Load balancing as a Service (Infra) Database as a Service (Platform) MyApplication as a Service (Software) etc. 3 . 13 SERVICE MODELS IN ONE DIAGRAM IaaS - PaaS - SaaS (source: Wikipedia) 3 . 14 PUBLIC OR PRIVATE CLOUD? Who is it for? Public: everyone, available on internet Private: to an organization, available on its network 3 . 15 HYBRID CLOUD Usage of multiple public and/or private clouds Attractive concept but implementation is hard a priori Some use cases fit perfectly Continuous integration (CI) Incentives: Avoid lock-in Cloud bursting 3 . 16 VIRTUALIZATION INSTANT Let's make it clear. Virtualization is a technology that can implement the compute function A cloud providing compute resources can use virtualization But it can also use: Bare-metal Containers 3 . 17 APIS ARE KEY Reminder: API stands for Application Programming Interface In the software sense: Interface for a program to use a library In the cloud sense: Interface for a program to use a service (XaaS) Programming interface (through the network, often HTTP) Explicit boundary between the provider and the user Defines how the user interacts with the cloud to manage their resources Manages: CRUD (Create, Read, Update, Delete) 3 . 18 API REST One ressource == one URI (Uniform Resource Identifier) Usage of HTTP verbs to define operations (CRUD) GET POST PUT DELETE Usage of HTTP return codes Resources are represented in the HTTP responses' body 3 . 19 REST - EXAMPLES GET http://endpoint/volumes/ GET http://endpoint/volumes/?size=10 POST http://endpoint/volumes/ DELETE http://endpoint/volumes/xyz 3 . 20 REAL EXAMPLE GET /v2.0/networks/d32019d3-bc6e-4319-9c1d-6722fc136a22 { "network":{ "status":"ACTIVE", "subnets":[ "54d6f61d-db07-451c-9ab3-b9609b6b6f0b" ], "name":"private-network", "provider:physical_network":null, "admin_state_up":true, "tenant_id":"4fd44f30292945e481c7b8a0c8908869", "provider:network_type":"local", "router:external":true, "shared":true, "id":"d32019d3-bc6e-4319-9c1d-6722fc136a22", "provider:segmentation_id":null } } 3 . 21 WHY CLOUD? ECONOMICAL POINT OF VIEW Consider IT resources as service provider resources Shift the "investment" budget (Capex) to the "operation" budget (Opex) Cut costs by sharing resources, and maybe with economies of scale Reduce delivery times Match costs to the real usage of resources 3 . 22 WHY CLOUD? TECHNICAL POINT OF VIEW Abstract from the lower layers (server, network, OS, storage) Get rid of the technical administration of resources and services (DB, firewalls, load-balancing, etc.) Design infrastructures which can scale on the fly Act on resources through lines of code and manage infrastructures "as code" 3 . 23 MARKET 3 . 24 AMAZON WEB SERVICES (AWS), LEADER AWS logo Started in 2006 At first: "e-commerce" web services for developers Then: other services for developers And finally: infrastructure resources Recently, SaaS 3 . 25 PUBLIC IAAS ALTERNATIVES TO AWS Google Cloud Platform Microsoft Azure Rackspace DreamHost DigitalOcean In France: Cloudwatt (Orange Business Services) Numergy (SFR) OVH Ikoula Scaleway Outscale 3 . 26 PRIVATE IAAS OpenStack CloudStack Eucalyptus OpenNebula 3 . 27 OPENSTACK IN A FEW WORDS OpenStack logo Was born in 2010 OpenStack Foundation since 2012 Written in Python and distributed under Apache 2.0 license Large support from the industry and various contributions 3 . 28 PUBLIC PAAS EXAMPLES Amazon Elastic Beanstalk (https://aws.amazon.com/fr/elasticbeanstalk) Google App Engine (https://cloud.google.com/appengine) Heroku (https://www.heroku.com) 3 . 29 PRIVATE PAAS SOLUTIONS Cloud Foundry, Foundation (https://www.cloudfoundry.org) OpenShift, Red Hat (https://www.openshift.org) Solum, OpenStack (https://wiki.openstack.org/wiki/Solum) 3 . 30 INFRASTRUCTURE AS A SERVICE CONCEPTS 3 . 31 BASICS Infrastructure: Compute Storage Network 3 . 32 COMPUTE RESOURCES Instance Image Flavor Keypair (SSH) 3 . 33 INSTANCE Dedicated to compute Short typical lifetime, to be considered ephemeral Should not store persistent data Non persistent root disk Based on an image 3 . 34 CLOUD IMAGE Disk image containing an already installed OS Infinitely instanciable Can talk to the metadata API 3 . 35 METADATA API http://169.254.169.254 Available from the instance Provides informations about the instance Exposes userdata The cloud-init tool helps take advantage of this API 3 . 36 FLAVOR Instance type in AWS Defines an instance model regarding CPU, RAM, disk (root), ephemeral disk The ephemeral disk has, like the root disk, the advantage of often being local and thus fast 3 . 37 KEYPAIR SSH public key + private key Cloud manages and stores the public key This public key is used to give SSH access to the instances 3 . 38 NETWORK RESOURCES 1/2 L2 network Network port L3 network Router Floating IP Security group 3 . 39 NETWORK RESOURCES 2/2 Load Balancing as a Service VPN as a Service Firewall as a Service 3 . 40 STORAGE RESOURCES Cloud provides two kinds of storage Block Object 3 . 41 BLOCK STORAGE Volumes that can be attached to an instance Access to raw devices such as /dev/vdb Ability to use any kind of file system Ability to use LVM, encryption, etc. Compatible with all existing applications Requires provisioning space by defining volume size 3 . 42 SHARED STORAGE?

  • IP Spoofing in and out of the Public Cloud
    computers Article IP Spoofing In and Out of the Public Cloud: From Policy to Practice Natalija Vlajic *, Mashruf Chowdhury and Marin Litoiu Department of Electrical Engineering & Computer Science, York University, Toronto, ON M3J 1P3, Canada; [email protected] (M.C.); [email protected] (M.L.) * Correspondence: [email protected] Received: 28 August 2019; Accepted: 25 October 2019; Published: 9 November 2019 Abstract: In recent years, a trend that has been gaining particular popularity among cybercriminals is the use of public Cloud to orchestrate and launch distributed denial of service (DDoS) attacks. One of the suspected catalysts for this trend appears to be the increased tightening of regulations and controls against IP spoofing by world-wide Internet service providers (ISPs). Three main contributions of this paper are (1) For the first time in the research literature, we provide a comprehensive look at a number of possible attacks that involve the transmission of spoofed packets from or towards the virtual private servers hosted by a public Cloud provider. (2) We summarize the key findings of our research on the regulation of IP spoofing in the acceptable-use and term-of-service policies of 35 real-world Cloud providers. The findings reveal that in over 50% of cases, these policies make no explicit mention or prohibition of IP spoofing, thus failing to serve as a potential deterrent. (3) Finally, we describe the results of our experimental study on the actual practical feasibility of IP spoofing involving a select number of real-world Cloud providers. These results show that most of the tested public Cloud providers do a very good job of preventing (potential) hackers from using their virtual private servers to launch spoofed-IP campaigns on third-party targets.

  • Kalray, Vates and Scaleway Announce Collaboration to Develop and Deliver Virtualization Solutions Powered by Acceleration Dpu-Based Cards
    KALRAY, VATES AND SCALEWAY ANNOUNCE COLLABORATION TO DEVELOP AND DELIVER VIRTUALIZATION SOLUTIONS POWERED BY ACCELERATION DPU-BASED CARDS The companies intend to provide a power-optimized and energy-saving virtualization stack using Kalray's acceleration cards and targeting data-intensive applications. Grenoble / Paris - France, July 12,2021 - Kalray (Euronext Growth Paris : ALKAL), a leading provider in the new generation of processors specialized in Intelligent Data Processing from Cloud to Edge, Vates, an open source software company specializing in secure and open source virtualization, and Scaleway, the leading French and European alternative IaaS and PaaS provider and Bare Metal pioneer, announce their collaboration to promote an energy-optimized and secure environment in data centers. This first collaboration will combine Kalray's new K200-LP™ acceleration card, incorporating Kalray's latest generation MPPA® DPU Coolidge™ processor, with Vates' optimized XCP-ng open source virtualization solution to create a secure, performance-optimized virtualization stack targeting data-intensive applications. This stack could be operated and managed by vendors, particularly French or European sovereign vendors in Scaleway's ultra-high performance environmental data centers. Virtualization environments have been a huge success for more than a decade in the data center world by allowing a large number of virtual machines to run on a single physical machine. These environments are now widely deployed both in the Cloud and in on-premise data centers. However, the hypervisor, the software part that is at the heart of these environments, must evolve to continue to be more efficient in terms of performance and energy consumption, while being more flexible and more secure.

  • SOLUTION CLOUD : LAQUELLE CHOISIR ? Cloud Radar - AWS, Azure, Google Cloud Avant-Propos
    SOLUTION CLOUD : LAQUELLE CHOISIR ? Cloud Radar - AWS, Azure, Google Cloud Avant-propos Pourquoi cette étude ? La documentation sur le sujet du cloud devient pléthorique, mais il est malheu- reusement rare de trouver une ressource indépendante, objective et com- parative. En effet, les différents acteurs mondiaux du Cloud ont des histoires et des philosophies très différentes, qui les ont poussés à proposer des outils eux-mêmes uniques. Nous retrouvons bien évidemment des points communs à tous, comme la ca- pacité de démarrer des serveurs virtuels, plus ou moins spécialisés, mais cela ne constitue que la base de ces services. À l’inverse, c’est ce qui différencie ces fournisseurs qui est le plus intéressant. Comme nous allons le voir, les clouds proposent des services souvent com- parables, mais pas équivalents pour autant. Amazon Web Services offre une palette de service quasi infinie, est le roi du micro service, mais à des coûts souvent plus élevés que ses concurrents, et n’offre pas toujours les meilleures performances selon l’usage ciblé. Si vous êtes dans l’analyse de données, le fameux “Big Data”, l’intelligence artificielle, ou le container, Google Cloud Platform sera plus adapté. Si vous êtes déjà très empreint de culture Microsoft, Azure pourrait s’imposer. Il n’y a donc pas “un” cloud ou “le” cloud, mais plusieurs infrastructures avec chacune leurs forces et leurs faiblesses. Le but de cette étude comparative est, à ce titre, de mettre en lumière ces différences afin de vous guider dans le choix du bon cloud, selon vos enjeux et vos besoins. Sommaire Une étude indépendante et scientifique Oceanet Technology souhaite souligner qu’aucune rémunération, sous aucune forme directe ou indirecte, n’a été perçue par l’équipe d’auteurs ou la société.

  • Scaleway Dc5 Data Center Case Study
    SCALEWAY DC5 DATA CENTER CASE STUDY INDUSTRY: TELECOMMUNICATIONS, INTERNET HOSTING, CLOUD COMPUTING CUSTOMER: Scaleway SAS, DC5 Datacenter LOCATION: Saint-Ouen-l’Aumône, France BACKGROUND: Scaleway is an IT solutions provider that delivers hosting, cloud, colocation, and managed services to customers in the Paris metro region. As one of the largest data center operators in Europe, Scaleway designs, builds and operates data center infrastructures and manages over 60,000 square meters of reliable, e cient, secure data center space. Scaleway’s new hyperscale data center, DC5. Scaleway selected an old, strategically located mail sorting o ce in a popular business and industrial park near Paris to convert into the new DC5 facility. PROBLEMS Reliable, cost-e ective, year-round cooling that met the company’s pressure drop TO SOLVE: requirements was a top priority for Scaleway’s new data center, DC5. Cooling was crucial to the design of Scaleway’s DC5. The facility is located in France, where the climate is temperate and air conditioning is uncommon. Europe’s recommended maximum PUE of 1.3 for new data centers had to be met, and Scaleway’s goal was to be below 190 Pa at 925 ft/min (4.7 m/s). Finding a solution below 200 Pa was a challenge. WHY ARMSTRONG?: Only Armstrong’s customized, best-in-class adiabatic cooling technology could deliver the high level of performance Scaleway required. Scaleway turned to Armstrong’s EvaPack™ because its innovative adiabatic process enables 100% of the outside air to evaporate through a cooling and humidifi cation system. Armstrong’s solution o ered the dependable cooling and precise control of relative humidity required to maintain an optimum data center environment—while meeting the company’s goals for e ciency and cost.
