storage service that allows to store and retrieve objects in the cloud using simple put and get API calls.
You might need to index and query for that data, or create other structured data that you want to query, which is what we built SimpleDB.
